BIOS (Basic Input-Output System) is firmware that initializes a computer's hardware components upon startup, enabling proper communication between hardware and software. BIOS is responsible for detecting, testing, and initializing hardware components when the computer starts, allowing the operating system to take control of the computer.

eMMC is a standard that combines NAND flash memory and a controller into a single chip, reducing overall device manufacturing costs. It uses an 8-bit interface with one data channel, limiting read and write speeds. eMMC supports only one read or write operation at a time (half-duplex). Typical read and write speeds of eMMC range from 100-250 MB/s. eMMC chips are commonly used in mid-range and low-end mobile phones, tablets, and other similar applications (embedded systems). eMMC is mainly found in devices where higher performance is not a priority. The current eMMC standard is v. 5.1.

JEDEC, short for Joint Electron Device Engineering Council, is a nonprofit organization specializing in the development and maintenance of technical standards for the semiconductor industry. JEDEC was founded in 1958 and was originally part of the Electronic Industries Alliance (EIA). Today, JEDEC is an independent organization that includes more than 300 member companies from around the world.

JTAG je zkratka pro Join Test Action Group, tedy způsob standardizovaného testovacího přístupu k integrovaným obvodům definovaného normou IEEE 1149.1 z roku 1990. Není nikterak striktní, avšak určuje způsob, jakým mohou být testovací logické obvody zařazeny do integrovaných obvodů již osazených základních desek a testovat propojení mezi jednotlivými komponentami. JTAG komunikuje pomocí 5 pinů TDI, TDO, TCK, TMS, TRST (a GND).

LUKS is a disk encryption method primarily used in Linux and stands for Linux Unified Key Setup. It was created by Clemens Fruhwirth in 2004. LUKS is characterized by platform independence, making it usable in various tools and environments, which facilitates compatibility between different programs and ensures password management implementation in a documented and secure manner. LUKS uses dm-crypt as a backend for disk encryption, which has been part of the Linux kernel since version 2.6.

NAS je zkratka pro Network Attached Storage, volně přeloženo do češtiny síťové datové úložiště. Do NAS vkládáme jeden nebo více disků. S využitím více disků je možné sestavit diskové pole (RAID) a zvýšit tak zabezpečení ukládaných dat, případně zvětšit kapacitu. S NAS se nejčastěji setkáme v menších firmách a domácnostech a kromě funkce běžného souborového serveru obvykle disponuje řadou dalších funkcí, jako webový server, FTP, klient P2P sítí, různých multimediálních rozšíření atd.

Before 1984, memory types such as SRAM and DRAM existed. These were volatile memory types that could not retain their content without power, or only for a limited time. Dr. Fujio Masuoka set out to change this fact when he began researching and developing transistor memory for Toshiba sometime after 1970 (the exact date is unknown) that could store bits (data) without power. In 1984, Masuoka succeeded in his efforts by developing and introducing NOR flash memory to the production environment.

Parkovací rampy slouží pevnému disku (HDD) pro bezpečné zaparkování čtecích hlav po vypnutí disku. Jsou umístěny mimo oblast datových ploten. Tato metoda bezpečného umístění čtecích hlav mimo datové plotny se používá patrně u všech moderních pevných disků. Dříve některé disky měly čtecí hlavy zaparkované ve středu datových ploten, ale od této metody z více důvodů výrobci disků upustili.

Rooting an Android device means obtaining administrative (root) access to the Android operating system. By default, Android users have limited access to system folders and settings. Rooting allows users to gain full access to the entire system, enabling them to make modifications that would otherwise be impossible.
