Software Engineering

When we consider a modular solution to any problem, many levels of abstraction can be posed. At the highest level of abstraction, a solution is stated in broad terms using of the problem environment. At lower levels of abstraction, a mmore detailed description of the solution is provided.

The process of evaluating software at the end of the software development process to ensure compliance with software requirements. The technique for validation is testing, inspection and reviewing.

Computers DO use analogue methods to transfer information.

Modems, for example (short for "Modulator/DEModulator") use either frequency shift or phase shift to transmit information.

Your monitor, even if it is a digital monitor, is using light to transmit information to your eyes, which is an analogue medium.

Even your wireless connection uses frequencies (analogue) representing ones and zeros to your computer; where the frequencies are converted back to ones and zeros by the wireless card.

There are number of SDLC models in software engineering. Using life cycle model we can divide the work in different phases thus making it easy and convenient .

Analysts, designers, programmers and testers are important members. There may be others, such as people involved in training or people who are involved in providing hardware for the system. Users can also be involved, as they will be the people using the software, so their input will be important.

One of the up and coming approaches is using screen video recording tools to capture bugs. It's an existing idea/technology employed in a new setting which delivers some clear productivity benefits. With a screen video capture tool running in the background recording all your testing, the moment you hit a bug, you have a clear record of what you did to create the bug. This benefits the software tester and the software developer in several ways. For the software tester it means that they don't have to go back and try to recreate the bug as they already have the exact steps they took. It also means that the software testers doesn't have to spend a lot of time writing up a detailed bug reports. From the developers perspective it's far easier to watch a video that's a few minutes long than wade through a detailed written bug report. Certainly I envisage these capture tools being integrated into popular defect tracking tools over the next year or so.

Black-Box Testing is a technique of testing without having any knowledge of the interior workings of the application.The tester is oblivious to the system architecture and does not have access to the source code. Typically, while performing a black-box test, a tester will interact with the system's user interface by providing inputs and examining outputs without knowing how and where the inputs are worked upon.

White-box testing is the detailed investigation of internal logic and structure of the code. White-box testing is also called glass testing or open-box testing. In order to perform white-box testing on an application, a tester needs to know the internal workings of the code.

the other system is to to insert a throttle valve at the flow lime of the pump and pressure gauge helps us knowing the STATIC head pressure.

Most of the nokia mobile phones uses SYMBIAN OS . For example N-series and E-series. Nokia have their own operating system also which is also used in some nokia phones (cheaper models).but most of the nokia phones uses SYMBIAN OS.

Pro engineer software is a computer-aided drafting program usually used by mechanical engineers to design the mechanics of an object, like a building.

The basic use of pro engineer software is for design purposes, whether it's a building or a car. The software is supposed to allow you to take the product from concept all the way through production.

RJ11(Registered Jack-11) has 4 to 6 pins. Generally 4 ports are there in RJ11.

in SSB-SC only one side band of AM s/g is sent frm Transmitter instead of both sideband and carrier in that of DSB-FC(DSB-FC consist of upper side band ,lower side band both conveying same information i.e. mirror image of each other and original carrier i.e. after the process of modeulation carrier is also present in DSF-FC s/g). thus DSB-FC = USB+LSB+Cariier hence total power in DSB-FC= cariier pow+ usb pow+lsb pow SSB-SC = either USB or lsb toatal pow= pow in single side band 1.using SSB-Sc power is saved. 2.Bandwith is reduced 3. noise immunity is more.

For any data flow diagram first look at the existing processes. Student registration, class selection, professor/teacher class assignment, testing, grading and I am sure the list goes on. Once you have provided the beginning scope of the software by pruning the list of existing processes you can then develop a list of documents and communications that are used to transfer information and authority to others in the system. It is these documents and activities that are data flow items. The entities that are involved in sending or receiving these same communications are nodes in the system. Of course this is cursory and very general answer.

Software development life cycle models show the ways to navigate through the complex process of software building. A project's quality, timeframes, budget, and ability to meet the stakeholders' expectations largely depend on the chosen model.

to my knowledge, animals who can be used for clothing are: snakes, rabbits, bears, alligators, crocodiles, big cats, and camel.

Multi-range ammeter using universal shunt

a group of flip-flops sensitive to pulse duration is called latch whereas a group of flip-flops sensitive to pulse transition is called a register.

Good system engineering begins with a clear understanding of context - the world view - and then progressively narrows focus until technical details are understood. System engineering encompasses a collection of top-down and bottom-up methods to navigate the hierarchy.

System engineering process begins with a world of view which is refined to focus more fully on a specific domain of interest. Within a specific domain, the need for targeted system elements is analyzed. Finally, the analysis, design, and construction of targeted system element is initiated. Broad context is established at the top of the hierarchy and at the bottom, detailed technical activities are conducted. It is important for a system engineer narrows the focus of work as one moves downward in the hierarchy.

A Software Developer requires leadership skills

heterogeneity challenge: aka being able to use older software on newer operating systems .it is often necessary to integrate new software with older legacy systems written in diff programming languages .

delivery challenge: making it small to be albe to transfer fast to the clients

trust challenge: aka basically being able to trust the software being used by the users

Computers are used in biological research through internet and softwares. They are used as analysis of biological database, whole genome sequence analysis, prediction of protein structure and analysis of gene expression, protein expression , predict the transmembrane domain etc.

if you dont have alot of RAM (Memory) your computer will be slow
