Study Notes
Computer Architecture
- Computer architecture is a set of rules and methods that describe the functionality, management, and implementation of computers.
- It deals with the functional behavior of a computer system.
- It tells us how computer hardware and software are implemented and placed inside a computer system.
Computer
- A computer is a machine that executes certain commands set by the user.
- A computer is broken into two basic categories: Hardware and Software.
Hardware
- Hardware refers to everything you can take in your hands.
- Examples of hardware include: screen, mouse, keyboard, PC case, everything inside that case, printer, etc.
Hardware Categories
-
Input: Devices that are used to input commands or data into the computer system.
- Examples: Keyboard, Mouse, Touchscreen, Microphone.
-
Output: Devices that the computer uses to show the user processed data or outcomes.
- Examples: Watch/Screen, Printer, Speakers, Projector.
-
Processing: Devices that the computer system uses to carry out instructions and manipulate data.
- Examples: CPU (Central Processing Unit), GPU (Graphics Processing Unit), RAM (Random Access Memory), Motherboard.
-
Hybrids: Devices that combine characteristics of both input and output devices or blur the lines between them.
- Examples: Touchscreen Displays, 2-in-1 Laptops, Interactive Whiteboards, Smart Home Devices (e.g., Amazon Echo, Google Home).
Processing
- A processor (CPU) is the logic circuitry that responds to and processes the basic instructions that drive a computer.
- Storage is a process through which digital data is saved within a data storage device by means of computing technology.
Memory/Storage
-
Primary Storage: Internal Memory.
- ROM (Read Only Memory): Keeps data forever, even when the computer is not in use.
- RAM (Random Access Memory): A kind of volatile memory used to hold machine code and data that must be quickly accessed by the CPU.
-
Secondary Storage: External memory.
- Hard drives: An example of secondary storage.
Software
- Is divided into two categories: System Software and Application Software.
System Software
- Refers to a collection of programs that control and manage the hardware resources of a computer system.
- Makes it easier for the system's hardware and software components to communicate with one another and offers a platform for the execution of application software.
- Examples: Operating systems, device drivers, utility apps, and other software that is necessary for a computer to run.
Application Software
- Applications created with specific functions or tasks in mind for end users.
- Examples: Word, Paint, etc.
