Study Notes
Video Card
- A video card, also called a graphics card, outputs images to a display.
- Some offer extra features like video capture, TV tuners, and multiple monitor support.
- Most include a GPU (graphics processing unit), a specialized processor for 3D graphics.
- A video BIOS controls the card's operation and interaction with computers/software.
- Integrated video cards use computer RAM for graphics.
- Dedicated video cards have their own Video RAM (VRAM), ranging from 128MB to 2GB.
- A RAMDAC converts digital signals from the processor to analog signals for the display.
- Outputs include HD-15 (monitor cable), DVI, S-Video, composite, and component video.
Sound Card
- A sound card facilitates audio input/output controlled by computer programs.
- Used in multimedia applications like music, video/audio editing, presentations, and entertainment.
- Many computers have built-in sound capabilities; others require expansion cards for audio.
Network Card
- A network card allows computers to communicate on a network.
- Enables wired and wireless connections between users.
- Ethernet is a common networking technology.
- Every Ethernet card has a unique 48-bit MAC address stored in ROM.
