Computer Peripheral equipment (also commonly referred to as input – output devices), is any equipment wired or wireless that might be used to give a computer or a set of computers on a computer network more functionality or capability.
Strictly speaking, any device that is not strictly required for the computer to function is called peripheral equipment. As such even the keyboard or mouse is a peripheral device. Although termed “peripheral” computer peripheral equipment is necessary because without it, most computers would be virtually useless.
Most computer or computer hardware manuals label peripheral equipment as an “I/O device”. I/O (input/output) devices are connected to the computer via USB, serial, parallel, bluetooth, Infrared, radio or via Wifi. Examples of I/O devices include the mouse, digital camera, keyboard, scanner, joystick, monitor, printer, speakers etc.
Modern technology and support network security has made computer peripheral devices more functional and powerful.
To facilitate easy networking, many of these peripheral devices no longer require wires; instead they receive and transmit data wirelessly. Thus you have wireless printers, mouse, keyboard, speakers etc. However, each wireless peripheral device represents a gateway through which any skilled hacker can gain entry and control of your computer network. Thus an unprotected computer or entire network can be led to believe it is receiving signals from (say) a wireless mouse, when in reality it could be receiving signals from a hacker sitting in a car across the street. All that is required is for the hacker to transmit at the right frequency and beat any protection that might exist within the receiver i.e. your computer or computer network. In fact, your computer or network does not even require having a wireless peripheral device attached. For the hacker, it is sufficient if your computer can receive wireless signals.
Atm Technology In Computer Networking
Sep 9th
ATM meaning (Asynchronous Transfer Mode) is one of the most efficient virtual network technology providing high speed connections along with dedicated paths. This technology operates on cell based fast packet switching communication method. One of the best advantages of ATM technology is that it is able to support a transfer rate between 1.544 Mbps to 10 Gbps.
The means of connections involved in ATM allows running parallel connections within a full dedicated mode. This all allows support to multiple conversations along with eliminating the need for a bandwidth connection. There is no issue what so ever located to data bottlenecks that is most commonly found on shared networks such as Token Ring, Ethernet and FDDI.
The data transferred within an ATM network is in the form of switched virtual circuitry. This type of (SVC) connection is connected between the sender and receiver. This information gets converted in to fixed lengths of cells which gets reassembled and gets transferred at the destination.
The reliability of the ATM Network depends upon the digital lines used to ensure the integrity of the data. This ATM network doesn’t support any error correction protocol. There can be numerous amounts of re-transmissions that can take place within an ATM network.
The bandwidth of these ATM’S is dedicated and capable of supporting intensive amount of both real and non-real time applications. These are able to support all multimedia application along with high resolution computer graphics as well. The throughput provided by an ATM technology is one of the best solutions for all emerging applications like combing audio, voice along with animations as well. Although, there are various other technologies which ensure high profile bandwidth because of rich media usage but ATM is found to be most effective solution because of its fixed packet size and implementation simplicity.
These ATM is one of such technology that has got a great future within years to comes as these ATM could easily get installed over an existing network without feeling the need for going upgrading the local area network or even a metropolitan network a real example is a DSL connection from an ISP to an end user.
The Importance Of Computer Networking
Sep 5th
May be you are wondering how people can communicate through computer without having a direct connection such as cable on each other. Technology is really amazing, it can make impossible things possible with just simply following theories that make things come true.
Theories wherein, they come up with different devices to make things possible and connecting computer into one network using networking devices in able for them to communicate with each other. There are different kinds of networking device, and these devices usually function differently but its main goal is to connect one computer to another.
One main reason why computers are connected through network is to share files and information to one another. Imagine if you work in 10 storey building and you need to get files at the 10th floor and you are situated at the 1st floor.
If your computers are not connected in a network, you will probably need a storage device and go up to the 10th floor to get that files and save it on your storage device and then go down to 1st floor to save that files on your computer. If you are the owner of that company, your overhead expense everyday may not vary but the quantity of work done is will definitely not worth it paying an employee who have spend an hour getting a file from one computer to another.
If the computer are connected in a network, your company will definitely have improve its daily productivity due to the save time in getting a file from one computer to another.
This can be done through sharing files that can be transferred from one computer to another without too much effort and using a lot of office hours. This means that an employee can do a lot of work on his job with that saved time in getting a file through computer networking.

Computer Networking: Types and Advantages
Sep 1st
Computer networking is a system in which computers are interconnected via peer-to-peer connection to share data, information and resources. The computer net working is mechanized directive, which concerns itself with the communication between computer systems and devices. Computer networking is not a self-regulating discipline since it extensively derives most of its hypothetical and practical aspects from other communication technology which are based on computer science, computer engineering and information technology.
Types of Computer Networking
There are four major types of computer networking.
Local Area Network or LAN, which is a network of computers within a very small area. For example, within a one building. Its most distinctive characteristics are high data exchange rates, very small geographic area coverage, and no need for leased telecommunication lines.
Metropolitan Area Network or MAN, which is a network covering a larger area than LAN. For Example, a network of all computers within a city. A MAN may be owned and operated by a single organization but is used by a larger number of individuals and group. MAN is also used in television cable net work.
Wide Area Network or WAN, which covers a larger area than either LAN or MAN. WAN offers four connection options – leased lines, circuit switching, packet switching and cell transmit.
Wireless LAN/ WAN is the wireless alternative of the LAN or WAN which is related to telecommunication networks where the nodes are interconnected without wires or cables. Wireless networking is usually implemented using distant information transmission systems that use electromagnetic frequency for the network carrier.
Advantages of computer networking
There are following advantages of computer networking.
