WHAT'S ON YOUR MIND
The richest man in China said, “If you put the
bananas and money in front of the monkeys, the
monkeys will choose bananas because the monkeys don't know that money can buy a lot of bananas. In fact, if you offer WORK and BUSINESS to people, they will choose to WORK because most people don't know that a BUSINESS can make more MONEY than a salary. One of the reasons the poor are poor is because the poor are not trained to recognize the entrepreneurial opportunity. They spend a lot of time in school and what they learn in school is to work for a salary instead of working for themselves. Profit is better than wages because wages can support you, but profits can make you a fortune.

THE BOOT PROCESS
It is the process by which PC computer systems come to life,
The boot process begins when the user presses the power switch and starts the system.
When you press the power Botton, the process initiates the Power On Self-Test (POST). Before the power leaves the power supply, the power supply conducts its own POST, making sure voltages and current levels are acceptable. The electrical current from the
power supply follows a predetermined path to the CPU.
Signals are sent from the CPU to the system bus (main electrical pathway) to ensure that the bus is properly functioning. If this test passes, POST continues to the next step The CPU next tests the RTC, or system clock. This clock keeps all system electrical signals in synchronization.

SHORTCUT V1RUX
Shortcut virus, also known as 1kb shortcut virus, is a common Trojan virus that spreads widely using a USB drive or pen drive as a medium. The virus will hide all the folders on the root directory of the USB, and then create a shortcut with the same name as the folder. These shortcut files end with .EXE, .VBS. LNK or .INI suffixes and cannot be cleaned up. After the user clicks on the shortcut, it will run the virus and add it to start automatically

V1RUX
If you've plugged in a USB drive or SD card and found that your files are missing and replaced with shortcuts, your USB drive has likely been infected with a shortcut virus. Luckily, your data still exists—it's just hidden by the virus. You can remove the virus using a free tool like UsbFix or by running some commands at the command prompt. Once the virus is removed from the flash drive, do a full scan of your computer using you preferred antivirus tool before reconnecting the USB drive.

PARTITION
Typically FAT12, FAT16, FAT32, and NTFS partitions and file systems are used when running the various flavors of the Windows operating systems. These partitions can be created by utilities
that ship with the Windows operating system, such as FDISK, DISKPART, or Disk Manager. Other partition types that are often encountered are Linux Native (EXT2/3 and Reiser) and Swap partitions, Solaris (UFS), and Mac OSX (HFS+), As
with Windows operating systems, partitioning utilities ship with these operating systems. You can also use third-party partitioning utilities to create partitions of varied types

PARTITION
Partitions and volumes are terms that are often used interchangeably. Usually this doesn’t cause a problem because typically they are the same thing. There are, however, some subtle
differences, and defining the terms and understanding the differences is an important part of being a professional.
A partition is a collection of consecutive sectors within a volume, and those sectors are addressable by a single file system specific to and contained within that partition.
-A volume, by subtle contrast, is a collection of addressable sectors that are used by an operating system or an application to store data. The addressable sectors in a volume do not have to be consecutive and therein lies the difference. Rather, they need only give the appearance of being consecutive. When a volume consists of a single partition, the two are functionally the same. When
a volume spans more than one partition or drive, the difference becomes self-evident. Volumes are logical storage units that are assigned drive letters by the operating systems. Theoretically,
most operating systems can support up to 24 volumes, using the letters C through Z and reserving A and B for floppy drives. If a single physical hard drive were installed in a system,
that drive could, in theory, be partitioned into 24 volumes.

MENTAL ASPECT
The mental aspect is the key to be successful in anything.
It's the power to motivate yourself, fight on if it hurts, being self
disciplined, paranoid & realistic, calculate risks correctly and do stuff you don't like but are important even if you'd like to go swimming now.
