Answer:
The office computer is part of a network.
The server responds with a packet when a request packet is sent by a client.
The computer confirms the IP address and port number to retrieve the encapsulated data, for a specific application in the system.
Explanation:
The computer network is the communication of two or more devices. There are two forms of network, there are peer to peer and client/server networks.
The peer to peer network allows for each computer to send and receive data, while the client/server network have a dedicated server to send resources to clients that request for it. Data transferred are encapsulated in the network, transport and data-link layer PDU headers and would be decided in the destination system to retrieve the data.
The answer is a FRAME.
This is part of data encapsulation process. The data link layer encapsulates a packet into a frame. The
Frame’s header carries hardware address of the source and destination hosts. A
frame includes the network layer header, transport layer header and all upper
layer information.

Digital forensics comes under forensic science, which is mainly used to investigate and search for evidence of crime through electronic devices i.e. computer systems.
Digital forensics specialists are mainly used to deal with the cases related to electronic devices i.e. computers, to search for evidence of the case, which helps to make the correct decision.
Answer:
C. Wait for about 30 minutes for the system to cool downand try again.
Explanation:
In computer system troubleshooting, there are two areas where problems can arise. They are hardware and software related issues.
software issues are application related like an application not installed properly, malicious software attack, corrupted operating system etc, while hardware has to do with a faulty hardware component in the system.
Example of a hardware related issue, when the active fan is faulty, the computer overheat and eventually shuts down to cool the system. When it cools down, the computer can boot again.
To confirm that the fan is faulty, when it shuts down to cool, wait for some time and try booting the system again. If it comes on, then the fan is bad.
