Digital television or DTV is a kind of television that uses digital modulation and compression to broadcast video signal, voice, and data to the television. Digital television is a tool used to capture digital TV broadcasting, the development of analog to digital broadcast system that converts the information into digital signal form of bits of data

Digital TV Frequency
Technically, the tape of the radio frequency spectrum used for analogue television can be used for digital television broadcasting. Comparison of bandwidth used analog technology to digital technology is one: 6. So, when analog technology requires 8 MHz bandwidth for a single transmission channel, digital technology with the same bandwidth (using the technique of multiplex) can emit as much as six to eight channels transmitting simultaneously to different programs.

Digital TV transmitter systems
There are three standard digital television transmitter systems in the world, the digital television (DTV) in the United States, terrestrial digital video broadcasting (DVB-T) in Europe, and integrated service digital broadcasting terrestrial (ISDB-T) in Japan. All standards-based digital system transmitter system coding OFDM system with MPEG-2 sound code for the ISDB-T and DTV as well as MPEG-1 for DVB-T.

The advantages of digital TV frequencies
Broadcast using a digital system to have robustness against disturbances and easy way to repair digital codes via error correcting codes. The result is picture quality and sound are far more accurate and higher resolution than analog television broadcasts. In addition to digital television broadcasts using low power.

Graphic tablet

Graphics tablet is a hardware or computer input device that allows the wearer to draw by hand and insert a picture or sketch directly into the computer, like drawing on paper using pencil.

Operation

Passive Tablets
Passive tablet, which was introduced by Wacom, using electromagnetic induction technology, where the horizontal and vertical wires of the tablet operating as a sender and receiver rolls (coils). Tablet generate electromagnetic signals, received by the LC circuit in the pen. Cable in the tablet then change the mode of receiving and reading the signals raised by the pen.

Active Tablet
The difference lies in the passive tablet stylus. Active stylus on the tablet strength depends on the internal battery, not on tablets. This pen to create his own energy (self-powered) to then generate a signal on the tablet. By removing the obligation to supply energy to the pen, it means that the tablet will be able to obtain a constant signal to the pen, because he did not have to replace the signal and receiver modes, thus sending a signal will be more efficient.

How to change the tone of XP Startup & Shutdown

Bored with that voice-that was it when Windows is turned on or turned off.

How:

* Prepare a song or tone of what we want with the format of song / tone "wav" could take some of the mobile phone, or recorded it first. Make sure the size is too big or long the duration is not an alias for a moment.
* Once you are ready, give the name of the song or the tone with

Windows XP Startup [for the start-up tone]
Windows XP Shutdown [for the tone of the cover]

* When given a name above, now choose the second tone with Clik left and copy or cut.
* Go to localdisk / System (C), click Windows, then Media. Then copy and paste the results in the media folder. When there is a warning "if you will change the tone of the old with the new tone?, Tap Yes or Yes to All.
* Now out of the windows explorer, try to restart Windows, and listen to the results.

But this method applies when we use the standard Windows XP Theme. In fact if you want to replace all of its tone also can be prepared to stay a new tone and give the same name as the one on the Media folder

Dividing resources: for example the use of shared printers, CPU, memory, hard drive
Communication: eg electronic mail, instant messaging, chat
Access to information: for example web browsing

Based on the criteria, a computer network is divided into 4, namely:

1. Based on the distribution of sources of information / data

- Network This network consists of a centralized computer where the client and the server that the client computer that serves as an intermediary to access sources of information / data derived from a single computer server

2. Based on the geographic reach is divided into:

- Network LAN is a network that connects 2 computers or more in coverage such as laboratories, offices, and in 1 cafe.

- Network MAN network is covering a large city and its local area. Examples of local telephone networks, cellular telephone systems, as well as some ISP's internet relay network.

- WAN Network A network with worldwide coverage.

3. Based on data transmission media

- Wired Network (Wired Network) In this network, to connect one computer to another computer network cables required.

- Wireless Network (Wireless Network) is a network with the medium in the form of electromagnetic waves.

4. Based on the roles and relationships of each computer in the process data.

- Network Client-Server In this network there are 1 or more server computers and client computers. As an intermediary for the client computer can access data on a server computer and the server computer provides the information required by the client computer.

Networking-Peer-to-peer network does not exist at the client computer and server computer because all computers can do the transfer and receipt of information so that all computers function as clients as well as a server.
