- Arpanet - 652 words
ARPANET The USSR launches Sputnik, the first artificial earth satellite. In the late 1960s the U.S. military was desperately afraid of a nuclear attack from the Soviet Union. The United States formed the Advanced Research Projects Agency (ARPA) within the Department of Defense to establish a bombproof network to connect military bases. ARPANETs physical network was established in 1969 to enable universities and research organizations to exchange information freely. The first two nodes that formed the ARPANET were UCLA and the Stanford Research Institute, shortly after the University of Utah was added to ARPANET. The Network Control Protocol (NCP) was initially used as the ARPANET protocol, b ...

- Asynchronous Transfer Mode - 1,094 words
Asynchronous Transfer Mode Asynchronous Transfer Mode: Asynchronous Transfer Mode By Gene Bandy State Technical Institute Asynchronous Transfer Mode: Asynchronous Transfer Mode(ATM) is a high-speed transmission protocol in which data blocks are broken into small cells that are transmitted individually and possibly via different routes in a manner similar to packet-switching technology. In other words, it is a form of data transmission that allows voice, video and data to be sent along the same network. In the past, voice, video and data were transferred using separate networks: voice traffic over the phone, video over cable networks and data over an internetwork. ATM is a cell- switching and ...

Father Of Internet Technology Evaluation of Craig Brockman's Assignment by Eric Becker (05/22 05:40 PM) Grade: A Craig H. Brockman Instructor: Eric Becker College Writing 9 May 2000 Dr. Leonard Kleinrock: Father of Internet Technology Most every work of human progress has carried within it the signature of one or more individuals who saw beyond the horizon, challenged convention and then, in ways large and small, forever changed our world. Some of these signatures, like Alexander Graham Bell, who invented the telephone and Thomas Edison, whose many patents include both the electric light bulb, the microphone and record player, are easily identifiable. But what about a work of human progress ...

- Frame Relay - 1,641 words
Frame Relay Frame Relay and Leased Lines In networking there are many options in having data transferred from one location to another. Two of which include frame relay and leased lines. Frame relay is a communication method that transfers data by dividing information into packets and sending them over a virtual network. Frame relay is a difficult process to understand and to accomplish. Leased lines, however, is the permanent connection between two stations. Leased lines are simpler to understand and do not take a lot of effort to achieve. According to Computer Networks, frame relay came into existence to overcome the complex protocols caused by slow telephone lines, and expensive computers. ...

- History Of The Internet - 629 words
History Of The Internet History of the Internet The Internet as we know today was not a concept that was quickly enacted when it was first thought up. It was a revolutionary process that was the result of visionary people who painstakingly brought forth the World Wide Web. These individuals saw a promising potential in allowing computers to share information on research and development in scientific and military fields. This is all started in 1962 when the U.S. Defense Advanced Research Projects Agency (DARPA) initiated a research program. They selected J.C.R. Licklider of MIT to head the work and develop it. Later Leonard Kleinrock of UCLA who developed the theory of packet switching, which ...

- How Ethernet Works - 2,076 words
... well, errors can still occur. A burst of electrical noise may occur somewhere in a cabling system, for example, corrupting the data in a frame and causing it to be dropped. Or a LAN channel may become overloaded for some period of time, which in the case of Ethernet can cause 16 collisions to occur on a transmission attempt, leading to a dropped frame. No matter what technology is used, no LAN system is perfect, which is why higher protocol layers of network software are designed to recover from errors. It is up to the high-level protocol that is sending data over the network to make sure that the data is correctly received at the destination computer. High-level network protocols can do ...

- Internet History - 1,118 words
Internet History In 1973, the U.S. Defense Advanced Research Projects Agency (DARPA) initiated a research program to investigate techniques and technologies for interlinking packet networks of various kinds. The objective was to develop communication protocols which would allow networked computers to communicate transparently across multiple, linked packet networks. This was called the Internetting project and the system of networks which emerged from the research was known as the "Internet." The system of protocols which was developed over the course of this research effort became known as the TCP/IP Protocol Suite, after the two initial protocols developed: Transmission Control Protocol (T ...

- Internet History - 1,295 words
Internet History Starting out as a small military experiment some 35 years ago, the Internet is quickly becoming one of the most popular forms of communication. With a present population of about 40 million users world wide, it seems to have a very promising future. Uncensored and almost impossible to monitor, it's a breeding ground for all sorts of offensive and derogatory information. On the other hand, it is probably the biggest single source of data in the world brought home into your personal computer. Will this form of communication survive in the future, or will it simply die out like many others have in the past? History The first nodes of the Internet were built 36 years ago by the ...

- Internet History Report - 948 words
Internet History Report The Internet was created in 1969 by scientists working for ARPA. ARPA stands for advanced research projects agency, and was formed to create a network of computers that could save information in the event of a nuclear attack. UCLA, Stanford Research Institute (SRI), UC Santa Barbara (UCSB), and the University of Utah in Salt Lake City were the first ARPANET locations. The ARPANET is what is now called the Internet. The plan was unprecedented: A professor at UCLA, and his small group of graduate students hoped to log onto the Stanford computer and try to send it some data. They would start by typing login, and asking by telephone if the letters appeared on the far-off ...

- The Evolution - 600 words
The Evolution In nature evolution occurs throughout various different things. Also evolution occurs in technology. Take for instance, ATM was an evolution of frame relay, and frame relay was an evolution of packet switching. Evolution happens everywhere but in technology it happens all the time. Packet switching technology breaks down messages into fixed-length pieces called packets and sent through a network individually. In packet switching messages are segmented into packets of a pre determined size before they are sent. This process is called packetizing. The packets are normally 1000 bytes long. There is a lot of error protection in the packet. Packet switching networks are made to run ...

- Wireless Technology - 2,058 words
... ss, you would have to use the same brand of network interface card throughout your network. Right now you are, for the most part, tied to whichever brand of wireless LAN you pick. Most of the products in this comparison listed their wireless protocol as Ethernet carrier sense multiple access/collision avoidance (CSMA/CA), a variation of standard Ethernet. Unfortunately, each vendor has put its own spin on CSMA/CA, which means even their protocols are incompatible. 5 Wireless services As technology progresses toward smaller, lighter, faster, lower power hardware components, more computers will become more and more mobile. For space concerns this paper will exclude any further discussion o ...
