What does FPGA stand for?

FPGA stands for Field-Programmable Gate Array. This term reflects the primary characteristics of FPGAs, which are integrated circuits designed to be configured by the customer or designer after manufacturing — hence "field-programmable." The "gate array" part refers to the array of logic gates that can be arranged and customized to perform a variety of functions.

FPGAs are utilized in various applications, from simple logic implementations to complex digital signal processing tasks, thanks to their flexibility and adaptability. Users can program the hardware to carry out specific functions, allowing for a wide range of functionalities in diverse environments, making them valuable in prototyping and custom hardware solutions.

The other options provided do not accurately describe FPGAs. For instance, "Fully-Planned Gate Array" and "Flexible Programmable Gate Architecture" do not reflect the standard terminology used in digital electronics. Additionally, "Field-Programmable Group Array" does not convey the comprehensive capabilities and definitions associated with FPGAs. Understanding the correct term helps in associating the technology with its applications and advantages in the field of digital electronics.
