The Cisco Nexus series switches are modular and fixed port network switches designed for the data center. Cisco Systems introduced the Nexus Series of switches on January 28, 2008. The first chassis in the Nexus 7000 family is a 10-slot chassis with two supervisor engine slots and eight I/O module slots at the front, as well as five crossbar ...
[53] [54] [55] It is available both as a web application and as a downloadable program for Windows, Linux, and macOS. More advanced free emulators are available from the GXemul (formerly known as the mips64emul project) and QEMU projects. These emulate the various MIPS III and IV microprocessors in addition to entire computer systems which use ...
The Cisco IOS monolithic kernel does not implement memory protection for the data of different processes. The entire physical memory is mapped into one virtual address space. The Cisco IOS kernel does not perform any memory paging or swapping. Therefore the addressable memory is limited to the physical memory of the network device on which the ...
An example CCIE ceramic plaque. The Cisco Certified Internetwork Expert, or CCIE, is a technical certification offered by Cisco Systems.The Cisco Certified Internetwork Expert (CCIE) and Cisco Certified Design Expert (CCDE) certifications were established to assist the industry in distinguishing the top echelon of internetworking experts worldwide and to assess expert-level infrastructure ...
A Cisco rollover cable using the 8P8C Yost standard 8P8C connectors are also used in many devices. The EIA/TIA-561 standard defines a pinout using this connector, while the rollover cable (or Yost standard) is commonly used on Unix computers and network devices, such as equipment from Cisco Systems .
Early ASICs used gate array technology. By 1967, Ferranti and Interdesign were manufacturing early bipolar gate arrays. In 1967, Fairchild Semiconductor introduced the Micromatrix family of bipolar diode–transistor logic (DTL) and transistor–transistor logic (TTL) arrays.
Options on the IBM PC and XT were set by switches and jumpers on the main board and on expansion cards. Starting around the mid-1990s, it became typical for the BIOS ROM to include a "BIOS configuration utility" (BCU [ 17 ] ) or "BIOS setup utility", accessed at system power-up by a particular key sequence.
Intel PRO/1000 GT PCI network interface controller. In computer networking, Gigabit Ethernet (GbE or 1 GigE) is the term applied to transmitting Ethernet frames at a rate of a gigabit per second. The most popular variant, 1000BASE-T, is defined by the IEEE 802.3ab standard.
