In today's article, we at Campusify are going to provide you with important notes that will be very beneficial in your studies. We guarantee that by using these notes, you will definitely benefit from them in your MSBTE exam.

Data Communication And Computer Network Notes Overview

The notes provided by Campusify are given by Topper, so there is no doubt that they are important or not. In terms of Engineering, DCN is a very important subject and is not easy at all, but you can pass this subject very easily using these notes.

Important Points In Data Communication And Computer Network 

Reliable Versus Unreliable
The transport layer service can be reliable or unreliable. If the application layerprogram needs reliability, we use a reliable transport layer protocol by implementing flow and error control at the transport layer. This means a slower and more complex service. On the other hand, if the application program does not need reliability because it uses its own flow and error control mechanism or it needs fast service or the nature of the service does not demand flow and error control (real-time applications), then an unreliable protocol can be used.

RARP

Reverse Address Resolution Protocol (RARP) finds the logical address for a machine that knows only its physical address. Each host or router is assigned one or more logical(IP) addresses, which are unique and independent of the physical (hardware) address of the machine. To create an IP datagram, a host or a router needs to know its own IP address or addresses. The IP address of a machine is usually read from its configuration file stored on a disk file.
However, a diskless machine is usually booted from ROM, which has minimum booting information. The ROM is installed by the manufacturer. It cannot include the IP address because the IP addresses on a network are assigned by the network administrator. The machine can get its physical address (by reading its NIC, for example), which is unique locally. It can then use the physical address to get the logical address by using the RARP protocol. A RARP request is created and broadcast on the local network. Another machine on the local network that knows all the IP addresses will respond with a RARP reply.
The requesting machine must be running a RARP client program; the responding machine mustbe running a RARP server program. There is a serious problem with RARP: Broadcasting is done at the data link layer. The physical broadcast address, allis in the case of Ethernet, does not pass the boundaries of a network. This means that if an administrator has several networks or several subnets, it needs to assign a RARP server for each network or subnet. This is the reason that RARP is almost obsolete. Two protocols, BOOTP and DHCP, are replacing RARP.

Translation Bridge

A translation bridge, illustrated in Figure 4.15, is a data-link layer device that connects network segments using different network media or different protocols. This bridge is more complicated than a local bridge because, in addition to reading the headers in the packet, the bridge strips the data-link layer frame off the packets to be relayed to other network segments and packages them in a new frame for transmission on the other segment.
The bridge can thus connect an Ethernet segment to a Fiber Distributed Data Interface (FDDI) segment or connect two different types of Ethernet segments (such as 100Base-TX and 100Base-T4) while retaining a single broadcast domain. Because of the additional packet manipulations, translation bridging is slower than local bridging, and translation bridges are more expensive as well. Because there are other types of devices that can connect different network types, such as routers, the use of translation bridges is relatively rare.
