1. The file system on a SIM card is fairly straight forward and is analogous to the file system used on a hard drive. The SIM card file system is well documented by the European Telecommunications Standards Institute (ETSI) and by 3GPP. Review the GSM Technical Specification included with this document. Explain in your own words the file structure used on a SIM card. Be accurate without being overly technical. Imagine having to explain this to non-technical people, i.e., a jury or judge. Keep you explanation under one page.
2. Flash memory is a type of Electronically Erasable Programmable Read Only Memory (EEPROM) chip. Unlike volatile memory, flash memory will store data after power has been stopped. Do some research on flash memory and EEPROMs. Explain in your own words how flash memory works. Be accurate without being overly technical. Imagine having to explain this to non-technical people, i.e., a jury or judge. Keep you explanation under one page.

1. The structure of the file system is considered to be very similar with file system from a regular hard drive. The design specifications and the internal organizational structure is like on a Linux file system, following a hierarchy model, from the root of the file system – also called Master File – to the other lower levels. There is just one MF inside a SIM memory file system. It contains one or more DF (dedicated files), which at its turn may consist of one or more elementary files (EF)....
