If you've mistakenly typed "hFSC" instead of the correct term, here are a few possibilities you might have intended: "HFCS" is an abbreviation for High Fructose Corn Syrup, commonly used as a sweetener. "HFS" could refer to "Hindawi File System", a storage solution. Alternatively, "HFSC" might actually be what you intended, standing for "Hierarchical Fair Service Curve", a scheduling algorithm used in computer networks.
