information arriving at the receive end may be erroneous. Channel coding is introduced to restore information to the maximum extent at the receive end, thereby reducing the bit error rate. WLAN uses two channel coding schemes: Binary Convolutional Encoding (BCC) and Low Density Parity Check (LDPC...
A codec is a hardware- or software-based process that compresses and decompresses large amounts of data. Codecs are used in applications to play and create media files for users, as well as to send media files over a network. The term is a blend of the wordscoderanddecoder, as well ...
FreeSync syncs a monitor’s refresh rate to match the rate at which your graphics card produces new frames. The end result is very similar. The main difference between the two is price. FreeSync is built using the Adaptive Sync Standard. This is an open standard that other manufacturers can...
A smart home is an automated and connected home. Multiple functional features of the residence -- lights, heat, door locks, etc. -- can operate on their own, in concert with each other, or under the control of a central hub or mobile command program or app. There's even a special na...
Cryptography is the process of hiding or coding information so only the intended recipient can read a message. Discover how cryptography works and the potential risks it poses.
TCP is typically the more reliable protocol; however, UDP has a faster transmission time. UDP is used when speed takes precedence over reliability, while TCP is used when reliability takes precedence. Many consumer streaming services use TCP, for example, while UDP is well suited for video confe...
SQL injection vulnerabilities are typically the result of insecure coding practices. It is relatively easy to prevent SQL injection if coders use secure mechanisms for accepting user inputs, which are available in all modern database systems. Learn more in the detailed guide to SQL injection Key ...
queries. Typically, these are queries created as an extension ofweb application forms, or received via HTTP requests. Any database system is vulnerable to these attacks, if developers do not adhere to secure coding practices, and if the organization does not carry out regular vulnerability testing...
