You are designing an Ethernet router/firewall/network address translatorusing an embedded linux operating system to control the device. One of the things that needs to be stored on a longterm basis in the device is the access log of IP addresses and port numbers that have attempted to access machines behind thedevice. Think of this device as the home router behind yourcable, DSL or FIOS modem. It is desirable to store at least256 IP addresses and port numbers, each requiring about 32 bytes of information. Contrast at least two of the options for thememory technology that might be employed for this access logstorage: static CMOS RAM, dynamic MOS RAM, Flash,electrically alterable ROM or mask programmed ROM.
