COMPUTER NETWORK
TOPOLOGIES
STAR TOPOLOGY
Each node has a dedicated set of wires connecting it to a central network hub. Since all traffic passesthrough the switch (formally known as a hub), the switch becomes a central point for isolating network problems and gathering network statistics.
RING TOPOLOGY
All messages/data packets travel through a ring in the same direction (either "clockwise" or "counterclockwise") from one network device to the next and features a closed loop.
BUS TOPOLOGY
Each node attaches directly to a common single cable. The backbone functions as a shared communication medium that devices attach or tap into with an interface connector.
MESH TOPOLOGY
all the network nodes are individually connected to most of the other nodes. There is not a concept of a central switch, hub or computer which acts as a central point of communication to pass on the messages.
HYBRID TOPOLOGY
Hybrid refers to integrating two or more different Hybrid topologies. Star-Ring and Star-Bus networks are most common examples of hybrid network. While this topology has positives such as reliability and effectiveness, it is costly and complex in design and infrastructure..
COMPONENTS
INTERFACES
Every device on the network has network interface of some kind. Referred to as a NIC (network interface card), NIC (network interface card), NIC (network interface card), it is generally integrated into a computer's motherboard. It can also come as a separate card.
HUBS/SWITCHES
When you connect multiple workstations on a network, they plug into a central device known as a "Hub". The hub has the job of moving the network signal from one cable to another.
ROUTERS
A router has a lot more capabilities than hubs/ switches, as they can analyze the data being sent over a network and send it to another network or over a different network. In home networks, routers are commonly used to share an Internet connection between multiple computers.
TYPE
INTERNET
It is a worldwide/global system of interconnected computer networks. It uses the standard Internet Protocol (TCP/IP).
INTRANET
Implementation of Internet technologies within an organization rather than for external connection to the global internet.
DESIGNS
CLIENT/SERVER
In this Network Design, one node acts as a server that provides the services, and the other nodes (clients) request services from the server. Generally, a server is a powerful device with good processing power and storage capacity.
PEER TO PEER (P2P)
This network is a good choice for needs of small businesses where the users are situated in the same area and the business does not think it will grow.
DEFINITION
a set of two or more computers a set of two or more computers connected to each other
BENEFITS
Is a core tool for communication, collaboration, knowledge management, and culture and engagement with more flexibility, capabilities, and user-friendly features which has the ability to save critical time, money, and resources.
