Explain byte code
Webcomposed of the instruction op-code, status bits and a register number which points to the “destined” physical register in the register file. Once an operator instruction is tagged, it will identify its operands by tags. The tag can be seen as a data token in tagged dataflow machines [1] where the flow of data token activates instructions’ WebAug 12, 2024 · Thanks to their very similar names, bits and bytes can easily be confused. Bits are primarily used to represent data use and transmission speeds of internet, telephone, and streaming services. The bit rate refers to how many bits are transmitted per second. Bytes, on the other hand, are used to express storage sizes. 1 byte is equal to 8 bits.
