This week you will be introduced to the basic concepts of Computer Networks and what it means to live in a network-centric world. We will examine the elements that make up a computer network and the characteristics of the underlying network architecture. Different network topologies will also be explored.

This week we will examine the process of Data Encapsulation within the context of both the OSI and TCP/IP data models. We will explore how the network protocols work together to get the data across the Internetwork to the right destination network, device, and application. We will also look at the Ethernet standard and its implementation.

This week we will examine the role of the switch in computer networks and its basic functions. We will also take an indepth look at the Address Resolution Protocol (ARP).

This week we will examine the basic features of the Cisco IOS. You will learn how to navigate the IOS and how to configure network devices. You will be able to limit access to these devices and congfigure host devices. Finally you will be able to verify connectivity between two host devices.

This week we will examine the function of the network layer and the role of IP at this layer.

This week we will discuss the relevance of Subnetting, VLSM, DHCP and NAT in IPv4 networks.

This week you we will explore the Transport layer in detail with particular emphasis on Transport Control Protocol (TCP) and User Datagram Protocol (UDP). We will also look at the Internet Control Message Protocol (ICMP).

This week you will be introduced to the fundamentals of Routing and Routing Protocols. The structure of routing tables will be examined and configuration of both static, default and dynamic routes will be implemented.
