A floor joist is one of the boards that runs under your subfloor, from sill plate to sill plate. They are usually supported in the center of the home by the main beam (more on that in the next section). If you have damaged floor joists, you will normally have dips in your floor, or high and low spots.

A sill plate or mudsill is the bottom horizontal member of a floor system to which vertical members (floor joists) are attached. Sill plates are usually composed of lumber in sizes of 2″×4″, 2″×6″, 2″×8″, and 2″×10″. In modern construction, the sill plate is made of treated lumber and is anchored to the foundation wall.
It is located above the cinder block or concrete foundation wall and creates the outer box of the floor assembly. The rim joist sits directly on top of the sill plate. Unfortunately, rim joists are not typically built with pressure treated wood so they can grow mold and fungus when they become damp. What is the Sill Plate?
It does look like the floor joist is cracking right where a nail or lag screw is going into the floor joist which seems to indicate that the ledger board is not supporting the floor joist properly. Since the joist in the picture looks like it has pulled away a little more than half the thickness of the ledger board, it seems prudent to pull it back so the joist has more area to sit on the ...
Rim joists are set onto the top plate (on upper-level walls) or the sill plate (on foundation walls) and are nailed into the plate with framing nails. This connection may be reinforced with pieces of metal strapping (called tie-downs) to prevent a separation of the floor due to forces of high wind or seismic activity.
The band joist and sill plate are the set of boards (in wood frame houses), or blocks (in a brick house) that sit on top of the foundation wall and run in a band around the house. Great video explaing band / sill and why you need to air seal this area.

The first floor has 2"x7.75" floor joists that are connected directly to the sill plate which is a wood block 5.75"W x 7.75"H. The wood block sits on top of a 8" CMU foundation wall.

Another box sill that is claimed to be strong, warm, and "rat-proof" is shown in Fig. 8. First there is a wall-plate or bed-plate, say of 2 by 8 inches, and an upright the same width as joist, thus allowing the studding to rest on the
Higher floors use something called a "top plate" instead of a sill plate that forms the outside structure for flooring joists on that level. Next in line are the rim joists, which attach on end to the sill or top plate with framing nails, forming a border around the entire foundation and upper frame of the house.
