5.2 Extranet Diagram

My company would use the extranet to communicate with our supplier to get the materials when needed. We would set up a firewall so that other people outside of the company cannot access our VPN. The VPN would protect our information from other people who can access the internet. we would then be able to communicate with our suppliers without any outside interference.

4.3 Packet-Switching

This image shows how the router sends off data from A and B converts it into packets and sends it out to C and D. The router uses the client to request the work and the server does all the work. While requesting the work the router creates a peer network between each of the routers. The IP then determines the size of the packets. TCP then checks the packets for errors or duplicates. The IP then delivers the packets to the appropriate routers.  Everything explained in the diagram is packet-switching technology.

5.3 Intranet Achitectural Diagram

    This diagram shows how an intranet works within a corporation.  Inside the "intranet" block, the client  inside the network sends information through the corporate server, through the firewall, and over the internet to the client outside the LAN.  The client can now see the information sent using an intranet.

4.2 A Basic Network

This graph displays a Client-Server Relationship or a Server Centric Relationship.  The connection you see is the transmission medium.  Bandwidth is the amount of data that can be sent over a connection.  The connection can be through wireless media or cable media.  There are protocols, or rules of the relationship, to make sure everything runs smoothly.

4.1 IFS H/W Infrastructure

This image shows how we use input technologies, such as keyboards and mouses, to input letters into the system unit.  The unit then uses processing technologies to convert the letters into binary code, or machine language, so that the CPU can then interpret it.  The CPU uses bytes, which are composed of 8 bits, to understand each letter.  The ALU then calculates the bits into ASCII, which is the language that we understand.  Then the results of the calculations are stored in the control unit and are visible through output technologies.
