Answer:
Playfair Cipher.
Explanation:
Encryption is a form of cryptography and typically involves the process of converting or encoding informations in plaintext into a code, known as a ciphertext. Once, an information or data has been encrypted it can only be accessed and deciphered by an authorized user.
Some examples of encryption algorithms are 3DES, AES, RC4, RC5, and RSA.
The best known multiple letter encryption cipher is the Playfair Cipher, which treats digrams in the plaintext as single units and translates these units into ciphertext digrams.
In the Playfair Cipher, a 5 × 5 matrix comprising of letters is developed using a keyword and then, the matrix is used to encrypt the plaintext as a pair i.e two letters at a time rather than as a single text.
Answer:
The correct answer to the following question will be "Restore Points ".
Explanation:
A restore point in a system is an image of configuration and Microsoft Registry settings that manage to system restore to such an earlier stage once the system was functioning correctly.
- You could automatically build a restore point from Device Assets window on the System Security page.
- System restores up to around 100 GB is expected to be used, says it uses about 13.5 GB at the time.
So, the Restore points is the right answer.
It won't let me post. Please see the comments on this answer for the answer.
Answer:
1) 2 bits 2) shown in explanation 3) shown in explanation 4) 22 bits per pixel (2.75 bytes)
Explanation:
As a bit is one of two states, 1 or 0, 2 bits is sufficient to represent 4 colors:
00 = color 1
01 = color 2,
10 = color 3,
11 = color 4
This would be the custom type of encoding for that specific image as it only uses 4 colors.
Now to calculate the amount of memory saved, which is quite simple:
24-2=22
So you Would save 22 bits per pixel or 2.75 bytes per pixel.
Embedded system is considered any computer system that isn't a general-purpose pc or server.
<h3>What is an embedded system?</h3>
An embedded system is a combination of computer hardware and software designed for a specific function. Embedded systems may also function within a larger system. The systems can be programmable or have a fixed functionality.
<h3>What is embedded system and its types?</h3>
Embedded systems comprise hardware and software that work together to perform specific tasks. They rely on microprocessors, microcontrollers, memory, input/output communication interfaces, and a power supply to function
