Network ???

Hello again everyone, this is my third post in my blog. In this post, I am going to share with you on what I had learned in science computer about network. Actually, this is the first topic for my science computer subject in semester two. So, what is network??

          Network is a collection of computers and devices that are connected together via communications devices and transmission media. There are three applications of network which are resource sharing, information sharing and communications.

          In network, there are communications devices. Communications devices are any type of hardware capable of transmitting data, instructions and information between a sending and receiving devices. Here are examples of communication devices, Dial up modem, Digital modem, Wireless modem, Wireless access point, Network card, Router, Hub and Switch.

          In network, there is also transmission media, which is the material capable of carrying one or more signals in a communications device. There are two types of transmission media firstly physical transmission which are twisted pair cable, Coaxial cable and Fibre optic cable. Secondly, wireless transmission media which are Infrared, Broadcast radio, Cellular radio, Microwave, Communication satellites

          In learning network, we also should know the network architecture. Definition of network architecture is the design of computers device and media in network. There are two types of network architecture which are client server and peer to peer.

          Network topology. Definition of network topology is refers to the layout of the computers and devices in a communication network. There are physical topology and logical topology. Also there are types of network topology which are Bus topology, Ring topology and Star topology.

         Network can also be classified into three which are Local Area Network (LAN), Metropolitan Area Network (MAN) and Wide Area Network (WAN). LAN provide the fastest internet connection, WAN is slower than LAN but faster than WAN. WAN provide the slowest internet connection but it covers the largest geographical area. LAN covers the smallest and WAN covers larger than LAN but smaller than WAN.

          As a conclusion, I can say that there is a lot to learn about networks. If you are interested, you can search and read about networks. If you would prefer books, then I want to recommend you to read the Shelly Cashman books. Pretty simple to understand, also there are a lot of illustrations and pictures in that book. Thank you for reading my post.
