What is the difference between a Fund and a Campaign in Sumac?

In Sumac, the Fund represents the purpose for a donation: how the donor wants you to use the money they've donated.
If you allow donors to specify that a donation is for a particular purpose (e.g. “here is $100 to use for your Day Program" or “here is $10,000 for your Capital Campaign”), then the purposes (e.g. Day Program and the Capital Campaign) are Funds. Sumac can record and report on  which donations have been allocated to which Funds, or which pledges relate to a which Funds.

A Campaign is a fundraising effort: a set of steps you pursue to get donations. For example, your Christmas Fundraising Drive might be a Campaign. Sumac can record which communications, donations, and pledges relate to a particular campaign.

Note: Capital Campaigns often have a set of steps you might pursue to get donations, and would also be the purpose for the donations you receive. It is common to see "Capital Campaign" as both a Campaign and a Fund in Sumac.
