1. What is the Internet? The Internet is a globally interconnected network of computers that, operating via several specific protocols, serves as a worldwide information system and provides the technological infrastructure on which countless applications are run (Leiner et al., 2012; Woods, 2013a). At the hub of every network is a server, with the Internet essentially being formed through the connection of multiple servers, encompassing all connected computers and creating a larger ‘inter-network’ (Woods, 2013b). Each device on the network has a unique numerical address and the Internet uses the DNS (Domain Name System) to allocate each a corresponding human-readable address (Woods, 2013a).
4. LAN-to-WAN • LAN-to-WAN Domain is where the IT Infrastructure links to a Wide Area Network (WAN) and the Internet. Responsible for applying the defined security controls to prevent unauthorized network access 5. WAN • Wide Area Network (WAN) Domain connects remote locations. Manages client’s firewalls and router configurations .The goal is to allow users the most access possible by making sure the data traveling in and out is safe 6.
What is the World Wide Web (WWW)? How was this developed The Internet is the actual network of networks where all the information resides. Things like Telnet, FTP, Internet gaming, Internet Relay Chat (IRC), and e-mail are all part of the Internet, but are not part of the World Wide Web. The Hyper-Text Transfer Protocol (HTTP) is the method used to transfer Web pages to your computer. With hypertext, a word or phrase can contain a link to another Web site.
The __________________ tool provides a central access point for all of the network controls and connections on a computer running Windows 7. Network and Sharing Center 3. A device that connects one network to another is called a __________________. router 4. The most common method for illustrating the operations of a networking stack is the __________________, which consists of __________________ layers.
TCP is the transport layer protocol that links the application layer to the network layer. TCP breaks the data into smaller packets, numbers the packets, ensures each packet is reliably delivered, and puts the packets in the proper order at the destination. IP is the network layer protocol and performs addressing and routing. IP software is used at each of the computers through which the message passes through; IP routes the message to the final destination. TCP/IP is the transport & network layer protocol used on the Internet.
Unit 1 IP Addresses Classes and Special-Use IP Address Space Network IDs used to be divided into classes, and these classes are Class A, B, and C. These classes were allowed to have a range of addresses depending subnet we are using. This class-based system would work well for a while, but with the rapid growth of the Internet it became evident that this addressing scheme had to be changed in order to support the many networks that were being created (CompTIA Network, Ch.7, 2009). This 32-bit IP addressing system is subdivided into two portions: the network address space and the host address space in IPv4. Class A were created for a very large network with few logical network segments and many hosts that have the high-order bit set to zero. The first octet (the left-most eight bits) is used to define the network ID.

These classes were allowed to have a range of addresses. This class-based system would work well for a while, but the rapid growth of the Internet it becomes evident that this addressing scheme had to be changed in order to support the many networks that were being created. A class full system would be created and still used the IP addressing fundament of a classless system. This 32-bit IP addressing system is subdivided into two portions; the network address space are the host address space. Class A addresses were created for a very large network with few logical network segments and many hosts that have the high-order bit set to zero.
What are the advantages of organizing the functions of th OSI module into layers? helps network designer and troubleshooting. 5. What functions resides under the applicaion layer? Resource sharing and device redirection Remote file access Remote printer access Inter-process communication Network management Directory services Electronic messaging (such as mail) Network virtual terminals 7.What functions resides under the transport layer?
Once the network has been fixed, all of the computers on the network will be able to transfer and communicate information back and forth. That’s why a communication protocol is very important. Traffic analysis is defined as the process of gathering information from the features of communication traffic other than its contents, such as timing and size. Traffic analysis can be utilized on any type of network. When using traffic analysis, this process reveals the amount, type, origin and destination of the traffic flow on a network.
C. two PCs, with one cabled to a router Ethernet port with a crossover cable and the other PC cabled to another router Ethernet port with a crossover cable. 7. A. hubs create a single electrical bus to which all devices connect, causing the devices to share the bandwidth. C. hubs allow collisions to occur when two attached devices send data at the same time. 8.
