In communications, codecs can be hardware- or software-based. Hardware-based codecs perform analog-to-digital anddigital-to-analog conversions. A common example is a modem used to send data traffic over analog voice circuits. In this case, the termcodecis a blend ofcoder/decoder. Software-ba...
What is the difference between a bit and a byte? A bit is the smallest unit of digital information and can have a value of either 0 or 1. A byte, on the other hand, is a group of bits that is typically composed of eight bits. Bytes are used to represent larger amounts of informa...
A bit is represented by a lowercase b. While a byte can hold a letter or symbol, a bit is the smallest unit of storage, storing just onebinarydigit. The standard number of bits in a byte is eight, but that number can vary from system to system, depending on the hardware. Fred Brook...
IPv4:IPv4 is the fourth version of the Internet Protocol, and it’s the most widely used. It assigns a 32-bit address to devices (like 192.168.1.1), allowing for about 4.3 billion unique addresses. IPv6:IPv6 is the newer version of the Internet Protocol, designed to replace IPv4. It ...
What Is A Codec Bit Rate? We’ve mentioned bit rate a few times, so before we get into the technical details of how codecs actually work, let’s define bit rate. Bit rate is the measure of how much a codec has compressed a video clip. It’s usually expressed as data amount per ...
A QR code is a square barcode that can contain information such as a URL, Wi-Fi password, or contact card, and it can be scanned easily by a smartphone camera. You've probably seen QR codes---those black and white boxes with small squares arranged in seemingly random patterns. It's ...
Timing pattern:An L-shaped line that helps to identify individual squares within the whole code, making it possible for a damaged QR code to be read. Version information:Identifies which version of the QR code is being read. Data cells:The rest of the QR code communicates the actual informat...
