Metropolitan Area Networks – an overview

Computer networks have evolved greatly over the years. In this modern-day and age, there are multiple types of networks like Metropolitan Area Network that satisfy specific requirements for millions of various users.

What’s a Metropolitan Area Network?

A Metropolitan Area Network is a computer network based in a metropolitan or city area, through a connection of multiple LAN. It can access by point to point connections. By combining smaller LAN networks, MANs have the ability to extend to a geographical area of 5 to 50 km. It is sufficient for the network requirements of a city. This interconnection of networks across the city may also end up facilitating connections to WAN.

Use of MAN technology

MANs are particularly useful for the purpose of sharing resources specific to regions, assisting in the quicker and segmented flow of data and information. Furthermore, MANs can connect multiple computers and networks to serve as an Internet Service Provider. This is because of which the internet service provided by a telephone company falls under the category of a MAN connection. A Metropolitan Area Network is smaller than the area covered through WANs. It is much bigger than the connectivity capabilities of a LAN.

Working methodology of MAN

The working mechanism of a MAN is quite similar to that of an Internet Service Provider. However, it is not owned by a single organization. A MAN delivers a joint and shared network connection to all of its users based on a data link layer. This data link layer is classified as a Layer 2 of the OSI model. It is also known as Open Systems Interconnection.

The primary goal of a MAN is to establish a connection between geographically separated LANs. It means that a MAN seeks to form a communication link between two independent LAN nodes. It establishes using optical fibers cables. In order to refresh memory, a switch is responsible for filtering data inflowing in the shape of frames. The switch lies as one of the fundamental components as it is actively responsible for dual tasks. At one end, it filters data and on the other end, it manages the connection.

Types of MAN technologies


Fiber Distribution data interface is a standard for data transfer in context to a LAN and it can assist in transmitting the data of thousands of users. It uses optical fiber for its primary infrastructure; hence the name fiber distributed data interface.


Switched multi-megabit data service allows the transfer of data through a connectionless service. It is the state of data transfer when the information and data stores in the head and then it reaches

its specific destination in an independent manner.


Asynchronous Transfer Mode is the most frequently used MAN technology. However, ATM is a digital transfer technology to transfer real-time data over an individual network. In ATM, the data stores in specific and fix-size packets transferring overtime.



How artificial intelligence is transforming the world

The digital future of work.jpg

Advances in technology pose huge challenges for jobs. Productivity levels have never been higher in some countries. Technology is not the only reason, but it is probably the most important one. Research has been conducted by the students of Engineering Colleges in Jaipur. However, it shows that technology will affect almost every occupation. For instance, self-driving vehicles could hack the need for drivers of taxis and long-haul trucks. In addition, online education could enrich options for the retraining of displaced workers.

Role of policymakers to bring changes

Policymakers play a very important role in the fourth industrial revolution or the second machine age. However, there is a remarkable lack of data available on basic questions like:

  1. What is the scope and rate of change of the key technologies, especially artificial intelligence (AI)?
  2. Which technologies are already eliminating, augmenting or transforming which types of jobs?
  3. What new work opportunities are emerging, and which policy options might create jobs in this context?

This scarcity of information will lead to missed opportunities. In some cases, it could be disastrous. However, if students of B Tech Colleges want to understand, prepare for and guide the unpredictable impacts of advancing technology, they must radically reinvent their ability to observe and track these changes and their drivers.

Use of components to search for information

There are many components of a fit-for-purpose, data infrastructure are already in place. Digital knowledge about the economy is multiplying and has exceptional accuracy, detail, and timeliness. However, the private sector is increasingly adopting different approaches to generate data and using them in decision-making. It includes A/B testing to compare alternatives. Similarly, technologies that protect privacy while allowing statistical summaries of large amounts of data are increasingly available.

The creation of an integrated information strategy by the students of Top Engineering Colleges in Rajasthan can combine public and privately held data. In addition, this would provide policymakers and the public with ways to negotiate the evolving and unpredictable impacts of technology on the workforce. Based on this, the policymakers will adopt an evidence-based ‘sense and respond’ approach. It is pioneered by the private sector.

Data gaps

Much of the data needed to spot, understand and adapt to workforce challenges are not gathered in a systematic way. In some cases, they do not even exist. The irony of our information age is that despite the flood of online data, decision-makers often lack timely, relevant information.

More experimentation

Taking benefits of existing data needs a change in mindset. Over the past decade, many corporations have moved from a ‘predict and plan’ approach to a ‘sense and respond’ one. However, it allows them to adapt quickly to a rapidly changing environment. By continuously collecting massive volumes of real-time data about customers, competitors, suppliers and their own operations, companies have learned how to evolve their strategies, product offerings, and profitability.
