This week: Bits, Bytes, Kilo, Mega and Giga
In talking to clients about memory and hard drive space and suggesting that their PC can use up to 8 gigabytes or a hard drive of 500 gigabytes, I find them nodding in agreement but not in complete understanding of what I speak, so here is a short discourse on computer talk.
BIT – the very basic item, the building block of all of we know as computers. A bit is a switch, either on or off. In a large sense, the PC itself is a Bit, again either on or off. In the original computers, these switches were arrays of ferrous metal rings with wires running through them; if a ring had power, it was a “1;” if off, it was a “0.” This array was called the “Core;” we now call this core the CPU. The first core I saw was about eighteen inches square and had 64 KiloBYTES of work space in a room-sized computer. The current CPU has more than a GigaBYTE, in a one- half-inch square.
BYTE – A byte is 8 bits; it takes one byte to generate one letter or character. The letter A is 1000001 in binary; the amount of storage is based on how many bytes the media can hold. In the Gigabyte CPU chip, the 1’s and 0’s are turned on in transistors; on a hard drive, they are magnetic spots on the disk media, and the 1’s and 0’s are represented by which direction the north and south poles are oriented. Hard drives have gained storage space by being able to shrink the size of the magnets on the media.
A KILObyte is 1,000 bytes; a MEGAbyte is 1,000,000, and a GIGAbyte is 1,000,000,000.  BYTES are electronic, so it is hard to fathom their size, as the size of hard drives has not changed in 40 years, but the amount of data that can be saved on them has increased exponentially. The same applies to RAM memory, the part of the PC that holds data from the hard drive while waiting for the CPU to retrieve it for execution. The more memory a PC has for this temporary storage, the faster your PC is, as the CPU is not waiting for data from the very, slow hard drive to transmit its data. This is why GIGAbytes of RAM memory is important.
