Answer:
Computer scientists began building rudimentary games and simulations on mainframe computers in the 1950s and 1960s, with MIT's Spacewar! in 1962 being one of the first such games to be played with a video display. The first consumer-ready video game hardware arrived in the early 1970s, with the Magnavox Odyssey, the first home video game system, and the first arcade video games from Atari, Computer Space and Pong, the latter of which was later transformed into a home console version. Pong's success in arcades and at home prompted numerous firms to create clones of the game, resulting in a market contraction in 1978 owing to oversaturation and a lack of innovation.
Answer:
The four types of maintenance in IT are given as:
Preventive maintenance: It is the important part to facilitates the management system and it should be designed carefully o prevent them from failure. the main aim of preventive maintenance is to successfully establish the design to improve the system performance.
Corrective maintenance: It basically refers to the changes made to repair the defects in the implementation and designing of the system. It is usually performed after the failure occur in the equipment. It also increased overall productivity of the system.
Perfective maintenance: It basically improve the performance of the system, efficiency and maintainability. This type of maintenance are initiated by the IT department.
Adaptive maintenance: It involves the implementation changes in the system to increase its functionality. It basically improve its efficiency and increase its capability. It is less urgent than corrective maintenance.
