In this article, we covered “What Are the parts of CPU (central processing unit)<\/strong>\u00a0and their functions<\/strong>”<\/p>\n Clear and Easy Processor Definition<\/strong> or CPU Definition<\/strong><\/p>\n What are the Processor and Process?<\/strong><\/p>\n It makes logic that whatever work you give to someone, if he does it, then we say that the process. Processors are processes to a command\u00a0given by you.<\/p>\n If you add a number on the calculator, the calculator rapidly adds it and shows it on the display. The process that does arithmetic is called a process. Simple, called process. Now the processor who procedures this work called the processor. The chip that calculates the calculation inside the calculator is called a processor.<\/p>\n The processor is a small chip attached to the computer’s motherboard. Which is also a\u00a0microprocessor? Its work is straightforward. This chip works in input and output. Now, what are this input and output? The input is command what you give to your computer or receive from the active software application on screen and background. The output is what you take from the computer with the given\u00a0instructions and running applications. It’s clear now. We will go deeply next.<\/p>\n The processor called CPU is a central processing unit<\/strong>. The CPU is in the center of the motherboard. It is easy to detect because the cooling fan, which looks on the motherboard, is just above the CPU. The only reason for applying the cooling fan above the CPU is that it quickly heats.<\/p>\n There are 3 workings in the CPU that contain two operative components and one is a memory. CPU has a primary component ALU (Arithmetic Logic Unit), and the other\u00a0is CU (Control Unit)<\/p>\n Nowadays everyone wants speed in a fast-growing life. Computer speed or processor speed is also one of them. That’s why everyone checks their speed before purchasing those who need a fast computer. Processor speed: The speed of the processor which shows how much processor can process work or task in a cycle. The speed of the processor measured in megahertz or Gigahertz. All processors coming out today express speed at Gigahertz.<\/p>\n Now, what are Gigahertz and Megahertz? It’s not complicated.<\/p>\n Hertz <\/strong>means the cycle.<\/strong><\/p>\n Megahertz <\/strong>measured in millions. Megahertz = one million cycles<\/strong>, 1000000 cycles.<\/strong><\/p>\n Gigahertz <\/strong>measured in Billions. Gigahertz = one billion cycles, 10000000 cycles.<\/strong><\/p>\n CPU operates on three things. First Fetch<\/strong>, Decode<\/strong>, and then Execute<\/strong><\/p>\n Fetch\u00a0The<\/strong> input instruction that the CPU\u00a0first gets stored in the RAM memory. After that, this input instruction fetches from the memory, meaning input instruction taken from the memory. It measures this input instruction\u00a0in numbers in memory, which means whatever input instruction will come in memory, it is in the numbers. Like 0 and 1 in which also called binary language.<\/p>\n Decode: <\/strong>Decode means understanding something and then verifying it. This work is of a CPU circuit. There is a circuit in the CPU,\u00a0which is called an instruction decoder. That circuit works on decoding. CPU understands that input instruction and then sees what to do on it.<\/p>\n Execute: <\/strong>When the instruction has decoded, then it is ready for the next step. The next step is execution. Now it must see what the instruction is. If this is math instruction, then it will execute for ALU (Arithmetic Logical Unit). Even if it is the direction of comparison, it will also execute for ALU but ALU will not give any result here. The work of executing is to send the instruction forward, which will work and it will find the result.<\/p>\n If seen, the above CPU operation<\/strong> and the components of the CPU<\/strong>\u00a0are very easy to understand how the CPU works<\/strong>. But let us take a further example of how CPU works. The work is to fetch and decode is in the Control Unit, and the execute work that happens is in the ALU<\/em><\/strong>.<\/p>\n Cache memory is the memory that stores any data for a limited time. When you work on a video project, video editor software\u00a0load video clips and audio from hard drive<\/span>, and it loads to RAM memory. Because of\u00a0the high speed of RAM memory, video clips load quickly in the video editor, preventing time and Lag during importing and editing.<\/p>\n The memory installed in the processor is actually three types of,\u00a0and we write these three at the level. which we call L1 cache memory, L2 cache memory, and L3\u00a0cache memory. If you want to know in full details about cache memory, then we will advise you to read it full What is Cache Memory<\/a> Article.<\/p>\n The first CPU chip had the only one processor unit in it, which means CPU can only work one process. But in today’s chip (CPU), over one processor is working, which we call processor core.<\/p>\n If two<\/strong> processors are working on the CPU,<\/strong> then it is a\u00a0Dual Core Processor CPU<\/strong>. Dual means the two.<\/p>\n If four<\/strong> processors are working, then it is called Quad-core CPU<\/strong>, and so on<\/p>\n Two Processor in CPU = Dual Core Processor<\/p>\n Four Processor in CPU = Quad Core Processor<\/p>\n Six Processor in CPU = Six-Core Processor or Hex Core Processor<\/p>\n Eight Processor in CPU = Octa-Core Processor<\/p>\n Ten Processor in CPU = DECA Core Processor<\/p>\n Now, what does the processor compute meaning in the\u00a0CPU?<\/p>\n The Two core processor of 2.93 GHz will work on the speed of 1465 Mhz.<\/p>\n One core 1465 Mhz.<\/p>\n Two Core Processor = 1465 X 2 = 2930 Mhz or 2.93 GHz<\/p>\n The processor works on two types of bit, one contains a 32\u00a0bit one is 64 bits. Now, what are these 32 bits and 64 bits? What are the differences between 32 bits and 64 bits?<\/p>\n 32 Bit:<\/strong><\/p>\n If we talk about hardware, a 32-bit processor is associated with the architecture. 32-bit processor means to store 4,294,967,296 values.<\/p>\n How it came to value now is 4,294,967,296?<\/p>\n See<\/p>\n 1 bit = 2 Value<\/p>\n 2 bit = 4 Value<\/p>\n 3 bit = 8 Value<\/p>\n 4 bit = 16 Value<\/p>\n Now, the value doubled on every bit. If multiplied by such a 32 bit, the value will be 4,294,967,296.<\/p>\n If we read this in technical language, then it gets 4,294,967,296 decimal numbers of 32 bits.<\/p>\n CPU always stores the data in the numbers and resolves the data in numbers only. As we have also written above, CPU takes the numbers from the memory.<\/p>\n 32 Bit Operating System – The 32-bit operating system can run on 64-bit systems. Because 64-bit architecture supports software of 32-bit. But 64-bit software or operating system can\u2019t run on 32-bit processors. 32-bit architecture is designed for 32-bit software and operating systems.<\/p>\n 64 Bit: <\/strong><\/p>\n Like this, 64 bits can store 18,446,744,073,709,551,616. And one thing, 64-bit CPU can transfer 64-bit data to a Clock Cycle<\/strong>. Here, 64-bit processors can now run the 32-bit software and operating systems. After 2010, it made all the operating systems and software\u00a0from 64-bit technology.<\/p>\n What is the difference between 32 bits and 64 bits?<\/p>\n If we talk directly, then it is possible to run the RAM up to 32-bit 4 GB. If 16 GB RAM is on the computer, then 32-bit architecture will only read 4 GB Ram.<\/p>\n It forms the small transistors in the processor in the nanometer, which comprises the other transistor with a transistor. Do not understand? Interconnect from one transistor to another transistor is called nanometer technology. Nanometer measures the height of the metal gate and pitch of gates.<\/p>\n The smaller the nanometer, the faster, and the best performance will be CPU<\/strong>.<\/p>\n The generation of processors shows which architecture is working in the processor. As the generation changes, the size of the architecture and the processor’s performance changes. Generation can be read and seen in the Intel company’s I series processors like i3, i5, i7, i9.\u00a0The processor generation has the same difference as the architecture that works in the processor.\u00a0What is Computer Generations?<\/a><\/p>\n About how many CPU types we have talked about in the CPU core or processor core. The CPU types are those like 32 bits 64 bits, a single\u00a0core and dual core, and other we wrote above.<\/p>\n But here Talk about the processor’s company<\/p>\n First Invented Processor<\/strong><\/p>\n The first Intel company\u00a0launched its first processor in the market. This time was November 1971. The company named the processor Intel 4004<\/strong>. Intel engineers Ted Hoff, Federico Faggin<\/strong>, and Stan Mazor <\/strong>made it. It was a single chip processor that used to work on 4 bits (Bit has explained above). There were 2300 transistors in this processor, which used 60000 operations in one second.<\/p>\n (Now you will not go into more details here, who had created a processor where they were born, what did they read, what had done in their life, etc.).<\/em><\/p>\n Then the Intel company started its second processor named Intel 8008 processor<\/strong>. After 8008, Intel launched 8080 processors<\/strong>. The same list is very long.<\/p>\n AMD Processors<\/strong> Company started its Microprocessor AM 386<\/strong> in March 1991. Its clock speed ranged from just 20 MHz to 40 MHz. In today’s time, this speed sounds like a fun. But the speed was too much to work.<\/p>\n If you talk about processor comparison, then the AMD processor<\/strong> and Intel processors<\/strong> both offer the best feature at their own process.<\/p>\n So far, whatever has written above was written in different parts of the processor.<\/p>\n GPU (Graphics Processing Unit):<\/strong> We will not talk about it deeply. So far, the computer processor has talked about. After that, in the computer world, there is a GPU called the Graphic\u00a0Processing Unit. The display on the screen, show transparency;This is all the work of the graphics processing unit. Small pixels on that screen, the GPU is the only thing to show full display. It is installed separately on the computer.<\/p>\n SOC Processors (System on Chip)<\/strong><\/p>\n The system on the chip only works on laptops or mobile phones. Components that are used on the computer do all the different things. The processor works differently; the Ram works differently; the GPU works differently; the modem works differently, the hard disk works differently.<\/p>\n However\u00a0, this does not happen in the SoC chip. In the SoC chip, all the components fitted on a single silicon chip, which also consumes less space and, also electricity. Mostly this chip is used\u00a0in mobile phones. That is why it called a system on a chip. The whole system mounted on a chip.<\/p>\n If there is still any question left in the mind, then go to the page of the Question Answers and see the answers to all the questions about it.<\/strong><\/p>\n \u00a0<\/strong><\/p>\n","protected":false},"excerpt":{"rendered":" In this article, we covered “What Are the parts of CPU (central processing unit)\u00a0and their functions” Clear and Easy Processor Definition or CPU Definition What are the Processor and Process?
