Time Division Multiple Access
/ˌtiː diː ɛm ˈeɪ/
n. "Multiple access technique allocating time slots to users sharing single frequency channel unlike FDMA subcarriers."
WiFi
/ˈwaɪ faɪ/
n. "IEEE 802.11 WLAN standard using OFDM/CSMA-CA for infrastructure/IBSS connectivity unlike Bluetooth piconets."
Bluetooth
/ˈbluːtuːθ/
n. "Short-range wireless PAN standard using FHSS in 2.4GHz ISM band for piconet/scatternet device pairing."
UDMA
/ˈʌl-trə diː-ɛm-eɪ/
n. “An advanced version of Direct Memory Access (DMA) for faster data transfer between storage devices and system memory.”
Direct Memory Access
/diː-ɛm-eɪ/
n. “A method for transferring data between devices and memory without involving the CPU for each byte.”
DMA, short for Direct Memory Access, is a data transfer technique that allows peripheral devices, such as HDDs, SSDs, or network cards, to read from or write to system memory directly, bypassing the CPU for individual data moves. This reduces CPU overhead, allowing the processor to focus on other tasks while large blocks of data are transferred efficiently.
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.”
Congestion Window Reduced
/siː-dʌbəl-juː-ɑːr/
n. “A TCP header flag used to indicate that congestion has been acknowledged and the sender can resume normal transmission.”
Explicit Congestion Notification
/iː-siː-ɛn/
n. “A mechanism in TCP/IP networks for signaling congestion without dropping packets.”
ECN, short for Explicit Congestion Notification, is a feature of modern IP networks that allows routers and endpoints to signal network congestion to senders proactively. Instead of relying solely on packet loss to indicate congestion, ECN marks packets to alert the sender to slow down, improving network efficiency and reducing latency.
Explicit Congestion Notification Echo
/iː-siː-iː/
n. “A TCP header flag used to indicate Explicit Congestion Notification.”
In the context of the Transmission Control Protocol (TCP), ECE (short for ECN Echo) is a flag that signals the detection of network congestion without dropping packets. It works in conjunction with Explicit Congestion Notification (ECN) mechanisms to provide more efficient and controlled congestion management.
