What Is A "CPU"?Complete Information


Do you know what this CPU is? Why is it also called the brain of the computer? There are many questions that often trouble many people. Just like in our body, our brain controls all of our processes, so in a computer, the CPU also controls all the processes in and out of it, especially for this reason that the CPU is also called brain of the computer. It handles all the instructions given by the user, and it is above the capability of the CPU, how quickly and in what way they process those instructions. The sooner he can do it is called the better or efficient CPU.

As technology is progressing in the way, we need fast CPUs to process more and more complex processes, which can facilitate these complex calculations and handle multiple processes at once. , This thing is also called Multitasking. Specially, software and Hardware Developers are always engaged in making better CPUs as their demand also increases. Take an example to understand. When you go to buy a laptop or a desktop, in the shop then they tell you about some technical specifications such as 64 bit quad core Intel i7, or i5 etc. If you are not from the field of computer then you will not understand anything from it. But in the end what he is saying will not do anything at all. Do not be scared because today we are going to provide information about these technical specifications, Cores, CPU only.

Every 6 months you will come in the market with a new processor CPU look. It is also difficult for new users to choose from which processor they want to buy if they are buying a new system. Because you are required according to your work. In this case, if you have to do basic work then you do not need any more advanced CPU. Because your normal CPU for such tasks can do that work comfortably and you will not have to spend more money. But due to lack of accurate information, people always fall in the way of shopkeepers and buy more precious CPU which they never need. So today I thought why you should give people the correct information about what the Central Processing Unit is and how it works, so that you can easily choose the correct CPU. Then let's start without delay and know what the CPU is.

What is CPU
Do you know what is the full name of CPU? The CPU is full form! Central Processing Unit. This is a small piece of hardware that processes all the instructions in the computer program. It handles all the important functions of the computer system such as arithmetical, logical, and input / output operations. CPUs are built in such a way that the amount of billions of microscopic transistors can be kept in a single computer chip. With the help of these transistors, all calculations are done, which are used to run the programs that are stored in memory of the system.

The CPU is also called the brain of computer because - all the instructions, no matter how simple it is, all have to go through the CPU. For example, you type a alphabet such as L then it appears in the screen. It has the CPU hand to appear in the screen. For this reason the CPU is also referred to by the name of the Central Processor Unit, and in short, it is called processor. So when you are looking at a technical specification of a device in an electronic store, then the processor specification there is a CPU.

When we do discus about different types of CPUs, then by that we mean its speed. Like how fast he completes all the functions. We need speed to do our work, the faster our process is processed, the sooner we can do any new work. As we become our instruction complex such as 3D animation, editing of video files, etc., we need a much better CPU. Therefore, the technology behind all the technological advances has been the most important reason behind the processor technology.



We know CPU by name, such as processor, Central Processor, or microprocessor etc. Whatever the instructions it receives from your software and hardware, this process does whatever it is small. So this is a very strong part of computer.

Whatever advancements are there in CPU technology, one thing is given more importance to how transistors can be made smaller and smaller. This is because it can make those CPUs more efficient and their speed can be multiplied. For the first time about this thing, a scientist whose name is Moore, he said. So this thing is also called Moore's Law.

What CPU works
So let us know about some important features of Central Processing Unit (CPU)
  • The CPU is considered to be the brain of the computer.
  • The CPU performs all types of data processing operations.
  • It stores data, intermediate results, and instructions.
  • With it, it controls almost all operations of all parts of the computer.
How CPU works
You need to know what the CPU works. Well, we know that the CPU that works is very important but now we will know how this CPU works. So many improvements have been made so far in the past several years since the origin of the CPU. Despite so many improvements, the basic functions of the CPU are still beans. The basic functions of this are fetch, decode, and execute. Let us know about them in Vidarbha.

Fetch
As the word appears, the instruction is received in it. In this, instruction means that series of numbers is passed from the RAM to the CPU. Each instruction is a small part of an operation, so the CPU should know that the angle direction is coming next. The current instruction address is kept by the program counter (PC). Then the PC and instructions are placed in the Instruction Register (IR). After that the PC length is increased which can be used to refer to it at next instruction's address.

Decode
Once the instruction is fetched and stored in the IR, then the CPU passes that instruction into a circuit called the instruction decoder. It then converts that instruction into signals which are passed later on for further action by the parts of the other CPUs.

Execute
This is the last step in which the decoded instructions are sent to the relevant parts of the CPU to be completed. Then the results are often written in the CPU register, where they can be referenced by later instructions. Here you can understand them as the memory function of your calculator.

What are CPU Components
Here's what the components of a CPU are and what they work. By the way, there are three main components of the CPU.
  1. Memory or Storage Unit
  2. Control Unit
  3. ALU (Arithmetic Logic Unit)
Memory or Storage Unit
These store the units system's instructions, data, and intermediate results. These units provide information to all other units as well. It is also called internal storage unit or main memory or primary storage or Random Access Memory (RAM).

Its size affects its speed, power, and capability. Primary memory and secondary memory are two such memories which are present in the computer.

What are Functions of Memory Unit
  • It stores all the data and instructions needed for processing.
  • It stores all the intermediate results of processing.
  • This final results of processing are stored when they are not released in the output device, in the output device.
  • All inputs and outputs are transmit by main memory.
Control Unit


These units control the operations of all parts of the computer but they do not do any actual data processing operations.

What are Functions of Control Unit
  • It comes in handy for controlling the transfers of data and instructions that are used to transfer the computers to other units.
  • This is done to manage and coordinate all the units of computers.
  • They receive instructions from memory, interprets them, and those operations are used to direct the computer.
  • It communicates with Input / Output devices for data transfer and for results from storage.
  • It does not process anything or stores any data.
ALU (Arithmetic Logic Unit)
This unit consists of two subsections called,
  1. Arithmetic Section
  2. Logic Section
1. Arithmetic Section
The function of this arithmetic section is that all of these perform arithmetic operations such as addition, subtraction, multiplication, and division. All the complex operations are done using the above mentioned operations as a repetitive use.
2. Logic Section
The main function of this logic section is to perform all these logic operations such as comparing, selecting, matching, and merging of data.

Computer CPU types
As we know, the computer Central Processing Unit (which is called a CPU in short, is a very important component that handles all the instructions and calculations that are sent to it from other computer's components and peripherals. It also depends on the CPU, how powerful they are, so it is important that you choose the correct CPU so that they can handle all the tasks as needed. Is intel AMD, who have their own types of CPUs present.

Single Core CPUs
Single core CPUs are the oldest type of computer available in CPU and first of all these types of CPUs were used. Single core CPUs can only have one operation at a time, so these are not the right choice for multi-tasking. Whenever the user wants to run more than one application, their performance is greatly reduced soon. If you want to run another application then you will have to wait for the first one to finish. Otherwise the first operation will be very slow. In this type of CPUs, the performance of the computer depends mostly on the clock speed and also the measurement of power.

Dual Core CPUs
A dual core CPU is a single CPU but it has two cores and therefore functions like two CPUs. Where the processor in the single core CPU has to switch back and forth in different sets of data streams, if more operation is to be done then the dual core CPUs can handle the multitasking comfortably too. In order to take advantage of Dual Core, both operating systems and programs running in it, it is very necessary to write a special code, which is called a simultaneous multi-threading technology. Dual core CPUs are fast compared to single core but not like quad core CPUs.

Quad Core CPUs
Quad Core CPUs further refinement consists of multi-core CPU design and four cores are feature in a single CPU. Like a dual core CPUs are split into the workload, within the two cores, exactly the same quad cores can do large multitasking functions in even greater amounts. It does not mean that one operation will be four times faster. It is only possible by having SMT Code. Speed in these CPUs are not noticeable. But yes, users who have to do a lot of heavy tasks such as Video Editing, Games, Animations, etc. together, these CPUs will come in handy for them.

How important are the CPUs?
As I have said beforehand how important a CPU is for a computer. Since it is also called brain of computer, you must have understood how important it is. Because it is solely responsible for executing the commands within the program, the more CPU capacity, the more likely it can run their applications.

What is CPU Cores and how many Cores are there in CPU?
Before the time of computing, then the CPU used to be single core. This means that the CPU was limited to only one set of tasks. Due to this very reason, the speed of computing was very low in earlier computers and they used to take more time to do the work. But due to the need for more computing power over time, manufacturers had to rely on new approaches to increase performance. And while improving the performance, multi-core processors were born. Nowadays we are listening about dual, quad, and octo-core CPUs.

Dual Core Processor:- In a dual-core processor, two separate CPUs are present in a single chip. By increasing the number of cores, CPUs are able to handle multiple processes simultaneously. This gives manufacturers more performance and less processing time according to their requirements. With the introduction of Dual-core, it is further helpful in developing quad-core processors that contain four CPUs. Similarly octo-core processors too.

What is Hyper Threading?
Some CPUs generate the ability of more cores by virtualizing their existing physial core. This process is called Hyper Threading. For example let's use Single core to virtualize it like a double cores. Dual cores can be done even with the single core.

Virtualizing means that a CPU in which a core is present, but it functions like a dual core. Here, the extra cores mean that there are separate threads. But here we should know that physcial core performs much better than in virtual cores.

What is multithreading?
Thread is considered as cores here. You can consider a single thread to be a single piece of computer process. That means Multithreading means processing more threads together. Meaning, a number of instructions in a single CPU can be understood and processed at the same time. This allows CPU core to process more work together at the same time. By which computing speed is greatly increased.

Intel Core i3 vs. i5 vs. i7
Let's know about Intel's different CPUs. How do these processor work. You must be thinking that Intel's i7 processor performs better than i5 and i3. And this is also true. Since i7 is much better i5 and i5 is better than i3. But do you know why these processors are different from each other and different from each other in terms of performance. But it is easy to understand, let's know about it.

Intel Core i3 processors are dual-core processors, the i5 and i7 processors are quad-core.

With features like Turbo Boost, i5 and i7 chips work much better. This allows the processor with turbo boost to help its clock speed exceed the base speed, such as 3.0 GHz to 3.5 GHz, whenever they need it. But Intel Core i3 chips do not have these features.

Those Processor models whose ending is written "K" can be easily Overclocked, which means that additional clock speed can be forcefully and can be utilized at the time of need.



Hyper-Threading, as I've already told about it, enables it to process two threads together in each CPU core. This means that i3 processors in which Hyper-Threading supports four simultaneous threads (because they are dual-core processors) can be processed together. At the same time, Intel Core does not support i5 processors Hyper-Threading, it means that they can also work at the same time with four threads. Only i7 processors support this technology (since it is quad-core) so they can process 8 threads at a time. Since many devices have the power constraints, which do not have continuous supply of power, all the processors, whether they are i3, i5, or i7, have to balance their performance and power consumption.

How does the CPU look and where does it lie?
An modern CPU is usually smaller and square shaped, in which many of the short, rounded, metallic connectors are attached to the bottom. But some older CPUs contain pins in place of metallic connectors. The CPU is directly attached with the CPU "socket" (or sometimes a "slot") which is in the motherboard. The CPU is inserted in the socket pin-side-down, and a small lever helps to secure that processor.

Because the CPU has to do a lot of processes together, so due to some time run these modern CPUs are mostly Get hot Therefore, to remove this heat it is necessary to attach a heat sink and a fan directly to the top of the CPU. Typically, it comes bundled with a CPU that you must buy.

Talk about other advanced cooling options, you can use water cooling kits. Keep these special care while installing these CPUs because its pins are very sophisticated.

What is CPU Clock Speed?
Clock speed of any processor is called where a processor can process how many number of instructions in a second. It is measured in (GHz).

For example if a CPU's clock speed is 1GHz then it means that it processes the same instruction in one second. If one CPU's clock speed 3.0 GHz then they can process 3 billion instructions in one second.

What are the CPU Advantages
By the way, there are so many advantages of CPU in a computer. But here we will only talk about a few advantages.

Fast Calculation of Mathematical Data
The primary advantage of a computer processor or a CPU is that this allows you to calculate fast mathematical data. This is a very important reason why computers are ahead of humans in some tasks, for example mathematical modeling. Depending on the same fast calculation of mathematical data, many tasks can be done in the computer such as video game, photo editing etc.

A Dynamic Circuit
An modern computer processor is basically a dynamic circuit. There are tiny switches in the amount of crores that are called transistors. Other components of the processor control the configuration of these tiny switches according to their input data or from the active application. This tiny switches produce large and complex dynamic circuits, such as in printed circuit board (PCB), in electronics. Similarly, a computer can emulate the function of another electronics.

Basic Computer Functionality
A primary base of any computer is a processor. All other hardware components are built according to the processor. Without this the other hardware and software of the computer is exactly pointless. All input and output peripherals solely depend on the processor for input and output of data. Because through the same processor the input data is processed and reaches the output. This is the processor where the computer computes anything.

What is the Importance of Computer CPU?
In all the computers that you can see in your office, you have a very important thing in it, called Central Processing Unit, or a CPU. This CPU performs all types of arithmetic and logical decisions that too in the speed of the second on billions of operations. Most computer components of the computer serve the CPU and fetch data by doing, storeing and displaying results in the end screen. So let's look at some of its functions.

Calculations
A CPU does all basic arithmetic such as addition, subtraction, multiplication and division in very high speeds. Since complex math functions are simple arithmetic of long chains, your computer can also fast these trigonometry, logarithms and other hard math problems. For example, the CPU of your computer can calculate hundreds of spreadsheet cells in some fraction of a second.

Logic
The CPU performs many logic decisions on the basis of simple comparisons, such as greater-than-condition, less-than condition and equal-to condition. Then, according to the outcome of the CPU comparison, your action takes.

Moving Data
The CPU puts in a lot of time to move data from one place to another. For example, reading a file from a hard drive, doing some calculation in the data and writing it later in another file.

Multitasking
The CPU can easily make "multitasks," for which it has to switch to different types of programs. And priroty has to work accordingly. This makes full use of CPU memory. Multitasking can work very well simultaneously with a lot of work off, without closing any task.

CPU's license
As the advancement in technology is happening. Similarly, there will be many such advancements in the CPU as if the superconductor graphene is used in place of Silicon or along with it.

Every year CPU's size is gradually decreasing. Such as the latest generation of Intel architecture has been manufactured in 22 nanometers (nm = 1 billionth of a meter). It is being heard that the next generation CPU is less than 14nm only. Power consumption can also be reduced by being smaller and additional cores can also be added to the CPU, hence Moore's law can also be kept intact.

Gradually these sizes seem to be continuously decreasing. But as small as this, but the size of the atom of Silicon will be bigger as it can not be smaller than that. Then it is pointing to this that a new thing can be used soon in place of Silicon.

Maybe that thing graphene? Because it is very small size. Extremely thin, is one of the thinnest known ingredients. This will help scientists in reducing the size of the CPU. IBM has reported that they have developed a graphene "transistor" that can also work in 300GHz. The way technology is being used, it is clear that Graphene CPU usage in the CPU industry can be found very soon. The time will tell only what changes are coming in the next CPU.
