Why was the first computer not put at home?

The first computers appeared in the forties of the last century. They covered a huge area! One of the earliest computers, ENIAC, created in 1944, occupied 165 square meters, like seven small modern apartments! He weighed 27 tons. This giant worked on vacuum lamps, and the burned-out ones had to be replaced 2-3 times a week.

Unlike modern computers, calculations on it were made in the decimal system. Reprogramming was very difficult. Sometimes it happened that this process took several days, and then the task was solved in a few minutes. It is clear that this computer could only work in scientific institutions, and it was used for complex mathematical and statistical calculations. And still it turned out faster than manually.

The first industrially produced personal computers appeared in the second half of the 1970s. Soon mass computerization of the population began.

What are microbes?

For thousands of years of its existence, man had no idea what causes his diseases. Primitive people had their own "explanation" for this - they believed that the disease was caused by evil spirits living inside their victim.

It wasn't until 1865 that science proved that microbes are the cause of disease. Louis Pasteur was the first to put forward the theory that microbes are the cause of diseases. And today we know that microbes are the most dangerous enemies of man. They are the smallest single-celled microorganisms visible only under a microscope. Some of them are so small that they are practically invisible!

Microbes, or microorganisms, may be of animal or plant origin. Microbes of animal origin are called "irotozoa", vegetable - "bacteria". The third group of microbes is called "filterable viruses", which means that they are so small that they can pass through the finest filters that trap larger organisms.

One type of microbe causes only one disease. For example, the microbes that cause scarlet fever will not lead to malaria or other diseases. And scarlet fever is caused by only one type of microbe. However, there are many microbes that are representatives of the same type as pathogens that benefit a person.

In a disease caused by microbes, if a person does not die, his body sooner or later destroys these microbes. In some diseases, such as scarlet fever, measles, or mumps, a person does not get sick again. This ability of the body to resist reinfection is called "active immunity". Some animals are "naturally immune" which means they do not suffer from diseases that other animals do. Vaccinations and antitoxins make a person immune to certain microbes.

Filterable viruses cause diseases such as measles, rabies, chickenpox, infantile paralysis, the common flu, and the common cold. Scientists still have a lot to learn about these tiny, almost invisible microorganisms.

Artificial leather for touch emulation 15.04.2024

In a modern technology world where distance is becoming increasingly commonplace, maintaining connection and a sense of closeness is important. Recent developments in artificial skin by German scientists from Saarland University represent a new era in virtual interactions. German researchers from Saarland University have developed ultra-thin films that can transmit the sensation of touch over a distance. This cutting-edge technology provides new opportunities for virtual communication, especially for those who find themselves far from their loved ones. The ultra-thin films developed by the researchers, just 50 micrometers thick, can be integrated into textiles and worn like a second skin. These films act as sensors that recognize tactile signals from mom or dad, and as actuators that transmit these movements to the baby. Parents' touch to the fabric activates sensors that react to pressure and deform the ultra-thin film. This ... >>

The attractiveness of caring men 14.04.2024

The stereotype that women prefer "bad boys" has long been widespread. However, recent research conducted by British scientists from Monash University offers a new perspective on this issue. They looked at how women responded to men's emotional responsibility and willingness to help others. The study's findings could change our understanding of what makes men attractive to women. A study conducted by scientists from Monash University leads to new findings about men's attractiveness to women. In the experiment, women were shown photographs of men with brief stories about their behavior in various situations, including their reaction to an encounter with a homeless person. Some of the men ignored the homeless man, while others helped him, such as buying him food. A study found that men who showed empathy and kindness were more attractive to women compared to men who showed empathy and kindness. ... >>

24-pin ATX connector will be replaced by 10-pin 31.01.2020

The PC market, of course, is more inert than the smartphone market, but even here everything is changing, and in recent years it has been very active. It is enough to take the processor segment, where less than three years have passed since the release of the first Ryzen CPUs, and there have been more changes than in the previous ten.

But among all that is changing, there are a number of features that remain unchanged for years and even decades. In particular, a large 24-pin connector, through which power is supplied from the block to the motherboard, is known even to those who are very far from the PC world - it’s enough just that a person sometimes opens the case to clean it from dust.

This connector belongs to the ATX standard, which was adopted 25 years ago and began to become active in the market about 20 years ago. And soon he will finally retire.

According to the source, Intel intends to introduce a new connector - ATX12VO this year. It will change not only externally, but also electrically. As you know, now the main components of the PC are mainly powered by 12 V, however, the 24-pin connector also supplies other lines (3,3 V and 5 V) to the motherboard. In the case of ATX12VO, everything will change - all lines will be 12-volt, and the motherboard itself will deal with the conversion. In addition, the connector will become 10-pin, which will make it much more compact.

Most likely, at first only PC manufacturers will completely switch to the ATX12VO standard, and components for self-assembly will continue to use the old connector for some time. A full transition to the new standard will obviously take more than one year.
