A slot (just like an epoch) is simply a unit of time on Solana.

A slot can then either contain a block or not (skipped slot). A slot refers to the period of time in which a slot leader produces ledger entries. The period of time for which each leader ingests transactions and produces a block.

There's the concept of a leader in Solana. A leader for a particular period is the only validator that is allowed to produce a block.

Solana has a system that changes the leader frequently. The window of opportunity a leader has to produce a block before that privilege is re-assigned to a different validator is called a slot.
