Yes, today's computers use transistors and microprocessors. Smaller transistors subset the amount of RAM that is local to the CPU at any given moment.
A modern micro processor has atleast 100 million transistors.
Correction, this is WHAT was the greatest contribution, sorry!There could be many different answers to this question... First generation computers used Vacuum Tubes, these computers were very slow and could only handle one process at a time, they were also VERY large and expensive. Vacuum tubes were replaced by Transistors, which were smaller, cheaper, and faster, however transistors produced a lot of heat (these computers used punch cards and ran off of assembly language [Binary Code]). Third generation computers marked the use of Integrated Circuits, there were basically small transistors placed on silicone chips, making computers even smaller and efficient (in this generation we saw the first User Interfaces and use of mouses [mice??] and keyboards). We are currently in the fourth generation of computers, this generation is marked by the placement of thousands of integrated circus onto a silicone chip, making up a Microprocessor. The fifth generation is currently in development and will be based off the principals of Artificial Intelligence (computers with brains!! kind-of except not really..) and Natural Language Recondition (you talk to the computer and it knows what you're saying).So really its your call, Vacuum Tubes, Transistors, Integrated Circuits, or Microprocessors?
The transistor gave the technology world a huge boost, which is what originally started up modern computers today which use 32nanometer transistors that switch to 1 and to 0. Transistors have created the world we live in today that includes much more technologically advanced computers that get twice as fast each year. -Room for improvement-
First Generation (1940-1956) Everything started with vacuum tubes. These were widely used in the first computer systems for circuitry, while magnetic drums were used for memory. Second Generation (1956-1963) Next, there was the introduction of transistors, which came in to replace vacuum tubes. ... Third Generation (1964-1971) Third-generation computers were where we saw the introduction of integrated circuits (IC), which are still in use today. Fourth Generation (1971-2010) In the fourth generation of computers, the invention of the microprocessor (commonly known as CPU) helped to get computers to the desk and, later, lap-size that we ... Fifth Generation (Present Day) Although we are still using technology from the fourth generation of information technology, we are now going into a new age: the fifth generation.
1. You can use computers to learn new things.
I believe its true. Computers need a processor. The early processors were made using separate components, logic gate ICs and transistors. They became MICROprocessors when all the logic gates and components were combined onto a single silicone chip, as a dedicated processor.
discrete transistors
Early transistors were much slower and far more expensive than vacuum tubes. Also computers built before 1948 there were no transistors to use at all.
The fourth generation of computers, which emerged in the late 1970s and continues to the present, is characterized by the use of solid-state components, particularly integrated circuits (ICs) and microprocessors. This generation marked a significant advancement in technology, leading to smaller, faster, and more efficient computers compared to previous generations that relied on vacuum tubes and transistors. The development of microprocessors in this era paved the way for personal computing and the proliferation of computers in everyday life.
To use them in Embedded controllers, in traffic lights control and mainly as heart of computers.
Where there's information to manage and machines to control.
No, unless you are still using a CRT monitor.
Microprocessors. Nearly all of today's laptops and computers have a microprocessor being used as their CPU (central processing unit)
A modern micro processor has atleast 100 million transistors.
Digital computers use binary numbers because that is easier for them, and the easiest way for humans to represent what goes on inside of computers. Computers contain millions of transistors inside the various ICs in the computer. Transistors can generally be on or off. Sure, it is possible for transistors to have a range, but then, in this case, it wouldn't be digital. So since the transistors are used as on-off switches, it is easiest to represent them as binary digits, since they can either be on or off.
Computers use base 2 because a transistor only has two states, on and off and these are best represented by a 0 and a 1. Transistors are the building blocks of a computer's ICs.
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.
