The Internet
Launched in 1969, the ARPANET works by having and Messaging Interface computers. (Nowadays,
these are our servers.)
o
The protocol between the interfaces is the Transmission Communication Protocols
/Internet(working) Protocol
o
ARPA created The Internet to help researchers communicate with each other.

TCP/IP protocol stack is a specific version of the OSI model.

Bits –Frames –Packet- Segments- Data –Data -data

OSI Model
Suppose Alice wish to send Bob a message through a message software.
This UIS (message software) is the Application, which performs functions on the data (message) and
responds to user requests.
The request is translated into network process and encrypted at Presentation
Then the computer . This is done by establishing an Inter-Host communication Session.
Data Encapsulation
Physical –Signals,
Data Link -
Network –Data segment is made into data packets, Path determination
Transport –Port Numbers, Data Segmentation, What request?
Session –Inter-Host Communication (Secure connections)
Presentation- De/Encryption, Format
Application - Functions upon Data, Request

TCP/IP Layer
User –Linking Layer –Router –Internet Layer –Internet Server A –Transport Layer –Internet Server B –
Application Layer –Host of Website
Transport Layer –
TCP: Works with Packet, send when destination is ready
UDP: Work with datagrams, Send regardless if destinations ready.
Adds port numbers
0-1023 are reserved for services
e.g. 443 is for HTTPS
Network Access Layer
Required to sent data from to receiver
Uses IP addresses
Involve selection a path and routing data through the path selected over a network

Document Summary
Ubiquitous computing across all internet of things and devices (responsive design) Meta data: a short description of a website in the head. Arpa created the internet to help researchers communicate with each other. o o. Launched in 1969, the arpanet works by having and messaging interface computers. (nowadays, these are our servers. ) The protocol between the interfaces is the transmission communication protocols. Tcp/ip protocol stack is a specific version of the osi model. Bits frames packet- segments- data data -data. Physical - data link network transport session presentation - application. Suppose alice wish to send bob a message through a message software. This uis (message software) is the application, which performs functions on the data (message) and responds to user requests. The request is translated into network process and encrypted at presentation. This is done by establishing an inter-host communication session. Network data segment is made into data packets, path determination.
