Inter-Integrated Circuit
/aɪ tuː siː/
noun — "a simple two-wire bus for short-distance chip-to-chip communication."
HDMI
/eɪtʃ diː aɪ ɛm aɪ/
n. "Proprietary audio/video interface carrying TMDS streams with CEC unlike royalty-free DisplayPort."
DSC
/ˌdiː ɛs ˈsiː/
n. "VESA's visually lossless video compression enabling 8K@60Hz over DisplayPort HBR3 bandwidth limits."
DVI
/ˌdiː viː ˈaɪ/
n. "Digital video interface transmitting uncompressed TMDS pixel streams as DisplayPort's analog predecessor."
DisplayPort
/ˈdɪspleɪ pɔːrt/
n. "VESA's royalty-free digital audio/video interface transmitting uncompressed pixel streams over HBR/UHBR lanes."
Universal Serial Bus 4
/ˌjuː ɛs biː ˈfɔːr/
n. "Thunderbolt-derived USB-C protocol delivering 40-80Gbps tunneling for data/display/PCIe over single cable."
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:
AGP
/ˌeɪ-dʒiː-ˈpiː/
n. “The dedicated graphics highway of early PCs.”
AGP, short for Accelerated Graphics Port, is a high-speed point-to-point channel introduced in 1997 for connecting graphics cards to a computer’s motherboard. It was designed specifically to improve the performance of 3D graphics by providing a direct pathway between the GPU and system memory, bypassing the slower shared PCI bus.
Key characteristics of AGP include:
Peripheral Component Interconnect Express
/ˌpiː-siː-aɪ-iː/
n. “The high-speed lane that connects your computer’s components.”
PCIe, short for Peripheral Component Interconnect Express, is a high-speed interface standard used to connect expansion cards (such as graphics cards, NVMe SSDs, network cards) directly to a computer’s motherboard. It replaced older PCI and AGP standards by providing faster data transfer rates, lower latency, and scalable lanes for bandwidth-intensive components.
