defined as a subset of telecommunication involving the transmission of data to and from computers and components of computer systems. More specifically data communication is transmitted via mediums such as wires‚ coaxial cables‚ fiber optics‚ or radiated electromagnetic waves such as broadcast radio‚ infrared light‚ microwaves‚ and satellites. Data Communications = Movement of computer information by means of electrical or optical transmission systems Information can be represented using analog signals

A computer network is any set of computers or devices connected to each other via some form of transmission medium with the ability to exchange data. Here information is presented in a form which is agreed upon by the parties creating and using the data. A computer network must be able to meet a certain number of criteria. The most important of these

sophisticated network and multimedia services‚ the main target of HSDPA is to increase user peak data rates‚ quality of service‚ and to generally improve spectral efficiency for downlink asymmetrical services. HSDPA can achieve theoretical data transmission speeds of 8-10 Mbps(megabits per second). Though any data can be transmitted‚ applications with high data demands such as video and streaming music are the focus of HSDPA. Hence by implementing HSDPA in wifi hotspots theoretical data rates of about
