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

Outline Manual Transmission Cars Purpose - To explain to the class about manual transmission cars and how to drive one. Central Idea – Driving a manual transmission car is very different from driving an automatic transmission car I. Introduction Today about 6 million people drive a car in the United States‚ but the percentage of those people that drive a manual transmission is significantly less than those who drive automatic. In every country in Europe

Abstract: VLSI based Accident information and car security system deals with the concern of saving the victim ‚ who get trapped in accident and also about the car security. Accident of the car is detected using pressor sensors which are fixed in car. Accident information to the nearest hospital is carried out with the help of RF communication. The location of the car is found using the GPS technique. The security of car is ensured by using password. The theft information is sent to the owner’s mobile

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

cracks‚ uneven tire wear‚ brake fluid leakage) • Look under the car for: o oil spots‚ or o transmission fluid or o power steering fluid or o shock absorber fluid. • Open the hood and check belts and hoses for cracks or wear. • Radiator coolant should be a clean‚ greenish (or blue or yellow) color. • Pull out the oil dipstick. Oil should not be gummy or grayish or smell burnt. • Check automatic transmission fluid‚ should be clear and reddish. • Check the fluid level in the master cylinder as well

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

Generally‚ the data transmission rate of wide area network is lower than local area network (LAN)‚ but with the development of technology‚ this data transmission rate is improved dramatically‚ it could achieve 2.4 Gbps or even higher currently. Thus‚ it could meet a great number of requirements. After that‚ it will analyze the key technologies
