Software Process and it's characteristics and activities

By Kajal Vishwakarma -
Q) Describe the important characteristics of a software process.
Q) Explain software process. Enumerate the activities common to all software processes. Also list the characteristics of software processes.

Ans) Software Process:- A software process is a set of activities, together with ordering constraints among them, such that if the activities are performed properly and in accordance with the ordering constraints, the desired result is produced. The desired result is high quality software at low cost.

There are four fundamental process activities which are common to all software processes. These activities are-
1) Software Specification
2) Software Development
3) Software Validation
4) Software Evolution

1) Software Specification:- The functionality of the software and constraints on its operation must be defined.

2) Software Development:- The software to meet the specification must be produced.

3) Software Validation:- The software must be validated to ensure that it does what the customer wants.

4) Software Evolution:- The software must evolve to meet changing customer needs.

Characteristics of Software Process:-
The main objective of process is same as that of software engineering, namely optimality and scalability. Optimality defines the process should be able to produce high quality software at low cost, while scalability means that it should also be applicable for large software projects. So, process should have some desirable characteristics to achieve the objectives, which are as follows-
1) Predictability
2) Testability and Maintainability
3) Early Defect Removal and Defect Prevention
4) Process improvement

1) Predictability:- Predictability can be considered as a fundamental property of any process. Predictability of a process determines how accurately the outcome of following process in a project can be predicted before the project is completed. If a process is not predictable, then it is of limited use.
A predictable process is under statistical also called as under statistical control. Statistical control implies the prediction for a process, which are generally based on the past performance of the process, are only probabilistic. A Predictable process is an essential requirement for ensuring good quality and low cost.

2) Testing and Maintainability:- One of the important objectives of the development project should be to produce software that is easy to maintain and the process should be such that it ensures this Maintainability.
The goal of the process should not be to reduce the effect of design and coding, but to reduce the cost of testing and maintenance. Both testing and maintenance depend heavily on the design and coding of software, and these costs can be considerably reduced if the software is designed and coding to make testing and maintenance easier.

3) Early Defect Removal and Defect Prevention:- In this section, the main moral is that, we should attempt to detect errors that occur in a phase during that phase itself and should not wait until testing to detect errors. In reality, sometimes testing is the sole point where errors are detected. Besides the cost factor, reliance on testing as the primary source for error detection, due to the limitations of testing, will also result in unreliable software. Error detection and correction should be a continuous process throughout the software.

4) Process Improvement:- The process is not a static entity. The fundamental goals of any engineering discipline are improving the quality and reducing the cost of products.

Protocol verification using finite state machine model in computer network

By Kajal Vishwakarma -
Protocol Verification Using Finite State Machine Model:- The finite state machine is a mainly used in several protocol models with this technique, every protocol machine is always in a particular state at every time instant. Variables, including the program counter. From every state, there are zero or more possible transition to other states. When some event happens, transition take place. In case of a protocol machine, a transition might take place if a frame is transmitted, if a frame arrives, if a timer expires, if an interrupt takes place, etc. One particular state is designated as the initial state. This state corresponds to the description of the system when it starts running, or at some convenient starting place shortly thereafter. From the initial state, some, perhaps all, of the other states may be approached by a sequence of transition. this technique is called reachability analysis. This analysis can be helpful in determining whether a protocol is correct. All processes are
