Question
Input the correct Layer of the OSI model with its function in the chart below. Each Layer will be used once and only once.
Layer
Purpose
Establishes a physical connection between computers on a network.
Decides how much data is to be sent at a time and controls the flow of data.
Primary location for switches operating.
Most commonly used in routing.
Where the operating system works.
Creates the session between the computers on a network.
Closest to end-user; this is where applications operate on the network.
2. The Data-Link Layer has six primary tasks. List each of these tasks and give a short description of each.
3. During data transmission, errors may occur; these errors come in three main types. What are the three main types of errors that can occur during transmission, and how are they different?

Explanation / Answer
Layer Purpose Physical layer Establishes a physical connection between computers on a network. Data Link Layer Decides how much data is to be sent at a time and controls the flow of data. Network Layer Primary location for switches operating. Transport Layer Most commonly used in routing. Session Layer Where the operating system works. Presentation Layer Creates the session between the computers on a network. Application Closest to end-user; this is where applications operate on the network.
