In structure chart whole application is divided into modules (set of program instructions) and modules are designed according to some principles of design. These are:
Modularity and partitioning: Every system must comprises a hierarchy of modules. Lower level modules are usually smaller in size and scope compared to higher level modules. They serve to partition processes in separate functions.
Coupling: Modules must be loosely coupled. Which means that modules must have little dependence on other modules in a system.
Cohesion: Modules must be highly cohesive. It means that modules must carry out a single processing function.
Span of control: Modules must interact with and manage functions of a limited number of lower level modules. It means that number of called modules must be limited (in a calling module).
Size of Module: Number of instructions present in a module must be limited so that module size is normally small.
Shared use of Functions: Functions must not be duplicated in separate modules may be shared. It means that functions can be written in a single module and can be invoked by any other module when required.
Highly Encoded micro-instructions Encoded bits required in micro-instructions are small. It provided an aggregated view that is a higher view of CPU as just an encoded
Problem (a) What do you meant by a file system? (b) Mention the five categories of data for a basic file system reference model. What is the use of such a reference model
Q. Working of Fully Parallel Associative Processor? Fully Parallel Associative Processor: This processor accepts the bit parallel memory organisation. There are 2 kinds of this
Object Orientation and Analysis An Object is anything that exists within the problem domain that can be recognized by data and/or behaviour. An example of an object is a bike.
Consider the data with categorical predictor x 1 = { green or red } and numerical predictor x 2 and the class variable y shown in the following table. The weights for a round
Illustrate how 74147 series TTL can be used as a decimal-to-BCD encoder. Ans. Available IC in 74 series is 74147 that is a priority encoder. Such IC has active low inp
Q. Show Programming Based on Data Parallelism? In data parallel programming model the focal point is on data distribution. Every processor works with a part of data. We will co
tCAS is the number of clock cycles required to access a particular column of data in SDRAM. CAS latency is the column address strobe time, sometimes referred to as tCL.
Determine the term Queries-DBMS Queries most commonly allow information to be retrieved from tables. As the information is often spread across numerous tables, queries allow it
How does VB.NET/C# achieve polymorphism? VB.Net / C# provide polymorphism through the following mechanisms: 1. Inheritance - base class gives overridable methods which ar
