A computer network is a collection of interconnected devices that can communicate with each other and share resources.
What are the advantages of using a computer network?
Advantages of using a computer network include resource sharing, improved communication, centralized data storage, and cost savings.
What is a LAN?
A LAN (Local Area Network) is a computer network that covers a small geographic area, such as a home, office, or school.
What is a WAN?
A WAN (Wide Area Network) is a computer network that covers a large geographic area, such as multiple cities or countries.
What is the purpose of a router in a computer network?
The purpose of a router is to forward data packets between different computer networks.
What is a firewall in the context of computer networks?
A firewall is a network security device that monitors and controls incoming and outgoing network traffic based on predetermined security rules.
What is the difference between a wired and wireless network?
A wired network uses physical cables to connect devices, while a wireless network uses radio waves or infrared signals.
What is a protocol in computer networks?
A protocol is a set of rules and conventions that govern the communication between devices in a network.
What is the role of an IP address in computer networks?
An IP address is a unique identifier assigned to each device connected to a computer network, allowing them to communicate with each other.
What is the difference between IPv4 and IPv6?
IPv4 uses 32-bit addresses, while IPv6 uses 128-bit addresses, allowing for a much larger number of possible addresses.
What is the purpose of DNS in computer networks?
DNS (Domain Name System) is used to translate domain names (e.g., google.com) into IP addresses, allowing users to access websites by their domain names.
What is a subnet mask?
A subnet mask is a 32-bit number used in conjunction with an IP address to determine the network and host portions of the address.
What is the purpose of a switch in a computer network?
A switch is a network device that connects multiple devices within a LAN, allowing them to communicate with each other efficiently.
What is a proxy server in computer networks?
A proxy server acts as an intermediary between client devices and other servers, providing various functionalities such as caching, security, and anonymity.
What is the purpose of NAT in computer networks?
NAT (Network Address Translation) allows multiple devices in a private network to share a single, unique IP address for communication with external networks.
