What is a megabyte?

Most computer users are very familiar with the megabyte. As you might have already guessed, a megabyte is the equivalent of 1,000,000 bytes (or 10^6 bytes). We should point out that there is more than meets the eye here. While the SI definition is one million bytes of information, many computing professionals will instead use the more precise number of 1,048,576 bytes (1,024^2). This arises from the binary multiples that occur (each byte contains eight bits of information within its string).

What is a terabyte?

The terabyte is the current heavyweight of all data storage. The terabyte represents 1,000^4 bytes. In other words, it is the equivalent of one TRILLION bytes of information. This can also be expressed in more technical terms as 1,024^4 (1,099,511,627,776) bytes. Thanks to advances in storage and processing power, the terabyte is now commonly seen in external hard drives and other systems which provide massive amounts of memory space. As the world of computing continues to advance, it will be interesting to see how far these massive figures will rise!
