A network consists of two or more computers that are linked in order to share sources (such as printers and CDs), exchange files, or enable electronic communications. The computer systems on a network may possibly be linked by means of cables, telephone lines, radio waves, satellites, or infrared light beams. But cables and computer systems alone do not make a excellent network, so one particular early answer was to use a network hub. The Ethernet cables from the laptop connect to the device similar to the hub of a bike wheel—where all of the spokes come together in the center.

Twisted pair wire is the most broadly employed medium for all telecommunication. Twisted-pair cabling consist of copper wires that are twisted into pairs. Ordinary phone wires consist of two insulated copper wires twisted into pairs. Computer network cabling (wired Ethernet as defined by IEEE 802.3 ) consists of 4 pairs of copper cabling that can be utilized for both voice and information transmission. The use of two wires twisted together aids to minimize crosstalk and electromagnetic induction The transmission speed ranges from 2 million bits per second to 10 billion bits per second. Twisted pair cabling comes in two types: unshielded twisted pair (UTP) and shielded twisted-pair (STP). Every form comes in several category ratings, made for use in a variety of scenarios.

Computer systems connected to a network are broadly categorized as servers or workstations. Servers are typically not utilized by humans directly, but rather run continuously to provide “services” to the other computers (and their human users) on the network. Services provided can include printing and faxing, computer software hosting, file storage and sharing, messaging, data storage and retrieval, comprehensive access control (safety) for the network’s sources, and many other people.

Customers and network administrators typically have diverse views of their networks. Customers can share printers and some servers from a workgroup, which typically indicates they are in the very same geographic location and are on the exact same LAN, whereas a Network Administrator is accountable to maintain that network up and running. A neighborhood of interest has significantly less of a connection of becoming in a regional area, and should be believed of as a set of arbitrarily located users who share a set of servers, and possibly also communicate by way of peer-to-peer technologies.
