A logo or logotype is a badge.
The dictionary of the Royal Spanish Academy (RAE) includes the term logo as a compositional element that means specialist with respect to what the first element indicates. For example: “Biologist” is a specialist in biology .
The most common use of the concept logo, however, is associated with the idea of logotype . It is a badge made up of letters and images , peculiar to a company , a brand or a product .
The logo usually includes some symbol that is almost immediately associated with what it represents. In ancient times, artisans marked the works of their authorship with a logo. Kings also crossed legal documents with a personal logo, either by hand or by means of a seal.
Types of logo
Generally, the notion of logo is used to refer, interchangeably, to a logo (the typographic representation), isotype (an icon or visual sign) or isologo (combination of logo and isotype). The logos of Apple (an apple), Nike (a pipe) and the Rolling Stones (a tongue) are among the most famous in the world.
For the logo to be successful (that is, to be associated with what it represents), it must be legible (in all types of sizes), reproducible (regardless of material conditions ), scalable (to the desired size), distinguishable (it must not give place to confusion) and memorable (it has to impact so as not to be forgotten).
The language that identifies The Rolling Stones is one of the most famous logos in the world.
A computer language
Logo is, on the other hand, a computer language created for educational purposes using Lisp and an American cable television channel aimed at the homosexual, bisexual and transgender community.
Regarding computer language , many current programmers remember it fondly for having been one of the first tools that helped them get closer to their vocation. It is important to note that this is a fairly old language, which was first presented in 1967, and was created by Saymour Papert, Wallace Feurzeig and Cynthia Solomon . In fact, it was already found on all personal computers with specific versions for each one before MS-DOS became popular.
Among the computer brands that we can cite as examples of the platforms for which Logo was adapted are Atari, Apple, IBM, Commodore and Texas Instruments . Nowadays it is considered a relic, which is of particular interest to people who have used it in their time, since there are much more complex and accessible tools to teach children to program; a specific example is the Scratch language .
Logo Versions
As no standard was defined for Logo at the time, there are a large number of different versions. Despite this, almost all of them present us with the same elements: through relatively simple lines of code, we tell a turtle represented by pixels to draw different figures on the screen. The more complex the commands become, the complexity of the drawings also increases, while in the background it also teaches us mathematical concepts that are very useful in the world of graphic programming.
The choice of the turtle as the animal to represent the cursor was not arbitrary at all, but was made in honor of a robot manufactured at MIT that responded to different commands to perform specific movements. The initial idea always remained intact: create a language that the little ones could easily use to see instant results after entering the instructions.
Logo allows us to execute simple commands , but also repeat them a defined number of times with certain alterations to obtain complex results. For example: place the turtle at a point x, y; rotate it 10 degrees; draw a straight line of extension e. If we repeat these three lines dozens of times, we will obtain a series of rays that start from the same point.
