What is a computer? - ANSWER A computer is a device that receives, stores,
and processes information
Hardware - ANSWER The physical components of a computer system
I.e. Monitor, mouse, keyboard, hard drive
Software - ANSWER The programs that execute on the computer
I.e. word processing program, web browser, Microsoft paint, etc.
Three main components of the Von Nuemann Architecture: - ANSWER 1.
Input and Output (I/O)
2. Memory (Storage of information and programs)
3. CPU (Central Processing Unit)
Input and Output - ANSWER Input:
Hardware. Keyboard, Mouse, Monitor.
Devices that allow a user to interact with the computer.
Input devices allow the computer to receive data and instructions from external
sources
Output:
Output devices allow the computer to display or broadcast the result
Memory - ANSWER Part of the computer that stores data and programs
, Modern computers are digital devices, meaning they store and process
information as binary digits (bits)
Main Memory - ANSWER Data is stored as electric signals in circuitry, used
to store active data
Memory is volatile—memory is lost when computer is turned off
EX: Random Access Memory (RAM)
Secondary Memory - ANSWER Slower but cheaper
Uses different tech:
Magnet signals on a hard disk
Reflective spots on CD
Memory is permanent—useful for storing long-term data
EX: Hard disk, flash drive, compact disk (CD)
CPU Stands for... - ANSWER Central Processing Unit
CPU - ANSWER Carries out the instructions to process information
The "brains" of the computer, responsible for controlling its inner workings
Small in size, yet very complex
Works by repeatedly fetching a program instruction from memory, and then
executing that instruction
Operating System (OS) - ANSWER Is a collection of programs that controls
how the CPU, memory, and I/O devices work together
What is the Internet? - ANSWER The internet is a vast network of computers
What is the World Wide Web? - ANSWER A collection of software that spans
the Internet and enables the interlinking of documents and resources
and processes information
