Transistors were first developed in 1947 by Bell Telephone laboratories. They replaced vacuum tubes, which were big, bulky, costly, and unreliable. Transistors are most often used to regulate the flow of an electrical current and to switch electricity on and off.

Why did the Colossus computer need valves?
the first electronic computers were built before the invention of the transistor or integrated circuit chip. They used vacuum tubes for the processing and temporary memory. In Britain those tubes were called valves.
What technology replaced vacuum tubes in the second generation?
Vacuum tubes were first replaced by transistors, and later by integrated circuits.
What are computer tubes used for?
Computer tubes, also known as vacuum tube computers are programmable computers that uses vacuum tube logic circuitry. They were used to solve computational problems much like modern day computers.
What key materials were used in the first generation computers?
VACUUM Tubes were first used as Logical Components in firstmanufactured Computers. Then the Invention of Transistors changed the Computing Industry and now the miniature form of Transistors ranging in nanometers (for e.g. 65nm or 45nm based processors).
Which invention allowed computer to be smaller?
Microchip
What roles has vacuum tubes played in computer development?
vacuum tubes are the switching components in the first generation computers to process data. later they were replaced by transistors.
Why did the Colossus computer need valves?

What technology replaced vacuum tubes in the second generation?
Vacuum tubes were first replaced by transistors, and later by integrated circuits.
What is the usage and benefit of vacuum tube in computer?
Vacuum tubes are neither useful nor advantageous in modern computers. These were replaced decades ago by the integrated circuit.
Did Alan Turing made the vacuum tubes computers?
No, he had to use mechanical gears, etc. because they were the only device technology available in his time. Electric relays were first developed about 15 years after he designed his computer, while vacuum tubes were first developed about 90 years after he designed his computer.
What computers will used vacuum tubes?
First generation computers.
Who is the first generation of computers?
vacuum tubes
What were the first generations of computers powered by?
vacuum tubes
What is the Size and speed of vacuum tubes computers?
8inchs
What components has the transistor replaced?
Mainly vacuum tubes.
What was the role of the colossus valves?
the first electronic computers were built before the invention of the transistor or integrated circuit chip. They used vacuum tubes for the processing and temporary memory. In Britain those tubes were called valves.
