For Windows XP Step 1.Click Start->Control Panel->select and double click Network and internet connections (If you can´t find it, please go next) ->select and double click Network Connections. Step 2.Highlight and right-click the Local Area Connection icon; click on Status and go to General. Click the Properties button to open up the properties window. Step 3.Highlight the Internet Protocol (TCP/IP) tab, and then double click it or click Properties. The TCP/IP Properties window will display. Step 4.Now you have two ways to configure the TCP/IP protocol below: 1. Assigned by DHCP Sever Select Obtain an IP address automatically and Obtain DNS Server address automatically, as shown in the figure below. These may be selected by default. Then click OK to save setting. 2.Assigned manually 1) Select Use the following IP address, as shown in the following figure. If the router’s LAN IP address is 192.168.1.1, please type in IP address 192.168.1.x （x is from 2 to 253）, subnet mask 255.

What is subnetting? ISPs allocate IP address ranges to organizations based on the potential number of networks and hosts, or endpoints, that organizations require. Today, the allocations follow the Classless Inter-Domain Routing (CIDR) assignment method. The organization then subdivides the allocated address space into smaller allocations for each subnetwork within the organization, using a process called subnetting. The result of subnetting is the number of subnetworks increases, while the number of usable host IP addresses decreases. Each subnetwork is known as an IP subnet. Why use subnetting? Subnetting enables assigned network addresses to be broken into smaller, efficient allocations that are more suitable for each network within the organization. For example, a point-to-point WAN link between two routers only needs two addresses, while a LAN segment may need to support many hosts, such as servers, workstations, laptops and Wi-Fi-connected mobile devices.

       The scenario of this project can be referred to Figure 1. Figure 1 shows the logical network flow from  a home network to Cobham College facilities. In this figure, a Cobham College’s student is trying to  access the Online Learning system located in the Cobham College network facilities. The student is  using her modem to connect to the public network before able to connect to the Cobham College  facilities. From the Cobham College network, the data then was forwarded to IT Center where the  Online Learning System server is located. Figure 1: Logical Network Flow Links: Next Post

Layers of OSI Model(Progress 1) OSI stands for Open Systems Interconnection. It has been developed by ISO – ‘International Organization of Standardization‘, in the year 1984. It is a 7 layer architecture with each layer having specific functionality to perform. All these 7 layers work collaboratively to transmit the data from one person to another across the globe.  Physical Layer (Layer 1) : The lowest layer of the OSI reference model is the physical layer. It is responsible for the actual physical connection between the devices. The physical layer contains information in the form of bits. It is responsible for transmitting individual bits from one node to the next. When receiving data, this layer will get the signal received and convert it into 0s and 1s and send them to the Data Link layer, which will put the frame back together.  The functions of the physical layer are :   1. Bit synchronization: The physical layer provides the synchronization of the bits by providing a clock. This
