What is network topology?
The physical and logical layout of how devices are connected within a network, defining their arrangement and interconnection for data flow.
Why is network topology important?
It impacts network performance, scalability, and reliability.
What is Star topology?
Devices are connected to a central hub or switch. Easy to manage and scales well.
What is Mesh topology?
Every device is directly connected to each other, providing high redundancy and reliability.
What is Point-to-Point topology?
A direct connection between two devices.
What is Bus topology?
A single backbone cable connects all devices.
What is Ring topology?
Devices are connected in a circular manner, each linking to two others.
What is Tree topology?
A hybrid of star and bus, where groups of star networks are connected hierarchically.
What is a Switch?
Devices that connect multiple devices on a local network and manage data traffic between them. Use example: Used in office networks to connect computers, printers, and other devices.
What is Routers?
Hardware that routes data between networks, typically connecting a local network to the internet. Use example: Used in homes and businesses to provide internet access and route traffic.
What is Modem?
A device that converts digital signals from a computer into analog signals for internet connection and vice versa. Use example: Used by internet service providers to connect customers to the internet.
What is Network Interface Card (NIC)?
A component that allows devices to connect to a network, typically through an Ethernet cable or Wi-Fi. Use example: Installed in computers, printers, and smartphones to allow network access.
What is virtual local area network (VLAN)?
A logical grouping of devices within a LAN, segmented to improve traffic management and security.
What is virtual private network (VPN)?
A secure connection method that allows users to send data securely over public networks, often used to connect remote workers to a company network.
What is wide area network (WAN)?
A network that covers a large geographic area, connecting LANs across cities, countries, or even continents.
what is a server
computer systems that provide resources, data, or services to other computers (clients) over a network
What is satellite network?
A type of network that uses satellites to provide internet or communication services, especially in remote areas.
What is cellular network?
A wireless network used for mobile communication, connecting mobile devices through cell towers.
What is transmission media?
Transmission media refers to the physical or logical pathways through which data travels within a network.
What is wired communication?
Wired communication relies on physical cables, such as coaxial cables, fiber-optic cables, and twisted-pair wires, to transmit data. It provides high-speed and reliable connections with minimal interference but requires extensive infrastructure and lacks flexibility.
What is wireless communication?
Wireless communication transmits data using radio waves, microwaves, or infrared signals, eliminating the need for physical cables. It offers greater mobility and flexibility, useful for mobile devices and remote access, but is more susceptible to interference and often has lower transmission speeds compared to wired connections.
What is OSI model?
The Open Systems Interconnection (OSI) model is used to describe how various networking protocols interact at different layers.
What is HTTP?
HTTP (Hypertext Transfer Protocol) is used for transferring web pages and data on the internet. For example, when you access a website, HTTP retrieves and displays the content in your browser.
What is SMTP?
SMTP (Simple Mail Transfer Protocol) facilitates the sending of emails between servers. It is used for email delivery from one server to another.
