Q. How codes represent data for scientific calculations?
How codes are in fact used to represent data for scientific calculations?
The computer is a discrete digital device and stores information in flip-flops that are two state devices means in binary form. Fundamental requirements of computational data representation in binary form are:
The solution for sign representation is easy since sign can be either negative or positive hence one bit can be used to signify sign. By default it must be left most bit (in most of the machines it's Most Significant Bit).
Therefore a number of n bits can be represented as n+l bit number where n+lth bit is sign bit and rest n bits signify its magnitude.
Figure: A (n + 1) bit number
n=(x*2)/(1=0) the value x=0 and is used to stop the algerithin.The calculation is repeated using values of x=0 is input. There is only a need to check for error positions. The va
Why a computer expect to receive responses when it broadcast an ARP request? Response will be acquired only from the machine for that request is being sent not for the other ma

Aggregation is the relationship among the whole and a part. We can add/subtract some properties in the part (slave) side. It won't affect the entire part. Best example is Car,

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,
