SUBNETTING CALCULATION

Assume Utem Network is Class B (172.16.0.0)      Class B subnet default mask is 255.255.0.0 or 11111111.11111111.0.0      We have 10 faculty and 1 IT Centre, therefore there need to be at least 11 subnets. 2^4 = 16. 4  bits will be borrowed from the host id.        Mask after subnetting will be 11111111.11111111.11110000.00000000 or 255.255.240.0/20        Using formula 2^h-2 = 2^4-2 = 14        Table List of IP Address Subnet Network address Usable address Broadcast address 0 172.16.0.0/20 172.16.1.0/20 to 172.16.14.0/20 172.16.15.0/20 1 172.16.16.0/20 172.16.17.0/20 to 172.16.30.0/20 172.16.31.0/20 2 172.16.32.0/20 172.16.33.0/20 to 172.16.46.0/20 172.16.47.0/20 3 172.16.48.0/20 172.16.49.0/20 to 172.16.62.0/20 172.16.63.0/20 4 172.16.64.0/20 172.1

OSI LAYER MODEL

Image
  OSI or Open System Interconnection layer model is a model created by International Standardization of Organization (ISO) for communication system to communicate with a standard protocol. When the student uses their computer to access Ulearn System, the data flows from application layer, presentation, session, transport, network, data link and physical layer.   Application layer The application layer is responsible for providing service to the user. It is used by the end user software which is for example the web browser. It provides protocol that allow the browser to send and receive information and present meaningful data to user. Protocol example are Hypertext Transfer Protocol (HTTP) and File Transfer Protocol (FTP).   Presentation layer             The presentation layer is responsible for the syntax and semantics of the information exchanged between two systems.  It defines how two devices should encode, encrypt, and compress data so it is received correctly on the other end.
