Connection: Used to make a connection between your app and an external data source, ie, sql server Command: Used to build queries, including user-specific parameters, to access records from a data source Recordset: Used to access records returned from an SQL query. With a recordset, you can navigate returned records. You can also add, modify or delete records.
Early binding allows developers to interact with the object’s properties and methods during coding permits the compiler to check your code. Errors are caught at compile time. Early binding also results in faster code Eg : Dim ex as new Excel.Application Late binding on the other hand permits defining generic objects which may be bound to different objectsyou could declare myControl as Control without knowing which control you will encounter. You could then query the Controls collection and determine which control you are working on using the TypeOf method and branch to the section of your code that provides for that type Eg : Dim ex as Object set ex =CreateObject(“Excel.Application”)

Forward Only: Fastest, can only move forward in recordset. Static: Can move to any record in the recordset. Data is static and never changes.

An in-process component is implemented as a DLL called ActiveX DLL, and runs in the same process space as its client app, enabling the most efficient communication between client and component. Each client app that uses the component starts a new instance of it. An out of process component is implemented as an EXE called ActiveX EXE, and unlike a dll, runs in its own process space. As a result, exe’s are slower then dll’s because communications between client and component must be marshalled across process boundaries. A single instance of an out of process component can service many clients.
