C. full featured
Explanation:
You need to make use of the full-featured version of the word processing programs to use the illustrations that are part of the program. And simple versions might not have that. By fully featured it means you need to have the license included or else you will be able to use it for a few days or a maximum of 3 months, and that is certainly not a good idea.
How efficient well if we are transmitting 6bits and we need 10 to transmit the 6 bits that would be 6/10 = .6 = 60% efficient.
The answer in this question is that once the Adaptor or router received the destination IP address (even if we entered in the incorrect MAC address) the router or adapter would remove the IP address from the Ethernet frame and using ARP, would get the correct MAC address of the destination.
Answer:
The "a" Option is correct.
Explanation:
The "COUNTIF" function counts every cell that, given a condition (value), suits into it. As you want to know the number of cells that contain a value of at least 50, the condition must be properly written to get the correct answer. Unless it is a cell value (e.g. B3), the condition must always be written with quotes (""). So, the options b and c are automatically discarded.
The d option appears to be correct, but it's not. If the condition is written ">50", the function will count every cell with a value above 50. But we're searching values at least (including) 50. So the correct answer is the a option.
