7 0

Answer:

continual user involvement gives the flexibility to analyze the requirements in right direction. because there is continuous meetings with the end user and he can provide right direction or avoids wrong interpretation of the requirement

)Dynamically allocate an object of Banana, using the pointer variable daco.
zepelin [54]

Answer:

d) daco = new Banana;

Explanation:

Dynamically allocated variables have their memory allocated in the heap memory.We declare a dynamical variable like this:-

int *a=new int ;

It means a pointer a is created on the stack memory which hold the address of the block that hold the value of variable a in heap memory.

We already have the pointer daco. We just have to initialize with keyword new.

It will be like daco=new Banana; which matches the option d.

true or false? in a known-plaintext attack (kpa), the cryptanalyst hs access only to a segment of encrpted data and has no choic
bulgar [2K]

Yes , it’s true. In a known-plaintext attack (kpa), the cryptanalyst can only view a small portion of encrypted data, and he or she has no control over what that data might be.

The attacker also has access to one or more pairs of plaintext/ciphertext in a Known Plaintext Attack (KPA). Specifically, consider the scenario where key and plaintext were used to derive the ciphertext (either of which the attacker is trying to find). The attacker is also aware of what are the locations of the output from key encrypting. That is, the assailant is aware of a pair. They might be familiar with further pairings (obtained with the same key).

A straightforward illustration would be if the unencrypted messages had a set expiration date after which they would become publicly available. such as the location of a planned public event. The coordinates are encrypted and kept secret prior to the event. But when the incident occurs, the attacker has discovered the value of the coordinates /plaintext while the coordinates were decrypted (without knowing the key).

In general, a cipher is easier to break the more plaintext/ciphertext pairs that are known.

Which statement best justifies the use of a high-speed cache in a CPU?
crimeas [40]

Cache memory is a high-speed memory that stores the instructions and data that have been frequently accessed.  It decreases the time it takes to decode the instructions stored in the instruction pipeline.

A.  It decreases the time it takes to decode instructions stored in the instruction pipeline.

<u>Explanation:</u>

Whenever an instruction is invoked or some data is accessed, the CPU looks for it in the cache memory before accessing the main memory.

If the content is found in the cache memory, it accessed from there and then and hence the access time and decode time is reduced as there were no main memory lockups.
