Database is a collection of data items are related to each other which is organized under a particular scheme or structure, stored in the computer hardware and software to manipulate for specific purposes. Database is required because:
* One important component in information systems, because it is the basis of providing information
* Determine the quality of information: accurate, timely and relevant. Information can be said is worth more effective if its benefits compared to cost to get it.
* Reduce duplication of data (data redudancy)
* The relationship data can be improved (data relatability)
* Reduce waste storage places outside

Show romanizationOperating system (usually abbreviated to the OS, O / S or kernel) is an interface between hardware and software in computer systems. OS is responsible for managing and coordinating activities and sharing of limited resources of the computer. Operating system that acts as host for applications that run on the computer. As the host, the main purpose of the operating system is to handle the details of hardware operation. This frees the application program to manage low-level hardware and makes it easier to write software. Almost all computers, including laptops, desktop computers, supercomputer, and even video game consoles, using the operating system from various types. Some older models may use an embedded operating system, which may be stored on compact disk or data storage device.
The operating system offers a number of services for system programs, user interface, application programs and hardware. Applications access these services through system calls and device drivers from Hardware. Through the system call, the application can request service from the operating system, pass parameters, and receive the results of operations. Users can also interact with the operating system using some type of software or hardware that offers a user interface (UI), such as keyboards, typing commands to the command line interface (CLI) or using the keyboard and mouse with a graphical user interface (GUI, commonly pronounced " Gooey ").
Contemporary operating systems are widely used as Mac OS, Windows, Linux, BSD and Solaris. Although the servers are running Unix or its derivatives, embedded devices that separate the market between several operating systems.

If you want to make some network computer hardware or hardware that need to be prepared. In general to create a computer network, required the following equipment:
* At least there is one computer that acts as a server (data center)
* There is a computer workstation (work)
* The operating system support such as Windows NT networking, Netware, Linux, etc.
* Peripheral tissue such as the Network Interface Card (NIC), hubs, etc.
* Media liaison between computers such as cables, connectors, terminators, etc.
Glance again we need to understand what e-Learning is. E-Learning is a distance learning (distance learning) that take advantage of computer technology, computer networks and / or the Internet. E-Learning allows learners to learn through computers in their own without having to physically go to follow the lessons / lectures in the classroom. E-Learning is often also understood as a form of web-based learning that can be accessed from the intranet on a local network or the Internet. Actually, the e-Learning materials should not be distributed as on-line either through a local network or the Internet, the distribution of off-line using the media CD / DVD also includes the pattern of e-Learning. In this case the application and learning materials developed and distributed as needed through the media CD / DVD, then the learner can take advantage of the CD / DVD and learn at the place where he is.

Literally, the Internet (short than words 'interconnected-networking') is a series of computers connected in a series. When the Internet (the letter 'I' large) is a public computer system, a globally connected and uses TCP / IP as the packet exchange protocol (packet-switching communication protocol). The largest internet series called the Internet. How to connect the circuit with Siwak F is called internetworking.
Central circuit that forms the Internet beginning in 1969 as the ARPANET, which was built by ARPA (United States Department of Defense Advanced Research Projects Agency). Some initial investigations donated by ARPANET including Siwak F-series without center (decentralised network), queuing theory, and packet exchange Siwak F (packet switching).
On January 1, 1983, the ARPANET protocol circuit switched its center, from NCP to TCP / IP. This is the beginning of the Internet as we know it today.
In about the 1990s, the Internet has evolved and most users connect computer networks that exist.
Internet guarded by treaties or multilateral bi-and technical specifications (which describe the protocol of the transfer of data between circuits). These protocols established under discussion Internet Engineering Task Force (IETF), which is open to the public. The agency issued a document known as RFC (Request for Comments). Some of the RFC used Internet Standard (Internet Standard), by the Internet Architecture Board (Internet Architecture Board - IAB). Internet protocols are commonly used such as, IP, TCP, UDP, DNS, PPP, SLIP, ICMP, POP3, IMAP, SMTP, HTTP, HTTPS, SSH, Telnet, FTP, LDAP, and SSL.

Portable devices are always connected to the Internet will be consumed as many as 10 million people around the world this year 2010, according to industry observers predicted the result, Deloitte. NetTabs, known as a touchscreen tablet, designed for web surfing, has shape larger than a smartphone, but smaller than a laptop, will become the new consumption in 2010, continued the company Deloitte.
Gadget that will reap huge profits is a smartphone, Deloitte claims, because the smartphone offers a bigger screen for web surfing and watching videos. However, unlike the netbook and notebook, which both offer larger display than a smartphone, NetTabs much lighter and cheaper.
While the wireless connection will be popular for NetTabs, supported by network providers, but consumers seem to prefer the subsidy from the carrier, because NetTabs will dibandrol cheaper prices than most smartphones, Deloitte added. NetTabs even expected to threaten the existence of market e-book reader, where Deloitte predicts that sales of e-book reader will reach 5 million units globally, the end of the year.
Deloitte also predicts the existence of the development of a broader technology, which is based conversations with more than 7000 technology, media and telecom expert who will create the gadgets of technology also during 2010.

In Corel Draw 13 you can give special effects to the image or text by using the menu to give effect to the object. To use the command bitmaps are also some things to note include:
* Object images or text must be converted into a type of bitmap.
* Securities bitmap that you can only use the bitmap image.
* Each bitmap effects are processed in RAM memory.
* Application of bitmap effects on the large image will take a long time in processing.
Penggunaan Efek Bitmap" onmouseover="this.style.backgroundColor='#ebeff9'" onmouseout="this.style.backgroundColor='#fff'">-> Use Bitmap Effects
Giving effect to Bitmap Images
Some show a preview bitmap effect before the effect is applied.
Below are the steps to give effect to a bitmap image object:
1. Import" onmouseover="this.style.backgroundColor='#ebeff9'" onmouseout="this.style.backgroundColor='#fff'">Import the object image with the File menu> Import
2. Click the menu bitmaps and select one type of effect from the displayed submenu. For example: Radial Blur dialog box that appears Radial Blur.
3. Click the Expand button to display the preview window and press the button to display the Multiple Page 2 preview display.
Picture Description
Left window is the object of the original image and the right window is the result of bitmap effects.
4. Specify a value or option to adjust the effects resulting from the bitmap effect. For example, the content value of 26.
You can shrink or enlarge an existing object display in the left pane (Object Original)
You can also specify the particular object that is not obscured by clicking the plus button and then click the object that will not be obscured in the left pane (Object Original).
5. Press the Preview button to see the results of a bitmap effect to the entire image. Click the OK button and watch the results.
