2. The Binary Code represents text or computer processor instructions using the binary number systems two binary digits, 0 and 1. A binary code assigns a bit string to each symbol or instruction. For example, a binary string of eight binary digits (bits) can represent any of 256 possible values and can therefore correspond to a variety of different symbols, letters or instructions.

MOOD OF THE DAY

It's Monday. I've had a busy weekend and that make me so tired.

The first three hours were hard because the teachers wanted to to advance fast in their subjects. The last three classes have been easier.

When I get home I have to eat fast to go to the dentist. I hope the dentist say me good news.

When I return home I do English and language homework.
