Tips Reducing the Impact of Radiation Monitor


how to minimize the radiation so it does not cause eye damage? The following will explain some tips.
  1. Choose Monitor Low Radiation
    Choose a computer screen that low radiation power, such as LCD or LED. The resulting radiation power is smaller than the CRT monitor models. If you still have had to use a CRT monitor / tube. use a 75Hz refresh rate, or more because the refresh rate can damage the eye.
  2. Consider Room Lighting
    The lights are too bright dark atupun easily cause eye fatigue. Adjust the room lighting is adequate so that the eyes do not have to work hard in the face of the monitor.
  3. Arrange Lighting Your Computer
    Adjust contrast and brightness of your computer so that eyes feel comfortable when using computers.
  4. Wear sunglasses with Special Lenses to Computers
    Currently, several companies have made the upper part of the lens is designed to look at the computer, while the bottom for reading.
  5. Silicon Hydrogel Contact Lenses
    For contact lens users, could use a new generation of contact lenses made from silicone hydrogel. Silicon allows a higher transmission power than other types.

After using the computer for several hours, rest your eyes for a moment, then resumed again. Prevent damage to our eyes early on, before it's too late!

Understanding Wireless

Wireless is a connection between a device with other devices without using cables.Wireless Personal Area Network PAN is connected to the wireless media. Wireless technology used in this PAN is IrDA and Bluetooth.Wireless LAN is connected via a computer network without wires. Local Area Network of computers and other devices that communicate via radio signals or light waves. This system is useful when connecting via cable or fiber optic connection is quite expensive, or to move the connection application. Data communication technology with no cables to connect between the client and server. Wireless LAN technology in general is similar to a computer network technology that uses a cable (Wire LAN or Local Area Networks). Wireless LAN technology is using radio frequency to send and receive data that would reduce the need for or dependency relationships through cable. As a result, users have high mobility or flexibility and not dependent on a place or location. Wireless LAN technology is also possible to form a network of computers that may not be accessible by computer networks that use a cable.Wireless Card is a card that is used to support the computer can be connected in a network.

Intel vs AMD Processor Comparison



Both Intel and AMD use different views to the processor, the architecture of the processor itself. In this case, nothing can be said to be superior or not. AMD integrates the memory controller into its processors, so that the data path between the processor with the chipset to be shorter. Intel does not integrate the memory controller into the processor (although now that view has changed with the presence of Core i7 / codename Nehalem) and focus more on growing internal memory on the processor. Both Intel and AMD, have their respective advantages. For AMD, the cultivation of the memory controller is often referred to as HyperTransport into the processor makes data transfer rate is faster (because it does not have to wait for the data from main memory), but it makes the internal memory on the processor becomes small. For Intel, the integration of the processor internal memory (obtained from the cultivation of a large number of transistors) makes it powerful in terms of multi-threading applications as it pertains to the primary function of the internal memory of the processor itself (as a temporary data storage to be processed by the processor), but less Digdaya in its price range. I as the authors acknowledge, with Intel over AMD technology level. Therefore,

History of AMD

AMD processors are the most stringent competitor for Intel processor. AMD has always made ​​a faster processor than Intel. That's why AMD is more suitable for gaming and running heavy applications (such as 3-dimensional simulation). But because AMD is always faster than Intel, then AMD is less well-known heat stable and faster. Can be said if the issue of speed, AMD came out ahead. But the problem of durability and stability, more unggul.Selain Intel's, AMD is always cheaper than Intel processors, although the same processor speed.

The History of Intel


  1. In 1971, Intel issued a series MCS4 processor that is the forerunner of the i4040 processor. 4-bit processor is planned to be a brain calculator, the same year (1971), made revisions to the intel i440. Originally ordered by a Japanese company to manufacture calculators, it is much more powerful processors than expected, so Intel bought the rights to those of Japanese companies for the development and further research. This is where the precursor to the development towards a computer processor.
  2. In 1972 appeared the first i8008 8 bit processor, but somewhat less preferred because multivoltage and emerging i8080 processor, here there are so triple voltage changes, use of technology NMOS

The fifth generation computer


Defining the fifth generation computer becomes quite difficult because the stage is still very young. Imaginative example of fifth generation computer is the fictional HAL9000 computer from the novel by Arthur C. Clarke entitled 2001: Space Odyssey.
HAL displays all the desired functionality of a fifth-generation computers. With artificial intelligence (artificial intelligence), HAL may have enough reason to do percapakan with humans, using visual feedback, and learn from his own experience.
Although it may be the realization of the HAL9000 is still far from reality, many of the functions that had been established. Some computers can receive verbal instructions and are able to mimic human reasoning. The ability to translate a foreign language also becomes possible. The facility is deceptively simple. However, such facilities become much more complicated than expected when programmers realized that human understanding relies heavily on context and meaning rather than simply translate words directly.
Many advances in the field of computer design and technology

The fourth generation of computers


Several vendors announced "fourth-generation computers" and some of the announced "fifth generation computers". This is just a market strategy. Three generations of technological breakthroughs previously distinguished with important electronics - vacuum tubes, then transistors and integrated circuits. The fourth generation came with the development of a less striking, only in the form of computers and software have advanced somewhat, and this generation of computers may not be as lucky as the previous generation in terms of 'rule' the world market before the next new technological breakthroughs. This is why some people often refer to this generation as the generation of 3 ½.
Micropocessor
One of the many contributions in the appearance of the next generation of computers is the microprocessor. Microprocessor contained in a single silicon chip. Microprocessor was first demonstrated by Texas Instruments in 1971. The price could be a few dollars and can be found in any of the machines to satellites.
Microcomputer
Processing tool is a small, relatively inexpensive, but high performance. Microprocessor 'contained' in

The third generation computers


Although the transistor in many cases have exceeded the ability of a vacuum tube, but the transistor is too large to produce heat, which could potentially damage the parts inside the computer. The stone was discovered later quartz or quartz rock that can eliminate this problem. An engineer at Texas Instruments, named Jack Kilby developed the integrated circuit (IC: integrated circuit) in 1958. IC can be combined three electronic components in a small silicon disc that was made from quartz. then the scientists managed to fit more components into a single chip, called a semiconductor. so as to produce a computer that is getting smaller because the components therein can be squeezed onto the chip. The third-generation development to

Second Generation Computer


1948, the invention of the transistor is very influential on the development of the computer era. Transistors replaced vacuum tubes in televisions, radios, and computers. so the impact on changes in the size of the electric machines which initially has a large size into smaller size.
The transistor used in computer technology began in 1956. Other findings in the form of magnetic core memory, a second generation computers smaller, faster, more reliable, and more energy efficient than its previous predecessor. The first machine that can take advantage of new technologies is a supercomputer. IBM created a supercomputer named Stretch, and Sprery-Rand called LARC. This computer, which was developed for atomic energy laboratories, could handle large amounts of data, a capability that is needed by atomic scientists. LARC computer machine was very expensive and tend to be too complex for business computing needs, so that its popularity is limited. There are only two LARC ever installed and used, ie, one

The first generation of computers


Beginning on the first generation computers was during the second world war, the countries involved in world war that sought to develop computers to maximize the ability to set the strategic importance by the computer. This affects the increase in funding for computer development also participated accelerate the growth of technical progress. In 1941, a German engineer named Konrad Zuse built a computer, the Z3, to design airplanes and missiles.
Elsewhere there allies Parties are also others who are also making progress in the development of computer capabilities. In 1943, the British successfully completed a secret code-breaking computer called Colossus given that serve to break the secret code used by the German state. Effects of The Colossus is actually not much affect the development of the computer industry, it can happen for two reasons, namely: the first, Colossus computer is not versatile in the English language "general purpose computer", he made only in order to solve the secret code. Secondly, the existence of the machine was kept secret until decades after the war

historical development of computer


Today who is familiar with computer advanced tools that can make anything, could make office work to assist the process in the factory. In addition to today's computers are also for entertainment and play game.Komputer are tools used to process the data according to the orders that have been formulated. Said the computer was originally used to describe people who perkerjaannya perform arithmetic calculations, with or without a walker, but the word is then transferred to the machine itself. Originally, the processing of information is almost exclusively related to arithmetical problems, but modern computers are used for many tasks unrelated to mathematics.
To discuss the article about the history of computer development is not separated from the discoveries of mankind since time immemorial in the form of mechanical or electronic means. Computers are commonly used today is a long evolution from the previous computer since it was first created in which the computer is very limited due to the use and usefulness has not been commercialized and memerlukam special skills to
