• 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.
