VAX is a series of computers featuring a 32-bit instruction set architecture (ISA) and virtual memory that was developed and sold by Digital Equipment Corporation (DEC) in the late 20th century. The VAX-11/780, introduced October 25, 1977, was the first of a range of popular and influential computers implementing the VAX ISA. The VAX family was a huge success for DEC, with the last members arriving in the early 1990s. The VAX was succeeded by the DEC Alpha, which included several features from VAX machines to make porting from the VAX easier.
The 4th millennium BC spanned the years 4000 BC to 3001 BC. Some of the major changes in human culture during this time included the beginning of the Bronze Age and the invention of writing, which played a major role in starting recorded history.
The Athlon 64 X2 is the first native dual-core desktop central processing unit (CPU) designed by Advanced Micro Devices (AMD). It was designed from scratch as native dual-core by using an already multi-CPU enabled Athlon 64, joining it with another functional core on one die, and connecting both via a shared dual-channel memory controller/north bridge and additional control logic. The initial versions are based on the E stepping model of the Athlon 64 and, depending on the model, have either 512 or 1024 KB of L2 cache per core. The Athlon 64 X2 can decode instructions for Streaming SIMD Extensions 3 (SSE3), except those few specific to Intel's architecture. The first Athlon 64 X2 CPUs were released in May 2005, in the same month as Intel's first dual-core processor, the Pentium D.
The VAXstation is a discontinued family of workstation computers developed and manufactured by Digital Equipment Corporation using processors implementing the VAX instruction set architecture. VAXstation systems were typically shipped with either the OpenVMS or ULTRIX operating systems. Many members of the VAXstation family had corresponding MicroVAX variants, which primarily differ by the lack of graphics hardware.
The CDC 3000 series are a family of mainframe computers from Control Data Corporation (CDC). The first member, the CDC 3600, was a 48-bit system introduced in 1963. The same basic design led to the cut-down CDC 3400 of 1964, and then the 24-bit CDC 3300, 3200 and 3100 introduced between 1964 and 1965. The 3000 series replaced the earlier CDC 1604 and CDC 924 systems.
SIMH is a free and open source, multi-platform multi-system emulator. It is maintained by Bob Supnik, a former DEC engineer and DEC vice president, and has been in development in one form or another since the 1960s.
The NVAX is a CMOS microprocessor developed and produced by Digital Equipment Corporation (DEC) that implemented the VAX instruction set architecture (ISA). A variant of the NVAX, the NVAX+, differed in the bus interface and external cache supported, but was otherwise identical in regards to microarchitecture. The NVAX+ was designed to have the same bus as the DECchip 21064, allowing drop-in replacement.
The MicroVAX is a discontinued family of low-cost minicomputers developed and manufactured by Digital Equipment Corporation (DEC). The first model, the MicroVAX I, was first shipped in 1984. They used processors that implemented the VAX instruction set architecture (ISA) and were succeeded by the VAX 4000. Many members of the MicroVAX family had corresponding VAXstation variants, which primarily differ by the addition of graphics hardware. The MicroVAX family supports Digital's VMS, ULTRIX and VAXELN operating systems. Prior to VMS V5.0, MicroVAX hardware required a dedicated version of VMS named MicroVMS.

The VAX 4000 is a discontinued family of low-end superminicomputers developed and manufactured by Digital Equipment Corporation using microprocessors implementing the VAX instruction set architecture (ISA). The VAX 4000 succeeded the MicroVAX family, and shipped with the OpenVMS operating system. It was the last family of low-end VAX systems, as the platform was discontinued by Compaq.
The VAXft was a family of fault-tolerant minicomputers developed and manufactured by Digital Equipment Corporation (DEC) using processors implementing the VAX instruction set architecture (ISA). "VAXft" stood for "Virtual Address Extension, fault tolerant". These systems ran the OpenVMS operating system, and were first supported by VMS 5.4. Two layered software products, VAXft System Services and VMS Volume Shadowing, were required to support the fault-tolerant features of the VAXft and for the redundancy of data stored on hard disk drives.
The VAXserver was a family of minicomputers developed and manufactured by Digital Equipment Corporation (DEC) using processors implementing the VAX instruction set architecture (ISA). The VAXserver models were variants of various VAX-based computers which were configured to only run operating systems which were licensed for network server use and not interactive time-sharing use. This was accomplished with different CPU modules and firmware.
The Digital Storage Systems Interconnect (DSSI) is a computer bus developed by Digital Equipment Corporation for connecting storage devices and clustering VAX systems. It was designed as a smaller and lower-cost replacement for the earlier DEC Computer Interconnect that would be more suitable for use in office environments. DSSI was superseded by Parallel SCSI.
Rigel was a microprocessor chip set developed and fabricated by Digital Equipment Corporation (DEC) that implemented the VAX instruction set architecture (ISA). It was introduced on 11 July 1989 with the introduction of the VAX 6000 Model 400, the first system to feature the chip set. Rigel was also used in the VAX 4000 Model 300 and VAXstation 3100 Model 76. Production Rigel CPUs were rated at 35 to 43 MHz.

And there is only five General Post Offices in Bangladesh, They are: Central General Post office, Dhaka GPO assigned Code is 1000, Metropolitan General Post office, Metropolitan Dhaka assigned code is 1100, Eastern General Post officeChattogram GPO assigned Code 4000, Northern General Post office, Rajshahi GPO assigned Code 6000 and Southern General Post office, Khulna GPO assigned Code is 9000.
Postal Codes in Albania consist of 4 digits; the first two digits show the branch on a district level located at the center of that administrative level, whereas the second two digits show the postal office offering service to a defined administration unit on a municipality level:
The Horse, the Wheel, and Language: How Bronze-Age Riders from the Eurasian Steppes Shaped the Modern World is a 2007 book by the anthropologist David W. Anthony, in which the author describes his "revised Kurgan theory." He explores the origins and spread of the Indo-European languages from the Pontic–Caspian steppe throughout Western Europe, Central Asia, and South Asia. He shows how the domesticated horse and the invention of the wheel mobilized the steppe herding societies in the Eurasian Steppe, and combined with the introduction of bronze technology and new social structures of patron-client relationships gave an advantage to the Indo-European societies. The book won the Society for American Archaeology's 2010 Book Award.
Aurizon electric locomotives are used by Australian rail operator Aurizon in Queensland.
3500 South MAX was a bus rapid transit (BRT) line in northwestern Salt Lake County, Utah, United States, operated by the Utah Transit Authority (UTA) that ran between Magna, West Valley City, and South Salt Lake. It opened for service on July 14, 2008, and was the first of several BRT lines that UTA is planning in the Salt Lake Valley, Weber County, and Utah County.
