PIO
/piː-aɪ-oʊ/
n. “A method for transferring data between the CPU and a storage device using programmed instructions rather than direct memory access.”
Advanced Technology Attachment
/ˈeɪ-tiː-eɪ/
n. “A standard interface for connecting storage devices such as hard drives and optical drives to a computer.”
ATA, short for Advanced Technology Attachment, is a standard interface used for connecting storage devices like HDDs and optical drives to a computer’s motherboard. ATA defines the electrical, physical, and logical specifications for data transfer between the storage device and the CPU.
Over time, ATA has evolved into different versions:
PATA
/ˈpæ-tə/ or /ˈpɑː-tə/
n. “An older parallel interface standard for connecting storage devices to a computer’s motherboard.”
PATA, short for Parallel Advanced Technology Attachment, is a legacy interface used to connect storage devices such as HDDs and optical drives to a motherboard. It uses parallel signaling with a wide ribbon cable (typically 40 or 80 wires) to transfer data between the device and the system.
SATA
/ˈsɑːtə/ or /ˈsætə/
n. “A computer bus interface that connects storage devices like hard drives and SSDs to a motherboard.”
SATA, short for Serial Advanced Technology Attachment, is a high-speed interface standard used to connect storage devices such as HDDs, SSDs, and optical drives to a computer’s motherboard. SATA replaced the older parallel ATA (PATA) standard, providing faster data transfer, thinner cables, and improved efficiency.
VRAM
/ˈviː-ræm/
n. “Video Random Access Memory used by GPUs to store image and graphics data.”
VRAM is a type of memory dedicated to storing graphical data that a GPU needs to render images, textures, and frame buffers efficiently. It provides high bandwidth and fast access, allowing the GPU to process large volumes of visual data without relying on slower system RAM.
Digital Signal Processor
/diː-ɛs-piː/
n. “A specialized microprocessor designed to efficiently perform digital signal processing tasks.”
DSP, short for Digital Signal Processor, is a type of processor optimized for real-time numerical computations on signals such as audio, video, communications, and sensor data. Unlike general-purpose CPUs, DSPs include specialized hardware features like multiply-accumulate units, circular buffers, and hardware loops to accelerate mathematical operations commonly used in signal processing algorithms.
NVIDIA
/ɛnˈvɪdiə/
n. “An American technology company specializing in GPUs and AI computing platforms.”
NVIDIA is a leading technology company known primarily for designing graphics processing units (GPUs) for gaming, professional visualization, and data centers. Founded in 1993, NVIDIA has expanded its focus to include high-performance computing, artificial intelligence, deep learning, and autonomous vehicle technologies.
iGPU
/ˈaɪ-dʒiː-piː-juː/
n. “A graphics processor built directly into the CPU or system-on-chip.”
iGPU, short for integrated Graphics Processing Unit, refers to a graphics processor that is embedded within a CPU or system-on-chip rather than existing as a separate, dedicated graphics card. Unlike discrete GPUs, an iGPU shares system resources such as memory and power with the CPU.
NVMe
/ˌɛn-viː-ˈɛm-iː/
n. “The high-speed protocol that lets SSDs talk directly to the CPU.”
NVMe, short for Non-Volatile Memory Express, is a storage protocol designed to maximize the performance of modern SSD drives by connecting directly to the CPU over PCIe lanes. Unlike older protocols like SATA, NVMe eliminates legacy bottlenecks and leverages the low latency and parallelism of NAND flash memory to achieve extremely fast read/write speeds.
Key characteristics of NVMe include:
PCI
/ˌpiː-siː-ˈaɪ/
n. “The standard expansion bus that connected peripherals before PCIe.”
PCI, short for Peripheral Component Interconnect, is a local computer bus standard introduced in the early 1990s that allowed expansion cards, such as network adapters, sound cards, and graphics cards, to connect directly to a computer’s motherboard. It provided a shared parallel interface for data transfer between the CPU and peripheral devices.
Key characteristics of PCI include:
