What is a Time Series?

• Time Series data is a series of data points indexed or listed or graphed with an equally spaced period.
• Time series forecasting is the use of the model to predict future values based on previously observed value.
• Input Past --> Predict future.

Component of Time Series:

• Trend: Increase or decrease over a long period. India GDP
• Seasonal Pattern: Short-term variation occurring due to seasonal factors. Winter sales
• Cyclical Patterns: It is a medium-term variation caused by circumstances, which repeat in irregular intervals. Recession
• Irregularity Patterns: Which Occurs due to unpredictable factors. Anomaly

Where can we not use Time Series?

• If the variable is not dependent on time.
• If Values are constant.
• Values represented using known function as sin(x), cos(x) etc.
• Time Series algorithm cannot be used if data is not stationary.

Time series models:

• ARIMA
• SARIMA
• FARIMA
• LSTM

Yes, Naveen, you can do. You need to start from DevOps basics and make the foundation secure. Practice till you can set up things without looking into steps and docs at least 70% of the process you should be clear. That will help you quickly move into DevOps work. Once you start working, you will automatically understand things.

There is no direct option to add bullets in EXCEL. So we can create the bullets by the following steps:

1. Select the range where you want to apply the bullets.
2. go to formate cell ==> Custom Formate.
3. delete the General word and do following.
4. add five blank space.
5. add your symbol with Alt+7 then add one space.
6. type @ and press ok.

Of course, you can move to DevOps and get jobs in this. You would have to add a couple of skills into your skillset which includes Cloud technology (AWS, Azure, GCP), Puppet/chef/Ansible, Jenkins/Bamboo/Teamcity, Docker and Kubernetes, Terraform, Git, Scripting, Python, Databases, etc.

You will required a couple of months to get on these skills.

Microprocessor & Microcontroller both are integrated circuits.

The microprocessor (MPU) is a controlling unit of a microcomputer. It is stored in a single integrated circuit; whereas Microcontroller(MCU) is a compact integrated circuit design to govern a specific operation in an embedded system.

The microprocessor is a set of instructions having zero status flag, bulky & large no.of instructions, mainly used in personal computers. The microprocessor is the heart of the computer.

Whereas Microcontroller is also set of instructions having no zero flags, as well as fewer instructions, mainly used in the washing machine, MP3 players Microcontroller having RAM ROM, EEPROM embedded in it.
