- The earliest electronic digital computers used hot cathode vacuum tubes. The cathodes of these tubes glowed red hot.
- The second generation electronic digital computers used transistors. These ran much much cooler than hot cathode vacuum tubes, but could still get warm. Even though individual transistors normally did not get hot, if the complete computer was not equipped with a cooling system it could accumulate enough heat to damage itself.
- The third generation electronic digital computers used bipolar integrated circuits. Due to the number of transistors in these integrated circuits, some types got hot enough to burn your skin if you touched them.
- Modern fourth generation electronic digital computers use field effect transistor integrated circuits and microprocessors. While these generally operate cooler than bipolar integrated circuits, often the microprocessors and a few other high speed integrated circuits can still get hot enough to burn your skin if you touched them.
What else can I help you with?
What is the name of first computer which is store data?
all computers store data. if they did not, they would have nothing to compute.
Why were computer improvements made?
Because back then the computers were too slow and a lot of bugs and glitches were found inside each OS that was back-then created and being worked on. If we didn't have improvements made to our OS', it would be difficult with work with modern-society as we basically run on technology with hopes of improving every step of the way.
Were microcomputers a part of the first generation of computers?
No, the earliest computers (from the 1940s to the mid 1960s) were all mainframe computers. The first microcomputers were made in the early 1970s. However many of the earliest computers were much slower and had far less memory than the earliest microcomputers!
What items would be used for centralized storage example notebok computers PDA's microcomputers or mainframe computers?
notebook computers
Technology in Vietnam vs Iraq?
Generally computers (GPS) and safety first (Iraq) verses reading a map and mission first (Vietnam). The list would be long for either.
What part of many modern computers has the word 'crop' inside its name?
Mi-CROP-rocessor, the king of the modern computer. Without it, the computer would not know what to do, when to do it, or what it is.
What was inside the first computers that would get very hot?
The heaters of the vacuum tubes glowed red hot to make the cathodes emit electrons.
Do you need computers in high school?
Computers are a tremendously important tool in modern society, so for schools or colleges NOT to have computers would be folly in the extreme.
What would happen to an Airbus if all computers failed?
It would undoubtedly crash. As would any modern aircraft.
What are the examples of modern technology and traditional technology?
Modern technology would be things that we have today such as smart phones, tablets, gaming systems, and computers. Traditional technology would be things such as handicrafts that were made before things such as computers were invented.
Why were input devices invented?
Without input devices, the only way to reprogram computers would be to pull them apart and rewire them. In modern computers with integrated circuits that would be impossible. Input devices, such as keyboards, make it much easier to reprogram computers with new instructions and/or data.
How many transistors in a modern laptop?
A modern micro processor has atleast 100 million transistors.
What impact have computers had on gaming?
Well, most modern games are available on computers. And all kind of game programming (even for consoles like ps3 and xbox) is done on computers. If it wasn't for computers we would sit around the table in the evenings and play cards with our grandmothers :)
How much money do you spend for keeping computers on for a full day?
Modern home computers are usually very efficient and use little power but it would depend on the make, model and monitor.
How is the first home computer different from the computers that are in our homes now?
The first "home computers" were more hobbyist computers than home computers. You really had to be more interested in them as a hobby that was going to consume much of your time rather than as a tool that was going to be useful. Many of them came in kits with inadequate instructions that you would have to assemble using a soldering iron, hopefully you made no mistakes! The first one I saw advertised in an electronics magazine was called the Mark-8 using the Intel 8008 microprocessor. You could order a package including the schematics, PC board artwork, and parts list (you had to etch the boards yourself and buy the parts on your own) or you could order a set of already etched boards (you still had to buy the parts on your own). The Mark-8 had no I/O devices, so you would have to improvise these!
What are the 1st generation computers?
The UNIVAC and ENIAC computers are examples of first-generation computing devices. Computers employing vacuum tubes are known as first-generation computers. THESE WOULD OCCUPY A 1800 SQUARE FEET. IT WOULD CONTAIN 18000 VACCUM TUBES AND CONSUME A LARGE POWER
Why did jeffery make computers?
well think about it why would you invent a computer in the first place
