Computer technology is widely used all over the world, in fact, without server machines, there is no existence of world-wide-web (www), online shopping, banking experience, and all other server-dependent tasks. How do servers work is a simpler concept and anyone can easily understand the functionality, major components, and realizes other related concepts, like Big Data and cloud computing. I am going to briefly explain all these concepts in this article.
What is a Server Machine?
Unlike personal computers, it is a powerful type of computer that mostly used without screens, keyboards and store all the data associated with the websites hosted on it. A server is responsible to store the website files and share them with other computers. It is commonly used to accept requests for web documents and responses with particular information to the clients. Laptop or personal computers are used to solve mathematical problems and designed to communicate with people.
How Do Servers Work?
When you enter the URL of any website, there are many servers involved to provide you requested data and information of the particular website. Initially, your web browser breaks down the URL into three parts:
Hypertext transfer protocol (HTTP or HTTPS) is a communication channel or language that is used by the servers and browsers to speak to each other.
The domain name server (DNS) translates the domain (or website) name into a numerical IP (internet protocol) address of the server having the files of the requested website.
It is related to the files including images, HTML, CSS, fonts, and many more related to that particular website.
The process starts with the web browser request of a particular web page searching for the right IP address associated with the requested domain. The IP address is assigned by the ISP (Internet Service Provider) and changes when you reconnect to the internet but web servers have the same IP addresses all the time and these IP addresses are used to access the website data. When this information is received by the web server, it will find and collect all the information needed to display the site including dynamic elements. The web server sends back this website data in the form of a response to the web browser and a complete page is displayed to the user.
What are the Major Components of a Server?
Server computers have many components for executing code, sending or receiving network data, and storing the data for a short-term and long-term basis. Keep in mind, these components are very powerful than laptops or mobiles but they play the same role.
The processor is the brain of servers and able to solve the billions of calculations withing a second and execute the code. In this modern era, powerful processors have multiple cores that allow them to execute more instructions at the same time and powerful computers have multiple processors having dozens of cores to enhance their workability. Temok dedicated servers are equipped with powerful Intel Xeon processors having multiple cores to provide exceptional speed and quality of computing operations. Moreover, the dedicated servers contain the fastest storage (SSDs) for long-term data storage, DDR3 RAMs, and more cache memory for carrying out the instructions executing now and in the near future.
Random Access Memory (RAM) is the short-term memory used to store the data that is currently working with Operating System or software application by the processors. Modern processors need this memory that is used to read and write data faster than hard-drives. Every Server will take more time if the data should be retrieved from the hard-drives every time.
Servers have to store all the website data, libraries, operating systems, application codes, different files, and databases. Usually, traditional spinning hard drives and solid-states-drives are used to store the data on the server-side. SSD drive is expensive and faster than other hard disk drives. The selection of storage is based on needs and requirements. For example, a file archive server doesn’t need to be very fast but the database server needs to write and read data quickly.
Keep in mind, if a single storage device is connected with the server and eventually stops the working then all websites hosted by the server will be down that is not acceptable for better online user experience. Most of the servers have a Redundant Array of Independent Disks (RAID) to increase fault tolerance. People can also protect their website data and take the full backup of the website to protect the confidential data.
How do servers work? Server working becomes possible when they connected to the internet that is a combination of networks. If anyone needs to get reliable and higher speed his server must be equipped with higher bandwidth. If a website is hosted on a server having smaller bandwidth, the website users cannot access the website after a certain point, so the company will lose potential customers. It is recommended to use a higher amount of bandwidth in order to get optimum results.
Nowadays, servers are available in a wide range of specifications for fulfilling any type of client requirements. Every business has particular requirements according to the business goals and a number of visitors, so understand your requirements and choose a perfect server. Owners can focus on their marketing strategies instead of managing the servers because Temok will manage your servers more efficiently and keep them active.
