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.
Answer:
D. It is a program that checks for grammatical errors.
Answer:
101.1
Explanation:
Keep in mind that octal has 8 numbers
Step 1: Split your number in 2 parts (integer part and decimal part):
- integer part 65
- decimal part 0.125
Step 2: Convert the decimal part. For this step you need to multiply your decimal part and 8 (8 correspond the octal base) and get the integer part until you need it:
0.125 * 8 = 1
So your decimal part correspond to number 1 in octal = (1)8
Step 3: Convert integer part: for this step you need to divide your integer part by 8 until you can and get the remainder
65 / 8 = 8 remainder 1
8 / 8 = 1 remainder 0
1 / 8 = 0 remainder 1
Step 4: join the remainders from bottom to top and get the integer part
101
Step 5: join the integer part and the decimal part to get the octal convertion
101.1
Answer: (A) Tactical support
Explanation:
GIS is the global information system in which the data is delivered worldwide in the form of information system. The global information system achieve long term goals in an organization.
- The tactical support is used in the global information system for concentrating the activities on the medium range in an organization.
- The tactical support is one of the effective way to producing the desirable result and also achieve the main strategic objective.
Therefore, Option (A) is correct.
