One Sentence
One byte of RAM can hold up to one byte of data. This is equivalent to one 8-bit (ASCII) character, such as a keyboard letter, number, or symbol.
The size of a byte is typically hardware dependent, but the modern standard is eight bits. 8 bits can store 255 different values and this is enough to store one keyboard character. Therefore one byte can store one character of a text message.
A byte is the smallest unit of storage. Mostly anything you do can take up a byte.
8 bits in one byte
One byte of information is … one byte … regardless of where it is stored.
a character/byte as defined in the C programming language is one byte (8 bits). A string can be as short as one byte and can be as long as the physical memory limits can contain it.
In computers, a bit is a single digit of binary code. It is also one eighth (1/8) of a byte. This is because there are eight binary digits to make any letter of the alphabet, making one byte one single letter of text.
It isn't clear how you would measure a text message in minutes. Normally, text messages have a length in characters - each character is probably 1 or 2 bytes. A byte, of course, is one millionth of a MB.

Eight bits are in one byte
8 bits (Bit is short for binary digit.)
80 GB is equivalent to 80000000000 bytes; this is from the conversion: one gigabyte is equivalent to 1000000000 bytes. 80 GB is very big comparing its equivalent in the byte form.
