Internet in Networking

The Internet in networking is nothing but a network of networks. Networks of different sizes, shapes and forms are connected together to form a big network that we refer to as the Internet. It is a structured and well-organized system that allows communication between connected devices. Let us explore the Internet to know more about […]

Routers and its Types

Routers are the devices that are essential in networking. They play a vital role in directing the best path to the packet to reach the final destination. The router is a three-layer device. Routers in Computer Network What is Router? Working of Router Types of Routers Advantages and Disadvantages What is Router? A router is […]

Modem and its Types

The modem and its types are the networking device that is essential in connecting your computer to the internet. The modem is responsible for modulating and demodulating the signal between your telephone line and your computer. Thus, the modem is a short form of modulation and demodulation. The telephone network transmits data using analog signals. […]

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 […]
