Because it manages all other software the computer which software is most important

Wewaii [24]

Answer: second option: Operating system...

An operating system is the most important software that runs on a computer. It manages the computer's memory and processes, as well as all of its software and hardware. It also allows you to communicate with the computer without knowing how to speak the computer's language.

Hope this helps... Stay safe and have a Merry Christmas!!!!!!! :D

Compare AES to DES. For each of the following elements of DES, indicate the comparable element in AES or explain why it is not n

Setler79 [48]

Answer:

See explaination for the comparison

Explanation:

Comparison Of AES & DES:

DES(Data Encryption Standard)

In DES the data block is always been divided into two of the halves.

It works on the Feistel Cipher Structure.

The plaintext is of the 64 bits.

DES has 16 rounds in it.

The rounds that are in DES are as follows:

Expansion

Permutation

XOR

S-box

P-box

Swap

DES has a smaller key which is less secure as compared to AES

In speed, the DES is comparatively slower.

AES(Advanced Encryption Standard)

In AES the entire data block is always processed as a single matrix.

It works on the principle of substitution and permutation.

The plaintext in AES varies from 128 bits ,192 bits, 256 bits, etc.

AES has a larger key size as compared to the DES.

There are many variations to the rounds in AES and is dependent on the bits of the encryption.They are as follows: 128-bits algorithm consists of 10 rounds. 192-bits algorithm consists of 12 rounds. 256-bits algorithm consists of 14 rounds.

The names for the rounds are as follows:

Subbytes

Shiftrows

Mix Columns

AddRoundkeys.

AES is having large secret key comapratively to the DES which is more secure.

Comparing the speed for the encryptions AES is faster than DES.

a.) AddRoundKey

b.) Since AES is not Feistel cipher this step is not essential.

c.) ByteSub is there.

d.) ShiftRow and MixColumn

e.) No swaping of halves

How to write an inequality on a computer?

Artyom0805 [142]

For all numbers, be sure to use the keypad (on the right end of the keyboard), not the number keys (along the top of the keyboard).

≥ Hold down the Alt key, then type 242. 
≤ Hold down the Alt key, then type 243 

For ≅, ≟, ≠, you need to use the Character Map.

Integrated circuits incorporate many transistors and electronic circuits on a single tiny silicon chip, allowing ____ to be even

olga55 [171]

Integrated circuits incorporate many transistors and electronic circuits on a single tiny silicon chip, allowing Third generation computers to be even smaller and more reliable than earlier computers.

<h3>What are the Third generation computers?</h3>

The Third generation computers are known to be a kind of a computers that was said to have came about as a result of the growth and development of the integrated circuit (IC).

Note that they are said to be the first steps toward computers and as such, the Integrated circuits incorporate many transistors and electronic circuits on a single tiny silicon chip, allowing Third generation computers to be even smaller and more reliable than earlier computers.
