According to the book, the function of the control unit is to perform logical operations. (Note: Generally, logical operations are the work of the ALU, but option 3 is considered correct in the book).

A software package that provides advertisements is called Adware.

The Arithmetic Logic Unit is primarily responsible for performing calculations in a computer.

Instruction is an example of a software approach.

Arithmetic Operations include addition, subtraction, multiplication, and division.

Integrated circuit (IC) chips used in computers are made of semiconductor materials, primarily silicon.

Program Counter (PC) is a register present in the CPU, which contains the addresses of the next instruction to be executed from memory.

The Control Unit is the part of the computer's processor that directs all operations. It tells the memory, ALU, and input-output devices how to follow the instructions of a program.

The main advantages of Component Object Model (COM) include low cost and readability.

The task of the Job Scheduler is to select processes from the job pool and prepare them for execution.

Clock speed and cache memory have the most impact on processor speed, while system bus speed has relatively less impact.

Oracle is a database software, developed by Oracle Corporation for Relational Database Management System (RDBMS).

When new data is written into a register at the software or hardware level, the previously existing data is overwritten (erased).

The main basis of computer operation is processing, which converts input into output.

Software is a set of instructions, hence it is also called a program.

The assessment of a computer's performance is based on the number of instructions executed by its microprocessor in one second. Its basic unit is 'Hertz', while larger units are called Kilohertz, Megahertz, Gigahertz respectively. Currently, Gigahertz class microprocessors are generally being used.

The full name of CPU is 'Central Processing Unit'. It is called the brain of the computer and includes the Control Unit, Memory, and Arithmetic Logic Unit.

'Expansion Slots' on the motherboard provide the capability for the computer to add new hardware (like graphics cards, sound cards, etc.) in the future.

Magic Lantern, V.C.R, and Overhead Projector are examples of hardware technology.

The operations executed in the $CPU$'s internal registers are called Micro-operations.
