1. To differentiate primary storage from secondary storage in a computer system, which of the following statements is correct?
1. Primary storage is slower, more expensive and persistent.
2. Primary storage is faster, more expensive and persistent.
3. Primary storage is faster, less expensive and not persistent.
4. Primary storage is faster, more expensive and not persistent.
SHOW ANSWER
Explanation: Primary storage memory are Random Access Memory (RAM), registers, cache are faster, more expensive and not persistent (Volatile).
Secondary storage are hard disk drives, solid state drives, removable “USB” drives, CDs, and DVDs etc are slower, less expensive and persistent (non volatile).

2. Given below are two statements :
Statement I: Search engines are also known as web browsers.
Statement II: 189.365.250.2 is an example of a valid IP address.
A. Both Statement I and Statement II are true
B. Both Statement I and Statement II are false
C. Statement I is correct but Statement II is false
D. Statement I is incorrect but Statement II is true
SHOW ANSWER
Explanation: > Search engines (Google, Yahoo, Bing, DuckDuckgo, Baidu Internet Explorer.) and web browsers (Mozilla Firefox, Netscape Navigator, and Google Chrome.) are different > Valid IP address can not be more that 255 and 189.365.250.2 is wrong because of 365

5. Which of the following statements is true in respect of computers?
A. Software is loaded into secondary storage from RAM and is then executed by the CPU.
B. Software is loaded into RAM from secondary storage and is then executed by the CPU.
C. Software is loaded into RAM from secondary storage and is then executed by Motherboard.
D. Software is loaded into secondary storage from RAM and is then executed by the motherboard
SHOW ANSWER
Explanation: To save a programme (or something else) to a file, it is immediately saved to secondary storage, which is the hard disc. It is done by the kernel (kernel’s File management system) of the operating system.
When one run a programme, it is loaded into RAM, the computer’s main/primary memory (a small programme called the loader transfers the whole programme to RAM).
The Arithmetic Logic Unit of the CPU executes the programme instructions (in its registers like the Accumulator). To carry out the instructions, the CPU reads the values of the program’s variables from RAM and stores the results in RAM as well. The results are then sent to the output buffer stream (stdout), which prints the results (30) on the computer console/terminal.

2. (A)-(I) (B)-(II) (C)-IV) (D)-(III)
3. (A)-(IV) (B)-1) (C)-(III) (D)-(II)
SHOW ANSWER
Explanation: > E-mail is send by Formal groups of people because emails are authentic evidence in nature
> Verbal instruction can be informal in nature here as per most suitable option we can choose it
> Exchange of information between two take place in Transactional communication because in transactional sender, receiver exchanges thoughts also there are chances of barriers
> Traffic signals are non verbal and to interpret them is semantic that is study of sign processes : Semiotics
