| A | B |
| Layer of OSI model that TCP operates | Layer 4 |
| Orderly initiation, termination, and managing of communication | Dialogue Separation |
| Loyer of the OSI model responsible for presenting data where devices understand it | Presentation |
| Type of communication used when two messages can cross during a conversation | Two-way simultaneous |
| Term used when sound files are downloaded while playing | Streaming audio |
| Sequence that synchronizes a connection at both ends | Three-way handshake |
| Type of connection that describes Transmission Control Protocol | Connection-oriented |
| What happens if a sequence number is missing with TCP | Re-transmission |
| NFS is a protocol of what layer | Five |
| What layer is responsible for data encryption | Layer 6 |
| File format that acts as directons to tell web browser how to display documents | HTML |
| Layer of OSI model responsible for file compression | Presentation |
| Two file formats use to display still images | GIF and JPEG |
| Field of a TCP segment that defines the number of octets a recipient is willing to accept | Window |
| Layer responsible for transition between different types of code | Layer 6 |
| The amount of data that can be transmitted before receiving an acknowledgement | Window size |
| Layer that establishes, manages, and terminates sessions between applications | Session layer |
| Communication that avoids interrupts by taking turns | Two-way alternate |
| When the session layer decides whether to use two-way simultaneous or alternate | Dialogue control |
