Answer:
Bluetooth is a wireless communication is typically limited to six feet distances
Explanation:
Bluetooth is one type of communication maximum it covers 10 meters to 30 meters. but it is one to one communication made for data transactions. After 25 meters of coverage on communication will be very slow on data transactions. But Bluetooth has also had a limitation.
IR. It is one of communication where infrared technology used. It is like face to face communication and speed of data transaction limited and it is also one to one communication made for data transactions. Communication paired and covered very little distances.
NFC it is chip-based and covers very little in fact just to device meet each and communication started. And very it caries very little data during the data transactions. it is also one to one communication made for data transactions
RFID is one of communication and it is powerful to cover more areas with multiple connections at the same time. It has a limitation in distance and it covers like a net with a specific distance
Answer:
<u>How to implement a stack in C using an array?</u>
A stack is a linear data structure that follows the Last in, First out principle (i.e. the last added elements are removed first).
This abstract data type can be implemented in C in multiple ways. One such way is by using an array.
Pro of using an array:
No extra memory required to store the pointers.
Con of using an array:
The size of the stack is pre-set so it cannot increase or decrease.
Answer:
The correct answer to the following question will be "Encapsulation".
Explanation:
The wrapping of the data into a single unit or the method by which a header is applied to the data inherited from the above layer is termed as Encapsulation.
While relating to networking, encapsulation would be the method of storing and converting data through one protocol into another, so that the data can proceed over a network. A TCP/IP package contained under an ATM system, for example, is indeed a kind of encapsulation.
Therefore, Encapsulation is the right answer.
It can help ensure that everything is correct. Having an extra set of eyes can never hurt :)

Explanation:
A relation schema is the fundamental schema for a table. Which is In a relational kind of database (what individuals naturally refer to when they talk about database) each take can be referred to as a "relation" . therefore a relational schema is the design for the table.
