- 3. Myth 1 Formatting a Flash Drive is the same thing as Erasing its contents. 3
- 4. USB flash drive A USB flash drive, also known under a variety of other names, is a data storage device that includes flash memory with an integrated Universal Serial Bus (USB) interface. USB flash drives are typically removable and rewritable 1 USB Standard, Male A-plug 2 USB mass storage controller device 3 Test point 4 Flash memory chip 5 Crystal oscillator 6 LED (Optional) 7 Write-protect switch (Optional) 8 Space for second flash memory chip 4
- 5. Flash Memory Flash memory is an electronic non-volatile computer storage medium that can be electrically erased and reprogrammed. 0 V OPEN Programming a Flash MemoryErasure of a Flash MemoryFlash Cell Structure 5
- 6. Formatting 1. Testing each memory cell in the Flash storage device. 2. Identifying all defective cells and taking steps to ensure that no data will be written to or read from a defective cell. 3. Reserving some cells to serve as “spares.” 4. Creating a File Allocation Table 5. Reserving some cells for use by the Flash storage device’s controller 6. Where applicable, reserving some cells for special features Erasing 1. Removing the Address Linked with all the contents stores in the flash drive. Replacing the stored clusters with the newer data replaced. 6
- 7. Myth 2 Graphic Memory is the main factor of graphic whether the PC is having Internal or External Graphic. 7
- 8. Integrated Graphics video card, video hardware integrated into the motherboard or the CPU. Dedicated Graphics An expansion card which generates a feed of output images to a display (such as a computer monitor) 8

- 11. Myth 3 Clock Speed is the main factor of measuring speed. 11
- 12. Clock rate The clock rate typically refers to the frequency at which a chip like a central processing unit (CPU), one core of a multi-core processor is running, and is used as an indicator of the processor's speed. 12
- 13. Front-side bus Refers to the external interface from the processor to the rest of the computer system, as opposed to the back side, where the back-side bus connects the cache (and potentially other CPUs). Cache It is a component that stores data so future requests for that data can be served faster; the data stored in a cache might be the results of an earlier computation, or the duplicates of data stored elsewhere. CPU Cache 13
- 14. Memory bandwidth It is the rate at which data can be read from or stored into a semiconductor memory by a processor, usually expressed in units of bytes/second, Multi-core processor It is a single computing component with two or more independent actual processing units (called "cores"), which are the units that read and execute program instructions. The instructions are ordinary CPU instructions, but the multiple cores can run multiple instructions at the same time, increasing overall speed by parallel computing. 14
- 15. Myth 4 AMD is less good as compared to INTEL. 15
- 16. Early AMD 8080 Processor The die from an Intel 8742 16
- 17. Intel’s Approach 12 cores with 6 shared cores AMD’s Approach 12 cores with 12 dedicated threads 17

- 19. Myth 5 Shift+Del deletes the data completely from the Hard-Disk. 19
- 20. Hard disk drive It is a data storage device used for storing and retrieving digital information using one or more rigid rapidly rotating disks (platters) coated with magnetic material. The platters are paired with magnetic heads arranged on a moving actuator arm, which read and write data to the platter surfaces. Data is accessed in a random-access manner rather than sequentially. An HDD retains its data even when powered off. 20
