CHAPTER ONE
INTRODUCTION
Computer began long before
the modern discipline of computer science that emerged in the 20th
century and hinted at in the centuries prior the progression from mechanical
inventions and mathematical theories towards the modern concepts and machines
formed a major academic field and the basis of a massive worldwide industry.
1.1 HISTORY OF PROGRAMMING
LANGUAGE
The first programming
languages predate the modern computer. At first, the languages were code
The Jacquard Loom, invented
in 1801, used holes in punched cards to represent sewing loom arm movements in
order to generate decorative patterns automatically.
During a nine month period in 1842,
Ada Lovelace translated the memoir of Italian mathematician Luigi Menabrea
about Charles Babage’s newest proposed machine, the Analytical Engine. With the
article, she appended a set of notes which specified in complete detail a
method for calculating Bernoulli numbers with the Engine, recognized by some
historians as the world’s first computer program.
Herman Hollerith realized that he
could encode information on punch cards when he observed that rain conductors
encode the appearance of the ticket holders on the train tickets using the
position of punched holes on the tickets. Hollerith then encoded the 1890
census data on punch cards.
The first computer codes were
specialized for their applications. In the first decades of the 20th
century, numerical calculations were based on decimal numbers. Eventually it
was realized that logic could be represented with numbers, not only with words.
For example, Alonzo
Church was able to
express the Lambda Calculus in a formulaic way. The Turing Machine was an
abstraction of the operation of a tape-marking machine, for example, in use at
the telephone companies. Turing machines set the basis for storage of programs
as data in the von Neumann architecture of computers by representing a machine
through a finite number. However, unlike the lambda calculus, Turing’s code
does not serve well as a basis for higher-level languages-its principal use is
in rigorous analyses of algorithmic complexity.
1.2 DEFINITIONS OF CONCEPTS
Programming Language
A programming language is a
rotation for writing programs which and specifications of a computation or algorithm;
they are those languages that can express all possible algorithms. It usually
contains abstractions for defining and manipulating data structures or
controlling the flow of execution.
HOW KEYS/SHORT KEYS
A lot key is a combination of keys on a
computer keyboard that when pressed at one time, performs a task (such as
starting an application) more quickly than by using a mouse or other input device. Hot keys are supported by many
operating system and applications. The specific task performed by a particular
hot key varies by operating system or applications.

CHAPTER THREE
EXAMPLES OF PROGRAMMING
LANGUAGES
1)
Structure Query language (S Q
L oracle)
2)
(Basic) Begins all purpose
symbolic and instruction code
3)
(V. B scrip) visual basic
script
4)
Java: Use for implementation
of different works like designing web site, grading people according to their
marks. It can also be sue in banking system were by a program can be written in
by metrics to know a customers, it is also use in producing mini calculators.
5)
ASP (Active server pages) it
is use to write web pages which is responsible to connect some one to the data
base and also know the person profile
6)
JSL (Java script languages)
it is use in implementation of some parts of web pages like the login page or
registration page were by you would give an alert if all the fields are not
completed.
7)
HTML (hyper text markup
language) it is use for designing a web site
8)
PHP it is an implementation
language use in web design to implement the registration and web page and also
the account page and even the login page for learners of web design programmes
PHP works better wis MYSQL (on application on its own).
9)
Pascal (it can implement
some work as Java, the different is the way is been written e.g. declaration of
variable and were it can be embedded.
10) C++ is a language just like Java that is use
in implementation of some words solving mathematical problems
WSH
(Windows scripting Host)
WML
(Wireless markup language)
HB
(Hyper Builder)
UML
(Unified modeling language
ICI:
Is a general purpose interpreted computer programming language. It supports
dynamic typing, flexible data types and other language constructs similar to C.
Perl:
Perl is a high level interpreted programming language that supports dynamic
programming
Python:
it is high level programming language that supports imperative, objective
oriented and functional programming paradigms.
Charity:
It is a purely functional not Turing complete language, which means that all
its programs are guaranteed to terminate.
Joy:
It is a purely functional language that is based on a composition of functions.
Small:
The name stands for small machine Algol-like language. It provides the
programmers with abilities to write an Algol-like code that can be run on small
machines.
CHAPTER FOUR
SUMMARY AND CONCLUSION
Since shortcuts are typically an
alternative means for invoking one or more commands that would otherwise be
accessible only through a menu, a pointing device, different levels of a user
interface. For simultaneous keyboard shortcuts, one usually first holds down
the modifier key (s) then quickly presses and releases the regular
(non-Modifier) key and finally releases the modifier key (s).
