History of Programming
A programming language is a way that humans
can communicate with computers. There are
many different types of programming
languages that are used today. Like real
languages they are constantly changing and
The first computers
The first computers
The U.S government
Von Neumann creates the fundamental concepts of
1.Programs should not be hardwired, making
the computer architecture more simple
2.Programs should be able to branch logically
instead of being linear
Grace Hopper creates first compiler
ones and zeros
First generation of programming languages
Fortran: specialized in scientific computing
Cobol: specialized for business
Lisp: specialized for artificial intelligence
C is developed by Dennis Ritchie
Fixed most of the problems of Pascal
was built to be fast and powerful at the cost of
being hard to read
Object Oriented programming is created
Object Oriented programs are organized
around “objects” - structured chunks of data -
instead of focused on actions. The design
emphasis becomes less on logic and more on
data. Can help reduce “spaghetti code”
through the use of class inheritance.
A programming language is a way that
humans can communicate with computers.
There are many different types of
programming languages that are used today.
Like real languages they are constantly
changing and evolving.
Java - The workhorse of programming languages
“C++ with all the knives, guns,
and clubs put away.”
Java is one of the most widely
used programming languages
and is used in server side
development due to its stability.
Used by industries such as
social media, financial
services, e commerce, and
Python - simple zen like programming language
“Compile, run and ship your pseudo-
Python is used for:
scientific and numeric computing
Web and Internet Development
C - The foundation for many other language
“Combines the power of assembly
language with the readability and
maintainability of assembly language.”
C is used for:
C++ - High performance programming language
“Enough rope to shoot yourself in the
C++ is used for:
Software for large scale ecommerce
Most microsoft applications
Perl - the duct tape of the internet
“If you put a million monkeys at a
million keyboards, one of them will
eventually write a Java program. The
rest of them will write Perl programs.”
JPerl is used for:
Intellectual property refers to the legal
ownership of what one thinks up. This could be
music you wrote, a movie you made or an
application that you programmed.
Software patents allow programmers to
monetize their work by ensuring that their work
will not be copied without their permission.
Not everybody thinks this is a good idea.
Copyright law already prevents copying, and
patents can be awfully broad.
Licensing and owning software
Owning software is where you have every right
to do what you want with the software or code.
Licensing is where you can only do certain
things detailed in the license agreement
Open source vs Commercial vs Freeware
Open source: can be freely used, changed, and shared by
anyone. But still comes with a license that may dictate how
you can use it, especially if you change it.
Commercial: produced for sale and is usually protected
under a license agreement. Usually closed source.
Freeware: available at no cost but may have restrictions on
redistribution or on modification, often not open source.
