Study Notes

Computers

A computer is an electronic device designed to store, retrieve, process, and transmit digital data. It operates through hardware components such as the central processing unit (CPU), memory, input/output devices, storage media, and peripherals. These components interact through system software that manages various functions of the computer.

Software

Computer software refers to programs designed to run on computers. It includes operating systems, application software, utility software, and programming software. Operating systems manage computer resources and provide common services for applications. Application software enables people to do work using a computer. Utility software helps users optimize their desktop performance by managing files, installing and removing software, and backing up data. Programming software allows programmers to create new applications.

QBASIC Programming

QBASIC is a version of BASIC programming language that was included with Microsoft Windows from Windows 3.1 to Windows XP. BASIC stands for Beginner's All-purpose Symbolic Instruction Code. Through QBasic, users could develop games and small applications on personal computers without needing more advanced programming knowledge. However, several limitations made QBasic less popular among developers compared to other languages such as C++ and Java.

Hardware

Computer hardware refers to the physical parts of a computer, such as the CPU, memory, input/output devices, storage media, and peripherals. The CPU is the brain of the computer, performing most of the processing. Memory stores data temporarily while the CPU processes it. Input/output devices like keyboards and mice allow users to interact with the computer. Storage media like hard drives and solid-state drives store data permanently. Peripherals, such as printers and scanners, connect to the computer via USB and other ports.

Networking

Computer networking refers to the connections between computers that enable them to share data and communicate with each other. This can occur via wired connections, such as Ethernet, or wireless connections, such as Wi-Fi. Networking is crucial for many applications, including email, file sharing, and online gaming. It also allows businesses to connect to the internet and sell products or services online.

In conclusion, computers are essential tools for storing, processing, and transmitting digital data. They function through hardware components and software programs, enabling a wide range of applications and networking capabilities. QBASIC programming was a version of BASIC that allowed users to develop simple applications on personal computers, but its limitations led to the rise of other programming languages.
