2. Internet Protocols
•A protocol is a set of rules. A letter sent through the
postal system also uses protocols. Part of the
protocol specifies where on the envelope the delivery
address needs to be written. If the delivery address is
written in the wrong place, the letter cannot be
delivered. Internet protocol works in a similar way.
Internet protocols are sets of rules governing
communication within and between computers on a
network. Protocol specifications define the format of
the messages to be exchanged.
3. Timing is crucial to network operation. Protocols
require messages to arrive within a certain amount of time
so that computers do not wait indefinitely for messages that
may have been lost. Therefore, systems maintain one or more
times during transmission of data. Protocols also initiate
alternative actions if the network does not meet the timing
rules. Many protocols consist of a suite of other protocols
that are stacked in layers. These layers depend on the
operation of the other layers in the suite to function
properly.
4. Assigning a static IP Address
•In a home network with several
computers and devices, it is ideal to
assign each of them a specific address.
This is for the purpose of avoiding
problems when you do troubleshooting
which requires figuring out the IP
address of each of them. It is also a
means to prevent address conflicts
between the devices. You can also
manage them with ease if you have
assigned their own addresses.
5. Here are the procedures in assigning an IP Address on a windows
base computer system:
1. Open the Control Panel’s Network Connections icon.
2. Open the icon representing your computer’s network connection.
3. Click the Properties button in the Status dialog box.
4. Fromthe list of items, choose Internet Protocol (TCP/IP).
6.
7. 5. Click the Properties button. The Internet Protocol (TCP/IP)
Properties dialog box appears.
8. 6. Type the IP address for your computer. Enter the appropriate IP
Address in the IP address section.
7. Type a subnet mask. The value usedon a local network is
commonly 255.255.255.0, but it can be different, such as
255.255.255.127.
8. Type the default gateway address. The default gateway is the router,
so type the router’s address. Figure 54 shows an example of assigning
an IP Address, Subnet mask and default gateway.
9.
10. 9. Type the address for the preferred DNS server. The address should be
obtained from your Internet Service Protocol. It is used to help your computer
find web pages and other addresses on the internet.
10. Type the address for the alternate DNS server.
The alternate Domain Name System(DNS) server’s IP address is something
that your ISP provides.
11. Click OK to confirm the settings.
12. Close all other open dialog boxes and windows.
