Circuit switching and packet switching.

Circuit switching and packet switching are two fundamental communication paradigms used in telecommunications networks. Here's a comparison between circuit switching and packet switching:

1. Nature of Communication:

• Circuit Switching: In circuit switching, a dedicated communication path is established between two parties for the duration of their conversation. The path remains exclusive to those users until the communication is terminated.
• Packet Switching: In packet switching, data is divided into packets, and each packet is transmitted independently. Packets may take different routes to reach the destination, and they are reassembled in the correct order upon arrival.

2. Resource Utilization:

• Circuit Switching: Dedicated resources (e.g., bandwidth) are reserved for the entire duration of the communication, even if there are moments of silence or inactivity.
• Packet Switching: Network resources are shared dynamically among multiple users. Bandwidth is used more efficiently as it can be allocated on demand.

3. Connection Establishment:

• Circuit Switching: A connection must be established and reserved before communication begins. This involves signaling to set up the dedicated path.
• Packet Switching: No dedicated path is established beforehand. Packets are routed independently, and connections are established on a per-packet basis.

4. Latency:

• Circuit Switching: Generally lower latency as the dedicated path is established before communication starts.
• Packet Switching: Latency can vary as packets may take different routes and experience different delays.

5. Efficiency:

• Circuit Switching: Less efficient for bursty data or sporadic communication as resources are reserved continuously.
• Packet Switching: More efficient for bursty data as resources are allocated dynamically as needed.

6. Scalability:

• Circuit Switching: Less scalable for a large number of users, as dedicated paths need to be established for each communication session.
• Packet Switching: More scalable, especially in large networks, as resources are shared and allocated on demand.

7. Examples:

• Circuit Switching: Traditional telephone networks (PSTN - Public Switched Telephone Network) use circuit switching.
• Packet Switching: The Internet and most modern computer networks use packet switching.

8. Fault Tolerance:

• Circuit Switching: Less resilient to network failures as a dedicated path is affected if any segment fails.
• Packet Switching: More resilient to network failures as packets can take alternative routes if a segment of the network fails.

9. Cost:

• Circuit Switching: Can be costlier for continuous communication, especially when resources are reserved but not fully utilized.
• Packet Switching: Generally more cost-effective, particularly for bursty and intermittent communication.

10. Adaptability to Different Data Types: - Circuit Switching: Typically optimized for voice and continuous data streams. - Packet Switching: Adaptable to various data types, including voice, video, and data.

circuit switching provides a dedicated and continuous communication path, whereas packet switching divides data into packets and transmits them independently. Packet switching is more scalable, adaptable, and cost-effective, making it the dominant paradigm in modern telecommunications networks.

Give examples how mobile technology evolved and were adopted by thee telecom operators in Nepal.

1. Introduction of Mobile Services:
• In the early 2000s, mobile services were introduced in Nepal. Nepal Telecom (NT) was the first operator to provide mobile services, followed by the entry of private operators.
2. 2G Era:
• During the initial phase, 2G (Second Generation) mobile technology was prevalent. Both Nepal Telecom and private operators like Ncell launched 2G services, enabling basic voice communication and text messaging.
3. Expansion of Network Coverage:
• Telecom operators focused on expanding network coverage to reach remote and rural areas. This involved the deployment of base stations and infrastructure to improve accessibility.
4. 3G Technology:
• Around 2010, operators in Nepal started rolling out 3G (Third Generation) technology. This marked a significant advancement, offering higher data speeds and enabling services like mobile internet and video calling.
5. Competition and Service Differentiation:
• The entry of private operators, especially Ncell, intensified competition. Operators focused on service differentiation, offering innovative packages, data plans, and value-added services to attract subscribers.
6. Mobile Internet Boom:
• The mid-2010s witnessed a surge in mobile internet usage. Telecom operators expanded their 3G networks and introduced affordable data plans, leading to increased adoption of mobile internet services.
7. 4G/LTE Technology:
• In 2017, Nepal Telecom launched 4G/LTE (Fourth Generation/Long-Term Evolution) services, providing even faster data speeds. Ncell followed suit, contributing to the widespread adoption of 4G technology.
8. Smartphone Proliferation:
• The availability of affordable smartphones contributed to a higher penetration of mobile technology. Smartphones became more accessible, leading to increased use of mobile applications, social media, and online services.
9. Mobile Financial Services:
• Both Nepal Telecom and Ncell introduced mobile financial services, allowing users to perform financial transactions, pay bills, and transfer money using their mobile phones.
10. Collaboration with International Partners:
• Telecom operators in Nepal collaborated with international partners and vendors to leverage global best practices and bring advanced technologies to the local market.
11. Exploration of 5G Technology:
• There has been exploration and discussion around the deployment of 5G technology in Nepal. While it was not yet widely implemented as of my last update, discussions and trials were underway to prepare for the next phase of mobile technology.
