Wearable devices, supercomputers, and advanced display technologies further illustrate the diverse advancements in ICT.

Evolving Landscape of Information and Communication Technology

• The Metaverse: It is a collective virtual shared space that can be accessed by different devices and platforms. 
  • It is a fusion of augmented reality (AR), virtual reality (VR), and the internet, creating immersive and interactive experiences for users. 
  • It has many potential applications, such as entertainment, education, social networking, e-commerce, and digital art.
• Software 2.0: It is a term that refers to machine-written code, which is generated by artificial intelligence (AI) models based on data and specifications. 
  • It can automate the development process, reduce errors, and optimize performance. It can also enable new services and products, such as autonomous vehicles, smart homes, and natural language processing.
• Blockchain: It is a distributed ledger technology that enables secure and transparent transactions without intermediaries.[UPSC 2020]
  • Application: Digital identity, smart contracts, supply chain management, and decentralized finance. 
• Internet of Things (IoT): It is the network of physical objects that are embedded with sensors, software, and other technologies to connect and exchange data with other devices and systems.[UPSC 2018]
  • Applications: smart cities, smart agriculture, smart manufacturing, and smart healthcare. 
• Quantum Computing: It is a new paradigm of computation that uses quantum mechanical phenomena, such as superposition and entanglement, to perform operations on quantum bits (qubits). [UPSC 2022]
  • It can potentially solve problems that are intractable for classical computers, such as optimization, cryptography, machine learning, and simulation. 
  • It can also accelerate scientific discovery and innovation in various fields, such as physics, chemistry, biology, and medicine.
• Facial Recognition System (FRS)
  • FRS is part of the Digi Yatra initiative (Ministry of Civil Aviation) to promote seamless and hassle-free experience at airports and simultaneously, improving the security. 
  • Digi Yatra Foundation (DYF) has been set up as a joint venture company for creating the Digi Yatra Central Ecosystem. 
  • FRS is a way of identifying or confirming an individual’s identity using their face. It can be used to identify people in photos, videos, or in real-time. 
  • First phase of Facial Recognition System (FRS) is planned at Kolkata, Varanasi, Pune, Vijayawada, Bangalore, Delhi and Hyderabad Airports by March 2023. 
• Wearable Devices: These are electronic devices that are worn as accessories, embedded in clothing, or even implanted in the body to monitor and collect data related to health, fitness, location, and other aspects.[UPSC 2019]

• Supercomputers in India:

• • As of June 2023, the AIRAWAT supercomputer is the fastest supercomputer in India, having been ranked 75th fastest in the world in the TOP 500 supercomputer list. 
  • It has been installed at the Centre for Development of Advanced Computing (C-DAC) in Pune.
  • India has a National Supercomputing Mission that aims to increase the country’s research capability and skills by connecting various institutions with a supercomputer network.

Displays

• • It is a device that displays text and graphics on a screen, allowing the user to see the output of a computer or another device. Some Popular Displays as given below,
  • LED (light-emitting diodes) Display: It is a type of flat-panel display that uses light-emitting diodes (LEDs) as pixels to create images or text. 
    • They are bright, energy-efficient, and durable, and they can be used for various applications such as outdoor signs, billboards, video walls, and stage lighting. 
    • They can produce a wide range of colors and contrast levels by adjusting the intensity and color of the LEDs.
  • OLED (Organic Light-Emitting Diode) Display: This type of display uses a layer of organic materials that emit light when an electric current is applied.[UPSC 2017]
    • Unlike LCDs, OLEDs do not need a backlight, as each pixel can produce its own light. This allows OLEDs to have better contrast, wider viewing angles, and thinner designs. 
    • These are used in some TVs, monitors, laptops, and smartphones. 
    • These can produce vivid and realistic colors, but they may have issues with brightness, lifespan, and burn-in.
  • Plasma Display: This type of display uses a layer of gas that is ionized by an electric current to create plasma. The plasma then excites phosphors that emit light to create an image. 
    • They are mainly used in large TVs. 
    • It can produce high contrast, wide viewing angles, and fast response times, but they may have issues with power consumption, heat generation, and image retention.
  • CRT (Cathode Ray Tube): This type of display uses a vacuum tube that shoots electrons at a phosphor-coated screen to create an image. 
    • They are the oldest and most traditional type of display, and they are mostly used in old TVs and monitors. 
    • They can produce high contrast, wide colour gamut, and low input lag, but they may have issues with size, weight, resolution, and radiation.
  • MicroLED Display: This type of display uses microscopic LEDs that can emit light individually to create an image. 
    • These are similar to OLED displays, but they use inorganic materials instead of organic ones. 
    • These are still in development, and they are expected to offer better brightness, efficiency, and durability than OLED displays. 
  • Quantum Dot Display: It is a type of LCD that uses tiny semiconductor nanocrystals, known as quantum dots, to produce more accurate and vibrant colors than traditional LCDs. 
    • Quantum dots are excited by the blue light from the display panel to emit pure red, green, and blue light, which reduces light losses and color crosstalk in color filters, improving display brightness and color gamut. 
    • They present a favorable alternative to super-premium Organic LED displays (OLEDs), but usually at less cost, and with none of the technical issues and limitations that OLED introduces. 

• Cloud Computing

• • • It is a technology that allows users to access and use computing resources, such as storage, servers, applications, and databases, over the internet, without having to manage them directly. 
    • It has many advantages, such as cost reduction, scalability, availability, reliability, and agility.
    • Examples: Google Cloud, IBM Cloud, Amazon Web Services, and Microsoft Azure. 

• Edge Computing

• • It refers to the movement of data-handling activities or other network operations away from centralized and always-connected network segments (such as Dropbox, Gmail, and so on) and towards individual sources of data capture, such as endpoints such as laptops and tablets.
  • It is a type of cloud computing that differs in the amount of time it takes to process information. 
  • The data is analyzed in real-time, close to where it is stored, and without latency.

Conclusion

• The advancements in ICT are not just technological feats but also catalysts for significant societal change. 
• With applications ranging from smart cities to digital identity verification and cloud computing, these technologies offer immense potential for growth and improvement in various fields. 
• Initiatives like India’s National Supercomputing Mission and MeghRaj cloud computing project underscore the importance of harnessing these technologies for national development. 
• As we continue to integrate these innovations into our daily lives, the future of ICT holds promising opportunities for progress and efficiency.
