Microcom Networking Protocol problem, additional "framing" bits are added to either end of every byte, typically one bit on either side known as the "start and stop bits". This guarantees at least one 1-to-0 transition for every byte, more than enough to keep the clocks locked. However, these bits also expand every 8 bits of data (one byte) to 10 bits, an overhead of 20%. When using a file transfer protocol, the packets themselves offer their own framing. The packets will always send a continuous stream of data, so the clock cannot "drift" in the same way that it could for data being
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.
