Also I do not know much about these chips can anyone tell me what these are used for? Or maybe what other industry uses these chips
It's a FPGA chip( field-programmable gate array). In other words it's for building a algorithm/ASIC prototyping and so on. Nothing for the average Joe.
You can check more info abut FPGA on Wiki https://en.wikipedia.org/wiki/Field-programmable_gate_array or even on https://www.electronics-notes.com/articles/electronic_components/programmable-logic/fpga-what-is-field-programmable-gate-array-basics.php (they explainded the FPGA very well).
