Computer Network Terms

A computer network is the interconnection of computers to transmit information between them according to certain rules or protocols. It is very important to know about common terms like Router, Switch, Firewall, Hub etc. used in computer networks. For computer problems, use a reliable impcsupport computer service.

A computer network is an interconnection of computers to share information according to some defined rules or protocols. This data is transmitted via the OSI (open system interconnection) model. In this process one device is capable of sending / receiving data to / from at least one process that is on a remote device, then both devices are said to be in the network. A network is a group of devices that are connected to each other. Networks can be classified into various characteristics, such as the media used to transport data, the communication protocols used, scale, topology, benefits, and organizational scope. In this article I will make you aware of some of the common terms used in the networking field:

Computer Networks: A computer network is the interconnection of computers for sending information between computers via communication channels. It can also be classified by information flow such as half duplex and full duplex.

 Network Topology:

Network topology is a geographic representation of the network. In general, computer networks are technically classified based on the total network topology which includes the network structure as well. They are divided into Bus network, Ring network, Star network, Mesh network, Star-bus network, Tree network, Hybrid network.

Router:

A router is a device designed to forward the data packets it receives, to the next available or neighboring one between networks.

Switch:

A switch is a virtual controller for routers and bridges. These flow control switches are operated from each of the individual layers of the OSI layer. Certain cases where a device operates on several layers are called multilayer switches.

Bridges:

Technically, a bridge acts as a connector between the data link layer and the network layer. The three types of bridges are local bridges, remote bridges and wireless bridges. Bridges come in three basic types:

1. Local bridge

Directly connect LAN

2. Long distance bridges

Can be used to create a wide area network (WAN) connection between LANs. Long-distance bridges, where the connecting link is slower than the end network, have been largely replaced by routers.

3. Wireless bridge

Can be used to join a LAN or connect a remote station to a LAN.

Network card

The network card is the most important hardware component of the network. The most important layer functionality is to enable communication between computers in a network.

Firewall

A firewall is an important aspect of a network with respect to security. Usually denies access requests from insecure sources while allowing actions from recognized ones. The vital role firewalls play in network security is growing in parallel with the constant increase in ‘cyber’ attacks for the purpose of stealing / corrupting data, planting viruses, etc.

Repeater

A repeater is an electronic device that receives a signal, clears it of unnecessary noise, regenerates it, and sends it back at a higher power level, or to the other side of the barrier, so the signal can travel longer distances without degradation. In most twisted pair Ethernet configurations, a repeater is required for cables running more than 100 meters.

Hub

Repeaters with multiple ports are known as hubs.

Repeaters work on the Physical Layer of the OSI model. The repeater takes a little time to regenerate the signal. This can cause propagation delays that can affect network communication when there are multiple repeaters in a row. Many network architectures limit the number of repeaters that can be used consecutively.
