The development of ICT continues to increase along with the increasing human needs. Currently the trend of the use of computer networks has been widely used in various types ranging from small businesses (such as internet cafes,) and government agencies (schools, campuses, etc.) and so forth. Information and Communication Technology seems to have ingrained in every human being in this era, Information and Communication Technology that has become globally able to cover all aspects of life (Information according into Technology and Informatics Journals).

Computer Network Topology - Definition, Bus, Ring, Star, Media, Linear, Type, Installation, Component: Information and Communication Technology (ICT) is currently highly developed in society. Due to the rampant use of Information Technology today, there needs to be knowledge about the application of computer networks in everyday life. In other words, to prevent misunderstanding about information technology that results in the misuse of the main functions of information technology. Generally information technology is a technology used to manage data, including in it: compiling, storing, manipulating data processing, obtaining, in various ways and procedures to produce quality information and high-value use (Submitting Journal Paper).

Based on data transmission media

Based on the transmission media computer network can be divided into 2 types, namely:

Wired Network

In this network, to connect one computer with another computer is needed as a network cable connector. Network cable functions in sending information in the form of electrical signals between network computers.

Wireless Network

Is a network with a medium in the form of electromagnetic waves. In this network cable is not needed to connect between computers because it uses electromagnetic waves that will send information signals between network computers.

Basic Introduction to Computer Networks

Based on the distribution of information / data sources.

Based on the distribution of information / data sources, computer networks are divided into 2 types, namely:

Centralized Network.

This network consists of client computers and servers where client computers function as intermediaries to access information / data sources that originate from one server computer.

Distributed network.

Is a combination of several centralized networks so that there are several computer servers that are interconnected with clients to form a particular network system.

Based on geographical reach.

Based on the geographical reach of computer networks can be divided into 3 types, namely:

LAN network.

is a network that connects 2 or more computers in scope such as laboratories, offices, and in 1 internet cafe.

MAN Network

It is a network that covers one big city and its local area. For example local telephone networks, cellular telephone systems, and relay networks of several internet ISPs.

WAN network

Is a network with worldwide coverage. For example the network of PT. Telkom, PT. Indosat, as well as GSM Cellular networks such as Satelindo, Telkomsel, and many more.

Based on the role and relationship of each computer in processing data.

Based on the role and relationship of each computer in processing computer network data can be divided into 2 types, namely:

Client-Server Network

On this network there are 1 or several server computers and client computers. The computer will be a server computer or a client computer and is changed through network software in the protocol. The client computer as an intermediary to be able to access data on the server computer while the server computer provides information needed by the client computer.

Peer-to-peer network

On this network there are no client computers or server computers because all computers can send and receive information so that all computers function as clients as well as servers.
