Networking Flashcards
What is computer networking?
Computer networking involves connecting computers and other devices to share resources information and services.
Define a protocol in the context of networking.
A protocol is a set of rules that govern the format and behavior of communication between devices in a network.
What is the purpose of an IP address?
An IP address (Internet Protocol address) is used to uniquely identify a device on a network and facilitate communication between devices.
Explain the difference between IPv4 and IPv6.
IPv4 and IPv6 are versions of the Internet Protocol. IPv4 uses 32-bit addresses while IPv6 uses 128-bit addresses allowing for a larger number of unique addresses to support the growing number of devices on the internet.
What is the OSI model?
The OSI (Open Systems Interconnection) model is a conceptual framework that standardizes the functions of a telecommunication or computing system into seven abstraction layers.
Describe the role of a router in a network.
A router is a networking device that forwards data packets between computer networks. It connects different networks and directs data traffic efficiently.
What is a subnet mask?
A subnet mask is a 32-bit number that divides an IP address into network and host portions helping to identify the network a device belongs to.
Explain the purpose of DNS (Domain Name System).
DNS translates human-readable domain names into IP addresses facilitating the identification of resources on a network.
What is a firewall?
A firewall is a network security device that monitors and controls incoming and outgoing network traffic based on predetermined security rules.
Define bandwidth in the context of networking.
Bandwidth refers to the maximum rate of data transfer across a network and is often measured in bits per second (bps).
