Networking Topologies and TCP/IP protocol Bus Topology It just doesn’t get much simpler than the physical bus topology when it comes to connecting nodes on a Local Area Network (LAN). The most common implementation of a linear bus topology is IEEE 802.3 Ethernet. All devices in a bus topology are connected to a single cable called the bus‚ backbone‚ or ether. The transmission medium has a physical beginning and an end. All connections must be terminated with a resistor to keep data transmissions

Internet Protocol Suite is the set of communications protocols used for the Internet and other similar networks. It is commonly also known as TCP/IP named from two of the most important protocols in it: the Transmission Control Protocol (TCP) and the Internet Protocol (IP)‚ which were the first two networking protocols defined in this standard. Modern IP networking represents a synthesis of several developments that began to evolve in the 1960s and 1970s‚ namely the Internet and local area networks‚ which

2008) In 1973‚ a paper titled "A Partial Specification of an International Transmission Protocol" was written by Vint Cerf. This paper included a system for more efficiently transmitting information across a network and also included references to TCP or transmission control protocol. In 1973‚ Robert Kahn (open network architect for the United States defense advanced research projects agency) enlisted the help of Vinton Cerf and together they created an in-depth document outlining the transmission

Internet daemon) is started in my system rather than inetd (internet service daemon). Both of them are super-server daemon started only under request. Because xinetd is more secure than inetd‚ more Unix- services now replace inetd with xinetd. Exercise 4 Q:Compare the file ser_more and ser_cp. Are these two files identical? A:Yes‚ they are identical. Q:Display the file sizes using ls –l ser*. Save the output. What are the sizes of files A: ser_more‚ ser_cp‚ and ser_cat? ser_cat 39870 bytes

in TCP/IP At first glance‚ TCP/IP (Transmission Control Protocol/Internet Protocol) may seem baffling. Many other protocols‚ such as NetBEUI and IPX/SPX‚ require no configuration. TCP/IP is different. Due to the seemingly endless number of options that you can configure within TCP/IP‚ many people become intimidated at first. In reality‚ however‚ TCP/IP isn ’t very difficult‚ but you have to gain some understanding of what you ’re configuring. So‚ I ’m going to give you a crash course in TCP/IP.

TCP/IP Analyze the current options available for use of TCP/IP and OSI models for businesses. The 5-layer model serves essentially the protocols regarded as Transmission Control Protocol (TCP) as well as Internet Protocol (IP)‚ or mutually‚ TCP/IP. The User Datagram Protocol (UDP) is likewise served by this particular model. The 5-layer model was produced alongside with these protocols‚ anteceding the 7-layer model‚ and is from time to time known as the TCP Model. Layer Name
