9. Does software wear & tear by decomposition ? Explanation: Unlike hardware, software is reliable.
Does software deteriorate?
Software rot, also known as bit rot, code rot, software erosion, software decay, or software entropy is either a slow deterioration of software quality over time or its diminishing responsiveness that will eventually lead to software becoming faulty, unusable, or in need of upgrade.
What are the characteristics of the software?
Characteristics of Software are classified into six major components:
- Functionality: …

What are the 3 categories of software?
And as we discussed there are broadly three types of software i.e. system software, application software, and programming language software. Each type of software has its function and runs on the computer system.
What are the two main classifications of software?
Computer software is typically classified into two major types of programs: system software and application software. Systems software are programs that manage the resources of the computer system and simplify applications programming.
What is the meaning of software does not wear out?
Software is not susceptible to the same environmental problems that cause hardware to wear out. … During its life, software will undergo changes and it is likely that some new defects will be introduced as a result of this, causing the failure rate curve to spike as shown above.
How do you prevent software rotting?
Preventing Software Rot – Maintaining Code Quality & Sanity Over Time
- Scrub Your Requirements. When specifying a feature of an application, it’s tempting to jump to the implementation. …
- Automate Tests and Run Them. …
- Trim the Fat. …
- Leave Breadcrumbs…
Why software doesn’t wear out but deteriorate explain with an example?
Software doesn’t “wear out”. It takes the form of an idealized curve. Undiscovered defects will cause high failure rates early in the life of a program. These are corrected and the curve flattens ● Software doesn’t wear out ,but it does deteriorate.
What is the major drawback of core?
What is the major drawback of CORE ? Explanation: In CORE the requirement specification are put together by all users, customers and analysts, so a passive analyst will not get the requirements properly.
What is the major drawback of using RAD model?
What is the major drawback of using RAD Model? Explanation: The client may create an unrealistic product vision leading a team to over or under-develop functionality. Also, the specialized & skilled developers are not easily available.
Which is not a software process quality?
Which one of the following is not a software process quality? Explanation: Portability is a software product quality which means software can run on different hardware platforms or software environments. 2. … Explanation: Cost of a software is a management issue & is not related to process activities.
What are the types of requirements?
The main types of requirements are:
- Functional Requirements.
- Performance Requirements.
- System Technical Requirements.
- Specifications.
Which of the following is not necessary to apply agility to a software process?
8. Which of the following does not apply to agility to a software process? Explanation: Testing is a major part of each software development process which can’t be avoided.
Which of the following activity is included in software maintenance?
Description: Software maintenance is a vast activity which includes optimization, error correction, deletion of discarded features and enhancement of existing features. Since these changes are necessary, a mechanism must be created for estimation, controlling and making modifications.
Does code degrade over time?
Code rot is the degradation of the code base over time. The gradual decay (type 2) is the more difficult case. It is both hard to spot and hard to combat, since it happens bit by bit. However, if not dealt with in time, it is quite hard to fix.
Does data degrade over time?
In storage
Data degradation results from the gradual decay of storage media over the course of years or longer. … Magnetic media, such as hard disk drives, floppy disks and magnetic tapes, may experience data decay as bits lose their magnetic orientation.
What is the meaning of bit rot?
Bit rot, also called “format rot,” is the inability to access digital data because hardware and software do not exist to read the format. For example, files saved on tape cartridges might not be retrievable because the drives are not available.
What does SDLC stand for?
Software Development Life Cycle (SDLC)
Why is software important today?
Software is truly powering our world; it enables the functionality of our banks, power plants, communication and combat equipment. Hospitals, medical devices and critical infrastructure, such as 911 systems and the electric grid, all depend on software to operate effectively and efficiently.
What is software short?
Software is a set of instructions, data or programs used to operate computers and execute specific tasks. It is the opposite of hardware, which describes the physical aspects of a computer. Software is a generic term used to refer to applications, scripts and programs that run on a device.
