DOWNLOAD Your PC, Inside and Out Part 2 BY Lachlan Roy PDF
The CPU (Central Processing Unit) or processor is the brain of the computer – it’s where
all the calculations are carried out. Short of gaming, pretty much all the work a
computer does is carried out by the CPU; while RAM and hard drives are important,
they simply act as storage while data manipulation is carried out by the processor.
Clock Speed
One of the most common things you’ll see when looking at CPU specifications is the
processor’s clock speed, measured in gigahertz (GHz), with 1GHz being equal to 1
billion hertz or cycles per second. This means that a 1GHz processor is able to carry out 1
billion calculations every second. As a general rule of thumb a processor with a higher
clock speed is more powerful than one with a lower clock speed.
