which computer it is you're using. Clicking on the Apple menu in the upper

left corner,

choose "About This Mac." This window now gives us the core

information about the computer, beginning with

Mac OS X being Apple's Macintosh computer operating system.

Version 10.9 being Mavericks. Near the bottom,

"More Info" elaborates on the summary. This now tells us the name of the

hardware.

In this instance, a MacBook Pro, Early 2013 model.

Clicking Displays in upper left corner

tells us the resolution, in addition to the capabilities of the graphics card.

Storage lest us know the capacity,

and how much space you have available internally. It even breaks down into

categories

which media is consuming how much space, and how much space is remaining

on the drive. By connecting other external devices such as

flash drives or external hard drives, this

window can tell us about those as well. Memory

is not the same Storage. Memory

determines the fluidity of the operating system, especially when you're multitasking,

and how smooth everything will behave at once. Memory,

unlike storage, actually determines the performance of the computer.

They're not the same, although the term 'memory' is interchangeable

with 'RAM.' Continuing all the way to the right,

the Support tab informs us of all the resources available provided from Apple

about learning your computer, in addition to the

Service tab and support.
