What is a disk array? A disk array, also called astorage array, is a data storage system used for block-based storage, file-based storage or object storage. The term is used to describe dedicated storage hardware that contains spinning hard disk drives (HDDs) or solid-state drives (SSDs)...
A bit is represented by a lowercase b. While a byte can hold a letter or symbol, a bit is the smallest unit of storage, storing just onebinarydigit. The standard number of bits in a byte is eight, but that number can vary from system to system, depending on the hardware. Fred Brook...
What is Mbps (megabits per second)? While looking for an internet provider, you’ve probably come across the term “megabits per second”, or Mbps. This is a unit of measurement used to evaluate internet connection speed. In this article, we’ll go over what this unit of measurement means...

VGA stands for Video Graphics Array. At its core, VGA is an analog interface standard for computer video output. It defines both a display hardware specification and a 15-pin connector type used to connect video sources (like computers) to display devices (like monitors). ...
array is controlled with a device called a shutter. This is a physical device that opens the lens to collect photons or closes it to prevent any coming in. The shutter can be either mechanical or electrical. In either case, it allows the bucket to collect photos for a short period in ...
What is a field programmable gate array (FPGA)? High-performance GPUs are well suited for deep learning or AI applications because they can handle a large volume of calculations in multiple cores with large amounts of available memory. Field programmable gate arrays (FPGAs) are versatile types ...
Talking about RAID metadata is a bit wrong, as they apply to every disk in the array. In this way, metadata accesses the disk to convert the physical block. In other words, these are the structures on the disk for marking up the array, to indicate its type, size, an order of disks...
