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
A 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:
- An editor, which serves not only to write text but also to give it the desired format (size, typography, color, alignment…).
- A system for inserting photographs, audio and even video files. All these elements complement and reinforce the textual content.
- 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 Design Books
Web design is an area focused on the development of digital interfaces, such as the design of websites and applications. To do this, web designers create pages using markup languages such as HTML or XML.
It requires taking into account navigability, interactivity, usability, information architecture, and the interaction of media such as audio, text, image, links, and video. This process encompasses many areas, such as interface design, SEO optimization, and website design among other things.
The visual part of the sites is taken care of by CSS, a term used to style elements written in HTML. The process of creating sites can be done with tools such as Adobe Dreamweaver (which will require the professional to know more about codes) and CMS which are content management platforms, such as WordPress.
18) 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.
