1.2 Internet Service Provider

As the name implies, Internet service provider, provide subscription with access to internet. The connection is accessible through multiple technologies such as wireless, dial-up and cable modem. At beginning of the internet era, the internet accessibility was only limited among universities and government research laboratory. ISP were established to spread the internet connection the home and employees on several section.

 The first ISP was established in 1990 at Brookline, Massachusetts. Typically, Inter service providers provides the ability to communicate with the internet through different services according to the customer needs. They also able to provide television services and other telephone services. ISPs provide different services according to the different pay rates which makes it popular for mass amount of households and small offices as well.

1.3 Web server

Web server is a system which returns files which are requested by the web browser. It utilizes HTTP to send the files through internet. Generally, every webserver consists of three main aspects as the physical server, server operating system and software which is used to facilitate the HTTP communication.  Simply, web server response to the client HTTP request and provide content or services. Every website must connected with a web server in order to reach to client side. In the current market, hundreds of web server is available and providing service.   Apache and Microsoft's IIS are the most popular web server which is used by thousands of website. Any server that delivers an XML document to another device can be a web server. A better definition might be that a web server is an Internet server that responds to HTTP requests to deliver content and services.                      

1.3.1 Apache web server

Apache is one of the most popular web server in current market. It is an open source server which support most of the operating system including FreeBSD, Windows, Linux, Uniz a mac OS X. More over 60% of the computer utilizes the Apache server. It is easy to solve administrative issues in the apache server comparing to the other platforms.         

1.3.2 IIS Web server

IIS is another popular server which provides most of same function as Apache. However, it is not an open source product hence adding personal modules is not easy (Karagiannis et al., 2015). It is a product of Microsoft and supports windows operating systems with optimal support.   

Introduction to Internet Service Provider (ISP)

2. Internet service provider           

              There are dozens of ISP available in Malaysia which provides several type of services according to the pay scale and contracts.

Explanation: The above network design is proposed for the Hasna Child Specialist Clinic, where all the connection are constructed with wires. The design is constructed in a way that all computer is capable of communicate with each other as well as the server. The arrows of the connection shows the data flow among the network devices. Only printer connections are connected one way.

3.1 Wireless Network Design

                                                         Wireless Network Design

Explanation: The above network design is proposed for the Hasna Child Specialist Clinic, where all the connection are constructed without any wires. The design is constructed in a way that all computer is capable of communicate with each other as well as the server. In order to provide the wireless connection access point can be used. The wireless approach can be beneficial as it can be less expensive and easy to manage as well.

4. Web Hosting Server 

Before selecting any web server, it is better to evaluate their functionality and advantages. There are hundreds of web server available in the market. Apache HTTP Web Server, Internet Information Services (IIS) and NGINX are the most popular web servers (Brügger, 2013). The advantages and disadvantages of the web servers are listed below:

4.1 Apache web server

Advantages:

• Apache HTTP Web Server is an open source platform which is available for free to anyone and n licence is required.
• One of the other advantages is multiple websites can be run from one server as it enables virtual hosts on the same server.
• Several websites all over the worlds provides numerous support and details. Hence, it is effortless to get assistant on any technical issues (Hosea et al., 2013).

Disadvantage

• Whenever constricting personalized protocol, it is frequently observe that some bugs are created.  The need of debuggers has been essential to manage the personalized protocol (Adelman& Chadwick, 2015).
• Apache provides the ability to modify the configuration which can arises heavy risk to security.
• In apache, disabling and recognising unwanted modules and services can also create serious threats while leaving them in cloud.

Advantages

• The main advantage of IIS is it provides various add-on which are free to use as well. Search engine optimization toolkit, database manager, web deploy and web platform installer are the most popular product available.
• The GUI assist the users to utilize the functionality very effectively and it also has good integration with performance monitor (Comer, 2018).
• IIS provides hundreds of premium feature as IPv6 Support, Network Isolation, 99% Uptime Guarantee, Unlimited 24/7 Support, Web-Based Control Panel, Full CGI Access and many more (Canali, Balzarotti& Francillon, 2013).

Disadvnatges

• IIS is a Microsoft product and support only windows OSs.  This is the main disadvantage as it cannot be used on other platforms.
• Development is not as open and quick as the open-source user-supported nature of Apache.
• It provides poor support as property of key cryptography that ensures a long-term key will not be compromised if a single component session key is compromised or broken.
