Analog and Digital

Analog and digital are the terms that we often referred with data and signals. In today’s discussion we will be talking about both analog and digital data, and analog and digital signals. If we say that there is a sender who has some data to be transmitted to the receiver. But the data that is […]

Geostationary Satellite

A geostationary satellite is one of the communication satellites that creates the communication channel between the sender and receiver present at different locations on the earth. This satellite appears stationary as if it is fixed in the sky. Geostationary Satellite Definition A geostationary satellite is a satellite that appears stationary when we observe them from […]

Flow Control in Data Link Layer

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 […]

Performance of a Network

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)

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

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

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

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 […]

Types of Addressing in Network

Addressing in 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 that you want to send some parcel to your friend living in a different […]

Point to Point WAN

Point to Point WAN is a kind of network where two end devices are connected using a public network, for example, telephone network. In this article, we will discuss some devices that we use to establish a point to point wide area network. Point to Point WAN Modems DSL Technology Cable Modem T Lines SONET […]
