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.

Answer:
Reverse factoring, also called supply chain finance, works in the opposite direction of invoice factoring. Instead of a company factoring customer invoices, it factors supplier invoices. In doing so, the company is factoring part of the supply chain. Reverse factoring is an accounts payable solution.Aug 28, 2019
Explanation:
Answer:
A) 2.56 ms
B) 128 μs
Explanation:
Time for Bus cycles = 500 ns
Transfer of bus control = 250 ns
I/0 device data transfer rate = 50 KB/s
Data are transferred at : 1 byte at a time
A) Determine how long the device tie up the bus when transferring a block of 128 bytes
Block size to be transferred = 128 bytes
Bandwidth = 50 KB/s
data transfer = (Block size ) / ( Bandwidth)
= ( 128 * 8 ) / ( 50 * 10^3 * 8 )
= ( 1024 ) / ( 50 * 10^3 * 8 )
= 2.56 ms
To determine the actual transfer time we have to add up the transfer time for the bus control in both directions :
2.56 ms + 500 ns = 2.56 ms. this is because 500 ns is not a significant value
B) cycle stealing mode
In this mode each byte is transferred at a time and The total transfer time needed for the bus control in both directions will be double the total time i.e 2 * 500 ns = 1000 ns. because additional control time of 250 ns is required at both ends
since 1 byte is transferred at a time , 1 byte will be transferred in 1 μs
128 bytes = 128 * 1 μs = 128 μs
