3G discussed the government and service provider technology as a must in the adoption. Did you that the maximum speed of 3G mobile phone base station to mobile at the time only 128Kbps. If you use a walking speed 3G only 384Kbps, the speed is the maximum will only be obtained if the 3G mobile phone is not the way it used at home, namely, 2Mbps.

As described in the Fund by Blair from Cisco in a presentation titled "4G: The End of the Intelligent Network", all the consequences of network-based IP, technology, which we actually use technology is the Internet Phone (VoIP) technology, especially using the Session Initiation Protocol (SIP ).

We all can take the source code and mengimlementasikan directly without the need to pay anything. Examples from the real implementation of the central 4G phone is VoIP in the People's http://www.voiprakyat.or.id motori by Anton Raharja from ICT Center Jakarta. For those of you who are interested to develop its own telephone exchange and make it to VoIP peering People can take the source code for its softswitch in http://www.asterisk.org.

Anton et al had not stopped to make a telephone exchange, and they have even more far bypassing the Indonesian government and ISPs in Indonesia with server enum build their own engine on voiprakyat.or.id. Enum is a service on the Internet that can do the mapping of phone numbers to the telcom-based SIP VoIP account. KOMINFO want a new start "PROJECT" to enum, when there are children who have been successful with both operating the enum.

How the handset to the pre-4G. For those who are still in standard tests, it can use the computer / laptop in complete SoftPhone such as WiFi and x-lite and sjphone. For those who have a PDA with the Pocket PC operating system that has WiFi capability, you can take the SJPhone software for the PPC and use your PDA as a pre-4G phones.

For those who want more serious, there are several options pre-4G phones such as Nokia E60, E61, E70 and the complete operating system Symbian OS 9.1, which supports voice communications such as Push-To-Talk and SIP. Other classes may be interesting is the Linksys WIP330 Wireless-G IP phone that is equipped for radio 802.11b / g. For those who seek to find solutions gimcrack Hop-on $ 39 WiFi Phone shapes such as nokia long, 3.5 hours of talk time or 30 hours standby. In addition, it seems to many WiFi phones are starting to enter Taiwan under the price of Rp. 500,000, -- Selengkapnya...

Before criticize about how the computer from working, we know there are good things associated with errors were found in the computer system, the error is found in various cases, better programming, and in other areas in which the process is done by using a computer.


What type of error that may be found in a process? The following types of errors that are in a process:

• Syntax error,
• Logical error,
• Run-Time error
  

The meaning of each error we see more below.

Syntax Error

The error is caused because the writing or grammar is not correct. This error makes the parties are asked to do something to be confused, so it can not do it. Examples are,

• Rice Budi eat these books, do not follow the methods of writing the grammar is correct, the truth is Budi eat rice, so we?
• Address the site is htp: / / www.hotmail.com/ there is an error in writing words that should htp is http://www.hotmail.com/
• Email is jack.febrian.com, this is not true because that is mentioned address. Truth that jack@febrian.com is, and so on.
  

When this type of error happens, the process will not be dismissed, or not to continue, until the write command confirms the command.

Logical Error

Is the type of errors in logic. If found kesalah with this type, the process still continues, but is not running properly. For example,

• Go to page 6, are on page 9. how the information you find? Of course, different with the operation you want.
• At the time of entering a data in a registration form online, Jack - say so - to fill in data on the sex accidentally and less careful with the answers women, whereas it should be filled with men. What happened? Storage process to be conducted menampikan without error, but the result? Each are welcome speech, the computer always greet, "Welcome to list Jack," ihiks ... : (
• Someone will make banking transactions online via the Internet through facilities provided by the BCA. Then he was to address a given bank, by typing http://www.kilkbca.com/ what happens? This is the opportunity dihebohkan some time ago in Indonesia, who was greeted by the site was false BCA, with a view to the same site provided by the BCA and the original site. Time to fill in his password, the owner of the site is fraudulent it can record the password was, alone know what consequences that may occur. Nonetheless, the address provided by the BCA is in Acyl http://www.klikbca.com/
  

You want to connect the mouse to the computer through a USB cable, but you colokan cable to the USB cable is connected to the printer cable is connected.
Errors in the logic of this will lead to the results of a process not in accordance with the expected general, this process does not stop because of this logic error. So, we should be careful with this error in Logic. The system will provide information in accordance with which you provide. Its accuracy is required here.

Run-time Error

This type of error due to the time a command executed, the system itself is not ready to receive this command, can only request is that you do not currently available, or because of other technical reasons. For example:


You want to listen to the radio, not connect electrical, so it must be electrical, can enjoy a new radio voice.

• Want to see news on news sites, the address is correct diketikkan, also a computer connected to the Internet, other sites visited were no problems, but the news, my site can be accessed I-Access. In fact, the server itself, news sites that are down (the term used if the server is not active or dead)
• When the roads are in the Internet, you are interested in a picture or information, and you want to save it to disk, but to save time, my information has always failed. Floppy disk is entered correctly. In fact, the cause is a damaged disk is used.
  

Error type of run-time error resulted in this process is terminated immediately, the system generally notify the condition of knowing if this problem is found. Selengkapnya...

PLC (Programmable Logic Controller) introduced the first time in 1969 by Richard E. Morley is the founder of Modicon Corporation. According to the National Electrical Manufacturing Assosiation (NEMA) PLC is defined sebagasi a digital electronic device with a memory that can be programmed to store instructions that run specific functions such as logic,

Sequence, timing, counting, arithmetic and to control a machine or process industry industry in accordance with desired. PLC is able to do a process of continuously variable inputs and appropriate decision according to the desire to provide programming so that the value of output remains controlled.

PLC is a "special computer" for application in the industry, to monitor the process, and to replace the hard wiring and control has its own programming language. PLC but will not be the same as the personal computer PLC is designed for installation and maintenance by engineers and experts in the electricity industry that should not have the skills electronics and high flexibility control logic based on execute the instructions. Therefore, the PLC-day growing both in terms of the number of input and output, the amount of available memory, speed, communication between the PLC and programming techniques or methods. Almost all production processes in the industry can diotomasi using PLC. Speed and accuracy of operation can be improved far better to use this control system. Excellence from the PLC is the ability to change and falsify the operation at the same time with communication and information-collecting vital information.


Operations on the PLC consists of four important part:

1. predictive value of observation

2. run the program

3. value of output

4. control

From the excess above the PLC also has shortcomings, among others, which often highlighted is that for a PLC memrogram needed someone who is very professional and understand what is needed by the factory and understand about the safety or security that must be met. Meanwhile, people who trained as it is quite rare and in pemrogramannya must be done directly to the place where the server is connected to the PLC, while it is not uncommon location of the main computers in places dangerous. It is therefore needed a device that is able to observe, to edit and run programs from the distance. Selengkapnya...

1. Create desire
So ... first, munculkan I wish you the self. For example, you want to make a report, there must be a determination that round (he's not the triangle ..).So that a determination appear to imagine that the results will be obtained if you do these reports. For example, all people will amazed ..

2. Create pain
Once there is a determination, try to imagine if you do not make the report .. what will happen? imagine the bad-bad. As will be the value of E (god forbid a newborn baby?).

3. Discuss your plans
This was ... you plan on talking about other people. Who know they want to help you. or at least with our people on the other side, we can ask for support and motivation or enthusiasm.

4. Have a real interest
Oops .. not until there is no interest at all. Do not do something with forcing elements. The result will not be in accordance with our desire.

5. Have energy
Create your spirit! Do not until the conditions are less fit you into the barriers in themselves.

6. Create a mental balance
So .. This related to the spiritual. Eliminate poorly thought-mind. Eliminate negative nature thingking. You can quickly parents: D]

7. Take a small step
Finally ... .. start with small steps first. For example, the case for making the report .. should not be forced to take on the discussion. the stress before you can solve them. Start with the goals and basic theory.

Good luck Selengkapnya...

Why should this be learned? :)

• The goal is to make us better understand the origin from which the technology that we use sekaran
• Some of the technology that is considered ancient, but still used,
• By knowing the origin and development of the technology will be more easier to predict what will happen to the future
• Interesting to watch!

Evolution

Since yore, the data processing has been done by humans. Humans also find tools for mechanical and electronics to help people in the calculation and data processing that can get results more quickly. Computers that we had when this is a long evolution from the discovery of human sejah-old form of mechanical or electronic means.

Currently, the computer and its tools have been included in every aspect of life and work. Computers are now have the ability more than usual math calculations. Among them is a computer system in kassa supermarkets that are able to purchase goods code, telephone exchange, which handles millions of calls and communications, computer networks and internet mennghubungkan various places in the world.

However the data-processing equipment from the primeval since until this moment we can grade into 4 large groups.

1. Equipment manual: data processing equipment that is a very simple, and the most important factors in the use of tools is to use the power of human hands
2. Mechanical Equipment: the equipment that is shaped with a mechanical hand moved manually
3. Mechanical Electronic equipment: equipment mechanics, which is driven by a motor automatically by electronic
4. Electronic equipment: Equipment that works in electronic full.
   

Computer Generation

Early-generation computer starts since the computer that created by humans begin using the concept of Stored program in 1946.

Although previous work has various types of computers, such as analog computer in 1931 by Dr. Vannevar Bush at the Massachussetts Institute of Technology). Then, the first electronic digital computer by John V Atanasoff in the finishing of the 1942, the computer is a computer-birth of the first generation of computers.

Generation Mainframe

1946 is the beginning of the first generation of computers, generally begins with the ENIAC (electronic Numerical Integrator and Calculator). Computers in this period have thousands of empty tube to a computer, the physical size is large enough, and need a place large enough. Generally, this computer is used to calculate the accuracy of the shot. Want to know how this computer program? And that is by connecting cables and cut and use the contacts.

Computers in this generation is still slow process, and consume electricity that is high enough, and still save a little power. ENIAC own at the time it requires a place where more than 500 m2, and use the empty tube. ENIAC is not the only computer in this generation. Besides there are still ENIAC computer that appear, among which are:

• EDSAC (Electronic Delayed Storage Automatic Computer), a computer with Stored program first. The computer was made by the mathematician John von Neumann and teamnya. This made the computer since mid-1940 and operated in 1949 at Cambridge University, England.
• ACE (Automatic Calculating Engine) created by Alan Turing M since 1945, this computer has been implementing the use of the card plong as the media for input and output it.
• SEC (Simple Electric Computer) is a computer that uses magnetic drum as a storage memory. This computer is made in 1950 in Electric Computer Laboratory of Birkbeck College, University of London.
• LEO (Lyon Electronic Office), 1951, is the first commercial computer in the UK.
• EDVAC (Electronic discrete Variable Automatic Computer), 1952, is a computer program Stored first made by the United States.
  

Generation Minicomputer

Computers in this generation is a refinement of the previous generation of computers. The language used is no longer a pure machine language, but language is to use a high level, making easier in the program. The components used have already started using the transistor so that they can make the computer the size is much smaller compared with the first generation of computers. This generation is a generation emerging minicomputer, and prices are much cheaper when compared with the previous generation. Computers in a generation that is:

• PDP-1, manufactured by DEC (Digital Equipment Corporation) that are introduced in 1959,
• PDP-5, is the first mini-computer,
• UNIVAC III,
• IBM 7070
  

Microcomputer generation

This generation marked by the use of IC (Integrated Circuit) that is able to accommodate some electronic components at once in a very small size, of course, with this size computers also make direct far smaller than the previous generation computer, as well as the use of electricity decreased dramatically. IC own first made by Jack Kilby in the year 1958. Computers that appear in this generation are the IBM S/360, which is a third generation computer first. Besides, UNIVAC 1108, NCR Century series, dlsb.

Innovation is important in this generation is software compatibility, among several machines.

Generation Internet and the Web

This generation starts since 1970, the usage of Large Scale Integration (LSI). At this time bermunculanlah computer macro (macro computer). Intel issued a first processor in the world, known as the Intel 4004 in 1971. In the year 1977, Apple issued a personal computernya the first. This generation has allowed a computer without the software, and software must be programmed using assembly language.

The development occurred not only in the engine computer itself, but also meaningful to the computer network. Local Area Network began to be implemented in many places, and the United States Department of defense also began using the Internet Protocol.

Generation Pervasive Computing

This generation is a generation that started out the use of the computer desktop. Various technologies were found to implement a computer with other technology, in a very small size, and ability are smart enough. Where in this generation, someone no longer use the computer while sitting dikursi and to the computer on the thoughts, because the computer has joined with various devices such as palmtop, mobile phones, etc.. This technology also has been able to connect one device to another device using the internet point.

Changing Economics generation of Computing

In this generation of economic changes occur field of computing. The first komptuter prices so high, because of size, ability dlsb, the current price of the processor, memory and other devices are very cheap. Plus diimplementasikannya biotechnology or bioinformatik. Where in a period of the previous technology is not considered possible, at this time is not something that can be possible. Informatikawan including the desire to create a computer that more people can afford to develop themselves in accordance with the technological capabilities at the time. Selengkapnya...

A price of success
In a seminar, a famous motivator to get started with a piece of money Rp.100.000, -. He was raising money to high-level, while submitting a question to more than 2,000 participants of the seminar. "Who wants this money?"

Surefire most of the participants shake hands.


Motivator is ever, "Good! I will give this money to one of you. But before that I will do something. "

Motivator the rolls of paper money is. Once again, the less he asked, "Who still wants this money?" No different from the previous, almost all participants of the seminar is shake hands, the money they still want it.

See the response of participants has not changed, the motivator and trample down the money with the right leg and foot with the left. After the money was dirty and disheveled, he again asked, "Is there still a mengingkan this money?"

Still the same as the previous, almost all participants shake hands. Then he said, "My best friend, and from modeling I was just want to show that siapun want to have the money. However, the money will not reduce the value of Rp. 100,000 - "

Message:

The story explains a truth that life is indeed difficult. Every day we face challenges of small, medium, heavy, up to very heavy. But basically, the challenge is not to reduce the value of life we as human beings. In the challenges of life is necessary to increase the value of ourselves.

"The ultimate measure of a man is not where he stands in moments of Comfort and Convenience, but where he stands at times of challenge and controversy. - The value of a human being can not be measured while he is in the comfortable zone, but how he confronted the challenges and kontrovesi, "said Martin Luther King Jr..

But very many of us complained that only a life full of challenges. They must forget the challenge of learning something, the pain and struggle of life. Because if everything is perfect in this world, then we will not be able to learn new things or get a larger spirit to do better and improve value ourselves as human beings. Selengkapnya...
