Lecture 1 slide Flashcards
(11 cards)
What does hardware consist of?
The physical elements in a computer system
Examples include the monitor, mouse, external storage, and keyboard.
What is the role of the central processing unit (CPU)?
Performs program control and data processing
It is essential for executing instructions and managing resources.
Name two types of storage in a computer system.
- Primary Storage
- Secondary Storage
Primary storage is temporary and requires power, while secondary storage is persistent.
What are examples of secondary storage devices?
- Hard disk
- Flash drives
- CD/DVD drives
These devices provide slower, less expensive storage.
What is the function of input/output devices?
Allow the user to interact with the computer
Examples include a mouse, keyboard, printer, and screen.
What are the two components of the CPU?
- Control Unit
- Arithmetic Logic Unit
Each component has distinct roles in processing and control.
What does the control unit do?
Directs operation of the processor
Manages all computer resources and controls communication between devices.
What is the role of the arithmetic logic unit?
Contains circuitry to perform calculations and comparisons
It acts as the workhorse of the computer, executing tasks directed by the control unit.
Fill in the blank: Primary storage is composed of _______.
[memory chips]
These are electronic circuits that store data temporarily.
What is the characteristic of secondary storage?
Slower, less expensive, and persistent
Data persists without electric power.
Where are data and programs located when not in use?
In secondary storage
They are loaded into memory when the program is executed.
