The Program Counter (PC) stores the address of the next instruction, ensuring the CPU knows where to fetch the next operation from memory.

The Control Unit is responsible for directing the operation of the processor, interpreting instructions, and coordinating the flow of data between the CPU and other hardware.

The Accumulator is a register in which intermediate arithmetic and logic results are stored.

CPU clock speed represents the number of clock cycles a CPU can execute per second, measured in Gigahertz (GHz).

The MAR holds the memory location of data that needs to be accessed, read from, or written to in the main memory.

The Flag or Status Register contains status bits that represent the outcome of the most recent ALU operation.

The ALU performs both arithmetic operations (addition, subtraction) and logical operations (AND, OR, NOT) on binary data.

Once fetched from memory, the instruction is stored in the Instruction Register (IR) while the Control Unit decodes it.

A bus is a communication pathway or subsystem that transfers data, addresses, or control signals between various components inside a computer.

The Memory Buffer Register (MBR), also known as the Memory Data Register (MDR), acts as a buffer to hold data moving between the CPU and memory.

The Instruction Register holds the actual opcode of the instruction currently being processed by the Control Unit.

Pipelining is a technique where multiple instructions are overlapped in execution, allowing the CPU to work on different stages of several instructions simultaneously.

The Control Unit sends signals through the Control Bus to interact with memory and I/O devices to initiate the fetch sequence.

The Accumulator is a general-purpose register that acts as the primary location for data being processed by the ALU.

Giga (G) represents one billion. Therefore, 3.5 GHz equals 3.5 billion cycles per second.

Register size (e.g., 32-bit or 64-bit) defines the word size of the CPU, determining how much data it can handle in a single operation.

The XOR (Exclusive OR) operation returns 0 if two bits are identical and 1 if they are different, making it ideal for equality checks.

The Control Unit interprets instructions and generates control signals that tell the ALU, registers, and memory how to execute the instruction.

Overclocking is the practice of increasing the clock frequency of the processor beyond its factory specifications to improve performance.
