## Numbering System and Digital Logic [Simplified]

There are different numbering systems used in digital electronic circuits and computers. However, the numbering system used in one type of circuit may be different to that of another type of circuit, for example, the memory of a computer would use hexadecimal numbers while the keyboard uses decimal numbers. The different number systems are Decimal… Read More »

## Binary Numbers Arithmetic Operators – Two’s Complement [Explained]

Because of its widespread use, we will concentrate on addition and subtraction for Two’s Complement representation. The nice feature with Two’s Complement is that addition and subtraction of Two’s complement numbers works without having to separate the sign bits (the sign of the operands and results is effectively built-into the addition/subtraction calculation). Remember: −2n−1 ≤ Two’s… Read More »

## Why Computers Use Binary Code Numbers? [Answered]

Everyone of us about the decimal numbers i.e. 1, 2, 3, 4, 5, etc. However, there are many other numeral systems that exist, like hexadecimal numbers for example:3F2Bor binary numbers for example:10101011.Some may think these numbers cryptic and meaningless. These hexadecimal or binary code numbers can easily be converted to the well-known decimal numbers. Then… Read More »

## Binary to decimal conversion

Most real world quantities are represented in Decimal Number System. Digital Systems on the other hand are based on the Binary Number System. Therefore, when converting from the Digital Domain to the real-world, Binary numbers have to be represented in terms of their Decimal equivalents. The method used to convert from Binary to Decimal is… Read More »
