The unit of channel transmission rate in data communication is bps. What does it represent?
The unit of channel transmission rate in data communication is bps, which means "bits/second" or "bits/second". That is, the data transmission rate is numerically equal to the number of binary bits that constitute the data code transmitted per second. , also called "bitrate". The bit rate represents the number of bits transmitted per unit time and is used to measure the transmission speed of digital information; based on the number of bits occupied by each frame of image storage and the transmission bit rate, the speed of digital image information transmission can be calculated.
The operating environment of this tutorial: Windows 7 system, Dell G3 computer.
The channel transmission rate unit in data communication is bps, which means "bits/second", "bits/second", and generally refers to the bit rate.
Bit rate refers to the number of bits transmitted per second. The unit is bps (bit per second), which can also be expressed as b/s. The higher the bit rate, the greater the amount of data (number of bits) transmitted per unit time. Information in computers is represented by binary 0s and 1s, where each 0 or 1 is called a bit, represented by a lowercase b, which is a bit. Capital B means byte, 1 byte = 8 bits, that is, 1B = 8b. Indicates the size unit of the file. Generally, kilobytes (KB) are used to express the size of the file.
Bit rate is also called "binary bit rate", commonly known as "code rate". Indicates the number of bits transmitted per unit time. Used to measure the transmission speed of digital information, often written as bit/sec. According to the number of bits occupied by each frame of image storage and the transmission bit rate, the speed of digital image information transmission can be calculated.
In modern digital communications, the transmission volume of digital sound, video and other information is large, so it is often measured in kilobits per second or megabits per second, respectively written as kbit/sec (or kbps ) and Mbit/sec (or Mbps). For example, the information amount of a digitized high-quality sound signal without compression encoding is generally 768kbit/sec, while the information amount of an ordinary color TV signal after digitization can reach 216Mbit/sec. A good digital transmission channel can transmit dozens of color TV programs, and its capacity can reach several gigabits or gigabits per second (written as Gbit/sec or Gbps).

Use ddrescue to recover data on Linux
Mar 20, 2024 pm 01:37 PM
DDREASE is a tool for recovering data from file or block devices such as hard drives, SSDs, RAM disks, CDs, DVDs and USB storage devices. It copies data from one block device to another, leaving corrupted data blocks behind and moving only good data blocks. ddreasue is a powerful recovery tool that is fully automated as it does not require any interference during recovery operations. Additionally, thanks to the ddasue map file, it can be stopped and resumed at any time. Other key features of DDREASE are as follows: It does not overwrite recovered data but fills the gaps in case of iterative recovery. However, it can be truncated if the tool is instructed to do so explicitly. Recover data from multiple files or blocks to a single

In the previous article (link), Xiao Zaojun introduced the development history of broadband technology from ISDN, xDSL to 10GPON. Today, let’s talk about the upcoming new generation of optical fiber broadband technology-50GPON. █F5G and F5G-A Before introducing 50GPON, let’s talk about F5G and F5G-A. In February 2020, ETSI (European Telecommunications Standards Institute) promoted a fixed communication network technology system based on 10GPON+FTTR, Wi-Fi6, 200G optical transmission/aggregation, OXC and other technologies, and named it F5G. That is, the fifth generation fixed network communication technology (The5thgenerationFixednetworks). F5G is a fixed network
Google is ecstatic: JAX performance surpasses Pytorch and TensorFlow! It may become the fastest choice for GPU inference training
Apr 01, 2024 pm 07:46 PM
The performance of JAX, promoted by Google, has surpassed that of Pytorch and TensorFlow in recent benchmark tests, ranking first in 7 indicators. And the test was not done on the TPU with the best JAX performance. Although among developers, Pytorch is still more popular than Tensorflow. But in the future, perhaps more large models will be trained and run based on the JAX platform. Models Recently, the Keras team benchmarked three backends (TensorFlow, JAX, PyTorch) with the native PyTorch implementation and Keras2 with TensorFlow. First, they select a set of mainstream
Slow Cellular Data Internet Speeds on iPhone: Fixes
May 03, 2024 pm 09:01 PM
Facing lag, slow mobile data connection on iPhone? Typically, the strength of cellular internet on your phone depends on several factors such as region, cellular network type, roaming type, etc. There are some things you can do to get a faster, more reliable cellular Internet connection. Fix 1 – Force Restart iPhone Sometimes, force restarting your device just resets a lot of things, including the cellular connection. Step 1 – Just press the volume up key once and release. Next, press the Volume Down key and release it again. Step 2 – The next part of the process is to hold the button on the right side. Let the iPhone finish restarting. Enable cellular data and check network speed. Check again Fix 2 – Change data mode While 5G offers better network speeds, it works better when the signal is weaker
The vitality of super intelligence awakens! But with the arrival of self-updating AI, mothers no longer have to worry about data bottlenecks
Apr 29, 2024 pm 06:55 PM
I cry to death. The world is madly building big models. The data on the Internet is not enough. It is not enough at all. The training model looks like "The Hunger Games", and AI researchers around the world are worrying about how to feed these data voracious eaters. This problem is particularly prominent in multi-modal tasks. At a time when nothing could be done, a start-up team from the Department of Renmin University of China used its own new model to become the first in China to make "model-generated data feed itself" a reality. Moreover, it is a two-pronged approach on the understanding side and the generation side. Both sides can generate high-quality, multi-modal new data and provide data feedback to the model itself. What is a model? Awaker 1.0, a large multi-modal model that just appeared on the Zhongguancun Forum. Who is the team? Sophon engine. Founded by Gao Yizhao, a doctoral student at Renmin University’s Hillhouse School of Artificial Intelligence.
The U.S. Air Force showcases its first AI fighter jet with high profile! The minister personally conducted the test drive without interfering during the whole process, and 100,000 lines of code were tested for 21 times.

Recently, the military circle has been overwhelmed by the news: US military fighter jets can now complete fully automatic air combat using AI. Yes, just recently, the US military’s AI fighter jet was made public for the first time and the mystery was unveiled. The full name of this fighter is the Variable Stability Simulator Test Aircraft (VISTA). It was personally flown by the Secretary of the US Air Force to simulate a one-on-one air battle. On May 2, U.S. Air Force Secretary Frank Kendall took off in an X-62AVISTA at Edwards Air Force Base. Note that during the one-hour flight, all flight actions were completed autonomously by AI! Kendall said - "For the past few decades, we have been thinking about the unlimited potential of autonomous air-to-air combat, but it has always seemed out of reach." However now,
