Computer Science - Classification of Programming Languages
Programming Languages are broken down into High level and Low level languages. This slideshow shows how they are classified and explains low level and high level languages in depth.
Programming Languages Categories / Programming Paradigm By: Prof. Lili Saghafi Professor Lili Saghafi
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.
Low level, High level and Middle level programming languages

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

3. Programming Language
• A programming Language is a notational system
intended primarily to facilitate human-machine
interaction.
• The notational is understood both by human and
machine.
• The programming language has Syntax, and
language elements have Semantics.
CSC141 Introduction to Computer Programming
4. What is a program?
• A program is something that is produced using a
programming Language.
• A program is a structured entity with
Semantics.
CSC141 Introduction to Computer Programming
6. What is programming?
• Programming is a Science:
Because it implement the algorithms describe by
mathematics and science.
• Programming is a Skill:
Because it requires design efforts.
• Programming is an Engineering:
Because it requires a tradeoffs between program
size, speed, time (required for development and
debugging) and maintainability among many
solutions.
• Programming is an Art
It requires creativity and employ imagination.

8. Levels/Generations of Programming Languages
• 1st Generation Programming language (1GL)
• Machine Language: 0s or 1s
• 2nd Generation Programming language (2GL)
• Assembly Language : Mnemonics
• 3rd Generation Programming language (3GL)
• High-Level Languages ; (procedure oriented or
Object Oriented)
• 4th Generation Programming language (4GL)
• Very-High-Level Languages
• 5th Generation Programming Language
• Natural Languages
CSC141IntroductiontoComputerProgramming
CSC141 Introduction to Computer Programming
9. Machine language (1GL)
• The lowest level of language.
• The language used to program the first-
generation 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.
CSC141 Introduction to Computer Programming
10. 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
CSC141 Introduction to Computer Programming
11. 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.
CSC141 Introduction to Computer Programming
12. 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++
CSC141 Introduction to Computer Programming
13. 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)
CSC141 Introduction to Computer Programming
14. Natural Languages (5GL)
• Two types
• Ordinary Human Languages; like English.
• Programming language that use human
language to give people a more natural
connection with computers.
• 5GLs are designed to make the computer solve
a given problem without the programmer.
• Natural languages are part of the field of study
known as Artificial Intelligence.
• Develop machines to emulate human-like
qualities such as learning, reasoning,
communicating, seeing and hearing.
CSC141 Introduction to Computer Programming
16. Programming Paradigms
A number of programming paradigms are:
• Procedural/Imperative Programming
• Functional Programming
• Declarative Programming
• Object Oriented Programming
• Event driven Programming
• Parallel Programming
CSC141 Introduction to Computer Programming
17. 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;
CSC141 Introduction to Computer Programming
18. Procedural or Imperative: … Contd
Example of imperative languages are:
• Assembly language
• COBOL
• Pascal
• C and C++
CSC141 Introduction to Computer Programming
19. 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.
CSC141 Introduction to Computer Programming
20. 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
CSC141 Introduction to Computer Programming
21. History of C Language
• A general-purpose computer programming language.
• Developed between 1969 and 1973 by Dennis Ritchie at
the Bell Telephone Laboratories for use with the UNIX
operating system.
• Descendant of Ken Thompson’s language “B”
• The first C programming language standard was
published in 1978 as “The C Programming Language” by
Kernighan and Ritchie (K&R).
• "ANSI C" was the second C programming language
standard published in 1989.
• ISO approved “ANSI C” in 1990.
• The latest stable release is C11.
