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.

Determine the synchronization of bits The synchronization provided by use of start and stop bits, an extra bit known as a parity bit may optionally be transmitted along with th
advantages and disadvantages of northwest corner method and least cost method
If the product of two integers a and b is even after that prove that either a is even or b is even. Answer: It is illustrated that product of a and b is even so let a * b = 2n.

a) Briefly describe the relationship between distributed computing, mobile computing and pervasive computing. b) Suppose the following scenario, which demonstrate the possibili
Explained RAID? Ans: High performance devices tend to be costly. So we can gain very high performance at a reasonable cost using a number of low-cost devices operating in paral
How to fix an ASIC-based design from easiest to most extreme? There are different ways to fix an ASIC-based design as given below: Initially, assume some reviews fundamentally.
Define Alphabet and String? A finite set of symbols is termed as alphabet. An alphabet is frequently signified by sigma, yet can be specified any name. B = {0, 1} here B is
Q Why we use addressing schemes? An operation code of an instruction tells the operation to be performed. This operation is executed on some data stored in memory or register.
