A dedicated video graphics card (or video adapter) is an expansion card installed inside your system unit to translate binary data received from the CPU or GPU into the images you view on your monitor. It is another to the integrated graphics chip. Modern video cards embrace ports permitting you to attach to totally different video equipment; additionally, they contain their own RAM, known as video memory.
Video cards additionally also their own processors or GPUs for graphics processing are redirected to the processor on the video card, considerably rushing up the graphics process. Updating to a dedicated graphics card offloads work from the CPU and system RAM, so not only will graphics processing be faster, but the system’s overall performance will improve.
The video card additionally controls the number of colours your monitor will show. The number of bits the video card uses to represent every element on the monitor (referred to because the bit depth) determines the colour quality of the image displayed. The additional bits accessible, the higher the colour detail of the image.

In the bottom right you see the front panel audio connection which might be plugged into the microphone jack and headphone jack on the front of the case.
- Sound cards hooked up to the motherboard and enabled your pc to record and reproduce sounds.
- Most computers ship with a basic sound card, most frequently a 3D sound card. 3D sound is healthier than stereo sound at convincing the human ear that sound is omnidirectional, which means that you simply can’t tell what direction the sound is coming from. This tends to provide a fuller, richer sound than stereo sound.
- To originated surround sound on your pc, you wish 2 things: a collection of surround-sound speakers and a sound card that’s Dolby Digital compatible. There are several formats to settle on from like Dolby Digital EX, Dolby Digital Plus, and Dolby TrueHD
The ports on the sound card enable you to attach further audio devices like amplified speakers, headphones, microphones, etc.

A local area network needs that you simply install or attach network adapters to every pc or peripheral you wish to attach to the network. Most computers accompany local area network adapters preinstalled as network interface cards (NICs).
If your pc doesn’t have a NIC, your choices are:
- Buy one and install it, or
- Use a USB adapter, which you plug into any open USB port on the system unit.
