Computer Networks: Understanding Computer Networks
Understanding
of computer network is a collection of computers and other devices that
are connected to the computer support in a coalition. Media
can be through a computer network cables or wireless computer network
allowing users are able to exchange information, such as documents and
data, can also do the printing on the same printer and together using
the hardware and software are connected to the network. Each computer, or devices that are connected in a network is called a node. In a computer network can have two, tens, thousands or even millions of nodes.
Computer
Network is a group of autonomous computers interconnected with each
other using a communication protocol through the medium of
communication so that they can share information, programs - programs,
use of shared hardware such as printers, hard drives, and so on. Besides
computer network can be defined as a collection of a number of
communication terminals located in various locations consisting of more
than one interconnected computers.
Benefits gained in building computer networks, namely:
* Sharing resources
Sharing
resources intended for the entire program, equipment or other
peripherals can be utilized by any person who is on a computer network
without being influenced by the location and the influence of the user.
* Media Communication
Computer
networks allow communication between users, both for the teleconference
and to send a message or other important information.
* Data Integration
Computer
networks can avoid reliance on a central computer, because every
process data should not be done on one computer only, but can be
distributed to other places. Therefore, it is then able to form an integrated data that allows users to acquire and process information at any time.
* Development and Maintenance
The
development tools are simple and cost-saving, because every purchase
components such as printers, so no need to buy a computer printer there
but just one piece because the printer can be used together - together.
The
computer network also allows users to take care of the hard drive and
other equipment, for example, to provide protection against virus
attacks the wearer enough to focus on the hard drive on a computer
center.
* Data Security
Computer Network Systems can provide protection against data. Since
the granting and setting permissions to users, as well as technical
protection against hard drive so that the data get effective protection.
* More Resource Efficient and Current Information
With the use of shared resources - together, will get the maximum results and high quality. In
addition the data or information accessed is always new, because any
changes that occur can be readily immediately known by every user.
