1. • foRmula TRANslation or FORTRAN was created by John Backus and is
considered to be the oldest programming language in use today
5 major types of programming languages
• Procedural programming languages. A procedural language follows a
sequence of statements or commands in order to achieve a desired
output. ...
• Functional programming languages. ...
• Object-oriented programming languages. ...
• Scripting languages. ...
• Logic programming languages.

2. What is programming language in simple words?
A programming language is a vocabulary and set of grammatical rules for
instructing a computer or computing device to perform specific tasks.
1883: The first programming language was developed in 1883 when Ada
Lovelace and Charles Babbage worked together on the Analytical Engine,
which was a primitive mechanical computer. Lovelace was able to discern
the importance of numbers, realizing that they could represent more than
just numerical values of things.

3. • Programming domain
• The term programming domain is mostly used when referring to domain-specific
programming languages. It refers to a set of programming languages or
• What are the main programming domains?
• The 7 Domains of Programming
• Design.
• Development.
• Database.
• DevOps.
• Data Science.
• Defense (Cyber Defense)
• Digital Marketing.

4. Interactive coding
• Interactive programming, also known as live coding, refers to any
computer programming language that allows the creator to make changes
to the program while it is already running. In traditional programming, the
coder first writes out the program and then saves it. He then runs the
program on the computer.
polymorphism
• Polymorphism is a feature of object-oriented programming languages that
allows a specific routine to use variables of different types at different
times. Polymorphism in programming gives a program the ability to
redefine methods for derived classes.

5. basic of networking
Computer networks -connect nodes like computers, routers, and switches
using cables, fiber optics, or wireless signals. These connections allow
devices in a network to communicate and share information and resources.
Networks follow protocols, which define how communications are sent and
received.
four types of wireless networks
wireless local area networks
wireless metropolitan area networks
wireless personal area networks
wireless wide area networks

6. Types of networking
Local Area Network-A local area network (LAN) is a collection of
devices connected together in one physical location, such as a building,
office, or home. A LAN can be small ...
MAN (Metropolitan Area -Network)- A metropolitan area
network (MAN) is a computer network that is larger than a single
building local area network (LAN) but is located in a single geographic
area that is smaller than a wide area network (WAN). Generally, it is
several LANs interconnected by dedicated backbone connections.
WAN (Wide Area Network)-, is a large network of information that is
not tied to a single location. WANs can facilitate communication, ...
PAN (personal area network)-A personal area network, or
PAN, connects devices within a user's immediate area. Learn how PAN
networks work, and contrast them with other network types.

7. datagram sockets
• A datagram socket is the sending or receiving point for a packet
delivery service. Each packet sent or received on a datagram socket is
individually addressed and routed. Multiple packets sent from one
machine to another may be routed differently, and may arrive in any
order.
