Error Correction in Computer Networks

In this tutorial, we are going to learn about error correction in computer networks. When data goes from the sender to the receiver, error correction codes are there to detect and correct problems. Methods of Error Correction in Computer Networks: There are two methods for correcting errors: Backward error correction: When a backward mistake is… Continue Reading »

Error Detection in Computer Networks

Here, we will learn about error detection in computer networks. When data goes from one device to another, the system cannot guarantee that the data received by one device matches the data sent by the other. An error occurs when the message received at the receiver end varies from the message sent. A mismatch occurs… Continue Reading »

Multiplexing in Computer Networks

In this tutorial, we will know about Multiplexing in computer networks. Multiplexing is a method of both combining and transmitting numerous data streams over a single channel. Multiplexing is accomplished using a device known as a Multiplexer (MUX). It combines n input lines into a single output line. Many-to-one multiplexing means there are n input… Continue Reading »

Application Layer in OSI Model in Computer Networks

In this tutorial, we are going to learn about application layer in OSI model. In the OSI model, the application layer is the layer closest to the end user, which implies both the application layer and the end user can interact directly with the software application. Both client and server programs make up the application… Continue Reading »

Transport Layer in OSI Model in Computer Networks

In this tutorial, we will learn about transport layer in OSI model. The fourth layer from the top is the transport layer. It’s primary function is to provide direct communication services to application processes running on various hosts. This layer allows application processes running on separate hosts to communicate logically. Despite the fact that application… Continue Reading »

Network Layer in OSI Model in Computer Networks

In this tutorial, we are going to learn about network layer in OSI model. The network layer (Layer 3) is in charge of delivering data packets from their source to their destination through numerous hops (nodes). It’s in charge of the subnet’s operations. The Network Layer in OSI Model converts the logical addresses to physical… Continue Reading »

Data Link Layer in OSI Model in Computer Networks

In this tutorial, we are going to learn about data link layer in OSI.  The data link layer is the second layer from the bottom in the OSI model. This layer is one of the most difficult to understand, with several functionalities and risks. The data connection layer hides the underlying hardware features and represents… Continue Reading »

Physical Layer in OSI Model in Computer Networks

The Physical Layer in the OSI Model, which is a physical and electrical representation of the system, is the lowest layer. It has various network components such as power plugs, connectors, receivers, and different cable kinds. This layer transports data bits from one device (such as a computer) to another (s). The types of encoding… Continue Reading »

Computer Network Models

Here, we are going to know about computer network models. Before that I would like to suggest you to go through the previous post. There are mainly two types of models, e.g. OSI model and TCP/IP model. OSI Network Models : The International Organization for Standardization (ISO) developed the OSI model in 1984. We now… Continue Reading »

Basics of Computer Networking

In this tutorial, we will know the basics of computer networking. Computer Networking: Multiple devices, also known as hosts, that are connected via multiple channels for the purpose of sending and receiving data or media. Computer networks can also comprise a variety of devices or mediums that help two or more machines communicate; these are… Continue Reading »
