What is network topology?

Network topology refers to the arrangement of different elements (links, nodes, etc.) in a computer network.

What are the common types of network topologies?

The common types of network topologies include star, ring, bus, mesh, and hybrid.

What is a star topology?

In a star topology, all nodes are connected to a central hub or switch, which acts as a repeater for data flow.

What is a ring topology?

In a ring topology, each node is connected to two other nodes, forming a circular pathway for data.

What is a bus topology?

In a bus topology, all devices share a single communication line or cable.

What is a mesh topology?

In a mesh topology, each node is connected to multiple other nodes, providing multiple pathways for data.

What is a hybrid topology?

A hybrid topology combines two or more different types of topologies.

What is a network protocol?

A network protocol is a set of rules and conventions for communication between network devices.

What are some common network protocols?

Common network protocols include TCP/IP, HTTP, FTP, and SMTP.

TCP/IP (Transmission Control Protocol/Internet Protocol) is the fundamental suite of protocols that governs the internet.

HTTP (Hypertext Transfer Protocol) is the protocol used for transferring web pages on the internet.

FTP (File Transfer Protocol) is a standard network protocol used to transfer files from one host to another.

SMTP (Simple Mail Transfer Protocol) is a protocol used for sending emails.

What is an IP address?

An IP address is a unique identifier for a device on a network, allowing it to communicate with other devices.

What is the difference between IPv4 and IPv6?

IPv4 uses a 32-bit address scheme allowing for about 4.3 billion addresses, while IPv6 uses a 128-bit address scheme allowing for a vastly larger number of addresses.

A subnet is a segmented piece of a larger network, allowing for better management and security.

A router is a device that forwards data packets between computer networks, directing traffic on the internet.

A switch is a networking device that connects devices within a LAN and uses MAC addresses to forward data to the correct destination.

A firewall is a network security device that monitors and controls incoming and outgoing network traffic based on predetermined security rules.

What is network security?

Network security is the practice of protecting a computer network from intruders, whether targeted attackers or opportunistic malware.

What are some common network security measures?

Common network security measures include firewalls, intrusion detection systems, and encryption.

Encryption is the process of converting information or data into a code to prevent unauthorized access.

A VPN (Virtual Private Network) is a service that creates a secure connection over the internet, allowing users to send and receive data as if their devices were directly connected to a private network.

Bandwidth is the maximum rate of data transfer across a network path, often measured in bits per second.

Latency is the time it takes for data to travel from the source to the destination, often measured in milliseconds.

What is a network administrator?

A network administrator is responsible for managing and maintaining computer networks, ensuring their reliability and security.

What is network monitoring?

Network monitoring is the process of continuously observing a computer network for any issues or performance problems.

What is a network diagram?

A network diagram is a visual representation of a computer network, showing the devices and their connections.

What is cloud computing?

Cloud computing is the delivery of computing services over the internet, allowing for on-demand access to resources.

What are the types of cloud services?

The main types of cloud services include Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS).

IaaS (Infrastructure as a Service) provides virtualized computing resources over the internet.

PaaS (Platform as a Service) provides a platform allowing customers to develop, run, and manage applications without the complexity of building and maintaining the infrastructure.

SaaS (Software as a Service) delivers software applications over the internet, on a subscription basis.

What is the Internet of Things (IoT)?

The Internet of Things (IoT) refers to the interconnection of everyday devices to the internet, allowing them to send and receive data.

What is a network interface card (NIC)?

A NIC is a hardware component that allows a device to connect to a network.

A modem is a device that modulates and demodulates signals for data transmission over telephone lines or cable systems.

What is a proxy server?

A proxy server is an intermediary server that separates end users from the websites they browse.

What is network virtualization?

Network virtualization is the process of combining hardware and software network resources into a single, software-based administrative entity.

What is a data packet?

A data packet is a formatted unit of data carried by a packet-switched network.

What is Quality of Service (QoS)?

Quality of Service (QoS) refers to the overall performance of a network, particularly in terms of its transmission quality and service availability.

What is a network topology diagram?

A network topology diagram visually represents the layout of a network, including devices and their connections.

What is a network switch?

A network switch is a device that connects devices on a computer network and uses packet switching to forward data to its destination.

What is a network cable?

A network cable is a cable used to connect devices in a network, allowing for data transmission.

What is a wireless network?

A wireless network is a network that uses radio waves to connect devices without physical cables.
