Study Notes
- A computer is any device that accepts input, stores it, processes the stored input, and provides an output.
- An unconventional example of a computer is a printer because it can receive images from a computer, process them, and output images on pages.
Input vs. Output
- An input device connects to a computer and sends data into it.
- An output device connects to a computer and receives incoming data.
- Data sent to the computer by an input device for processing is reproduced or displayed by the output device.
- Examples of input devices: mouse, keyboard, microphone, touchscreen, scanner.
- Examples of output devices: printer, screen, speakers.
CPU Tasks
- The CPU interprets, processes, and executes instructions.
- Memory Management Unit: Tells you what is stored where
- Control Unit: Regulates what is on and what is off
- Arithmetic Logic Unit functions: addition, subtraction, comparisons, etc.
Primary vs. Secondary Storage
- Primary storage (RAM and/or ROM) is required for a computer to function.
- RAM: Random Access Memory.
- ROM: Read-Only Memory, which includes BIOS.
- Secondary Storage: Hard drives, USB keys, and CDs are not required, but can be used for data storage
Computer Software
- Computer software is activated by electricity.
- Computer software constitutes the data and instructions that tell the hardware what to do and when.
- Together, hardware and software, make a computer.
Computer Hardware vs. Software
- Hardware is physical components such as monitors, keyboards, microchips, and hard drives.
- Software tells the hardware what to do and how to do it.
Application Programs
- An application program performs a specific function, e.g., PowerPoint.
Programming Language
- It serves as a human interface between the computer and programmer.
- A programming language allows a programmer to create an algorithm for the computer to follow.
- Algorithms are translated into machine code for the computer to understand.
