I can have a full function LAN never connect to internet?

I can have a full function LAN connect to internet?

All confidential information store in the LAN never connect to internet?

A full function LAN connect to internet only for communication? Never store confidential information in the LAN connect to internet?

If there are 2 full function LANs - the first full function LAN store all confidential information never connect to internet; the second full function LAN have no confidential information connect to internet.

How many computers needed in the first full function LAN? How many computers needed in the second full function LAN?

1 System target: computer shop with cyber cafe, free multimedia interactive business education courses, Surf & Dine Combinations
2 System target: Garment factory, supply garment, accessories: hats, shirt, jacket to the computer shop

486 processor
16MB RAM (32MB suggested)
100-500 megabytes of hard disk space for a minimal and around 3.5GB for full install
3.5" floppy drive

Additional hardware may be needed if you want to run the X Window System at a usable speed or if you want network capabilities.

What's the system function?

Performance requirements: storage limit, time limit, speed limit, security, etc

System environment and resources requirements?

Reliability requirements?

Security requirements?

User interface requirements?

Cost and development requirements?

Extend requirements?

There are many cheap used computers.

I have 4 computers, 1 ADSL modem, 1 switch/exchange, network adapters, some parts; 7 Hard Drives.
Number Categary Serial Number Model Type Capacity MAC: Web UserName Password Owner Location

Test 2 full function LANs - the first full function LAN store all confidential information never connect to internet; the second full function LAN have no confidential information connect to internet.

Test: 1 Computer shop with cyber cafe; 2 Garment factory.

 

90% of your message doesn't make sense or doesn't appear relevant... I don't mean any offense, but if English is a second language, you might want to seek help from someone in your native language, you're going to be given answers that are going to be difficult to translate.

From what I can make out:

1. If you download a distribution CD, check it's MD5 sum against that which is advertised on the official distribution homepage, that assures what you received is legitimate.

2. You'll want a very lean distro to run reasonably on such low spec computers. If it will run/install at all. That is a very low amount of RAM, and you will have issues with booting to a live cd. I know "Arch Linux" only requires 64mb to boot a minimal install disc, but to actually run the installed environment it might be very sluggish, and will absolutely require a swap partition and expect a lot of hard drive activity. You'll also need a lightweight WM, don't be expecting full installs of Gnome or KDE to cooperate. Gentoo is another lean distro, but is probably not for you.

3. Networking is trivial to set up, especially if your modem acts as a DHCP server. Networking between Windows and Linux systems is easy too, if it isn't included in the distro you just need to install and configure Samba shares.

For the time wasted in trying to get these systems working, and the complete lack of productivity on them (if you are paying people to use these systems, it is going to take 3-4 times longer than it should to actually do any meaningful work), it is probably worth investing in some newer hardware. Less work for you in setting them up, MUCH lower risk of them breaking down, and much higher productivity from workers, they'll pay themselves off in short time.

 

64 will run a core system, a minimal fluxbox gui with rox and an irc client.. that will eat up about 20 ( I know well that 64 isn't any use for anything )... you can't run a css enabled browser, and network services??? sftp, apache,.. nah.. don't waste the time. Win95/98 will do a better job on those specs... The best use for machines like that.. because modern apps are going to choke on the slow processor speeds and lack of ram... is... network storage devices, printer servers and firewalls.. Anything under a p3 800 with 512 ram is going to be a waste of time in any serious work environment.

The 486.. I doubt you will get any gui at all on it.. even dsl doesn't work on graphics hardware from that era.. If it has onboard graphics chances are it's only 4bit... again.. windows 95 should work quite well, but networking is going to be erratic to say the least.

(trust me.. I know all about linux on antique hardware. I don't own a computer made this century)
