It is organised by the Insafe/INHOPE network of awareness centres, that is spread across 30 countries and is funded by the Connecting Europe Facility program (CEF) of the EU. It aims to increase awareness about emerging online issues, such as cyberbullying, and chooses a topic reflecting current concerns


NetWire, which first surfaced in 2012, is a well-known malware. It is a remote access Trojan which gives control of the infected system to an attacker. Such malware can log keystrokes and compromise passwords. Viruses                          A computer virus is a type of malware that propagates by inserting a copy of itself into and becoming part

5G vs. 4G Connectivity

5G 4G 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 predicted to be below 10 milliseconds, a


QUANTUM SUPREMACY: 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


ETHEREUM 2.0 The Ethereum is a crypto currency. Recently, it was launched in a faster, cheaper and more environmentally friendly platform, as the upgraded version called ‘Ethereum 2.0’. What is Ethereum? Ethereum is a decentralised and open source blockchain platform, which is a growing list of cryptographic blocks. It is the world’s second-largest cryptocurrency by market capitalization, only after bitcoin. It is also the world’s most actively us

It has secured rank 63 in TOP 500 most powerful non-distributed computer system list in the world. Features : Param Siddhi was jointly developed by Ministry of Electronics and Information Technology and Department of Science and Technology. The supercomputer has a speed of 5.267 petaflops. It has now

Mobile Phone Technologies

Mobile Phone Technologies 1G Technology The development of 1G mobile phones took place in 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 Advanced Mo

India's Rising Supercomputing Capabilities

India is fast emerging a leader in high power computing with the National Super Computing Mission (NSM) boosting it to meet the increasing 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). Infrastructure planned in NSM Phase I has already been installed and much of P


Context: This topic is important for UPSC GS Paper 3. 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, abst

Bitcoin, Blockchain Technology: A Detailed overview

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

4G Vs. 5G Context: This topic is important for UPSE GS Paper 3 And Prelims. Background- "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 technological implementation of the system. Brief
