Answer:
PrintWriter variable = new PrintWriter("output.txt");
Explanation:
There are two ways of declaring a reference variable in programming.
One way is
Reference Variable-name = new Reference ("some texts here");
While the other is
Reference Variable-name;
Variable-name = new Reference ("some texts here");
Both ways are valid ways of reference variable declaration.
In the question above, the reference is PrintWriter, it points to output.txt and the question says "write a single statement";
Hence, we make use of
PrintWriter variable = new PrintWriter("output.txt");
A reference variable is declared to be of a specific type and that type can never be changed.
Answer:
If two network adapters on the same network transmit at the same time, one of the adapters would stop transmitting until the second adapter has finished transmitting before retransmission
Explanation:
Carrier Sense Multiple Access with Collision Detection (CSMA/CD) is a network protocol used to prevent data collision. CSMA/CD detects collisions by sensing transmissions from other nodes. If a collision is detected, the node stops transmitting, sends a jam signal, and then waits for some time until the channel is idle before retransmission.
If two nodes on the network start transmitting at the same time, the nodes will detect the collision and take the appropriate action.
If two network adapters on the same network transmit at the same time, one of the adapters would stop transmitting until the second adapter has finished transmitting before retransmission

Answer:
The user's account is blocked due to several unsuccessful login attempts.
Explanation:
Any device having a password security has a property of blocking the account or device in use after noticing several unsuccessful attempts of login.
So as a precautionary measure when the software notices such activity it blocks the access to that account so that any intruder might not be able to enter the account premises.
Same is the case with the employee who was trying to access his own account but due the expired password he made several attempts but couldn't log in. The software took it as an intruder and blocked the account.
The employee after requesting for password reset again tried to login but the account was blocked so he could not be able to access it again.
