Computer Basics
Computers are electronic devices that can store, process, and retrieve data. Here are some basic concepts in computer science:
Hardware: The physical components of a computer, such as the CPU, RAM, hard drive, and peripherals like the keyboard, mouse, and monitor.
Software: The programs and data that run on a computer, including the operating system, applications, and files.
Operating system: The software that manages the computer’s resources and provides a user interface for interacting with the computer.
CPU: The central processing unit, or “brain” of the computer, which performs arithmetic, logic, and input/output operations.
RAM: Random Access Memory, a type of computer memory that allows data to be accessed quickly in any order, and is used to store running programs and data.
Hard drive: A device for storing data permanently, using spinning disks or solid-state memory.
Input devices: Devices used to enter data into the computer, such as a keyboard, mouse, or touchscreen.
Output devices: Devices used to display data from the computer, such as a monitor, printer, or speaker.
Networks: A group of computers and other devices that are connected to each other, either physically or wirelessly, allowing them to share resources and communicate. Programming: The process of creating software programs that can be executed on a computer, using languages such as Python, Java, or C++.
