BIOS (basic input output system) and CMOS (complementary metal-oxide-semiconductor) both are essential parts of every computer’s motherboard. Let us have a look at BIOS and CMOS for their different tasks.

What is Multiplexer ?
Multiplexer is a combinational circuit that has 2n input lines and one of these inputs goes to single output lines. To select one from given 2n inputs, we have n selection lines. A multiplexer with 2n input lines...

What is Encoder?
An Encoder is a device that is used to change a signal (such as bitstream) or data into a code. The code may serve any of a number of purposes such as compressing information for transmission or storage, encrypting...

Subtraction can be done using various methods like direct subtraction of the corresponding bits or using complement’s methods as has already been discussed. If we use complement’s methods, subtraction is done using addition...

Full Adder is used to add three bits, i.e., when we also have a carry from the lower significant bit addition. Now, there will be three number of inputs and two outputs. Input variables are A, B which are the two bits that are to be added...

For designing a half adder, we will follow steps described follows –
As we know that half adder is used to add two bits, from the statement of the problem it is clear that we have to add two bits in binary.As two bits have to...

Adding two numbers is one of the basic tasks performed by a computer. Addition operation of two binary digits can be represented as follows –
For all values of A and B except 11, the result is a single digit value but for...

To Design a combinational circuit, we have to follow following steps—
The Problem should be clearly stated.Determine what are the input and output variables.Assign letter symbols to both input and output variables.Derive a truth...

Logical Circuits for digital systems can be two types – Combinational Circuits and Sequential circuits. Main difference between the two is that in combinational circuits, the output of the circuit at any time is determined by the...
