DO IT NOW IN SILENCE DO IT NOW IN SILENCE Answer these questions in your booklet in full sentences! Answer these questions in your booklet in full sentences! Which CPU register holds memory to be used? A) MRD B) MAR C) ALU A NIC is? A) B) C) A Network Interference Card A Network Interface Card A Network Interaction Card What frequencies can Wi-Fi operate on? Wi-Fi operates on 2.4Ghz and 5.0Ghz Explain why fibre optic is the fastest method of transmission? Because fibre optic uses light and light is one of the fastest things in the universe. STRETCH How can the different materials affect Wi-Fi usage? Due Wi-Fi being a radio wave copper and lead etc. can absorb the radiation and then stop it from reaching its destination.

We Are Learning To- To understand the similarities and differences between the OSI and TCP/IP Model What I m Looking For: Define the purpose of the term protocol Describe the process of the OSI and TCP/IP Model Explain the differences between the OSI and TCP/IP Model Careers Focus Network Manager
OSI Model OSI Model We Are Learning To- To understand the similarities and differences between the OSI and TCP/IP Model OSI Model- Stands for Open Systems Interconnection Model. It is used to understanding data communications between any two networked system. There are seven layers in the OSI model. They are as follows: OSI MODEL Application Presentation Session Transport Network Data Link Physical What I m Looking For: Define the purpose of the term protocol Describe the process of the OSI and TCP/IP Model Explain the differences between the OSI and TCP/IP Model Careers Focus Back End Developer
TCP/IP Model TCP/IP Model We Are Learning To- To understand the similarities and differences between the OSI and TCP/IP Model TCP/IP Model- stands for Transmission Control Protocol/Internet Protocol Model. There are four layers in the TCP/IP Model. They are as follows: TCP / IP MODEL What I m Looking For: Define the purpose of the term protocol Application Describe the process of the OSI and TCP/IP Model Transport Explain the differences between the OSI and TCP/IP Model Internet Careers Focus Back End Developer Network Access
OSI VS TCP / IP OSI VS TCP / IP We Are Learning To- To understand the similarities and differences between the OSI and TCP/IP Model OSI MODEL TCP / IP MODEL Application Layer 7 Application Layer 4 What I m Looking For: Define the purpose of the term protocol Presentation Layer 6 Session Layer 5 Transport Layer 3 Transport Layer 4 Describe the process of the OSI and TCP/IP Model Internet Network Layer 3 Layer 2 Explain the differences between the OSI and TCP/IP Model Data Link Layer 2 Network Access Layer 1 Physical Layer 1 Careers Focus Back End Developer
OSI Model OSI Model Layer 1 (Physical) Layer 1 (Physical) We Are Learning To- To understand the similarities and differences between the OSI and TCP/IP Model Physical layer is responsible for transmitting bits over the physical cable. What I m Looking For: Define the purpose of the term protocol Functions Data Encoding Transmissions of bits Describe the process of the OSI and TCP/IP Model Explain the differences between the OSI and TCP/IP Model Careers Focus Back End Developer
OSI Model OSI Model Layer 2 (Data Link) Layer 2 (Data Link) We Are Learning To- To understand the similarities and differences between the OSI and TCP/IP Model Data Link Layer is responsible for controlling the error between adjacent nodes and transfer the frames to other computers via the physical layer. What I m Looking For: Define the purpose of the term protocol Functions Link establishment and termination Frame Traffic control Describe the process of the OSI and TCP/IP Model Explain the differences between the OSI and TCP/IP Model Careers Focus Back End Developer
OSI Model OSI Model Layer 3 (Network) Layer 3 (Network) We Are Learning To- To understand the similarities and differences between the OSI and TCP/IP Model The network layer is responsible for translating the logical network address and names into their physical address What I m Looking For: Define the purpose of the term protocol Functions Traffic control Logical to physical address mapping Describe the process of the OSI and TCP/IP Model Explain the differences between the OSI and TCP/IP Model Careers Focus Back End Developer
OSI Model OSI Model Layer 4 (Transport) Layer 4 (Transport) We Are Learning To- To understand the similarities and differences between the OSI and TCP/IP Model The transport layer is responsible for sending messages between the hosts. What I m Looking For: Define the purpose of the term protocol Functions Delivering messages Session multiplexing Describe the process of the OSI and TCP/IP Model Explain the differences between the OSI and TCP/IP Model Multiplexing This is when we use differing data signal frequencies down one cable so multiple pieces can be sent only using one cable.
