7.Optical Drives
Though less common than they used to be, many machines still have an optical drive for reading CDs and DVDs. These can be used to listen to music or watch movies, place information onto a blank disc, or install software from a disc. Since most software nowadays is installed from the internet instead of using discs, these aren’t as important as they once were, especially on laptops.
8.Input and Output Devices
Depending on your particular computer, you can connect a variety of devices to send information into it or out of it. Common input devices include mice (touchpads on laptops), keyboards, and webcams, while output devices consist of monitors, printers, and speakers. Removable media such as flash drives and SD cards can also be used to transfer data between computers.
