For over two decades, people have used the term &#8220;CPU&#8221; to describe the big metal box sitting on the floor or desk. But calling that box a CPU is like pointing at your entire car and calling it the &#8220;spark plug.&#8221;<\/span><\/p>\n<p><span style=\"font-size: 14pt; font-family: helvetica, arial, sans-serif;\">Here&#8217;s what those terms actually mean:<\/span><\/p>\n<p><span style=\"font-size: 14pt; font-family: helvetica, arial, sans-serif;\">The Case (or Tower) \u2014 This is the large plastic or metal box. It houses the power supply, hard drive, fans, and motherboard. Its only job is to keep all the computer&#8217;s internal organs safely contained in one place.<\/span><\/p>\n<p><span style=\"font-size: 14pt; font-family: helvetica, arial, sans-serif;\">The CPU (Central Processing Unit) \u2014 This is the actual &#8220;brain&#8221; of the computer, and it&#8217;s nowhere near the size of that box. It&#8217;s a tiny silicon chip, roughly the size of a large postage stamp, tucked deep inside the case under a hefty cooling fan. The CPU handles all the calculating, processing, and thinking that makes your programs run.<\/span><\/p>\n<p><span style=\"font-size: 14pt; font-family: helvetica, arial, sans-serif;\">So next time you vacuum around your desk, remember: you&#8217;re cleaning around the computer *tower*, not the CPU.<\/span><\/p>\n<p><span style=\"font-size: 14pt; font-family: helvetica, arial, sans-serif;\">Speaking of things inside that tower that aren&#8217;t quite what they seem \u2014 your hard drive has a similar identity crisis.<\/span><\/p>\n<p><span style=\"font-size: 14pt; font-family: helvetica, arial, sans-serif;\">Buy a &#8220;500 GB&#8221; hard drive, and Windows will tell you it actually holds something closer to 465 GB. Did 35 GB just vanish? Not exactly \u2014 it comes down to two different definitions of &#8220;giga.&#8221;<\/span><\/p>\n<p><span style=\"font-size: 14pt; font-family: helvetica, arial, sans-serif;\">Hard drive manufacturers calculate storage using the decimal system, where 1 GB = 1,000,000,000 (one billion) bytes \u2014 clean, round numbers that make for great marketing. But your operating system counts in binary, the language computers actually speak, where 1 GB = 1,073,741,824 bytes (2^30). That&#8217;s roughly 7.4% more bytes required for each &#8220;GB&#8221; your OS reports.<\/span><\/p>\n<p><span style=\"font-size: 14pt; font-family: helvetica, arial, sans-serif;\">Do the math across 500 billion bytes, and that 7.4% gap adds up to around 35 GB of &#8220;missing&#8221; space \u2014 even though every byte the manufacturer promised is physically there.<\/span><\/p>\n<p><span style=\"font-size: 14pt; font-family: helvetica, arial, sans-serif;\">So the next time your shiny new drive shows up short, don&#8217;t blame your computer, and don&#8217;t blame the manufacturer for hiding your files. It&#8217;s just two different counting systems disagreeing about what &#8220;giga&#8221; means \u2014 and your operating system is doing the stricter math.<\/span><\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Your Computer Case is Not a CPU, and Your 500 GB Hard Drive Is Not 500 GB If you&#8217;ve ever crawled under your desk to plug in a cable and thought, &#8220;Let me just plug this into the back of the CPU,&#8221; you&#8217;re far from alone.
