Configuring network connections In this lab I will be explaining how to use the network and sharing center, enabling network map, manually configuring TCP/IP, testing network connections and networking. 3.1 To begin with this lab I will have to open my Virtual Machine and go into its settings to change network adapter to bridged. It also show me how to go into my network through the control panel. It shows me how to go into the advanced sharing settings. 3.2 In this part of the lab

They translate domain names into IP (Internet Protocol) addresses. Domain names are easier for people to remember, computers access the internet based on IP addresses. Dynamic Host Configuration Protocol (DHCP) is a network protocol that allows a server to automatically assign an IP address to a computer. Now that we have defined these two terms it is possible to analyze the cost effectiveness of a DHCP server. To manually configure a computer workstation with an IP address is not difficult. On

the first number in the IP address. The total number of IPv4 addresses is 4, 294, 967,296. Address type: Unicast, multicast, and broadcast. IPv4 expressed in dotted decimal notation. The new concepts and new implementation of old concepts in IPv6 include the following: * Larger address space (128-bit vs. 32-bit) * Autoconfiguration of Internet-accessible addresses with or without DHCP (without DHCP it’s called stateless autoconfiguration) * More efficient IP header (fewer fields and

VPN Concepts A virtual private network (VPN) is used to transport data from a private network to another private network over a public network, such as the Internet, using encryption to keep the data confidential. In other words, a VPN is an encrypted connection between private networks over a public network, most often the Internet. VPNs provide the following services: Confidentiality: VPNs prevent anyone in the middle of the Internet from being able to read the data. The Internet is inherently

II. Introduction What is the so called Closed-Circuit Television (CCTV)? What is the purpose of installing CCTV cameras in the school, store, and even in the house? What are the benefits that we can get in using this device? Will it give us an assurance of perfect security that will make us feel safe? These cameras have also changed over the years. They were once large white boxes that could not zoom in or out or follow objects closely. Today they can be small in size and hidden not to be noticed

Network addresses were originally defined by the internet the Internet community in five address classes. These classes were defined in order to accommodate networks of varying sizes. TCP/IP supports class A, B, and C addresses assigned to hosts. These classes define which bits are used for the network ID and which bits are used for the host ID. It also defines the possible number of networks and the number of hosts per network. Class A addresses are assigned to networks that have a very high number
