Answer: Both A and B (DNS and TCP/IP)
Explanation: Internet supervisor protocols are the protocols that have the supervising standards for the internet functioning. DNS (Domain name system)is the system that supervises the internet by the function of the domain names that is accessed by the user.It acts like phone phone book that coverts the domain to the IP address.
TCP/IP is the(Transfer control protocol/Internet protocol) are the protocols that help in the function of the internet by providing the connection with the network.The internet runs with help of TCP/IP suite.Thus both, DNS and TCP/IP are supervisory protocol for internet.
The requirements are mainly written in a feature style notation, using some state charts,
context diagrams and other techniques to describe certain parts of the system. See, for
example, Software Requirements - Styles and Techniques [Lauesen00].
The functional requirements are divided into four sections. The three modules in figure 1
are developed by separate groups, each responsible for unit testing. All requirements for
the taxi, central and communication link component are written in a feature style notation.
In addition, a special part of the taxi component is the positioning system. This is dealt
with separately since there are special requirements present on this component.
The functional requirements consist of four sections: Taxi (3.1), Central (3.2), Communication
link (3.3) and Positioning system (3.4).
Answer:
C
Explanation:
Joe should backup all his data from his old mobile device to his PC and then import all the data to his new device via PC. This is the fastest way for transferring data than all the other options mentioned. Most of the time the devices with different OS cannot connect via Bluetooth so option B is not suitable here. If we talk about logging in to same email provider on the new device, it might work but it'll take a lot of time to transfer data to a new device since the data is been copied through internet. If Joe has a strong internet connection than it might be a suitable option for him but what if the connections breaks down in middle of transfer? Similarly NFC also uses internet connection, but that's not only the problem with NFC, like Bluetooth, NFC also works with similar OS devices. Apart from that NFC only transfers small payloads of data.
