Sol. IC were started to be in use from 3rd generation of computers. In third generation of computer, IC (Integrated circuits) was used as the electronic component for computers. The development of IC gave birth to a new field of microelectronics. The main advantage of IC is not only its small size but its superior performance and reliability than the previous circuits. It was first developed by T.S Kilby. This generation of computer has huge storage capacity and higher calculating speed.

Ans.(d)
Sol. BSODs appear when Microsoft Windows encounters a critical error it can’t recover from, requiring a reboot and possibly resulting in lost work. It stands for blue screen of death. Blue screens are generally caused by problems with your computer’s hardware or issues with its hardware driver software. A blue screen occurs when Windows encounters a “STOP Error.” This critical failure causes Windows to crash and stop working

Ans.(b)
