11. 1954 IBM 704
In 1954, the IBM 704 was built, the 704 computer was the first to have indexing, floating point arithmetic, and an improved reliable magnetic core memory.12. 1955 Transistor Based Computer
In 1955, IBM stopped using vacuum tube technology in their computers and built the 608 transistor calculator, a solid state computer with no tubes.13. 1956 Magnetic Hard Disk Storage
In 1956, the RAMAC 305 and RAMAC 650 machines were built. RAMAC stood for Random Access Method of Accounting and Control machines. RAMAC machines used magnetic hard disks for data storage.14. 1959 10,000 Units Sold
In 1959, the IBM 1401 data processing system was introduced, the first computer ever to achieve sales of over 10,000 units. Also in 1959, the IBM 1403 printer was built.15. 1964 System 360
In 1964, the IBM System 360 family of computers were. System 360 was the world's first family of computers with compatible software and hardware. IBM described it as "a bold departure from the monolithic, one-size-fits-all mainframe," and Fortune magazine called it "IBM's $5 billion gamble."
Courtesy of IBMIn 1944, IBM researcher Robert H. Dennard invented DRAM memory. Robert Dennard's invention of one-transistor dynamic RAM called DRAM was a core development in the launch of today's computer industry, setting the stage for development of increasingly dense and cost-effective memory for computers.
17. 1970 IBM System 370
The 1970 IBM System 370, was the first computer to use virtual memory for the first time.18. 1971 Speech Recognition & Computer Braille
IBM invented its first operational application of speech recognition that "enables customer engineers servicing equipment to "talk" to and receive "spoken" answers from a computer that can recognize about 5,000 words." IBM also develops an experimental terminal that prints computer responses in Braille for the blind.19. 1974 Networking Protocol
In 1974, IBM invents a networking protocol called Systems Network Architecture (SNA). .20. 1981 RISC Architecture
IBM invents the experimental 801. The 901 ia a Reduced Instruction Set Computer or RISC architecture invented by IBM researcher John Cocke. RISC technology greatly boosts computer speed by using simplified machine instructions for frequently used functions.
