What is a computer?
An electronic device that accepts data, processes it, stores it, and produces output based on instructions.
What are the four basic functions of a computer?
Input, Processing, Output, Storage.
What is input?
The process of entering data into a computer.
What is processing?
The action the computer takes to transform input into meaningful information.
What is output?
The result produced by the computer after processing data.
What is storage?
The ability to save data and information for future use.
What is the processor also known as?
The Central Processing Unit (CPU).
What is a processor?
The primary component of a computer that executes program instructions and performs operations like arithmetic, logic, control, and input/output.
What are the components of the CPU?
Control Unit, Arithmetic and Logic Unit, Registers.
Where is the processor located?
On the motherboard.
What does the processor do?
Interprets and carries out instructions used to operate the computer.
What operations can the processor perform?
Addition, subtraction, multiplication, and division.
What are the four basic functions of the processor?
Fetch, decode, execute, store.
What is the Control Unit (CU)?
The part of the CPU that directs operations and coordinates other components.
What does the CU do?
Fetches instructions, decodes them, and sends signals to execute them.
What is the Arithmetic Logic Unit (ALU)?
The part of the CPU that performs all arithmetic and logical operations.
What does the ALU do?
Handles operations such as addition, subtraction, comparisons, and logical decisions.
What are registers?
Small, high-speed storage areas in the CPU that temporarily hold data and instructions.
What do registers provide?
Fast access to data being processed.
What is the bus?
A circuit that transfers data and instructions between CPU components.
What is clock speed?
The rate at which a processor executes instructions, measured in Hertz (Hz).
What does a higher clock speed mean?
Faster processing of instructions.
What are processor cores?
Independent processing units within the CPU that can execute instructions simultaneously.
What is a dual-core processor?
A processor with two cores.
