5G vs. 4G Connectivity
5G uses utilises much higher radio frequencies of 28 ghz.
4G uses lower reading frequencies of 700 mhz to 2500 mhz.
5G transfer more data over the air at faster speeds.
4G speed is lesser with less data transfer.
5G has lower latency i.e the delay before a transfer of data begins following an instruction. Latency for 5G is pred
What is Quantum Supremacy?
It describes the point where quantum computers can do things that classical computers cannot.
Superposition and entanglement are what give quantum computers the ability to process so much more information so much faster.
Differences between a standard computer and a quantum computer:
A classical computer performs calculations using bits that is 0 (representing off )and 1 (representing on).
It uses transistors to

Mobile Phone Technologies
The development of 1G mobile phones took place in the late 1970s.
The 1G mobile devices sent only the “analogue voice information” via amplitude modulation (AM), which varies the amplitude of the carrier signal, and frequency modulation (FM), which changes the Frequency of the career signal.
In electronics, the analog signal devices were followed by Analog to Digital convertors.
The most important 1G system were
India's Rising Supercomputing Capabilities
India is fast emerging as a leader in high-power computing with the National Super Computing Mission (NSM) boosting it to meet the increased computational demands of academia, researchers, MSMEs, and startups in areas like oil exploration, flood prediction as well as genomics and drug discovery.
Completion in of Phase II of NSM in September 2021 will take the country’s computing power to 16 Petaflops (PF).

METADATA AND FACEBOOK TO METAVERSE
What is Metadata?
Metadata Meaning: Meta-data is "data that provides information about other data", but not the content of the data, such as the text of a message or the image itself. There are many distinct types of meta-data, including:
Descriptive meta data — the descriptive information about a resource. It is used for discovery and identification. It includes elements such as title, abstract, author,
Bitcoin, Blockchain Technology: A Detailed Overview
Context: This topic is important for UPSE Prelims and GS Paper 3.
El Salvador, a small coastal country in Central America, became the first in the world to make Bitcoin, a digital currency, legal. Let’s understand all about it in detail.
What Is Bitcoin?
It is the first decentralized digital currency (Cryptocurrency) that allows peer-to-peer transfers without any intermediaries such as banks, governments, agen
4G Vs. 5G
Context: This topic is important for UPSE GS Paper 3 And Prelims.
"G" stands for "GENERATION". While connected to the internet, the speed of the connection depends upon the signal strength that is shown in abbreviations like 2G, 3G, 4G, 5G, etc. on any mobile device.
Each generation of wireless broadband is defined as a set of telephone network standards that describe the technical implementation of the system.
Context: Metaverse is important topic for UPSE GS Paper3
Its commodification in the hands of one corporation could be detrimental to the Web 3.0 decentralisation movement.
The race between technology companies to build the ‘metaverse’ has officially started. On October 28, 2021, Facebook Inc. announced that it was restructuring and assuming the corporate name, Meta Platforms Inc., announcing that ‘from now on, we’re going to be metaverse-first, not Faceb
