Computer Network Fundamentals

Computer Network Fundamentals Harpreet Singh   Elements of computer communication. Computer Communication plays vital role to connecting two different devices and share the common information with each other and this information can be anything like text or video. To communicate from one computer to other it required some essential elements i.e. sender, receiver, medium, message and protocol. The Main parts or components of Data communication system are as Follows:- Sender Message Receiver Medium [ Communication channel ] Protocols Sender. The initial stage of communication is starts with sender. Sender is the person or machine who sends the message or start communicate with other devices. Sometime it is also called as transmitter. Message The secondary stage is creating message or idea and statement is to be communicated. A message can be verbal, text, number, picture etc. Medium [Communication channel] Medium is the intermediate of the communication channel. In other way medium is the technique which transmitted message from a sender to receiver. It is also called communication channel.   The source used in medium can be a wire, fibre or optical cable and telephone lines etc. Receiver Receiver is the person or the device which receives the message send by sender. The receiver can be a computer, printer, email or telephones etc. Protocol Protocols can be defined as a gathering of strategies which oversee correspondence of information between the PCs. Some protocol which are very commonly used in communication are HTTP(Hypertext transfer protocol), FTP(File transfer protocol), SSL(Secure socket layer) , TCP(Transmission control protocol),PPP(Point to point protocol). Identify the types of transmission:- Types of Transmissions Transmissions is transferring information between two devices. Basically there is three modes of transmissions i.e. simplex, half duplex, full duplex and these transmissions modes can also called as communication modes. However unicast, multicast, broadcast is also consider as transmissions. (Study tonight, n.d.) Simplex: In this mode data can be transmitted only via one way i.e. communication is unifacial. We cannot send back data to the Sender. The best example of simplex mode is Televisions and remotes. Half Duplex: In this mode data can be transferred from both sides but only one at a time, which means when the sender sends the data at the same time receiver cannot send the message to sender. For instance walkie talkie in which we transmit information one at a time and that information sent in the both ways. (Study tonight, n.d.) Full Duplex: In full duplex data can be transmitted from both directions, so it means it is two way communication. In this sender can sent message at the same time receiver also send message. The example of full duplex is Mobile phone in which both user can talk. (Study tonight, n.d.) Unicast:   Unicast is the transmission between a single sender and single receiver. For example browsing a website. Multicast: Multicasting is the transmission where a group of receivers wants to transmit with single sender. For example Wi-Fi in which there are multiple user access single medium i.e. Wi-Fi. Broadcast: Broadcasting is when we send message to multiple user and they all are able to read that same message this is called broadcasting. For watching T.V in which multiple user access a same program which is broadcast. Identify the types of transmission for the following use cases: Mr Smith is walking in the street and looking for a residence address. He is new in this city and do not understand the address code of residence. Then he asked a pedestrian Do you know where this is? This is the Unicasting transmission in which there is a new person ask to another person for address so it means there is single and single receiver. Lecturer said student with odd number student ID will join in STREM A. This is Multicasting transmission in which Lecturer is a sender and students with odd number are the group of receiver. Lecturer delivers the lecture in the class room. This is also Multicasting transmission in which lecturer is a sender and group of receiver is the student who access his lecture. Watching a TV. This Broadcasting transmission in which multiple user access same program. Two police men communicate with each other over walkie-talkie. This is the Half-duplex transmission in which a single information is transmitted at a time and information is send in the both ways. Mr John made a phone call to his wife that he will be late today. This is Full-Duplex transmission in which date is transmitted from both ways. (A) Describe the difference between packet and circuit switching. Circuit Switching When the two machine communicate over a specific communication path, it is called as circuit switching. There is always required pre-described route from where data should be move and no other data is allowed. In circuit switching to transmit the data firstly circuit must be established so that data can be transmitted. There are three phases from which all the application using circuit switching have to pass through: 1 Establish a circuit 2 Transfer the data 3 Disconnect the circuit Circuit switching was intended for voice applications. Phone is the best reasonable case of circuit switching. Prior to a client can make a call, a virtual way amongst guest and call is set up over the system. (Tutorials point, n.d.) Packet Switching (PS) In packet switching the whole message is separated into small pieces is known as packet switching. The switching data sum up in the header of each packet and exchange separated. It is always easier to all devices in the network which are intermediate with each other to store small size packets. As we can see in the figure packet can follow any path to reach the destination. Best suitable example for packet switching is internet. Packet switching the internet uses packet switching technique. Packet switching enables the user to differentiate data streams based on priorities. Packets are stored and forwarded according to their priority to provide quality of service.(Tutorials point, n.d.) DIFFRENCE BETWEEN PACKET SWITCHING AND CIRCUIT SWITCHING(rfwireless-world, n.d.) Describe the multiplexing Network. There are many multiplexing networks. Network multiplexing list is below. Time Division Multiplexing:- TDM is applied principally on digital signal yet can be applied to analog signal also. In TDM the common channel is isolated among its client by the method of the time slot. Every client can transmit information inside the given time slot only. Digital signals are isolated in frames, proportionate to time slot i.e. frames of an ideal size which can be transmitted in given time slot. Frequency-Division Multiplexing:- In FDM every signal is allocated its own particular frequency range inside a bigger frequency band. The frequency range for the channel cannot cover. Frequency bands are regularly isolated by an unused block of the frequency range to diminish interference. FDM is utilized mostly for simple transmissions. It can be utilized over both wired and remote mediums. The best example of FDM is FM radio. Code-Division Multiplexing:- Multiple data signal can be transmitted over a solitary frequency by utilizing code division multiplexing. FDM isolates frequency into the small channels yet CDM permit its clients to full bandwidth and transmit the signal all the time utilizing remarkable code. CDM always uses orthogonal codes to spread signals. Wave-Division Multiplexing:- Light has the diverse wavelength (colors). In fibre optic mode, various optical transporter signs are multiplexed into an optical fibre by utilizing diverse wavelengths. This is a simple multiplexing method and is done adroitly in an indistinguishable way from FDM, however, utilizes light assigns. Describe the Performance Factor. Latency:- The term Latency to any of a few sorts of postpones commonly brought about in handling of system information. A network connection that phases a little delay time is knows as low latency, on other side high latency is totally opposite of low latency in which network experienced long delay. Throughput: Throughput is the bulk of traffic which a network can tackle at any one time. For example higher the lanes on the motor way it will accommodate higher traffic as similar in the network if the bit rate is higher than it will transfer the data at higher rate but responding time would be the issue if the response is slow then your network might be not having the enough throughput. (Blog Wildpackets, n.d.) Bandwidth:- Bandwidth is defined as a range with in a band of frequencies or wavelengths (Webopedia, n.d.). Bandwidth describes the speed rate of the network and the maximum data is transfer if the bandwidth of the network is higher. Jitter:- Jitter is basically delaying of packets to reaches its destination at different time and the order in which packets were send may be disorder. In other words loss of voice packets while communicating with other person is caused by the jitter. Response time:- Response time is the elapsed time between an inquiry on a system and the response to that inquiry. (Techopedia, n.d.) Response time is the time that shows the users are accurately exchanging the information or devices are connect with each other. Describe the types of network based on geographical. Local Area Networks (LAN):- A Local Area Networks (LAN) as name shows it will cover only a local area a smaller part of an area like a small office, school or a house. A LAN transfer data at much higher than MAN WAN. A LAN can be install in two ways either wired or wireless based on Ethernet. Sharing of storage, printer and common files is possible on LAN but there is the possibility of conjunction because if all the users access these resource on the same time on the single LAN then it will take some time.  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚     Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚     Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚     Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚     Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€š   Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚     Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚     Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚     Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚     Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚     Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚  Ãƒâ€šÃ‚   (Udemy, n.d.) Metropolitan Area Network (MAN):- Metropolitan Area Network (MAN) usually cover the larger area as compared to LAN. It will cover the cities or small towns or organization to provide higher speed of data transmission. MAN is used when you want to connect two or more computer to communicate with effective speed. The technologies used in MAN is ATM (Asynchronies Transfer Mode), FDDI (Fibre Distributed Data Interface) etc. (Udemy, n.d.) Wide Area Network (WAN):- Wide Area Network (WAN) is usually cover higher geographical are like cities, countries, towns. WAN is the mixture of the LAN and MAN which are interconnect with each other so that the user who wants to communicate from different places are able to send data or information at higher speed. WAN is connected through satellite, public network etc. WAN is usually very expensive as compared to other networks. (Udemy, n.d.) Blog Wildpackets. (n.d.).

War and Terror - It’s Time to Stop the Killing :: Argumentative Persuasive Argument Essays

War and Terror - It’s Time to Stop the Killing Somewhere within the last 120,000 thousand years, our ancestors began migrations quite different from any that appear in the archeological record preceding that time and somewhere between forty and fifty thousand years ago those migrations accelerated to the point that Cro Magnon hominids, our forebears, settled every nook and cranny on the planet. The last major migration occurred when the land bridge opened up in Siberia, as the glacier receded ten thousand years ago, and Homo Sapiens, who our species had become by then, trudged all the way to Tierra del Fuego within a thousand years or so. Jared Diamond (â€Å"The Third Chimpanzee† & â€Å"Guns, Germs, and Steel†) makes a case for some biological change, probably related to speech, as the variable making such migrations possible. He also makes the observation that these human migrations were coincident with the extinction of large mammals. The archeological evidence seems to bear this out. All over the planet there is fossil evidence of the extinction of one large mammal after another at approximately the same time the human migrations happened in that part of the world. Some scientists speculate that the cause of these extinctions is more complicated than the fact that they are coincident with the expansion of the number of humans and they are probably right; but something of major proportions in the evolution of our species definitely changed to allow humans to sweep across all but the most uninhabitable places on earth in a relatively short period of time. Dr. Diamond is careful to temper his speculation with the caution that all the facts are not yet in, and probably never will be, I might add. As a biology-oriented scientist, he continues to look to some physical/anatomical change to account for the advances made by humans resulting in our capacity to take on the unknown dangers lying beyond the next range of mountains or across the next river. For a couple of million years humans had evolved fairly slowly toward that point when a â€Å"great leap† occurred in the pace of our development. Anatomically we are about the same now as we have been for the last 125,000 years, so the guess is that some language advancement made the difference.

Experiences of Child Poverty Essay

London is the capital of the United Kingdom. The administrative structure in Greater London consists of 32 counties (boroughs) and the City of London, extending over 1584 kilometers  ². The population of London is around 7.5 million however throughout Greater London about 13 million people live. The GDP per capita for The UK is $36,500. London is the richest part of Britain and yet it has the highest rates of poverty in the UK. Lagos is the largest city in Nigeria. With an estimated population of 8.8 million inhabitants in the city, or rather 10.7 million in the metropolitan area, Lagos is the second largest city in Africa. The UN estimates that at its present growth rate, Lagos state will be third largest mega city in the world by 2015 after Tokyo in Japan and Mumbai in India. Lagos is the main city of the south-western part of Nigeria, Africa. The GDP per capita in Lagos is $3,649. Over 10,000 people arrive at Lagos every week in search of jobs and most end up in the city’ s mega slum do to the lack of job opportunity. Children living in poverty are those who experience deprivation of the material, spiritual and emotional resources needed to survive, develop and thrive, leaving them unable to enjoy their lives, achieve their full potential or participate as full members of society. The easiest way to quantify child poverty is by setting an absolute or relative monetary threshold. If a family does not earn above that threshold, the children of that family will be considered to live below the poverty line. Absolute poverty thresholds are fixed, whereas relative poverty thresholds are developed with reference to the actual income of the population and reflect changes in consumption. This is not always accurate, as it is only an average and there are people earning millions who affect that average GDP per capita. In poor areas of London there are many problems that face children. The poor areas tend to be in places that lack jobs and job opportunities e.g. Hackney, Such poor areas can really affect the child’s life due to their living conditions. These children are living in relative poverty as they do have access to clean water, food and shelter which is provided by the state, but are considered poor to the rest of society as they can’t afford luxuries and normally depend upon benefits to get though life. These areas that lack job opportunities have high unemployment rates and so people have low incomes and often relate to crime as it is the culture of the area and people feel they do not get enough support from the government and feel let down and ignored. These poor areas are prime spots for drug dealers and drug addicts. This is significantly bad as they have a low income and so can’t afford the drugs and so they use the money which would have been spent on the children E.g. quality food. Rather than spending the money on better quality food they spend it on the drugs they are dependent on as they are addicted and so the child looses out as they tend to be mall nourished. Being mall nourished can increase the chances of becoming ill which then in turn means the child is less likely to spend time in school as they are off ill. This then affects their learning and they under achieve which means they have a less chance of ever getting a job and so they are trapped in the poverty cycle. It is then rely difficult for the children to break out of the poverty cycle due to many factors that affect them. Whereas Children living in the slums of Lagos also suffer from poverty, however the majority live in absolute poverty as they do not always have access to clean water, food and shelter, for example these children don’t have access to clean water and so most of the water is contaminated with diseases like cholera. Allot of children catch cholera from drinking dirty water which makes them ill and as most of the children have no access to health care due to their parents being born they can remain ill for a long time and it can be fatal. Being ill means they cannot help to provide for the family and the money being spent on their health cannot be spent on other vital things like basic food stuffs. It is hard to get out of both cases of poverty; however the children in the slums of Lagos are worse off and have a lower standard of living than the children living in Hackney. The majority of children living in poverty in Lagos are born to poor parents. Because of things like adult poverty, lack of education, unemployment, disabilities and discrimination significantly affect the causes of child poverty. Lack of parental economic resources such as disposable income restricts children’s opportunities and therefore the children are unable to go to school and allot of these children are forced to work. The problem is that allot of these jobs where children are forced to work are very dangerous and can cause injuries, health problems and even death. E.g. the recycling of old oil drums that contain harmful toxins. The main reason why the children in Hackney are trapped in the poverty cycle is because of the parents/Careers as well. The cycle of poverty is when a family remains in poverty over many successive generations. Family issues can play a big part in the reason for the child being submitted to a life of poverty. If the parents get in debt then this can be the cause of allot of stress, this can also cause the child to have stress which can affect their learning ability and health. Stress can also cause breakups between couples; this can lead to single mothers who are left on their own to support the child and themselves, which can also lead to father stress. Most single parents are unemployed because they haft to look after the children and so they rely on benefits. Teen pregnancies in both MEDC’s and LEDC’s are big causes of child poverty. Children resulting from unwanted pregnancies are more likely to live in poverty; raising a child requires allot of resources, so each additional child increases demands on parental resources. Families raised by a single parent are generally poorer than those raised by couples. This can be a big issue in LEDC countries such as Lagos. Many teens abandon their children as they simply do not have the resources available to support their child as they cannot claim benefits as they do not exist. Where as in MEDC’s, teen moms are supported by the government and family. The problem in Lagos is that children generally suffer from absolute poverty; however there is also relative poverty. With absolute poverty children generally do not have what they need. They are short of basic food, water, shelter, clothing and adequate or sufficient health care. Where as in Hackney people do not suffer from absolute poverty and so are better off, however they live in relative poverty that is poverty under relative terms is viewed as being what some people lack in relation to other people. In my opinion the worst experience of child poverty in Lagos would be the lack of Clean water which causes a significant amount of deaths and illnesses and affects the family as a whole as the money used to pay for the child’s healthcare comes from the money normally spent on other necessities like food or education. The government of Nigeria could provide communities with wells however it would cost a phenomenal amount of money , and the majority of the people don’t live on legal grounds as they have just moved there and have not actually paid to live there and so the government would not be allowed to build wells as most of the people don’t have permition to live there in the first place. The worst experiences for children living in Hackney would be the culture of the area and so children grow up with crime related experiences, this then means that most of the children get brought up with crime and this can keep them in the poverty cycle. The government of Britain could increase prison sentences and increase policing in these areas. This policy would be expensive however it would increase the standards of living for these people and help them get out of relative poverty. Both cases of poverty affect the child’s opportunities in life. This means they are limited jobs available to them or unemployment if there is a lack of job opportunities. There future generations will probably also live in poverty, whether absolute or relative. They will rarely experience if at all the luxuries and experiences we take for granted. Their only hope getting out of poverty is if the government adopts a poverty reduction strategy paper (PRSP) and use schemes like the growth of the cities and urban development, employment opportunities and poverty reduction and housing schemes. Also the best way to reduce child poverty would be to reduce child labour and increase accessibility to education by building more schools and improving the quality of education. This is a key point that governments need to adopt in order to reduce child poverty and help break the poverty cycle.

Chemistry Personal Statement Essays

Chemistry Personal Statement Essays Chemistry Personal Statement Essay Chemistry Personal Statement Essay Students who are studying their Masters course would already know the significance of writing an appealing Chemistry personal statement. They have had their share of experience of writing these difficult statements just like any other undergraduate. A personal statement or a statement of purpose helps the applicant in distinguishing his application from dozens of other candidates who have applied for the same course. It provides a huge opportunity to the candidate to leave aside his academic test scores and impress the board with his/her unique skills, qualities and personality. Even a student with high test scores or GPA cannot certainly feel confident in getting the seat in the university. Therefore, the only way one can ensure a seat in the university is by setting himself apart by submitting an appealing and attractive chemistry personal statement. Dozens of applications get rejected each year because of poorly written content and poorly defined thoughts. Students will only be able to impress the board of the university if they consider it carefully what sorts of ideas should be included in the statement and how to express those ideas in an appealing manner. This may probably seem quite intimidating at first but once you sit down and pen down those ideas in a proper order you will see that how easy it is to write a good statement. It is also recommended that every applicant should make an outline so that he can gather and express his thoughts in an effective manner. First outline the introduction of the statement and consider including those important elements in it that can catch the attention of the board. For example, you can start with your childhood dream to become a chemical engineer. While outlining the elements that are to be included in the body section of the statement, consider those points that needs a complete description. For instance, you can link the academic qualification with your interest in the chemistry field and how that qualification can help you become a great chemical engineer. You can also include any experiences that you have gained in this field after completing the undergraduate course. Remember that four important elements that a great personal statement includes such as the applicant’s motivation for seeking chemistry degree, his aspiration, work experience and qualities that relates to that field. While writing a personal statement keep one thing in mind that you need to put forth evidence of your skills and qualities that you claim to possess. You can use that outline to create the first draft. Do not edit the draft while writing because editing and revision can be done later. Do not worry about anything and just let your creativity do the work. Once the statement is completely written, revise it and see if it meets with the given word count requirement.

The My Lai Massacre of the Vietnam War

The My Lai Massacre of the Vietnam War On March 16, 1968, United States Army troops murdered several hundred Vietnamese civilians at the villages of My Lai and My Khe during the Vietnam War. The victims were mostly elderly men, women and children and all non-combatants. Many were also sexually assaulted, tortured or mutilated in one of the most horrifying atrocities of the entire bloody conflict. The official death toll, according to the US government, was 347, though the Vietnamese government asserts that 504 villagers were massacred. In either case, it took months for U.S. officials to catch wind of the actual events of that day, later filing court-martials against 14 officers present during the massacre yet only convicting the second lieutenant to four months in military prison. What Went Wrong at My Lai? The My Lai Massacre took place early in the Tet Offensive, a major push by the Communist Viet Cong  - National Front for the Liberation of South Vietnam  - forces to drive out the South Vietnamese government troops and the U.S. Army. In response, the U.S. Army initiated a program of attacking villages that were suspected of harboring or sympathizing with the Viet Cong. Their mandate was to burn houses, kill off livestock and spoil crops and pollute wells in order to deny food, water and shelter to the V.C. and their sympathizers. The 1st Battalion, 20th Infantry Regiment, 11th Brigade of the 23rd Infantry Division, Charlie Company, had suffered almost 30 attacks via booby-trap or land mine, resulting in numerous injuries and five deaths. When Charlie Company received its orders to clear out possible V.C. sympathizers in My Lai, Colonel Oran Henderson authorized his officers to go in there aggressively, close with the enemy and wipe them out for good. Whether the soldiers were ordered to kill women and children is a subject of dispute; certainly, they were authorized to kill suspects as well as combatants but by this point in the war Charlie Company evidently suspected all Vietnamese of collaborating - even 1-year-old babies. The Massacre at My Lai When the American troops entered My Lai, they did not find any Viet Cong soldiers or weapons. Nonetheless, the platoon led by Second Lieutenant William Calley began to fire at what they claimed was an enemy position. Soon, Charlie Company was shooting indiscriminately at any person or animal that moved. Villagers who tried to surrender were shot or bayoneted. A large group of people were herded to an irrigation ditch and mowed down with automatic weapons fire. Women were gang-raped, babies shot at point-blank range and some of the corpses had C Company carved into them with bayonets. Reportedly, when one soldier refused to kill the innocents, Lt. Calley took his weapon away and used it to massacre a group of 70 to 80 villagers. After the initial slaughter, the 3rd Platoon went out to conduct a mop-up operation, which meant killing any of the victims who were still moving amongst the piles of dead. The villages were then burned to the ground. The Aftermath of My Lai: Initial reports of the so-called battle at My Lai claimed that 128 Viet Cong and 22 civilians were killed -   General Westmoreland  even congratulated Charlie Company for their work and the Stars and Stripes magazine lauded the attack. Several months later, though, soldiers who had been present at My Lai but refused to take part in the massacre began to blow the whistle on the true nature and scale of the atrocity. Privates Tom Glen and Ron Ridenhour sent letters to their commanding officers, the State Department, the Joint Chiefs of Staff, and President Nixon exposing Charlie Companys deeds. In November of 1969, the news media got wind of the My Lai story. Journalist Seymour Hersh conducted extensive interviews with Lt. Calley, and the American public responded with revulsion to the details as they slowly filtered out. In November of 1970, the US Army began court-martial proceedings against 14 officers charged with participating in or covering up the My Lai Massacre. In the end, only Lt. William Calley was convicted and sentenced to life in prison for premeditated murder. Calley would serve only four and a half months in military prison, however. The My Lai Massacre is a chilling reminder of what can happen when soldiers cease to regard their opponents as human. It is one of the worst known atrocities of the war in Vietnam.
