1.0 INTRODUCTION
A computer network and communication is defined as a collection of computers and devicesconnected by communications channels that facilitates communications among users and allowsusers to share resources with other users. Computer Network

A computer network is a system of interconnected computers and peripheral devices. For example, it may connect computers, printers, scanners and cameras. Using hardware and software, these interconnected computing devices can communicate with each other through defined rules of data communications. In a network, computers can exchange and share information and resources. A computer network may operate on wired connections or wireless connections. When two or more networks are linked or connected and are able to communicate with one another using suitable hardware and software, it is called an internetwork.

Communications
Communications is about the transfer of information from a sender, across a distance, to a receiver. Using electricity, radio waves or light, information and data in the form of codes are transmitted through a physical medium such as wire, cable, or even the atmosphere. Therefore, in order to make communications possible from computers, across telephones and radios and back to computers and other digital devices again, there must be a signal translator, which we call-a modem. The modem, which is short for modulator or demodulator, converts digital signals into analog and back again into digital signals for information to move across the telephone line.

2.0 MOBILE COMPUTING
2.1Definition
Mobile computing refers to the use of small and portable computing devices in wireless enabled networks that provide wireless connections to a internet or central main server. These devices include laptops, notebook PCs, tablet PCs, palmtops, personal digital assistant (PDAs) and other hand held devices. A radio-signaling device is installed inside these devices for receiving and transmitting electronic data. Mobile computing has enabled users to remain connected while on the move. High end users can opt for satellite based networking which provides wireless connectivity anywhere in the world. However, this technology is costly and will take many years to become as affordable as Wi-Fi and WiMax. 2.2Specification, services, and frequencies of Mobile Computing The latest 4G device from T-mobile is the Samsung Galaxy S 4G.This phone works on T-Mobile's HSPA+ 4G network, which uses a different technical standard than Sprint or Verizon Wireless' 4G networks. The Samsung Galaxy S 4G is the wireless carrier's first smartphone  that is capable of delivering theoretical peak download speeds of up to 21 Mbps while in one of T-Mobile's 4G coverage areas. In addition to fast speeds, the Galaxy S 4G has a large,...
