версия операционной системы Windows, выпущенная 24 августа 1995 г. Кодовое название - "Chicago". В отличие от предшествовавшей ей Windows 3.11 это не графическая оболочка над MS-DOS, а самостоятельная полная ОС. Она поддерживает 32-разрядные приложения, вытесняющую многозадачность, протоколы TCP/IP, IPX, SLIP, PPP, Windows Sockets, кроме того, усилен графический интерфейс пользователя. Развитием этой ОС стала Windows 98

Interim Standard 95 (IS-95) was the first ever CDMA-based digital cellular technology. It was developed by Qualcomm and later adopted as a standard by the Telecommunications Industry Association in TIA/EIA/IS-95 release published in 1995. The proprietary name for IS-95 is cdmaOne.
It is a 2G mobile telecommunications standard that uses code-division multiple access (CDMA), a multiple access scheme for digital radio, to send voice, data and signaling data (such as a dialed telephone number) between mobile telephones and cell sites. CDMA transmits streams of bits (PN codes). CDMA permits several radios to share the same frequencies. Unlike TDMA "time division multiple access", a competing system used in 2G GSM, all radios can be active all the time, because network capacity does not directly limit the number of active radios. Since larger numbers of phones can be served by smaller numbers of cell-sites, CDMA-based standards have a significant economic advantage over TDMA-based standards, or the oldest cellular standards that used frequency-division multiplexing.
In North America, the technology competed with Digital AMPS (IS-136, a TDMA technology). It was supplanted by IS-2000 (CDMA2000), a later CDMA-based standard.
