What is Encoding? Why must encoding be used for data transmission? (1)【什么是编码?】Convert internal data of a sender into line signals suitable for transmission is calledencoding. (2)【数据发送时为什么要编码?】 1) Electromagnetic signals in information process devices are not allowed transm...
e.g. binary data being sent over email, or viewing special characters on a web page. The goal is not to keep information secret, but rather to ensure that it's able to be properly consumed.
What methods can be used to transmit data between two UIAbility components? Does a crash of an ExtensionAbility process cause a crash of the main process? How do I check whether a UIAbility is visible or has focus during its lifecycle in the stage model? Do multiple UIAbility component...

HSADC and DMA for data transmission, I tried to modify the DMA transmission data size, but has not been successful, the transmission of data has been 4095, which is why, if you know, I am here to thank you first, the followingWhy can't I set the transfer size of DMA my code:vo...
ASCII or American Standard Code for Information Interchange is a digital character encoding standard. It implements of a seven bit width binary code for digital characters numbered from 0 to 127. It was considered for an eight-bit code but ...
It can provide real-time reliable messaging services for network-connected devices with minimal code. MQTT protocol is widely used in IoT, Mobile Internet, Smart Hardware, Internet of Vehicles, Smart Cities, Telemedicine, Power, Oil, Energy, and other fields. MQTT was created by Andy Stanford-...
Then, we’ll understand the standardization of the big-endian in the TCP/IP protocol and its advantages. 2. Endianness Computers use groups of binary bits of different sizes to store data. Bytes are the main structure, i.e., a byte comprises 8 bits and represents the smallest data group ...
I am way behind in my work, but I just cannot resist trying to answer your question on why a "byte" has eight bits. The answer is that some do, and some don't. But that takes explaining, as follows: If computers worked entirely in binary (and some did a long time ago), and di...
IPv6 is a network layer protocol that functioned to the multiple IP-based networks during data transmission. It can be used to identify devices on the internet and thus locate them since IPv6 is the latest version of Internet Protocol. Internet communication on any device requires a unique IP...
