Which Invention Allowed For The Development Of Small Personal Computers?
In 1947, the transistor was invented, which marked the beginning of the movement toward smaller computers and the personal computer. The vacuum tube’s function may now be replicated by a device that is a fraction of the size thanks to the invention of the transistor, which was developed by three scientists working at Bell Labs and earned them Nobel medals.
What invention allows computers to be smaller?
First, there were transistors, and then there were integrated circuits (which can place billions of transistors in a single package).
Which invention made the rise of the personal computer?
Invention of the Personal Computer: Postwar Innovations – ENIAC and other early computers demonstrated to many universities and corporations that the machines were worth the significant investment of money, space, and manpower that was required to operate them.
- This led to the development of the personal computer;
- (For instance, the ENIAC was able to solve the issue of a missile’s trajectory in thirty seconds, but it would have taken a group of human “computers” twelve hours to do it.) During this same time period, advances in technology made it feasible to construct computers that were more streamlined and could fit into smaller spaces;
In 1948, Bell Labs created the transistor, an electronic device that transported and amplified electrical current but was considerably smaller than the unwieldy vacuum tube. The vacuum tube had been the standard electronic component until the transistor came along.
After ten years, researchers at Texas Instruments and Fairchild Semiconductor came up with the idea of an integrated circuit. This was an innovation that combined all of the electrical components of a computer, such as transistors, capacitors, resistors, and diodes, onto a single silicon chip.
The microprocessor, on the other hand, was one of the most important innovations that helped pave the way for the personal computer revolution. Before the development of microprocessors, every single one of a computer’s operations required to be handled by a distinct integrated circuit chip.
(This was one of the reasons why the machines remained as enormous as they were.) The microprocessors were about the size of a thumbnail, and they had capabilities that the integrated-circuit chips did not have.
For example, they were able to run the programs on the computer, recall information, and handle data all by themselves. Scroll to Continue Ted Hoff, an engineer working at Intel at the time, was the creator of the world’s first commercially available microprocessor in 1971.
Where was the personal computer invented?
The Programma 101, the world’s first desktop computer, was shown off to the public for the first time in 1964 at the New York World’s Fair. It was also the first computer to be sold in huge quantities. Pier Giorgio Perotto was the one who came up with the idea, and Olivetti was the company that made it.
Which of the following is personal computer?
Personal computers are also sometimes referred to as microcomputers.
What was the first personal computer called?
From home computers for hobbies to Apple products – When large-scale integration made it possible to construct a sufficiently powerful microprocessor on a single semiconductor chip in the 1970s, it became possible for the first time for companies to produce computers that were small enough to be purchased by individuals for use in their homes and that were inexpensive enough to be used by those individuals.
- The very first personal computer, known as the Altair, was manufactured by a company called MITS;
- 1974 was the year that saw the development of this computer, which was powered by a microprocessor made by Intel Corporation;
In spite of its widespread adoption among computer enthusiasts, the Altair never achieved widespread commercial success. 1977 marked the true beginning of the personal computer industry with the release of three preassembled mass-produced personal computers: the Apple Computer, Inc.
(now Apple Inc.), Apple II, the Tandy Radio Shack TRS-80, and the Commodore Business Machines Personal Electronic Transactor. All three of these personal computers were manufactured by Apple Computer, Inc.
(now Apple Inc.) (PET). These machines were equipped with eight-bit microprocessors, which are able to process information in groups of eight bits, also known as binary digits, at a time. Additionally, these machines had a memory capacity that was rather restricted, meaning that they could only address a certain amount of data that was stored in memory storage.
- However, due to the fact that personal computers were significantly more affordable than mainframe computers, which are larger computers that are typically utilized by large businesses, industries, and government organizations, personal computers were able to be purchased by individuals, small and medium-sized businesses, as well as primary and secondary schools;
The TRS-80 was the most popular model among these computers at the time. The TRS-80 microcomputer was equipped with a memory capacity of four kilobytes, a Z80 CPU, the BASIC programming language, and cassettes for the storing of data. The option to type in lowercase letters was left out of the machine during production so that expenses might be reduced.
- The machine was successful enough to persuade the company to introduce a more powerful computer two years later, the TRS-80 Model II, which could reasonably be marketed as a small-business computer;
- This success can be attributed to Tandy’s chain of Radio Shack stores as well as the breakthrough price of $399, which includes fully assembled and tested components;

What early inventions made computers smaller more energy efficient and faster?
In 1965, Gordon Moore proposed what is now known as Moore’s Law, which states that the number of transistors that may be found on a microchip will nearly double every two years. This phenomena, often known as Moore’s Law, postulates that, as time passes, advancements in computing will become noticeably more rapid, more compact, and more effective.
How small can we make computers?
IBM has announced a new computer chip that is 7 nanometers in size. Producing a prototype chip with transistors that are 7 nanometers wide, which is approximately 1/10,000th the width of a human hair, was one of the challenges that IBM had to solve. The currently available transistors are twice as large as the tiniest ones.
What is the fastest personal computer?
The Personal Computer Revolution: Crash Course Computer Science #25
A 64-Core TR 3990X Is Faster Than A 16-Core 5950X – In 2021, the world’s fastest central processing unit (CPU) is expected to be AMD’s 64-core, 128-thread Ryzen ThreadRipper 3990X desktop processor for personal computers. The central processing unit (CPU) has a base rate of 2.
- 9 GHz and a maximum boost clock of 4;
- 3 GHz, which allows for efficient multitasking and quick load times;
- It is the most recent central processing unit (CPU) produced by AMD and the first HEDT (High-End Desktop) processor ever produced;
It was developed specifically for high-end 3D rendering as well as for video pros and visual effects. The 64-core TR 3990X is designed to work most effectively with motherboards that include sTRX4 TRX40 sockets and PCle 4. 0 communication capabilities. In addition, the TR 3990X is equipped with multichannel RAM and SATA connections, as well as compatibility for NVMe RAID technologies and several GPU technologies.
- Because it has an AMD “Zen” core design, improved energy efficiency, more energy capacity, additional cores, and higher clock rates, the processor is significantly quicker than most other CPUs;
- Its lightning-fast speed is made possible by its 64 cores and 128 threads, as well as by its massive GPU and quad-channel DDR4 memory channels;
When it comes to certain operations, the AMD Ryzen 9 5950X 3. 4 GHz core is another powerful CPU that is available on the market. However, it is a little bit slower than a 64-core TR 3990X CPU. The Ryzen 9 5950X has 16 cores and 32 threads, which makes it ideal for multitasking, especially when it comes to resource-intensive apps.
The vast majority of AMD processors, including this 16-core 5950X CPU, feature PCle Gen 4 technology and 3200 MHz DDR4 RAM. In addition to that, it has a Thermal Design Power (TDP) of 105 watts and does not include a cooling unit.
In addition, the Ryzen 9 5950X lacks a GPU, which requires customers to initially install an external graphics card into their motherboards before they can utilize the processor. As a result of its superior features and incorporation of AMD’s most recent advancements, the Ryzen Threadripper 3990X is regarded as having a higher processing speed than AMD’s Ryzen 9 5950X desktop PC CPU.
- Nevertheless, this does not imply that the Ryzen 9 5950X is a slower CPU or one that is less reliable in any way;
- The CPU could be slower overall, but it might be more efficient in some applications or when carrying out particular tasks in comparison to the Ryzen TR 3990X;
The Ryzen TR 3990X, which features 64 cores and 128 threads, is widely regarded as the most powerful central processing unit (CPU) currently available on the market.
What invention made computers smaller and more affordable?
According to the findings of researchers working at the Center for Heterogeneous Integration and Performance Scaling (CHIPS) at the University of California, Los Angeles (UCLA), computers that are powered by standard integrated circuit chips have reached their limitations and require a redesign.
- They want to fundamentally alter the components of electronics in order to make it possible for new generations of systems that are quicker, cheaper, smaller, and more powerful, in addition to being flexible and implantable;
Since 1965, the number of transistors that can fit on a single computer chip has about quadrupled every two years. This is due to the fact that transistors have become exponentially smaller. This doubling, which has been given the name Moore’s Law, has resulted in computers that are more powerful, smaller in size, and less expensive overall.
This doubling, however, is expected to come to a halt when transistors reach the atomic scale that is the smallest that the qualities of the materials and the laws of physics will allow. The arrangement of chips on a circuit board has not altered much despite the fact that computer processors have become far more powerful and are now packed with billions of transistors.
Each chip is separated from its neighbors by a decent distance, and there are printed traces that can be seen connecting them. This arrangement not only takes up a large amount of space that could be used for anything else, but it also makes things go more slowly.
“There has been no reduction in the amount of energy required for communication between chips; on the contrary, it has increased. It’s kind of like trying to keep an old, dilapidated road system open when a city is expanding and getting busier “remarked Professor Subramanian Iyer of the Electrical and Computer Engineering Department at UCLA, who also serves as Director of CHIPS.
Silicon wafers are currently being used in place of the typical circuit boards that Iyer and his coworkers have been using. Due to the fact that transistors are constructed of silicon, the researchers have the ability to precisely align individual integrated circuits, also known as dies, onto each wafer.
- Because of this, it is possible for all of these dies to perform their functions as if they were part of a single enormous chip that is the size of the wafer, which may be as huge as 70,000 square millimeters in area — almost the same size as a large dinner plate;
In comparison, the biggest chips that are manufactured now are around 100 times smaller, thus their surface area is just about 700 millimeters squared. Creating today’s single big chips, known as SoCs, is a costly endeavor since it requires the concurrent fabrication of several dies using the same manufacturing method.
In the event that you require both memory and CPUs, for instance, you would have to reduce the performance of either one, or maybe even both, of them in order to manufacture them using a single process.
The dies used in the platforms that are now being created at UCLA can come from a variety of different places, and they can be combined with dies from other platforms. Iyer said that by doing the manufacturing of the memory and CPU dies in separate processes, there would be no impact on the overall performance of either component.
In addition to this, the dies are able to be packed in much closer proximity to one another than traditional chips are, and the silicon wires that connect them can have a width of only a few nanometers.
They have given it the moniker Silicon Interconnect Fabric (Si-IF), and a square of this material is far more compact than its matching printed circuit board equivalent in terms of its functionality. Si-IF provides additional benefits in comparison to printed circuit boards, including a lower overall weight, the capability to create bigger networks in a smaller area, and the ability to be made entirely flexible through the utilization of a technique that the team has dubbed Flextrate.
According to the researchers, these characteristics make Si-IF and Flextrate particularly well-suited for use in medical devices. They are working along with medical professionals and engineers specializing in biomedicine to create applications for the technology.
Selvan Joseph, a researcher in the departments of physiology and neuroscience at California State University, Los Angeles, is utilizing the Flextrate platform in order to design sensors that can track the physical movements and muscle activity of patients who suffer from movement disorders or who are recovering from spinal cord injuries.
Because of Flextrate, he is able to conceal these sensors within a tiny, flexible patch that patients may wear on their skin without drawing attention to themselves. According to Joseph, “We are able to send this gadget home with our patients and then gather data remotely in real time as they go about their day-to-day activities.” The CHIPS group is also focused on developing methods to enhance the power of supercomputers and other devices that use artificial intelligence.
Inference engines are the driving force underlying a significant portion of the “smart” technology that we use on a daily basis. An inference engine is a piece of software that takes in data and draws inferences based on that data. Inference engines are crucial to the operation of search engines, virtual assistants such as Apple’s Siri and Amazon’s Alexa, and self-driving automobiles.
- However, the pace of these is restricted due to the fact that in order for the device to draw an inference, information must be sent between the memory and processing centers of the device;
- Iyer and his coworkers have developed what is known as a charge trap transistor (CTT);
This device integrates memory and processing centers in such a way that the need for continuous back-and-forth is eliminated, which results in time and energy savings. According to Iyer, “We are able to make inferences in a CTT that is one hundred times more efficient than the most efficient inference engine that is currently available.” “We have successfully shown this on a smaller scale, and we are now beginning the process of adding on more bells and whistles.” Iyer believes that the days of technological progress being driven by ever-smaller transistors are behind us and that we have reached a plateau.
The question that has to be asked is how technological advancement will proceed in the absence of advancements in transistors. The transition to new kinds of devices, such as those that employ Si-IF and CTTs, is one approach that is plausible, but it requires the participation of firms that specialize in technology.
CHIPS has created a consortium consisting of industry leaders in order to verify and influence the center’s future path in part because of this reason. Source
What component made computers smaller and affordable accessible?
The Third Generation – The period of transistors was brief because, in 1964, integrated circuits became the next big thing in improving semiconductor technology. This caused the era of transistors to come to an end. Integrated circuits made it possible to install transistors on silicon chips that were of a smaller size. And of course, the improved technology increased the speed and efficiency, as well as being much more compact and less expensive to operate.
Additionally, the computers were created to be more easily available and more reasonably priced for a larger population. Keyboards and displays eventually took the place of punched cards and printouts, and the first operating system was developed to make it possible for numerous programs to run simultaneously on a single computer.
As time goes on and computing technology advances, you can almost certainly observe the beginnings of the contemporary computer taking form. The speed of computers increased but at the same time they required less energy and money to operate and became more cheap for the average person to purchase.
What component made computers smaller affordable and accessible?
Especially Important Considerations The prospect of an eternally empowered and linked future carries with it both difficulties and opportunities. For more than half a century, developments in computing have been propelled by the shrinking of transistors.
However, in the near future, engineers and scientists will need to find new ways to make computers more competent. Applications and software could be able to assist enhance the speed and efficiency of computers, as opposed to physically doing activities.
Computing on the cloud, wireless communication, the Internet of Things (IoT), and even quantum physics all have the potential to play a part in the development of new computer technology in the future. In spite of the mounting worries over privacy and security, the benefits of ever-smarter computer technology have the potential to help us remain healthier, safer, and more productive in the long run.
How did microchips change computers?
The invention of the microchip made it possible to reduce the size of hundreds of different devices, including computers, controllers, and communication devices, amongst others. Since 1971, whole central processing units of computers, often known as CPUs, have been housed on microchips.
