What's Game Engine?



A game engine is software development environment used for creating games. Basically, it’s a framework with inbuilt feature to make the development of the game smoother and save time.

Just imagine if you are not using game engine and you want to create a game then you have to start from scratch. You will have to write the mandatory code which required by every game.
1.     Physic and Collision code.
2.     Render (for render 2-D and 3-D images)
3.     Sound
4.     A.I
5.     Memory management
And many more.

The above mention thing comes in built in the game engine by default. So, you don’t require to write the same code every time and waste time.

But there is some exception when it’s better to create your own engine is when your game demand some optimized performance which a typical game engine can’t provide.
Memory Management a key feature of game engine. Keep the track of the next line to be executed fetch it to the main memory.

For example, In Super Mario when your character move forward new obstacles comes in the way. That were memory management is used game engine execute the next code when the character moves forward at the same time some obstacle is left behind which can’t be accessed again once it gets out of the screen. This happen because engine remove the code which is been fully executed from the main memory to make room for next line if code in the main memory.

Does a better make a better game?

Certain engine can male more realistic and detailed games, but creativity and passion 
make “great” game. There is no “best” engine. It depends on you and your game.



Conclusion:

Game engine helps us with core task so we don’t have to start project from scratch.

TCP Segment

A TCP segment is made up of a TCP header and a data section. Source Port :  A source port is a high numbered port chosen from a special section of ports known as ephemeral ports. A source port is needed so that when the web server replies, the computer making the original request can send this data to the program that was actually requesting it. It is in this way that when it web server responds to your requests to view a web page that this response gets received by your web browser and not your word processor. Destination Port : port on which the client in request the data( The destination port is the port of the service the traffic is intended for ) Sequence Number :This is a 32-bit number that's used to keep track of where in a sequence of TCP segments this one is expected to be.There are limits to the total size of what we send across the wire. In Ethernet frame, it's usually limited in size to 1,518 bytes, but we usually need to send way more data than that. At the transp...
