Answer:
True is the correct Answer for the above question.
Explanation:
- Computer security is a security in which data of the computer is secured from the access of unauthorized users. It is primarily achieved to stop the access grant to the unauthorized user.
- It means that there is an authorization point which decides that the user is authorized or not. If the user is authorized then only he can enter the system otherwise he can not able to enter the system.
- It helps to secure the data and the data is the important point of the computer system.
- The question also states the same which is described above. Hence true is the correct answer.
Answer:
Incremental method.
Explanation:
Software development life cycle (SDLC) can be defined as a strategic process or methodology that defines the key steps or stages for creating and implementing high quality software applications.
An incremental model refers to the process in which the requirements or criteria of the software development is divided into many standalone modules until the program is completed.
Hence, an incremental method typically involves developing a system through repeated cycles and smaller portions at a time, enhancing and evolving the system over time.
In SDLC, a waterfall model can be defined as a process which involves sequentially breaking the software development into linear phases. Thus, the development phase takes a downward flow like a waterfall and as such each phase must be completed before starting another without any overlap in the process.
Also, a spiral model can be defined as an evolutionary SDLC that is risk-driven in nature and typically comprises of both an iterative and a waterfall model. Spiral model of SDLC consist of these phases; planning, risk analysis, engineering and evaluation.
Answer:
The correct option is Option B
Explanation:
We need to find examples of client-side code.
Client Side code: The part of code, that doesn't require server for performing specific task
SO, The correct option is Option B
Prompt for special characters in user name
Reason: We can use alert to generate prompt using JavaScript or through validation and it can be done on client side.
All other options, we need to hit the server to perform the task, So they are not client-side code.
The underscore.
But actually you can use spaces in file names, in many file managers. I think it just shows you a space while it actually saves an underscore, or something like this.
