The purpose of this document is to provide a high-level overview of the core aspects of computer technology. This document is not meant to be comprehensive, but rather to provide a general understanding of the key components of modern computing.
The hardware of a computer system consists of the physical components that make up the machine. This includes the processor, memory, storage, input/output devices, and networking components.
- Processor: The processor is the brains of the computer, performing the instructions of a program. Modern processors are very fast, able to perform billions of operations per second.
- Memory: Memory is used to store data and programs while they are being used by the processor. There are two main types of memory: volatile and non-volatile. Volatile memory, such as RAM, is lost when power is removed from the system. Non-volatile memory, such as ROM, persists even when power is removed.
- Storage: Storage devices are used to store data and programs permanently. Common storage devices include hard drives, SSDs, and flash drives.
- Input/Output Devices: Input and output devices are used to interact with the computer. Common input devices include keyboards, mice, and touchscreens. Common output devices include monitors and printers.
- Networking Components: Networking components allow the computer to connect to other devices and the internet. Common networking components include modems, routers, and Ethernet cards.
Software is a set of instructions that tells the hardware what to do. Software can be divided into two main categories: operating systems and applications.
- Operating Systems: Operating systems are the software that manages the hardware and provides a platform for applications to run. Common operating systems include Windows, macOS, and Linux.
- Applications: Applications are programs that perform specific tasks. Common applications include web browsers, email clients, and word processors.
- Data is the information that is processed by the computer. Data can be divided into two main categories: structured and unstructured.
- Structured data is data that is organized into a predefined format. Common examples of structured data include databases and spreadsheets.
- Unstructured data is data that does not have a predefined format. Common examples of unstructured data include text documents, images, and videos.
A network is a group of connected devices that can communicate with each other. Networks can be divided into two main categories: local area networks (LANs) and wide area networks (WANs).
- Local Area Networks: Local area networks are small, private networks typically found in homes and businesses. The most common type of LAN is a Wi-Fi network.
- Wide Area Networks: Wide area networks are large, public networks that span a large geographic area. The most common type of WAN is the internet.
