What is a CPU, know everything about it.

A CPU is the core of every machine. IF you are a laptop or a desktop user then you might know how important the Processor is. When buying a new laptop of computer it is very difficult to choose what processor to choose from.

There are a lot of CPU variant and sometimes it can be very difficult what to choose from. Whether a quad-core or a dual-core, i3,i5,i7 or i9. Knowing the difference and which to buy can really help you and I am here to do just that.

A Central Processing Unit (CPU)also referred to as the brain of the computer is one of the most important parts. The CPU is responsible for all the calculations and the arithmetic operations done on the computer. The CPU works in Fetch, decode and execute cycle. A CPU fetches instructions from the instruction from the ram. It then decodes the instructions and then after processing it displays the output.

 HOW DO CPU'S WORK

The working of a CPU is done in a three-step process. First, an instruction set is fetched from the memory in certain bytes.

NOTE: IF you have a faster processor suppose the latest intel i5 and older ram variant then no matter how fast you processor is if the ram fetches the instruction to the CPU at a lower rate the CPU will never be at its top speed, so it is very important for you to have a faster RAM variant too.

After the CPU has fetched the data then it process and executes on the data and then delivers the output.

 

WHAT IS A CORE IN A CPU.

As of this date, the latest is 6 or 8 cores in a CPU. That is a very huge computing power for a processor. But a lot of people have no idea as to What a core is? When the first processors came out they were large in size and they had only one single-core as a result of that the computing power of the CPU was also slow and then less amount of work could be carried out. Soon scientists started to enlarge the boundaries of the processor and the came out with faster processors.

Soon dual-core CPU's came out, essentially it means the there are two CPU's on a single chip. For a quad-core CPU would mean there are four CPU's in a single chip. With the advancements in technology, the processors become more powerful and were able to handle larger and bigger tasks and perform a variety of operations. The more the core the better the performance.

With Hyper-threading your computer can perform tasks as if would have more than 14 cores.

What is the difference between 32-bit and 64-bit processors?

A lot of people have no idea what a 32-bit processor and how 64-bit is a better choice or not. The two types of 32-bit and 64-bit. This processor tells us how memory a processor can have access from a CPU register.

A 32-bit system can access 2³² memory addresses, i.e 4 GB of RAM or physical memory.

A 64-bit system can access 2⁶⁴ memory addresses, i.e actually 18-Quintillion GB of RAM. It can handle any amount of RAM higher than 4GB.

The major difference between 32-bit and 64-bit processors is the number of calculations it can perform per second. 64-bit processors can come in many variants like dual-core, quad-core,octa-core versions.

Multiple cores allow for faster processing per second, which can increase the processing power and help a computer run faster.

Conclusion: IF you are using you PC for more intensive tasks then a 64-bit processor would be more beneficial for purposes like content creation and high-end gaming.

 

What are the threads?

Threads are virtual components or codes that divide the physical core of a CPU into virtual multiple cores. A single CPU can have up to 2 threads per core.

For ex: IF a CPU is a dual-core(i,e 2 cores) it will have 4 threads and if a CPU is octa-core (i.e 8 core) it will have 16 threads.
