• Bootloader :

Defination - A boot loader is a type of program that loads and starts the boot time tasks and processes of an operating system or the computer system. It enables loading the operating system within the computer memory when a computer is started or booted up. A boot loader is also known as a boot manager or bootstrap loader.

Explaination - A boot loader primarily manages and executes the boot sequence of a computer system. A boot loader program is typically started after the computer or the BIOS have finished performing the initial power and hardware device checks and tests. It fetches the OS kernel from the hard disk or any specified boot device within the boot sequence, into the main memory. A boot loader is associated with only a single operating system. An operating system can also have multiple boot loader programs classified as primary and secondary boot loaders, where a secondary boot loader might be larger and more capable than the primary boot loader.

• Kernel :

Defination - A Kernel is the core component of an operating system. Using interprocess communication and system calls, it acts as a bridge between applications and the data processing performed at the hardware level. When an operating system is loaded into memory, the kernel loads first and remains in memory until the operating system is shut down again. The kernel is responsible for low-level tasks such as disk management, task management and memory management.

Explanation - A computer kernel interfaces between the three major computer hardware components, providing services between the application/user interface and the CPU, memory and other hardware I/O devices. The kernel provides and manages computer resources, allowing other programs to run and use these resources. The kernel also sets up memory address space for applications, loads files with application code into memory, sets up the execution stack for programs and branches out to particular locations inside programs for execution.

• Virtual Private Network :

A Virtual Private Network (VPN) is a network that is constructed using public wires, usually the Internet, to connect remote users or regional offices to a company's private, internal network.

• Bootloop :

Bootloop means your phone doesn't but up right, it's just starting and starting and nothing happens, or it's starting and shutting down and starting again. It just means your phone makes a loop while booting

##• Soft Brick and Hard Brick :

When your phone boots and shows the screen and then immediately and automatically turns off, or it keeps restarting with vibrations, or it is totally dead without any visible signs, all these signals indicate that your phone is bricked

Soft Brick - Soft brick is the state of android device due to some software problems like bootloops or device freezing at some point during boot. This may occur if some software problem occurred in the device mainly during OS upgrade or flashing something such as a custom ROM, camera mod or app in your custom recovery mode. A soft-bricked device is only half-dead. Because of this, your device is not booting anymore or is constantly crashing but can be recognised by a computer.

Hard Brick - Hard brick is the state of android device that occurs when your device is unbootable without a bootloop. A hard Brick device generally show little to no signs of life. If this happens, you had better to buy a new device since your device is showing you a black or grey screen at this point.

• Firmware :

Defination - Firmware is a software program permanently etched into a hardware device such as a keyboards, hard drive, BIOS, or video cards. It is programmed to give permanent instructions to communicate with other devices and perform functions like basic input/output tasks. Firmware is typically stored in the flash ROM (read only memory) of
