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
Instruction Length: Variable-length instructions (Intel 80x86, VAX) need multi-step fetch and decode, but permit for a much more flexible and compressed instruction set.
Explain BOOTP (Boot Strap Protocol). TCP or IP designer observed that several of the configuration steps could be combined in a single step if a server was capable to supply mo
Types of Pipelines: Instructional pipeline It is used where different stages of an instruction fetch and execution take place in a pipeline. Arithmetic pipeline
Chaining: In this method, instead of hashing function value as location we use it as an index into an array of pointers. Every pointer access a chain that holds the element having

What are the 3 segments of the default route, that is there in an ASP.NET MVC application? Ans) Segment 1st - Controller Name Segment 2nd - Action Method Name Segment 3r
POSIX is the IEEE's Portable Operating System Interface for Computer Environments. The standard provides compliances criteria for operating system services and is designed to allow
What is a digital multiplexer? Ans: Multiplexer: Data selector or MUX is a logic circuit selects binary information from one of several input and directs this to a sing
Q. How can we use Metropolitan Area Network? A MAN, essentially a bigger versions of a LAN is designed to extend over an entire city. It may be single network like a cable tele
