Computer number format still split that memory into eight-bit pieces. This is called byte-addressable memory. Historically, many CPUs read data in some multiple of eight bits. Because the byte size of eight bits is so common, but the definition is not standardized, the term octet is sometimes used to explicitly describe an eight bit sequence. A "nibble" (sometimes "nybble"), is a number composed of four bits. Being a half-byte, the nibble was named as a play on words. A person may need several nibbles for one bite from something; similarly, a nybble is a part of a byte. Because four bits allow for
Walkie bits Walkie bits Walkie Bits are little plastic toy turtles that sing, dance and walk (they can walk in the rhythm which you tap on their shell). They are made by Takara, a Japanese toy company in June 2005. Walkie Bits are very small, only about five centimeters, and come in a variety of different colors and "flavors" like "blue soda" and "green pineapple". The Walkie Bits turtles are very popular in Japan, with 300,000 units sold within just a few months of their release. Many Japanese people collect them because there are so many colors and they are relatively inexpensive.
