Basics
This term describes the physical layout of a network.
What is a topology?
This device connects multiple devices within the same network segment.
What is a switch?
This protocol is used to assign IP addresses dynamically.
What is DHCP?
This version of IP addressing uses 128-bit addresses.
What is IPv6?
This layer is responsible for the physical connection between devices.
What is the Physical Layer?
This type of network covers a small geographic area, like a home or office.
What is a Local Area Network (LAN)?
This device filters and forwards data packets between networks.
What is a router?
This protocol is used for transferring files between computers.
What is FTP?
This type of IP address is assigned permanently to a device.
What is a static IP address?
This layer is responsible for routing packets across networks.
What is the Network Layer?
This device connects multiple networks and directs data between them.
What is a router?
The layer of the OSI model at which a normal switch device operates.
What is the Data Link Layer?
This protocol is used to resolve domain names to IP addresses.
What is DNS?
This type of IP address can change each time a device connects to the network.
What is a dynamic IP address?
This layer ensures reliable data transfer and error recovery.
What is the Transport Layer?
This type of network covers a large geographic area, such as a city or country.
What is a Wide Area Network (WAN)?
A cable made of four pairs of twisted copper cables, and is less protected against noise than its counterpart.
What is an unshielded twisted pair cable?
The Ethernet protocol is used at this OSI model layer.
What is the Data Link Layer?
As Class A IP addresses are used for very large businesses, Class C IP addresses are used for this.
What are small networks, such as homes or offices with fewer than 250 people?
This layer translates data formats and encrypts data.
What is the Presentation Layer?
his term describes a network where each device can act as both a client and a server.
What is a peer-to-peer network?
This type of software (or dedicated hardware) is designed to detect and prevent unauthorized access to a network.
What is a firewall?
TCP and UDP are utilized at this layer of the OSI model.
1100 0000 . 1010 1000 . 0000 0000 . 0000 1011 when converted into its decimal equivalent, is this IP address.
What is 192.168.0.11?
This layer handles error detection and correction.
What is the Data Link Layer?
