CP Plus Quality Controller Interview Questions, Process, and Tips

A processor is a central processing unit that executes instructions and performs calculations in a computer system.

• A processor is the brain of a computer system, responsible for executing instructions and performing calculations.

• It is made up of various components, including the arithmetic logic unit (ALU), control unit, and registers.

• Processors can be classified into two main types: microprocessors and microcontroller...read more

A flip-flop stores one bit of information.

• A flip-flop is a basic building block of digital circuits.

• It can store either a 0 or a 1.

• It has two stable states, which represent the two possible values.

• Examples of flip-flops include D flip-flop, JK flip-flop, and T flip-flop.

A register stores a fixed number of bits, typically determined by the architecture of the computer system.

• The number of bits in a register can vary depending on the computer architecture.

• Common register sizes include 8 bits, 16 bits, 32 bits, and 64 bits.

• Registers are used to store data temporarily during processing.

• Example: In a 32-bit computer system, a register can store 32 bits of data.

The three types of addressing modes are immediate, direct, and indirect.

• Immediate addressing mode: The operand is directly specified in the instruction itself. Example: ADD #5

• Direct addressing mode: The operand is the address of the data. Example: ADD 500

• Indirect addressing mode: The operand is the address of a memory location that contains the address of the data. Example: ADD @500

A microprocessor is a small electronic device that functions as the central processing unit (CPU) of a computer.

• Microprocessors are made up of millions or billions of transistors.

• They execute instructions and perform calculations in a computer system.

• Examples of microprocessors include Intel's Pentium series and AMD's Ryzen processors.

The program counter is a register that stores the address of the next instruction to be executed by the processor.

• Program counter is a part of the processor's control unit.

• It keeps track of the execution of instructions in a program.

• The value of the program counter is incremented after each instruction is executed.

• If a branch or jump instruction is encountered, the program counter is updated to the new address.

• Example:...read more
