Knowing Understanding Web Server And How It Works

System Computer – Please understand the definition or understanding of the web server and how it works, which is also equipped with some examples. For the web master, maybe the term web serverr is not foreign anymore and maybe just people who often surf the internet is familiar with the term this one. But for those of you who have not fully understand or even not really know what a web server let us read the explanation in this brief discussion.

A. Explanation of Web Server

Web Server is a software that functions to receive HTTP or HTTPS requests originating from the client (web browser) and sends a response to the request to the client in the form of a web page. Or briefly the definition of Web Server is a server that provides services to the client which the client is asking for information that has to do with the web page.

In general the web serverr consists of two elements namely the computer and web serverr software used, so the computer can be used as a web server. Web Serverr can communicate with the client that is using HTTP protocol (Hypertext Transfer Protocol) and HTTPS (Hypertext Transfer Protocol Secure). With HTTP and HTTPS protocols, communication between server and client can be connected and can be understood easily.

B. Web Server Functions

As in the above explanation was that the web server function is to store and transfer documents or information requested by the client with HTTP or HTTPS protocol. Of course on a web there are various types of documents starting in the form of text, images, audio and video. Then the web server can also serve to send the filing within the page which may include images, text, audio or other file types. (Read also: Understanding HTTP notion and function briefly)

When will access the web page that exist on the server, usually we will type the web page in addres bar a web browser (chrome, mozilla, opera, safari, etc ..) then after the address is typed correctly then we will press enter or button Arrow in the address bar in the web browser so that the web page that we want can be accessed. So this is where the Web Server will work, the web serverr will find the data or files requested by the client. Once the client request file is found it will be sent and displayed on the web browser, but if the requested data is not found then the web serverr will send a specific message.

C. How Web Server Works

Actually quite simple way of working from web server that is accept request from client, after file or file found then web serverr send it back to client. As previously already explained that the intended client here is a web browser that can display web pages.

The web server has software / software contained on the server computer, and on the server computer the data of web pages and other files is stored. Same with the client computer, the server computer must also connect to a computer network such as a local network or the internet, so that the web serverr can be accessed by the internet.

If it describes how a web server works like: the client requests web data to the web serverr, then the command or request will be packed into a TCP form and then sent to the protocol address HTTP or HTTPS (HTTP and HTTPS are protocols used for WWW). The web data that the client requests will be searched for by the web serverr on the server computer. If the data is found it will be packed by the web serverr in the form of TCP, then sent to the client for the show. If the requested client data is not found then the web serverr will display the message to the client such as error, page not found or page not found, etc.

D. Sample Web Server

As for some examples of Web Server software that exist today, such as:

A. Apache HTTP Server

Apache is a web server that can run on various operating systems (Windows, Unix, Linux, etc.) whose function is to serve the website. The protocol used by apache is HTTP. Apache is supported by a number of GUI (Graphical User Interface) interfaces that allow easy management and handling of the server in case of errors. Because it is free and easy to use then apache is currently one of the web serverr that many in use by the web master.


XAMPP is a free software and supports a lot of operating system. Its function is as a server that can stand alone or in other words localhost. XAMPP consists of HTTP Server, MYSQL Database, and supports PHP programming languages ​​as well as Perl. XAMPP stands for X (and four operating systems) Apache, Mysql, PHP and Perl. XAMPP is a web server software that is quite easy to use for dynamic web.

C. Nginx

Nginx is a web server that is open source, just like Apache. The nginx web server (reads Engie x) is pretty easy to configure so it’s pretty easy to use, nginx installation is also quite easy, and supports many operating systems. In addition nginx is also famous for its stability, as well as the consumption of resources that are not too wasteful. Currently there are many who use nginx as a web serverr, especially web-web that has high traffic. (Read also: Knowing the meaning of the website and its kind)

D. Microsoft Internet Information Services / Microsoft IIS

That is an http web server that is used on windows sever operating system, starting from NT 4.0 server, Windows 2000 server, and Windows 2003 server. Microsoft Internet Information Service is one web serverr that is paid and widely used today. Microsoft Internet Information Services only supports microsoft operating system only.

Enough, that’s just an article that explains the understanding of the web server and some examples that we can provide. Hopefully this article can be useful and certainly can be understood also and apologize if there is a mistake.

Understanding Computer Systems And Component Complete

component Computer – A summary of the definition or understanding of the computer system and its components. Surely you’ve heard the term system, especially in organizations or other fields. Keep in mind that even computers have systems for executing commands and processing data. The system is interconnected with each other in order to produce information from the data it processed. On this occasion we will learn and understand together about the system on the computer, and here’s the explanation.

A. Explanation of Computer System

The definition of Computer Systems is a collection of computer devices that are interconnected and interact with each other to perform the processing of data, so as to produce information that is expected by the user. Devices contained in computer systems such as hardware, software and brainware.

These devices have their respective functions on a computer system. But when the operation of these computer devices will work and support each other. Hardware will not work without software and vice versa, and both will not be useful for generating information if no brainware is operating and giving orders. So it can be said that the computer is not as a tool but also a system.

B. Computer System Components

The following components are contained in a computer system, which include:

A. Hardware (Hardware)

Is a computer device that has a physical form, so this device can be in touch. For example such as motherboard, processor, hard drive, memory, power supply and others. Hardware itself is generally divided into 4 (four) parts, which include:

1. Input Device (Input Device)

Is a device on computer hardware that functions as a tool to enter data or commands on the computer. For example like Keyboard, mouse, web cam, scanner and others.

2. Output Device (Output Device)

Is a device on the computer whose function is to display the results of the processing of data. For example such as monitors, printers, projectors and others.

3. Processing Device (Device Pengeroses)

Is a device on computer hardware that functions as a data processing center. So it can be said this device is the brain of the computer and often also called the CPU (Central Processing Unit). Processing Device will communicate with the input, output and storage devices to execute the commands entered. Also read neighbor: Understanding Processor And How It Works More Completely.

4. Storage Device (Storage Device)

The CPU also comes with a data storage tool. There is a data storage device with a larger capacity as the main storage tool, which is usually called a hard drive. So we can store and delete data as we see fit. Along with the development of computer technology then the media storage device is growing very rapidly both in terms of capacity and shape. In computer storage device is generally divided into two parts, namely internal and external.

Internal storage such as hard disk, hard drive generally has a larger capacity because it is used as the main storage media on the computer, while for temporary storage media when doing process on the data is RAM (Random Access Memory). Then External Storage is the hardware to do writing, reading, and storage of data outside of the main storage media. For example external hard drive, DVD, flash and others.

B. Software (Software)

Software is also defined as software, so this device has no physical form such as hardware. Software can also be interpreted as a collection of electronic data stored and arranged by the computer, can be a program or connection to run various instructions instructions. So the software can not be touched and viewed physically, and it can be said also that the software is used to control the hardware. Software is divided into several kinds, such as:

1. Operating System (Operating System)

Computer Operating System is a basic program on a computer that generally works to connect users with hardware. It can also be said that the operating system is software that is responsible for controlling and managing hardware and operations performed on the system, including running applications that can perform data processing. Examples of computer operating systems such as Microsoft Windows, Linux, Mac OS, and others. Also read about: Understanding Computer Operating System And Type.

2. Application Program (Aplication Program)

The application program is a ready-to-use software. The application program is used to help the work of computer users in processing various data. On a computer software is often prepared according to the tastes and needs of its users. For example like Microsoft Excel, Microsoft Word, Microsoft Access, Photo Shop, Chrome, Mozilla and others.

3. Utility Program (Additional Program)

It is software whose function is to perform additional tasks, also known as support programs and functions. For example, such as programs provided by operating systems such as Data recovery, Disk Defragmenter, Sceensever, Backup, and others.

4. Programing Language (Programming Language)

Is a language that can be used computer users to communicate with computers, can also be said as a standard language instructions to communicate and give commands on the computer. Some examples of programming languages ​​such as PHP, Java, Python, C, Perl and others.

C. Brainware (Computer Users)

Brainware is the person who runs or operates the computer. Brainware is very important because computers can not be useful if not operated by humans. So brainware is everyone involved in computer utilization activities. Computer users are generally divided into 4 (four) kinds, which include:

1. Programmers

Is a person who has mastered many skills or one of the language pemograman, some languages ​​are often used programming such as PHP, Java, Phyton, C and others. So the programmer can also be said as the person who makes and tasked to prepare the program that is needed on the computer system that will be used to process the data.

2. Systems Analyst

It is the person who has the responsibility for research, planning, coordinating and recommending the choice of software, hardware and systems to suit the needs of its users (individuals, organizations and companies). An analyst system-also very important role in the process of developing a system. A systems analyst needs to have 4 (four) skills such as analysis, technical, managerial and how to communicate with others or interpersonal.

The ability to perform analysis can make it possible to understand organizational behavior as well as other functions, it can help in identifying the best possibilities for solving the problem at hand. Technical ability can make it possible to understand the various potentials and limitations of information technology. Managerial expertise can help in managing resources, projects and more. And Interpersonal skills can help in interacting especially with end users or users.

An analyst system must also be able to understand and work with different types of programming languages, operating systems, or hardware used by end users.

3. Administrator

It is a person whose job is to manage an operating system as well as some programs that are running on a computer system.

4. Operator

Is a person who utilizes existing computer systems or he only uses certain applications only to process data.

Thus explanation about the understanding of computer systems, if found some errors please forgive. Hope can be useful and thank you.

Fungsi Dan Pengertian Sistem Operasi Pada Perangkat Komputer

Apa itu Sistem Operasi?

Berita Komputer – Sistem operasi adalah komponen perangkat lunak inti komputer Anda. Ini melakukan banyak fungsi dan, dalam hal yang sangat mendasar, sebuah antarmuka antara komputer Anda dan dunia luar. Di bagian tentang perangkat keras, komputer digambarkan terdiri dari beberapa bagian komponen termasuk monitor, keyboard, mouse, dan bagian lainnya. Sistem operasi menyediakan antarmuka ke bagian ini dengan menggunakan apa yang disebut sebagai “driver”. Inilah sebabnya mengapa terkadang saat Anda menginstal printer baru atau perangkat keras lainnya, sistem Anda akan meminta Anda untuk menginstal lebih banyak perangkat lunak yang disebut driver.

Apa yang dilakukan pengemudi?

Driver adalah program khusus yang mengerti pengoperasian perangkat yang akan dijalin, seperti printer, kartu video, kartu suara atau drive CD ROM. Ini menerjemahkan perintah dari sistem operasi atau pengguna ke dalam perintah yang dipahami oleh komponen komputer yang dihubungkan dengannya. Ini juga menerjemahkan tanggapan dari komponen komponen komputer kembali ke respon yang bisa dipahami oleh sistem operasi, program aplikasi, atau pengguna. Diagram di bawah ini memberikan gambaran grafis dari antarmuka antara sistem operasi dan komponen komputer.

Fungsi Sistem Operasi Lainnya

Sistem operasi menyediakan beberapa fungsi lainnya termasuk:

– Alat sistem (program) yang digunakan untuk memantau kinerja komputer, masalah debug, atau mempertahankan bagian dari sistem.

– Satu set perpustakaan atau fungsi yang dapat digunakan program untuk melakukan tugas tertentu terutama yang berkaitan dengan antarmuka dengan komponen sistem komputer.

System operasi membuat fungsi interfacing ini bersamaan dengan fungsinya yang lain beroperasi dengan lancar dan fungsi ini sebagian besar transparan bagi pengguna.


Masalah Sistem Operasi

Seperti disebutkan sebelumnya, sebuah sistem operasi adalah program komputer. System operasi ditulis oleh programmer manusia yang membuat kesalahan. Oleh karena itu bisa terjadi kesalahan dalam kode walaupun mungkin ada beberapa pengujian sebelum produk dilepaskan. Beberapa perusahaan memiliki kontrol dan pengujian kualitas perangkat lunak yang lebih baik daripada yang lain sehingga Anda mungkin memperhatikan berbagai tingkat kualitas dari system operasi ke sistem operasi. Kesalahan dalam system operasi menyebabkan tiga jenis masalah utama:

– Sistem crash dan ketidakstabilan – Hal ini dapat terjadi karena bug perangkat lunak biasanya ada di sistem operasi, walaupun program komputer yang dijalankan pada system operasi dapat membuat sistem lebih tidak stabil atau bahkan dapat merusak sistem sendiri. Ini bervariasi tergantung dari jenis system operasi. Sistem crash adalah tindakan pembekuan sistem dan menjadi tidak responsif yang akan menyebabkan pengguna perlu melakukan reboot.

– Kelemahan keamanan – Beberapa kesalahan perangkat lunak membiarkan pintu terbuka agar sistem dapat dipecah menjadi oleh penyusup yang tidak berwenang. Karena kekurangan ini ditemukan, penyusup yang tidak sah dapat mencoba menggunakan ini untuk mendapatkan akses ilegal ke sistem Anda. Menambal kekurangan ini sering akan membantu menjaga keamanan sistem komputer Anda. Bagaimana hal ini dilakukan akan dijelaskan nanti.

– Terkadang kesalahan dalam sistem operasi akan menyebabkan komputer tidak bekerja dengan benar dengan beberapa perangkat periferal seperti printer.


Jenis Sistem Operasi

Ada banyak jenis sistem operasi. Yang paling umum adalah rangkaian system operasi Microsoft. Mereka termasuk dari yang terbaru sampai yang paling tua:

– Windows XP Professional Edition – Versi yang digunakan oleh banyak bisnis di workstation. Ini memiliki kemampuan untuk menjadi anggota sebuah corporate domain.

– Windows XP Home Edition – Versi biaya lebih rendah dari Windows XP yang hanya untuk penggunaan di rumah dan tidak boleh digunakan pada bisnis.

– Windows 2000 – Versi yang lebih baik dari system operasi Windows NT yang bekerja dengan baik di rumah dan sebagai workstation di bisnis. Ini mencakup teknologi yang memungkinkan perangkat keras terdeteksi secara otomatis dan perangkat tambahan lainnya melalui Windows NT.

– Windows ME – Versi yang telah diupgrade dari windows 98 namun secara historis telah terganggu dengan kesalahan pemrograman yang mungkin membuat frustrasi pengguna rumahan.

– Windows 98 – Ini diproduksi dalam dua versi utama. Versi Windows 98 yang pertama diganggu dengan kesalahan pemrograman namun Windows 98 Second Edition yang keluar kemudian jauh lebih baik dengan banyak kesalahan yang dipecahkan.

– Windows NT – Versi Windows yang dibuat khusus untuk bisnis yang menawarkan kontrol yang lebih baik terhadap kemampuan workstation untuk membantu administrator jaringan.

– Windows 95 – Versi pertama Windows setelah versi 3.x Windows yang lebih tua menawarkan antarmuka yang lebih baik dan fungsi perpustakaan yang lebih baik untuk program.


Ada jenis lain dari system operasi yang tidak dibuat oleh Microsoft. Masalah terbesar dengan system operasi ini terletak pada kenyataan bahwa tidak banyak program aplikasi yang ditulis untuk mereka. Namun jika Anda bisa mendapatkan jenis program aplikasi yang Anda cari, salah satu sistem yang tercantum di bawah ini mungkin merupakan pilihan yang baik.

– Unix – Sebuah sistem yang telah ada selama bertahun-tahun dan sangat stabil. Ini adalah yang pertama digunakan untuk menjadi server daripada workstation dan tidak boleh digunakan oleh siapa saja yang tidak mengerti sistemnya. Bisa sulit untuk belajar. Unix biasanya harus menjalankan komputer yang dibuat oleh perusahaan yang sama yang menghasilkan perangkat lunak.

– Linux – Linux mirip dengan Unix yang beroperasi tapi gratis. Ini juga tidak boleh digunakan oleh siapa saja yang tidak mengerti sistem dan bisa sulit untuk belajar.

– Apple MacIntosh – Versi terbaru berbasis Unix namun memiliki antarmuka grafis yang bagus sehingga keduanya stabil (tidak sering macet atau memiliki banyak masalah perangkat lunak seperti sistem lainnya) dan mudah dipelajari. Salah satu kelemahan sistem ini adalah hanya bisa dijalankan pada perangkat keras buatan Apple.

History of microsoft windows and understanding microsoft windows

Computer news – Windows History And Understanding Windows-Who does not know Window operating system, of course you are working using a computer or laptop is no stranger to the name of Window.

Understanding of window itself as quoted from wikipedia is an operating system developed by Microsoft by using a graphical user interface.

If we look at the history of Window development, the Window operating system has evolved from MS-Dos to an operating system based on text mode and command-line.

The first version of Window was Window Graphic Environment 1.0 first introduced on November 10, 1983, but only came out in November 1985. This version was made to meet the needs of the computer with a pictorial display. Window 1.0 is an additional 16-bit software (not an operating system) running on MS-DOS (and some variants of MS-DOS), so Window 1.0 can not run without a DOS operating system. Versions 2.x and 3.x are also the same.

Some of the last versions of Window (starting with version 4.0 and Window NT 3.1). This version is a stand-alone operating system that no longer relies on the MS-DOS operating system.

With the development of Window operating system, Microsoft can develop Window and control the market to reach 90%.

History of window in full can you see below:

4. Windows 3.0 (1990)

History of the next development of Window 3.0 which provides enhanced capabilities and graphics 16 colors, and do not forget the support of intel 386 processors. This version is popular, and growing rapidly when the release of Window Software Development Kit (SDK). This helps developers to focus on writing applications so they can ignore the writing of drivers.

5. Windows NT 3.1 (1992)

In early 1992 Window 3.0 began to be developed again into Window 3.1. Window development is not in vain, because it sold 1 million copies in the first two months. Recorded at least approximately 25 million users of Window 3.1 legal in 1993.

6. Windows for Workgroups 3.11 (1993)

Window 3.11 adds a network between multiple computers or is called peer-to-peer. It also has network support on a domain.

7. Windows NT Workstation 3.5 (1994)

Window NT Workstation provides the ultimate protection for business users and data applications. With the support of OpenGL graphics standards, this operating system can provide advancements for application development in the form of software, industry, research, and business products. Window NT Workstation 3.5 has reliability on 32-bit productivity and has the ability to accommodate file names up to 256 letters.

8. Windows 95 (1995)

Windows 95 was released on August 24, 1995. The Operating System is based on a 32 bit system that supports multi tasking, advanced file systems, threading, networking, etc. Version 95 also includes a thorough review of the interfaces.

9. Windows NT Workstation 4.0 (1996)

There is an Upgrade aimed at this business-class desktop operating system which will provide simpler usage and simpler settings, greater network output, as a tool for intranet development and management. Window NT Workstation 4.0 also includes a Window 95 look with enhanced access to internet and intranet.

10. Windows 98 (1998)

Windows 98 operating system is an improvement of the Window 95 operating system. This operating system has the advantage that there is a renewal in the hardware drivers and has been supported FAT32 file system better.

11. Windows 98 Second Edition (1999)

As the name suggests, Window 98 SE has been updated on several important things in Window 98. In addition, Window 98 offers several types of hardware compatibility as well as internet offerings.

12. Windows Millennium Edition (Windows Me) (2000)
Next is the development of Window that offers for home PC users, then Window ME already provides music, video, and home network

Users can also repair their system with system restore.

13. Windows 2000 Professional (2000)

Windows is a Window that is just an update. Window is also designed to replace Window 95, Windows 98 and Window NT Workstation 4.0 on all business desktops and laptops. Built from the basic code of Window NT 4.0, Window 2000 is already experiencing rapid development on reliability and ease, as well as mobile computing support.

14. Windows 2000 Server

Windows 2000 Server is a Network Operating System (NOS) that can configure and manage small, medium, or large networks.

Windows 2000 Server is a continuation of Window NT Server 4.0 technology where there are various new facilities. Window 2000 consists of 3 types namely the standard version (Server), Advance Server, and Data Center Server.

15. Windows XP (2001)

The history of Window XP started in 2001. There is an innovation in the experience that Microsoft provides for PC users. With Window XP, home users can enjoy various music, video, messaging and photo formats on their own computers. Business users can also work faster and smarter, and do not forget the fresh look.

16. Windows 2003 Server (2004)

Windows 2003 server is still classified as a new product from microsoft where in using the operating system, the minimum need we must know first because if there is a mismatch it can affect the performance of the server itself.

17. Windows Fundamentals

The history of Window XP still continues with the release of Windows XP Service Pack 2 in July 2006 by Microsoft. The Window operating system is aimed at the thin-client market, referred to as Window Fundamentals for Legacy PCs (WinFLP). WinFLP is only available to Microsoft Software Assurance customers. The purpose of WinFLP is to provide an upgrade option to its customers who still use Window 95, Window 98, Window Me and Window NT Workstation.

18. Windows Vista (2006)

History of Window Vista began in 2006. The success of Window XP makes Microsoft does not just stop but continue to develop the next Window operating system. This version is called Window Vista. For businesses Window Vista was released on November 30, 2006 while for home users was released on January 30, 2007.

Window Vista is recommended because it has a more robust security level in the presence of a limited user mode, called User Account Control (UAC), which replaces the “administrator-by-default” philosophy that exists in Window XP.

Window Vista is famous for more “catchy” graphics features, or called Window Aero GUI. Window Vista also provides a more secure version of Microsoft Internet Explorer, and support for the new version of Window Media Player or version 11.

Is it Possible to Run a Computer Without RAM?

Computer news – Discussions about computers are never endless to talk about. But, have you ever wondered whether it might be running a computer without RAM? Just imagine, what kind of computer running without RAMM huh?

For that, Jaka want to discuss about it. To make it clearer whether the computer or laptop can run without RAM. Approximately, guess what?

Is it Possible to Run a Computer Without RAM?

If you ever put it, it means getting caught if you do not understand what the computer looks like. Because, detik computers that embed a processor like Intel, can not run without using RAMM. RAMM is the place where the CPU can tell it to read and write data.

If you’ve ever asked about it, it’s like asking if a car can run without a tire. Even if it can, it means it’s an experimental car, not an ordinary car. And this also applies to computer brader.

What Makes It If Indeed Computer Can Walk Without RAM?

If we suppose, if the computer is true to run without RAM, it is guaranteed it will be the most slow computer in the world that exists today. So, you will not be able to ath one bit.

In the past, there was a so-called Drum Computer like the IBM 650, it used magnetic drums as working memory (not RAM) can still run. But, its performance is very sad compared to today’s computers.

That he explains whether the computer can run without RAMM or not. Make sure you also read related Computer or other interesting articles from Jofinno Herian.
