The main component of a computer that executes hardware and software operations is known as the:
a) RAM
b) Arithmetic Logic Unit
c) CPU
d) Input Device
Which of the following best describes the function of the control unit in the CPU?
a) Performs computations and logical decisions
b) Manages the flow of data between the CPU and input/output
c) Stores data temporarily
d) Stores start-up configuration data
The Arithmetic and Logic Unit (ALU) is responsible for:
a) Managing input and output devices
b) Storing configuration data
c) Performing arithmetic and logical operations
d) Displaying output
RAM is a type of:
a) Permanent memory
b) Volatile memory
c) Non-volatile memory
d) Backing storage
Which type of memory is used to store the BIOS?
a) RAM
b) ROM
c) ALU
d) Backing storage
A device that only receives data from the computer to display the output is called a(n):
a) Input device
b) Output device
c) CPU
d) ALU
Which of the following is true about secondary storage?
a) It is volatile
b) Data is lost when power is off
c) It stores data permanently
d) It can only be read from
The type of memory that retains information even without power is:
a) RAM
b) ROM
c) Program counter
d) Registers
The (a) stores basic information used by the computer system during boot-up.
A (a) is a small, high-speed storage location in the CPU used to store temporary data and instructions during processing.
The clock speed, measured in Hertz (Hz), determines how fast the (a) can execute instructions in a computer.
A (a) is a memory that is used to store data temporarily during the execution of programs.
(a) memory is non-volatile and is used to store firmware in a computer.
Secondary storage devices, like hard drives and SSDs, store data temporarily and lose the data when power is off.
True
False
RAM is a type of non-volatile memory, which means it retains data even when the power is off.
True
False
The CMOS battery is used to power the clock and store BIOS settings when the computer is powered off.
True
False
A hard drive is an example of primary memory.
True
False
The control unit of the CPU uses the clock to ensure that all operations happen in the correct sequence.
True
False
