Zelenograd (Russian: Зеленоград, IPA: [zʲɪlʲɪnɐˈgrat], lit. 'green city') is a city and administrative okrug of Moscow, Russia. The city of Zelenograd and the territory under its jurisdiction form the Zelenogradsky Administrative Okrug (ZelAO), an exclave located within Moscow Oblast, 37 kilometers (23 mi) north-west of central Moscow, along the M10 highway. Zelenograd is the smallest administrative okrug of Moscow by area, the second-lowest by population, and the largest Moscow exclave by area and by population within Moscow Oblast. Zelenograd, if it were a separate settlement, would be the fifth-largest city in Moscow Oblast and one of the 100 largest cities of Russia. Before the expansion of the territory of Moscow in 2012, Zelenograd occupied second place among the administrative okrugs of Moscow, second only to the Eastern Administrative Okrug, in terms of the share of greenery in its total area (approximately 30%).

Zelenograd was founded in 1958 as a new town in the Soviet Union, and developed as a center of electronics, microelectronics and the computer industry known as the "Soviet/Russian Silicon Valley". It remains an important center of electronics in Russia. The city color is green and its emblematic animal is the squirrel.

Digital Equipment Corporation (DEC /dɛk/ ), using the trademark Digital, was a major American company in the computer industry from the 1960s to the 1990s. The company was co-founded by Ken Olsen and Harlan Anderson in 1957. Olsen was president until he was forced to resign in 1992, after the company had gone into precipitous decline.

The company produced many different product lines over its history. It is best known for the work in the minicomputer market starting in the early 1960s. The company produced a series of machines known as the PDP line, with the PDP-8 and PDP-11 being among the most successful minis in history. Their success was only surpassed by another DEC product, the late-1970s VAX "supermini" systems that were designed to replace the PDP-11. Although a number of competitors had successfully competed with Digital through the 1970s, the VAX cemented the company's place as a leading vendor in the computer space. As microcomputers improved in the late 1980s, especially with the introduction of RISC-based workstation machines, the performance niche of the minicomputer was rapidly eroded.
