AE Title
Application Entity Title
An AE Title is the name a DICOM device identifies itself by on the network, used together with its IP address and port to address it when another device opens an association.
What AE Title means in practice
It is a short string, up to sixteen characters, and it is case-sensitive — which is the single most common cause of a DICOM connection that refuses to establish despite correct addressing. Both ends usually need configuring: the sender needs the receiver's AE Title, and a receiver often restricts which calling AE Titles it will accept.

This definition follows NEMA PS3.8 Annex C.1 — Application Entity Title naming, published by NEMA as part of the DICOM standard.

Storage SCP
A Storage SCP is the role a device plays when it accepts incoming DICOM images, listening for C-STORE requests and storing what it receives — the role a PACS or an archiving viewer performs.
Storage SCU
A Storage SCU is the role a device plays when it initiates a C-STORE request to send DICOM images to a Storage SCP — the role a CT or MR console performs when it pushes a finished study to a PACS.
C-ECHO (DICOM Verification)
C-ECHO is the DICOM network service that tests whether two devices can communicate, without transferring any image data — the equivalent of a ping at the DICOM layer.
C-STORE
C-STORE is the DICOM network service used to transfer a composite object — an image or similar instance — from one device to another, and it is the operation behind "sending a study" to a PACS.
