E. A and C

2. What is a sequence of booting up an Operating System?

A. User Login  Bootstrap Programs  Operating System Kernel  Other Programs

B. Operating System Kernel  Bootstrap Programs  User Login  Other Programs

C. Bootstrap Programs  Operating System Kernel  User Login  Other Programs

D. User Login  Other Programs  Operating System Kernel Bootstrap Programs

3. Which one of the following is NOT a storage hardware?

A. Solid State Disk

B. Random Access Memory

C. Registers

D. Optical Fiber

4. Which one of the following is true about caching in computer system?

A. A caching is to transfer data between various storage devices at high speed

B. Information saved in a faster storage device to serve the future request faster

C. Important data are saved in backup disk for future retrieval if original is corrupted

D. Some data are saved in cloud so that it can be accessible from many places

Answer 1

1) E. A and C

An operating system is a system software that manages computer hardware, software resources, and provides common services for computer programs.

It is not a programming language for writing code.

The operating system acts as the manager of the resources, decides between conflicting requests, controls execution of programs etc.

2) C. Bootstrap Programs  Operating System Kernel  User Login  Other Programs

Bootstrap programs are the initial program to run when a system is powered up.

It then finds the operating system kernel on disk and then loads the kernel into memory.

Once the booting is performed, user can login and access other programs.

3) D. Optical Fiber

Optical Fiber is the technology associated with data transmission using light pulses travelling along with a long fiber. it is NOT a storage hardware.

  A register is a temporary storage area built into a CPU.

RAM(Random Access Memory) is a hardware device that allows information to be stored and retrieved on a computer.

4) B. Information saved in a faster storage device to serve the future request faster

A cache is a hardware or software component that stores data, so that future requests for that data can be served faster.

  Caching is a technique used by computers to store data that is likely to be used soon, in a faster form of memory.
