Server - The important piece of computers

Data Center Interior

In todays life, computers are becoming so basic needs for human. Even every house has a computer actually not house only every person has PC or laptop of their own. So it is necessary to know about computers and network. As we all use internet which use network to work. Servers is also a part of it, a very important part. A basically a server is a piece of computer which provides data to other computers. There is many types of server like web servers, mail servers, etc. Basically the user of the server are known as client. The role of server is to share data as well as resources and distribute work. Hardware requirements for servers depends on the it's purpose and software.

Server Clusters

The server clusters is also known as server farm. It is a collection of computer server. Server farm consist of lots of computers which requires lots of energy and cooling system. It also has backup server for the case of primary servers failure. It uses high speed processors connected by either Gigabit Ethernet or by Infiniband or Myrinet.

Operating System

The common and most use operating system for server are Unix like. It has GUI available or optional. Reconfiguration and update of hardware or software can be done by it without restarting. It has flexible and advanced network capabilities. Automation capabilities such as daemon in Unix and services in windows. It has tight system security. Advanced detection ability.

RPA - UiPath

What is RPA? RPA (Robotic Process Automation) is technology which let organization to make their task easy by allowing them to automate the task just like a human being was doing them across application and systems. The purpose of RPA is to transfer the process execution from humans to bots. Robotic process automation interacts with the existing IT architecture with no complex system integration required. UiPath - The vendor UiPath is a New York City-based global software company that develops a platform for robotic process automation (RPA). The company's software monitors user activity to automate repetitive front and back office tasks, including those performed using other business software such as customer relationship management or enterprise resource planning (ERP) software. UiPath develops software to automate repetitive digital tasks normally performed by people. The technology combines emulating how humans read computer screens (AI Computer Vision) with APIs, and give

Some Pseudoscience and myths we still believe

Hi frnd, In this post I have mentioned some science fact and myth, among which some myth are not properly proof by science yet. But we still used to believe in that. That are also known as Pseudoscience. Bad Small Can Make You Sick According to the once-popular miasma theory, diseases were caused by "bad air." Miasma is the name for this foul-smelling, poisonous vapor that carried particles of decaying matter. In 1854, epidemiologists traced a deadly outbreak of cholera to water contamination. Discovering no organic matter in the water that was undoubtedly causing all the cholera, John Snow debunked miasma theory by proving that cholera is a waterborne disease. Soon, germ theory caught on and miasma flew out the window. Diffrent Parts of Tongue Have Different Taste Maybe this is one you learned in school, and maybe even still believe. Sorry, the idea that the tip of your tongue picks up sour tastes, or the middle of your tongue processes sweetness, or whatever, i

Alien could be discovered on this new class of 'Hycean' exoplanet.

In the discovery for Alien life, astronomers have mostly looked for planets of a similar size, mass, temperature, and atmospheric composition to Earth. Recently, the team of astronomers find a class of planets that may prove the existence of Alien Life. Such exoplanets are more numerous in planetary surveys than rocky ones, which means they could be fertile territory in the search for alien life. The researchers have dubbed them 'Hycean' worlds. In the new study, researchers identify one such class of alien worlds "Hycean" planets, which are up to 2.5 times larger than Earth and feature huge oceans of liquid water beneath hydrogen-rich atmospheres. Hycean planets appear to be incredibly abundant throughout the Milky Way galaxy, and they could host microbial life similar to the "extremophiles" that thrive in some of Earth's harshest environments, study team members said. "Hycean planets open a whole new avenue in our search for life elsewhere,"
