The answer is "hexadecimal": the notation representing numbers using the sixteen symbols 0–9 and A–F.

The answer is "complement": the number used to handle subtraction as addition or to represent negative numbers.

The answer is "XOR": the logical operation that is true only when the two inputs differ.

The answer is "standard deviation": the measure of how widely data is spread around the mean.

The answer is "correlation coefficient": the value expressing the strength of the linear relationship between two variables from −1 to 1.

The answer is "stack": the LIFO data structure that takes out the item stored most recently first.

The answer is "queue": the FIFO data structure that takes out the item stored first first.

The answer is "hash table": the data structure searching quickly using a storage position computed from a key.

The answer is "tree structure": nodes linked hierarchically in parent-child relationships from a single root.

The answer is "quicksort": recursively picking a pivot and splitting the data into larger and smaller parts.

The answer is "clock frequency": the number of times per second of the signal by which a CPU times its operation.

The answer is "GPU": the processor that excels at image processing and at running many calculations of the same kind in parallel.

The answer is "interrupt": suspending the processing under way to deal with an event that takes priority.

The answer is "DMA": transferring data between an I/O device and main memory without going through the CPU.

The answer is "RAID 5": distributing data and parity across several drives and tolerating the failure of one.

The answer is "NAS": the storage device connecting directly to a network to provide file sharing.

The answer is "thin client": limiting the functions on the client device and performing processing and data management mainly on the server.

The answer is "lossless compression": the method that restores the original data exactly when decompressed.

The answer is "sampling": measuring an analog signal at regular intervals to turn it into discrete values.

The answer is "resolution": the measure expressing the fineness of an image by the density or total number of its pixels.

The answer is "MAC address": the physical address identifying the network interface of a device on a LAN.

The answer is "switching hub": the device forwarding a frame to the port corresponding to the destination MAC address.
