Application Server : A Server

1)A network is when two or more computers are connected together and are able to share data and communication.

The mail server is like an computerized mail man that capable to delievers or handles e-mails across a internet or network. It can deliver e-mails from client computer to other mail servers or client computers. The client computer are the computer that you use to read or send mails across the networks. The example would be your computer at school or home. Furthermore, Smartphone or other mobile devices that have e-mail capbilities also can categorize as a client computers. The mail server uses Simple Mail Transfer Protocol(SMTP) for mail server to send email. SMTP is an application protocol that uses to store and forward emails. It will transfer your emails across the network and mail server will uses Post Office Protocol Version 3 (POP3) or Internet Message Access Protcol Version 4(IMAP) to receive the emails at the reciving ends.

Server Software: Web servers need to run software that manages access attempts to a website. When a user tries to access a website the web server software processes the access request and serves up the correct files that have been requested from the client’s machine. Examples include Windows IIS (internet information services) which runs on windows based web servers and Apache which runs on Linux based web servers. Server Software runs in the background and works over a network to allow a browser stored on a client machine to access the files that make up an eCommerce site.

A) As the machines are conected to an internet, we can expect hat Internet protocols manage

Paraphrasing (Stallings, 2007) the function of routers is to get the packet to a destination network. The router reads the header created by the Network Layer of the protocol stack on the source computer. The router can be configured to filter by protocol, source

Q. What is an operating system? A. Operating system works as an interpreter between computer Hardware and application. Operation system works as a user interface. Q. Types of Operating systems? A. There are two types of operating systems 1. SOS: Simple Operating System as for example- Windows 95,98, ME 2. NOS: Network Operating System as for example- Windows NT, 2000, 2003. Q. What is server? A. Server are computer that provides the services. As for Example:1. DNS Server 2. WINS Server 3. DHCP Server 4. RAS Server 5. VPN Server Q. What is RAS Server? A. RAS stands for Remote Access Server. It is basically use for mobile user in the network. This server provides the access connectivity for

Nevertheless, to begin with, a server looks the same as windows but has no special features such as, transparent background as servers don't need this as it would just use the memory of the computer. Also, every server can be assigned a role in which they contain many roles such as, DHCP, which is prompted when you install a server. However, it is also beneficial to know that one server can have many roles nevertheless; the more roles that you assign to one server would mean that it uses more resources so, it would be better to have more servers in order to share the roles.

Router is a device for networking that sends packets of data between the networks of a computer. The packet of data is forwarded to routers of the networks that contain the internetwork until the packet is at the destination node. A router can be linked to several data lines from various systems. The router reads the address information in the packet to establish the ultimate destination when the data packet is in any data lines (Liu, 2012).

A Wide Area Network ( WAN) is a computer network covering multiple distance areas, which may spread across the entire world. WANs often connect

Server: This is a computer that is designed to carry out specific functions at the request of other computers they’re connected to a network and direct the information stored on the network to clients, for example a web server will run software that receives requests from clients and then processes the request and delivers an output using HTML.

A computer and a server are usually two unique and separate devices and each are customized to handle specific functions and purposes. For example a web server will not need any type of display or monitor and can be located anywhere. But when it comes to a data server or client, there is typically a need for some form of display monitor so information can be reviewed and tracked. It is not uncommon in some occurrences that a device can function both as a computer and a server for the same application. This also can hold true for a application act as a client to other server for various other

Server: The server acts as the main computer. It had high end hardware just like the workstations, but

server responds to incoming client requests. It should be noted that a server typically starts

A Router is a Layer 3 or Network layer device that connects a network to another network. It connects networks with the same protocol such as RIP (Routing Information Protocol) and IP (Internet Protocol).

Mac OS X Server includes additional services, applications, and administration tools for managing and deploying servers. It's commonly found in small business, education, and large organizations.
