Arap V Bootp

[zillah]

From cisco curriculum :

" The bootstrap protocol (BOOTP) operates in a client-server environment, and only requires a single packet exchange to obtain IP information.

However, unlike RARP, BOOTP packets can include the IP address, as well as the address of a router, the address of a server, and vendor-specific information ".

1- Does RARP not operate in client-server environment?

2- Does ARAP require more than one packet?

3- what does this mean : "However, unlike RARP, BOOTP packets can include the IP address, as well as the address of a router, the address of a server, and vendor-specific information".
