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. Businesses, as well as schools and government entities, use wide area networks to relay data to staff, students, clients, buyers and suppliers from various locations across the world.

Local Area Network | Advantages and Disadvantages of LAN

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. Software companies work over the live server to exchange updated files. So all the coders and office staff get updated version of files within seconds. A lot of web applications are available like Facebook messenger, WhatsApp, Skype by which you can communicate with friends via text, voice and video chat.

Like LAN we can share software applications and other resources like a hard drive, RAM with other users on the internet. In web hosting, we share computer resources among many websites. Now everyone with computer skills can do business on the internet and expand his business globally.

There are many types of business like a shopping cart, sale, and purchase of stocks etc. If you get leased lines for your company then it gives high bandwidth than normal broadband connection. You can get a high data transfer rate that can increase your company productivity. Another benefit of wide area network is that you can distribute your work to other locations. For example, you have an office in the U. S then you can hire people from any other country and communicate with them easily over WAN.

It also reduces your travel charges as you can monitor the activities of your team online. WAN has many technologies combined with each other which can create a security gap. As data transferred on the internet can be accessed and changed by hackers so firewall needs to be enabled in the computer.

Some people can also inject a virus into the computer so antivirus software needs to be installed. Other security software also needs to be installed on different points in WAN. Setting up WAN for the first time in office costs higher money. It may involve purchasing routers, switches, and extra security software. As WAN covers a lot of areas so fixing the problem in it is difficult. Most of WAN wires go into the sea and wires get broken sometimes. It involves a lot of resources to fix lines under the sea.

In ISP Internet service provider head office many of internet lines, routers are mixed up in rooms and fixing issues on the internet requires a full-time staff. In some areas, ISP faces problems due to electricity supply or bad lines structure. Customers often face connectivity issues or slow Internet speed issues. The solution to this is to purchase a dedicated line from ISP.

LAN vs WAN: What's the Difference?

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. Workstations are called such because they typically do have a human user which interacts with the network through them.

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.

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. It connects different LANs and other networks for communication and to share and access data from one user to another user over a longer distance. Many user computers, organizations, employees use the WAN to communicate with another user computer, employees to access the information, discuss and share data all around the world. The third-party service providers are involved in the connection between the users and the internet.

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.

Нам нужно число. Он нас надул. Это кольцо - обман. - Червь удвоил скорость! - крикнула Соши.  - Штрафная санкция. На центральном экране прямо под извещением об ошибке ВР представила зрителям ужасающую картину.


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.


Его комментарий отличался бесстрастностью опытного полевого агента: - Эта съемка сделана из мини-автобуса, припаркованного в пятидесяти метрах от места убийства. Танкадо приближается справа, Халохот - между деревьев слева. - У нас почти не осталось времени, - сказал Фонтейн.  - Давайте ближе к сути дела. Агент Колиандер нажал несколько кнопок, и кадры стали сменяться быстрее.

Стратмор сидел за современным письменным столом с двумя клавиатурами и монитором в расположенной сбоку нише. Стол был завален компьютерными распечатками и выглядел каким-то чужеродным в этом задернутом шторами помещении. - Тяжелая неделя? - спросила .

 - Какой же может быть ответ. - Нам необходимо число, - напомнил Джабба.  - Шифр-убийца имеет цифровую структуру. - Тихо, - потребовал Фонтейн и повернулся к Сьюзан.  - Мисс Флетчер, вы проделали уже немалую часть пути.
