A personal computer (PC) is a computing device made up of many
distinct electronic components that all function together in order
to accomplish some useful task (such as adding up the numbers in
a spreadsheet or helping you write a letter). By this definition, note that we're describing a
computer as having many distinct parts that work together. Most computers today are modular.
That is, they have components that can be removed and replaced with a component of similar
function in order to improve performance. Each component has a very specific function. In this

and how they work together inside the PC.
