Example – Apache – known for playing a key role in the growth of the world wide web it is the most popular web server, it serves more than 100 million websites. This allows people to be able to see one or more of the websites held on the server.
IIS stands for internet information services it is a web server created by Microsoft it supports HTTP, HTTP, SFTP, FTPS, SMTP, NNTP. It listens for requests and returns the specific web page to the user.
Email servers
Definition – An email server is computer within a network that works as a virtual post office it consists of a storage area where the email is stored for local users, a set of user definable rules which determines how the server will react to the destination of the message, a database of user accounts so that the mail goes to the write inbox.

Layer 1 of TCP/IP is network access, this layer includes wires, network interface cards, etc also other related details in this layer are connectors, signal strength and wavelength, it uses the required LAN operating algorithms. It is also responsible for placing the data within a frame, the frame is the package that holds the data.
HTTP - stands for hypertext transfer protocol, this is an application protocol for disturbed, collaborative and hypermedia information systems. It is the foundation of data communication for the web. It is the protocol to exchange/transfer hypertext which is structured text that uses logical links between nodes.
Email security services will include blocking ransomware and emerging threats with the highest effectiveness and accuracy, stopping new and sophisticated threats such as ransomware, spear phishing, and business email compromise. Spear phishing will be prevented by having a comprehensive defense that includes multiple layers of protection, strong isolation , deep visibility and dynamic security awareness. Attacks will be contained and responses will be orchestrated across endpoint security and web gateways by remediating attacks and blacklisting threats. Dynamically classify impostor email and other threats that don't involve malware. Sender-recipient relationship, domain reputation, email headers, envelope attributes and email content will be analyzed. Custom rules will be integrated allowing group and user level controls to meet the needs of the client. Quarantines will enable the customer to separate email
The World Wide Web and the internet is not the same thing, and they are often confused with being the one and same. However, the internet existed long before the www (World Wide Web). The internet refers to the massive network of computers stretching all over the world. The word internet also found its origin through this, the word comes from the two words interconnected and network. Though we can all with each other through internet, all the computers are not connected to the one and same mega computer. For each network there are one or several computers that hold the information that is needed to access all the information. This arrangement is known as the client-server architecture.
Mail in the work environment often offers administrative services, and ways we can highlight the different services are by seeing them as either internal or external services. Incoming mail (mail coming to the company), is often dealt with at 4Social Work (a smaller organisation) by the administrators, rather than a large postal room in larger organisations. Internal mail is slightly different as it still is still addressed to the company, however it is mail from one worker to another, who may be in different locations (different region or country). For instance, a pay slip or p60. Incoming mail will include: courier companies and the post office delivering mail, faxes and hand delivered mail. Outgoing mail can either be internal or external.
Among all the communication mediums used in an organization, emails are used widely as an effective form of a business communication. From the company’s CEO to an employee of the business, emails are very easy and inexpensive. “Internal emails can function as an effective communication for sharing basic information, such as new cafeteria prices, paper use guidelines, or security precautions, for example. Sending simple messages to an entire workforce with just the click of a mouse is fast, easy, convenient and can save the company money”. (Lorette,
The World Wide Web started as an idea that focused around the government’s need to communicate if there was a real war. In 1964 the Cold War was at its peak, the Advanced Researched Projects Agency, or ARPA began researching and developing a way to get computers to “communicate with each other,” this is how it all started (The Internet's History and Development). The government scientists who were, “developing networking technology in the 1960's knew that what they were building would be far bigger than themselves; nobody, however, could have predicted the explosion in Internet access and interest in the past several years” (The Internet’s History and Development).
In main interface aspect, OTRS support for MIMEhttp://tools.ietf.org/html/rfc2046 emails with attachments. In order to increase security for sensitive content and improve searching speed, OTRS converts HTML into plain text messages automatically. When system receives a mail, mail will be filtered and preprocessed by pre-defined rights. For example, email contains ticket number will directly link to specified ticket. PGP and S/MIME standards are accepted to key/certificate management and email processing. Ticket could be responded based on pre-defined queue templates. Agents receive notification when ticket created, updated and whenever state change happened which improved follow-up of the ticket. In addition, agent could define customized follow-ups rule based on call, ticket or request. Ticket number is generated by system. Generation rule is modifiable.

The Internet is a global network connecting millions of personal, institutional and company computers. The number of computers used by the internet is growing rapidly. The United States is connected with over 100 countries worldwide and linked together to exchange of data, news and opinions. The Internet is decentralized design. This means that there isn't just one computer that stores all of the information from the Internet. There are many independent host servers located throughout the US and the world that store the information made available to the global Internet community.
Electronic Mail, a means of communication that is growing at a very rapid rate. In this paper, I will write about introduction of e-mail, the advantage and disadvantage of e-mail, mailing lists, sending an e-mail message, sending attachments, e-mail improvement, and security features. Introduction of Electronic Mail Electronic mail (E-mail) has become popular and easy way of communication in this decade. E-mail is a method of sending and receiving document or message from one person to another. E-mail is not only replacement for postal mail and telephones, and also it is a new medium. E-mail send plain text, images, audio, spreadsheets, computer programs can attach to an e-mail message. Using the e-mail, you must have a computer on a network. The computer must require a modem and phone line. Sending and receiving e-mail needs an e-mail program. Every e-mail user requires an e-mail address. This e-mail address is similar to a postal address. E-mail address is written as username@domain, for instance, PCLEE@juno.com. The username is used for sending and receiving e-mail.
Electronic mail (e-mail) - Electronic mail. Permits you to send and receive mail. Provides access to discussion groups, often called Listservs®, after the software they operate under. Telnet or remote login. Permits your computer to log onto another computer and use it as if you were there.
Email (electronic mail) was one of the biggest breakthroughs in communication when the internet was commercialized. With email, it became possible to send messages and letters across the world in a matter of seconds to the recipients address. Email was used as an alternative to conventional mail or snail' mail, as the term was introduced to describe its speed. As technology improved, it became possible to attach' documents, photographs and even sound clips or songs to emails which made mail by post redundant. Emails used packet switching software whereby the email was broken down into packets' and sent via the internet to the recipient.

Have you ever wondered who invented the World Wide Web? The answer is quite simple. The history of the World Wide Web, what a URL is what it contains along with what a web page contains are all important information when one is wanting to learn about the World Wide Web. We all know that the Internet is a source of all sorts of information. It’s like having a huge dictionary at your fingertips. In this day and age people are using the web for school, work, games, reading, weather, investments (Shelly and Vermaat). There are so many different things people can do with the web. The options are endless.The World Wide Web was invented in 1989 by Tim Berner-Lee. Tim Berner-Lee was working at a research facility,(CERN), as a software engineer. CERN had software engineers performing many experiments. When they were finished they would return to the regular place of business and would have no way of contacting one another. At this time Tim Berner-Lee understood the idea of connecting all computers together, and this was the beginning of the Internet (Peter).
