Module 1 Lesson 1 Basic Network Theory and Terminology

Media

Media

________: Physical connection such as copper wires or fiber optic cables; Wireless connection such as Wi- Fi or Radio /Cellular frequency.

Peer

A(n) ________ in computer networks refers to any device or computer that shares and receives data with other devices or computers on the network.

Node

A(n) ________ in a computer network is any device that is connected to the network and is capable of sending, receiving, or forwarding data.

Server

A network ______ is like a central hub that connects all the computers and devices in a network.

Terminal

________: Network hardware device used for entering into, or displaying data from, another computer or computing system.

Network Backbone

The ________: Responsible for carrying most of the network traffic at a high speed.

Network

An interconnected or interrelated chain, group, or system

Computer Network

Two or more computers that are connected with one another for the purpose of communicating data electronically and sharing resources such as files, printers, and internet connections

Components

A computer network consists of several ____________, including hardware devices such as computers, routers, switches, and servers, as well as software applications and protocols that enable communication and data transfer between these devices

Devices

Computer, Printers, Switches, Routers

Media

Physical connection such as copper wires or fiber optic cables; Wireless connection such as Wi-Fi or Radio/Cellular frequency

Network Adapter

translator between components(devices) over the media in which the data is sent

Network Operating System

it tells the network how to work together in order to perform as efficiently as possible over the adapter, over the media and with each of the devices

Node

A(n) ____ in a computer network is any device that is connected to the network and is capable of sending, receiving, or forwarding data

Endpoint Node

A(n) __________ is a device or a computer that is located at the end of a network and is used to initiate or terminate communication

Redistribution Node

A(n) _____________ is a device in a computer network that helps to distribute data traffic between different networks

Types of Network Backbones

Serial, Hierarchical/Distributed, Collapsed, Parallel

Serial Network Backbone

One backbone cable, multiple switches connected

Hierarchical/Distributed Network Backbone

This network structure looks like a tree branch with many branches stemming from one trunk. It's used to connect devices in a way that allows for efficient communication. The main trunk is responsible for routing traffic to and from the smaller branches, making it easier to manage and organize data flow.

Collapsed Network Backbone

A(n) _____________ uses a single router to connect all network segments

Parallel Network Backbone

Like a Collapsed Network Backbone but uses multiple cable connections

Client

A(n) _____ in computer networks is a device or software that requests services or resources from other nodes/servers/clients

Peer

A(n) _____ in computer networks refers to any device or computer that shares and receives data with other devices or computers on the network
