In the 1980's I worked for Tandy Computer Centers consulting, selling and installing computers for small businesses and school systems. The most storage you had on a hard disk drive then was 10 megabytes and I was impressed since I was storing my data on a 186 kilobyte floppy disk. Today a 500 gigabyte hard drive is readly available even on the lower end computers Mid priced PC's can have 1 terabyte of disk storage space.
All of these byte words are really confusing to many computer users. The following displays the correlation of all these terms:
bit – the smallest piece of information used by the computer.
byte – a piece of computer information made up of eight bits.
1024 bytes = 1 kilobyte
1024 kilobytes = 1 megabyte
1024 megabytes = 1 gigabyte
1025 gigabytes = 1 terabyte
1 kilobyte = 1thousand
1 megabyte = 1 million
1 gigabyte = 1 billion
1 terabyte = 1 trillion
If you have a 500 gig hard drive it means your drive can store 500 billion characters. A 1 terabyte hard drive will store1 trillion characters which can translate into:
- 472 hours of broadcast quality video.
- 150 hours of hi-definition recording.
- Enough words that it would take every adult in America speaking at the same time five minutes to say them.
Do I need that much storage? Not really!
