1 Fundamentals Flashcards
is a group or system of interconnected people or things.
NETWORK
is a group of system of interconnected computers.
COMPUTER NETWORK
refers to interconnected computing devices that can exchange data and share resources with each other.
COMPUTER NETWORKING
4 WAY OF COMPUTERS TO LINK WITH NETWORKS
- Cables
- Satellites
- Light Beams
- Radio Waves
used to connect one network device to other network devices or connect two or more computers.
Cables
transmit and receive data from a satellite dish.
Satellites
used in optical networks. Fiber Optics Cables transmit data via fast travelling pulses of light.
Light Beams
transmitter transmits radio wave on one end of the system (source) and the receiver receives the radio wave at the other end (destination)
Radio Waves
10 TYPES OF COMPUTER NETWORKS
1.Personal Area Network (PAN)
2.Local Area Network (LAN)
3.Wide Area Network (WAN)
4.Wireless LAN (WLAN)
5.Campus Area Network (CAN)
6.Metropolitan Area Network (MAN)
7.Storage Area Network (SAN)
8.Passive Optical LAN (POLAN)
9.Enterprise Private Network (EPN)
10.Virtual Private Network (VPN)
is the most basic type of computer network. 10 METER RANGE
Personal Area Network (PAN)
is the most frequently used network. It connects computer together through a common communication path.
Local Area Network (LAN)
connects computer over a large geographical distance.
Wide Area Network (WAN)
acts as a local LAN but makes use of wireless technology.
Wireless LAN (WLAN)
is bigger than LAN but smaller than WAN. Typically used in schools or colleges.
Campus Area Network (CAN)
is larger than a LAN, smaller than a WAN. Connects through a geographical distance through a shared communication path over a city.
Metropolitan Area Network (MAN)
connects groups of storage devices to several servers.
Storage Area Network (SAN)
is an alternative of LAN. Uses optical splitters.
Passive Optical LAN (POLAN)
mostly used by businesses that want a secure connection.
Enterprise Private Network (EPN)
extends a private network access the internet.
Virtual Private Network (VPN)
5 BASIC NETWORK COMPUTER COMPONENTS
- Servers
- Shared Data
- Transmission Media
- LAN Cable
- Clients
are computers that hold shared files, program, and network operating system.
Servers
are data that file servers provides to clients.
Shared Data
are facilities used to interconnect computers in networks.
Transmission Media
used to connect a device to the internet or to other devices.
LAN Cable
this are the customers.
Clients
refers to how various nodes, devices, and connection on your network are physically or logically arranges in relation to each other.
Network Topology
a type of network topology that refers to physical connections and interconnection between nodes.
Physical Network Topology
a type of network topology that is a little more abstract, refers to conceptual understanding of how and why a network is arranged.
Logical Network Topology
7 TYPES OF NETWORK TOPOLOGY
- Star Topology
- Bus Topology
- Ring Topology
- Dual Ring Topology
- Tree Topology
- Mesh Topology
- Hybrid Topology
the most common network topology. It is laid oud to every node in the network is directly connected to one central hub.
Star Topology
orients all the devices on a network along a single cable running in a single direction. Called a line or backbone topology.
Bus Topology
is where nodes are arranged in a circle. Data can travel through the ring in either direction.
Ring Topology
it is a full-duplex, data can move in both directions.
Dual Ring Topology
the central nodes function as a sort of trunk for the network with nodes extending outward in a branch-like fashion.
Tree Topology
is an intricate and elaborate structure of point-to-point connections where the nodes are interconnection.
Mesh Topology
a mesh topology where nodes are mostly interconnected.
Partial Mesh Topology
a mesh topology where nodes are fully connected.
Full Mesh Topology
combines two or more different topology structures.
Hybrid Topology
