Standalone Computers and Computer Networks
Standalone Computers
A Standalone Computer is one that is not part of a network.
Standalone computers can only access data files that are stored on a storage device that is linked directly to the computer
Peripheral device used will need to be directly linked to the computer
Computer Networks
A Computer Network consists of two or more computers and peripherals that are linked together
Data files stored on a networked computer can be accessed by different network users
Networked computers can share hardware and software
Extra hardware is installed to allow each computer to link in to the network
Advantages of Networking Computers
Sharing of hardware resources
Printers, scanners and modems etc.
Improved communication between users
Intranets can be used for publishing company information
Sharing data
A common pool of data is shared among all the users, rather than each user having their own copy
The back-up of data is controlled centrally
One person can be given the responsibility for backing up files rather than relying on many individuals
Software can be shared
Software updates can be rolled out across the network much easier and can be carried out remotely.
Security
Access to the network can be restricted users who have a user ID which can only be used with a password.
Advantages of Stand Alone Computers
Reliability of performance
If a network fails, users will be unable to access the network resources
Less ICT knowledge needed
Any problems occurring will be local to the computer. With a network, problems are harder to trace.
Fewer hardware requirements
A network requires extra hardware which is difficult and expensive to install.
Security
A virus introduced on one network computer may quickly spread to the rest of the network.
