Study Notes
Computer Systems
- A peripheral device is a hardware component that provides input or output operations for a computer, such as a keyboard, mouse, or printer.
Examples of Peripheral Devices
- A scanner is a peripheral device that captures images or documents and converts them into digital data.
Types of Computer Systems
- The three main types of computer systems are: desktop, laptop, and mobile devices.
Operating System
- The purpose of an operating system is to manage and allocate computer resources, such as memory, processing power, and storage, to execute user applications.
Data Archiving
- Using a flash drive for daily data archiving is inappropriate because it has limited storage capacity and is prone to data loss or corruption.
Types of Computer Systems
- A desktop computer system is designed for stationary use and provides high processing power and storage capacity.
Hardware Components
- The five hardware components of a computer system are: central processing unit (CPU), memory (RAM), secondary memory (hard drive, solid-state drive, etc.), input/output devices (keyboard, mouse, monitor, etc.), and power supply unit (PSU).
Central Processing Unit (CPU)
- The purpose of the central processing unit (CPU) is to execute instructions and perform calculations, making it the "brain" of the computer.
Secondary Memory
- The purpose of secondary memory is to store data permanently, and it includes devices such as hard drives, solid-state drives, and flash drives.
Motherboard
- The motherboard is the main circuit board in a computer system that connects and supports all hardware components, allowing them to communicate and exchange data.
Random Access Memory (RAM)
- The role of Random Access Memory (RAM) is to provide temporary storage for data and applications, allowing the CPU to access and process information quickly.
Power Supply Unit (PSU)
- The purpose of a Power Supply Unit (PSU) is to provide a stable and regulated power supply to all hardware components in a computer system, ensuring reliable operation.
