Question Discussion & Solution

The correct answer is 2 * 1024 * 1024 Bytes.

• One thousand and twenty-four kilobytes (1024 KB) is equal to one megabyte (1 MB), where 1 MB is 10242 bytes.
  • ​So 2 Mb equals to 2 * 1024 * 1024 Bytes.

Key Points

• The cache memory
  • The cache memory is located very close to the CPU, either on the CPU chip itself.
  • It can be located on the motherboard in the immediate vicinity of the CPU.
  • So data can be read from it (and written to it)more quickly than with normal RAM. 

Additional Information

• Cache
  • A cache is a special storage space for temporary files that makes a device, browser, or app run faster and more efficiently. 
• There are three general cache levels:
  • L1 cache, or primary cache:
    • It is extremely fast but relatively small and is usually embedded in the processor chip as CPU cache.
  • L2 cache, or secondary cache:
    • It ​is often more capacious than L1.
  • Level 3 (L3) cache 
    • It is a specialized memory developed to improve the performance of L1 and L2.

The correct answer is Indicator.

Key Points

• Indicators are substances that show a change in colour when brought in contact with acids and bases.
• The most common indicator used in the laboratory is Litmus.
• Litmus is extracted from lichens.

Additional Information

• A promoter is a sequence of DNA needed to turn a gene on or off.
• A neutralizer is a substance used in the neutralization of acidic water.
• Neutralization is a chemical reaction in which acid and a base react quantitatively with each other to form water and salt.
• A catalyst is a substance that speeds up the rate of a chemical reaction but is not consumed during the reaction.
