The answer is C. Central processing unit (or CPU).
The trick is in the name, central processing unit :)
When the network stack translates an IP address (network address) to a MAC address (data link address) it sends a broadcast using ARP to all devices on the subnet asking who has the specified IP address. The device with that IP address will then respond with it's MAC address to the ARP message's source.
With this in mind the answer to your question would either be broadcast or ARP request depending on what you have been learning in class.
Answer:
SQL pattern matching allows you to search for patterns in data if you don't know the exact word or phrase you are seeking. This kind of SQL query uses wildcard characters to match a pattern, rather than specifying it exactly. For example, you can use the wildcard "C%" to match any string beginning with a capital C.
Explanation:
Answer: Transmission rate
Explanation:
Transmission rate is measured in bits per second and it transmitted the data at the different rate across the circuit. The speed in which the data rate is transferred from one device to anther is known as transmission rate.
The transmission rate are always less as compared to signalling rate because the signalling rate contain the total data which basically include the overhead to control the information.
Therefore, transmission rate is the correct option.
