A wide area network WAN is a telecommunications network that extends over a large geographic area for the primary purpose of computer networking. Wide area networks are often established with leased telecommunication circuits.

L ocal A rea N etwork is a group of computer and peripheral devices that are connected in a limited area such as school, laboratory, home, or office building.

Wide area network

Local area network is the computer network that connects computers within the limited area such as schools, colleges or universities. Local area networks , generally called LANs , are privately-owned networks. They provide a useful way of sharing resources between end users. The resources such as printers, file servers, scanners, and internet are easily sharable among other connected computers in a network. A typical Wi-Fi LAN operates one or more wireless access points that devices within coverage area connect to. These access points, manage network traffic which is flowing to and from the connected devices. A typical Ethernet LAN consisting of an ethernet cable to which all the machines are attached, like in our school labs, number of computers connected to each other through the common ethernet cable.

A network consists of two or more computers that are linked in order to share resources such as printers and CDs , exchange files, or allow electronic communications. The computers on a network may be linked through cables, telephone lines, radio waves, satellites, or infrared light beams. It is generally limited to a geographic area such as a writing lab, school, or building. Computers connected to a network are broadly categorized as servers or workstations. Servers are generally not used 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, software hosting, file storage and sharing, messaging, data storage and retrieval, complete access control security for the network's resources, and many others.

The Advantages and Disadvantages of WANs

Network is a medium that connects multiple computer systems with a common communication link. A Wide Area Network WAN is a computer network that connects computers within a large geographical area comprising a region, a country, a continent or even the whole world. Wide area networks , generally called WANs, are mostly public, leased or privately-owned networks. They provide a useful way of sharing resources between the end users such as the long-distance transmission of data, voice, image, and information over large geographical areas. Wide Area Network as its name suggests it must be able to grow as needed to cover multiple cities, even countries, and continents whereas Local Area Network as its name suggest it is able to cover single campus, single office, or a single building. A dedicated connection is a communications medium or other facility dedicated to a particular application such as telephony operation or internet service providing. Some examples of WAN are below:.

Do you have a wide area network WAN at your company? If you operate globally, you probably do. They make it possible for large organizations to communicate internally faster and more efficiently. Like every technological tool, you need to use them in the right scenario to benefit from them. WANs are large communication networks that connect locations over a wide geographical area, including cities, states, countries, and continents. A leased line is a direct connection between two points set up by a telecommunications carrier, like a T-1 channel. WANS have been around for a while with some people tracing their roots to the s, s and even the s.

Wide area network WAN is a type of network that provides transmission of voice, data, images, and videos over the large geographical area. The transmission of data is carried out with the help of hubs, switches, fiber optics, modem, and routers. To transfer data from any computer over the internet we use some technologies including:. Wan covers a large geographical area of km or more If your office is in different cities or countries then you can connect your office branches through wan. ISP Internet service provider can give you leased lines by which you can connect different branch offices together. All office branches can share the data through the head office server. You can get back up, support, and other useful data from the head office and all data are synchronized with all other office branches.


Advantages of a wide area network (WAN) Covers large geographical area: Centralized data: Get updated files and data: A lot of application to exchange messages: Sharing of software and resources: Global business: High bandwidth: Distribute workload and decrease travel charges.


Local Area Networks (LAN) and Wide Area Networks (WAN), Difference between LAN and WAN

Wide Area Network WAN is a collection of various local area networks LAN to transmit the data to the large geographical area in the form of voice, video, image, files. A LAN is a small area network that connects the network only for a limited distance. Ethernet and wifi fall under the local area network. Merely, the network of all local area networks is called a Wide area network WAN.

Я сам попытался отправить твой маячок, но ты использовала для него один из новейших гибридных языков, и мне не удалось привести его в действие. Он посылал какую-то тарабарщину. В конце концов пришлось смирить гордыню и вызвать тебя .

Танкадо прошел проверку на полиграф-машине и пережил пять недель интенсивного психологического тестирования. И с успехом его выдержал. Ненависть в его сердце уступила место преданности Будде. Еще через четыре месяца Энсей Танкадо приступил к работе в Отделении криптографии Агентства национальной безопасности США. Несмотря на солидный заработок, Танкадо ездил на службу на стареньком мопеде и обедал в одиночестве за своим рабочим столом, вместо того чтобы вместе с сослуживцами поглощать котлеты из телятины и луковый суп с картофелем - фирменные блюда местной столовой.

 Самообразование за тюремной решеткой. Хейл засмеялся. - Нет, серьезно, Сьюзан, тебе никогда не приходило в голову, что это все-таки возможно и что Танкадо действительно придумал невзламываемый алгоритм.

И он решил не реагировать на сообщение. ГЛАВА 79 Стратмор спрятал пейджер в карман и, посмотрев в сторону Третьего узла, протянул руку, чтобы вести Сьюзан за. - Пошли.

Коммандер спас ей жизнь. Стоя в темноте, она испытывала чувство огромного облегчения, смешанного, конечно же, с ощущением вины: агенты безопасности приближаются. Она глупейшим образом попала в ловушку, расставленную Хейлом, и Хейл сумел использовать ее против Стратмора. Она понимала, что коммандер заплатил огромную цену за ее избавление. - Простите меня, - сказала .
