Types, Networking

TYPES OF NETWORKING

Generally, a computer network can be classified into five categories, based on geographical reach, distribution of sources of information / data, data transmission media, the role and relationship of each computer in processing the data, and based on the type of topology is used. Here's the full translation:

BY GEOGRAPHIC SCOPE

1. LAN

Local Area Network or LAN is often abbreviated with a network that covers only a small area, such as cafes, offices, or schools. Generally the LAN network, the area is not far from 1 km square.

Usually LAN network using the IEEE 802.3 Ethernet technologies that have a data transfer rate of about 10, 100, or even 1000 MB / s.

In addition to using Ethernet technology, not a few also are using wireless technologies such as Wi-Fi to the LAN network.

2. MAN

Metropolitan Area Network or MAN is a network that includes a city and comes with high speed data transfer. Arguably, MAN network is a combination of several LAN networks.

Narrows reach of the network MAN range of 10-50 km. MAN has only one or two wires and is not equipped with a switching element which serves to make the design becomes more simple.

3. WAN

Wide Area Network or WAN is a network whose reach covers a wide geographical area, such as a country or even continent.

WAN is generally used to connect two or more local networks so that users can communicate with other users despite being in a location that berbebeda.

DISTRIBUTION BY SOURCE OF INFORMATION / DATA

1. Centralized Network

The definition of a centralized network is a network that consists of a client computer and the server computer where the client computer serving as an intermediary in accessing sources of information / data coming from the server computer.

In a centralized network, there is the term dumb terminal (dumb terminal), where the terminal does not have the data processing devices.

2. Distributed Networks

This network is the result of the combination of several centralized network that allows multiple servers and client computers that are connected to form a particular network system.

DATA TRANSMISSION BASED MEDIA USED

1. Wired Network (Wired Network)

Data transmission medium used in this network either wired.

The cables are used to connect one computer to another computer in order to exchange information / data or connect to the Internet.

One of the transmission medium used in a wired network is a UTP cable.

2. Wireless Network (Wireless Network)

In this network required electromagnetic waves as transmission media data.

Unlike the wired network (wired network), this network does not use a cable to exchange information / data with other computers it uses electromagnetic waves to transmit information signals / data between one computer to another computer.

Wireless adapter, one of the transmission medium used in the wireless network.

ROLE AND RELATIONSHIP BASED ON EACH COMPUTER IN THE DATA PROCESSING

1. Client-Server Network

This network consists of one or more computer servers and client computers. Usually consists of one server computer and multiple client computers.

The server computer is responsible for providing data resources, while the client computer can only use the data resources.

2. Peer to Peer

In this network, each computer, be it a computer server or the client computer has the same position.

Thus, the server computer can be a client computer, and vice versa client computer can also be a computer server.
