In the life of the PC repair technician, the really fun stuff (such as replacing the motherboard, upgrading the processor, or tracking down a transient error in memory) is only a small part of the job. The real work involves more mundane tasks, such as installing a new printer, connecting an external modem, rigging a nifty new mouse or keyboard, or adding the pizzazz of a digital camera. In spite of my feeble attempts to make these tasks sound exciting, they’re not much more than connecting the device’s cable and connector to one of a PC’s ports. That’s the stuff that fills your hours. That’s why the A+ Core Hardware exam emphasizes knowing different types of ports in use, the types of connectors used with them, and the proper way to connect.
Time Shaver You should know these characteristics about ports and connectors for the test:
The types of devices that use each port type
The system resources used to configure serial and parallel ports
The standards that define each of the common port types
The connectors, meaning their sizes and shapes, and cabling used with each port type
You should know these port types for the test: IEEE 1394/FireWire, infrared (IR), parallel, serial, and USB.
