The Waterfall model is called the linear sequential model because the project flows in one direction through requirement analysis, design, coding, testing, deployment and maintenance, with each phase completed and signed off before the next begins and no overlap between them.

NFC is built on the high frequency band of radio frequency identification and uses magnetic induction between two loop antennas at 13.56 MHz, which is why the devices must be brought within about four centimetres of each other.

In the numeric form of chmod each of the three digits stands for one set of users, in the order owner, group and others, and each digit is the sum of read as 4, write as 2 and execute as 1.
