Computer Awareness Question 3:

On a multitasking system, a ________is a certain amount of RAM that is allocated as a temporary holding area so that the CPU can manipulate data before transferring it to a particular device.

  1. Helix
  2. Wizard
  3. Bounce
  4.  Buffer
  5. None of the above

Answer (Detailed Solution Below)

Option 1 : Helix

Computer Awareness Question 3 Detailed Solution

The correct answer is Helix.

  • Multitasking is the capability of the operating system of running several applications at the same time.
  • It is therefore deeply related to the OS capability for managing shared resources, and in particular for arbitrating conflicts resulting from resource over-commitment.
  • In a multitasking environment, the totality of the computer’s resources (memory, files, CPU time) is allocated to different applications, and they are managed in such a way that each one of them gets a share according to specific priority policies.

Key Points

  • In 1961, the LEO III emerged, which was a British computer machine that had enabled the use of multitasking in operating systems
  • The term multitasking, when paired with an operating system, refers to the users being allowed to accomplish more than one computative task, for instance.
  • Types of Multitask Operating Systems are:
    • Preemptive Multitasking.
    • Cooperative Multitasking.

Important Points

  • An Operating System does the following to carry out activities related to multitasking:
    • Initially, the user will give instructions to the operating system or to a program/application directly, and they will receive an immediate response.
    • To display this quick response, the operating system handles multitasking by “slicing” some of the processors operating capability to that program.
  • Advantages of a Multi-Task Operating System are:
    • Time-sharing.
    • Handles Multiple Users.
    • Protected Memory.
    • Efficient virtual memory.
    • Programs can run in the background.

Computer Awareness Question 4:

The term "FAT" is stands for_____.

  1. File Allocation Tree 
  2. File Allocation Table
  3. File Allocation Graph 
  4. All of the above
  5. None of the above

Answer (Detailed Solution Below)

Option 2 : File Allocation Table

Computer Awareness Question 4 Detailed Solution

The correct option is File allocation Table

Key Points 

  • The file system known as File Allocation Table (FAT) was created for personal computers. It was initially created in 1977 for use with floppy discs before being modified for use with hard discs and other hardware.
  • An operating system maintains a file allocation table (FAT) on a hard drive that shows a map of the clusters—the fundamental units of logical storage on a hard disk—in which a file has been stored.
  • This table, which is statically allocated when the drive is formatted, provides an index of the system's files. Each cluster's entry is included (a data storage area).

Additional Information 

  • Disk sector 0, or the very first sector on a disc, is where the file allocation table is found. Most operating systems still support an older style of file system storage called the file allocation table, or FAT.
  • The NTFS file system is more efficient at managing disc space and has higher disc utilization than FAT32. Additionally, NTFS read and write speeds are quicker than FAT32's.
  • File Allocation Table, also known as FAT32. FAT32 is a development of earlier file systems in which data is stored in 32-bit blocks.
