- halt and catch fire — (humour, processor) (HCF) Any of several undocumented and semi-mythical machine instructions with destructive side-effects, supposedly included for test purposes on several well-known architectures going as far back as the IBM 360.

- horizontal encoding — (processor) An instruction set where each field (a bit or group of bits) in an instruction word controls some functional unit or gate directly, as opposed to vertical encoding where instruction fields are decoded (by hard-wired logic or microcode) to produce the control signals. Horizontal encoding allows all possible combinations of control signals (and therefore operations) to be expressed as instructions whereas vertical encoding uses a shorter instruction word but can only encode those combinations of operations built into the decoding logic. An instruction set may use a mixture of horizontal and vertical encoding within each instruction. Because an architecture using horizontal encoding typically requires more instruction word bits it is sometimes known as a very long instruction word (VLIW) architecture.

- internet relay chat — (chat, messaging) (IRC) /I-R-C/, occasionally /*rk/ A client-server chat system of large (often worldwide) networks. IRC is structured as networks of Internet servers, each accepting connections from client programs, one per user.

Some Usenet jargon has been adopted on IRC, as have some conventions such as emoticons. There is also a vigorous native jargon (see the entry for "chat"). The largest and first IRC network is EFNet, with a smaller breakaway network called the Undernet having existed since 1992, and dozens of other networks having appeared (and sometimes disappeared) since.
