Q. Explain Keyboard Input and Video output ?
A Keystroke read from keyboard is termed as a console input and a character displayed on the video screen is known as a console output. In assembly language reading and displaying character is most tiresome to program. Though these tasks were greatly simplified by convenient architecture of 8086/8088. Thatarchitecture offers for a pack of software interrupt vectors starting at address 0000:0000.
The benefits of this type of call is that it appears static to a programmer however flexible to a system design engineer. For illustration INT 00H is a special system level vector which points to the 'recovery from division by zero' subroutine. If new designer come and want to move interrupt location in memory it adjusts entry in the IVT vector of interrupt 00H to a new location. So from the system programmer point of view it's relatively easy to change vectors under program control.
You should now have a reasonably clear understanding of what is meant by interaction design. However, there are several other terms which are often used to refer to particular aspe

This boils down to the concept of Binary digits. Take an array size of 64 for example. We begin from 0 and end at 63. We need 6 bits.But, if we were to begin from 1 and end at 64,
The maximum number of dimensions an array can have in C is C permits arrays of three or more dimensions. The exact limit is examined by the compiler.
Replacement and substitution: However, equivalences allow us to change one sentence with another without affecting the meaning, it means we know already that replacing one sid
