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 byte is abbreviated with a B. (A bit is abbreviated with a small b.) Computer storage is usually measured in byte multiples. For example, an 820 MB hard drive holds a nominal 820 million bytes-or megabytes-of data. Byte multiples are based on powers of 2 and commonly expressed as a rounded off decimal number. For example, one megabyte (one million bytes) is actually 1,048,576 (decimal) bytes.
