Group 2 Flashcards
It is considered as the “Brain of the Computer”.
It is the main component of a computer that performs most of the processing tasksm
Central Processing Unit
(CPU)
The first developed CPU
Intel 4004 in 1971 by team led by Ted Hoff
It centralised the processing of data instructions, management, and control of peripheral devices
Central Processing Unit
(CPU)
These pins transfer signals (such as data, power, and control signals) between the CPU and other components of the Computer.
Gold pins
A flat board that holds and connects electronic components using copper traces.
Black PCB (Printed Circuit Board)
A tiny piece of silicon that contains many electronic components like transistors and diodes.
Silicon chip (Integrated Circuit)
A component that limits the flow of electric current.
Resistors
A component that stores and releases electrical energy.
Capacitors
Processing and executing instructions:
●Fetch
●Decode
●Execute
Managing System Resources:
●Input/output devices
●Memory management
●Interrupt handling
Refers to how fast a CPU can execute instructions, measured in Hertz (Hz). Modern processors usually operate in Gigahertz (GHz), meaning billions of cycles per second.
Clock speed
Best for single-core tasks, making it ideal for gaming and certain professional applications.
Intel
Excels in multi-core performance, making it great for multi-threaded tasks like video editing and rendering.
AMD
Components of CPU
●Control Unit
●Arithmetic Logic Unit (ALU)
●Memory Management Unit
●Register
Responsible for managing data flow and the execution of instructions within the computer system
Control Unit
What cycle does the Control Unit use to manage data flow.
Fetch-decode-execute cycle
It executes calculations using binary numbers and manipulates them using logic gates.
It receives data from registers within the CPU
Arithmetic Logic Unit (ALU)
These components handle memory-related tasks, such as managing the CPU and RAM interaction.
Memory Management Unit
These are small, high speed memory storage locations within the CPU. They hold data that the CPU is currently working on and facilitate quick access data.
Register
It provide faster access times than other memory levels like RAM or cache memory
Quicker than cache memory but limited storage, typically measured in kilobytes.
Register
