A(n) ________ in a computer network is any device that is connected to the network and is capable of sending, receiving, or forwarding data.
4
New cards
Server
A network ______ is like a central hub that connects all the computers and devices in a network.
5
New cards
Terminal
________: Network hardware device used for entering into, or displaying data from, another computer or computing system.
6
New cards
Network Backbone
The ________: Responsible for carrying most of the network traffic at a high speed.
7
New cards
Network
An interconnected or interrelated chain, group, or system
8
New cards
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
9
New cards
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
10
New cards
Devices
Computer, Printers, Switches, Routers
11
New cards
Media
Physical connection such as copper wires or fiber optic cables; Wireless connection such as Wi-Fi or Radio/Cellular frequency
12
New cards
Network Adapter
translator between components(devices) over the media in which the data is sent
13
New cards
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
14
New cards
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
15
New cards
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
16
New cards
Redistribution Node
A(n) _____________ is a device in a computer network that helps to distribute data traffic between different networks
17
New cards
Types of Network Backbones
Serial, Hierarchical/Distributed, Collapsed, Parallel
18
New cards
Serial Network Backbone
One backbone cable, multiple switches connected
19
New cards
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.

New cards
Collapsed Network Backbone
A(n) _____________ uses a single router to connect all network segments
21
New cards
Parallel Network Backbone
Like a Collapsed Network Backbone but uses multiple cable connections
22
New cards
Client
A(n) _____ in computer networks is a device or software that requests services or resources from other nodes/servers/clients
23
New cards
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
