number 15 onwards
1. Examples of "fun" inter-
amazon echo, internet refridgerator, IP
net-connected devices
pic- ture frame, pacemaker and
monitor, VR, se- curity camera,
internet phones, sensorized bed
matress, fitbit
2. What is the internet? billions of connected computing
devices
3. hosts end systems
4. running network at apps
Internet's "edge"
5. packet switches -forward packets, chunks of data (ex:
routers, switches)
6. communication links fiber, copper, radio, satellite
(transmission
rate = bandwidth)
7. networks collection of devices, routers, links:
managed by an organization
8. Internet "network of networks" and
interconnected ISPs(Internet Service
Provider)
9. protocols control sending and receiving
messages (ex: HTTP(Web), streaming
video, SKype, TCP, IP, WiFi, 5G,
Ethernet

13. The Internet as a "service" web, streaming, video, multimedia,
view is infrastructure that telecon- frencing, email, games, e-
commerce, social media,
interconnected appliances, etc
, CSCI 4500: Chapter 1 Summaries later Questions start from

provides services to
applica- tions, such as:
14. The Internet as a "service programming interface to distributed
view provides.... appli- cations ("hooks" allowing
sending/receiving apps to "connect", to
use Internet transport service. Provides
service options, analogous to postal
service)
15. What are human protocols? - what's the time?
- I have a question?
- introductions
ie, specific messages sent and specific
ac- tions taken when message received
or other ovenets
16. What are network protocols? computers(devices) rather than
humans, all
communication activity in Internet
governed by protocols
17. What are protocols? define the format and order of
messages sent
and received among network
entities, and actions taken on msg
, CSCI 4500: Chapter 1 Summaries later Questions start from

transmission, receipt
18. What is the network hosts: clients and servers
edge? (Internet Structure) servers often in data centers
