Computer Network Types
There are various types of computer networks available. We can categorize them according to their size as well as their purpose. The size of a network should be expressed by the geographic area and number of computers, which are a part of their networks. It includes devices housed in a single room to millions of devices spread across the world. What is LAN? What is WAN? What is MAN?
A computer network is a group of computers that use a set of common communication protocols over digital interconnections for the purpose of sharing resources located on or provided by the network nodes. The interconnections between nodes are formed from a broad spectrum of telecommunication network technologies, based on physically wired, optical, and wireless radio-frequency methods that may be arranged in a variety of network topologies. The nodes of a computer network may include personal computers , servers , networking hardware , or other specialised or general-purpose hosts. They are identified by hostnames and network addresses. Hostnames serve as memorable labels for the nodes, rarely changed after initial assignment.
A local area network LAN is a collection of devices connected together in one physical location, such as a building, office, or home. A LAN can be small or large, ranging from a home network with one user to an enterprise network with thousands of users and devices in an office or school. Regardless of size, a LAN's single defining characteristic is that it connects devices that are in a single, limited area. A LAN comprises cables, access points, switches, routers, and other components that enable devices to connect to internal servers, web servers, and other LANs via wide area networks. The rise of virtualization has also fueled the development of virtual LANs, which enable network administrators to logically group network nodes and partition their networks without a need for major infrastructure changes. For example, in an office with multiple departments, such as accounting, IT support, and administration, each department's computers could be logically connected to the same switch but segmented to behave as if they are separate.

Before we discussing about type of network we can discuss about what is a network. In the today world, Two devices are in network if a process in one device is able to exchange information with a process in another device. Networks are known as a medium of connections between nodes set of devices or computers. A network is consist of group of computer systems, servers, networking devices are linked together to share resources, including a printer or a file server. The connections is established by using either cable media or wireless media.
In computer networks, networked computing devices exchange data with each other using a data link. The best-known computer network is the Internet. Network computer devices that originate, route and terminate the data are called network nodes. Two such devices can be said to be networked together when one device is able to exchange information with the other device, whether or not they have a direct connection to each other. Computer networks support an enormous number of applications and services such as access to the World Wide Web , digital video , digital audio , shared use of application and storage servers , printers , and fax machines , and use of email and instant messaging applications as well as many others.

Computer Networks is an international, archival journal providing a publication vehicle for complete coverage of all topics of interest to those involved in the computer communications networking area.
A computer network is a group of computers linked to each other that enables the computer to communicate with another computer and share their resources, data, and applications. A computer network can be categorized by their size. A computer network is mainly of four types :. It is a low range network.

Used for everything from accessing the internet or printing a document to downloading an attachment from an email, networks are the backbone of business today. The smallest and most basic type of network, a PAN is made up of a wireless modem, a computer or two, phones, printers, tablets, etc. These types of networks are typically found in small offices or residences, and are managed by one person or organization from a single device. Enterprises typically manage and maintain LANs.
Чепуха. Ты никогда не смог бы проникнуть в почту коммандера. - Ты ничего не понимаешь! - кричал Хейл. - На его компьютере уже стоял жучок! - Он говорил, стараясь, чтобы его слова были слышны между сигналами.
-Consists of connecting several computer networks based on different protocols. -Requires the definition of a common interconnection protocol on top the local.
У них было много общего: настойчивость, увлеченность своим делом, ум. Иногда ей казалось, что Стратмор без нее пропадет; ее любовь к криптографии помогала коммандеру отвлечься от завихрений политики, напоминая о молодости, отданной взламыванию шифров. Но и она тоже многим была обязана Стратмору: он стал ее защитником в мире рвущихся к власти мужчин, помогал ей делать карьеру, оберегал ее и, как сам часто шутил, делал ее сны явью. Хотя и ненамеренно, именно Стратмор привел Дэвида Беккера в АНБ в тот памятный день, позвонив ему по телефону. Мысли Сьюзан перенеслись в прошлое, и глаза ее непроизвольно упали на листок бумаги возле клавиатуры с напечатанным на нем шутливым стишком, полученным по факсу: МНЕ ЯВНО НЕ ХВАТАЕТ ЛОСКА, ЗАТО МОЯ ЛЮБОВЬ БЕЗ ВОСКА. Дэвид прислал его после какой-то мелкой размолвки. Несколько месяцев она добивалась, чтобы он объяснил, что это значит, но Дэвид молчал.
Сьюзан слушала его безучастно, от воя сирены у нее закладывало уши.
