When a software program takes hundreds of man-hours to develop, it is understandable that the programmers do not want to just give it away. For example, in the terms of the Microsoft Office software license, you will find the following statement: “This software is licensed, not sold.

Cybersecurity is increasing in importance with the growing number of tools and technology at the hands of those attempting to infiltrate systems, steal data, and hold systems for ransom. Strong passwords - Good options to consider would be: a minimum length of at least 10 characters, require the use of special characters or upper and lowercase letters.

At the end of its boot sequence, the kernel tries to determine the format of the image from its first few blocks of data, which can lead either to the initrd or initramfs scheme.

The following diagram modifies the above example by moving two bits from the host part to the network prefix to form four smaller subnets, each one quarter of the previous size.
