Ethical hacking involves an authorized attempt to gain unauthorized access to a computer system, application, or data. Carrying out an ethical hack involves duplicating strategies and actions of malicious attackers. This practice helps to identify security vulnerabilities which can then be resolved before a malicious attacker has the opportunity to exploit them.

Computer networks and internet protocols are essential components of today's technology-driven world. They allow devices to connect and communicate with one another, enabling the sharing of information and resources. Multiple choice questions MCQs on this topic test a student's understanding of the various concepts and protocols involved in computer networks and internet communication. This is the most common port number used for web traffic and is the default port for HTTP connections. In AIMD, the sending rate is increased linearly when there is no congestion and decreased multiplicatively when congestion is detected. This increase in the sending rate is intended to make efficient use of the available network capacity. The AIMD algorithm has been widely used in various network protocols such as TCP to achieve congestion control and prevent network congestion. The minimum TCP header size is 20 bytes bits which includes the mandatory fields such as the source and destination port numbers, sequence number, acknowledgement number, and control flags. The header size can increase up to 60 bytes bits if optional fields such as window size, urgent pointer, and options are included.
