1. What is Manchester Mark 1 known for?Pioneering implementation of index registers for efficient memory addressing
2. What is the operational status?Operational by April 1949
3. What is the alternative designation?Manchester Automatic Digital Machine (MADM)
4. Why did people call it an "electronic brain"?Because it could think and solve math problems, like finding Mersenne primes, and the press liked that nickname.
5. How did the Manchester Mark 1 help later computers?It introduced index registers, which made it easier to look up data in memory, and this idea was used in later machines such as the IBM 701 and the Ferranti Mark 1.

Stored-program concept: The architectural principle where computer instructions are held in the same memory as data, enabling flexibility and programmability.
Index registers: Specialized CPU registers that facilitate efficient manipulation of memory addresses, crucial for array processing and loops.
General-purpose computer: A computing device designed to execute a broad range of tasks and applications, as opposed to a special-purpose machine.
Floating-point unit (FPU): A specialized part of a CPU designed to perform arithmetic operations on floating-point numbers, essential for scientific and engineering calculations.
