System Software
serves as the manager of a computer system and enables the execution of other applications, typically built for general-purpose computers and microprocessors.
Embedded software
also known as firmware, is responsible for initializing and controlling specific hardware components. It also acts as a interaction layer between hardware and the higher-level software.

Artificial Intelligence
a complex and hybrid system that employs machine learning and other deep learning that aims to mimic or even outperform human intelligence and efficiency for various tasks.
Software development
refers to the entire process from the initial ideation to the maintenance of a software. It involves skills on specific programming languages, libraries, frameworks, and tools depending on the specific project requirements.
it is the “application of a systematic, disciplined, quantifiable approach to the development, operation, and maintenance of software.”
What is software engineering according to IEEE (1990)?
Sound Engineering principles
It means that we will also borrow and apply knowledge found on related fields such as Project Management which we will cover in-depth later on.
Economical Software
Businesses operate for profits, which means software contractors and vendors apply “sound engineering principles” to increase profitability while also satisfying the needs of their client.
Efficiently works on real machines
This includes security, performance, stress, and reliability testing to ensure it works as intended when subjected to extreme stress or usage.
software development with carpentry, then software engineering is the same as civil engineering. In software engineering, we build high-quality projects that satisfy clients, strongly withstand risks, and drive long-term sustainability as a software contractor or vendor.

Information Engineering methodology
It is a methodology where it is data-focused and with strong understanding in business systems and information technology. Emphasis on data and data structures
Object-oriented methodology
A methodology where it focuses on the identification of objects, classes, and its relationships through a design model. Its deliverables include conceptual and UML diagrams.
V model
It is a model that emphasizes on verification and validation, it ensures that the product meets requirements and functions correctly.
Evolutionary model
This model introduces improved or added features through modified requirements, it is similar to an iterative model but with each iteration is a complete software product.
Iterative/Incremental model
This model focuses on an initial implementation and adding a broader feature set and complexity on each iteration until the final system is completed.
Spiral model
This model is a combination of sequential and prototype models followed in a more defined manner, …, and repetition or the whole process until the client is satisfied
Waterfall model
A classic lifecycle model where software development is done sequentially. This simplicity makes it applicable to small projects conducted by those outside the computing discipline
Prototype model
This model is a trial-and-error approach between the developer and the client, it is useful when the requirements are not yet known in detail. It is an iterative rebuilding until the client expresses satisfaction
