Machine language uses binary to directly instruct the computer but is tedious for programmers. Assembly language replaces machine code with mnemonics like ADD and SUB making it easier. High-level languages are the easiest for programmers being English-like but require compilation to machine code, making them slower than low-level languages.
Programming languages are systems of communication used to develop both system and application software by giving computers sets of instructions. There are five main types of programming languages: high-level languages, machine languages, assembly languages, fourth generation languages (4GL), and natural languages. High-level languages are problem-oriented and resemble English, making them easier to use than machine languages but requiring translation. Machine languages use binary and do not require translation but are difficult for humans. Assembly languages use mnemonics for instructions, requiring less translation time than machine languages. 4GLs are used for database and management systems, while natural languages allow users to give instructions to computers in languages like English.
A programming language is a set of rules that allows humans to tell computers what operations to perform. Programming languages provide tools for developing executable models for problem domains and exist at various levels from high-level languages that are closer to human language to low-level machine code. Some of the principal programming paradigms include imperative, object-oriented, logic/declarative, and functional programming. Popular high-level languages include FORTRAN, COBOL, BASIC, C, C++, Java, and markup languages like HTML and XML.
There are two types of programming languages: high-level languages and low-level languages. High-level languages are closer to human languages and provide more abstraction from machine-level instructions, while low-level languages like assembly language closely map to processor instructions. Programs written in high-level languages need to be translated into machine code using compilers or interpreters, while low-level language programs are assembled directly into machine code. Common examples of high-level languages include C++, Java, and Python, while assembly language and Basic are examples of low-level languages.
This document discusses the evolution of programming languages from early machine languages to modern higher-level languages. It begins with an introduction to human and computer languages. It then covers the development of machine languages, assembly languages, and higher-level languages like FORTRAN and COBOL. The document discusses the advantages of each generation of languages and examples of languages from the 1950s to modern times.
This document discusses different types of programming languages:
- Low-level languages like assembly are close to machine instructions and require knowledge of computer hardware. High-level languages abstract programming concepts and are easier for humans.
- Third-generation languages like FORTRAN and COBOL are machine-independent but still textual. Fourth-generation languages allow visual programming.
- Fifth-generation languages are designed for artificial intelligence and problem-solving.
There are three main categories of programming languages: machine languages, assembly languages, and higher-level languages. Higher-level languages are divided into five generations - third being the first true English-like languages, fourth allowing visual programming, and fifth hypothetically using artificial intelligence. The software development life cycle has five phases - needs analysis, program design, development, implementation, and maintenance.

Lect 1. introduction to programming languagesVarun Garg
A programming language is a set of rules that allows humans to communicate instructions to computers. There are many programming languages because they have evolved over time as better ways to design them have been developed. Programming languages can be categorized based on their generation or programming paradigm such as imperative, object-oriented, logic-based, and functional. Characteristics like writability, readability, reliability and maintainability are important qualities for programming languages.
This document discusses different programming paradigms and languages. It describes batch programs which run without user interaction and event-driven programs which respond to user events. It lists many popular programming languages from Machine Language to Java and C#, and describes low-level languages that are close to machine code and high-level languages that are more human-readable. It also discusses the different types of language translators like compilers, interpreters, and assemblers and how they convert code between languages. Finally, it covers testing, debugging, and different types of errors in programming.
The document discusses computer languages and divides them into two types: high-level languages (HLL) and low-level languages (LLL). HLL are closer to human language but require compilation, while LLL are more machine-specific but faster. Both have advantages and disadvantages - HLL are easier for humans but slower, while LLL are faster but more difficult for humans. The document concludes that modern computers now use more user-friendly languages than older low-level ones.
Popular third generation languages include C++, Visual Basic, and Java. C++ is widely used for hardware design. Visual Basic is relatively easy to learn with an
A programming language allows people to create programs that instruct machines what to do. There are different levels of programming languages from high-level to low-level. High-level languages like C, C++, Java, HTML and XML are more understandable for programmers as they are further abstracted from hardware. Low-level languages work more closely with hardware and do not require compilation. The document then provides examples of programs in C, Java, HTML and CSS to illustrate these points.
The document provides an introduction to programming languages. It discusses the different levels of programming languages including low-level languages like machine language and assembly language that are close to hardware, and high-level languages like C++, Java, and Python that are more abstract. It also covers procedural languages which specify steps to complete tasks and object-oriented languages which model real-world objects. Examples are given of popular languages from each paradigm like C, Pascal, and PHP for procedural and C++, Java, Ruby for object-oriented.
There are four categories of computer languages: high-level languages, low-level languages, assembly language, and machine language. High-level languages are closer to human language and need translators to be understood by computers. Low-level languages are closer to machine language and do not need translators. Assembly language sits between high-level and machine language by using mnemonic codes. Machine language consists of binary and is the only language computers can directly understand. Translators like compilers, interpreters, and assemblers are used to convert between these language categories.
The document discusses the history and evolution of programming languages from the first to fifth generations. It notes that Charles Babbage proposed the first general-purpose computer called the Analytical Engine in 1837 and that Ada Lovelace was the first computer programmer. Programming languages have evolved from machine code consisting of 1s and 0s, to assembly languages using symbolic codes, to modern high-level languages that are closer to human languages like C++, Java, Python and SQL. Fifth generation languages allow solving problems by defining constraints rather than writing algorithms.

Computer programming is the process of writing source code instructions in a programming language to instruct a computer to perform tasks. Source code is written text using a human-readable programming language like C++, Java, or Python. A program is a sequence of instructions that performs a specific task. Programmers write computer programs by designing source code using programming languages. Programming languages are classified as high-level or low-level. High-level languages provide abstraction from computer details while low-level languages require knowledge of computer design. Language translators like compilers and interpreters convert source code into executable programs.
There are four generations of programming languages:
1) First generation languages are machine code/binary, the only language computers can understand directly.
2) Second generation languages are assembly languages which provide mnemonics to represent machine code instructions.

A programming language is a notation designed to connect instructions to a machine or a computer.
Programming languages are mainly used to control the performance of a machine or to express algorithms.
At present, thousands of programming languages have been implemented.
In the computer field, many languages need to be stated in an imperative form, while other programming languages utilize declarative form.
The program can be divided into two forms such as syntax and semantics.
The document discusses programming languages and their importance. It covers the following key points:
- A programming language allows computation to be described in both machine-readable and human-readable form. Most languages today are high-level languages.
- Studying programming languages improves one's ability to choose the right language for a task, learn new languages, and better understand how language features are implemented.
- Major programming domains include scientific, business, artificial intelligence, systems, and web applications. Each domain utilizes languages suited to its particular needs and purposes.
This document discusses different programming domains including scientific applications, business applications, artificial intelligence, systems programming, and web software. It provides details on each domain, such as scientific applications using floating point computations and Fortran being the first language. Business applications used special computers and languages like COBOL. Artificial intelligence uses symbolic rather than numeric computations and LISP was the first widely used AI language. Systems programming requires efficient languages like C and C++. Web software uses an eclectic collection of languages and dynamic content is provided by embedding code in HTML documents.
This document discusses programming languages. It begins by asking what a programming language is and why there are so many types. It then defines a programming language as a set of rules that tells a computer what operations to perform. The document discusses the different types of programming languages like low-level languages close to machine code and high-level languages closer to English. It covers many popular programming languages from early generations like FORTRAN and COBOL to modern languages like C, C++, Java, and scripting languages. It concludes by discussing qualities of good programming languages like writability, readability, reliability and maintainability.
This document provides an introduction to programming concepts such as algorithms, pseudocode, and flowcharts. It defines computer programming as the process of writing code to instruct a computer, and explains that programming languages allow users to communicate instructions to computers. The document outlines different types of computer languages including low-level languages like machine language and assembly language, and high-level languages like procedural, functional, and object-oriented languages. It also discusses specialized languages, translator programs, and program logic design tools for solving problems algorithmically through pseudocode and flowcharts.
This document provides an introduction to programming languages and Python. It discusses what a program is, different categories of software, and types of programming languages including machine language, assembly language, and high-level languages. It also covers programming paradigms like imperative, logical, functional, and object-oriented. The document outlines the software development life cycle and describes key areas where Python is commonly used like academia, scientific tools, machine learning, and web development.

Artificial Intelligence (AI) has revolutionized the creation of images and videos, enabling the generation of highly realistic and imaginative visual content. Utilizing advanced techniques like Generative Adversarial Networks (GANs) and neural style transfer, AI can transform simple sketches into detailed artwork or blend various styles into unique visual masterpieces. GANs, in particular, function by pitting two neural networks against each other, resulting in the production of remarkably lifelike images. AI's ability to analyze and learn from vast datasets allows it to create visuals that not only mimic human creativity but also push the boundaries of artistic expression, making it a powerful tool in digital media and entertainment industries.
Decolonizing Universal Design for LearningFrederic Fovet
UDL has gained in popularity over the last decade both in the K-12 and the post-secondary sectors. The usefulness of UDL to create inclusive learning experiences for the full array of diverse learners has been well documented in the literature, and there is now increasing scholarship examining the process of integrating UDL strategically across organisations. One concern, however, remains under-reported and under-researched. Much of the scholarship on UDL ironically remains while and Eurocentric. Even if UDL, as a discourse, considers the decolonization of the curriculum, it is abundantly clear that the research and advocacy related to UDL originates almost exclusively from the Global North and from a Euro-Caucasian authorship. It is argued that it is high time for the way UDL has been monopolized by Global North scholars and practitioners to be challenged. Voices discussing and framing UDL, from the Global South and Indigenous communities, must be amplified and showcased in order to rectify this glaring imbalance and contradiction.
This session represents an opportunity for the author to reflect on a volume he has just finished editing entitled Decolonizing UDL and to highlight and share insights into the key innovations, promising practices, and calls for change, originating from the Global South and Indigenous Communities, that have woven the canvas of this book. The session seeks to create a space for critical dialogue, for the challenging of existing power dynamics within the UDL scholarship, and for the emergence of transformative voices from underrepresented communities. The workshop will use the UDL principles scrupulously to engage participants in diverse ways (challenging single story approaches to the narrative that surrounds UDL implementation) , as well as offer multiple means of action and expression for them to gain ownership over the key themes and concerns of the session (by encouraging a broad range of interventions, contributions, and stances).

• Machine Language: 0s or 1s
8. CSC141 Introduction to Computer Programming
Machine language (1GL)
• The lowest level of language.
• The
language used to program the firstgeneration computers.
• The instructions in 1GL are made of binary
numbers, represented by 1s and 0s.
• 1s and 0s correspond to the on and off states of
electrical switches.
• Suitable for the understanding of the machine but
very much difficult to interpret and learn by the
human programmer.
9. CSC141 Introduction to Computer Programming
Assembly language (2GL)
• Low-level language that allows a programmer to
use abbreviations or easily remembered words
instead of numbers.
• These Observations are called Mnemonics. These
Mnemonic are Opcode and Operands
For Example:
ADD AX, BX
MOV CX, AX
INC CX
Op-code; ADD, MOV, INC
Operands AX, BX,CX
10. CSC141 Introduction to Computer Programming
Assembly language (2GL)
• Programmer can write instructions faster but it is
still not an easy language to learn.
• Drawback: The language is specific to a
particular processor family and environment.
(Machine Dependent Language)
• Assembler – A program that translates the
assembly language program into machine
language.
11. CSC141 Introduction to Computer Programming
High Level languages (3GL)
•A
High-Level Language is an English-like
language.
• It is a refinement of a second-generation
programming language.
• It allowed users to write in familiar notation, rather
than numbers or abbreviations.
• Most High-level languages are not Machine
Dependent.
• Translator for High-level languages is either a
Compiler or an Interpreter.
• Examples of High-level languages:
―FORTRON
―COBOL
―BASIC
―C and C++
12. CSC141 Introduction to Computer Programming
Very-High-Level Languages (4GL)
• 4GLs
are much more user-oriented and allow
programmers to develop programs with fewer commands
compared with 3GLs.
• Non-Procedural Language; Programmers don’t have to
specify all the programming logic, only tell the computer
what they want done.
• Saves a lot of time.
• 4GLs
consist
of
report
generators,
query
languages, application generators, and interactive
database management system
• For example:
• RPG III (Report Generator)
• SQL (Structured Query Language)
• NOMAD and FOCUS (DBMS)

Programming Paradigms
A number of programming paradigms are:
• Procedural/Imperative Programming
• Functional Programming
• Declarative Programming
• Object Oriented Programming
• Event driven Programming
• Parallel Programming
16. CSC141 Introduction to Computer Programming
Procedural or Imperative:
• Imperative programs emphasize “tell what to do”
• When we say “ Do this, then do this, then do
this, and if xx, do this, otherwise do this” This is
imperative programming:
• They focus on evaluating expressions and storing
results in a variable.
• The most common imperative language consists
of statements such as:
a = 10;
b = 5;
c = a + b;
17. CSC141 Introduction to Computer Programming
Procedural or Imperative: … Contd
Example of imperative languages are:
• Assembly language
• COBOL
• Pascal
• C and C++
18. CSC141 Introduction to Computer Programming
Is there any Best Programming Language?
• Programming Language is probably used most
efficient if it is well suited for a specific task.
• For example
• Business applications are often written in
COBOL.
• Beginners to programming use BASIC.
• Scientific programming is often undertaken with
either FORTON, PASCAL or C.
19. CSC141 Introduction to Computer Programming
Language Evaluation Criteria
• Readability:
measure programmer ease in reading source
code
• Orthogonality: include context sensitive restrictions.
• Applicability: this is best suited as “use the right tool for the
job”
• Writ ability:
includes simplicity and orthogonality and
support for the abstraction
• Reliability:
include type checking and inspection handling
• Cost:
includes learning and writing cost, productivity,
compilation cost, execution cost, debugging
cost etc.
• Other:
flexibility of control statements and availability
of data structures
