Module

/siː ɛs ɛs ɡrɪd/

noun — “the master puppeteer for laying out web content in neat rows and columns.”

CSS Grid, short for Cascading Style Sheets Grid Layout, is a powerful layout system in CSS that enables developers to create two-dimensional grid-based designs for web pages. Unlike CSS Flexbox, which is mostly one-dimensional (row or column), CSS Grid allows both rows and columns to be defined simultaneously, providing precise control over placement, alignment, and spacing of elements within a container.

/siː ɛs ɛs ˈflɛks.bɒks/

noun — “the stretchy superhero layout tool that makes elements align themselves perfectly.”

CSS Flexbox, short for Cascading Style Sheets Flexible Box Layout, is a modern layout module in CSS that provides an efficient way to arrange and distribute space among items in a container, even when their size is unknown or dynamic. Unlike traditional box layouts, Flexbox simplifies alignment, spacing, and ordering, making responsive and flexible designs much easier to implement.

/ˈhɑːrd.wɛər sɪˈkjʊr.ɪ.ti ˈmɒd.juːl/

noun — "because sometimes your keys need a safe stronger than your office door."

/ˈɛsˌræm/

noun … “High-speed, volatile memory with no refresh needed.”

/ræm/

noun … “Fast, temporary memory for active data.”

/nɒn ˈvɑːlətɪl ˈmɛməri/

noun … “Memory that retains data without power.”

Non-Volatile Memory (NVM) is a type of memory that preserves stored information even when the system loses power. Unlike volatile memory such as RAM, which requires constant power to maintain data, non-volatile memory maintains content permanently or until explicitly overwritten. This property makes NVM essential for storage devices, firmware, and persistent configuration in embedded systems.

/ˈbuːtˌloʊdər/

noun … “Initial program that starts the system.”

Bootloader is a small, specialized program stored in non-volatile memory such as ROM or Flash, responsible for initializing hardware components and loading the operating system or runtime environment into RAM. It serves as the first stage of the boot process, bridging the gap between firmware and the OS, ensuring that the system starts reliably and securely.

/iˌiːˌpɹoʊˈm/

noun … “Electrically erasable programmable memory.”

/ˈfɜːrmwɛr/

noun … “Software embedded in hardware.”

Firmware is specialized software stored in non-volatile memory, such as ROM or Flash, that provides low-level control for a device’s hardware. It acts as an intermediary between the hardware and higher-level software, enabling the system to initialize, configure, and operate correctly. Firmware is essential in embedded systems, computers, networking devices, and peripherals.

/flæʃ/

noun … “Non-volatile memory with electrical erase and write.”

Flash is a type of non-volatile memory that can be electrically erased and reprogrammed. Unlike traditional ROM, Flash supports multiple write and erase cycles, making it suitable for storage devices like SSDs, USB drives, and embedded systems. It combines the speed of semiconductor memory with persistent data retention, bridging the gap between volatile RAM and slower mechanical storage.
