What are the major disadvantage of file processing system?
File processing system is inconsistent and disintegrared.It is difficult to access and may be present on different platforms which would not allow to integrate data
GT Ststrudl is a structural engineering software system that is computer aided. The software is designed to assist engineers in the structural designs and analysis process.

What are the advantages of SONET over PDH?
•Plesiochronous Digital Hierarchy (PDH) is the original standard for telephone network, now abandoned in favor of SONET/SDH • Exploits Time Division Multiplexing
• Designed to support digital voice channels at 64kb/s
•No store and forward: imposes strict synchronization between TX and RX. A "plesio-synchronous" (almost synchronous) solution is adopted
• Different standards in US/Europe/Japan
SONET:
•Synchronous optical networking is a method for communicating digital information using lasers or light emitting diodes (LEDs) over optical fiber.
•SONET was introduced to handle large amount of telephone calls and interoperability between equipments of different vendors.
•Synchronous networking differs from PDH in that exact rates that are used to transport the data are highly synchronized across the entire network, made possible by atomic clocks.
What is the impact of reversing the polarity of a CT in a 3phase and 4wire metering arrengement?
The net measured power would appear to be negative, or reversed.
The Booch software engineering methodology [#!booch!#] provides an object-oriented development in the analysis and design phases. The analysis phase is split into steps. The first step is to establish the requirements from the customer perspective. This analysis step generates a high-level description of the system's function and structure. The second step is a domain analysis. The domain analysis is accomplished by defining object classes; their attributes, inheritance, and methods. State diagrams for the objects are then established. The analysis phase is completed with a validation step. The analysis phase iterates between the customer's requirements step, the domain analysis step, and the validation step until consistency is reached.
Once the analysis phase is completed, the Booch software engineering methodology develops the architecture in the design phase. The design phase is iterative. A logic design is mapped to a physical design where details of execution threads, processes, performance, location, data types, data structures, visibility, and distribution are established. A prototype is created and tested. The process iterates between the logical design, physical design, prototypes, and testing.
The Booch software engineering methodology is sequential in the sense that the analysis phase is completed and then the design phase is completed. The methodology is cyclical in the sense that each phase is composed of smaller cyclical steps. There is no explicit priority setting nor a non-monotonic control mechanism. The Booch methodology concentrates on the analysis and design phase and does not consider the implementation or the testing phase in much detail.
What are the modules in software engineering?
For the sake of clarity, I will assume you are talking about the software engineering process itself. However, one can very easily refer to specific modules in a programming library such as Microsoft's .NET. In this instance modules would be categorized into the similarity of their functions, for instance Math, I/O, Networking, GUI, etc...
However in a basic sense,
Modules are simply just a convenient way to break down the main problem and divided into many sub problems/solutions. This way the main problem can be broken down into solutions that a team can work on. A module could consist of a the printing functionality of program. This can be handed to one programmer. The GUI (Graphical User Interface) could be another module, handed to another programmer, and so forth.
Modular design is meant to improve efficiency and speed of development by allowing programmers to work on specific aspects of the program independently of each other.
Which thing should be learned by engineering students of computer science besides the course?
Evey engineering student must make sure to get aware of the currently evolving technologies (which wont be taught in the course). Learn about basic web development, GUI based application development. These will assist you when you are doing projects as part of the course.
Follow up with technology news, read about developments in open source communities, and always be updated on the latest computer hardware and software.
How does EDRM software is related with E-Discovery?
From information management through production and presentation, the Electronic Discovery Reference Model (EDRM) provides a standardized process for managing electronic discovery
What is risk analysis and risk exposure and what are the techniques you can use to mitigate risk?
Once the risks have been identified, you need to answer two main questions for each identified risk:
1. What are the odds that the risk will occur,
2. If it does occur, what will its impact be on the project objectives?
You get the answers by performing risk analysis.
There are two main forms of Risk Analysis:
1. Qualitative Risk Analysis &
2. Quantitative Risk Analysis
You Mitigate Risks by first analyzing the risks and then taking steps to ensure that the risks are prevented.handled during the course of your project execution
What are the prototyping methodology?
A prototyping methodology is a software development process which allows developers to create portions of the solution to demonstrate functionality and make needed refinements before developing the final solution.
What are applications of context-aware computing?
- Productivity applications similar to Zahdoo
- Digita Information Retrieval
- Cognitive Application
- Wearable Computing Applications
- Virtual or smart assistant applications such as Siri and Zee
Which SDLC paradigm will be selected in library information system?
The Spiral model seems as an ideal choice here. No other model seems a reasonable alternative to accept as a different answer.This model combines the features of the prototyping & the waterfall model.As library information system for a university is a large project,therefore spiral model is intended for large,complex,expensive & complicated projects.
What is white box testing in software engineering?
White box testing is when the tester has full access to and knowledge of the unit under test.
Black box testing is when he doesen't and is only allowed to enter inputs and verify outputs.
Each has advantages.
What was Intel's first multicore processor?
Intel's first multicore processor was the Xeon, followed the same year (2002) by the Pentium IV. The two cores were implemented in a hyperthreading configuration, allowing two simultaneous threads when both threads were in the same process address space.
Independent cores (in different address spaces) were supported starting with the Core-2 Duo. This configuration extended the hyperthreading model to include duplicating enough of the bus interface unit to allow two unrelated threads to run simultaneously.
