🏝🏝🔺 COMPUTER : ONE LINER🔺🏝🏝 ════════════♢.✰.♢═════════════ 📍📍Debugging is the process of fixing a bug in the software. 📍📍Testing is the process to find bugs and errors in software. ⚡️⚡️ENIAC, short for Electronic Numerical Integrator And Computer,was the first general-purpose electronic computer. 🔹🔹Invented By :- J Presper Eckert And John Mauchly ⚡️⚡️EDVAC (Electronic Discrete Variable Automatic Computer) was one of the earliest electronic computers. Unlike its predecessor the ENIAC, it was binary rather than decimal, and was a stored program machine. 🔹🔹Invented By :- J Presper Eckert And John Mauchly ⚡️⚡️UNIVAC, which stood for Universal Automatic Computer, was developed by J. Presper Eckert and John Mauchly, makers of ENIAC, the first general-purpose electronic digital computer. These giant computers, which used thousands of vacuum tubes for computation, were the forerunners of today’s digital computers. 🔹🔹Invented By :- J Presper Eckert And John Mauchly ⚡️⚡️First Computer virus - “Creeper "- at the time of ARPANET Created by BBN technology, US ⚡️⚡️First Universally Accepted Computer virus - "Brain" - In MS-DOS OS ( Infected through 5.2" floppy Disc) Created by of two brothers, Basit and Amjad Farooq Alvi #important
