Study Notes
Peripherals for Computers
- Speakers and headphones are output devices that allow users to hear sound and music from the computer.
- Microphones function as input devices, recording sound and enabling communication over the internet.
- Web cameras capture videos and images and support video conferencing in real time.
- Game controllers and joysticks enhance the gaming experience but a mouse and keyboard can also control games.
Computer Components
- The motherboard is the main circuit board of a computer, housing the CPU, memory, and connectors for drives and ports.
- The CPU (central processing unit) processes instructions, measured in megahertz (MHz) or gigahertz (GHz) for performance.
- RAM (random access memory) acts as short-term memory, disappearing when the computer is turned off.
- Expansion cards can be added to enhance functionality, with common types being PCI (peripheral component interconnect) cards.
- Video cards are responsible for rendering visuals, with GPUs typically integrated into the motherboard.
Operating System
- The operating system (OS) is essential software that manages a computer's hardware and software resources, facilitating user interaction.
- It enables laptops and desktops to run applications and manage memory effectively, without a functional OS, a computer cannot operate.
Storage
- The hard drive provides long-term storage for software, documents, and files, retaining data even when the power is off.
- When documents are saved, they are written to the hard drive from RAM, ensuring data is not lost.
Power Supply
- The power supply unit converts power from the outlet to the type required by the computer, distributing it through internal cables.
Monitors and Input Devices
- Monitors display images and text, utilizing various technologies like LCD and LED, while older monitors use CRT technology.
- The mouse connects to the computer via USB or other ports, with optical and mechanical types available.
- Alternatives such as trackballs and touchpads offer different methods for controlling the pointer.
Interfaces and Ports
- The monitor port connects display devices, supporting formats like HDMI, DVI, and VGA.
- USB ports allow for connecting various devices, including mice, keyboards, and printers.
- Ethernet ports enable networking and internet connections, while audio ports support speaker and microphone connections.
Print and Scan Technologies
- Printers produce hard copies of documents and images, with types including inkjet, laser, and all-in-one options.
- Scanners create digital copies of physical images or documents, often as part of integrated printer solutions.
Safety and Maintenance
- Always ensure the computer is unplugged before opening the case for maintenance, and discharge static electricity by touching metal parts.
