Types and Advantages of computer networks
Dec 6th
You must know that a network consists of more than one commuter that is linked in order to share resources. It is advantageous in that you can exchange files; allow electronic communications, even printers and CD-ROMs). There are three basic types of network that are normally used:
1. Local Area Network (LAN) 2. Metropolitan Area Network (MAN) 3. Wide Area Network
Local Area Network is confined to a small area and is generally limited to a geographical area about a mile apart to other computers. The configuration of LAN consists of software that controls the network and also the software that is shared by other computers that are attached to the network. It consists of a file server, a workstation and cables.
Metropolitan Area Network covers larger geographic areas and covers cities. They are used by local libraries and Government agencies to connect to citizens and private industries.
Wide Area Network connects larger geographic areas all over the world.
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.
Types Of Computer Hardware: Basics 101c
Jan 2nd
The personal computer consists of multiple computer hardware or multiple devices linked together to create a whole working machine. Some of the hardware are external such as keyboards, printers and mouse that is connected via cable or other methods. These hardware need to be installed via a software program before it can run. They increase the efficiency of the personal computer, and do tasks such as business, design, entertainment and more. Here are the main types of computer hardware that you can buy for your PC.
1. Hard drive – also called hard disk, it is the permanent storage space that stores all information and applications of the computer, retaining the space even when it is turned off.
2. Motherboard – Considered as the most important types of computer hardware. The motherboard houses the microprocessor, providing the necessary sockets and slots that connect to all other types of computer hardware. Thus the motherboard serves as the ‘mediator’, a channel that allows the components to work together and walk to each other, making it a whole and completely working unit.
3. RAM – short for Random Access Memory. It is the memory used to process applications. RAM is lost when the computer is turned off.
4. ROM – short for Read Only Memory. It serves as memory for storage of programs.
5. Storage Devices – External storage devices like CDs, DVDs, USB flash drives are important as removable storage devices that you can take from one personal computer to another.
6. Power Supply Unit (PSU) – this converts the AC power to low voltage DC power, integral for the internal components of the PC.
7. Sound Card – responsible for the PC’s audio input and output, necessary for games, music and other multimedia programs.
A lot of Elements of some types of computers

For some men and women, a laptop which is pre constructed just isn’t the answer to what they want as well as have to have. A graphic designer will need some thing that takes into account pc elements which can be heavily geared toward graphics, for example a much more complete featured graphics minute card plus a vast amount associated with Ram, while the games tester may well want a thing that will offer you a powerful three or more dimensional card and also a far far more powerful audio tracks setup.
This means that employing a service including the well-liked firms to develop your personal machine may perhaps cost a large amount much more in your Computer. Creating your own laptop retains your costs down and improves it can be that you simply get one thing which is built to your specifications and has the operating technique that you would like, rather than the 1 which will be auto-installed onto their brand of laptop or computer.
Developing a personal computer from scratch is among the best and unique hobbies that you can take up. They have the added benefit of obtaining you precisely what you would like from your laptop or computer and offering you the chance to modify every single aspect with the method.
Nearly all computers that you simply will acquire offer you you a minimal level of things like Ram, harddrive space and Dvd movie or Cd Roms. Creating your own personal Pc or even customized laptop or computer will certainly net you the exact items that you simply want and want and get you the exact operating program that you want. It’s usually the best solution to give you the nearly all bang in your processing dollar.
Types of Computer Networks
Aug 25th
There are different types of Computer Networking that you may need for your home or office. To begin with you have the option of a wired or wireless computer network. These types of networks differ. A wired computer network will have copper or fiber optic cabling running between computers while a wireless network uses radio waves and/or microwaves to maintain communication channels.
A client/server network works by using client devices, typically PCs with network software applications installed that request and receive information over the network. The server device will usually store files and databases and includes more complex applications like Web sites. These devices often feature high-powered central processors, more memory and larger disk drives than the client devices. Two examples of client-server systems include Web browsers and servers.
In addition to these types of networks there are also types of area networks. These are categorized by their scope or scale. Some area network types include:
• LAN – Local Area Network
• WAN – Wide Area Network
• WLAN – Wireless Local Area Network – a LAN based on WiFi wireless network technology
• MAN – Metropolitan Area Network – a network spanning a physical area larger than a LAN but smaller than a WAN, such as a city. A MAN is typically owned an operated by a single entity such as a government body or large corporation.
• CAN – Campus Area Network – a network spanning multiple LANs but smaller than a MAN, such as on a university or local business campus.
• Storage Area Network – connects servers to data storage devices through a technology like Fibre Channel.
• System Area Network – links high-performance computers with high-speed connections in a cluster configuration. Also known as Cluster Area Network.
