The caret (dark vertical line) is at the position where the date and time of file creation is stored.

This is the message that you see when you try to run this executable under DOS (yes, Windows executables still start with a DOS program).Д¬loser to the bottom of the window, you see the characters вЂњPEвЂќ that denote the beginning of the actual Windows executable. You will notice that there is intelligible text: вЂњThis program must be run under Win32вЂќ. An example of translating dataД«elow, in the screenshot of HxD, we have loaded an executable file that adheres to the PE file format (the executable file format of Windows). In the following, we will have a quick look at the data inspector of HxD 2.0, to interpret data in a meaningful way. Another option is to use a structure editor or a data inspector. Some hex editors also scan the entire file for text passages and list all matches in a result window. Since you donвЂ™t always know where the text is located in a file, you can try the text search function. The rest of the file however will make little sense when viewed as text. So you have to know the position in the file where this text is stored and go to it.

When you canвЂ™t read anything there that makes sense, it means either this is no text or the encoding is untypical.Д®ven if you know the file format it doesnвЂ™t mean there is a text representation: imagine an image file like a JPG, this can never become English text, since it is a series of pixels, you will either see a picture rendering, or a sequence of color values.ДЄnother reason: files are often a combination of text and other data types like images, sound, or program code.

ThatвЂ™s what the right text column in a hex editor is for. Sometimes they directly translate to intelligible text because the text is encoded in a typical way. You have to know the data format to translate it into something that makes more sense to humans. Hexadecimal numbers first and foremost are just numbers. In other words: there is no general translation program for numbers to meaningful representations, such as text. It would be helpful if the textual representation could be so smart to interpret any data into something meaningful, but in truth it is just an attempt to show data as text assuming a common encoding. The essential information a hex editor shows is divided into two columns, which both show the same data but represent it in different ways: the left column in a hex editor shows the raw numbers a file is made of, and next to it, the right column shows a tentative textual representation. How do you know if the text representation on the right in a hex editor is valid? What are those вЂrandomвЂ™ numbers on the left in the hex editor? These or similar formulations seem to be popular variations of the above question:Д¬an I change the text to English (or another language)? WeвЂ™ll start with a brief answer to this question: how do I make sense of (hexadecimal) numbers in a hex editor? (This actually was one of the motivations for me to write such a program: to understand data and representations better.)Дata encoding, decoding and representation is a big topic, but for many applications of hex editors a few concepts are enough. But almost no program shows data in such a raw format, except for hex editors, which can make this concept pretty confusing and abstract. Understanding how to find the volume of a sphere allows you to tackle more complex equations, like the volume of a cylinder, pyramid, or cone.All data in a computer, including files, is a sequence of numbers. By plugging a radius into the sphere formula, you can determine its volume in cubic centimeters, inches, meters, or feet. Once you understand the parts of a sphere, itвЂ™s easy to see how to find the volume of a sphere. So, let's plug this in to solve for the volume of the sphere: Now that you know the formula, let's calculate the volume of the sphere below:

When you calculate volume, the result should always be cubic units - cubic centimeters, cubic inches, cubic meters, cubic feet, etc.ДЄs you can see, the volume equals 4/3 times pi times the radius of a sphere cubed. The volume of a sphere represents the amount of space it takes up in three-dimensional shape. No matter which direction the radius of the sphere points, its length will always reach the outside surface of the sphere. The radius r of the sphere represents how far away that given point is from the surface of the sphere. The center of a sphere is marked by a point, similar to the nucleus of an atom. Before determining how to find the volume of a sphere, you must first understand the structure of a sphere.
