This is used to interconnect and share computer resources in an establishment such as a corporate building, house, or several buildings in a limited area.

Local Area Network

An enterprise network covering multiple buildings in a campus environment, including universities and large organizations.

Campus Area Network

This covers multiple city buildings, traffic lights, and parking meters, connecting wirelessly as a metropolitan area network

Metropolitan Area Network

A much larger network covering vast areas, such as cities, provinces, and countries. It can be a bigger network consisting of LANs and MANs.

Wide Area Network

in campuses and branches bring users and devices together, such as linking employees in a corporate building.

Access Networks

In a company link multiple servers with data and applications and make them easily accessible to users.

Networks for Data Centers

connect users to programs and services, such as hospital employees connecting to health applications.

Wide Area Networks

reference model of the International Organization for Standardization was developed in ____? as an open standard for every communication system to allow the interlinking of different types of networks.

1984

Which Statement is NOT TRUE About the ISO Reference Model.

OSI model rejects to provide a structure for networking that secures compatibility in the network hardware

It Handles signal and media

Physical layer

Assigned for the flow of data

Data link layer

Provides addressing and routing decisions

Network layer

Manages end-to-end delivery to ensure error-free packets

Transport Layer

Establishes, manages, and terminates sessions

Session layer

Manages protocol conversion and data translation

Presentation layer

Provides support for applications

Application layer

Uses cabling and connectors to initiate network connections.

Wired Network

uses radio signals to initiate network connections. It is the most common home network configuration today.

Wireless Network

It connects devices within a local area network.

LAN Ethernet cable

interconnects networking devices but risks the broadcast of data it receives to all devices connected to it.

Hub

initiates a direct connection from the sender to the destination bypassing the data traffic to ensure data privacy, unlike a hub.

Switch

uses a cable connection to create a broadband network connection from a home network to the internet service provider (ISP)

Cable modem

provide resources, data, services, and programs to other computers or clients over a network.

Servers

A security device that monitors and secures incoming and outgoing network traffic based on established security policies.

Firewall

connects wireless devices and provides a connection to wired LANs.

Wireless access point

It is the most common way to connect wireless LANs to the ISP’s access device.

Wireless Router

combines the functionality of a modem and a router, thus making it a convenient source for Internet connectivity.

Wi-fi Modem

It is the physical and logical arrangement of nodes such as a switch or hub and connections in a network.

Network Topology

the simplest network topology where two devices, like a computer or router, are connected directly.

Point-to-point

Its deterministic nature ensures access to message transmissions at regular or fixed time intervals for each connected station. A disadvantage is that if an error changes the token pattern, it might stop circulating, causing data traffic to stop.

Token Ring

if a computer prints a file, the data communication is only between the computer and the printer. each connected device can see the computer’s data traffic to the printer.

Bus

the hub or switch supplies the network connection if a computer needs to send data to the laser printer. If a hub is used, the data is sent to the hub, which forwards it to the printer. But a hub is a multiport repeater that broadcasts and displays the data it receives to the devices connected. It also applies to all networking devices interconnected in a star network. But a hub is a multiport repeater that broadcasts and displays the data it receives to the devices connected. It also applies to all networking devices interconnected

Star

it is when the networking devices are directly connected where several paths exist between the end devices.

Mesh

Mesh topology can be divided into two types based on paths; _______ & ________

Fully meshed and Partially Meshed
