The Government to Citizen model of e-governance refers to the digital delivery of public services and information directly to individual citizens. Examples include applying for birth certificates, paying taxes online, or accessing land records. This model aims to make government services more accessible, transparent, and efficient, reducing the need for citizens to visit physical government offices for.Explanation
Rajasthan has launched several specific e-governance initiatives, such as RajSampark for grievance redressal and RajeGyan for education. The Jan Aadhaar scheme is a particularly significant project that provides a unique "One Number, One Card, One Identity" for every family. This unified system simplifies access to various government welfare schemes and ensures that benefits are delivered accurately.| Digital India Initiative | Objective/Feature |
|---|---|
| A. BharatNet | i. Online education platform |
| B. e-Hospital | ii. Broadband connectivity to Gram Panchayats |
| C. SWAYAM | iii. National agriculture market portal |
| D. e-NAM | iv. Online registration and medical records |
Explanation
Digital India includes diverse initiatives with specific objectives: BharatNet provides broadband to rural areas, e-Hospital manages medical records, SWAYAM offers online education, and e-NAM provides a national platform for agricultural trade. Together, these programs address different aspects of digital empowerment and service delivery, creating a more connected and efficient nation through the strategic use of technology.Explanation
Government to Citizen services focus on providing direct benefits or information to the public, such as online tax payments, passport applications, or digital land records. These services enhance the citizen’s experience with the government. An inter-departmental memo sent through an e-Office system is an example of Government to Government communication, as it involves internal administrative processes.Explanation
Direct Benefit Transfer is a government mechanism designed to transfer subsidies and welfare payments directly into the bank accounts of beneficiaries. By using the Aadhaar-linked payment system, DBT eliminates middlemen and leakages, ensuring that the full amount reaches the intended recipient. This transparent and efficient system has significantly improved the delivery of various social welfare schemes across.Answer key for these questions

Key facts from Computers, Information and Communication Technology
- First-generation computers used vacuum tubes; the second generation moved to transistors.
- Analog computers work on continuous variable data rather than discrete binary data.
- The Control Unit directs and coordinates the operations of the CPU.
- Cache memory gives the fastest access to the CPU; the hierarchy from fastest to slowest is registers, cache, RAM and magnetic disk.
- Adding more RAM to a system with many page faults reduces its dependence on virtual memory.
- An SSD differs from an HDD by the use of NAND flash memory.
Frequently asked questions
How many RAS Prelims practice MCQs are there on Computers, Information and Communication Technology?
This page has 200 practice MCQs on Computers, Information and Communication Technology (Science and Technology). Each has the correct answer, and most have an explanation.
What was used in first-generation computers?
Vacuum tubes. They were large, used much power and produced heat. The second generation replaced them with transistors, which were smaller, faster and more reliable, and later generations moved to integrated circuits and microprocessors.
Which memory is fastest for the CPU?
Cache memory, apart from the registers inside the CPU. The memory hierarchy from fastest to slowest is registers, cache, RAM and magnetic disk, and capacity increases as speed falls.
How does an SSD differ from an HDD?
An SSD stores data in NAND flash memory with no moving parts, while a hard disk drive uses spinning magnetic platters. As a result an SSD is faster, quieter and more resistant to shock.
