An important component of any computer software is how it stores information or data. A program can store large amounts of information in many ways, but one way to organize this information is called the hierarchical structure. This article will go into detail about these organizational structures and what each one means for your computer software.

Hierarchical structures are also referred to as trees or folders. To give you some context, think back to school when you were young where every student had their own folder with notes and assignments in them. That was a tree!

Data organized in a hierarchical system have a parent node and child nodes under that parent node. The parents and children can contain more sub-nodes and so on until there are no longer levels. These levels form a networked pattern which makes accessing specific pieces of information easy.

This article will focus only on explaining how binary files work in x86 architecture and not anything else like.EXE files or MySQL databases. When working with applications that create and use binary files, you will need to know how they organize their data.

Disclaimer: We do not represent that reading this article will make you an expert at organizing hierarchies in file systems. There are plenty of sites out there who teach you how to do this and we suggest looking up some information after reading to learn more.

The CPU registers

Another important part of the x86 architecture is its register system. These are specific storage areas within your computer used to store information.

The most well-known register is the one we mentioned before, the one that contains the instruction pointer. This is what tells the processor which piece of code to execute next. Computer programs often use this register to save or pass around data.

Other common registers include those for saving and retrieving different parts of an internal calculation, like multiplication tables or algorithms. There can be several hundred registers in total!

You probably already know some of these, but there are many more than just three.

Program memory

Memory that computer programs use to store information is referred to as program memory or code storage. This type of RAM is very important because it can be used to save, create, and run software applications!

Computer programs are made up of various chunks of data which are called variables. These variables may contain text, numbers, other programs, or even pictures and sounds. Programs often need to refer to these pieces of data during execution so they have a place where this data is stored while the program is running.

The most common way to understand how computers work is by thinking about them in terms of logic. When a computer does something, it compares an input with another piece of information, determines what should happen next, and then executes the appropriate steps. The same goes for programming!

A basic element of computing is using registers to do this comparison and storing results somewhere else. A register is part of your computer’s hardware structure that helps you manage and process information quickly. Registers make doing math faster, for example, by saving the result of a calculation until later when it can be put into action.

There are several types of registers in computers, but one of the most important ones for understanding x86 architecture is the general purpose (or integer) register. General-purpose registers hold integers — pure numbers without any fraction or decimal points. They also count towards your total number of registers depending on what kind of tasks you ask them to perform.

Instruction memory

Instruction memory is another important part of every CPU that executes computer programs. This space contains all of the instructions for a program, or at least the portion of an instruction stream that has just been executed.

Each core of modern CPUs have very large caches to store this information. These caches are much faster than main memory, so most of the time they do not need to look up instructions in RAM. Because of this, it does not matter too much how fast RAM is, as long as there is enough cache to keep up with the speed of the RAM!

The size of the cache varies per processor architecture, but many have shown that having more cache means better performance due to being able to execute more quickly.

The stack

Another important part of any computer is the stack. A stack is like an area in memory that contains information used for storing data. This information includes items such as variables, unfinished conversations, and documents you are working on at a given time.

The size of the stack can vary depending on how much memory your computer has. It also depends on what kind of applications you have running at one time. If you have a word processing program open then there is less space to use for the stack than if you only have internet browsing software open.

Usually the more apps you have open, the smaller your free stack space will be. That’s why it is important to close out every app properly and cleanup your computer when you are done using it!

There are two main types of stacks used by computers- heaps and frames. Heaps are larger than frame stacks but they are not quite the same size. Frame stacks are just large enough to hold the current activity until everything is closed down.

Heap stacks do not have this restriction. They can grow very large dependent on what programs you have open at one time.

Temporary registers

In addition to the general use of registers for storing information, x64 processors have several special purpose registers. One such register is known as the ESP (Extended System Programming) register.

The name “ESP” comes from early computer architectures that used this feature. The first computers had very little memory, making it difficult to store large amounts of data.

By having an extra byte-size register called the extended stack pointer, programmers could create space within RAM to save temporary variables. Because these variables are always eight bytes wide, they get their own dedicated register just like the generalpurpose registers.

This way, there is no need to allocate memory outside of the processor for small tasks. Once the task is completed, the saved data can be written back into the main memory location using the normal stack mechanisms.

The CPU registers

Another part of the x86 architecture is its register set, or what we refer to as the CPU registers. These are similar to your body’s internal system, such as your lungs that work together to breathe air in and out- only here it’s computer software instead!

The number of general use registers in an x64 processor like yours has grown quite large. Some people even have a separate register just for leaving messages because they feel like it! (I’m looking at you, SMS.)

But not all CPUs had many registers when computers first came about. In fact, some early processors didn’t even have any! This made storing information beyond the scope of the program difficult, if not impossible.

Luckily, though, engineers realized how frequently data needed to be accessed again after being used before, so they included a few special registers to hold this information. Over time, these became more common and were given unique names to better describe their function.

We will now go over the different types of registers in detail and see why they exist. Then, we will talk about which ones most programmers typically use in Intel 64 bit processors.

The CMOS memory

Another important component of most computers is what we refer to as the computer’s “memory.” This is how the computer stores information it receives from outside sources, and also store data that the processor uses to perform its tasks.

The most common type of RAM in use today is something called static random access memory (SRAM). SRAM is very expensive per bit, but the price comes down as you have more than one piece!

A typical motherboard will come with at least 2-4 gigabytes (GB) of DRAM (dynamic random access memory), which is much less expensive per byte than SRAM. However, DRAM is not guaranteed to retain its charge for very long before it needs to be refreshed.

This refresh process can take anywhere from milliseconds to minutes, depending on the size of the chip and the frequency at which it is being used. During this time, the CPU cannot do anything other than wait for the refresh to finish!

By having both types of RAM in your computer, the OS and software can choose whether to put new information into fast, inexpensive RAM or larger, slower RAM.

The program memory

Another important part of any computer software is its “program” or executable file. This is what users run to do something specific with your device- like use Microsoft Office, for example.

The way this works is that when you start up a new instance of an app, it contains the same files as the previous one. Only then does it get replaced by newer versions, if needed- which is why most apps have a setting to keep backups so you don’t lose too much work!

However, beyond those three main parts (which we will discuss in more detail below), there are some other components of computers that people rarely think about. One of these is how data gets stored after a program has finished running.

We talked before about how RAM is used to store temporary information, but not all programs need to have access to everything at once. An office suite, for example, typically doesn’t want full access to every document, font, and spreadsheet file going forward- just while it’s open.

That’s where the Operating System comes into play. By adding layers called “layers” or “hierarchies” of storage, it can give each individual application their own space to save things in. These additional layers are what allow us to easily move documents around without worrying about losing them forever.
