- occupational guidance — advice and guidance relating to employment issues and career choices
- one-way hash function — (algorithm) (Or "message digest function") A one-way function which takes a variable-length message and produces a fixed-length hash. Given the hash it is computationally infeasible to find a message with that hash; in fact one can't determine any usable information about a message with that hash, not even a single bit. For some one-way hash functions it's also computationally impossible to determine two messages which produce the same hash. A one-way hash function can be private or public, just like an encryption function. MD5, SHA and Snefru are examples of public one-way hash functions. A public one-way hash function can be used to speed up a public-key digital signature system. Rather than sign a long message, which can take a long time, compute the one-way hash of the message, and sign the hash.
- overcurrent detection — Overcurrent detection is a method of establishing that the value of current in a circuit exceeds a particular value for a particular length of time.
- packed encoding rules — (protocol, standard) (PER) ASN.1 encoding rules for producing a compact transfer syntax for data structures described in ASN.1, defined in 1994. PER provides a much more compact encoding then BER. It tries to represents the data units using the minimum number of bits. The compactness requires that the decoder knows the complete abstract syntax of the data structure to be decoded, however. Documents: ITU-T X.691, ISO 8825-2.

- point of articulation — place of articulation.

- production department — the department of a business or organization responsible for manufacturing products
- progressive education — any of various reformist educational philosophies and methodologies since the late 1800s, applied especially to elementary schools, that reject the rote recitation and strict discipline of traditional, single-classroom teaching, favoring instead more stimulation of the individual pupil as well as group discussion, more informality in the classroom, a broader curriculum, and use of laboratories, gymnasiums, kitchens, etc., in the school.
