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.

How many transistors in a modern laptop?
A modern micro processor has atleast 100 million transistors.
Who made the greatest contribution to computing?
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?
What major effect did the transistor have on technology?
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-
What are the Conclusion of five generations of computers?
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.
5 sentences about you learn to use computers and use computers to learn?
1. You can use computers to learn new things.
Is First generation computers did not use microprocessors true?
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.
What did the second generation computers use to make them function?
discrete transistors
Why were the vacuum tubes used instead of transistors in early computers?
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.
Why do you study microprocessors in ece?
To use them in Embedded controllers, in traffic lights control and mainly as heart of computers.
Where do you use computers in todays world?
Where there's information to manage and machines to control.
Do todays computers use vacuum tubes?
No, unless you are still using a CRT monitor.
How many transistors in a modern laptop?
A modern micro processor has atleast 100 million transistors.
What do most computers use as their central processing unit?
Microprocessors. Nearly all of today's laptops and computers have a microprocessor being used as their CPU (central processing unit)
Why do digital computers use binary numbers for their operation?
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.
Why do computers use base 2?
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.
What are transistors used for?
Transistors have two basic functions: # an electrically controlled electric switch # an electrically controlled "proportional valve" which can alter currents and voltages, or can amplify electric signals. Transistors can also be configured as Oscillators which provide an AC signal with constant frequency. Either an amplifier circuit or a switching circuit can be wired as an oscillator. Transistors can be used to form logic gates: And, Or, and Invert. Computers are made from logic gates, so computers can be made entirely from transistors. Transistors are in use in virtually all electronic devices. PC processors are composed of millions of tiny transistors. A transistor radio may have had only 6-10 transistors to enable operation. A late model car may have 10 to 15 computers comprised of thousands of transistors to perform all manner of operations in the vehicle.
What was inside the first modern computers that would get very hot?
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.
