Computer Network A Network - 1698 Words

Computer network: A computer network is interconnection of more computing systems and their hardwares for storing and transmitting the data. These networks can be connected either wires or wireless. Connecting the systems without wires is called wireless technology. Connecting the computers , laptops , printers and gaming devices comes under computer network Person Area Network: Person area network is a computer network connecting the devices within the environment of an individual person. Personal area network typically includes devices like laptops, mobiles, gadgets and other personal digital assistants. Local area network: Connecting the networks within limited areas such as schools, hotels, buildings using network medium are called local area networks. This networks constitute a little geographical area . The data transfer rate is very high and reliable in these networks Metropolitan Area Network: The network which connecting the devices to a larger area like small towns covering area up to 50 km called metropolitan area networks. These networks are high speed networks that interconnect businesses with other businesses and the internet. Wide area network: The network consisting relatively large geographical area and linking states , countries and the world are wide area networks. These networks are often connected through public telephones and they can be connected through satellites Data communications: Data communication refers to exchanging the data betweenShow MoreRelatedComputer Networks And The Network1232 Words   |  5 Pages A computer network or data network is a telecommunications network which allows computers to exchange data. In computer networks, networked computing devices exchange data with each other along network links . The connections between nodes are established using either cable media or wireless media. The best-known computer network is the Internet. Network computer devices that originate, route and terminate the data are called network nodes. Nodes can include hosts such as personal computers, phonesRead MoreComputer Networks And The Network1481 Words   |  6 PagesComputer Networks Network is between two or more computers connected each other they can exchange data. For example a network allows computers to share files, users to message each other. Computer network topology is the way various components of a network for example (link, connect) which is different systems and nodes are connected and communicate with each other. A network is a set of devices, software, and cables that enables the exchange of information between them. Host devices are computersRead MoreComputer Networks And The Network974 Words   |  4 PagesA computer network is any computer or group of computers that are linked to another computer or systems of computers so they can communicate. There are several careers that involve knowledge of computer networking. Each of these positions require a particular set of skills. While the positions may sound the same, they are not. For example, the network engineer manages and designs computer networks, upgrading them and tests their security while the network administrator keeps the network running.Read MoreComputer Networks And The Network976 Words   |  4 PagesComputer Network Careers A computer network is any computer or group of computers that are linked to another computer or systems of computers so they can communicate.

Without networking standards manufacturers of networking products have no common ground on which they can build their systems. Standardization of products can make or break networking products, many companies are hesitant to support newer technology unless there is a standardization base from which to work. Different types of network standards include 802†LAN†, 802.3 â€Å"wired LAN† and 802.11 â€Å"Wireless† there is also the OSI modelRead MoreComputer Networks And The Network System1971 Words   |  8 Pagesinterconnected through the internet nowadays. The internet is the connection of assorted computer networks through a series of service providers and businesses. In order to create these networks, there needs to be devices known as routers, switches and firewalls. These devices have some very well-known vendors, such as, Cisco and Juniper. Juniper uses an operating system called Junos. Junos OS is a great network operating system because of its modularity and it’s unique and hierarchical configurationRead MoreHow Is A Computer Network?873 Words   |  4 PagesHow to Define a Computer Network No matter how it is described or reported â€Å"computer network† continue being a difficult phrase to define. Computer IT technicians do not know how to approach to a regular person, and describe the operation of a simple computer networking . In the other hand, and this is also important, â€Å"regular normal† people seem not to care how important a computer network is, and what it really means. Maybe is because most of the time the computer network always is â€Å"behind theRead MoreComputer Topology Of A Network1391 Words   |  6 PagesINTRODUCTION: The physical or network topology of a network seriously affects the network price, dependability, throughput, and approach pattern, etc, thus we want to contemplate these multiple criteria having totally different units, at the same time. However, normal ways of planning topology contemplate solely one criterion, e.g., minimizing the specified range of physical links. during this paper, we tend to propose a topology style methodology exploitation average rank, that is calculatedRead MoreComputer Network Administrator1763 Words   |  8 PagesCOMPUTER NETWORK ADMINISTRATOR A computer network (the network) is the connection of at least two or more computers for the purpose of sharing data and resources. These resources can include printers, Internet access, file sharing, and electronic mail (e-mail). In today s technological environment, most companies and businesses have some kind of network used on a daily basis. Thus, it is imperative to day-to-day operations that networks run smoothly. Companies employ at least one personRead MoreThe Technology of Computer Networks2197 Words   |  9 PagesIntroduction Computer network - a system used to link PCs or computer equipment (servers, routers, and other equipment). For data transmission can be used various kinds of electric signals, light signals or electromagnetic radiation. Computer networks can be classified according to various criteria - territorial prevalence, type of network topology, etc. One of the criteria - the type of transmission, the network is divided into wired and wireless.
