A number system is a set of digits used to represent he values derived from a common base or radix.

A nibble is half a byte, which is usually a grouping A of 4 bits. Word is the number of bits a processor car bundle (read/write) at a time.

The most basic unit of information in a digital computer is called a bit. A bit is a binary digit which can be 0, or 1.

Knowledge is identified from the information. Example: 10 % of Men around the worlds likes football

The given messages are represented in computer as Information \(\rightarrow \) Data \(\rightarrow \)Knowledge.

Associative
A + (B + C) = ( A + B) + C
A. (B. C) = (A . B) .C

The NAND is the combination of NOT and AND.The NAND is generated by inverting the output of an AND operator. The algebraic expression of the NAND function is : Y = A . B

1. BCD - Binary Coded Decimal.
2. EBCDIC - Extended Binary Coded Decimal Interchange Code.
3. ASCII - American Standard Code for Information Interchange,

(28)₁₀ is a positive number. 1's complement represent signed numbers (Negative numbers) only. So, (28)₁₀ cannot find 1's complement.

∴ 46₁₀ - 101110₂

Step 1: Convert given Decimal number into Binary
Step 2: Check if the binary number contains 8 bits. if less add 0 at the left most bit, to make it as 8 bits.
Step 3: Invert all bits (i.e. Change 1 as 0 and 0 as 1).

The term data comes from the word datum, which means a raw fact. The data is a fact about people. places or some objects
