Transmission media is the material pathway that connects computers, different kinds of devices and people on a network. It can be compared to a superhighway carrying lots of information. Transmission media uses cables or electromagnetic signals to transmit data.Know More
There are two types of transmission media used in communications. The first type is called bound transmission media or guided media. It uses physical links, such as coaxial or fiber optic cables, to transmit data to the desired connection. Most cables are made of copper and bound by some form of jacket material. Because they are tangible, this type of media is limited to a fixed location.
The second type is unbounded media, also known as unguided or wireless media. Unlike bound media, it transmits data without any physical connectors between two communicating devices. Instead, it uses microwave, infrared or radio signals to transmit information.Learn more about Computers & Hardware
Major technological advances that allow computers to run faster, decrease in size and become more efficient delineate the five generations of computers. First-generation computers used vacuum tubes, second-generation computers had transistors, while third-generation computers advanced to integrated circuits. Fourth-generation computers contain microprocessors, and future, fifth-generation devices will focus on artificial intelligence.Full Answer >
The instruction cycle is the basic operation cycle of computers, and it is the time period during which the computer fetches an instruction and executes it. It consists of up to six phases, which are fetch instruction, decode instruction, evaluate address, fetch operand, execute and store results.Full Answer >

Approximately 84 percent of Americans owned computers in 2013, including desktops, laptops, netbooks, notebooks, tablets, handheld computers, smartphones and other hand held devices, according to the 2013 American Community Survey. A total of 92 percent of households in the District of Columbia, Maryland and Virginia area owned a computer, which was the highest of any other area, according to the survey. The U.S. Census Bureau relies solely on this survey's data to determine small area estimates for social and demographic characteristics.Full Answer >
