Refer books written by Mazidi on microcontrollers and start to work on basic keil software and if u are working on some advanced microcontrollers, go for proteaus.

* What is Bit? (Definition of Bit)

Ans 1 - Definition: A Bit is a digit in the binary number system. It can have two values, 0 or 1. In computer RAM and ROM memory, a bit is a small electrical switch which is either on (value 1) or off (value 0).
However bits don't exist individually but in groups of 8 and that is a byte. So one Kilobyte of RAM = 1024 bytes or 8192 bits.
Ans 2 -A bit is the basic unit of information in computing and digital communications. A bit can have only one of two values, and may therefore be physically implemented with a two-state device. The most common representation of these values are 0 and 1. The term bit is a contraction of binary digit.

Other information:-

1 bit = a 1 or 0 (b)

* What is Binary?

Ans 1 -

In mathematics and computer science, the binary numeral system, or base-2 numeral system, represents numeric values using two symbols: typically 0 and 1.

Ans 2-

Definition: Binary refers to base two arithmetic using the digits 0 and 1. This corresponds to the electric current in a wire- its either On (a value of 1) or Off ( a value of 0) and this is known as a bit, derived from Binary dIgiT.

What is Hexadecimal number system?

Ans 1-

Definition: The hexadecimal number system (also called base-16) is a number system that uses 16 unique symbols to represent a particular value. Those symbols are 0-9 and A-F.
The number system that we use in daily life is called the decimal, or base-10, system and uses the symbols 0-9 to represent a value.

Ans 2-

In mathematics and computer science, hexadecimal (also base 16, or hex) is a positional numeral system with a radix, or base, of 16. It uses sixteen distinct symbols, most often the symbols 0–9 to represent values zero to nine, and A, B, C, D, E, F (or alternatively a–f) to represent values ten to fifteen. For example, the hexadecimal number 2AF3 is equal, in decimal, to (2 × 163) + (10 × 162) + (15 × 161) + (3 × 160), or 10995.

*Decoders

Decoders are widely used for address decoding in computer design.



*Flip-Flops



Flip-Flops are frequently used to store data.

Unit of data size

· 1 Bit = Binary Digit
· 8 Bits = 1 Byte
· 1024 Bytes = 1 Kilobyte
· 1024 Kilobytes = 1 Megabyte
· 1024 Megabytes = 1 Gigabyte
· 1024 Gigabytes = 1 Terabyte
· 1024 Terabytes = 1 Petabyte
