Terrestrial microwaves are in the low gigahertz range, which limits all communications to line-of-sight. These Earth-orbiting systems are capable of receiving and relaying voice, data, and TV signals. Cellular and PCS systems use several radio communications technologies. The systems divide the region covered into multiple geographic areas. Each area has a low-power transmitter or radio relay antenna device to relay calls from one area to the next area. Wireless LANs use spread spectrum technology to enable communication between multiple devices in a limited area.

Computer network

An example of a WAN is the much-used and loved, Internet. Servers - Servers are computers that hold shared files, programs, and the network operating system.

Servers provide access to network resources to all the users of the network.

There are many different kinds of servers, and one server can provide several functions. For example, there are file servers, print servers, mail servers, communication servers, database servers, print servers, fax servers and web servers, to name a few. Clients - Clients are computers that access and use the network and shared network resources. Client computers are basically the customers users of the network, as they request and receive services from the servers.

Transmission Media - Transmission media are the facilities used to interconnect computers in a network.

Transmission media are sometimes called channels, links or lines. Shared data - Shared data are data that file servers provide to clients such as data files, printer access programs and e-mail. Shared printers and other peripherals - Shared printers and peripherals are hardware resources provided to the users of the network by servers.

Hardware and Networking Interview Questions & Answers

Resources provided include data files, printers, software, or any other items used by clients on the network. The NIC prepares formats and sends data, receives data, and controls data flow between the computer and the network. On the transmit side, the NIC passes frames of data on to the physical layer, which transmits the data to the physical link.

On the receiver's side, the NIC processes bits received from the physical layer and processes the message based on its contents.

Local Operating System - A local operating system allows personal computers to access files, print to a local printer, and have and use one or more disk and CD drives that are located on the computer. Induced noise comes from sources such as motors and other electronic appliances.
