COMPUTER FUNDAMENTALS

Detailed explanation-1: -In the electronics world, each binary digit is commonly referred to as a bit. A group of eight bits is called a byte and four bits is called a nibble.

Detailed explanation-2: -An 8 bit binary number can represent a maximum of decimal 255= binary 11111111.

Detailed explanation-3: -For convenience, binary digits (bits, for short) are usually grouped together in two groups of 4 bits. This is 8 bits, or a byte, and is written using the hexadecimal numeral system. This would be shown as 1011 0011 = B3.

Detailed explanation-4: -An 8-bit unsigned integer has a range of 0 to 255, while an 8-bit signed integer has a range of-128 to 127-both representing 256 distinct numbers. It is important to note that a computer memory location merely stores a binary pattern.
