Study Notes

A computer is an electronic device that can store, process, and communicate information.
The term "computer" was first used in the 17th century to describe a person who performed calculations.
The modern electronic computer was developed in the 20th century, with the first electronic computer, ENIAC, built in 1946.

Hardware: The physical components of a computer, including:
- Central Processing Unit (CPU): executes instructions and performs calculations
- Memory (RAM): temporary storage for data and applications
- Storage Drive: long-term storage for data and programs
- Input/Output Devices: keyboard, mouse, monitor, etc.
Software: The programs and operating systems that run on a computer, including:
- Operating System (OS): manages hardware and provides a interface for users
- Application Software: programs that perform specific tasks, such as word processing or web browsing

Desktop Computers: designed for use on a desk or table
Laptop Computers: portable and designed for use on a user's lap
Mobile Devices: smartphones and tablets that combine computer and phone functionality
Servers: powerful computers that manage and provide access to resources over a network
Supercomputers: high-performance computers used for scientific simulations and data analysis
