Let’s begin with a little CPU history.
Nowadays, you can’t mention CPUs without talking about Gordon Moore.
Gordon Moore
Gordon Moore was an American electrical engineer who co-founded Intel Corporation and is best known for Moore’s Law, which states that the number of transistors in a chip will double every two years.
It also says that this doubling will somehow make computers faster and more efficient as time goes on!
A Beginner’s Guide: Central Processing Unit (CPU)
This guide will go over what a CPU does and what it is made up of, as well as a few other details about different types of central processing units.
Introduction: CPUs are used Everywhere
Every business is using at least one server.
Servers are powerful computers that give out information to other computers.
The server has a central processing unit, also known as the CPU, which controls all of its functions and many people refer to it as the brain of the machine.
What does the CPU do?
The primary function of the CPU is to communicate with other CPUs in order for them to share information or data, such as who’s logged onto which account at any given time.
It also handles tasks like inputting commands from keyboards so they can be executed by programs or accessing files on hard drives so they can be read by an operating system.
Much more goes into every aspect of how CPUs work and how they work together to ensure a server performs at its best.
CPUs have evolved from being composed of many printed circuit boards that communicate by a complex string of switches and levers, to being the size of a thumbnail or even smaller with billions of microscopic circuits etched into silicon wafers.
So what does all this mean for the average person?
It means that CPUs enable computers to connect with one another and to communicate with users!
This has changed the face of the internet, allowing us to use things like email, cellphones, and social media and allowing for more sophisticated programs like video games and even virtual reality online worlds.
All this would be impossible without the CPU at the center of these elements working together.
The next time you’re browsing the internet or playing games on your computer, think about all that goes into it and how much more advanced computers are now than they were even a decade ago!
What are the Basic Types of CPUs?
CPUs come in all shapes and sizes, but the three most common types are single-core, multi-core, and heterogeneous.
A single-core CPU has one processing unit, while a multi-core CPU has two or more. This means that a multi-core CPU can handle multiple tasks at once, which is ideal for servers that need to do a lot of things at once.
Heterogeneous CPUs are a bit different in that they have multiple processing units, but each one is specialized for a specific task.
For example, one might be good at handling graphics while another is good at handling mathematical calculations.
This makes them perfect for devices like smartphones and tablets that need to be able to handle different things at once.
What is a Xeon Processor?
A Xeon Processor is a brand name for a type of CPU, specifically those that are intended for use in servers. They are manufactured by Intel and come in a variety of different models, each designed for different purposes.
Xeon processors are high-end CPUs that offer more performance and reliability than their Core i7 or Core i9 counterparts. This makes them ideal for use in servers where stability and uptime are key considerations.
They support dual-channel DDR4 memory and have up to 22 cores, making them well-suited for heavily threaded applications or those that require intense multi-tasking.
Xeon processors also feature Intel’s Advanced Vector Extensions 2 (AVX-2), which can deliver up to 2x the performance of AVX.
Compared with earlier generation processors, Xeon processors also provide up to twice the bandwidth for floating-point operations per clock cycle.

What is a 32-bit versus a 64-bit Processor?
A 32-bit processor can handle a certain amount of data at one time, while a 64-bit processor can handle more. This is why 64-bit processors are often used in servers- they can handle more data at once and keep things running smoothly.
32-bit vs 64-bit processing is a little confusing because it has to do with the amount of data a processor can handle.
Previously most processors were 16 and 32-bit, which means that they only use 4 GB of RAM at one time- anything over that won’t be used. However, this also means that its maximum potential throughput is limited.
A 64-bit processor, on the other hand, can address more memory because it uses double the amount of bits to do so. This means that its maximum potential throughput is much higher, which makes it ideal for servers where large amounts of data are being processed simultaneously.
64-bit processors are becoming more common in smartphones and tablets as well, which is why you often see devices offering more than 4 GB of RAM.
What is a RISC processor?
A RISC processor is a type of CPU that is designed to be low-power and efficient. They are often used in devices like smartphones and tablets because they don’t require a lot of power to run and they can handle multiple tasks at once.
RISC processors are based on a reduced instruction set computing (RISC) philosophy, which means that they only use a limited number of instructions that are easy to decode. This makes them fast and efficient, which is why they are often used in devices where battery life is important.
Some of the most popular RISC processors include the ARM Cortex-A53 and the Qualcomm Snapdragon 835.
What is a GPU?
A graphics processing unit (GPU) is a specialized electronic circuit that is designed to rapidly render graphics. GPUs are used in devices like smartphones, tablets, and gaming consoles to improve the performance of their graphics.
GPUs can be divided into two categories- dedicated and integrated. Dedicated GPUs are those that are separate from the rest of the system and are used solely for graphics processing. Integrated GPUs, on the other hand, is part of the system’s main processor and share resources with it.
Dedicated GPUs tend to be more powerful and efficient than integrated GPUs, which is why they are often used in devices like gaming consoles and high-end laptops. Integrated GPUs are more common in devices like smartphones and tablets, where their power and efficiency aren’t as much of a priority.
What is an ALU?
An ALU (arithmetic logic unit) is the part of the computer where mathematical and logical operations are performed.
Every CPU has an ALU, which contains two separate units: a control unit and a datapath.
The control unit defines what operation to perform while the datapath controls how it is done.
For example, a CPU with an ALU might add two numbers together by sending them to their respective units and then combining the results in a third, separate unit.
This process requires several steps that must be coordinated by the control unit.
What is a thread?
A thread is a sequence of instructions that can be executed on a CPU. In most operating systems, each program has at least one thread- this allows it to perform multiple tasks simultaneously.
In Linux, for example, you can run two processes at once by assigning them different threads.
This is often referred to as multitasking.

2. It also handles tasks like inputting commands from keyboards so they can be executed by programs or accessing files on hard drives so they can be read by an operating system. Much more goes into every aspect of how CPUs work and how they work together to ensure a server performs at its best.

4. This has changed the face of the internet, allowing us to use things like email and social media and allowing for more sophisticated programs like video games and even virtual reality online worlds. We have a smartphone that can do so many things. All this would be impossible without the CPU at the center of these elements working together.
