Sense Organs. The nervous system is responsible for sensing the external and internal environments of an organism, and for inducing muscle movement. Human sensation is achieved through the stimulation of specialized neurons, organized into five different modalitiesâtouch, balance, taste, smell, hearing, and vision.
A byte is a sequence of bits. In computer networking, some network protocols send and receive data in the form of byte sequences. These are called byte-oriented protocols. Examples of byte-oriented protocols include TCP/IP and telnet. The order in which bytes are sequenced in a byte-oriented network protocol is called the network byte order. The maximum size of a single unit of transmission for these protocols, the Maximum Transmission Unit (MTU), is also measured in bytes. Network programmers routinely work both with network byte ordering and MTUs.
A sequence of bits can represent not just numbers but other kinds of data, such as the letters and symbols on a keyboard. The sequence of 0s and 1s that make up data are usually counted in groups of 8, and these groups of 8 bits are called bytes. The word byte is short for binary digit eight. To transmit one keystroke on a typical keyboard requires one byte of information (or 8 bits). To transmit a three-letter word requires three bytes of information (or 24 bits). In computer technology, a unit of information made up of bits (often eight bits).
