Computer Networking Quiz

A hardware address that is permanently associated with each network interface card (NIC) and is unique in the world.

A logical address that is used to identify a device on a network.

The maximum size of an Ethernet frame that can be sent over a network.

The port number that is used to identify a specific service or application on a device.

A set of rules that define how data is exchanged between devices on a network.

The set of security requirements that ensure that data is protected from unauthorized access, modification, or disclosure.

A group of devices that are connected to the same network and can communicate directly with each other.

A device that connects devices to a network and forwards data between them.

A set of multiple paths between a sender and receiver which allows the network to function even if some paths fail.

A message sent by a device to discover the MAC address of another device on the same network.

The network address of a device, which is determined by its IP address and subnet mask. It's like the building number of a host on the network.

The process of determining the MAC address of a device on a network based on its IP address.

The number of bits that make up an IPv4 address.

The process of exchanging messages to establish a connection between two hosts.

The amount of data that can be stored in an Ethernet frame before it is sent over the network.

A standard set of rules that governs communication between devices on a network. This ensures devices can understand and exchange information.

The process of identifying devices on a network based on their physical address. This allows devices to find each other on the network.

The process of sending and receiving data from a network. This involves establishing connections and transferring data between devices.

This is a security measure that allows only specific devices access to the network. Often used for visitors or temporary connections.

A method for connecting to the internet using a mobile device's own cellular network. This provides internet access even without Wi-Fi.

Specific configuration that allows the network to be refreshed and re-configured. This can fix some network connection issues.

Provides internet, television, and phone services on the same network using existing cable infrastructure.

Uses existing telephone lines to deliver high-speed internet, enabling an always-on connection.

A network model where devices share resources and act as both clients and servers, eliminating the need for dedicated servers.

The latest internet addressing system offering a larger address space and a more efficient routing mechanism.

An attack that exploits the Address Resolution Protocol (ARP) by sending forged ARP messages to associate an attacker's MAC address with a victim's IP address.

A network protocol that translates IP addresses (logical addresses) into MAC addresses (physical addresses).

The process of dividing a network into smaller subnetworks (subnets) to improve efficiency, security, and reduce broadcast traffic.

A protocol that automatically assigns IP addresses to devices on a network, simplifying administration and reducing configuration errors.

A configuration mode in Cisco IOS that allows you to configure global settings for the device.

A configuration mode in Cisco IOS where you can execute basic commands and manage the device.

A private IP address is assigned to a device on a private network and is not routable over the public internet.

IPv6 addresses are represented using a colon-separated sequence of hexadecimal numbers.

A static route is manually configured by a network administrator and does not change automatically.

The SSID is the name of a wireless network that clients can see and connect to.

IMAP allows email clients to access and manage email messages stored on a mail server without downloading them to the client.

Data Link layer prepares data packets for transmission over a physical network. It adds information like addresses and error checking to ensure reliable communication.

A high-speed communication technology that transmits data using light pulses through thin glass fibers, offering high bandwidth and low signal degradation.

The total number of bits or pieces of information that can be transmitted over a network connection during a specific period.

The measure of time it takes for a signal to travel from a sender to a receiver and back again, highlighting the speed and efficiency of communication.

A communication protocol that defines how devices send and receive data packets over the network.

The primary organization responsible for the global distribution of IP addresses, ensuring a unique address space for all devices connected to the internet.
