Cisco router has become a commonly used network device, but we are not very clear about its storage classification. Here we will introduce it in detail. Memory category: 1: RAM: Random Access to memory, equivalent to computer memory 2: ROM: read-only memory.

CHAP verifies the identity of the authenticated end through a three-way handshake. It is completed when the initial link is established. To improve security, it is periodically verified after the link is established. CHAP is safer than PAP because CHAP does not send plain text online, but instead sends a random number s
