Software Engineering

Software engineering is the process of applying well-developed techniques and practices in order to create new software products. Questions about everything from design patterns to requirements and specification belong here.

Where is 094 mm in a ruler?

94 mm on a ruler is between 90 mm and 95 mm. On a typical ruler containing both mm and inches scales, where the scales are reversed with respect to each other, 94 mm is opposite 8 5/16 inches.

Which is good to make career on hardware networking or software development?

They are all good careers. You have to decide what you are interested in and what you are good at. Some may suit some people better than others. So different people will go into these different roles. There are needs for them, so whichever they go into, there will be jobs in them.

How do you fill self appraisal form for a software tester?

Software Tester have you set for yourself during the next year?

How can you do engineering in computers by taking commerce?

If you are to enter the commerce stream, the closest you can come to being a computer professional (by way of degree) is by selecting commerce subjects such as Commerce, Accounts, Mathematics and Statistics in your junior college years.

That combination of commerce subjects allows you to apply for a Bachelor of Science in Computer Science.

What is a specialized process model in software engineering?

Special process model take in many of the characteristics of one or more of the conventional models presented in the preceding section .however ,specialized models tend to be applied when a narrowly defined software engineering approach is chosen.

Why is it that many software developers dont pay enough attention to requirement engineering are there ever circumstances where you can skip it?

Because they are lazy. With the possible exception of very trivial projects, every project needs requirements engineering so that you can understand the requirements. Failure to perform the requirements engineering often leads to rework and lost effort. In point of fact, even the trivial projects get requirements engineering - its just that the experienced developer has already done that before and can apply that knowledge to the new task at hand.

What are the arguments for and against considering system engineering as a profession and its own right such as electric engineering or software engineering?

²Communication difficulties

§Different disciplines use the same terminology to mean different things. This can lead to misunderstandings about what will be implemented.

²Differing assumptions

§Each discipline makes assumptions about what can and can't be done by other disciplines.

²Professional boundaries

§Each discipline tries to protect their professional boundaries and expertise and this affects their judgments on the system.

What is write assembly cache?

the goal of write assembly cache is to assemble writes so that they can be transmitted to memory in an orderly way.

Why software requirement specification is also called black box specification?

It should only specify what the system should do and refrain from stating how to do these. This means that the SRS document should specify the external behavior of the system and not discuss the implementation issues. The SRS document should view the system to be developed as black box, and should specify the externally visible behavior of the system. For this reason, the SRS document is also called the black-box specification of a system.

What is procedural design?

Procedural design is when the programmer specifies what must be done and in what sequence. It is based on the concept of the modularity and scope of program code.

Can air cards be traced?

Yes. They are, for all practical purposes, a cell phone. If you had one stolen, report it to the police and the carrier, giving them the ESN and phone number.

Why digital modulation is not enough for radio transmission and what are the general goals for digital modulation?

Worldwide regulation always uses FDM for separating different systems (TV, WLAN, radio, satellite …). Thus, all radio systems must modulate the digital signal onto a carrier frequency using analogue modulation. The most prominent system is the traditional radio: all music and voice use frequencies between, e.g., 10 Hz and 22 kHz. However, many different radio stations want to transmit at the same time.

Therefore, all the original signals (which use the same frequency range) must be modulated onto different carrier frequencies. Other motivations for digital modulation are antenna and medium characteristics. Important characteristics for digital modulation are spectral efficiency, power efficiency and robustness. Typical schemes are ASK, PSK, FSK.

What are the advantages of concurrent engineering?

Manufacturing Personnel are able to identify production capabilities and

capacities .They have thus the opportunity to inform the design group about the

suitability of certain materials on the flipsides the designer would know the

suitability of certain designs in aiding in cost reduction and quality improvement in

production/assembly process.

Early opportunities for design or procurement of critical tooling, some of which

might have long lead times.

early consideration of the Technical Feasibility of a particular design or a portion

of a design. Again this can avoid serious problems during production.

Which technology is remarkable in electronics field?

A What is remarkable is the search to implement solar components into cloth since our military uses an awfully amount of battery to run its communication equipment. That would be remarkable

How can you increase or double electric power output electronically?

A: Well that is not possible. Someone can change the voltage up or down with no problem but never can it increase power by adding any kind of circuitry for the simple fact of % efficiency loss. If it could be possible then we have infinite power source available.

When rad model of software development is used?

rad model is used when there is a time constraint............ this model is suitable for big projects where the customer requirements are clear

What is requirement validation?

Requirements validation is a critical step in the development process, usually after requirements engineering or requirements analysis. Also at delivery (client acceptance test).

What is incremental positioning in cnc machining?

A machine can measure either from the zero point, or from the last position that was. For example, when you say "X10", you mean 10mm from the zero point of the axis X, or you may mean 10mm further than the last position the machine was on the X axis. The way of measuring is decided from the G codes G90 and G91. Running the G90 command, the machine will start to measure using absolute coordinates (measuring from the zero point of the axis) and running the G91 command will set the machine into "incremental measuring".

For making matters more clear, see the following two examples. They generate both exactly the same thing, a rectangle as shown in file p7.jpg. The first code example uses absolute measurements and the second uses incremental measurements. At this point it should be said that almost all machines measures by default using G90 (absolute coordinates). For the following example, we suppose that somehow, the machines start from point 10,10 and not 0,0

What is mean by incremental forging?

In this forging method, very big forgings are made by working different areas of the forging in to shape, one at a time.

What is sentiment analysis?

The computational process of automatically determining what feelings a writer is expressing in the text is known as sentiment analysis. Sentiment Analysis is a method of gathering opinions with various scores, such as positive, negative, or neutral. The mood is sometimes expressed as a binary distinction (good vs. negative), but it can also be more nuanced, such as describing the exact emotion expressed by an author (like fear, joy or anger).

Why is silver used for making contact points in electric switches?

A: Because it is a very good conductor has many electrons 27 if I can remember correctly. There is a draw back to using silver that is because has the tendency to oxidize with oxygen as tarnish which occasionally must be eliminated to provide a good connection
