The DisplayPort AUX channel is a half-duplex (bidirectional) data channel used for miscellaneous additional data beyond video and audio, such as EDID (I 2 C) or CEC commands. [8]: §2.4 This bidirectional data channel is required, since the video lane signals are unidirectional from source to display. AUX signals are transmitted across a ...
On 802.11 (Wi-Fi), channel bonding is used in Super G technology, referred to as 108 Mbit/s. It bonds two channels of standard 802.11g, which has 54 Mbit/s data signaling rate per channel. On IEEE 802.11n, a mode with a channel width of 40 MHz is specified. This is not channel bonding, but a single channel with double the older 20 MHz channel ...
Telecommunication is a compound noun of the Greek prefix tele-(τῆλε), meaning distant, far off, or afar, [7] and the Latin verb communicare, meaning to share. Its modern use is adapted from the French, [ 8 ] because its written use was recorded in 1904 by the French engineer and novelist Édouard Estaunié .
In this application the transmission channel is the CD itself. Cell phones also use coding techniques to correct for the fading and noise of high frequency radio transmission. Data modems, telephone transmissions, and the NASA Deep Space Network all employ channel coding techniques to get the bits through, for example the turbo code and LDPC codes.
The net bit rate of ISDN2 Basic Rate Interface (2 B-channels + 1 D-channel) of 64+64+16 = 144 kbit/s also refers to the payload data rates, while the D channel signalling rate is 16 kbit/s. The net bit rate of the Ethernet 100BASE-TX physical layer standard is 100 Mbit/s, while the gross bitrate is 125 Mbit/s, due to the 4B5B (four bit over ...
WEP used a 64-bit or 128-bit encryption key that must be manually entered on wireless access points and devices and does not change. TKIP employs a per-packet key, meaning that it dynamically generates a new 128-bit key for each packet and thus prevents the types of attacks that compromised WEP.
CCNA (Cisco Certified Network Associate) is an entry-level information technology (IT) certification offered by Cisco Systems.CCNA certification is widely recognized in the IT industry as the foundational step for careers in IT positions and networking roles.
A classic example is the cable news channel MSNBC, which overlaps with (and, in the case of very significant breaking news events, pre-empts) its network counterpart NBC News; in some cases, viewers may have trouble differentiating between the cable channel and either a counterpart network news organization or a local news operation, such as is ...
