Drive mapping is commonly used in operating systems like Windows to establish a consistent and organized system for managing drives and their associated files and folders.

A SYN flood is a type of TCP/IP attack that randomly opens TCP ports. In this attack, the attacker sends a flood of SYN packets to the target server, but never completes the connection by sending the final ACK packet. This causes the server to keep waiting for the ACK packet and leaves the TCP ports open, eventually exhausting the server's resources and making it unable to handle legitimate requests. This attack can lead to denial of service (DoS) as the server becomes overwhelmed with half-open connections.

Non Parity is the correct answer because it is a type of memory error checking that does not check for errors in memory. Non Parity memory modules do not include any additional error checking mechanisms, such as parity bits, to detect and correct errors in memory. This means that if an error occurs in the memory, it will not be detected or corrected by the non parity error checking method.

The second step in the printing process is conditioning. Conditioning refers to the preparation of the printing surface before the ink is applied. This step involves treating the surface to remove any impurities or contaminants that may affect the quality of the print. Conditioning helps to ensure that the ink adheres properly to the surface and produces a clear and sharp image.

The speed of a laser and impact printer is typically measured in pages per minute (PPM). The range of 2-6PPM and 8-200PPM represents the possible speeds at which these printers can print documents.
