Benefits of network: A network is where two or more computers are connected together to share their information each other.
There are some advantage and disadvantages of network:
Advantages
1. Peripherals such as printers can be used shared amongst many different users.
2. Terminals are cheaper than standalone PCs.
3. Software can be shared amongst different users.
4. Communication across the network is cheap and fast.
5. Files can be stored on a central computer (the file server) allowing data to be shared throughout an organisation.
6. You can communicate each another with a network
7. Save of time and money
Disadvantages
1. Cabling is expensive to install and replace.
2. A fault with a server will prevent the whole network from the work.
3.Security measures are needed to restrict access to the network.
Network hardware and software componentsSome hardware components for LANs need network are set up on the system. Just as in any type of computer system, the main hardware components required for LANs are the hard disk, monitor and key board.
There are some other components and technologies:
- Network cards
- Work stations
- Server
- Modems
- Board bands technologies
- Peripherals
- Routers
- Hubs and switches
- Uninterruptible
Network cards: A network card is a piece of computer hardware design to allow computers to communicate over a computer network.
Workstation: A workstation is a computer that is linked to a network. Workstation are used to able to access the network can use the hardware and software of the computer.
Servers: server is an application programme that’s accepts connections in order to service request by sending back responses.
Modem: A modem is required if data has to be transferred between two computers over links, such as telephone lines etc. when the digital signal leaves the computer , a modem convert it to analogue. A modem at receiving end reconverts the signal to digital before passing it to the second computer.
Broadband technologies: Broadband is becoming more popular as a network connection. Most broadband technologies are working through a digital signal so, its also very fast way of connecting to a network. The most commonly available broadband technologies are ISDN and ADSL:
ISDN: Stands for (integrated service digital network) Convert voice to digital and sends data and voice over the standard telephone system.
ADSL: Stand for (asynchronous DSL) which just mean higher rates in one direction i.e. for downloading data.
Peripherals:A peripherals is a piece of computer hardware that is added to a host computer, i.e. any hardware except the computer, in order to expand its abilities. More specifically, the term is used to describe those devices that are optional in nature, as opposed to hardware that is either demanded or always required in principle.
