Why is mainframe used in programs?
A mainframe is just a physically very large computer, it is programmed no differently than minicomputers and microcomputers. All computers were mainframe computers before the early 1960s (because of the size of vacuum tubes and the first discrete transistors), when discrete transistors and then integrated circuits made possible the smaller minicomputers. In 1971 Intel introduced the microprocessor integrated circuit making the even smaller microcomputers possible.
Why was the invention of the integrated circuit an important milestone?
Integrated circuits are etched onto a silicon chip. All the elements of a complete circuit can be included on a small slice of silicon, including transistors, resistors, capacitors and diodes. It takes several stages of a photographic and chemical process, to build up the design in a clean room to create a chip. After the initial design, they can be mass produced at minimum material cost. The chip is encapsulated in a small plastic box and legs sticking out, enabling it to be soldered onto a board with other chips and discrete components. They are important to computers, as the miniturisation and complexity allows computers to be buit into a small enclosure at a reasonable price.
What two technologies were used in computers before intergrated ciruits were used?
I would say vacuum tubes and punch cards. May not be a textbook answer, but those are the two that came to mind.
What were used before transistors?
If the integrated circuit in some kind of device has 5,000 transistors on it, then before integrated circuits were available, the same function might have been performed by 100 individual transistors. And before transistors were available, the same function might have been performed by 30 vacuum tubes, a fan and air system to keep them cool, and a large power system to operate the tubes and the cooler.
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.
Do vacuum tubes did it lead to an increase or decrease in size?
Vacuum tubes vary from thumb size to larger than most people. Integrated circuits or ICs' are the size of you little finger nail. There was nothing worth remembering before vacuum tubes.
What was the role of the colossus valves?

History of computer Before 1st generation of computers?
Electro-Mechanical Computers were used before first generation of computers.
What is an ic how it helps in reducing the size of computers?
IC stands for integrated circuits. They help to reduce the size of the computer because it is simply a small chip that is embedded with all the information needed. Because the chip is so small, the sizes of computers can be reduced.
Can you describe human successes in five technologies and human failures in five different technologies?
Many technologies can fall into both the human failures category and the human success category. A good example of this would be the light bulb, because Thomas Edison had to fail a large number of times before he succeeded. Human's failures in technologies would be nuclear power, weaponry, medicine, thermodynamics, and genetic engineering. We eventually succeed in all of the categories, but we first had to fail. Man's success in technologies would be wind and solar energy, computers, automobiles, telephones, and portable music players. These technologies were also trial and error before they were a success, but they are always being changed and becoming more advanced, now that they work.
Computer built before the first generation of computers were?
No computers.
