Statement two and three is correct.
Statement 1 is incorrect. A relative reference changes when a formula is copied to another cell while Absolute references remain constant. However, it is safe to say that an absolute address can be preceded by a $ sign before both the row and the column values. It is designated by the addition of a dollar sign either before the column reference, the row reference, or both. Statement C is also correct. A mixed reference is a combination of relative and absolute reference and the formula (= A1 + $B$2) is an example of a mixed cell reference.
Answer:
There could be a collision if a hidden node problem occurs.
Explanation:
CSMA/CA(carrier sense multiple access/ collision avoidance) is a multiple access method in wireless networking, that allows multiple node to transmit. Collision avoidance of this method is based on preventing signal loss or downtime as a result of collision of transmitting multi signals.
If a node at step 4(transmit frame) sends the first frame, the node still needs to send a RTS(request to send) and to receive a Clear to send (CTS) from the WAP, the is to mitigate the issue of hidden node problem as all frame are treated as unit, so other listening nodes, not detected would seek to connect and transmit as well.

Answer:
API keys
Explanation:
API (Application Programming Interface) is a computing interface that defines the interaction between multiple software intermediaries.
API key is a specific identifier use authenticate the developer user and call programs for the API.
The API keys often serve as a specific identifier and a secret token for authentication, and usually have a set of access rights to the API associated with it.
These are commonly used to authenticate a project with an API instead of a human user. Different platforms can execute and use API keys in different ways.
Answer:
See the explanation
Explanation:
Initialize a string called str and a boolean called found
Initializes a for loop that iterates through the str
Inside the for loop:
Gets the characters of the str and assigns them to the ch. Checks if the character is an uppercase or not. If an uppercase character found, updates the found as true and stops the loop.
For this example, the loop will stop when the character "E" is reached
