Advantages and disadvantages of metropolitan area network (MAN)

A metropolitan area network MAN is a network which covers a city or a large university campus. MAN usually involves connection of fiber optics wires to boost data transfer speed. MAN depends upon different technologies to establish a network. Some of these technologies are mentioned below Its range is within kms. ATM Asynchronous transfer mode was developed in to transfer digital data fast. In ATM data is distributed online in the form of small fixed size packets.

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?

Chapter 1: What is a Network?

We use radio frequency for communication in this network. LAN Local This type of network is large than a LAN, which is mostly limited to a single building or site. The devices in a WAN are connected through public infrastructure such as a telephone system or through leased lines or even satellites. MAN networks are usually operated at airports, or a combination of several pieces at a local school. Local Area Network cannot cover cities or towns and for that Metropolitan Area Network is needed, which can connect city or a group of cities together.

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.

Chapter 7. Telecommunications, the Internet, and Information System Architecture. The electronic transmission of information over distances, called telecommunications, has become virtually inseparable from computers: Computers and telecommunications create value together. Components of a Telecommunications Network. Telecommunications are the means of electronic transmission of information over distances.

Computer Network Types

Office, school, any area that presented at a limited distance is called the campus. The Providing of the network at a particular location is called a Campus Area Network. Now How the Campus Area Network is get connected?

Cisco Network Templates. Public libraries and government agencies typically use a MAN. Computer hardware resources like printers, modems, DVD-Rom drives and hard disks can be shared with the help of local area networks. This will reduce cost of hardware purchases.

What is Bus Topology, Advantages and Disadvantages of Bus Topology

Wide Area Network Advantages and Disadvantages

Nowadays, more and more networks are operating without cables, within the wireless mode. Wireless LANs use high-frequency radio signals, infrared beams, or lasers to speak between the workstations, file servers, or hubs. Wireless LAN is formed by connecting different devices through wireless communication to form an area network.

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. Extranet: An extranet is a communication network based on the internet protocol such as Transmission Control protocol and internet protocol. It is used for information sharing. The access to the extranet is restricted to only those users who have login credentials.

Sending local emails.

Advantages and disadvantages of metropolitan area network (MAN)

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.

Он не мог поверить, что дожил до подобной катастрофы. Он отдал распоряжение вырубить электропитание, но это все равно произойдет на двадцать минут позже, чем следует. Акулы со скоростными модемами успеют скачать чудовищные объемы секретной информации через открывшееся окно. Из размышлений об этом кошмаре его вывела Соши, подбежавшая к подиуму со свежей распечаткой. - Я кое-что нашла, сэр! - возбужденно сказала.  - Висячие строки в источнике. Альфа-группы повсюду.

Types of Computer Networks: LAN, MAN, WAN, VPN

 Поссорились. На мгновение Беккер задумался. Потом изобразил смущенную улыбку.

 Коммандер, не думаете же вы… - Сьюзан расхохоталась. Но Стратмор не дал ей договорить.

 - Я поняла это, сделав пробу системных функций. Мы выделили отдаваемые им команды - смотрите. Смотрите, на что он нацелен.

Чаша быстро приближалась к нему справа. Люди отпивали по глотку вина, крестились и поднимались, направляясь к выходу. Хорошо бы помедленнее.

ТРАНСТЕКСТ заклинило на восемнадцать часовМысль о компьютерном вирусе, проникшем в ТРАНСТЕКСТ и теперь свободно разгуливающем по подвалам АНБ, была непереносима. - Я обязан об этом доложить, - сказал он вслух. В подобной ситуации надо известить только одного человека - старшего администратора систем безопасности АНБ, одышливого, весящего четыреста фунтов компьютерного гуру, придумавшего систему фильтров Сквозь строй. В АНБ он получил кличку Джабба и приобрел репутацию полубога.

Less expensive: It is less expensive to attach MAN with WAN.
