One of the most important indicators of a computer's efficacy is its speed. A
computer's speed is determined by a few important aspects.
The speed of a central processing unit is measured in gigahertz, but a higher number does not always imply a quicker CPU. The size of its cache, measured in megabytes, and the number of processing cores are also important.
A CPU cache is a data storage and retrieval area for this microprocessor. More data can be stored in a larger cache. The CPU can perform more operations at once with several cores.
Random access memory is inserted on the motherboard in the form of 'sticks.' RAM has its own megahertz values, and more RAM means a quicker machine in general.
A hard drive is where all of your computer's files are stored for the long term. Its transfer rate is measured in megabytes per second. Like a CPU, a hard disc can have a cache.
Viruses and spyware can cause your computer to slow down. Antivirus software helps protect a computer from the slowdowns that come with malware outbreaks.
