Connection of at least two computer systems
- In information technology, a network is defined as the connection of at least two computer systems, either by a cable or a wireless connection. The simplest network is a combination of two computers connected by a cable. This type of network is called a peer-to-peer network.

A computer network is a system that connects many independent computers to share information (data) and resources. The integration of computers and other different devices allows users to communicate more easily. A computer network is a collection of two or more computer systems that are linked together. A network connection can be established usin...
Computer Networks are one of the important aspects of Computer Science. In the early days, it is used for data transmission ontelephone linesand had a very limited use, but nowadays, it is used in a variety of places. Computer Networks help in providing better connectivity that helps nowadays. Modern computer networks have the following functionali...
In simple terms, a computer network is made up of two main parts: devices (called nodes) and connections (called links). The links connect the devices to each other. The rules for how these connections send information are called communication protocols. The starting and ending points of these communications are often called ports.
Computer Networks simply work using nodes and links. Data communication equipment is simply termed as Nodes. For example, Modems, Hubs, Switches, etc. whereas links in Computer networks can be referred to as a connection between two nodes. We have several types of links like cable wires, optical fibers, etc. Whenever a Computer Network is working, ...
Performance: It can be measured in many ways, including transmit time and response time. Transit time is the amount of time required for a message to travel from one device to another. Response tim...Reliability: In addition to accuracy is measured by frequency of failure, the time it takes a link to recover from failure, and the network’s robustness in catastrophe.Security:Network security issues include protecting data from unauthorized access, protecting data from damage and development, and implementing policies and procedures for recovery from breaches a...Programs do not have to execute on a single system because of resource and load sharingReduced costs – Multiple machines can share printers, tape drives, and other peripheralsReliability – If one machine fails, another can take its placeScalability (it’s simple to add more processors or computers)Division Based on Area Covered
1. Local Area Network (LAN):A LANis a network that covers an area of around 10 kilometers. For example, a college network or an office network. Depending upon the needs of the organization, a LAN can be a single office, building, or Campus. We can have two PCs and one printer in-home office or it can extend throughout the company and include audio and video devices. Each host in LAN has an identifier, an address that defines hosts in LAN. A packet sent by the host to another host carries both...

1. Point To Point networks:Point-to-Point networkingis a type of data networking that establishes a direct link between two networking nodes. A direct link between two devices, such as a computer and a printer, is known as a point-to-point connection. 2. Multipoint: is the one in which more than two specific devices share links. In the multipoint environment, the capacity of the channel is shared, either spatially or temporally. If several devices can use the link simultaneously, it is a spat...

1. P2P Networks: Computers with similar capabilities and configurations are referred to as peers. The “peers” in apeer-to-peernetwork are computer systems that are connected to each other over the Internet. Without the use of a central server, files can be shared directly between systems on the network. 2. Client-Server Networks: Each computer or process on the network is either a client or a server in a client-server architecture (client/server). The client asks for services from the server,...
Computer Network Architecture is of two types. These types are mentioned below. 1. Client-Server Architecture: Client-Server Architectureis basically the architecture where the clients and the server are connected as two clients can communicate with each other and the devices present work as servers in the network. 2. Peer-to-Peer Architecture: Pee...
There are three main types of Enterprise Computer Networks which are mentioned below. 1.

No industry—whether it’s education, retail, finance, tech, government, or healthcare—can function without well-designed computer networks. The larger the organization, the more complex the network becomes. Before starting the challenging job of creating and setting up a computer network, here are some key objectives to consider.
