Study Notes
Computer Hardware
- The physical components of a computer system are referred to as computer hardware.
- The Central Processing Unit (CPU) is the brain of the computer, carrying out instructions and performing calculations, and determines the computer's processing power and speed.
- Memory (RAM) is the computer's temporary storage space, allowing the CPU to quickly access and store data while programs are running, and more RAM enables smoother multitasking and faster performance.
- Storage devices hold data for the long term, with two primary types: Hard Disk Drives (HDD) and Solid State Drives (SSD).
- HDDs are traditional, mechanical drives with high storage capacity but relatively slower read/write speeds.
- SSDs are faster and more reliable drives that use flash memory, providing quicker data access but with a higher cost per gigabyte.
- Input and Output Devices allow users to interact with the computer, including keyboards, mice, monitors, and speakers.
Computer Software
- Software refers to the programs and applications that run on a computer system.
- The operating system (OS) is the core software that manages the computer's hardware and software resources.
- Application software performs specific tasks based on user needs, including web browsers, word processors, spreadsheets, and media players.
Software Installation and Management
- To install software, obtain the software installer, double-click the installer file, and follow the on-screen instructions.
- Customize the installation settings if needed, and click "Finish" or "Install" to complete the process.
- Regularly updating software ensures you have the latest features and security patches.
- Most software provides automatic update options, or updates can be checked manually within the software or its official website.
- To remove software from your computer, go to the Control Panel (Windows) or Applications folder (macOS), locate the software, select it, and click "Uninstall" or "Remove."
