Explanation / Answer
solution :-
Answer (2.1)
Today computers are the basic needs of any business or any individual. Mostly all the businesses are running and using the computer technology. The computer is basically used to fastening the business processes and efficient execution of the business processes. There is negligible chances of errors in the computer process execution. Therefore, computer makes the business to run and grow fast and data accuracy and standards can be achieved.
Now computers have very large memory space to store data and records of the business. By using the computer technology the data can be stored securely as well as manipulated easily. Therefore, the computer is a basic need of almost all businesses.
Answer (2.2)
The computer are used to store data and use it for business processes. When the computer is in online domain then security concerns are essential there. A computer must be secure and data must be protected from malicious attackers.
When computers are used online purposes then there should be security mechanism in order to protect the system from unauthorized access and malicious attackers. It is not necessary that all other are friendly people, there may be some malicious persons waiting for the vulnerability in the computer system. Therefore, online computer should be protected from any unauthorized access and malicious attackers.
Answer (3.1)
While using the computer the computer performance is an important aspect. The computer performance is affected by the given factors.
1) Processor speed - Processor speed affects the execution time of the processes on the computer. Processor with high speed takes less time in execution of a process.
2) Disk Drive - The access time of the secondary storage shouldbe very less in order to perform faster.
3) RAM size - The RAM size should large enough to process the data simultaneously and make the computer fast.
4) Hard drive space - The space on hard disk shouldbe large enough to store required data for long time periods. It can be help to make computer performance good.
5) GPU - The graphic processing unit should be enhanced to handle the complex image processing.
6) Defragmentation - The files should be defragmented periodically to manage the files efficiently and make the computer performance faster.
Answer (3.2)
There are some accessibility options for the special users that may havr some difficulty to use a computer system conventionally.
1) Text to speech - This feature can be useful for the people with low visibility. The text on the screen is read out by the computer system so that the person can understand it.
2) Speech recognition - This feature allows user to type the words of the user that is spoken by the user. There is no need to strike on the keyboard to type, just speak and computer gets your words and displays on the screen.
