The document discusses the early history and development of the Internet. It describes how in the 1970s, Vint Cerf and Bob Kahn designed the foundation of the Internet based on the ARPANET project funded by the US Department of Defense. The document also explains that no single person, government, or corporation is in charge of controlling and managing the Internet. Rather, an organization called the Internet Engineering Task Force (IETF), made up of volunteers, develops and promotes voluntary Internet standards and protocols.

3. Selama the binary number system can be used to mewakili
any nilai we wish,
in practice jaringan dari nilai yang we are able to represent
is limited by the number of bits we use.
Jadi, protocols for exchanging binary information must
specify in advance how many bits will form a single number
among other things.
Without knowing this information the receivers of a message
have no way of determining how to break up an incoming
stream of bits into individual numbers; it will just appear to
be a random string of 0s and 1s.

6. ASCII codes were originally 7 bits long and so there are 128 possible
values.
0-31 are “control characters” that are largely defunct and go unused;
they were formerly used to control various aspects of machines and
printers.
32-126 are printable characters and include the numbers 0-9, all 26
letters (both lowercase and uppercase), and many common
punctuation symbols.
127 is the symbol for delete.
Over time, 8 bits became a standard “chunk-size” for encoding
information. ASCII made the transition to this 8-bit encoding by just
adding an extra 0 to the front of the old 7-bit codes.

and promotes voluntary Internet standards and
protocols, in particular the standards that
comprise the Internet protocol suite (TCP/IP).
Internet - A group of computers and servers that
are connected to each other.

nobody and everybody is in charge of making the internet
work but the reason it all works together because everyone
uses the same protocols.
who develops these protocols? Who makes the final decisions?
Who is in charge? The amazing thing is that no single person,
government, or corporation is in charge.
Rather, it is a collection of citizens and volunteers interested in
defining the standards who formed a volunteer organization
called the Internet Engineering Task Force to develop and
promote voluntary internet standards IETF.

13. Many network systems, such as local ethernet and
WiFi, rely on addressing schemes
to make sure bits are received by the correct
computer based on address and
for other computers to simply ignore messages
not intended for them.

14. Packets - Small chunks of information that have
been carefully formed from larger chunks of
information.
TCP - Transmission Control Protocol - provides
reliable, ordered, and error-checked delivery of a
stream of packets on the internet. TCP is tightly
linked with IP and usually seen as TCP/IP in
writing.
