The American National Standards Institute (ANSI) decided in 1963, system of the character code for information interchange. In 1967 International Organization for Standardization (ISO) with almost same ones as the International Standard “ISO 646” of the mark for information interchange which is decided. It is expressed at 7 bits, the alphabetical character of 128 types, consists of the number, the sign and the control code. But actually in order 1 letters 8 bits (1 bytes) with to express, to handle the letter of 256 types it is possible the computer, the letter which differs depending upon the computer manufacturer and the country is recorded in the extended territory of 128 letters where ASCII has not decided. In Japan, it is standardized the code which recorded [kana] letter in the extended territory as “JIS X 0201”.

The keyboard and the mouse, one of standard of the channel which ties peripheral device and the personal computer such as modem and joystick. It was thrown with the standard name, USB 1.1 as a standard in order to connect the equipment which excessively does not exchange the data of bulk with the substance. But, the start-up of IEEE 1394 which is planned at the beginning as high-speed serial interface was late, transfigured in the interface where also result, CD-R and HDD etc where at that time the spread of USB 1.1 advances explosively dangle. But, as for USB 1.1 being highest, 12Mbps (=1.5MB/s) with because it is the standard which can do transfer rather at only the low speed which is said, USB 2.0 (HI-SPEED USB) was decided the fact that demand for high-speed transfer is satisfied as a purpose.

eripheral device and the like. It is the USB standard which presently is used most widely, the most general personal computer - is interface between the peripheral device.

USB 1.0 which is the first version of USB was announced in 1996 January, USB 1.1 which improves this was announced in 1998 September.

As for USB 1.1, such as specification of electric power consumption in the peripheral device mainly stipulates the point which is ambiguous with the specification in USB 1.0 strictly, it is something which.

The transfer standard of USB 1.1 LS (Low Speed) mode (1.5Mbps), FS (FULL Speed) mode (12Mbps) consists of 2 types, as for each peripheral device can use properly these two transmission modes.
