A hard copy is the digital file, stored in a device and was printed out. A soft copy is the electronic version NOT PRINTED. It is showcased digitally (through a phone, computer, flash drive etc)
Answer:
The correct option is B.
Explanation:
Memory hierarchy is the ordering of storage systems according to their speed, capacity and cost.
The hierarchy consist of Register as the top, followed by cache, then main memory, secondary memory and external storage. As you go down the hierarchy, the speed decreases, the size increases and the cost decreases also.
Memory hierarchy diagram is attached for reference.
Answer:
D. Left,left
11 is less than 20 as well as it is less than 25 years. And we move from left to right on the timeline. Thus 11 is left of 20 and it is left of 25 years as well. And timeline is the core of a project management software. The Gantt and Pert chart are totally based on the timeline. Software like Microsoft project use the timeline quite a lot, and you cannot survive without the knowledge of the timeline in software project management.
Explanation:
Timeline knowledge is a must for a software professional, and the above answer does not require explanation.
Answer:
B. Incremental Build life cycle
Explanation:
RAD life cycle: RAD model of software development life cycle is all about coming up with prototype as soon as possible. It describes a method of software development which heavily emphasizes rapid prototyping and iterative delivery.
Incremental build life cycle: In incremental build model of software development life cycle, each release of the software have added capabilities. The development is finished when the user is okay with the present features. Focus is put on creating a working prototype first and adding features in the development life cycle. This is the correct option.
Waterfall life cycle: In a waterfall model, each phase must be completed fully before the next phase can begin and this usually takes time before a working software can be released. There is also no overlapping in the phases.
Spiral life cycle: Spiral Model can be pretty costly to use and doesn't work well for small projects. It's a risk-driven model which means that the overall success of a project highly depends on the risks analysis phase.
