| re: LAN without a hard disk
Hi
LAN without a hard disk means a computer is running without storage device.
As per IBM standard the following devices & parameters must be followed.
A Personnel Computer means the following architect is a standard
1. MICRO PROCESSORER (Min XT 8088) Other AT 286, 386, 486, Pant1, Pant2, Pant3, Pant4 Etc. from 4Mhz to 3.8 Ghz
2. ROM (BIOS)
3. RAM (Min 640 KB) Ext Memory 1GB
4. PEREPHERIALS INPUT / OUTPUT (Min Keyboard & VDU) Other Mouse Printer Etc.
5. EXTENSION SLOTS (Min 2 No 8 Bit ISA) Other VISA, VL-VISA, PCI etc.
6. DATA STORAGE DEVICE (Min FDD 1.2MB or 1.44 MB) Other HDD 10MB to 80GB
7. COMMUNICATION PORT (Min COM1, LPT1) Other COM2, LPT2, USB etc.
8. OPERATING SYSTEM (Min DOS 3.2) Other DOS 6.22 Win 3.1 to Win Vesta
Now come on the point, Without Operating System a PC cannot work so minimum requirement of OS is Disk Operating System is also known as DOS
For Operating System DOS 3.2 can work with only three Internal Command that is IO.SYS, MSDOS.SYS and COMMAND.COM is also Known as System Files and loaded in to the basic RAM at the time of BOOTING.
Now for LAN Operation you have to connect a LAN CARD/DEVICE Internal or External with proper LAN Driver with a Computer.
For INTERNET Sharing & operation you have to require an Internet Browser.
Therefore a storage device is necessary for installation of OS, Installation of LAN Driver and operation of Internet Browser etc.
Hope now you will understand the basic logic and PC operation.
Thanks
