what does WAN stand for and mean?
Wide Area Network- a network that connects devices over large distances like between cities or countries
What is a pro of a bus topology?
It is a simple and cost- effective design
It requires less cabling network setup
Adding more devices is a simple process in the bus structure
Network- a group of computers or devices connected together to share info and resources
What is a computer network, and how does it impact my daily life?
A computer network is a system that connects two or more computing devices so they can share data, hardware, and resources
What is a short name for a point to point topology?
P2P
what is a domain name system?
Domain Name System- a system that translates website names like google.com into IP addresses so you can visit websites easily
what is a con of a star topology?
- everything on a star topology depends on the central hub
If the centralized system fails the entire network is affected
- it needs more cables then other topologies
what is a router?
Router- a device that sends data between different networks and directs it to the correct destination
How does data move across a network?
Data is transferred through a network by breaking information into small pieces called packets, sending them across physical or wireless paths, and reassembling them at the destination
A Folder / Sub-Folder could also be described as a?
Parent / Child
What is a firewall?
Firewall- a security tool that helps protect a network by blocking unauthorized access
what is a pro of a mesh topology?
The data has multiple paths the network remains operational even if there is a failure in the area
It is an easily scalable topology scalability increases the network path and as a result the performance of the network
The data transfer rates and performance are very high
what is a switch?
switch - a device that connects multiple devices within the same network helping them communicate with each
Why does every device need an IP address?
Every device needs an Internet Protocol (IP) address so data can find its exact destination across a network
What is a .zip file?
A file or files that has been compressed to make a smaller file.
What is ping?
Ping- a command used to test if a device is connected to a network and how long it takes data to travel between devices
what are the cons of a hybrid topology?
Combined topologies get complex to manage and maintain
The cost is higher than the simple topologies

what is a modem?
modem- a device that connects a network to the internet to the internet by converting signals between digital devices and the internet service provider other
Why is network security important, and how can we protect ourselves online?
What does the term “local storage” refer to?
Storage on the physical device being used
What is ethernet?
Ethernet- a type of cable used to connect devices in a wired network
what are the pros of a point to point topology?
Minimal latency as data travels directly between the connected devices
It offers a dedicated and direct channel for communications between the connected devices
It's simple to set up and wires only a direct link between the two devices
what is a protocol?
Protocol- a set of rules or standards that allow devices to communicate with each other over a network in computer networking protocol define how data is formatted, transmitted , and received so that different devices can understand and exchange information.
How has computer networking changed the way the world communicates and shares information?
Computer networking has transformed global communication and information sharing from delayed, physical processes into instant, borderless digital exchanges
what is a bus topology?
Bus topology is a network setup where all devices connect to a single central cable, called the backbone or "bus," through which data travels to reach its destination
