What is the right fact about ENIAC?
A
It can perform multiple tasks
B
It weighed 30 tons and had 18.000 vacuum tubes
C
ENIAC was invented in 1954
D
All of the answers are correct
Explanation: 

Detailed explanation-1: -ENIAC lost one vacuum tube roughly every day or two. With almost 18, 000 tubes, locating and replacing the failed one was challenging. Over time, however, the maintenance team developed the skill to fix a problem in just 15 minutes.

Detailed explanation-2: -In fact, the ENIAC used 18, 000 vacuum tubes in order to function, allowing signals to be sent and calculations to be performed more quickly through the use of electrical switching rather than the slower mechanical switching.

Detailed explanation-3: -The machine contained 19, 000 vacuum tubes, 1500 relays, and several hundred thousand resistors, capacitors, and conductors. There were 20 accumulators, each capable of storing a 10 digit number. The ENIAC could perform about 5000 additions or 50 multiplications in one second.

Detailed explanation-4: -The new ENIAC contained 18, 000 vacuum tubes yet its memory was too small for many applications. Since the slow process of reading a program from punched tape would have annihilated its high processing speed, the ENIAC was programmed by wiring it up for a specific problem.
