A transistor computer often referred to as a second-generation computer, is a type of computer that, as opposed to vacuum tubes, relies on discrete transistors as its principal component to do the processing.
generally known as electromechanical computers or using vacuum tubes. For example, ENIAC has used Vacuum tubes, relied on Machine Language and Boolean logic. A computer using vacuum tubes is very slow in executing programs compared to present-day computers
The first computers were mechanical devices, The first electronic computer was invented in 1937, Vacuum tubes were used in early computers, ENIAC was the first general-purpose electronic computer, ENIAC weighed 27 tons, stood 10ft tall, and took up 1800 square feet of space.
