What are the uses of multimedia technology?

Answer 1

Basic multimedia communication technology tends to cover a range of multimedia devices, such as sound cards and graphic cards that allow users to create visual presentations that output sound and /or images. Multimedia generally means the combination of two or more continuous media. The two media are normally audio and video, sound plus moving pictures. For example the digital camera may be used externally to the PC, and allows the user to record images. When connecting the camera to the computer, using a cord, images will be formatted and printed. Various computers have sound cards stored within them, this allows output of sound from speakers through the use of CD's, and other formats that may have music attached to it. Sound cards allow individuals to listen to music played or stored on their computer. Whereas Communications technology refers to the transmission of data from one computer to another from one device to another. Computer systems refer to an entire working computer. All computer systems consist of various components they include the case of the computer the power supply and many other components. The Motherboard in a computer that manages the communication and function of all information. The Processor is another term for (CPU) Control Panel Unit. A microprocessor chip, the CPU is the brain of the computer; it uses mathematical functions to perform calculations. Random Access Memory Also referred to as the (RAM) holds the application programs and data in current use, it may also be occupied by software as operating systems and interpreters. Computer systems also include a Bus, the Hard Drive which has encoding data on the hard drive there has been two approaches firstly being the MFM, and the next being RLL. Other components include Peripherals, Monitor, Keyboard, and various Pointed Devices including Joysticks. Computer Networks Computer networks are able to achieve communication between a couple of computers. Networks are split into three parts. Local Area Network A Local Area Network is also known as a (LAN) they are privately owned networks within a single building or campus. LANs are distinguished from other kinds of networks by three characteristics (1) their size, (2) their transmission technology, and (3) their topology. Hub This is a LAN device that broadcasts the information it receives to all attached devices and segments of the network. Bridge This limits the collision domain, can extend network distances, and can also filter packets on their MAC addresses and ease congestion. Router These have two functions firstly to determine the best path to a destination and to share path information the "route" with other routes. A router can also connect networks using different media and architectures, which enable them to determine the best path for a packet to reach another network. They can also filter broadcasts. Network Interface Card The Network Interface Card allows devices to connect to the network. They provide connections for any type of networking media, including wireless media. Internal hardware installed within computer amongst other devices that allow them to communicate on a network. Metropolitan Area Network This is constructed of LANs that are interconnected across a city or metropolitan area. An example of a MAN is the Cable Television network available in many cities. MANs require routers, telephone and ATM switches, and microwave antennas. They produce single points of connection between each LAN. ATM Switch A network device which is used by telecommunications companies like the local telephone company to support multiple connections on an ATM network. Wide Area Network This is also referred to as a (WAN) Two or more LANs or MANs, which are interconnected using slow-speed connections over telephone lines.

Modem A modem is a device used by telecommunications companies like the local telephone company to support multiple connections on an ATM network.
