A multiplexer allows multiple users or applications to share a common physical medium by allocating bandwidth appropriately. Expand V-SAT, ATM, FTP, EDI. 14A. V-SAT: Very Small Aperture Terminal ATM: Asynchronous Transfer Mode FTP: File Transfer Protocol EDI: Electronic Data Interchange. LONG ANSWER QUESTIONS Explain briefly any three LAN Components? A. Server: A network server is a computer designed to process requests and deliver data to other (client) computers over a local network or the Internet. A client is a that accesses a service made available by a . Client: Hubs: A network hub acts as a centralized point for data transmission to computers in a LAN. When data from one computer reaches the hub it is broadcast to every computer in the network regardless of where the data is intended to go. Explain the function of a Modem with a neat diagram? 2A. A modem is a that enables a to transmit over MODEM(MOdulator–DEModulator ): telephone or cable lines . Computer information is , whereas information transmitted over telephone lines is in the form of waves. A modem the Digital signals into analog signals (Modulate) and converts the Analog signal into Digital signal(Demodulate). Modem is only device to connect our computer with internet. The following diagram explains how the connections are made. Modems are mainly two internal modems and external modems Internal Modems: Internal modems are basically integrated on a chip. These are put up into the PCI slots of the computer. There is no need of any external power supply for internal modems. These modems use the power supply of the PC. Their installation in PC is quite very simple External Modems: A serial cable connection is needed to connect an external modem to a PC. These modems use their own power supplies. These modems have their independent controls. External modems are many types as like Cable modem and DSL modem, etc.,
