Encryption
A security method that applies a specific algorithm to data in order to alter the data appearance and prevent other
devices from reading the information.
Firmware
Program that is inserted into programmable read-only memory (programmable read-only memory), thus becoming a
permanent part of a computing device.
Fragmentation Threshold Value
Indicates how much of the network resources is devoted to recovering packet errors. The value should remain at its
default setting of 2,432. If you experience high packet error rates, you can decrease this value but it will likely decrease
overall network performance. Only minor modifications of this value are recommended.
Fragmentation
