- project guardian — (project, security) A project which grew out of the ARPA support for Multics and the sale of Multics systems to the US Air Force. The USAF wanted a system that could be used to handle more than one security classification of data at a time. They contracted with Honeywell and MITRE Corporation to figure out how to do this. Project Guardian led to the creation of the Access Isolation Mechanism, the forerunner of the B2 labeling and star property support in Multics. The DoD Orange Book was influenced by the experience in building secure systems gained in Project Guardian.
- project planning — project management
- projection paper — sensitized paper for recording a projected image.
- projective plane — (mathematics) The space of equivalence classes of vectors under non-zero scalar multiplication. Elements are sets of the form {kv: k != 0, k scalar, v != O, v a vector} where O is the origin. v is a representative member of this equivalence class. The projective plane of a vector space is the collection of its 1-dimensional subspaces. The properties of the vector space induce a topology and notions of smoothness on the projective plane. A projective plane is in no meaningful sense a plane and would therefore be (but isn't) better described as a "projective space".

- refractive index — index of refraction.
- register dancing — Many older processor architectures suffer from a serious shortage of general-purpose registers. This is especially a problem for compiler-writers, because their generated code needs places to store temporaries for things like intermediate values in expression evaluation. Some designs with this problem, like the Intel 80x86, do have a handful of special-purpose registers that can be pressed into service, providing suitable care is taken to avoid unpleasant side effects on the state of the processor: while the special-purpose register is being used to hold an intermediate value, a delicate minuet is required in which the previous value of the register is saved and then restored just before the official function (and value) of the special-purpose register is again needed.
