Prehistory
• The first Programming languages predate the computer.
• Languages were codes
• 1890 Herman Hollerith – Census data
Early programming
When do we start?
• The Analytical Engine, an important step in the history of
computers, is a design for a mechanical general-purpose
computer first described by English mathematician Charles
Babbage in 1837. It was the successor to Babbage's difference
engine, a design for a mechanical calculator. The Analytical
Engine incorporated an arithmetical unit, control flow in the form
of conditional branching and loops, and integrated memory,
making it the first Turing-complete design for a general-purpose
computer.
• Programming supposed to be by punch cards.
Analytical Engine: Built 63 years later
ENIAC
• Designed in 1942 General-purpose Electronic computer
• Electronic Numerical Integrator and Computer (ENIAC).
• Enormous speed advantage by using digital electronics with no
moving parts.
• Called Project-PX as its code name.
• Started in 1943, completed in 1946 costing $500,000 ( $6,000,000
in 2010 dollars).
• Designed to calculate artillery firing tables for the Army.
• First project was computations for the hydrogen bomb.
• Decimal based.

EDVAC
• Electronic Discrete Variable Automatic Computer
• Binary serial computer with automatic addition, subtraction,
multiplication, programmed division and automatic checking with
an ultrasonic serial memory.
• Capacity of 1,000 44-bit words, later set to 1,024 words: 5.5KB
• 6,000 vacuum tubes, 12,000 diodes, consumed 56kW of power,
and covered 490 Sq. Ft. Weighed 17,300 pounds.
• Designed 1946 built and operational 1949.
• Magnetic tape (Wire recorder).
EDVAC
What is a Programming Language
• A programming language is an artificial language designed to
communicate instructions to a machine, particularly a computer.
Programming languages can be used to create programs that
control the behavior of a machine and/or to express algorithms
precisely.
• The earliest programming languages predate the invention of the
computer, and were used to direct the behavior of machines such
as Jacquard looms and player pianos. Thousands of different
programming languages have been created, mainly in the
computer field, with many more being created every year. Most
programming languages describe computation in an imperative
style, i.e., as a sequence of commands, although some languages,
such as those that support functional programming or logic
programming, use alternative forms of description.
