 Keyword  Description
 MBR    
MBR Stands for  " Master Boot Record ." An  MBR  is a small section of a hard disk or other storage devices that contains information about the disk. It is located in the boot sector and defines the disk partitions as well as the code used to start the boot sequence
 SMTP  SMTP stands for Simple Mail Transfer Protocol. It is a dedicated application that's primary purpose is to send and receive emails.  
When you send an email (say xyz@gmail.com ), the SMTP server decides which server to send the message (in this example Gmail servers). Gmail will download the mail and show it in the inbox of xyz@gmail.com.
 Domain  All the websites have an IP address associated with it but it is very difficult to remember to solve this issue we use domain names. Domain Name associate the IP address with a name which is easy to remember
 GPT  GUID Partition Table  (GPT) disks use Unified Extensible Firmware Interface (UEFI). One advantage of GPT disks is that you can have more than four partitions on each disk. GPT is also required for disks larger than two terabytes (TB).
 Emulate  In computing , an  emulator  is hardware or software that enables one  computer  system (called the host) to behave like another  computer  system (called the guest). ...  Emulation  refers to the ability of a  computer  program in an electronic device to  emulate  (or imitate) another program or device.
 Bootable drive  The disk drive  that contains the operating system.
 Software cracking Software cracking  (known as "breaking" in the 1980s ) is the modification of  software   to remove or disable features which are considered undesirable by the person cracking the software, especially  copy protection   features (including protection against the manipulation of software, serial number, hardware key, date checks and disc check) or software annoyances like  nag screens  and  adware .

crack refers to the means of achieving, for example a stolen serial number or a tool that performs that act of cracking.Some of these tools are called keygen, patch, or loader.

 ISO The name  ISO   is taken from the  International Organization for Standardization  (ISO)  ISO 9660   file system used with  CD-ROM   media, but what is known as an ISO image might also contain a  UDF   (ISO/IEC 13346) file system (commonly used by  DVDs  and  Blu-ray Discs ).

ISO images can be created from optical discs by disk imaging software, or from a collection of files by optical disc authoring software, or from a different disk image file by means of conversion. Software distributed on bootable discs is often available for download in ISO image format. And like any other ISO image, it may be written to an optical disc such as CD or DVD.

 UEFI   The Unified Extensible Firmware Interface (UEFI) is a specification that defines a software interface between an operating system and platform firmware.
UEFI is essentially a tiny operating system that runs on top of the PC's firmware, and it can do a lot more than a BIOS. It may be stored in flash memory on the motherboard, or it may be loaded from a hard drive or network share at boot. Different PCs with UEFI will have different interfaces and features.
 BIOSBIOS (pronounced: /ˈbaɪɒs/, BY-oss; an acronym for Basic Input/Output System and also known as the System BIOS, ROM BIOS or PC BIOS) is firmware used to perform hardware initialization during the booting process (power-on startup), and to provide runtime services for operating systems and programs.
 OS(Operating System)An operating system (OS) is system software that manages computer hardwaresoftware resources, and provides common services for computer programs.
 NTFSNTFS. Stands for "New Technology File System." NTFS is a file system introduced by Microsoft with Windows NT and is supported by subsequent versions of Windows, such as Windows 2000 and Windows XP. NTFS has a number of advantages over the previous file system, named FAT32 (File Allocation Table).
