The real question here is why do you want to know? Do you think you are missing something?
Tiger comes in 2 Power PC versions. A 4 CD Version and 1 DVD version however Jaguar 10.2 and under is single cd
Yikes, 10.1 is bad. Please if you can use 10.4
A Mac which can run 10.1, or came with 10.1 or earlier, will have doubtful performance under 10.4. It must be a G3 model judging from this so unless it's a PowerMac or the later Pismo model PowerBooks, its performance will be 'lacking.'
A processor with 500MHz+ and maxed out RAM is highly recommended for Tiger. Otherwise stick with Panther.
Also: 10.1 was a hell of a lot better than 10.0
To install? 1, just like every release before or since...
