Let us begin with IP Addresses.
What is an IP Address?
► An Internet Protocol address is a numerical label assigned to each device (e.g., computer, mobile phone) that is connected to a computer network that uses the Internet Protocol for communication.
► An IP address is used for two purposes:
1) To identify whether the interface is host or network.
2) To determine the location of the device.
► IP Versions: IPv4 and IPv6.
Although IPv4 is the earlier version, it is the most commonly used version.
► IPv4 is a 32-bit decimal number while IPv6 is 128-bit number.
► IPv4 is normally written as four numbers between 1 and 255, each separated from the other by a decimal point.
This standard is called as DOTTED-DECIMAL NOTATION.
► Ex: 115.241.40.93
► There are countless IP addresses in today's world!
See for which purpose we need the IP Address------
------------------------------
What is the purpose of IP Address Classes?
Each IP Address Class provides the following information:
► Class A: First 8 bits → NETWORK ID & remaining 24 bits → HOST ID
► Class B: First 16 bits → NETWORK ID & remaining 16 bits → HOST ID
► Class C: First 24 bits → NETWORK ID & remaining 8 bits → HOST ID
► Class D: It represents a 32-bit multicast group ID.
► Class E: It is currently not being used. (NO need)
► For example,
Let us consider the IP Address 203.43.21.12
We know that it belongs to Class C.
Therefore, the NETWORK ID is 203.43.21 and the HOST ID is 12.

1. Backlight Levels/ Screen Brightness.
------------------------------
You don’t always need the brightest screen for using your Laptop. A small change in the brightness of your Laptop screen can result in giving few extra minutes on battery as the LCD screen uses the bigger part of your battery energy.
2. Multi Media/ Entertainment
------------------------------
Okay, you laptop has all the function including the ability to play games, movies and music. But cutting on them would also bring a drastic change in the battery backup of your Laptop.
3. Heavy Applications
------------------------------
You might avoid running heavy application all the time. And try keeping them closed when you are not using them. Avoid using them (if not urgent) when you are on battery, you can always get back to AC plugin and do it later.
4. Wireless and Bluetooth
------------------------------
The wireless system for your Computer sends and receives data packets which also require some energy. You can disable it when you are not using a wireless connection.
5. Heating Issues
------------------------------
Heat is the biggest enemy of any electronics device, same goes with Laptops, try using Laptop without making it too hot. Avoid blocking the air which comes from the laptop fan.
6. Using AC Adapter
------------------------------
Few people say that you should not keep your laptop plugged in when it is charged completely, it’s all wrong. Laptops manufactured these days are smart enough to stop charging the batteries when they are fully changed. Try using your Laptop with AC adapter plugged in.
