In today’s digital age, much of our personal communication takes place through messaging apps, video calls, and email services. With so much information being exchanged online, the question of privacy becomes important. End-to-end encryption, often referred to as E2EE , is one of the strongest ways to protect digital communication. At its core, it means that data is encrypted on the sender’s device and can only be decrypted on the recipient’s device, ensuring that nobody else, not even the service provider, can read the content in between. The main purpose of this system is to keep conversations private and secure, even as messages travel across different networks and servers. It prevents hackers, internet providers, governments, and even the platform itself from accessing the content of your communication. This is why many widely used services such as Signal, WhatsApp, certain settings in Zoom, and even secure email platforms like ProtonMail have adopted end-to-end encryption. The way...

In many homes today, an inverter has become almost a necessity to keep the lights and fans running during power cuts. While it is a comfort during outages, something I started noticing is that in several households, electronic devices like printers, routers, televisions, and other gadgets tend to develop complaints in their circuit boards more frequently when part of the wiring is connected to an inverter. At first, this looked like just bad luck or poor product quality, but after looking closer and discussing with technicians, it became clear that the root cause lies in the way inverter power behaves. The electricity we normally get from the power grid is a smooth sine wave, but not all inverters supply that kind of clean power. Many cheaper or older models produce a stepped or modified waveform, which is fine for simple devices like lights and fans but not so healthy for sensitive electronics. Gadgets that rely on delicate circuit boards and power supply components can get stressed b...

YouTube Premium has become a familiar name among people who prefer uninterrupted video streaming and music without advertisements. For many in India, it is not just about avoiding ads but also about the convenience of downloading videos, playing content in the background, and enjoying YouTube Music without interruptions. With internet usage growing rapidly in the country, prepaid and monthly subscription models of YouTube Premium are now gaining wide acceptance, especially among those who do not want to commit to long-term plans. The most common option for users in India is the monthly plan that starts at ₹149 per month. This plan is straightforward and allows subscribers to enjoy all the benefits of YouTube Premium, including ad-free videos and music, offline downloads, and background play. Alongside this, prepaid options are also available for those who want to pay in advance without worrying about auto-renewals. A monthly prepaid plan is priced at ₹159, while quarterly and annual pr...

India’s agricultural sector has always been central to the country’s economy and food security. For centuries, farming has relied on traditional knowledge, seasonal rhythms, and local practices. But with rising population, climate challenges, and the need for efficiency, agriculture today demands modern solutions that blend tradition with technology. The Digital Agriculture Mission is one such effort that aims to transform farming into a digitally empowered, data-driven system while keeping the farmer at the center of every initiative. The vision of the Digital Agriculture Mission is to create a comprehensive ecosystem where farmers’ information, land details, crop surveys, soil health data, and government schemes are integrated into a single, transparent digital framework. By using space technology, geospatial mapping, and real-time data collection, the mission seeks to make governance in agriculture smarter, more reliable, and far more accessible to farmers. At the same time, it ensu...

Early phase: Training at Pratiksha Computer Centre began with the Sinclair ZX Spectrum in the mid-1980s, operating with BASIC and audio cassettes (Compact Cassette) as storage media, where students learned BASIC programming and used audio cassettes for saving programs . One of the most famous computers of that era was the Sinclair ZX Spectrum, released in 1982 in the UK and later brought to India by enthusiasts. At that time, the Spectrum was a rare machine in Kerala, and many students experienced their very first exposure to computers through this platform. Transition phase: By the time Personal Computers (PC) first became available in Kerala through sellers in Ernakulam, Saji Kallat immediately brought them to the institute. The centre introduced IBM PCs and compatibles, starting with Intel 8086 processors that used 5.25-inch floppy disks for storage. Students learned to boot the systems using floppy disks and practiced commands in text-only DOS environments...

In today’s digital world, children are introduced to smartphones, tablets, and the internet at an early age. This exposure opens up opportunities to learn, play, and connect with others, but it also brings certain risks that families need to be aware of. Among these, online privacy has become one of the most important aspects of cyber safety, especially for children who may not always realise the consequences of sharing personal information on the internet. In India, internet access has grown rapidly with affordable smartphones and cheaper data plans, making it easy for families in both urban and rural areas to stay connected. While this digital growth supports education and communication, it also increases the chances of children coming across strangers, scams, or content that may not be suitable for them. Many youngsters use social media platforms, gaming apps, and messaging services where they might share details such as their name, school, address, or photos without considering how...

In the last decade, India has witnessed a remarkable transformation in internet connectivity and speed, reshaping the way millions of people communicate, work, and access information. From a time when dial-up connections and slow broadband were the norm, the country has now emerged as one of the fastest-growing digital nations in the world. This rapid progress has been driven by a combination of affordable data, increasing smartphone penetration, and strong investments in telecom infrastructure that have brought high-speed internet even to smaller towns and rural areas. One of the key reasons behind India’s rise in internet speed and usage is the aggressive expansion of 4G services across the country. Affordable data plans have made it possible for a large section of the population to enjoy high-speed internet, which was once considered a luxury. The introduction of competitive telecom players further pushed down data prices, making India one of the most affordable markets for mobile i...

In the 1970s and early 1980s, many home computers didn’t come with floppy drives because they were too expensive. Instead, they used standard audio cassette tapes (Compact Cassette), the same kind people used for music, to save and load programs. The computer would convert digital data into sound, often a series of screeches and tones, which could then be recorded on a cassette tape. To load the program back, the tape player would send the sound into the computer, which decoded it into digital form once again. This method worked, but it was slow and sometimes unreliable. Loading even a small program could take several minutes, and a misaligned tape head or a damaged portion of tape could easily corrupt the data. One of the most famous computers to use this system was the Sinclair ZX Spectrum, released in 1982 in the UK and also brought to India by enthusiasts. The Spectrum connected to an ordinary cassette recorder through audio cables, while its display output was usually ...

Artificial Intelligence may sound like a futuristic concept reserved for tech companies and research labs, but the truth is that it has already become part of the daily routine for millions of Indians. From waking up in the morning to commuting to work, shopping online, or even managing finances, AI quietly powers many of the tools and services people rely on without even realizing it. One of the most visible examples is the use of voice assistants. Whether it is Google Assistant on smartphones, Siri on Apple devices, or Alexa in smart speakers, Indians interact with AI whenever they ask for the weather, set a reminder, or play a song. These assistants use AI to process natural language, understand accents and regional variations, and deliver quick responses. Similarly, predictive text and autocorrect on mobile keyboards are driven by AI, making typing in English and Indian languages faster and easier. AI is also behind the recommendation systems of popular platforms that Indians use e...
