Answer: D
Within a specific time period or by a specific user
Explanation:
All data is encoded in binary––1 (status of on) and 0 (off status). Color images are composed of group of color, with different amounts of red, green, and blue (ranging from zero to 255). Different values of these colors make up a single pixel. Thus, Image files contain millions of these color combinations. Each color channel is represented by eight bits. Eight bits = 1 byte. One color channel, red, green, or blue is represented by 8 bits or one byte. For example, blue is 01100110.
Answer:
- The leftmost 1 in 101 gives the 4.
- 1 in 101 (using binary system) gives the bits that must be counted to make a decimal number.
Explanation:
While working on binary system, we represent the decimal digits (0-9) by using only two digits 0's and 1's. They are written by dividing the decimal digit by 2 and then recording the remainder bits in reverse order.
As given in the question 5 is represented in binary as 101.
Now converting binary to decimal:
- The bits of binary number are multiplied by increasing powers of 2 (starting from the right) and added to get decimal value.
- So the binary number 101 will be interpreted as:
- So the leftmost 1 will show the presence of 4.
- 1 in the number 101 shows which bits will be weighted to give the required value.

Answer:
D.
Explanation:
Based on the information provided surrounding this scenario, it can be said that the most likely next course of action would be to create an alternate user ID to maintain persistent access. This would allow the attacker to have continuous access into the network in the case that the system administrators detect that the operator's user ID and password have been compromised. Thus also giving the attacker ample time to infiltrate and find vulnerabilities in the network through an alternate hidden user ID.
