How to share file and printer in a computer network

How to share file and printer in a computer network:

Just because you have more than one computer doesn't mean you have to have a printer for each computer [Spector, Strohmeyer]. We will now show you how to share a printer between several computers on a network.

Before sharing your printer, you have to set up File and printer sharing. Here's how to set up File and printer sharing:

1. Click on Start in the bottom left corner of your screen. A popup list will appear.
2. Select Control Panel from the popup list. Type the word network in the search box.
3. Click on Network and Sharing Center.
4. Click on Change advanced shared settings, in the left pane.
5. Click on the down arrow, which will expand the network profile.
6. Select File and printer sharing and choose Turn on file and printer sharing.
7. Click on Save changes.

You're now ready to share your printer.

1. Click on Start in the bottom left corner of your screen. A popup list will appear.
2. Click on Devices and Printers, from the popup list.
3. Right click the printer you want to share. A dropdown list will appear.
4. Select Printer properties from the dropdown list.
5. Click on the Sharing tab
6. Select the Share this printer check box.

In order for other people to connect to the printer, they just have to add the network printer that you just opened for sharing to their computers. Here's how to do this.

What is an IP address?

WHAT IS A NETWORK IP ADDRESS?

Internet Protocol address (IP address)

Is a numerical label assigned to each device connected to a computer network that uses the Internet Protocol for communication. An IP address serves two principal functions: host or network interface identification and location addressing. It is also known as Network Address. Is a set of numbers, called as "octets" or "dotted decimal" notation, that identifies any network device. Its development began in 1974, led by computer scientists Bob Kahn and Vint Cerf. It is frequently used in conjunction with the Transmission Control Protocol, or TCP. Together they are referred to as TCP/IP.

      

IP VERSIONS

IPv4 (IP version 4)

Is the standard version defines an IP address as a 32-bit number. IPv4 addresses are canonically represented in dotted decimal notation, which consists of four decimal numbers, each ranging from 0 to 255, separated by dots.

IPv6 (IP version 6)

Is the advanced version  using 128 bits for the IP address.An IPv6 address is represented as eight groups offour hexadecimal digits, each group representing 16 bits (two octets, a group sometimes also called a hextet). The groups are separated by colons (:).

IP ADDRESS CLASSES

With an IPv4 IP address, there are five classes of available IP ranges: Class A, Class B, Class C, Class D and Class E, while only A, B, and C are commonly used. Each class allows for a range of valid IP addresses, shown in the following table.

Class A	1 to 126
Class B	128 to 191
Class C	192 to 223
Class D	224 to 239
Class E	240 to 255

127 – loopback function of a network

Class D – is for multicast

Class E – reserved for future or experimental purposes
