Crystal vs. TTL Clock ? What's the difference?

[Farce Milverk]

Hi,

What's the difference between a TTL Clock and a crystal?

I'm curious to know if I can substitute a TTL clock (1 MHz specifically) for
a crystal.
Thanks for any info.

It's been a while since I had a course on this but I think crystals are more
accurate.
