You have developed a prototype of a software system and your manager is very impressed by it. She proposes that it should be put

into use as a production system, with new features added as required. This avoids the expense of system development and makes the system immediately useful. Write a short report for your manager explaining why prototype systems should not normally be used as production systems.

Answer:

Explanation:

Talking about prototype model, we can say that, it is developed by knowing the requirments.

A client Interaction with prototype makes the client to have the ability to get the feel of system.

It is best for large systems as this helps to determine the requirements. It is not complete, this is because many of its details are yet to be built. Users also involved in its development.

Production system is a result of organizing inputs, then process is carried out and then output is based on some logic and functions. Production system fails if any such arrangement made don't give a desired level of outcome.

If requirments are missed then prodution system may fail. So prototype systems are not used as production systems.

<h3>What is a code in programming?</h3>

In laptop programming, laptop code refers back to the set of instructions, or a device of rules, written in a specific programming language (i.e., the supply code). It is likewise the time period used for the supply code after it's been processed via way of means of a compiler and made equipped to run at the laptop (i.e., the item code).

<h3>What is DRAM?</h3>

DRAM was invented in 1968. It is a type of RAM used in modern computers and laptops. It is a type of random access memory. Its name is dynamic random access memory.

Metal-oxide-semiconductor is used in making the transistors and capacitors of the DRAM, which are used to store the data. They hold a bit of the data in these capacitors and transistors.

Thus, the material that is used is metal-oxide-semiconductor to make DRAM (dynamic random-access memory).
