The Tent of the Tabernacle was divided into two(2) rooms (sections): The Holy of Hollies(kodesh-ha-Kadoshim) and The Holy Place(kodesh).
Here is the diagram that shows these rooms. Holy of Hollies room marked blue and Holy Place marked green.
The Holy Place room was the main room, where most of the services of the Tabernacle were performed and it housed three artefacts: The Table of Shewbread, The Menorah and the Altar of Incense.
The Holy of Hollies was the most sacred room of the Tent of the Tabernacle, and housed only one artefact - the Ark of The Covenant.
