Best Machine Learning Book for Beginners

You need a mixof different technologies for Data Science projects. Instead of learning many skills, just learn a few. The four main steps of any project are extracting the data, model development, artificial intelligence, and presentation. Attending interviews with many skills is not so easy. So keep the skills short.
A person with many skills can't perform all the work. You had better learn a few skills like Python, MATLAB, Tableau, and RDBMS. So that you can get a job quickly in the data-science project.
Out of Data Science skills, Machine learning is a new concept. Why because you can learn Python, like any other language. Tableau also the same. Here is the area that needs your 60% effort is Machine learning.  Machine Learning best book to start.

Telecom Domain Knowledge Useful For a Data Analyst

Let us take any telecom company, they provide 5 kinds of services. One is voice service, Toll-free service and the other one is data service. The given domain knowledge in telecom helps you understand about telecom domain quickly.

Telecom Domain Knowledge Useful for IT developers, Data Analyst and Software Testers

In addition to the above, the latest services are Internet service and wireless service. Domain knowledge is crucial to do testing correctly.

Top 5 Telecom services

  • Voice
  • Toll-free
  • Data service
  • Internet
  • Wireless 

1. Voice service

This is the standard phone service that you have been using since the first time you called your Grandma to thank her for a birthday present. You need voice service.

2. Toll-free service


A toll-free number is a special number that enables calls to come in from anywhere without the caller incurring a charge. The called party pays all the charges for the call. How much the called party pays for a call depends on the arrangements made with the long-distance carrier. 

If you look at all of your voice calls and find that the majority of them are inbound from customers, you could probably benefit from toll-free service.

For many companies, not having a toll-free number is disastrous. If your car breaks down and you have to call for assistance from a payphone, would you rather pay 50 cents to contact the answering machine of a tow truck or taxi company, or would you rather call for free? If you’re on hold for a couple of minutes on a toll-free call, at least you’re not paying for it.

3. Data services


The term data services usually refer to non-voice communications such as e-mail, text messaging, and fax services that are transmitted over a private network. In every company, information needs to travel from one side of the office to another side of the office.

The sales team closes the order and relays it to the order-entry department. he order-entry department logs the order and sends it to the manufacturing department; the manufacturing department builds and tracks the order, and the shipping department sends the order to the customer.

4. Internet Service

Every office needs a connection to the Internet, if for no other reason than to enable employees to send and receive e-mail and while away the hours Googling their names.

Many companies use the Internet to research their competitors, or they may use the Internet to visit suppliers’ Web sites to place orders, review shipments, and request services.

5. Wireless service

Wireless service can encompass all the other categories in this list, but because wireless service is usually provided by a different company than the one that provides your landlines, you need to view it as a separate telecom service.
