Explanation

• Machine Language is the lowest-level computer language, written entirely in binary code (0s and 1s).
• It is directly understood by the computer’s CPU without any translation.
• All higher-level languages (like C, Pascal, Basic) are converted into machine language before execution.

Explanation

• Compiler Function: Converts high-level language into machine language.
• Output: Produces an object file (.obj / .exe) after compilation.
• Examples of Languages Using Compiler: C, C++, Java (uses compiler + JVM).

Additional information:

• Compiler: Translates whole program at once.
• Interpreter: Translates line by line.

Explanation

• A physical connection between the microprocessor memory and other parts of the microcomputer is known as an address bus.

Additional information:

• Address Bus carries the addresses of memory locations or I/O devices.
• Data Bus carries actual data between the CPU, memory, and other components.
• Control Bus carries control and timing signals.

Explanation

• RAM (Random Access Memory) is installed on the motherboard of a computer.
• RAM is usually placed in DIMM slots on desktop motherboards.
• RAM temporarily stores data and programs currently being used by the CPU.
• RAM is volatile memory, meaning its contents are lost when power is turned off.

Explanation

• In the ALU (Arithmetic Logic Unit), arithmetic and logical operations required during instruction execution are performed.
• ALU performs arithmetic operations such as addition and subtraction.
• It also performs logical and comparison operations.

Additional information:

• The Control Unit (CU) directs and coordinates the execution of instructions.
• Main Memory stores programs and data currently being used.
• The CPU consists mainly of the ALU, Control Unit, and registers.
