DO YOU KNOW?

1. Early electronic computers, developed around the 1940’s, were the size of a large room and consumed huge amounts of electricity.They were vastly different to the modern computers we use today, especially when compared to small and portable laptop computers. 









2. A computer’s memory stores numbers in huge amounts of cells that are addressed and can be quickly accessed by the CPU to perform calculations. There are two main types of computer memory, ROM (read only memory) and RAM (random access memory).  ROM contains pre-written software and data that the CPU can only read, while RAM can be accessed and written to at any time.
