A computer has a memory ________, rather than just a single memory component. The lowest level is some form of ________ storage

oksian1 [2.3K]

Answer:

A computer has a memory hierarchy, rather than just a single memory component. The lowest level is some form of secondary storage such as a magnetic disk. The next level is the main memory where a subset of the data from the hard disk is stored temporarily. The cache memory is the next level and uses SRAM to store frequently used data. Finally, the register store variables and temporary results for the current CPU computations.

Which biometric technique is considered nearly infallible from a scientific point of view and is increasingly preferred by crimi

Sergio039 [100]

Answer:

DNA analysis

Explanation:

DNA is unique for all individuals. DNA analysis is the process of analysing the DNA characteristics of an individual.

DNA profiling is used in forensics to identify the suspects involved in criminal activities.

1. In the process, DNA of the suspects is matched with the DNA found in the site of the crime.

2. If a match is found, it indicates that the genetic relationship exists between the suspect and the criminal or the crim.

3. The order from the court is needed to obtain the DNA of the suspects. The sample can be in the form of blood or saliva.

4. The sample obtained should have adequate cells which contain the DNA.

Issues

The DNA obtained from the crime site is not pure or proper enough to be ideal for the DNA profiling.

Degraded sample

1. The sample obtained from the site of the crime is not always adequate to obtain the actual DNA.

2. The sample can be contaminated due to the environmental factors.

3. The sample obtained is too less and hence, should be examined accurately in order not to waste the sample.

DNA mixture

4. The sample obtained from the site of the crime is found to contain DNA from more than one individual.

Profiling types

DNA profiling can be carried out by using any of the techniques mentioned below.

1. RFLP analysis ( Restriction fragment length polymorphism )

This uses the Southern blot technique. The blot process needs a large amount of the sample. Also, this works well only when the sample is not degraded.

2. Polymerase chain reaction (PCR) analysis

3. STR analysis ( short tandem repeats )

4. AFLP ( amplified fragment length polymorphism )

This is an automated and low-cost process. It is easy to set up and operate which makes this process common in low income countries.

All the methods mentioned above have their own advantages and drawbacks.

Your baby brother has found the hammer and is eagerly eyeing one of the boxes. Describe and analyze an algorithm to determine if

erastovalidia [21]

Answer:

Question is incomplete.

Assuming the below info to complete the question

You have a collection of n lockboxes and m gold keys. Each key unlocks at most one box. Without a matching key, the only way to open a box is to smash it with a hammer. Your baby brother has locked all your keys inside the boxes! Luckily, you know which keys (if any) are inside each box.

Detailed answer is written in explanation field.

Explanation:

We have to find the reachability using the directed graph G = (V, E)

In this V are boxes are considered to be non empty and it may contain key.

Edges E will have keys .

G will have directed edge b1b2 if in-case box b1 will have key to box b2 and box b1 contains one key in it.

Suppose if a key opens empty box or doesn’t contain useful key means can’t open anything , then it doesn’t belongs to any edge.

Now, If baby brother has chosen box B, then we have to estimate for other boxes reachability from B in Graph G.

If and only if all other boxes have directed path from box B then just by smashing box B we can get the key to box b1 till last box and we can unlock those.

After first search from B we can start marking all other vertex of graph G.

So algorithm will be O ( V +E ) = O (n+m) time.

What will the following code print out: int numbers [] = {99, 87, . 66, 55, 101}; for (int i = 1; i < 4; i++) cout << n

forsale [732]

Answer:

87 66 55

Explanation:

Array is used o store the multiple values with same data type.

the array show a decimal value .66, i assume this is enter by mistake because option has no decimal value.

The index of the array is start from zero, it means the first element store in the array at position zero.

In the for loop the variable 'i' start from 1 not zero and it goes to i<4 means i=3.

So, it access the element from 2 to 4 because the index is position of element less than 1.

Therefore, 87 66 55 print.

13) When developing film, how do you dispose of fixer as opposed to developer?

MAVERICK [17]

Answer:

B) Developer is poured down the drain while fixer can be reduced

Explanation:

The effluents produced during photographic processing includes, wash water, bleach, fixer, and developer

The developer is an alkaline solution, with a pH of approximately 10.0, while the pH of the fixer is about 4.3, it is therefore, acidic

The rate of discharge of the developer to the fixer is 2 to 1, and the exhausted developer, fixer and process effluents combined are neutral and can be handle by the the treatment works and the drain pipes

Fixer which remain clear can be reused for more than a day, while the spent basic Developer and the acidic Spent Stop Bath can be combined to form a neutral solution, having a pH of approximately 7, which make them less hazardous to be disposed off down the sink into the drain

Therefore, <em>developer is poured down the drain while fixer can be reused</em>
