Operating System Activity

What is the role of the bootstrap program when a computer is switched on?

• Manage resource utilization

• Initiate the start-up procedures

• Access flash memory

• Load the operating system into main memory

Why is the start-up of tablets and mobile phones almost instantaneous?

• They use RAM for main internal memory

• They have a faster CPU

• They have a more efficient operating system

• They have a larger storage capacity

Which part of flash memory is read-only and contains the operating system?

• Part 1

• Part 2

• Neither part

• Both parts

Where are apps executed and where is data currently in use stored?

• Flash memory

• ROM chip

• RAM

• Hard disk/SSD

What is the purpose of resource management in an operating system?

• To maximize CPU utilization

• To minimize memory usage

• To optimize I/O operations

• To improve software compatibility

What does the DMA controller do?

• Allows hardware to access the main memory independently of the CPU

• Manages input/output operations

• Handles interrupt signals

• Carries out background utilities

Which component of the operating system is responsible for communication between hardware, software, and memory?

• Bootstrap program

• DMA controller

• BIOS

• Kernel

What is one of the most important tasks of an operating system?

• To carry out virus scanning

• To manage memory and storage devices

• To simplify hardware interfaces

• To provide a graphical user interface

What is the purpose of using GUI interfaces instead of CLI?

• To simplify the saving and retrieving of data

• To optimize CPU utilization
