Capabilities and Limitations of computer

Computer is a device, which is capable of doing almost all the works, which can be programmed by the user. But there are some functions, which are impossible for a computer to perform. Following are some of the capabilities and limitations of computer:

Capabilities

Computer can do jobs with 100% accuracy and in a very fast speed in comparison to any other devices or human.
It is possible to show and do the things, which are impossible for humans.
Computer provides faster and cheaper communication with the user of various communication technologies.
It can perform almost all the works but for any purpose, user must provide proper program and necessary hardware.

Limitations

Computer is dull machine. It doesn't have intelligence on it. So, whatever i9t does, that is with the help of programs and devices developed by human. If such assistances are not provided, it will not be able to perform the simple of the simplest works, too.
If any error occurs in its structure or circuitry, then the output (result) given by it is wrong which is very hard to tackle. It can't distinguish between the good and bad inputs and outputs in comparing to human. So, it is often called 'idiot servant'.

Define LAN and WAN

. Local Area Network (LAN) A LAN is a network that is used for communicating among computer devices, usually within an office building or home. LAN’s enable the sharing of resources such as files or hardware devices that may be needed by multiple users • • Is limited in size, typically spanning a few hundred meters, and no more than a mile. Is fast, with speeds from 10 Mbps to 10 Gbps. Requires little wiring, typically a single cable connecting to each device. Has lower cost compared to MAN’s or WAN’s. LAN’s can be either wired or wireless. Twisted pair, coax or fiber optic cable can be used in wired LAN’s. Advantages of LAN : The data is transferred at an extremely faster rate in local Area Network. Local area network (LAN) provides higher security. Disadvantages of LAN : Initial cost of installing local area network is quite high. Unauthorized user can access critical data of an organization in case LAN ad...
