How many hertz in a Giga whammy? Storage Sizes:The smallest increment of storage is a single bit, or Binary Digit. A
bunch of mathematicians got all coffeed up and decided it would be fun
to make a way to represent any number using only two digits, Zero and
One. You've probably heard that computers operate off of zeroes and ones,
and a bit is single zero or one. Computer CPU's (which stands for Central
Processing Unit) are essentially big transistors that have many many thousands
(millions?) of circuits on them. These circuits can be open or closed,
and depending on their state register as a zero or a one. That does me essentially zero good. The next unit is the Byte, which
is made up of 8 bits. By combining 8 instances of Zero or One, you can
make up to 256 combinations. The letters and numeric characters we use
in written communications can be represented by the American Standard
for Computre Information Interchange (ASCII). Alphanumeric characters!?
You're soaking in it!. Pretty exciting, huh? Next we have our friend the Kilobyte. Kilo is the
metric way of saying "thousand", so logically, a kilobyte is
roughly a thousand bytes. It's really 1024 bytes (2 to the ninth power,
2x2x2x2... 9 times. Whaddya want, there's only two digits.) How many kilobytes in a MegaByte? Incredibly, there are 1024 kilobytes
in a megabyte. A MegaByte is usually considered a million bytes, it's
really 1024 sqared, so 1048576 bytes in a Meg. No one seems to abbreviate
MegaByte the same way. Sometimes it's MB, or mb, or megs, or Mb. Hard
drives and ram are sold by the Meg. Time was when a Meg was a lot of storage. It's not now. A floppy holds
about 1.44mb, and most everyone has run out of space on a floppy before.
On the other hand, this little essay is only ...3654 characters long now,
including all the formatting and crap. So, a text only document a million
characters long is pretty damn big. I dare you to type a million characters.
I double mega dare you... Wow, that's sick. I don't even care to figure out how many bits that
is! Me neither. (I think there is another one, but I don't care to know for sure.)
Access Speed:RAM Access speed is measured in time. Typcally nanoseconds Right now if I open up my computer and get my RAM (Random Access Memory)
out, it's 8 NanoSecond pc 133 SDRAM ram. That means it's takes the RAM 8 billionths of a second to figure out if a circuit is open or closed, representing Zero or One. Processor Speed:Chip speed is based on hertz. Mega Herts usually abbreviated as Mhz. Hertz is defined as: hertz (hûrts) MegaHertz is one million cycles per second. By opening up the same compter, and looking at the processor (or CPU), I see that it's a 1200mhz chip. That means it does it's thing 1.2 billion times every second, whether it wants to or not. That's a hectic schedule.
