Networking allows computing devices to communicate and share resources over physical or wireless connections. Key aspects of networking include computer networks, nodes, data transfer rates, client/server models, file and web servers, local area networks (LANs), wide area networks (WANs), metropolitan area networks (MANs), Internet backbone providers, Internet service providers (ISPs), protocols like TCP/IP, ports, firewalls, IP addresses, hostnames, domain names, and the domain name system (DNS) for translating names to addresses. No single entity owns the Internet as it is comprised of interconnected smaller networks.

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.
"Impact of front-end architecture on development cost", Viktor TurskyiFwdays
I have heard many times that architecture is not important for the front-end. Also, many times I have seen how developers implement features on the front-end just following the standard rules for a framework and think that this is enough to successfully launch the project, and then the project fails. How to prevent this and what approach to choose? I have launched dozens of complex projects and during the talk we will analyze which approaches have worked for me and which have not.

2. What Is Networking?
• Computer network A collection of
computing devices that are connected in
various ways in order to communicate and
share resources
Usually, the connections between
computers in a network are made using
physical wires or cables
However, some connections are wireless,
using radio waves or infrared signals
3. Networking
• The generic term node or host refers to
any device on a network
• Data transfer rate The speed with which
data is moved from one place on a
network to another
• Data transfer rate is a key issue in
computer networks
4. Networking
• Computer networks have opened up an
entire frontier in the world of computing
called the client/server model
Figure 15.1 Client/Server interaction
5. Networking
• File server A computer that stores and
manages files for multiple users on a
network
• Web server A computer dedicated to
responding to requests (from the browser
client) for web pages
6. Types of Networks
• Local-area network (LAN) A network
that connects a relatively small number of
machines in a relatively close
geographical area
7. Types of Networks
• Wide-area network (WAN) A network that
connects two or more local-area networks over a
potentially large geographic distance
Often one particular node on a LAN is set up to serve
as a gateway to handle all communication going
between that LAN and other networks
Communication between networks is called
internetworking
The Internet, as we know it today, is essentially the
ultimate wide-area network, spanning the entire globe
8. Types of Networks
• Metropolitan-area network (MAN) The
communication infrastructures that have
been developed in and around large cities
9. So, who owns the Internet?
Well, nobody does. No single person or
company owns the Internet or even
controls it entirely. As a wide-area
network, it is made up of many smaller
networks. These smaller networks are
often owned and managed by a person or
organization. The Internet, then, is really
defined by how connections can be made
between these networks.
10. Types of Networks
Figure 15.1 Local-area networks connected across a distance to
create a wide-area network
11. Internet Connections
• Internet backbone A set of high-speed
networks that carry Internet traffic
These networks are provided by
companies such as AT&T, GTE, and IBM
• Internet service provider (ISP) A
company that provides other companies or
individuals with access to the Internet
12. Internet Connections
• There are various technologies available that you can
use to connect a home computer to the Internet
– A phone modem converts computer data into an analog
audio signal for transfer over a telephone line, and then a
modem at the destination converts it back again into data
– A digital subscriber line (DSL) uses regular copper phone
lines to transfer digital data to and from the phone company’s
central office
13. Internet Connections
• Broadband A connection in which transfer
speeds are faster than 128 bits per second
– DSL connections and cable modems are broadband
connections
– The speed for downloads (getting data from the
Internet to your home computer) may not be the same
as uploads (sending data from your home computer
to the Internet)
14. Packet Switching
• To improve the efficiency of transferring information over
a shared communication line, messages are divided into
fixed-sized, numbered packets
• Network devices called routers are used to direct
packets between networks
Figure 15.4
Messages
sent by
packet
switching
15. Network Protocols
• Network protocols are layered such that
each one relies on the protocols that
underlie it
• Sometimes referred to as a protocol
stack
Figure 15.6 Layering of key network protocols
16. TCP/IP
• TCP stands for Transmission Control Protocol
TCP software breaks messages into packets,
hands them off to the IP software for delivery,
and then orders and reassembles the packets
at their destination
• IP stands for Internet Protocol
IP software deals with the routing of packets
through the maze of interconnected networks
to their final destination
17. TCP/IP (cont.)
• UDP stands for User Datagram Protocol
– It is an alternative to TCP
– The main difference is that TCP is highly
reliable, at the cost of decreased
performance, while UDP is less reliable, but
generally faster
18. High-Level Protocols
• Other protocols build on the foundation
established by the TCP/IP protocol suite
– Simple Mail Transfer Protocol (SMTP)
– File Transfer Protocol (FTP)
– Telnet
– Hyper Text Transfer Protocol (http)
19. MIME Types
• Related to the idea of network protocols
and standardization is the concept of a
file’s MIME type
– MIME stands for Multipurpose Internet Mail
Extension
– Based on a document’s MIME type, an
application program can decide how to deal
with the data it is given
21. Firewalls
• Firewall A machine and its software that
serve as a special gateway to a network,
protecting it from inappropriate access
– Filters the network traffic that comes in,
checking the validity of the messages as
much as possible and perhaps denying some
messages altogether
– Enforces an organization’s access control
policy
23. Network Addresses
• Hostname A unique identification that
specifies a particular computer on the
Internet
For example
matisse.csc.villanova.edu
condor.develocorp.com
24. Network Addresses
• Network software translates a hostname
into its corresponding IP address
For example
205.39.145.18
25. Network Addresses
• An IP address can be split into
– network address, which specifies a specific network
– host number, which specifies a particular machine in
that network
Figure 15.9
An IP address is
stored in four
bytes
26. Domain Name System
• A hostname consists of the computer name
followed by the domain name
• www.dpssrinagar.com is the domain name
– A domain name is separated into two or more
sections that specify the organization, and possibly a
subset of an organization, of which the computer is a
part
– Two organizations can have a computer named the
same thing because the domain name makes it clear
which one is being referred to
27. Domain Name System
• The domain name system (DNS) is
chiefly used to translate hostnames into
numeric IP addresses
– DNS is an example of a distributed database
– If that server can resolve the hostname, it
does so
– If not, that server asks another domain name
