Without virtual testing of circuit, of Microprocessor in the Display - we can't Analyze, the internal circuit design of Microprocessor. Because internal circuit design of Microprocessor are so sophisticated or complex, of which can not be Modified again soon after to be generate.

A DNS(Domain name system) server translates a domain name(As if facebook.com) into a numerical IP address that is used to path communications between nodes. DNS (acts like a translator), understands to only IP address- By IP we can open anyone website. But the IP address of all website can not remember, hence have created to DNS. To increase performance, DNS saves to (Modified data or translated data) in the system for a certain amount of time. Of which, is called Cache. Until that cache doesn't expire in the system, till then website will open by using that cache.

Cloud computing is dispensation of computer services - in the cloud computing system is included servers, (data storage), networking as well as analytics and the intelligence plus computing power. In simple - we can access to data one location to another location (virtually). Cloud computing is on- demand subservience computer system resources, especially, it is used for data storage(cloud storage).

After to be start to computer, first of all -what screen looks that is called BIOS(Basic input output system). Added with these motherboard, is a firmware or software- what helps to computer in to(operate or start). Without this - computer can not run, anytime. In the computer, in the memory - during loading to operating system, then BIOS runs to POST(Power on self test)system hence that every part of hardware or software are working, correctly, yes or no. This is because of [(to be start of POST(Power on self test)]. After this, our computer runs any program.

For (VFX and Graphics motion designing as well as 3D (Modelling, Rendering and Animation) are best considered to NVIDIA graphics card whether are GTX or RTX than other company (AMD or Intel). Because in the NVIDIA graphics card are included high quality GPU.

In the system, UEFI(Unified extensible firmware interface) is developed for(simple file and secure pre boot environment) that before by the arrival of virus in our system- prevents injection of dangerous code (Malicious code). It can access to all memory and supports ( 32 or 64 bit Processor plus GPT(Guide partition table)).

Router is Networking device. It can check both address(MAC plus IP). It works with three layers (Physical + Data link + Network). While switch works with two layers (Physical plus Data link).
