GHB (gamma-hydroxybutyrate) is produced naturally in the human body in very small amounts. When taken as a recreational drug, and especially when taken in combination with alcohol or other drugs, GHB can be extremely dangerous.
TCP Checksum is a 16-bit field in TCP header used for error detection. It is computed over the TCP segment (might plus some padding) and a 12-byte TCP pseudo header created on the fly. Same as IP checksum, TCP checksum is also oneâs complement of the oneâs complement sum of all 16 bit words in the computation data.
For example, if you download a Code 39 barcode, then you would type *Hello* to create a scannable barcode that will read the word Hello when scanned. If you want to include a space in a Code 39 barcode, you have to use the equals symbol (=). So, you would have to type *Hello=John* in Word to get the text Hello John when scanned. For Code 128, itâs not that simple. In addition to start and stop symbols, you also need some special checksum characters.
