A zettabyte describes a unit of data or information that is equal to 1,000,000,000,000,000,000,000 bytes. The term is equal to a billion terabytes and the symbol ZB represents it. Zebibyte (ZiB) describes a measurement of data using the power of 1024. A single zettabyte is equivalent to 1,024 exabytes and is used prior to the …
Windows NT, Me, and Windows XP’s Pre Service Pack 2 users sometimes experience the “Error Performing In-page Operation” error when attempting to copy files from a disk.

SIMD (Single Instruction Multiple Data) is a computer science method of combining multiple operations into a single computer instruction. The total number of operations combined is normally a factor of the power of two. The employment of SIMD results in significant savings in speed for algorithms designed to work in parallel. The technology is used …
Wardriving is the physical act of seeking out a WiFi network with a mobile device or laptop while driving a vehicle.

Luminous flux (luminous power) is the measurement of the (perceived) power of light. It is adjusted to take the human eye’s sensitivity to the different wavelengths of light into account. Luminous flux differs from radiant flux in this manner, since radiant flux is a measurement of the total power of light emitted independent of wavelength. …
Molality is the number of moles in a solute per kilogram of solvent. It is often confused with the term molarity, which is an alternative unit for concentration that measures the number of moles of solute per liter of solution. Molality is commonly used when experiments require significant temperature changes. This is because a solute’s …
Cutoff frequency (corner or break frequency) is commonly used in the physics and electrical engineering fields. This frequency causes a device to stop operating in an efficient manner, resulting in it shutting down or being cut off. More technically, the cutoff frequency reduces energy flow through the device and prevents it from working as designed. …
