Answer: (b)
Solution
The act of processing data is typically done by a computer. Data processing describes how a computer manipulates data. The use of computers to carry out predetermined operations on data falls under the category of data processing. As part of the process, information is retrieved, altered, or categorised. Processing is the conversion of input data into a more understandable format. Output is the creation of the necessary information, which may be input in the future.

b) Computers provide accurate output even when input is incorrect
c) Computers are designed to be inflexible
d) All of the above
e) None of these
Answer: (a)
Solution
The benefit of using computers is that computers are very fast and can store huge amounts of data.
Computers use two different kinds of storage: a primary storage option like RAM and a secondary option like a hard drive. Storage that is internal, external, or removable can be used as secondary storage. Both benefits and drawbacks can be associated with computers. On the one hand, they give us access to the vast amount of information that is available online. We can quickly and affordably analyse enormous amounts of data thanks to them as well.

Question : 28
The first computers were programmed using
a) assembly language
b) machine language
c) spaghetti code
d) source code
e) None of the above
Answer: (b)
Solution
The computer reads and interprets a set of binary digits or bits called machine language. The only language that a computer can comprehend is machine language. One or more programming languages, such as C++, Java, or Visual Basic, are used to create computer programmes. The source code for computer programmes must be compiled because a computer cannot understand the programming languages used to create them directly. When a programme is compiled, its source code is converted into machine language, which the computer can understand.

Personal computer is
a) MC
b) SC
c) YC
d) PC
e) None of these
Answer: (d)
Solution
A personal computer is a multifunctional, reasonably priced computer intended for use by a single end user. Microprocessor technology, which enables PC manufacturers to place the entire central processing unit (CPU) on a single chip, is a prerequisite for every PC. Businesses use PCs to run databases and spreadsheets, as well as tasks like accounting, desktop publishing, and word processing. PCs are primarily used at home for multimedia entertainment, playing PC games, and other online activities. It is common to connect PCs to one another to form a network, such as a local area network, even though they are designed to be used as single-user systems (LAN).
