Wireless access points security – Wi-Fi encryption protocols to retire
Nowadays, everyone is aware that the data sent over Wi-Fi can be taken by those that can listen and decode the weakly encrypted Wi-Fi signal. I believe that it’s time to retire weak wireless encryption schemes and do not make them available in option menus of Wi-Fi enabled devices – they truly no longer add any benefit. [Read more…]

Reliability of Solid-State-Disks (SSD)
As we know, the NAND type of memory only allows a finite number of writes. This means that the most pressing issue regarding the reliability of SSD drives (and NAND technology in general) is the life expectancy and durability. [Read more…]
Phase-Change RAM (PCRAM), Resistive RAM (RRAM) and Magnetic RAM (MRAM)
Phase-Change RAM (PCRAM), Resistive RAM (RRAM) and Magnetic RAM (MRAM) are some of the emergent SCM (Storage Class Memory) technologies used for NVM (Non-Volatile Memory). How do these devices actually store binary data, and how do they compare, performance-wise, with standard DRAM/SDRAM devices? [Read more…]
The impacts of the rapid increase in the capacity of non-volatile memory on computer architecture, data processing and storage.
In computer architecture, a term ‘Non-Volatile Memory’ (NVM) is referring to a type of memory that doesn’t require any moving parts to perform the read or write operations, nor it needs to refresh its content periodically in order to keep it stored. [Read more…]
