[6] Packet Tracer also allows instructors to create activities that students have to complete. [citation needed] Packet Tracer is often used in educational settings as a learning aid.
The Cyber-170 series represented CDCs move from discrete electronic components and core memory to integrated circuits and semiconductor memory. The 172, 173, and 174 use integrated circuits and semiconductor memory whereas the 175 uses high-speed discrete transistors. [6] The Cyber-170/700 series is a late-1970s refresh of the Cyber-170 line.
The Cyber 18 series, exploiting the extended instruction set, ran a disk-based OS, the Interactive Terminal Oriented System (ITOS). This system supported Fortran, Cobol, and UCSD Pascal . ITOS was a foreground/background system with multiple users connected via serial CRT terminals; user tasks ran in the background while the operating system ...
A couple of new HAIPE devices will combine the functionality of a router and encryptor when HAIPE IS version 3.0 is approved. General Dynamics has completed its TACLANE version (KG-175R), which house both a red and a black Cisco router, and both ViaSat and L-3 Communications are coming out with a line of network encryptors at version 3.0 and above.
The first member of the CDC 6000 series was the supercomputer CDC 6600, designed by Seymour Cray and James E. Thornton [23] in Chippewa Falls, Wisconsin.It was introduced in September 1964 and performs up to three million instructions per second, three times faster than the IBM Stretch, the speed champion for the previous couple of years.
