What are the differences among direct mapping associative mapping and set associative mapping?

User Avatar

Asked by Wiki User

In direct mapping, each block of main memory can only be mapped to one specific cache line. In associative mapping, each block of main memory can be loaded into any cache line. Set associative mapping is a combination of both, where each block of main memory can be mapped to a subset of cache lines rather than just one.

Differentiate pure and impure interpreter?

User Avatar

Asked by Wiki User

A pure interpreter only executes code and does not make changes to the underlying system, making it safer and more secure. An impure interpreter, on the other hand, may have the ability to modify the system or perform other actions beyond code execution, which can raise concerns about security and reliability.

What is upper bound in spss?

User Avatar

Asked by Wiki User

In SPSS, an upper bound typically refers to the maximum limit or cutoff point for a value or variable. It is used to define the highest permissible value in a range to prevent extreme values from skewing the data analysis results. Setting an upper bound can help to ensure data integrity and accuracy in statistical analysis.

Is Akhil Bhartiya Shiksha Sansthan New Delhi Valid University?

User Avatar

Asked by Wiki User

Akhil Bharti offers distance education (degree). However It is not recognized by UGC. You may as well do your degree from a recognized university. This will cause a problem for higher education ie if you want to do MBA after the degree, institutes will expect you to have a degree from a recognized university (recognized by UGC) . But if you want a degree just for the sake of a degree you can do it.

What are the advantages of using systems analysis and design techniques in approaching computerized information systems for business?

User Avatar

Asked by Wiki User

  1. System analysis enables the user to find and fix problems that are affecting the system. System analysis scans the system in different, individual sections to determine the problem and give the user a solution and possible requirements that are needed.
  1. Design Techniques show the user's software features in full detail which usually enable the user to see his/her software information in different formats, which include hierarchy diagrams and layout diagrams. These different ways of viewing software information are primarily used to enable programmers to create new software without having to spend additional time with the creation of software requirement designs.
