How to declare 2D array
Using Java as a programming language of reference, the syntax to declare a 2D array is:
Data-Type [][] Array-Name = new Data-Type[Rows][Column]
From the question, the data type is String. So, the syntax becomes
String [][] Array-Name = new String[Rows][Column]
Assume the array name is: myArray; The above becomes
String [][] myArray= new String[Rows][Column]
<em>I will not assume values for Rows and Column, but it is worth saying that Rows and Columns are positive integers greater than 1 to make the array a 2 D array</em>
Answer:
To avoid collision of transmitting frames.
Explanation:
CSMA/CA, carrier sense multiple access is a media access control protocol of wireless networks that allows for exclusive transmission of frames and avoidance of collision in the network. When a frame is not being sent, nodes listening for an idle channel gets their chance. It sends a request to send (RTS) message to the access point. If the request is granted, the access point sends a clear to send (CTS) message to the node, then the node can transmit its frame.
Many nodes on a wireless network are listening to transmit frames, when a frame is transmitting, the node has to wait for the access point to finish transmitting, so it sends a RTS message again to exclusively transmit a second frame.
