Explanation

A soft copy is an electronic version of data, such as a file or document, stored digitally.

Soft copies are typically viewed on a computer or mobile device screen.

Explanation

Marcian Edward "Ted" Hoff Jr. is one of the inventors of the microprocessor.

In 1980, Hoff was named the first Intel Fellow, which is the highest technical position in the company.

He stayed in that position until 1983 when he left for Atari.

Explanation

A programmer is primarily focused on coding and developing software applications based on specific requirements provided by users or organizations.

Additional Points:

• Programmers are skilled in programming languages like Python, Java, C++, etc.
• They often work on debugging, testing, and optimizing code to ensure it runs efficiently.

Explanation

Binary numbers are made up of only two digits: 0 and 1.

Only 1001 consists solely of 0s and 1s, making it a binary number.

Explanation

A computer can perform any task that can be broken down into a series of logical, step-by-step instructions.

This is because computers process tasks by following a series of instructions or steps.

Explanation

A device driver is a program containing instructions that enable a computer to communicate and operate a specific hardware device.

A device driver is a program that contains instructions to operate and control a specific device.

Explanation

A number system that has eight different symbols to represent any quantity is known as Octal.

The Octal number system uses digits from 0 to 7.

It is often used in computing as a simpler alternative to binary representation.

Explanation

In computer science, the levels of representation are typically shown from high-level to low-level as:

• High-level: Software (e.g., C++, COBOL, JAVA)
• Low-level: Hardware (e.g., machine code, assembly language)

Explanation

The CPU (Central Processing Unit) executes instructions and performs calculations.

This making it the primary component responsible for processing data in a computer.

Explanation

The Control Unit (CU) is the part of the computer's central processing unit (CPU) that executes instructions.

It retrieves instructions from memory, decodes them, and then carries out the required actions.

The Control Unit manages the flow of data between different parts of the computer, including the Arithmetic Logic Unit (ALU) and Main Memory.
