Computer Networks

Flow control in the data link layer is a technique that controls the rate of data transmission between the sender and receiver. If the sender is on a fast and powerful computer as compared to the receiver then the receiver may get overwhelmed by the frames transmitted by the sender. In such a scenario even […]

The performance of a network is an important issue in every network. To determine the performance of a network there are various parameters such as how efficient a network is, is the network reliable, the speed of data transmission, is the network secure, etc. Here we will discuss the terms which are used to decide […]

Address Resolution Protocol (ARP) is the dynamic address mapping protocol that is used to identify the physical address (MAC address) of the device whose logical address is known. ARP is a network layer protocol. Address Resolution Protocol (ARP) Requirement of ARP Functioning of ARP Packet Format Requirement of ARP We know that when a sender […]

Data transmission is the transfer of analog or digital data between two devices. Data transmission enables the two devices to communicate with each other. In this section, we focus on digital data transmission. Digital data transmission is the transmission of bits between the two I/O devices or the components of the computer. To set up […]

Guided transmission media involves the physical medium for the transmission of information from one place to another. The physical medium guides the information bits and directs them to the path they have to travel in order to reach the desired destination. Types of Guided Transmission Media 1. Magnetic Media This is the oldest and most […]

Transmission impairment is the damage or harm caused to the signal during the signal transmission. Due to the transmission impairment, the signal received at the receiver end may differ from the signal sent by the sender. This difference in the strength of the signal is signal impairment. Now the question what is the reason behind […]

What is Addressing in Networking? Addressing in the network lets the two remote nodes in the network to communicate with each other. The communicating system in the network using TCP/IP protocols use four types of addressing, one at each layer of TCP/IP architecture. Consider the real-world situation in that you want to send a parcel […]

What is Point-to-Point WAN? Point-to-Point WAN is a kind of computer network where two end devices are connected using a public network. For example, a telephone network. In this content, we will discuss some devices that we use to establish a point-to-point wide area network. Table of Contents Modems DSL Technology Cable Modem T Lines […]
