Network ???

Assalamualaikum...

This is my third post and I will share about network. Network basic is one of topic in computer science that I learned in this second semester. To be exactly, my first topic. 

First,I'm going to share what is network exactly. The word of network is really close to us since we always use it or maybe we not realize it. So, to be more details I will explain. Network is the collections of computers and devices that connect via communication devices or transmission media. One of application of network is resource sharing such as hardware and software. Communication also application of network,for example email,message broadcast.

Type of Communication Devices

• dial-up modem
• digital modem
• wireless modem
• network card
• wireless access point
• router
•  switch

Transmission media is divided into two. Let me explain mean of transmission media which are materials or substances that capable of carrying one or more signals. Two types of them are wired and wireless. Example for wired such as coaxial cable and fiber optic. For wireless such as cellular radio and infrared.

Advantages of network is easy communication and speed. Like what I'm doing now is one of communication using network,blog,so I can communicate with you guys. Moreover,we can share file,data and information like in whatsapp we share video,audio and picture.

Network Architecture

For this network architecture maybe there are people that never listen to this words. Network architecture is the design of computers,devices, and media on a network. 

Two types  of network architecture :

1. Client/server network
2. Peer to peer network

Client/server network,means one or more computer can act as server while the other computers will request services form the server.

Peer to peer network-each computer,called a peer, has equal responsibilities and capabilities,sharing hardware(such as printer),data, or information with other computers on the peer-to-peer network.

Network Topology

A network topology refers to the layout of the computers and devices in a communication networks

Three types of network topology :

• Bus Topology
• Star Topology
• Ring Topology
