The correct answer is ROM.

Key Points

• ROM
  • Read-Only Memory is a ROM in a computer.
  • Read-only memory is a storage medium that permanently stores data on computers and electronic devices.
  • The data stored in these chips is nonvolatile i.e. it is not lost when power is removed.
  • There are five basic ROM types:
    • ROM: Read-Only Memory.
    • PROM: Programmable read-only memory.
    • EPROM: Erasable programmable read-only memory.
    • EEPROM: Electrically erasable programmable read-only memory.
    • Flash memory: Flash memory, a type of EEPROM that uses in-circuit wiring. 
  • BIOS uses Flash memory.

Additional Information

• Register
  • The smallest and fastest memory of a computer is registered memory located in the computer's central processing unit(CPU).
  • It generally stores the most used instructions, data, etc. which are to be used by CPU.
  • Control Unit is part of the CPU.
  • It advises the input and output devices, and computer memory on how to respond to the instructions sent to the processor.
• RAM
  • It stores data that the computer needs to use temporarily. So it is faster than the secondary storage devices. It is a volatile memory i.e. the data disappear from it when the power is off.
  • It is known as the Read-Write Memory. i.e. the user can write information into RAM and read information from it.
  • It is called random access since any memory location can be accessed randomly for reading and writing. The access time is the same for each memory location.
  • It is usually called “temporary” memory, which means that when the system is shut down, the memory is lost.
• Cache
  • A cache memory is used by the central processing unit of a computer to reduce the average cost time or energy to access data from the main memory.
  • Generally Cache memory is logically positioned between CPU and main memory.

Primary Sector as the Largest Employer
The assertion states that the primary sector is the largest employer, while the reason provided is that it includes occupations related to man's natural environment such as farming, animal rearing, and mining. Let's analyze whether both the assertion and the reason are true and if the reason is a correct explanation for the assertion.
A: Both A and R are true and R is the correct explanation of A.
- The primary sector refers to the sector of the economy that is involved in the extraction and production of natural resources. It includes activities such as agriculture, forestry, fishing, mining, and quarrying.
- The primary sector is indeed the largest employer in many countries, especially in developing economies where agriculture plays a significant role in the economy.
- The reason provided also aligns with the definition of the primary sector, stating that it involves occupations related to man's natural environment like farming, animal rearing, and mining.
- The reason correctly explains why the primary sector is the largest employer, as these activities require a significant workforce due to their nature and scale.
Therefore, both the assertion and the reason are true, and the reason is indeed the correct explanation of the assertion.
Hence, the correct answer is A: Both A and R are true, and R is the correct explanation of A.

- Given Codes:
- PAINT = 74128
- EXCEL = 93596

- Analysis:
- Each letter is represented by a single digit in the code.

- Mapping:
- P -> 7
- A -> 4
- I -> 1
- N -> 2
- T -> 8

- Applying the same logic to ACCEPT:
- A -> 4
- C -> 5
- E -> 5
- P -> 7
- T -> 8

- So, the code for ACCEPT is 455978, which corresponds to option A.

–12, –6, 0, 6,…
Let a(1) = -12, a(2) = -6, a(3) = 0, a(4) = 6
First relational d,
a(2) – a(1) = -6 – (-12) = 6
Second relational d,
a(3) – a(2) = 0 – (-6) = 6
Third relational d,
a(4) – a(3) = 6 – (0) = 6
all the d are equals to each other, hence
d = 6.

Direct Method of Deadlock Prevention

A direct method of deadlock prevention is to prevent the occurrence of circular waits. Here is a detailed explanation:

Mutual Exclusion:
- Mutual exclusion refers to the condition where a resource can only be allocated to one process at a time.
- Preventing mutual exclusion is not a direct method of deadlock prevention because it may not always be feasible to allow multiple processes to access a resource simultaneously.
Hold and Wait:
- Hold and wait refers to the condition where a process holds a resource while waiting for another resource.
- Preventing hold and wait is not a direct method of deadlock prevention because it may not always be possible for a process to acquire all the required resources at once.
Circular Waits:
- Circular waits refer to the condition where a set of processes form a circular chain, with each process in the chain waiting for a resource held by the next process in the chain.
- Preventing circular waits is a direct method of deadlock prevention as it eliminates the possibility of a deadlock occurring due to circular dependency.
No Preemption:
- No preemption refers to the condition where a resource cannot be forcibly taken away from a process.
- While preventing no preemption can help in avoiding certain deadlocks, it is not a direct method of deadlock prevention as it does not eliminate the possibility of circular waits.
Therefore, the correct answer is C: Circular waits. Preventing the occurrence of circular waits is a direct method of deadlock prevention.

In the pre-independence period, most manufacturing units were located in places suitable for overseas trade like Mumbai, Kolkata, Chennai, etc. The reason was to reduce the cost of ​manufacturing (due to low transportation costs to bring-in raw materials) and transportation from manufacturing units to seaport.

The magnitude of the population increase is measured by the population growth rate.
Explanation:
- Population growth rate is the measure of how fast a population is growing over a specific period of time. It is usually expressed as a percentage.
- The population growth rate takes into account both birth rate and death rate as they directly impact the change in population size.
- The birth rate refers to the number of births per 1,000 individuals in a population within a specific time period.
- The death rate refers to the number of deaths per 1,000 individuals in a population within a specific time period.
- The difference between the birth rate and the death rate gives the natural increase in population, which contributes to population growth.
- However, the population growth rate also takes into consideration other factors such as migration, which can further impact the overall population increase or decrease.
- Therefore, the most accurate measure of the magnitude of population increase is the population growth rate.
- Other options, such as birth rate and death rate, are important components in understanding population dynamics but do not directly measure the overall magnitude of population increase.

A dot matrix printer is a type of printer that uses a matrix of small pins to create characters or images on paper. Let's analyze each statement to determine the correct answer:
i) Prints an entire line at a time: This statement is incorrect. A dot matrix printer prints one character at a time by striking an ink-soaked ribbon against the paper. It does not print an entire line at a time.
ii) Is a non-impact printer: This statement is incorrect. A dot matrix printer is an impact printer because it uses physical force to create the characters. The pins strike the ribbon, which transfers ink to the paper, resulting in the printed output.
iii) Allows multiple copies to be taken at a time: This statement is correct. Dot matrix printers have the ability to create multiple copies simultaneously. This is achieved by using carbon paper or carbonless paper, which allows the impact of the pins to transfer the image to multiple layers of paper.
iv) Prints one character at a time: This statement is correct. Dot matrix printers operate by individually striking pins against an ink-soaked ribbon to create characters. Each pin represents one dot, and the combination of dots forms the characters or images on the paper.
Based on the analysis above, the correct answer is C: iii and iv. A dot matrix printer allows multiple copies to be taken at a time and prints one character at a time.

The logic followed here is:

In figure 1:

32 = (2 + 2) × 8

4 × 8

32

In figure 2:

24 = (3 + 1) × 6

4 × 6

24

Similarly,

In figure 3:

45 = (4 + ?) × 5 

4 + ? = 9

? = 9 - 4

? = 5

Hence, the correct answer is "5".
