What is byte in assembly?
The BYTE directive tells the assembler to reserve a block of storage and remember its length in bytes. The length is determined by the number of bytes in the initializer, which could be numbers between 0-255 decimal, or characters in single quotes.

How many bytes is a letter?
Understanding bits and bytes We call 8 bits a byte. The very common ASCII system makes each letter of the alphabet, both capital and small (plus punctuation and some other symbols) correspond to a number from 0 to 255 (for example a=97, b= 98 and so on), so one letter can be expressed with one byte.
What are bytes?
In most computer systems, a byte is a unit of data that is eight binary digits long. A byte is the unit most computers use to represent a character such as a letter, number or typographic symbol. Each byte can hold a string of bits that need to be used in a larger unit for application purposes.
