Explanation:
In your small business, you may not have enough resources to have a full-time technical support employee. That might make you the default tech support, but don’t worry -- getting to know the inside of a computer isn’t that complicated. Computers are like any machine: a series of moving parts connected together to perform a task. The parts that connect the central processing unit (CPU) to the rest of the hardware are called the motherboard, power cables, and information cables.
The Motherboard
Your computer’s brain is the CPU: that’s where all of the programming and computing happens. But its nervous system is the motherboard, which uses circuits to connect the CPU to the other pieces of hardware, including the memory, the hard drive, the CD/DVD drive, and all of your peripherals. The motherboard is a complex piece of technology, with thousands of circuits to manage the transfer of information and electricity between the other component parts. Most motherboards are green, flat, and take up the entire base of a computer.
Power Cables
Both laptops and desktop computers have power cables on the inside as well as the outside. In day-to-day use, you’ll only even encounter the external power cable, which runs into a part of the computer called a power supply. The power supply gives power to the motherboard, which in turn powers the CPU. Power connectors also run from the motherboard to the hard drive and optical drives. On a laptop computer, an additional power cable connects to the display.
Information Cables
A computer is nothing if it can’t transfer information between the CPU and the rest of the hardware. Again, the motherboard plays an essential role here, but the actual transfer of data occurs in information cables called IDE cables. These connect the drives -- the hard drive and CD/DVD drive -- to the motherboard, which communicates with the CPU along a built-in information conduit called a bus.
Working Inside of A Computer
If your computer or any computer at your office has stopped functioning correctly, and if you’ve identified the problem as a hardware issue, you may need to work inside the computer to make sure everything is connected to the motherboard properly. Unplug the power cord from the back of the computer and press and hold the power button for a few seconds to let any captive electricity out of the circuits. Then open the computer’s case and look for the power cables and grey information cables. Lift each one from the motherboard and then place it back where you found it, pressing firmly to make sure it’s connected properly. In the case of a laptop computer, consider returning the computer to the shop from which you bought it -- working inside a laptop requires a lot of manual dexterity and very small screwdrivers.
