Capstone Review
Topic 1 – INPUT/OUTPUT
Level 1 – Definition
1. A person wishes to purchase a personal computer for home usage. Identify the internal hardware components this computer should contain.
a. Student should identify the following: Power Supply, Motherboard, CPU, RAM,
HDD, USB ports for I/O’s such as mouse and keyboard. You also can add in
DVD drives, I/O’s for speakers, monitor, and microphone.
Level 2 – Application
2. Explain in simple terms the I/O process.
a. “Input/Output”… Data is entered into the computer through an input device such as a mouse or keyboard; given the application used the CPU will process the data into output.
Level 3 – Troubleshooting
3. You typed “abcd” but the locally attached printer prints garbled text. How do you go about resolving this issue?
a. This may be a communication error most likely with a corrupted or incorrect driver. The student should detail the process of how to isolate the driver via update, remove, install, etc.
Topic 2 – OSI MODEL
Level 1 – Definition
1. What is the OSI model?
a. A brief explanation of the main purpose of the model: (Standardize the communication flow among various technologies and products by different manufactures). The 7 layers are: 7 Application, 6 Presentation, 5 Session, 4
Transport, 3 Network, 2 Data Link, and 1 Physical.
Level 2 – Application
2. Use the OSI model to explain how an email message from you gets read by the recipient on his/her computer.
a. The satisfactory answer would demonstrate how the message is initiated from the computer, passed down the 7 layers, and how it is modified in each layer.
The student should include how the modified message is transmitted, received by the recipient’s computer and reconstructed.
Level 3 – Troubleshooting
3. A user reports that they cannot download a file from the internet. Using the OSI model, what are some of the questions a NSA may ask to troubleshoot this problem?
a. Is the network cable plugged in?
b. Does the PC in question have a valid IP address?
