Answer:
Preamble
Explanation:
In the computer network , the ether-net is the frame of link layer protocol data. This frame is used ether net with physical layer of transport mechanism. The ether net frame is of different type.
- The ether-net II
- The Novel raw IEEE 802.3
- IEEE 802.2 LLC
- IEEE 802.2 SNAP
Each of the Ethernet frame started from Ether net header. It contains the source and the destination. The MAC address is called its first two address.

Please see below
Explanation:
Yes, there indeed is ethical justification for hacking certain computer systems. Since computer scientists are required to keep the system secure from external threats, so they make use of it when testing the network for potential loopholes that could make it vulnerable. It is beneficial in that it can help manifest the weaknesses present in the system, which can then be corrected for.
Answer:
#include <stdio.h>
int hexToDec(const int hexNum[]){

Answer:
<u>Conditional</u> formatting is automatically updated if you change data in the worksheet.
Explanation:
Conditional formatting can be described as a tool that allows users to format a particular cell or a group of cells. The formatting also changes for any data being changed in the sheet.
A particular cell can have up to three format conditions and these conditions will be applied automatically to any changes entered in the cell. The conditional formatting also has the option to highlight the important cells.
