Email is a very popular way of communicating with others over the Internet. An application that allows users to send, receive, and read email is called an  email client . Red Hat Enterprise Linux includes several email applications, including graphical email clients like  Evolution  and  Thunderbird , and text-based clients like  mutt . Each of the email client applications is designed to suit specific types of users; so, you can choose one with the features that best suits your particular needs. The purpose of this chapter is to demonstrate how to use some of the popular email applications included in Red Hat Enterprise Linux. Since all email clients perform the same basic tasks (send and receive email), you should choose one that is convenient and easy to use. This chapter briefly discusses the following email clients: Evolution Thunderbird Mutt , a text-based email client Before you launch an email client, you need information from your I...

Internet Applications Hey let's write some apps that use the Internet! Those Layers Again So what's an app, or application? Generally, it's something that does something for people, without any concern for how data is actually run between the hosts. In the traditional 5-layer view, anything above TCP is considered  application-level  communication Application Transport (e.g. TCP, UDP) Internet (e.g. IP) Network Interface (e.g. ARP) Physical Transport software just routes packets between applications; it doesn't care what the application data is. Examples of Applications Here are some distributed applications that require well-defined application level protocols Sending and receiving email Browsing information archives Copying files between computers Playing interactive games Most applications not only shield users from transport details, they shield users from protocol "numbers." They define symbolic names for resources and service...

Difference between internet intranet and extranet Internet Intranet Extranet It is a  Global system  of interconnected computer network. It is a  Private network specific to an organisation. It is a  Private network  that uses public network to share information with suppliers and vendors. Not regulated by any authority. It is regulated by an organization. It is regulated by multiple organization. Thus content in the network is  accessible to everyone  connected. Thus content in the network is accessible only to members  of organization. The content in the network is accessible to members of organization &  external members with access to network. It is largest in terms of number of connected devices. It is small network with minimal number of connected devices. The number of devices connected is comparable with Intranet. It is owned by no one. It is owned by single organization. It is owned by...

Stanford scientist Manu Prakash makes water based computer Jun 9, 2015, 06.31 PM IST 25 comments 62 in Share Share More A A READ MORE  Stanford University | Scientist | Manu Prakash Manu Prakash, who amazed the world last year by building a paper microscope, has now come up with a computer that works by moving water droplets. Prakash is an assistant professor of bioengineering at Stanford University and he has developed the water computer with the help of two of his students. He was born in Meerut, India. What Prakash did was devise a system in which tiny water droplets are trapped in a magnetic field. When the field is rotated or flipped, the droplets move in precise direction and distance. This became the basis of the computer clock, which is an essential component of any computer. Computer clocks are responsible for nearly every modern convenience. Smartphones, DVRs, airplanes, internet - without ...
