Issue 20.11
This week we conclude the list of the names and basic descriptions of computer parts so you can talk intelligently when you need to speak with or hire a technician. Our attention currently is on the internal boards that attach to the motherboard to connect to your peripherals such as speakers, monitors, printers, scanners, cameras, and your wireless or wired network.
The following items can either be plugged into a slot on the motherboard or may be “integrated” or built into the motherboard. Integrated components are less expensive but are more difficult or even impossible to upgrade or replace in some cases.
Graphics Controller – Controls the quality, size and speed of images shown on the monitor. There are a wide range of capabilities and prices on this item, but top-of-the-line power is not needed for most computer functions other than extreme gaming or movie and graphic editing. Some people will spend over $1,000 for a graphics controller that will give them an “edge” in an online game.
Sound Controller – Versions include simple sound reproduction to powerful recording studio capabilities with surround and digital light-wire systems.
Ports – can include USB (Universal Serial Bus), Firewire, Parallel, Serial (for older printers, cashdrawers, etc.), Ethernet (for networking) PS2 (for older keyboards and mice) and Modem (for telephone line communication) ports. These are used to connect the computer to peripheral equipment such as printers, cameras, scanners, keyboards, mice, etc.
There are many other components that can be part of a computer system. Having a simple working knowledge of the above items will help you communicate better with tech support or your local technician. Don’t be afraid to ask clarifying questions. It’s better to know what is going on. If the computer professional you are dealing with is annoyed or upset with your questions, you may want to find one that is more customer-oriented and willing to help you know what they are doing to serve you.
Have fun, but remember, stay safe – and make sure you have a backup of anything important.
