Fundamentals of computing are the foundation for computer technology. These skills include basic mathematical and programming principles, computer communications and the Internet.
Computer technology basics
Computer technology basics are important to know because computer technology is used for a variety of applications, from manufacturing to communication. The benefits of using a computer can be seen in terms of improved manufacturing accuracy, faster startup times, fewer errors in drawings and designs, and easier product design.
Computers are powerful machines that can perform complex mathematical calculations and handle a range of tasks. They also can be used for email, web browsing, and even video and audio production.
The most basic functions of a computer include processing input data and retrieving and storing information. These are accomplished by software, which is a set of instructions that tell the hardware what to do.

Computing is need for the digital era
The digital revolution – the invention of the personal computer and internet – has made the digital age possible. It has transformed nearly every aspect of modern life, from the way we communicate to the way we shop. And it has given rise to some fascinating and often contentious narratives about the technological impact of the digital revolution.
Despite the hype surrounding the digital revolution, there are many who are left behind.
There are also some sectors of the economy that are less than a fifth digitized. So, the best way to make sure you don’t get left behind is to ensure that the infrastructure that supports digitization is up to the task.
The most important nip and tuck in the digital era is the use of artificial intelligence to build smarter machines that can perform tasks such as security, safety and reliability. Unlike conventional computers, these machines can learn to perform tasks on their own without a human being standing between them. This opens up a new wave of possibilities for humans and machines.
One of the most interesting aspects of the digital revolution is that it has changed the nature of the relationships among the many different stakeholders. Rather than simply relying on a single provider, users can now connect with their loved ones, businesses, governments, and even other people.
Basic mathematical and programming principles
One of the most important skills needed to write large-scale programs is algorithmic thinking. To develop this skill, you need to understand the basics of math.
Many programming tasks require basic mathematical operations, such as addition and subtraction. You also need to be familiar with the binary number system, which is used to represent every number inside a computer.
In this course, you will learn about the structure and organization of modern digital computers. The course will introduce you to several fundamental aspects of computer systems, such as file and memory structures, and sorting algorithms.
Students will also learn to design complex computer programs and algorithms. They will learn to use application packages, such as Excel and Word, as well as to write programs in ML (math-language) and Python.
This is a high-level course that focuses on problem solving, data abstraction, algorithms, and global perspectives. It also provides an introduction to computational thinking and data communication, and prepares students for advanced placement exams.
In these courses, you will learn to design and implement efficient algorithms and data structures. Students will learn to use modern programming languages, such as Java and Python, to build and analyze complex algorithms. Some of the topics covered include sorting and searching, parallel program design, and the efficient use of memory hierarchies.
You will also learn to design circuits using propositional logic. Propositional logic is a logical theory that applies to the correctness of a program.
Analyse the resource requirements of simple algorithms and programs
The process of analysing the resource requirements of simple algorithms and programs is a vital part of computational complexity theory. This relates to how much time and space is required to perform the various steps of a particular algorithm. It is also useful when comparing algorithms. Algorithms can be broken down into modules that are analyzed to find the best solution.
While there is no single measurement that is definitive, there are several ways to estimate how much resources an algorithm requires. Some common resources include memory, speed, and the amount of data. For example, if a function requires a variable to be stored in a memory device, that’s the most obvious way to measure its resources.
In the world of computing, the most efficient algorithm is likely to use the smallest amount of resources. This is the case in many high-performance computing applications.
Another interesting measure is the worst case performance of an algorithm. This is a function of the corresponding worst case input. If you have a large amount of data to process, then you’ll be more interested in the worst case scenario than the best. Having an estimate for the worst case is especially important for real-time applications.
There are several other measures, including the number of operations, the cost of data alignment, and the total cost of ownership. These are all important if you’re trying to build a high-performance computing system.
Apply an appropriate representation/implementation of a data structure in a given situation
One of the most challenging parts of designing a computer program is deciding which data structures to use and how to structure your information. There are many types of data structures that are suited to different applications. For example, a single variable based data structure is generally not suitable for dynamically changing data sets. In such cases, a more robust data structure may be necessary. The data structure of choice in such scenarios may be an abstract data type.
One of the most important considerations is the data structure’s size. This is particularly true if you plan to store massive amounts of data in your computer’s memory. Typically, data is stored in an array of sorted integers. But before you can go dumping all your data into an array, you will need to allocate a certain amount of memory. When it comes to memory allocation, efficiency is the name of the game. You can make your life easier by allocating your data structure to multiple memory regions in a given time frame. If you do not take care of this task, your code base will quickly resemble a chaotic jumble. A well-crafted data structure can also help your software function as designed by ensuring that each line of code performs its function.
A well-crafted data structure will not only enhance the user experience, it will also minimize the risk of data loss, which is one of the most common mistakes made by programmers.
Computer communications and the Internet
Computer communications and the Internet have become an essential part of modern information systems. These devices can communicate with each other, both over the air and through networking, and are used for many different applications.
The World Wide Web, for example, is a computer system that allows people to interact with hosts on distant computers. However, before the web was developed, a number of other technologies were in place. Those included electronic mail and telephone networks. In the early days, to access another server, you had to know its address and command the device to connect.
One of the first computer communication networks was ARPANET, which was built in the mid-1960s. It provided a vehicle for research into the design of distributed operating systems. As researchers expanded the range of applications, the technology of computers changed.
In the mid-1980s, the National Science Foundation (NSF) took over the management of the Internet. They also imposed restrictions on commercial ventures on the internet.
Eventually, the US government renamed ARPA to the Defense Advanced Research Projects Agency (DARPA). This agency is now responsible for research and development on defense and aerospace matters.
A large international community – the Internet Engineering Task Force (IETF) – is active in the area of networking and communication. Their work is done in working groups, or mailing lists, grouped by topic.
One of the most important principles of the Internet is the concept of end-to-end delivery. End-to-end delivery means that all of the packets that are sent and received are legitimate.
