OSI Model Layers
TCP and UDP protocols both exist at this layer.
What is Layer 4 or the Transport layer?
This item requires more memory, processor power and storage than the hosts that connect to it.
What is a server?
The name for software embedded in hardware that allows it to perform its function.
What is firmware?
The mail protocol is used to send mail messages to a server.
What is IMAP4?
The Application layer protocol used to monitor and gather information about network traffic.
What is SNMP?
The Data Link Layer utilizes this name for its protocol data unit (PDU).
What is a frame?
This item is typically the first thing a host computer is connected to in a local area network.
What is a switch?
In this physical topology, devices are daisy-chained together in a single line.
What is a bus?
This happens when a message is too large to transport on a network.
What is he message is divided into smaller messages called segments or datagrams?
The most popular web server application.
What is Apache?
This layer is responsible for reformatting, compressing, and/or encrypting data in a way that the application on the receiving end can read.
What is the Presentation layer?
The item that provides a network connection on a piece of equipment such as a PC.
What is a NIC?
In this physical topology, all connected devices connect to one central device, such as a switch.
What is a star?
This protocol is considered to connection-oriented and guarantees packet delivery.
What is TCP?
The hardware address for a network interface.
What is a MAC address?
This OSI model describes how data between applications is synced and recovered if messages don't arrive intact at the receiving application.
What is the session layer?
This item typically connects a LAN to a WAN.
What is a router?
Network switches typically operate at this OSI model layer.
What is Layer 2?
This network model is not considered to be easily scalable.
What is peer-to-peer?
In the TCP/IP model, this layer combines the responsibilities of the Application, Presentation, and Session layers from the OSI model.
What is the Application layer?
HTTP, IMAP4, FTP, and Telnet are all examples of protocols that operate at what layer of the OSI model?
What is Layer 7 - Application?
This terms refers to the addition of a header to data inherited from the layer above in the OSI model.
What is encapsulation?
IP, ICMP, and ARP protocols operate at this OSI model layer.
What is Layer 3?
Assigned to each node on a network, it's used by the Network layer to uniquely identify the node.
What is an IP address?
