5.Hard Disk Drive / Solid State Drive
Since RAM is temporary, your computer needs a place to store data permanently. That’s where the hard drive comes in. The traditional hard drive consists of several spinning platters with an arm that physically writes data to the disk. However, these drives are slow and are starting to be replaced by the faster solid-state drives.
Solid-state drives consist of flash memory, like your smartphone or flash drive. They are much faster than traditional hard disk drives, though cost more for the increased efficiency. Both types of drives come in various sizes to suit different needs.
6.Video Card
A video card is a dedicated unit for handling the output of images to a display. Video cards have their own dedicated RAM for performing these functions. A high-end video card is required to process extremely intense visual functions, such as computer drafting by engineers. Like many components, many types of video cards are available with varying power and prices.
