What does a software engineer do apart from producing software?
While most people think of a "software engineer" only as the person who sits around and writes code, this job is actually much more complex.
Software engineers must see a software product through its whole lifecycle. This starts with some idea a customer has, goes through multiple stages each of: gathering requirements, setting formal specifications, implementation, testing, and maintenance.
What do you understand by severity and priority of a defect?
Severity and Priority are the attributes of a defect. If we talk about 'Severity of a defect' then it describes how the defect is impacting the functionality of software product whereas 'Priority of a defect' indicates the importance of the defect and when it should be addressed or fixed.
- In the software project, the severity of a defect should be defined by QA whereas the priority should be defined by Product Owner.
- Severity of the defect can be categorized into four levels: blocker, critical, major & minor. Similarly, Priority of the defect can be high, medium & low.
What are some ways to compose or develop a paragraph?
There are many ways to begin writing - I usually recommend just making a list of everything you know and turning the facts into sentences.
Here are some more formal ways to start thinking about your paragraph:
- Analogy - list ways that your topic is like something else
- Analysis - explain how your topic works in detail
- Anecdotes - tell a story to explain your topic
- Cause and Effect - explain how your topic causes other things to occur; OR explain how your topic is caused by other things
- Classification and Division - list all of the things that go into your topic
- Compare and Contrast - list all the ways in which your two topics are alike and all the ways in which they are different
- Definition - list each definition for your topic (you can also list things which your topic is NOT, which is called Elimination, but this is seldom used)
- Description - list everything you can use to describe your topic
- Enumeration - list a set of observations about your topic
- Exemplification - list all of the examples of your topic
- Facts - list all of the facts you have looked up about your topic
- Narration - list the events that make up your topic in chronological order
- Persuasion - list arguments that might make a reader take an action or believe in your opinion
- Process - describe step-by-step how the actions in your topic may be carried out in sequence
- Statistics - list all of the statistics you have looked up about your topic

- etc. application specific classifications of input

Planning is looking ahead and control is looking back?
Planning is Looking Ahead is true because it contributes heavily to success and gives us some control over the future. By, planning we set aside our tasks and deadlines so we can enlarge our mental focus and seeing the bigger picture. By, planning we can set our Personal or organizational goals and for this defiantly we have to look ahead.
But, Planning is not ending with such strategies or guidelines. It has relation with Implementation and controls. Because plans are not always proceed as conceived. The control process measures progress towards goal attainment and indicate corrective action if too much deviation is detected.
Controlling investigates whether planning was successful.
Controlling referred to as terminal management function, takes place after the other functions have been completed. And for this process we have to look back and have to analyze the performance of our planning, organizing and leading. And therefore we have to look back also.
So, yes we can say Control is looking back for Investigation, Analysis, and Understandings and for checking our effectiveness and efficiency.
What are the five components of a design method?
The design method is used in a variety of fields. The common thread is the steps used in the method. It includes situation, research, ideaton, development and realisation.
Why do menu-driven interfaces continue to be popular in the modern computing age?
Menu-driven interfaces continue to be popular because they are easier to figure out and work with than command-line interfaces, with frequently cryptic and hard to recall commands and option selections.
What is the difference between level 0 DFD and level 1 DFD?
"If you go through a Kendall and Kendall's Book it shows Context Level and Zero "0" Level as a different level DFD. According to Book by James A. Senn Both are same.
So, Whatever method you follow just mention the reference you have taken from that book.
From my point of view James A. Senn's book have clear and Correct approach toward DFD."
Ref: dataflowdiagram.blogspot.in/2010/04/common-mistakes-in-dfd.html
The level 1, called context DFD, shows the whole system in one process. Level 2 focuses more closely on one particular process in level 1, and level 3 focuses on a single process from level 2.

Difference between verification and validation in software testing?
verification: Are we doing the right system?
validation : Are we doing the system right?
What are the requirements for prototype?
The requirements for a prototype typically include a clear definition of the problem it aims to solve, specifications of the desired features and functionality, and the materials or resources needed for its construction. Additionally, it should have a defined scope, including any constraints such as budget and time limits. Finally, user feedback mechanisms should be in place to evaluate its effectiveness and guide future iterations.

What is the difference between G code and M code in CNC programming?
Generally G codes are writen in and performed by the CNC processor and operate the motion control part of the control, the M codes are MACHINE codes, these operate most of the basic electrical control functions such as Coolant, Tool changers, safety circuits etc, the M,S & T codes are written in a separate PLC processor, both processors usually communicate with each other over a common bus.
The tool changer and spindle are both configured to suit a particular machine specifics.
