50+ Computing Books for Free! [PDF]

Ever since mankind focused on facilitating work processes, work quality and productivity, advances in automatic information processing have not stopped. Such a vital area could not be left out of our virtual library that is why we present our large collection of computing books.

Today we can say that this scientific area affects all essential sectors of society such as transportation, telecommunications, health, education, business, information storage, process control, among others.

Computing is defined as the automated processing of information by means of computers. It is based on theoretical, practical and technological scientific knowledge that facilitates its main tasks. These are: storage, processing and transmission of data.

Computer science is divided into two main areas of development: the study and development of computer programs (logical element), called software; and, on the other hand, the physical structure of computers (physical element), called hardware.

Information processing basically consists of converting primary data into organized, meaningful and useful information. It encompasses image processing, data mining, cryptography, artificial intelligence, teleinformatics and bioinformatics.

Thus, this important scientific and technological area has facilitated the management of an immense amount of data and has become the basis for the creation of the Internet and communication technologies.

It is really difficult to find any social sector or discipline that is not affected by the advances of computing. It can be said that it has reached all public and private sectors, even domestic life.

The most important innovation in computing was the creation of the first computer by the German scientist Konrad Zuse (1941), the Z3 model, which weighed 1000 kg. It performed basic mathematical operations.

This was followed by the evolution to the personal computer in 1965, by the Italian company Olivetti, which today derives in personal computers, laptops, tablets and smartphones. Today, many cannot conceive of life without these electronic devices. This is how important this discipline is.

Its accelerated evolution in recent years has had a major impact on the lives of half of the world’s population that today has access to the Internet and at least one electronic device.

This is a consequence of being able to have immediate access to information, remote communication and to an incalculable number of transactions and operations that make life much easier.

If you are interested in this interesting subject, we recommend once again that you take a look at the computing books in PDF format, available in this section of our virtual library.

1) Artificial Intelligence Books

Artificial Intelligence (AI) is the combination of algorithms devised for the purpose of creating technologies that emulate characteristics or capabilities unique to the human intellect. The term was adopted in 1956, but has become more popular today due to increased data volume, advanced algorithms, and improvements in computing power and storage.

Artificial intelligence is developed from algorithms, which are mathematical learning capabilities, and the data needed to train the algorithms. The data is usually observable, publicly available, or generated in some companies. And the algorithms iterate over that data to learn from it.

Typically, an AI system is able to analyze big data, identify patterns and trends, and therefore formulate predictions automatically, quickly and accurately. For us, the important thing is that AI makes our everyday experiences smarter.

2) Automation Books

Automation is the set of computer, mechanical and electromechanical elements or processes that operate with minimal or no human intervention. They are typically used to optimize and improve the operation of a factory, but automation can also be used in a stadium, a farm or even in city infrastructures.

Today, robotics and computing have made it possible to increase the scope of automation. Machines are used in countless industrial sectors to automate processes.

Automation does not always mean replacing people. Sometimes it will happen, because some steps that require human interaction will be eliminated, but the advantages lie in productivity, standardization and efficiency. Thanks to the paradox of automation, not only is efficiency achieved, but human intervention becomes more important, albeit less frequent.

3) Big Data Books

The term “big data” refers to data so large, fast or complex that it is difficult or impossible to process using traditional methods.

The act of accessing and storing large amounts of information for analysis has been around for a long time. But the concept of big data gained momentum in the early 2000s, when industry analyst Doug Laney articulated the current definition of big data as the three Vs (Volume, Velocity, Variety).

As Big Data is something that never stops growing, the tools used to manage it evolve with it and are constantly being refined. Tools such as Hadoop, Pig, Hive, Cassandra, Spark, Kafka, etc. are used, depending on the needs of each organization. There are many, many solutions, and many of them are open source.

4) Blockchain Books

Blockchain is a technology created in 1991 by scientists Stuart Haber and W. Scott Stornetta by introducing a computationally practical solution to time-stamp digital documents so that they cannot be modified or manipulated,

It is a single, consensual record distributed across multiple nodes in a network. It is basically a system with which secure transactions can be made between people around the world without the need for intermediaries.

Blockchains can only be updated by the consensus of the majority of the system’s participants, which are called nodes and are in essence a computer arranged for these transactions. This information can never be erased or modified, so Blockchain is presented as an immutable and permanent record.

5) Books about Computing

Computing is the science that deals with the study, evaluation or expansion of technological and digital equipment. It is in charge of studying, expanding and understanding the processes of computers, in addition to the operation of peripheral equipment that can work with it.

It has a history of no more than a century, although sources claim that its beginnings date back to when machines or artifacts oriented to different calculation tasks began to be manufactured; in 1623, the first mechanical calculator was invented by a famous German mathematician named Wilhelm Schickard.

The scope of computing is incalculable, the modification in the processes of activities has already occurred and continues to advance in an unprecedented way, constantly transforming our lives and originating new personal requirements that demand us to be aware of these new resources.

6) Computer Networks Books

Computer networks or data communication networks refer to a series of computer systems connected to each other by a series of wired or wireless devices, through which you can share information in data packets, transmitted by means of electrical impulses, electromagnetic waves or any other physical means.

Computer networks can be classified in two different ways or types:
– According to their size into local area networks called LAN (small), metropolitan area networks called MAN (consisting of several LANs) and wide area networks called WAN (e.g., the Internet).

– According to the way the equipment is connected: line, bus, star and ring.

7) Computer Security Books

Computer security is the process of preventing and detecting unauthorized use of a computer system. It involves the process of protecting against intruders who use our computer resources with malicious intent or for profit, or even the possibility of accessing them by accident. Threats can come from malicious programs that are installed on the user’s computer (such as a virus) or that arrive remotely.

In the case of viruses, it should be noted that there is currently a very long list of viruses that can significantly damage any computer or computer system. For example, there are so-called resident viruses, direct-action viruses, encrypted viruses, etc.

Computer security consists of security measures, such as antivirus software programs, firewalls and other measures that depend on the user, such as activating or deactivating certain software functions.

8) Database Books

database is a collection of information pertaining to the same context, arranged in a systematic way for later retrieval, analysis and/or transmission. This term was first heard in 1963, at a symposium held in California, USA.

  • Among the main characteristics of database systems are:
  • Logical and physical independence of data.
  • Concurrent access by multiple users.
  • Data integrity.
  • Security of access and auditing.
  • Backup and recovery.
  • Access through standard programming languages.

For a Database to be truly functional, it must not only store a large number of records, but they must also be easily accessible. In addition, new information and changes must also be fairly easy to make.

9) E-Commerce Books

Electronic commerce or e-commerce can be defined as the economic activity that allows the trade of products and services from digital media, such as websites, mobile applications and social networks. The relevance of this type of commerce is such that companies take it as part of the sales strategy thanks to its efficiency.

These are the main business models in e-commerce according to the agents involved B2B: Buying and selling between companies; B2C: Sale of goods and services from companies to consumers; C2B: Individuals selling their goods and services to companies; C2C: Buying and selling goods and services between consumers.

Among the advantages of e-commerce is the possibility of accessing products from all over the world, which do not even have to be displayed to the public in a physical store. This allows the seller to save costs.

10) Excel Books

Excel is a computer program developed and distributed by Microsoft Corp. It is a software that allows you to perform accounting and financial tasks thanks to its functions, developed specifically to help create and work with spreadsheets.

In Microsoft’s first exploration in the creation of spreadsheets allowed to handle numerical data in a list constituted by the union of rows and columns, this was created in 1982, with the exposure of Multiplan. Giving rise 3 years later to the first version of Excel.

Excel is different from all other office programs because it allows us to work with numerical data. With the numbers we store in Excel we can perform basic arithmetic calculations and we can also apply more complex mathematical functions, or use statistical functions.

11) Hacking Books

Hacking is the set of techniques used to access a computer system by violating the originally established security measures.

Generally, when we talk about hacking we usually refer to illicit access; but hacking as such, is a set of techniques used to enter a computer system by violating the security measures, regardless of the purpose for which it is performed, it can be lawful and requested.

Ethical hacking, also known as white-hat hacking, in contrast to traditional hacking with criminal motives, focuses on programming weaknesses and software conceptual design (bugs). In the case of security testing, the focus is, among other things, on applications and web security. In addition to software, any hardware in use can be integrated into the system security testing process.

12) Operating Systems Books

The operating system is the software that coordinates and manages all the services and applications used by the user on a computer, making it the most important and fundamental. It is made up of programs that enable and regulate the most basic aspects of the system. The most commonly used operating systems are Windows, Linux, OS/2 and DOS.

The operating system is already installed on the computer and most people do not make any modifications to it. However, it is possible to upgrade or change it.

All operating systems use a graphical user interface. That is, the one that allows you to use the mouse to click icons, buttons or interact with any other element to perform actions or tasks.

Operating systems, also called kernels, usually work in a privileged way with respect to the rest of the software, without allowing any program to make important changes to it that could compromise its operation. 

13) Photoshop Books

Photoshop is the popular name for image editing software. Its full name is Adobe Photoshop and it is developed by Adobe Systems Incorporated. It runs on Apple Macintosh and Windows operating systems. 

Currently, it is one of the essential allies of any marketing team, especially in the creative branch, given its potential to create any type of graphic material with relative ease. It requires some learning, but its possibilities are almost endless.

Photoshop’s main functions are related to photo retouching, graphic design, illustration creation, web design, photo compositions and even video graphics. Its tools have become not only an icon of the program, but a de facto standard, so that all other image retouching applications now offer them as well.

14) PowerPoint Books

PowerPoint is a software whose purpose is oriented to the generation of presentations that include text, graphics, animations… It is part of the set of applications that integrate the package called Microsoft Office.

This program revolves around three main functions:

  1. An editor, which serves not only to write text but also to give it the desired format (size, typography, color, alignment…).
  2. A system for inserting photographs, audio and even video files. All these elements complement and reinforce the textual content.
  3. A system that proceeds to display all the content, whatever its type, in an absolutely continuous manner.

15) Programming Books

Programming is the process of taking an algorithm and encoding it in a notation, a programming language, so that it can be executed by a computer. Although there are many programming languages ​​and many different types of computers, the first step is the need for a solution. Without an algorithm there can be no program.

The programming language is a predesigned artificial language made up of signs, words and symbols that allows communication between the programmer and the computer.

The instructions that the computer follows to execute applications and programs are written in programming language and are then translated into a machine language that can be interpreted and executed by the computer’s hardware (physical part). The best known programming languages ​​are: Basic (1964), C++ (1983), Python (1991), Java (1995), C# (2000), among others.

16) Telecommunications Books

The concept of telecommunication encompasses all forms of distance communication. The word includes the Greek prefix tele, meaning “distance” or “far off”. Telecommunication is therefore a technique that involves the transmission of a message from one point to another, usually with the additional characteristic of being bidirectional.

It is a broad term that includes a wide variety of information transmission technologies, such as telephones (wired and wireless), microwave radio frequency communications, fiber optics, satellites, radio and television broadcasting, the Internet and telegraphs.

Telecommunications, as we know it today, had its first turning point in 1800, when Alessandro Volta invented the electric battery. The next major breakthrough was the electromagnetic telegraph developed by Samuel Morse in 1835 and then the expansion of the telephone in 1876 when Alexander Graham Bell obtained its patent in the United States. From then on, the advancement of telecommunications grew rampantly. 

17) Web Development Books

Web development is the proper construction and maintenance of websites, while expanding their content and improving their appearance with good performance, so that the user gets the best experience.

A web developer can be involved in the design of a website, but can also write web scripts in languages such as PHP and ASP. In addition, a web developer can help maintain and update a database used by a dynamic website.

Web developers are usually employed by companies specializing in specialized software development or computer consultancy. These professionals have the option of working directly for the company or on a freelance basis.
