a collision is when 2 different machines attempt to transmit onto the same wire at the same time.
then this happens, both computers abort the transmit, then wait a random time before re-attempting to transmit the data.

im not sure about the others.

I guess you can't read very well.. the link provided above mentions just about all of these:

frame = Shows the number of packets received incorrectly having a CRC error and a noninteger number of octets. On a LAN, this is usually the result of collisions or a malfunctioning Ethernet device.

collisions = Gives the number of messages retransmitted due to an Ethernet collision. This is usually the result of an overextended LAN (Ethernet or transceiver cable too long, more than two repeaters between stations, or too many cascaded multiport transceivers). A packet that collides is counted only once in output packets.

carrier = Not actually on that page but from what I know its the number of times the carrier is lost during a transmission.

Carrier, as-in the carrier wave that the data is transmited on.. in other words, the cable was un-pluged or the hub / switch turned off.

RX = received
TX = transmitted
