Chapter Seven| Review Questions Q1- What is Internet? Who used it and why ? A Collect of interconnected networks‚ all freely exchanging information. More than 1.3 billion people use the internet around the world‚ the internet make the life easier and faster at all things. Q2-What is the ARPANET ? A project started by the U.S. department of Defense (DoD) in 1969 as both an experiment in reliable networking and a means to link DoD and military research contractors including many universities

Routers are Computers A router is a computer‚ just like any other computer including a PC. The very first router‚ used for the Advanced Research Projects Agency Network (ARPANET)‚ was the Interface Message Processor (IMP). The IMP was a Honeywell 316 minicomputer; this computer brought the ARPANET to life on August 30‚ 1969. Note: The ARPANET was developed by Advanced Research Projects Agency (ARPA) of the United States Department of Defense. The ARPANET was the world’s first operational packet

Introduction They are numerous protocols and standards that are used for communications over networks. But only a few protocols are cryptographic in nature. Cryptographic protocols provide secure communication between two communicating entities over the insecure network. Cryptographic protocols use either symmetric or asymmetric or a combination of both the algorithm to secure the communication channel. Presented in this paper are various cryptographic protocols that provide encryption to data in

a. Flow control It is the process of managing the rate of data transmission between two nodes to prevent a fast sender from outrunning a slow receiver. It provides a mechanism for the receiver to control the transmission speed‚ so that the receiving node is not overwhelmed with data from transmitting node. Flow control should be distinguished from congestion control‚ which is used for controlling the flow of data when congestion has actually occurred. Error control It is the process of detecting

Logical and Physical Network Design Logical and Physical Network Design Network design is a process that begins from the first thought on how to connect to computers together in order for them to communicate and pass needed data to each other. The process may seem simple on this level and may require little consideration‚ but in fact‚ there are many areas of the network that need to be examined before the process of networking should be undertaken. For the small network‚ these considerations

A protocol is a standard method or format for communication between network devices. Protocols ensure that data are transferred whole‚ in sequence‚ and without error from one node on the network to
