What does Flash memory mean?
Flash memory, also known as flash storage, is a type of nonvolatile memory that erases data in units called blocks and rewrites data at the byte level. Flash memory retains data for an extended period of time, regardless of whether a flash-equipped device is powered on or off.
What are the features of node MCU?
NodeMCU has 128 KB RAM and 4MB of Flash memory to store data and programs. Its high processing power with in-built Wi-Fi / Bluetooth and Deep Sleep Operating features make it ideal for IoT projects. NodeMCU can be powered using a Micro USB jack and VIN pin (External Supply Pin).
How many versions of ESP8266 are available?
There are different versions available: a four pin version that only has 3.3V, GND, RX and TX. Over the later ones you talk with your Arduino. Another version has an additional reset pin which allows you to manually or programatically reset the module.
Which is an example of flash memory?

How can you tell if a USB flash drive is real?
Once a USB flash drive or an SD card is purchased, it is a good idea to check if the announced capacity of a device is real or fake (as a system may show a wrong size).
How to determine flash memory size on Arduino?
Arduino’s ESP8266 support includes an example sketch called CheckFlashConfig. This probes the board, and prints the flash memory size.
How big can a 2GB flash drive be?
The 2GB storage capacity is capable of holding up to 50,000 document files and 500 minutes’ worth of music. However, it’s not large enough to contain large video files such as.MP4s and other formats. 4GB With twice the amount of space as the 2GB flash drive, the 4GB thumb drive is ideal for more moderate use.
