| FAIR | FAIR Data Principles | Data should be Findable, Accessible, Interoperable, and Reusable. | Data | So your results don't die with you. | |
| FAIRsharing | Platform for finding data standards and policies | Shows which standards and policies are used in scientific disciplines. | Data | So you don't reinvent the wheel. But sometimes you want to, right? | |
| FHRP | First-Hop Redundancy Protocol | A protocol that makes a router fault-tolerant. | Network & Infrastructure | If the primary router fails, the backup takes over. | |
| FIFO | First In, First Out | A queue where the first in is the first out. | Development | Like a queue at the store, but for CPU tasks. | |
| FP | Functional Programming | A paradigm where functions are values. | Development | Like in mathematics, but with code. | |
| FPGA | Field-Programmable Gate Array | A chip that can be reprogrammed for a specific task. | General | Like a construction set for hardware. | |
| FTP | File Transfer Protocol | A good old file transfer protocol. | Network & Infrastructure | Still alive, but being replaced by SFTP. | |
