NFC

	Near Field Communication - a short-range, high-frequency radio communication standard that allows wireless data exchange over distances up to several centimeters. This technology is a simple extension of ISO / IEC 14443 that combines a smart card interface and a reader in one device.
NFC devices can communicate with existing devices in the ISO / IEC 14443 standard, as well as with other NFC devices, and thus are compatible with the existing and already in use infrastructure of public transport and payments.

USB 2.0 is a communication connector that replaces the old serial and parallel ports. It is a universal connection between various external devices, e.g. camera, modem, scanner. USB 2.0 enables transfer speeds up to 60MB/s.

RS232 is an interface that has become a standard that organizes the communication of serial-connected devices. Thanks to it, DTE devices can be connected.

SSD

SSD (solid-state drive), sometimes also a solid state disk - a mass storage device based on flash memory. The basic advantage of SSD is the lack of moving parts. In addition, these disks are characterized by significantly shorter data access time (several dozen times), quieter operation and much more resistant to mechanical damage (caused, for example, by shocks during work or fall from a height). Another issue is the use of SSD memory in industrial computers, where large capacity is not important as it is in the case of classic HDDs, but above all operational reliability and resistance to vibrations. SSD memories in industrial applications do not require capacities of 50-100 GB, because in practice capacities of 512 MB-8 GB are used, and it is enough to keep memory at a relatively low cost.

The advantages and disadvantages of SSD

The biggest disadvantage of SSDs is their price to capacity. HDD disks are more widely available, have a larger capacity and are cheaper. However, as disks with moving mechanical systems have some disadvantages that SSDs do not have.

The advantages of SSDs:

•      less energy consumption - there is no need to drive magnetic discs like in HDD disks,
  
•      minimized failure rate,
  
•      instant data writing and reading - programs, games, system start without delays,
  
•      higher bandwidth - faster data transfer,
  
•      resistance to shocks - the disk with moving mechanical parts may be damaged due to a fall, interrupted by writing or reading data,
  
•      in the event of a sudden power outage, the data stored on the flash memory will not be erased,
  
•      work in a larger temperature range than HDD disks,
  
•      they emit less heat,
  
•      no need to defragment the disk.

Limited lifespan of the SSD

The disadvantages of SSDs are their limited lifespan due to the limited number of data write cycles. There is a type of memory associated with the life of the disk:

•  SLC (Single Level Cell) - 1 cell records 1 data bit,
  
•  MLC (Multi Level Cell) - 1 cell saves 2 bits of data,
  
•  TLC (Triple Level Cell) 1 cell saves 3 bits of data.
