Modem: What is a Modem? Types of Modems

by Dinesh Thakur Category: Computer Network

Modem is abbreviation for Modulator – Demodulator. Modems are used for data transfer from one computer network to another computer network through telephone lines. The computer network works in digital mode, while analog technology is used for carrying massages across phone lines.

What is a computer network? Advantages of Network .

by Dinesh Thakur Category: Computer Network

A computer network consists of two or more computers that are linked in order to share resources such as printers and CD-ROMs, exchange files, or allow electronic communications. The computers on a computer network may be linked through cables, telephone lines, radio waves, satellites, or infrared light beams.

What is Switching

by Dinesh Thakur Category: Computer Network

Switching is the most valuable asset of computer networking. Every time in computer network you access the internet or another computer network outside your immediate location, or your messages are sent through a maze of transmission media and connection devices. The mechanism for exchange of information between different computer networks and network segments is called switching in Networking. On the other words we can say that any type signal or data element directing or Switching toward a particular hardware address or hardware pieces.

what is network? Types of Network

by Dinesh Thakur Category: Computer Network

Computer Networks fall into three classes regarding the size, distance and the structure namely: LAN (Local Area Network), MAN (Metropolitan Area Network), WAN (Wide Area Network). Before we discussing about type of network we can discuss about what is a network.

What is 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.

What is a Computer Network? Uses of Computer Networks.

by Dinesh Thakur Category: Computer Network

During 20th century the most important technology has been the information gathering, its processing and distribution. The computers and communications have been merged together and their merger has had a profound effect on the manner in which computer systems are organized.

Network Connection Types

by Dinesh Thakur Category: Computer Network

There are different types of communications connection in existence between two endpoints., Home networks, and the Internet is the one of the most commonly used examples. Many type of devices are and several different methods are used connecting to these type of network architectures.

There are different advantages and disadvantages to this type of network architectures. Connecting computers to a these type of networks, we requires some networking framework to create the connections. The two different computer network connection types are getting discussed in this page are Point-to-Point Connection and multipoint connection. The main difference between them we can getting discussed with the help of below definition.

What is IEEE 802.4 Protocol? Token Bus

by Dinesh Thakur Category: Computer Network

IEEE 802.4 Token Bus : In token bus Computer network station must have possession of a token before it can transmit on the computer network. The IEEE 802.4 Committee has defined token bus standards as broadband computer networks, as opposed to Ethernet's baseband transmission technique. Physically, the token bus is a linear or tree-shape cable to which the stations are attached.

What is Network Topology? or Network Topologies

by Dinesh Thakur Category: Computer Network

The term Network Topology defines the geographic Physical or logical arrangement of computer networking devices . The term Topology refers to the way in which the various nodes or computers of a network are linked together. It describes the actual layout of the computer network hardware. Two or more devices connect to a link; two or more links form a topology. Topology determines the data paths that may be used between any pair of devices of the network.

What is protocol? and its types - Definition

by Dinesh Thakur Category: Computer Network

Protocol Definition: It is a digital language through which we communicate with others on the Internet. protocol meaning is that it a set of mutually accepted and implemented rules at both ends of the communications channel for the proper exchange of information. By adopting these rules, two devices can communicate with each other and can interchange information. We can't even think of using the Internet without Protocols. Each protocol is defined in different terms and different use with unique name. Message travel from sender to reciever via a medium (The medium is the physical path over which a message travels) using a protocol.

Types of Servers

by Dinesh Thakur Category: Computer Network

There are many type of Serves in the Computer Networking World. Server is a machine, that can be design for interconnecting the machines with each other.Many type of the functions are performed by the servers to facilitate different uses. Let us discussed first, what is a server before getting discuss about type of servers.
