Vocabulary
A group of computers or devices connected together to share information and resources
What is Network?
A wireless technology that allows devices to connect to a network without cables
What is Wi-Fi?
A network that connects devices in a small area like schools or home
This topology has these pros and cons.
Pros:
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
Cons:
If the cable fails the entire network gets disturbed
The bus\cable length is restricted limiting the number of devices
Increased devices lead to performance issues and data collisions
What is Bus Topology?
A device like a computer or phone that requests services or resources from a server on a network
A computer or system that provides services or resources to other computers in the network, like storing files or building websites
What is a Server?
A network that connects devices in a small area like schools or home
What is a LAN?
A network that connects devices over large distances, like between cities or countries
What is a WAN?
Pros:
- The data has multiple paths. The network remains operational even if there is a failure in the area.
-mesh is an easy scalable topology. Scalability increases the network path and as a result the performance of the network.
Cons:
- it is a complicated network structure.
- it is an expensive network topology because it has multiple connections
-the installation and maintenance are challenging.
This topology has these pros and cons.
What is Mesh Topology?
A type of cable used to connect devices to a wired network
What is Ethernet?
A device that sends data between different networks and directs it to the correct destination
What is a router?
A system that translates websites, website names (like google.com) into ip addresses so you can visit websites easily.
What is a DNS?
The address of a webpage or file on the internet like a websites name
What is a(n) URL?
Cons:
-everything on a star topology depends on the central hub
-if centralized system fails the entire network is affected
-it needs more cables than other topologies
Pros:
-its easy to set up
-its the best network topology for small and medium networks
-spotting and fixing issues in a star topology is straightforward making trouble shooting a breeze
What is Star Topology?
A global network of smaller networks that connects millions of computers and devices worldwide
What is Internet?
A security tool that helps protect a network by blocking unauthorized access
What is a firewall?
Unique number assigned to each device in a network like a home address for a computer
A company that provides internet access to homes and businesses
What is a(n) ISP?
Pros:
Minimal latency as data travels directly between the connected devices
It offers a dedicated and direct channel for communication between the connected devices
It is simple to set up and wires only a direct link between two devices
Cons:
Expanding the network in this topology is challenging
Each point link requires a dedicated connection between devices
P2P topology heavily relies on the physical infrastructure. Disruptions such as a cable cut or loss of connectivity affects the whole network
A small piece of data that is sent across a network; multiple packets makeup larger data like a message or video
What is Packet?
The amount of data that can be sent over a network at one time. Similar to how wide a road is for cars
A command used to test if a device is connected to a network and how long it takes data to travel between devices
What is a Ping?
A system that translates websites, website names (like google.com) into ip addresse
What is a DNS?
Pros:
It is easily scalable by adding branches and levels
Failure in one branch doesn’t affect the network
Every segment can operate independently in a tree topology it improves the performance and security of the network
Cons:
If the central root node gets disrupted the whole network gets affected
The cost of the central hub and cables is much higher
Die to the higher archery structure troubleshooting and maintenance becomes challenging
What is a Tree Topology?
A set of rules or standards that allow devices to communicate with each other over a network. In computer networking, protocols define how data is formatted, transmitted, and received so that different devices can understand and exchange information
What is Protocol?
