Computer networking is all about sharing with others — just like kindergarten. But rather than share crayons or toys, you use a computer network to share. A computer network, or data network, is a digital telecommunications network which allows nodes to share resources.

What is the Computer Name? Every operating system asks you to give a computer name when you install it on a PC or device. Windows is pc networking exception to this rule. In order to successfully join a workgroup and use all the available network pc networking features, your computer must have a unique computer name.

This name should have a maximum of 15 characters and should not include spaces or special characters like: What is the IP Address?

What is a Computer Network? - Definition from Techopedia

When pc networking connect to a network, you will always receive an IP address. This concept is similar to the computer name in the sense that it is used to identify your PC or device pc networking the network and provide a unique address where other computers or devices can find it.

IP addresses are binary numbers but they are displayed in human-readable notations, such as In a home network, the IP addresses are automatically given to every device or PC by the router, when the network connection is established. There are several ways to learn the IP address of your computer.

A list is displayed with pc networking your network adapters and their properties.


There you will see the IP address pc networking have for your active network connection. The signal pc networking retransmitted at a higher power level, or to the other side of an obstruction, so that the signal can cover longer distances without degradation.

In most twisted pair Ethernet configurations, repeaters are required for cable that runs longer than meters. With fiber optics, repeaters can be tens or even hundreds of kilometers apart.

A repeater with multiple ports is known as pc networking Ethernet hub. Repeaters work on the physical layer of the OSI model. Repeaters require a small amount of time to regenerate the signal. This can cause a propagation delay that affects network performance and pc networking affect proper function.

As a result, many network architectures limit the number of repeaters that can be used in a row, e.

Hubs and repeaters in LANs have been mostly obsoleted by modern switches. Bridges[ edit ] A network bridge pc networking and filters traffic between two network segments at the data link layer layer 2 of the OSI model to form a pc networking network.


This breaks the network's collision domain but maintains a unified broadcast domain. Network segmentation breaks down a large, congested network into an aggregation of smaller, more efficient networks.

Bridges come in three basic types: Directly connect LANs Remote bridges: Remote bridges, pc networking the connecting link is slower than the end networks, largely have been replaced with routers. pc networking

Switches[ edit ] A network switch is a device that forwards and filters OSI layer 2 pc networking frames between ports based on the destination MAC address in each frame. It can be thought of as pc networking multi-port bridge.

If an unknown destination is targeted, the switch broadcasts to pc networking ports but the source. Switches normally have numerous ports, facilitating a star topology for devices, and cascading additional switches.
