What are two characteristics of RAM on a Cisco device?
Answer: The data which assists in the operation of the network is stored by the RAM. An active running configuration on the devices is contained in RAM. In the process of the power cycle, the RAM data is lost because RAM is the volatile memory. The versions of the IOS are in the flash memory which in return makes a copy of it in the RAM when the system is turned off. Unlike RAM, flash memory is nonvolatile because the data is not lost when the system is shut down.
Cisco OS runs on the Cisco router switches, and the goal of it is to enable communication among the nodes. There is total of four types of memory in the Cisco devices which are listed below:
RAM:
RAM is the system volatile memory that handles the active task running on the system. it is an essential component and any kind of program, or file is useless without it. RAM is the fastest and most temporary storage which is used by the computer even now.
ROM:
Unlike RAM, it is the permanent storage of the data on PCs and other devices.it is tough to change or modify only the manufacturers can do it. Some of the ROM types can be rewritten but at a slow speed.
Flash memory:
Nonvolatile memory is programmed in a specific place known as the block. The content of the flash memory is erasable and the data is retained even if the power supply is not present.it is costly and slow.
NVRAM:
NVRAM is the extension of the RAM and contains the data during the power down.it uses the tiny 24-pin DIP integrated chips whose work is to obtain the power for the working from the CMOS battery which exists on the motherboard.
