Now is the age of connection. Those whose connections are powerful will win (they can even cross piled notes of two thousand together)! Social media is also about connections. But in the tech world we don't pay much attention to the various , actual , physical cables that make such connections possible.

The world is going wireless , but we are still stuck with many types of cables. The cables discussed here are more useful for special purposes than the original cables , because of the features on their ends. Similarly , the port where this cable is connected also has a specific role. For now , let's learn a little about some of the cables we see every day.

3.5mm Jack

We mostly use this type of cable , called a 3.5 mm (different sizes) jack, to connect wired headphones to smartphones for audio , but also for video-audio output in digital cameras , camcorders, or digital players. type of cable used. A headphone mic can also be used if there is an additional connector ring on the end of such a cable for audio. Now, however, major companies, including Apple, have shifted to Bluetooth headphones and smartphones are no longer providing jack slots for the use of such cables.

USB (Universal Serial Bus)

The most useful cable in the digital age! Almost every device that can be connected to a computer - keyboard , mouse , headset , external hard drive , printer , scanner, etc. - can be connected with this type of USB cable. As time has changed , there have been versions of USB that can transmit data at higher and higher speeds. Currently the USB 3 version is most in circulation , along with which the USB 4 version has also arrived. In addition to standard USB, mini and micro USB are commonly used for phones , digital cameras, etc. However, Type-C USB is now the rage!

Ethernet

The entire internet can be said to run on these cables , at our end of course! In the home or office , such cables are used to connect the internet cable from the internet service provider company to the modem and computer beyond the router. These cables are of three types according to data speed , Currently , the most popular type is Cat 5e or 6 , followed by even higher speed Cat 8 , which transmits data at 40 Gbps over a length of 100 meters . These latest cables are also waterproof , although the latest cables are not required for normal use.

FireWire

Almost lost cables now! Developed by Apple , IBM and Sony, this cable was once seen as the only cable the entire tech industry needed , superior to USB , but Apple's lack of money or hunger for money killed it. The company decided to charge a license fee per port of FireWire to reduce its financial burden. As a result of this decision, Intel stopped supporting this cable and turned to USB instead. With that, the world of cable changed!

SATA (Serial Advanced Technology Attachment)

These cables are the ones that are usually invisible to us , doing their work out of sight like a foundation stone. Previously in the computer's CPU to connect the storage device to the motherboard IDE (Integrated Drive Electronics) Cables used to be used (pictured above) , now SATA cables are used , which are faster. Similarly , eSATA (External Serial Advanced Technology Attachment) is used to connect an external hard drive or optical drive .

VGA (Video Graphics Array)

Cables in use for four decades! This cable has been used for years to connect a computer's CPU to a monitor. IBM Company started using it for PC desktop. These cables make analog type connections and are waning in popularity in today's age of digital data connectivity. The socket of this cable has 5 pins in 3 rows , these three are used for Red , Green and Blue (RGB!) signals for the display in the Rono monitor.

DVI (Digital Visual Interface)

Old-fashioned cable! As time went from analog to digital, DVI cables became popular in place of VGA. It is used to connect an LCD monitor or projector to a computer. However , if older CRT or LCD displays still have VGA connectivity, a DVI-A cable can transmit analog signals. DVI-D (for digital) to DVI-I (for both analog-digital) are also popular. There are also cables that convert VGA-DVI to AAC as needed.

HDMI (High Definition Multimedia Interface)

Cables for new age high quality displays! This is not really a type of cable but a new technology. This cable only transmits digital signals. It transmits video-audio signals simultaneously , that too with crystal-clear images and multi-channel audio support. Earlier TVs had cables with three colored pins to connect other equipment , but newer TVs require an HDMI cable to connect anything. It is used in new computers/laptops , HDTVs , projectors, etc.

Darkness will be the enemy of Chandrayaan! How the lander and rover on the moon will work at night, this time is the most challenging

Image
One day on the Moon is equal to 14 days on Earth. In this regard, rover Pragyan and lander Vikram, which reached the lunar surface by Chandrayaan 3 on August 23, have only a few days left. Although ISRO scientists have not ruled out the possibility of Pragyan and Vikram resuming operations, it has become important for the rover to acquire data quickly. Isro's important phase begins on the moon ISRO has said that Chandrayaan 3 is going to do three major tasks on the moon. It includes soft landing on the lunar surface, exploration of the lunar surface and some experiments on the surface. So far ISRO has been successful in the first two, but the experimental phase is still ongoing. Vikram and Pragyan carry the payload through which the data is being collected. An attempt to cover a distance of 300 to 400 meters on the moon SAC director Nilesh M Desai says that scientists are trying to cover the maximum distance to the South Pole.

Four days later, the astronauts covered a distance of 3 lakh km and reached the moon. The Apollo 11 mission aroused the curiosity of astronauts and space science enthusiasts. It entered lunar orbit on July 16. It was then decided to land at a place about 50 km southwest of the moon's scatter Sabin dish. The Ranger-2 and Surveyor-2 surveys conducted a comparative study of the area in which the area was found to be flat for landings compared to others. A portion of Apollo 11 was released from the Eagle Command module Scholambias. Neil sent a message to the control center in Houston that they were safe, albeit a short distance from the target. The spacecraft landed northeast of the 50-meter-diameter Swift Cretaceous with 6 seconds of fuel remaining. After the first commander Neil Armstrong landed, ...

For the first time in the history of medical science, an HIV patient recovered automatically

Image
New York, September 1, 2020, Tuesday There is no cure for HIV / AIDS in the world. Some medications can prolong life but do not destroy the virus that weakens the immune system. However, scientists and doctors are surprised that an HIV patient recovers without any treatment. There have been two previous cases in which the virus did not re-enter the body after bone marrow transfer, but it is the first time that the HIV virus has exited without any treatment, perhaps because the immune system has destroyed it. According to information published in the journal Nature, the doctors examined 120 million cells in the body. The AIDS patient was then named ECTU. The fact that the body was free of the HIV virus meant that the body had eliminated it. In addition, 100 million cells from another AIDS patient were examined, in which doctors found only one virus to be active. However, the active virus also appeared to be genetically inactive. This also meant that the genetics of both AIDS patient...

BharatOS for the people of India, of the people of India, by the people of India!

Image
For the security of India's sensitive data, a special type of smartphone operating system was developed The Android operating system (OS) has long dominated the smartphone market. In second place is Apple's operating system. In the case of Android, the phone manufacturing company can make its own changes to the original Android software , but ultimately the ' new ' OS also remains under the control of various private companies. In this matter there is a big problem of security of user's data. Keeping this in mind, the Indian government has been in the forefront of developing its own operating system for a long time. Now there is news that India has become self-sufficient in this regard - a company incubated at IIT Madras has developed such an indigenous mobile operating system. Apparently it has been named ' BharatOS ' . Of course , it is not clear whether he is fully Indian or not. ' BharatOS ' has been developed for computer...
