what is an advantage of using electronic databases for research? they provide only the most up-to-date information. they provide smaller, more manageable amounts of information. they provide bibliographic information, abstracts, and full-text documents.

Since the company hires security experts to play the role of hackers. the experts are asked to attempt to breach the infrastructure to determine how secure the company is from threats. the experts are also asked to recommend improvements. This activity is called  penetration testing.

Penetration testing, also known as ethical hacking or pen testing, is the authorized simulation of a cyberattack on a computer system that is carried out to examine the system's security. This is distinct from vulnerability assessments.

Therefore, Penetration testing, often known as pen testing, is seen as a form of a security exercise where a cyber-security specialist looks for and attempts to attack weaknesses in a computer system. By simulating an attack, it is possible to find any security gaps that an attacker might exploit.

The 802.11 protocol is designed to detect and resolve conflicts between stations when two devices attempt to transmit data at the same time. In this situation, when two stations associated with different ISPs attempt to transmit simultaneously, the protocol will detect the collision and initiate a process of collision resolution.

When two stations attempt to transmit at the same time, the protocol will detect the collision and each station will wait a random amount of time before attempting to retransmit the data. If a collision occurs again, the protocol will increase the amount of time each station must wait before attempting to retransmit. This process helps to ensure that only one station can transmit at a time.

When two stations, each associated with a different ISP, attempt to transmit at the same time, a collision is detected by the 802.11 protocol. The protocol then triggers a process of collision resolution, in which each station waits a random amount of time before attempting to retransmit the data. This process continues until only one station is transmitting, thus avoiding further collisions.

The solution is 256-248 = 8, 16, and 24. The broadcast address of the 16 subnet, where this host is located, is 23, and the range of acceptable hosts is 17–22.

This equals 254 after subtracting the 2 reserved addresses. You will therefore receive 254 valid hosts with the chosen subnet mask. The ability to assign 62 hosts an IP Address via a /24 subnet would be possible regardless of whether the IP Address is private or public. /16 would produce 65,534 hosts (or 124.125.0.1 - 124.125.1) as a result. This indicates that a "/16" leaves the final 16 bits (or final two integers) available for usage in specified addresses and a "/8" leaves the final 24 bits available for use.
