15. What is not true about GNU operating system? [Chhattisgarh P.C.S. (Pre) 2021]

Correct Answer: (d) It is not compatible with Unix
Solution:

GNU is an extensive collection of free software, which can be used as an operating system or can be used in parts with other operating systems. GNU stands for "GNU's Not Unix," chosen because GNU's design is Unix-like, but differs from Unix by being free software and containing no Unix code.

Development of the GNU operating system was initiated by Richard Stallman while he worked at MIT Artificial Intelligence Laboratory. Richard Stallman made the initial announcement of the GNU Project in September, 1983. The GNU operating system is upward-compatible with Unix. Hence, statement of option (d) is not true.

17. The memory of the computer is measured by- [U.P.P.C.S. (Mains) 2006]

Correct Answer: (a) Bits
Solution:

The main function of the computer memory is to store data and information. Bit or binary digit is the smallest unit of computer memory. All computers work on a binary numbering system, i.e. they process data in ones and zeros. This 1 or 0 level of storage is called a bit.

Correct Answer: (a) 0 and 1
Solution:

Binary describes a numbering scheme in which there are only two possible values for each digit, 0 and 1. The term also refers to any digital encoding/decoding system in which there are exactly two possible states.

In digital data memory, for storage, processing, and communication, the 0 and 1 values are often called as "low" and "high" respectively.
