Sound – vibration – voltage – vibration - sound

3. World Wide Communication
Voltage amplitude (signal strength) is lost over distance (100+ miles).
Voltage is easily amplified after certain distances preserving content.

typical baud (30-120/char/sec)
56K baud maximum
dial-up
1 twisted pair
$15 a month plus time and distance
Digital Communication
256K baud using 2 twisted pair
“dial-up”
$100 a month plus time and distance

9. Digital Subscriber Line (DSL)
Identical methodology for copper twisted pair (balanced line)
or coaxial cable (unbalanced line)
Very High Frequency (VHF) carrier is impressed with data using frequency shift keying (FSK)
Theoretical maximum speed of 5M baud
Signal creates an EM field about
the “twist”.
Signal amplitude (strength) is
tuned limiting distance
subscriber is to the telco switch.
Only subscriber data on line.
More secure.
Signal creates an EM field about the
ground braid.
Signal amplitude can be as high as
tolerable crosstalk.
Possible multiple channels.
All subscribers‘ data downwind of
ISP’s switch/router appears at all
subscribers‘ MODEMs.

10. Anonymity Personally Identifiable Data Collection Security Surveillance
In 2017, the trump administration removed all privacy safeguard regulations from the Internet separate from the public domain.
Your ISP is now enabled to legally surveil you and collect any information passing through their circuits and disperse that data to whomever they please.
Marketing companies like AdChoice read other companies’ cookies on your computer, without consulting the “Terms and Agreements”, to determine the advertising they will deliver to you.
To what level a user wishes to achieve anonymity, prevent personally identifiable data collection, secure all data, and defeat intrusive surveillance, will involve additional software, an investment of time and effort, third party services, and significantly more processor power.

11. What Is A Proxy Server ? you are here… or here… or here …
At its simplest, a proxy server makes you appear somewhere else:
you are here…
or here…
or here …
The proxy places the user beyond the reach of an ISP’s DNS surveillance.
Prior to W7 the NIC could only forward network data to the default gateway or a proxy server using an IP address. W7 and forward has a built-in VPN client and the ability to manage multiple VPN connections. Adding VPN reduces the success of user data surveillance.

12. What Is A VPN ?
Virtual Private Network. A point-to-point communication method providing the maximum privacy and security possible over an otherwise public network. There is a lot going on in a VPN:
Authentication of the participants.
Administration of at least 3 levels of TCP/IP
Utilization of security certificates
Encryption/Decryption of TCP/IP headers/trailers, URL destination,
origination IP, and data.
Operation of the VPN involves trade-offs in:
overall security
communication speed
consumption of processor power
ability to forestall failover
Often the VPN server side provides the VPN client with Internet Proxy services.

13. A Multitude Of Tunneling Protocols
IKEv2
Internet Key Exchange – developed by MS and Cisco using IPsec
IPsec is a framework of methodologies concerning cryptology
OpenVPN
Open Source – utilizes SSL/TLS for key exchange
SoftEther
Open-source, cross-platform, multi-protocol developed as part of Daiyuu Nobori's
master's thesis research at the University of Tsukuba.
L2TP/IPsec
Layer 2 Tunneling Protocol – low level. Uses IPsec for Anonymity
SSTP
Secure Socket Tunneling Protocol (SSTP) transports PPP traffic using SSL/TLS with key
negotiation, encryption and traffic integrity checking.
PPTP
Point-to-Point Tunneling Protocol is an obsolete method with many known security
issues.

14. Setting Up A 3rd Party VPN
I chose Hide.me VPN. It is free to try; did not require a credit card.
It could be installed without downloading anything.
Click register. Enter a user ID and password. Provide an address. Click the verify button in the . Done.
