the 'appropriate' tool for a particular job.

ARP Cache - Answer✔✔-ARP (address resolution protocol) is a protocol used on local networks

to map IP addresses to MAC addresses. When a computer receives an ARP response, it saves it

into the ARP cache.

ARP Spoofing / Poisoning - Answer✔✔-The flaw in the ARP protocol comes because, if an ARP

response is sent to a computer, it will store that value in its ARP cache even if it didn't make an

ARP request asking for a response.

Arrays - Answer✔✔-In C, you have to specify the type of the array when you create it, and it can

only ever hold that type of data. You can't mix and match within the same array.

make long SQL statements more readable, more descriptive or set the table headings for a

binary to characters. Originally 7 bits wide for up 127 characters. Now is 8 bits wide and up to
