Cisco Systems is a pioneer in the design and development of devices for the networking, communications, speech, and consumer electronics. Internetwork Operating System (IOS) is a software for its hardware from Cisco Systems developed. It performs telecommunications switching, routing and network functions tightly integrated with an operating system multithreading. Command Line Interface (CLI) is used for human-computer interaction. A fixed set of multiple commands in Word, which is determined by the operation and user will be provided by Cisco. It also provides technical support for IOS problems.
Microprocessors used by IOS
Most systems use Cisco hardware performance microprocessors and various capacities, depending on the hardware platform. Orion R4600 and Motorola 68030 processors are the most commonly-used. Make decisions to keep routing and bridging, routing tables and the use of system management functions are the main functions of the IOS. For these functions, the microprocessor is to access the system memory. Mapping system memory must be performed by an experienced PC support provider.
Types of memory cards required for IOS
There are four types of system memory by IOS used, read-only memory that is, the random access memory, flash memory and non-volatile random access memory. Each of these memories for various purposes.
Read Only Memory (ROM)
ROM or can be integrated into the microprocessor itself or separate from the microprocessor on the system board. As the name implies, the data can be read from this type of memory, not written. Stored in the ROM IOS software is called when the device is started. The ROM size must be from a service provider based on the size of the IOS version to be decided.
Random Access Memory (RAM)
RAM is the type whose content only when it is activated in the Reserve. The main goal of the RAM for storing data is used by application software. In hardware systems, Cisco IOS system keeps RAM buffers and tables for corporate storage needs.
