How the Computer get Boot Up inside process.



When you press a button on the PC to start the system. Many processes get invoke which make operating system run. So, what happens is when you press the power button immediately kernel present in main memory get invoke. Kernel is main part of the operating system.

Kernel is the system code which work as translator between hardware and operating system.

Imagine who you will use hard disk without operating system? Can you?

In my opinion it’s not possible to interact with hard drive we need an OS.

OS interact with kernel and kernel interact with hardware.

SO, let’s get to the point as soon as the kernel get activated, it calls the OS file from drive into the ram.

Note: To do anything with file of your hard drive it has to be call in RAM first where it can make change you want. As we know ROM (Read Only Memory) in hard drive we can only read memory that is why we require ram to execute any task on computer.


 As the OS come into the RAM system boot up and we the screen of the Operating System.
This is how OS get boot up.

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...

Troubleshooting and debugging

Troubleshooting is the process of identifying, analyzing, and solving problems.  Debugging is the process of identifying, analyzing, and removing bugs in a system. We sometimes use troubleshooting and debugging interchangeably.  But generally, we say troubleshooting when we're fixing problems in the system running the application, and debugging when we're fixing the bugs in the actual code of the application. Debuggers let us follow the code line by line, inspect changes in variable assignments, interrupt the program when a specific condition is met, and more. System calls are the calls that the programs running on our computer make to the running kernel.   A reproduction case is a way to verify if the problem is present or not. Where to check for log file in OS? On Linux , you'd read system logs like /var/log/syslog and user-specific logs like the .xsession-errors file located in the user's home directory. On MacOs , on top of the system logs, you'd go through...
