    A gaming computer, also known as a gaming PC, is a specialized personal computer designed for playing PC games at high standards. They typically differ from mainstream personal computers by using high-performance graphics cards , a high core-count CPU with higher raw performance and higher-performance RAM .

    The price rapidly dropped, creating a price war and causing the departure of numerous companies from the home computing market. Total C64 sales during its lifetime (from 1982 to 1994) are estimated at more than 17 million units [citation needed], making it the best-selling computer model of all time. October 1982 US

  6. Read-only memory - Wikipedia

    en.wikipedia.org/wiki/Read-only_memory

    ROM and RAM are essential components of a computer, each serving distinct roles. RAM, or Random Access Memory, is a temporary, volatile storage medium that loses data when the system powers down. In contrast, ROM, being non-volatile, preserves its data even after the computer is switched off. [2]

    This computer is the first to allow interactive computing, allowing users to interact with it using a keyboard and a cathode-ray tube. The Whirlwind design was later developed into SAGE, a comprehensive system of real-time computers used for early warning of air attacks. 17 Nov 1951: UK

  8. Memory hierarchy - Wikipedia

    en.wikipedia.org/wiki/Memory_hierarchy

    Since response time, complexity, and capacity are related, the levels may also be distinguished by their performance and controlling technologies. [1] Memory hierarchy affects performance in computer architectural design, algorithm predictions, and lower level programming constructs involving locality of reference .

    Xbox 360 was the first high-definition gaming console to utilize the ATI Technologies 256-bit GPU Xenos [2] before the introduction of the current gaming consoles especially Nintendo Switch. Some buses on the newer System on a chip (e.g. Tegra developed by Nvidia ) utilize 64-bit, 128-bit, 256-bit, or higher.
