Telecommunication And Networking

In this chapter we will learn several elements consisted in Connecting A Network which are type of cables, type of cable connector and elements in Network Hardware. A. Type of Cables: Coaxial Cable Coaxial cable is a type of copper cable specially built with a metal shield and other components engineered to block signal interference. It is primarily used by cable TV companies to connect their satellite antenna facilities to customer homes and businesses. It is also sometimes used by telephone companies to connect central offices to telephone poles near customers. Some homes and offices use coaxial cable, too, but its widespread use as an Ethernet connectivity medium in enterprises and data centers has been supplanted by the deployment of twisted pair cabling. Figure 1: Coaxial Cable Fiber Optic Cable An optical fiber cable, also known as fiber optic cable, is an assembly similar to an electrical cable but containing one or more optical fibre that are used to car...

There are 4 important subdivision in Computer Network namely: a) The definition of Computer Network b) Type of Networks c) The Component of Network d) Network Architecture a) Definition of Computer Network  It can be defined as   is a set of computers connected together for the purpose of sharing resources. The most common resource shared today is connection to the Internet. Other shared resources can include a printer or a file server. Computers on a network are called nodes. The connection between computers can be done via cabling, most commonly the Ethernet cable, or wirelessly through radio waves. b) Type of Networks There are 5 different type of networks which are : LAN - Local Area Network. WAN - Wide Area Network. WLAN - Wireless Local Area Network. MAN - Metropolitan Area Network. SAN - Storage Area Network, System Area Network, Server Area Network, or sometimes Small Area Network. LAN connects network devices over a relatively ...

Apakah yang anda faham tentang Telekomunikasi, Telekomunikasi adalah teknik pengiriman atau penyampaian maklumat dari suatu tempat ke tempat yang lain. Terdapat tiga bentuk komunikasi jarak jauh yang boleh dibezakan melalui tiga cara iaitu 1. Komunikasi satu arah (Simplex)     Dalam komunikasi satu arah atau Simplex ini, pengirim dan penerima maklumat tidak menjalin komunikasi yang berkesinambungan melalui alat media yang sama seperti contoh Television dan radio. 2. Komunikasi Dua Arah (Duplex)     Dalam Komunikasi dua arah atau Duplex, pengirim dan penerima maklumat dapat menjalin komunikasi yang berkesinambungan melalui alat media yang sama seperti contoh Telefon bimbit dan VOIP. 3. Komunikasi Semi Dua Arah (Half Duplex)     Dalam Komunikasi Semi dua arah atau Half Duplex, pengirim dan penerima maklumat berkomunikasi secara bergantian namun tetap berkesinambungan seperti contoh Walkie talkie, Chat Room dan lain-lain.

As We know, there are 6 basic elements of communication Process that consist of Sender/Source (Enconder), Massage, Channel, Receiver (Decoder) Noise and the last one is Feedback. For Example of comunication model:
