More OSI Model
100

This networking model has seven layers and includes layers such as Physical, Data Link, and Application

OSI Model

100

This transport protocol is connection-oriented and guarantees data delivery by requiring acknowledgments from the receiving host.

TCP

100

This 48-bit unique identifier is assigned to a device’s NIC by the manufacturer and helps identify devices on a LAN.

MAC address

100

This version of IP uses 32 bits and is typically written in dotted decimal format like 192.168.1.1.

IPv4

100

This is the number of layers in the OSI Model.

7

200

In the OSI model, this layer deals with transmitting bits over cables or airwaves

Physical Layer

200

This transport protocol is connectionless, offers minimal overhead, and does not guarantee the delivery or order of packets.

UDP

200

The first half of a MAC address identifies the manufacturer and is known by this three-letter abbreviation.

OUI

200

MAC addresses work at this OSI model layer, while IP addresses work at the network layer

Data Link Layer

200

This layer of the OSI Model is responsible for delivering data packets based on IP addresses.

Network Layer

300

In the TCP/IP model, this layer corresponds to both the Physical and Data Link layers of the OSI model

Network Access Layer

300

Applications like video streaming and online gaming often prefer this protocol because speed is more important than perfect accuracy.

UDP

300

Each hexadecimal digit represents how many binary bits?

Four

300

This command-line tool can be used to find both the MAC address and the IP address on a Windows computer.

ipconfig

300

Encryption and decryption of data occur at this OSI layer.

Presentation Layer

400

This process involves adding headers and trailers to data as it moves through the layers to prepare it for transmission.

encapsulation

400

This application layer protocol translates human-readable domain names into IP addresses.

DNS

400

MAC addresses are typically written in this format, using either hyphens or colons to separate six pairs of digits.

Hexadecimal

400

This protocol maps an IP address to a MAC address on a local network.

ARP

400

The physical connection between devices, including cables and switches, is handled at this OSI layer.

Physical Layer

500

In networking, this is the name for a single unit of information transmitted over a network, including both data and protocol-specific information.

Protocol Data Unit or PDU

500

This default logical port is used for secure web traffic over HTTPS.

443

500

In hexadecimal, this digit immediately follows the number 9.

A

500

This type of IP address, created to solve the shortage of available addresses, uses 128 bits and allows abbreviation by replacing consecutive zeros with a double colon.

IPv6

500

TCP and UDP operate at this OSI layer to manage data transmission between hosts.
