Software Engineering

Validation is done at the end of the development process and takes place after verification process is completed. According to CMM we can also define it as the process of evaluating software during or at the end of the development process to determine whether it satisfies specified requirements.

One software I know is Auto-cad, which is needed for electrical Drawing.

• Highly visual and dynamic GUI. Any number of windows can be shown at once, all of which are automatically updated (and the file re-run) whenever data changes
• Junction Diagram - shows the junction in graphical format and includes queue animation, signal states, phases, stages, and results such as delay for each stream. The junction diagram allows access to all data for traffic streams and phases etc, and enables a new junction to be built graphically
• Phase timings diagram - shows phase and stage timings graphically, along with phase delays and intergreens
• Graph Generator - Allows any result (effective green time, delay, etc) to be plotted against any input parameter (cycle time, sat flow, etc). This serves as a very flexible sensitivity analysis tool
• Report Generator - reports are generated in HTML, in a format that can easily be pasted into a word processor or spreadsheet. The main diagrams are inserted in vector format, meaning that print-outs are very high quality
• Undo/redo allowing stepping back through up to 100 changes
• Quick edit mode - allows main data to be edited in a spreadsheet format
• All data can be accessed via a 'tree view' system and is therefore accessible from anywhere in the program
• Export to TRANSYT
• Importing from other well-known products including OSCADY Classic

Yes they are probably the same thing.After doing bscs, a person is called computer scientist but after doing SE, a person will be called an engineer. as far as subjects are concerned, they both are same :) hope that your satisfied.

Engineering seeks to apply the concepts of science in concrete situations. While scientists are concerned with discovering the abstract laws that govern nature, engineers use preexisting discoveries to design and improve structures or technology that benefit society. Therefore science and engineering perform complementary functions to a degree.

Flexibility: The ease with which a system or component can be modified for use in applications or environments other than those for which it was specifically designed We find this surprising because hardly any artefact is ‘flexible’ in absolute terms. The RAM capacity of a desktop computer, for example, can be expanded only if the hardware and the operating system were specifically designed to accommodate for such changes.

Rapid technological developments pervade every aspect of daily life, having a direct effect on the software we use. Every element of the software’s operational environment is in a state of constant flux: Frequent changes in the hardware, operating system, cooperating software, and client’s expectations are motivated by performance improvements, bug-fixes, security breaches, and attempts to assemble synergistically ever more sophisticated software systems. Classic and contemporary literature in software design recognize the central role of flexibility in software design and implementation. Structured design, modular design, object-oriented design, software architecture, design patterns, and component-based software engineering, among others, seek to maximize flexibility.

Process models can be used to help understand real processes and to identify which aspects of these processes could be supported by CASE tools.

Database,

*Each phase of an iteration is rigid and do not overlap each other.

* Problems may arise pertaining to system architecture because not all requirements are gathered up front for the entire software life cycle.

Major difference between waterfall and iterative model is that waterfall model has a linear process in which full product is available after the last phase, while incremental model full product is available after several such phases.

•Software Project Tracking and Control (Assess progress and take action to maintain commitment)

•Risk Management (Assess risks that will affect outcome and quality)

•Software Quality Assurance (Define and conduct activities to ensure software quality)

•Formal Technical Reviews (Assess Work products to uncover and rectify defects)

•Measurement (Define and collect process, project and product metrics)

•Software Configuration Management (Manage effect of change)

•Reusability Management (Define criteria and establish mechanisms for reuse)

•Work Product Preparation and Production (Activities required to create the work products)

* Prototyping includes more customer attention or intraction rather than waterfall model. * Prototypes have a model to study and work, where waterfall do not have any model till last, what ever we developed that comes in last.

what about electronics & telecommunication?

I my opinion electrical is best!

Yes, waterfall model is non applicable in some areas. Reason being that we can not go back to the previous stage if we missed something , we have to restart the process.

The Spiral model consists of four main task regions: Planning, where project objectives and constraints are defined; Risk Analysis, which involves identifying and mitigating potential risks; Engineering, where the actual development and coding take place; and Evaluation or Customer Evaluation, where the product is reviewed and feedback is gathered for future iterations. These regions are repeated in cycles, allowing for continuous refinement and improvement of the project.

Of course not. Millions of people go about their lives every day without any knowledge of software engineering.

A thread is the sequence of instructions followed by a CPU, and is an independently dispachable unit in the run queue. A process can start and manage multiple threads, each managing an aspect of the overall processing. The operating system can schedule the threads independently, allowing them CPU time if they are ready, or blocking them if they are waiting on something, such as an IO completion. In a network process, such as a web server, there can be many things going on at the same concurrent time. Threads are an ideal solution to the problem of managing all of these things, because the main process does not need to poll each sub-process (thread) to see if it needs or is ready to do work.

Gatik-SMS is a product from Gatik Business Solutions - a privately held business group headquartered in the silicon valley of India, Bangalore. From a two-member founding team a decade ago, Gatik has grown into a multi-million dollar enterprise, with interests in diverse industries like home automation, software, broadband and other services. By virtue of our broadband and other technology businesses, Gatik has acquired immense knowledge in technology solutions built on cloud and managed remotely. This expertise has helped in developing the next generation tool like Gatik-SMS for education domain. Click Here

The inverter, which returns the reverse of the input. The AND gate which returns a high output if and only if both inputs are high. The OR gate, which returns a high output if either or both inputs are high. The NAND and NOR gates return the opposite of their counterparts. They are basically the AND and OR gates with an inverter after them. The XOR gate is the exclusive OR gate; it returns a high output it either input is high, but not both. Every binary combination of outputs can be made from these operators. In fact, you don't even need all of them. The NAND and the NOR gate can both create every other gate.
