Network technology. What is it?
Network technology or computer network and the data network is a
telecommunication network, in which one integrates computer and server in order to exchange data. In computer networking, networked computing
devices that transmit data along data connections to each other.
The connections (network connections) between nodes are established
either by cable or wireless media. The best-known computer network is the Internet. Network
computer devices that have their origin in the
dissemination of data are
called network nodes. Such nodes can
contain hosts, such as servers, switches and PCs, and network
hardware. Should be a device able to exchange information with
other devices, then must be linked to each other at least two
The network technology supports applications such as access to the
World Wide Web, the sharing of
application and storageservers, printers and fax machines, the use of
e-mail and instant messaging applications. Computer networks, however, differ in the used
physical media that are needed in order to transmit their signals.
The communication protocols are there to organize the network
traffic and the size of the network. The physical layout of a
network is somewhat less important than the topology in which
network nodes are connected in the rule. Most diagrams are developed to describe a physical
network technology are therefore more likely topologically as
geographically. The symbols on the diagrams typically refers to network connections
and network nodes. About the devices of a computer network especially a variety of communication media,
such as electrical cable (HomePNA, power line communication, G.hn),
optical fiber (fiber communication) and radio waves are (wireless
networks). The physical layer and the data link layer - in the OSI
model, which are defined in Layers 1 and 2. A
widely used family of
communication media used in the local area network (LAN) is known
as the Ethernet. The media and protocol
standards that allow communication between networked devices via
Ethernet are defined as IEEE 802.3. The
Ethernet data transmission
usually runs over copper and fiber optic cable. Wireless LAN
standards (such as those defined by IEEE 802.11), or other
radio waves, infrared signals, however, to use as a transfer
medium. However, power line communications uses the electrical
wiring of a building to transfer data.
A network interface controller (NIC), a particular computer hardware that provides the ability to access the
communication media, and also has the ability to process low-level
network information. For example, the network card accept a "connector" for a cable or
have an antenna for wireless transmission and reception and associated circuits.
In addition, the network card allows access to an identifier for either a network
card or the computer as a whole. For Ethernet networks, each network
interface controller has a unique Media Access Control (MAC)
address, which is typically stored in the permanent memory of the control unit.
