Software Verification and validation are the processes in which we check a product against its specifications and the expectations of the users who will be using it.
It is possible that software is verified but not validated because during the requirements engineering phase, user needs might not have been captured precisely or the analyst might have missed a major stakeholder in the analysis.
Now, let’s suppose during requirement engineering phase, users requirements are captured precisely and comprehensively. Do you think there is a need of validation? Is it a wastage of resources if we perform validation in said scenario?

Pipelining is a popular technique widely used in computer architecture that provides the support of instruction parallelism. Suppose that, five different instructions are going to be executed at different stages of the pipeline, e.g. stage 1 have one instruction, stage 2 have other instruction and so on. Further, assume that, these instructions can execute in parallel at different stages of the pipeline and the size of instructions can vary.
Keeping in view the dependency and the size of each instruction from the above scenario, which instruction will execute first from the different stages of pipelining given below?
Stage 1: Instruction fetch -> Instruction 1
Stage 2: Instruction decode -> Instruction 2
Stage 3: ALU operation -> Instruction 3
Stage 4: Memory access -> Instruction 4
Stage 5: Register write -> Instruction 5

We have to send MUMPS code and screenshot from the execution, or if you don't have MUMPS, maybe if someone help me write the code , I can try to run on mine, but it keep giving me error message everytime I try to run
thanks so much, I am new to this and slow at learning!!

What is the required criteria for the heuristic function for the A star tree search to be optimal?
Why is it better to use heuristics with higher values? Assume admissble heuristic.
What's the main advantage of using heuristic search over blind search?
1. What are the main differences between the three I/O models and what are their strength and weakness?
2. Assuming that an application needs to output 1000 words from the internal memory to the hard disk, calculate the following values for each I/O model:
- How many times the processor is interrupted?
- How many times the memory is read by the processor (for both program and data)?
- How many times the disk controller is read by the processor?
- How many times the disk controller is written to by the processor?

You are the manager of a software development company. The GreenLineBus.in is an transport company and they want to create an on-line portal to do the following activities : 1) booking, cancellation, payment and refund. Assuming suitable Input, Output ,Query features and file system, Compute Estimated unadjusted Function Point count as follows:
a) List type of Input, output counts, File names, query and interfaces. Tabulate them into simple, medium and complex.
b) Tabulate Unadjusted function points giving a total of them
You can assume some data points or features as appropriate to drive your point.
