IT rookie of computer software

 Classification of a computer system

32-bit operating system: 32 / u; more provincial resources; support 4G memory within

64-bit operating system: 64 / u; faster; support memory than 4G

Memory Unit: B KB MB GB TB Conversions: (2 to the power 10) 1024

Computer Configuration: digit chooses need to decide based on memory capacity

Second, the server category

Blade servers (placed inside the room)

Closet server (in the office)

Third, Microsoft to file naming rules

32-bit x86-digit (more saving time, on memory usage) x64 64 bit (faster) 32/64 refers to the system

Representation: 32 32bit x86 architecture (PC configuration to meet) i386 i486 i586 i686

64 64bit x64 x86 64 (86 Architecture 64-bit operating system)

(Digits: number of parallel computing computer or CPU can handle a maximum number of bits)

(System memory determines the number of bits, threshold memory (Yu) 4G value, less than a 32-bit, 64-bit or greater)

(Supports only 32-bit memory within 4G; 64-bit support more than 4G memory)

(Median replacement system need to re-install the operating system)

Fourth, File System File System

a, FAT32 advantages: compatibility is particularly good Cons: only supports a single file within 4G

exFAT (extend extension) allow more than a single file, but poor compatibility 4G

32 the version number (FAT8, FAT16, FAT32, exFAT)

b, NTFS advantages: poor compatibility disadvantages: almost no upper limit of a single file (2T)

Modify the file system can only format 

Fifth, how to use the new Windows

1, restore factory settings

2, reinstall the operating system

Demand for physical installation system:

1, a USB (8G above): Kingston, SanDisk (USB3.0 / 2.0)

2, a software (through excellent start: U disk maintenance tool (cabbage, old peach); floppy disk through UltralSO)

3, a file (image file / image file ISO) system image (1, mounted version; 2, a key ghost Edition)

iso: disc image file (image file) --- is to convert the data to an optical disc in a form of separate files

4, a computer
