Lesson 3 Summary Maintaining Hardware
Lesson 3
Decisions about what kind of computer to buy should be based on what you want a computer to do.
The kind of software you want to run should also help you decide what kind of computer to buy.
It is important to register new equipment to activate the warranty and technical support.
Input and output devices are connected to the computer through serial and parallel ports.
The Universal Serial Bus is a newer standard that is beginning to replace serial and parallel ports.
There are several types of ports: USB, SCSI, MIDI, parallel, and serial.
Cables connect peripherals to the computer.
Many hardware devices today are designed to be plug and play, so the operating system recognizes the new hardware and configures the system for it to work correctly.
A regular visual inspection of your computer system can help you find loose cables and other potential problems before they affect how the computer runs.
Keeping your computer system clean is another way to avoid serious problems.
Troubleshooting involves analyzing problems to correct faults in the system.
Power outages and power surges can both damage hardware and corrupt data, so it is important to protect your computer system from fluctuations in the power supply.
Protect your computer from theft, viruses, and hackers by taking basic security precautions.
To maintain a permanent copy of data, you must store it on some type of storage medium. These may include floppy diskettes, hard drives, CDs, magnetic tape cartridges, and WORM disks.
