ALL ABOUT COMPUTERS
The History of computers
The history of computers is: The first ever computer is an ENIAC machine by John W. Mauchly and J. Presper Eckert at the University of Pennsylvania. ENIAC (Electrical Numerical Integrator and Calculator) used a word of 10 decimal digits instead of binary ones like previous automated calculators/computers. ENIAC was also the first machine to use more than 2,000 vacuum tubes, using nearly 18,000 vacuum tubes. Storage of all those vacuum tubes and the machinery required to keep the cool took up over 167 square meters (1800 square feet) of floor space. Nonetheless, it had punched-card input and output and arithmetically had 1 multiplier, 1 divider-square rooter, and 20 adders employing decimal "ring counters," which served as adders and also as quick-access (0.0002 seconds) read-write register storage.
What is an ENIAC Machine
ENIAC was the first electronic general-purpose computer. It was Turing-complete digital and capable of being reprogrammed to solve a large class of numerical problems Introduced to the world on: February 15, 1946.
- Internal storage is: The Storage on any device which is on the actual device like when you buy a new phone or computer and it has 16 GB, 4GB or 8GB already on the device. The good things about internal storage are: you have some storage already on the device however the bad things are when its used up you can’t use any more then you’ll have to buy more storage.
- External storage is something which is put into a device like a USB/pen drive SD card or any information which can come in and out of the device. The good thing about an external storage is you can add more storage to the device. The bad thing is if it gets lost you lose everything.
Extra for experts. - The types of storage mobile phones use are internal and external storage because they already have a certain amount of storage on them and you could add more by putting an SD card in (for android users) or by buying it online (for apple users).
