A message from the Vice Chairman

The HAPCS has two kinds of meetings. Firstly the regular Sunday night meeting which most members attend regularly, secondly the monthly (approximately) planning meeting which organizes the business of the Society, including what happens on the Sundays. The planning meeting is held on Monday, a week after the regular meeting in which all members of the Society are urged to attend. At the planning meeting, we discuss feature speakers for regular meetings, finances, membership, training, and other computer related subjects.

Meeting schedule for the upcoming year


Networking Made Simple:
How to Install a Small Network in Your Home or Small Business
Robert T. MacCara

Network Simply put, a network is computers, printers, faxes, and other electronic devices linked with cables so all the pieces can 'talk' and work together. We will first talk about some terminology to make sure that we're all discussing the same things here! We will only be talking about basics here, and I don't expect that you'll be able to go home and immediately setup your own network, but you should have the groundwork covered in any case with what will be presented here.

Which network is right for you?

You have two types of network configurations to choose from - peer-to-peer and client-server. Your choice depends on the number of PCs, printers, and other devices you want to connect and the types of software applications you work with.

Peer-to-peer network if you have five or less nodes to connect, you'll probably want a peer-to-peer network. A central controlling device called a hub is a what ties the nodes together. Each computer is an equal or 'peer' of the others, and can share files and peripherals connected to the network. While a peer-to-peer network is a low-cost, easy-to-install solution, it is not as efficient for sharing large and complex files, such as databases or graphics.

Client-server network if you have six or more nodes to connect, and work with large files like databases or information that is updated frequently, your best choice is a client-server network. The presence of a central computer, or server, in this configuration gives you several advantages. Because files are stored in a single location, they're easier to update, back up, and archive with dependable results. The server itself is typically a high-performance computer that ensures speedy data access and delivery, and gives you the platform to add capabilities such as centralized accounting.

Cabling comes in several varieties, including coax, twisted pair, and fiber.

Coax cable the most common types of cabling for smaller networks are coax and twisted pair. Coax resembles cable TV wire. It has the benefit of not requiring a hub and can be used to connect large numbers of computers together in a single 'string.' Coax was the first standard cabling type; however, it is less flexible than newer twisted-pair cabling and doesn't support high-speed technologies. Twisted-pair cable twisted-pair cabling resembles the wire that connects your telephone to the wall jack. Its low cost, ability to make easy additions and changes to the network, and built-in path to high-speed technologies such as Fast Ethernet gives you more advantages. Networking technologies include Ethernet, Fast Ethernet, Token Ring, FDDI, and ATM. The two most popular choices for networks are:

Ethernet transfers information at 10 megabits per second (Mbps) in small bursts of data called 'packets' to ensure accurate, efficient operations.

Fast Ethernet, also known as 100BASE-TX; it is 10 times faster than Ethernet, transferring information at 100 megabits per second. Fast Ethernet is ideal for sending large, complex files such as databases and graphics.

Ports generally speaking, the point at which a device connects to the network so that data can pass through. The simplest example of a port is the point where you plug your telephone into the wall.

Node

Any computer, printer, modem, fax machine or any other device connected to the network.

Network software requirements

A network operating system is required for every network. It allows computers and other connected devices to send and receive information. Network operating system software can range from simple to more robust. Peer-to-peer networking features are built into Windows 95, LANtastic, and the Macintosh OS. Client-server configurations require more sophisticated network operating systems like Novell NetWare or Windows NT Server.

Network Interface Cards (Nic)

Network interface cards work with software to send and receive messages on the network. Every desktop or notebook computer on your network needs a network interface card. Ethernet network interface cards are available in 10 Mbps, 10/100 Mbps, and 100 Mbps configurations. They are available for notebook and desktop computers. Dual function 10/100 Mbps network interface cards let you keep your options open if you're planning an upgrade to Fast Ethernet in the future. Ethernet network interface cards are plugged into your computer's expansion slot. They are available in ISA, EISA, MCA and PCI configurations.

Hubs

Also called a 'repeater', the hub is the central point of connection in your network that makes resource sharing possible. Ethernet and Fast Ethernet hubs are available in several port configurations. The most common sizes are 4, 8, and 16 ports. Generally you can daisy chain them together to increase the number of nodes.

Increasing functionality of your network once you have a local area network (or LAN) installed, your options are just beginning. You can add more devices such as switches, remote access devices and resource servers to increase your advantages.

High performance for power users: switches

Graphic designers, engineers, database users-anyone who works with large, complex applications can seriously slow down your network performance. That's when you may want to consider a type of hub called a switch, which lets you pinpoint data delivery to your power users. You also may want a switch if your operations are growing, because it can divide a large network into smaller, more manageable segments.

Shared and switched connections on most networks, everyone shares the capacity of that network. If you have a 10 Mbps network, the capacity remains 10 Mbps even as you add more users and introduce more complex applications such as graphics or images. This can create bottlenecks and slow down performance. Switching allocates data for delivery to a specific user or group of users. For example, if you have two computers on your network who are regularly sending or receiving large image files, they could be using substantial amounts of the network's capacity by themselves. Installing a switch would allow you to deliver additional capacity directly to these power users without impacting performance for the rest of the network.

Solutions for resource sharing

Print, fax, and CD-ROM servers can bring added productivity to your network by allowing you to share these expensive peripherals. By installing a print server you can attach less costly devices, such as ink-jet printers, directly to your network, eliminating the need to buy a network-ready printer. The server can even prioritize jobs and print them in the order you want. A fax server lets you send and receive faxes directly from your desktop, increasing productivity and eliminating the need for additional fax machines, as well as additional telephone lines. A CD-ROM server provides network-direct connections for many CD-ROM drives, allowing employees from different areas to access these drives simultaneously.

How to Network in Windows95

Now that you've installed the Nic's and run the cable from each node to the hub, how do you tell the OS that you wish to start taking advantage of the network? You start by right clicking on the Network Neighborhood icon or select the Network icon from the Control Panel. You first want to Add an adapter - that's the network card you've installed in the computer, and it will show up in the Control Panel under System and Device Manager and Network Adapter. Next thing is to select the Client you wish to use. In our case, it will be Client for Microsoft Networks. Next add the protocol - NetBEUI or TCP/IP. Last thing to do is to add the Service File and Print Sharing. So the OS knows which nodes it should talk to, you must also specify a Workgroup name - you can use your imagination for this one, as well as the name for each particular computer in the Group. Funny little story here, I was installing a small network of a half-dozen computers and a network laser in a medical office that deals with infectious diseases, so I used the obvious choice for the workgroup name - Infected. Well didn't the secretaries think that their machines had a virus on them when they saw Infected coming up in their Network Neighborhood folder! It's now got a different name...

To add some of the networking advantages such as file sharing and resource sharing, you must give the rights for others to use your resources. For example, you can Share your printer, but not your hard drive, but allow others to use your CD-ROM. By the same token, for others to share your resources, they must Map the resource so their own system can read it. Easiest way to do this is to open Explorer and select Tools and Map Network Drive. If you've been given the rights to do this, you can then map away. Likewise to add a printer which is local to someone else, you can go to the Add Printer Icon and install a Network Printer, then Browse the network for the particular printer you wish to add. From then on, you can select this printer as easily as if it were attached to your own computer. Obviously the computer it is attached to must be running! It is possible to have a network card in a printer, and then it becomes a node like any other device plugged into the hub.
