Answer: 1,500,000 bytes.

Explanation:

If we assume that we have an image of 4000 pixels (picture elements) wide, by 3000 pixels height, a complete uncompressed image will be represented by 4000*3000= 12,000,000 pixels.

Now, if we are talking of a binary image, this means that each pixel will have, as a maximum, two possible values, so we will need only one bit per pixel.

This means that we will need to store 12,000,000 bits.

As we know, 1 byte=8 bits.

So, we will need 12,000, 000/8 bytes ⇒ 1,500,000 bytes in order to store an uncompressed binary image of size 4000 x 3000 pixels.

OLEGan [10]

DES is a commonly used symmetric encryption

A) is a commonly used symmetric encryption

<u>Explanation:</u>

DES stands for Data Encryption Standard. It is a symmetric key algorithm and is used for encrypting electronic data. It was developed in 1975. DES is one of the oldest encryption standards to be used in the industry.

The algorithm takes 16 rounds of permutations in order to encrypt data. But now, with the advent of technology, as new algorithms have been designed and put in use, DES is less preferable.

In the process of key generation, some keys generated sometimes turn out to be weak and hence are prone to attacks. If not for the weak keys generation, DES works perfectly fine and is an effective algorithm to encrypt data.

Which method tries all possible passwords until a match is found?

barxatty [35]

Brute force is this approach to password cracking. It tires all possible password combinations until a correct match between the hashes is found. It may make use of rainbow tables which contain precomputed password-hash combinations.

Please remember that it helps to provide the choices that match your question. This can help you get an accurate answer and have your question answered much quicker.

If an Administrator performs a clean install of Windows Server 2012 R2 on a new server, and then moves critical domain services

gayaneshka [121]

Answer:

The correct answer to the following question will be "Server role migration".

Explanation:

A process of moving data from one data to the next. Security concerns are the causes behind the system relocation, the hardware is also being changed and several other influences.
With this, you are setting up a new server, either virtual or physical, running a new version of Windows (Windows Server) and then moving your positions and facilities to the newly constructed Windows Server Virtual Machine/Physical.

Therefore, it's the right answer.
