(n.) Also referred to as TCP session hijacking, a security attack on a user session over a protected network. The most common method of session hijacking is called IP spoofing, when an attacker uses source-routed IP packets to insert commands into an active communication between two nodes on a network and disguising itself as one of the authenticated users. This type of attack is possible because authentication typically is only done at the start of a TCP session. Another type of session hijacking is known as a man-in-the-middle attack, where the attacker, using a sniffer, can observe the communication between devices and collect the data that is transmitted.

Used in 3-D computer graphics a shader is a small program or set of algorithms that determines how 3-D surface properties of objects are rendered, and how light interacts with the object within a 3-D computer program. Newer GPUs calculate shaders where previously it was an algorithm calculated by the CPU.
- shadow copy
In some Windows operating systems, when a system restore point is requested, a shadow copy of a file or folder is created. The shadow copy is essentially a previous version of the file or folder at a specific point. See System Restore.
