Types of Computer Networks

Types of computer networks - What do you think after grunt the computer network? There must be thinking that the computer network is a network that connects 2 or more computer devices to exchange information or communicate.
Types of Computer Networks

Computer networks may already be familiar to us because it is going on almost every day we involve a computer network in the work or daily life.

For those of you who do not know what is a computer network, we can see the full review of the Definition of computer networks below.

Definition of Computer Networks

A computer network is a network system consisting of two more computers that are connected that form a computer network through the media transmission or communication media, so it can be various information, data, applications, and various the Internet.

This computer network itself can also be interpreted as a collection of some communication terminals consisting of two or more interconnected computers in a network.

The purpose of the computer network is for the information or data under which the transmitter can be received properly to the receiver.

Okay do not have much base stale, direct this time Laptopsiipat will discuss what kind of computer network type, more see here Yes.

Types of computer networks

In general, computer networks can be grouped into 4 categories, based on geographic, distribution of information or data sources, data transmission media, the role and relationship of each computer in processing data.

A. Various computer networks based on the geographical reach

Various computer networks based on the geographical reach

1. LAN

LAN stands for Local Area Network is a network that covers only a small area, such as in an Internet cafe, office, or school.

Generally, the area's wide LAN network is not far from 1 square km. Normally, the LAN network uses IEEE 802.3 Ethernet which has data transfer speeds of about 10 to 1000 MB/s.

The distance to the LAN is 5-10 km.

In addition to using Ethernet technology, many also use wireless technologies such as Wi-fi for LAN networks

2. MAN

The MAN or extension of the Metropolitan Area Network is a network that includes a city with a high data transfer rate.

Arguably, this MAN network is a composite of several LAN networks. The range of this MAN is 10-50 km.

MAN has only one or two cables and is not equipped with switching elements that serve to make a draft more simple.

3. WAN

The WAN or the extension of the Wide Area Network is a wide-range network that covers a wide geographic area, such as between countries and even continents.

WAN is generally used to connect two or more local networks to make it easier to communicate with other users even in different locations.

For the distance, the WAN can be up to 100 km – 1000 km.

B. Kinds of computers based on the distribution of information sources/Data

Kinds of computers based on the distribution of information sources/Data

1. Centralized Network

This is a centralized network that consists of a client computer and a server computer where the client's computer serves as an intermediary in accessing the source of information or data originating from the server computer.

In a centralized network, there is a dumb terminal or the term silent terminal, where the terminal does not have any data processing tools.

2. Distributed Network

This network is the combined result of several centralized networks that allow multiple server and client computers to be interconnected and form a network system.

C. Kinds of computer networks based on Media Data transmission

Kinds of computer networks based on Media Data transmission

1. Wireless network

In this network, no cable is required because this network is cordless but in this network, it is necessary electromagnetic waves as its data transmission media.

Unlike a wired network, this network does not use cables to exchange information/data with other computers but instead uses electromagnetic waves to transmit the data information signal between computers one with other computers. A wireless adapter is one of the transmission media used in a wireless network.

2. Wired Network

The data transmission Media used in this network is a cable. The cable is used to connect one computer to another computer to exchange information or data connection on the Internet. One of the admissions used in the Wired network is UTP cable.

D. Various computer networks based on the role and relationship of each computer in processing Data

Various computer networks based on the role and relationship of each computer in processing Data

1. Network Client Server

This network consists of one or more client computers, usually consisting of a single server computer and several client computers.

A server computer task is to provide data resources that will be later used by the Client computer. While the client computer has a task that uses data resources that have been provided by the server computer.

2. Peer to Peer Network

In this network each computer is either a server computer or a client computer that has the same position, so the server computer can be a client computer, and vice versa the client computer can also be a server computer.

This network requires only 2 computers and 1 cable to be connected in the network.

Well, that's an explanation of sorts of computer networks.
Hopefully with this article can be useful to you especially those who want to know more about the type of computer network type.
