What was the contribution made by Konrad Zuse?
Biography. Konrad Zuse (22 June 1910 Berlin – 18 December 1995 HĂĽnfeld) was a German engineer and computer pioneer. His greatest achievement was the world’s first functional program-controlled Turing-complete computer, the Z3, in 1941 (the program was stored on a punched tape).
Who built the complex number calculator Bell Labs?
Williams, and Stibitz and Williams designed a “complex number calculator.” Lab officials gave the go-ahead, and the Model I, as the machine came to be called, was constructed between April and October 1939 at a cost of about $20,000.
Which software is heart of computer?
Assuming you mean that the CPU (central processing unit) is the brain of the computer system, the heart of the computer system would be the clock signal on the motherboard, which provides a regular beat that allows the CPU to proceed with its work.
What are the two types of memory?
There are basically two kinds of internal memory: ROM and RAM. ROM stands for read-only memory. It is non-volatile, which means it can retain data even without power.
Who is brain of computer?
The CPU is the brain of a computer, containing all the circuitry needed to process input, store data, and output results. The CPU is constantly following instructions of computer programs that tell it which data to process and how to process it.
