Question Discussion & Solution

Below are a few types of Unconditional Control Structures

The “break” Statement

A break statement terminates the execution of the loop and the control is transferred to the statement immediately following the loop. 

Syntax : Jump-statement;  break;

The “continue” Statement

The continue statement is used to bypass the remainder of the current pass through a loop.

 Syntax : Jump-statement;  Continue;

The “goto” Statement

C supports the “goto” statement to branch unconditionally from one point to another in the program.

Syntax :

goto label;
.............
.............
.............
label:
statement;

Return Statement :

The return statement terminates the execution of a function and returns control to the calling function. Execution resumes in the calling function at the point immediately following the call.

 Syntax : Jump-statement: return expression;

 Therefore answer is goto statement i.e, Option 4 

All given numbers are cube except 400. 400 is a square of 20.

The correct answer is Hard Disk.

• In a typical desktop computer,  Hard disk memory sizes would be the largest.
• had a capacity of 1 to 8 terabytes, with the largest-capacity drives reaching 20 terabytes (single-disk drives, "dual" drives are available up to 24 TB).
• Smaller, laptop internal 2.5-inch drives, are available up to 5 TB.
  • Register> RAM> Cache> Hard disk.

​​Key Points

• RAM 
  • RAM is a hardware element where the data being currently used is stored.
  • It is a volatile memory.
  • Two types of RAM are
    • Static RAM, or (SRAM) and
    • Dynamic RAM, or (DRAM).
• Register
  • A register holds instructions or data that the processor is working on or will be working on shortly.
  • They form part of the processor and are capable of holding only one item at a time.
• Cache 
  • Cache memory is an area in the computer where codes and instructions are stored.
• Hard disk
  • A hard disk drive is an electromechanical data storage device that stores and retrieves digital data using magnetic storage.

Additional Information

• There are four major storage levels on the computer:
  • Internal – 
    • Processor registers and cache.
  • Main –
    • The system RAM and controller cards.
  • On-line mass storage –
    • Secondary storage.
  • Off-line bulk storage –
    • Tertiary and Off-line storage.

The correct answer is Deforestation.

• Deforestation is not related to conservation of land resources.

Key Points

• The felling and clearing of forest cover or tree plantations to accommodate agricultural, industrial or urban use is Deforestation.
• Deforestation can also be seen as removal of forests leading to several imbalances, both ecologically and environmentally.
• According to the Global Forest Resources Assessment 2020 (FRA 2020) report, the rate of forest loss has declined in the period of 1990-2020.
• The world’s total forest area is 4.06 billion hectares (bha), which is 31% of the total land area.

Additional Information

• The FRA is released by the United Nations Food and Agriculture Organization (FAO).
• Restriction on overgrazing is done to reduce Negative effects of grazing which include overgrazing, increased soil erosion, compaction and degradation, deforestation.
• Land reclamation is the process of creating new land from oceans, seas, riverbeds or lake beds.
• Regulated use of fertilizer controls the movement of water and nutrients within the plant.
