barcode is divided into two types based on its dimensions are one-dimensional (1D Linear barcode) and two-dimensional (2D-Matrix Barcode)The following is a breakdown by dimensions:
A. ONE-DIMENSIONAL (1D - LINEAR BARCODE)
-Code 39,-Code 128,-CodaBar,-Code 25 (Interleaved 2 of 5 / ITF),-Code 93,-Code 11,-ITF-14-EAN-8,-EAN-13-Jan-8,-Jan-13-UPC-A,-UPC-E,-ISBN,-ISSN,-Logmars,-Plessey,-Telepen,-FIM,-Pharmacode,-Postnet,

B. DUA DIMENSI (2D – MATRIX BARCODE)

-QR Code, -Micro QR Code, -AZTEC Code, -Code ONE, -Data Matrix, -Grid Matrix, -PDF417, -MicroPDF417,

and this is the advantage of using barcodes
- Process Data Input more quickly, because Barcode Scanner can read or record data faster than the process input data manually
- Process Data Input more precise, because the barcode technology has a high accuracy in the search data
- Information search more accurate data for barcode technology has the accuracy and precision is very high
- Reduce costs, because it can avoid the loss of data recording errors and reduce the work is done manually and repeatedly
- Improved performance management, because the data faster and accurately then the decision by management to be much better and more quickly, which will be very influential in determining the policy of the company
- Have higher bargaining power or prestige and the ability to compete with rivals or competitors will be more awake

Pengertian dan Jenis-Jenis Lan Card

Definition and Function Lan Card

 
Card Lan (local area network) or network card is the gateway to the network on a computer, any kind of network activity require land card Land card internet.dengan other words it can be called a bridge from a computer to a network komputer.Lan is limited because it only can be used in a limited area, such as houses, buildings, offices, restaurants dll.berbeda with a WAN (wide area network) that covers a wide area telecommunications network that connects every crosses the boundaries of metropolitan, regional, national and other internasional.perbedaan is that common LAN technology that operates at Layer 1/2 (such as Ethernet or Wifi form) often directed local physical network, and therefore can not transmit data through dozens, hundreds or even thousands of miles or kilometers.
Type - Type Lan Card:

 

1.Lan ISA

Lan ISA is the first generation that is produced by a company with a network card slot solid black numbering one to three slots.

2.Lan PCI

Lan kind it is the replacement of the previous Lan Lan ISA, this type was produced around 1992, and was used on the motherboard start pentium one to date dross ini.Namun significant difference from the old motherboard and the latest can be determined by the number of PCI slots, old motherboard has more than three PCI slots, but for the most recently there was only one PCI slot.

3.Lan Card USB.

Lan Card is the best solution if the user runs PCI.Lan Card slot type is more simple as it can to the USB port, if you want to buy this type lan I recommend buying the brand Logitech, Fujitsu, D-Link.

4.PCI Wirelless LAN Card

One type is now more popular, the network dibanguntanpa using cable media but uses wirelless media, so in addition to the USB Wirelles this could be an alternative. With this type of mounting her on a PCI slot but its output antenna wirelless.

PENGERTIAN ROM DAN JENIS-JENISNYA BESERTA CONTOHNYA

PENGERTIAN ROM DAN JENIS-JENISNYA BESERTA CONTOHNYA

understanding ROM
ROM stands for Read Only Memory, which is hardware in the form of computer chip semiconductor memory whose contents can only be read. ROM can not be classified as RAM, although both have in common that can be accessed randomly (random) .ROM different from RAM.The difference between the two, among others:
1. ROM can not be filled or write the data at any time as RAM. Charging or writing data, information, or program in the ROM requires a special process is not as easy and as flexibly how to write RAM. Typically, data or programs that are written on the ROM filled by factories that make them. ROM is generally used to store firmware, the software associated with hardware. Examples of this kind is the ROM BIOS ROM. ROM BIOS contains the basic program a computer system that serves to organize and prepare all equipment or components or installed on the computer when the computer is "turned on / on '.
2. Information / data / programs that are written on the ROM (ROM contents) is permanent and not easily lost and not easily changed even though the computer 'turned off' or off (off). While in RAM, all of its contents (either in the form of data, programs or information) will disappear by itself if the computer is 'switched off' (in the off state).
3. ROM can store data without the need for power. That is why the data in ROM will not be lost even if the computer is off. While RAM requires power in order to store the data, if the RAM is not getting power, by itself would not be able to store data. This is what causes the data contained in RAM will automatically disappear when the computer is off (off).
4. Modern ROM is often found in the form of IC (Integrated Circuit), the same as his form Yag RAM also mostly in the form of IC. Text or code written in both types of IC is different. IC ROMs usually have a code text (text) 27xxx. Figures 27 shows the code to ROM, while ROM capacity dalan menjunjukkan xxx units kilo bits.

function ROM
As has been previously disclosed that the ROM is generally used to store firmware. On the computer, are often found to store the BIOS. At the moment a computer is turned on, the BIOS can be directly executed quickly, without having to wait for a turn on the first storage device sepRead Only Memory is a hardware form of memory that can only be read. At the ROM, we can not fill or write the data at any time as the RAM. although both are equally accessible acak.memori this type is slower, but the data in ROM will not be lost and not be changed while the computer is off / off because ROM can store data without requiring electrical power. The modern form of the ROM is frequently found in bentu IC (integrated circuit). Function than the ROM is the storage of firmware, the software (software) associated with the hardware (hardware). such as the ROM BIOS, the BIOS which can be directly executed quickly, without having to wait for a turn on the first storage media devices such as would occur in other storage devices. Although the ROM memory as read-only, but the data on this memory can be rewritten.
Read-only Memory (ROM) is an English term for computer data storage medium. ROM stands for Read-Only Memory, ROM is one of the computer's available memory. This ROM is permanent, meaning the program / data stored in ROM is not easily lost or changed while power failure.Storing data on the ROM can not be done easily, but the read data from ROM is easy. Usually the program / data in ROM is filled by factories that make them. Because of these properties, the ROM is used to store the firmware (software that is closely related to hardware).One example is the ROM BIOS ROM which contains the basic program a computer system set up / prepare all equipment / components in the computer when the computer is turned on.Modern ROM found in the form of IC, exactly as the storage medium / other memory such as RAM. To distinguish it needs to read the text that appears on its IC. Usually starts with 27xxx, number 27 indicates the type of ROM, xxx indicates the capacity in kilo bits (not kilo bytes).
Some ROM type:
Mask ROM is a ROM that can not be rewritten (non-flashable), so there can be up-grade.
PROM (Programmable Read Only Memory) is a type of ROM read-only data. PROM classified as non-volatile memory, the data / information / program that will not disappear even if your computer is switched off / off (do not get electric power). so the data contained in this memory is permanent
EPROM (Erasable Programmable Read Only Memory) is a type of memory writeable ROM program / data electrically. Data / information / program may be lost / deleted when exposed to ultraviolet light. EPROM including non-volatile memory, together with PROM, the data will not be lost when the computer turn off / not got power.
EEPROM (Electrically Erasable Programmable Read Only Memory), the same as PROM, and EPROM, EEPROM is still relatively non-vilatile.
EEPROM is a component that is widely used in electronic equipment fatherly store configuration data. EEPROM capacity is limited, the system hardware typically used to store configuration data and settings related BIOS. penghausan process data at faster than EPROM EEPROM for data can be electrically erased with ultraviolet light. Rewrite EEPROM is a tool to delete the data in the EEPROM. Examples of memory similar to EEPROM is Flash Memory. That type of ROM that can be rewritten. Typically used in digital cameras, Mp3 applications, mobile phones, flash, etc. erties common to other storage devices other than ROM.
Generally, on other storage media, if executed to read the contents or data, the storage media must be turned on first before read, which of course takes a little longer. Things like this do not happen in the ROM.
On a computer (PC) modern, stored in the BIOS ROM chip electrically re-writeable known as Flash ROM. That is why the term is more popular than the flash BIOS ROM BIOS

Jenis Scanner dan Fungsinya

Scanner or the scanner in the Indonesian language is a tool and computer hardware, which acts as an input device on the computer.

Scanner functions

This scanner device is used to scan documents or physical objects, and convert it into digital form and stored in the computer.

Scanner itself turned out to have many types and shapes, not as we imagine today. any type - the type of scanner? Here is bberapa types of scanners:

1. Scanner Drum

The first type of scanner is a scanner drum. As the name implies, this type of scanner is a scanner that looks like a drum, aka tube. This scanner is basically a type of scanner that is remarkable, especially in terms of image resolution can be generated. This drum scanners supposedly he is able to produce images and also scans the resolution reached 24,000 ppi or pixels per inch. It berarati shows that the quality of images produced by the media drum scanner is so incredible detail and clear, and really - really high resolution.
The advantages of Drum Scanner
The drum scanner certainly has some advantages. In addition to having scanned images with high resolution, up to 24,000 ppi, drum scans also have here a couple of advantages, such as:

    Able to perform the scanning process on the document as well as a flat object or a large sheet of paper
    Minimal vibration, so that the results of the scan will not experience distortion and vibration
    Very fitting to obtain maximum image results from a document
    Useful for emlakukan scan the fragile ancient documents
Disadvantages of drum scanner
Although it has many advantages, especially in terms dar results generated image resolution, drum scanners also proved to have some drawbacks. Here tends to some shortcomings of Drum Scanner

    The physical form of a scanner is very large, making this tool becomes very impractical for everyday use - day
    Price scanner tools are extraordinarily expensive and difficult it is to obtain a drum scanner
    Limitations of obejk can dipinda or in scan.Jenis first scanner is a scanner drum. As the name implies, this type of scanner is a scanner that looks like a drum, aka tube.

2. Scanner Flatbed

The next type of scanner is a flatbed scanner. Known as a flatbed scanner as this scanner is a scanner that looks flat and too flat, like beds. This is a type of conventional scanners are common and are easily found in the world and also the world of office document scanning. Is a kind of scanner that is most widely used, and are also used, as it has a small size and compact, and is compatible with several standard paper sizes, such as legal and also letter, up to A3 paper. Flatbed scanner uses CCD technology or Charge Coupled Device as the eye can scan the document placed in it.
The advantages of a flatbed scanner
Flatbed scanner itself has several advantages, which make it very popular types of scanners, such as:

    Price is relatively cheaper than other scanners
    Compatible with a variety of computer operating systems
    Can scan and scan any paper type that has a definite size
    Saving electricity and also power
    The result of the resolution of the object that is pretty good
Kekuangan flatbed scanner
Although emmeiliki many advantages, flatbed scanners also have some kelemahaan. Here are some of the weaknesses of the flatbed scanner:

    Just can perform scans on only one side of the object
    Is not very effective in doing the scanning of many obejk

3. Film Scanner

may now use negative fil technology to store photos and videos also are very rarely used. Even so, perhaps adna want your old memories that are still in the form fil negative, to be stored on your computer, and you print at any time by using your printer. Well, the film scanner is a very precise answer. Film scanners use the same technologist as flatbed scanners, the CCD as an eye scan, but is specific to the object whose shape tends to negative films.
So, Film Scanner is able to convert and also alter the objects stored in the film negative to digital form, and you save on your computer.
While these tools emrupakan a very useful tool for personal gain, however, the price of the film scanner speckle is quite expensive, and also may be a little difficult to obtain. In contrast to the flatbed scanner that you can find easily anywhere.
In addition, the film scanner jga have limited functionality, which is only capable of scanning the negative film form only, and not the other document types.

4. Roller Scanner

Roller Scanner is a kind of scanner that functions the same as a flatbed scanner, which is to perform a scan on a document or an image that physically shape the sheet or object that is easy to scan. The main difference between roller scanners and flatbed scanners are of the method used.
If the flatbed using CCD technology has become the "eyes" that move - motion in scanning the contents of the document, then the scanner roller mnggerakkan no eyes, but the document yagn driven. It works just like a printer, where the document or paper is placed on the other end, then the paper will be entered into the scanner, and then exit at the other end.
Scanner roller is divided into two types, namely:

    Scanner ADF (Automatic Document Feeder
Scanner is a kind of roller intended for use in a large number of documents. These scanners have a separate container for storing the document to be scanned, and then automatically all of the documents will be drawn into the machine Roller Scanner gradually one by one.

Pengertian VGA Card Komputer Dan Jenisnya

Definition VGA card computer and type
VGA card or the like is also called VGA card, abbreviated from "Video Graphics Accelerator" the functioning of the process data graphics to be displayed on a computer screen. VGA prossesor also has what is called the GPU "Graphics Processing Unit" and also requires memory. VGA card serves to translate the computer output to the monitor. For the graphic design process or playing a video game, etc., required high-powered graphics card.
Function Card VGA (Video Graphics Accelerator) is to translate or convert the digital signals from the computer into graphical display on the monitor screen. VGA card also has a function to translate the computer output to the monitor. To play video games, create graphic design and so on.
Types VGA On Computer include:
   1. ISA VGA card is a type of card VGA (Video Graphics Accelerator), which is inserted in the expansion slots ISA (Industry Standard Architecture) bus is still bersistemkan I / O 8-bit or 16-bit.

   2. EISA VGA card is the type of card Video Graphics Accelerator, which can be attached to the expansion slot EISA (Extended Industry Standard Architecture) bus is a 32-bit I / O system.

   3. PCI VGA card is the type of card VGA (Video Graphics Accelerator) mounted on a PCI expansion slot (Peripheral Component Interconnect) bus is 32-bit or 64-bit I / O system.

   4. VGA card is AGP VGA card types that can be attached to the expansion slot AGP (Accelerated Graphics Port) bus is 128-bit and 256-bit I / O system.

  5.  VGA card PCI Express (PCIe) is a type of VGA card that can be inserted in the expansion slot PCIe (Peripheral Component Interconnect Express) bus which is berangkaian series I / O system with its transfer speed reaches up to 32 GByte / s.

VGA card shape, covering:
VGA cards are divided into two (2) types according to their form, ie VGA card on board and add-on VGA card. VGA card on board can you find in all the motherboard / mainboard when you buy a computer or laptop because they were a package deal. This VGA can you use to display the output on the screen very well. Actually, if you do not do high-level graphics processing, we do not require add-on VGA card. If you feel the on-board VGA card is less than the maximum or less sophisticated, you can add the add-on VGA card. It is primarily for you graphic designers, 3D game player, movie editor, etc.
Therefore, the presence of the add-on VGA card is according to your needs. When it is apparent that the VGA on board you will not be able to do what you need, then the add-on VGA card can be added. But this only applies to the PC (Personal Computer) just cause to other devices such as laptops are not available card slot for additional add-on VGA card. Moreover, the add-on VGA card also makes the need for electrical power on the computer to be high and this can only be met by a PC only
Weaknesses and strengths of each of the VGA card
On-board VGA card has the advantage of already bundled with mainboard / motherboard, so it certainly will not be any problems with your computer when it is used. Moreover, the on-board VGA card can be said to be free. Every time you buy a motherboard, VGA card must have been installed on-board. Of course, this is very good for you that have budget / funds are limited in buying a computer. While shortcomings of on-board VGA card is not having its own memory. This resulted in "cutting" the memory of the main CPU or your laptop, known as RAM (Random Access Memory) for use by VGA. If RAM is limited, of course, overall PC performance will be slowed down.
As for the add-on VGA card that excess is able to do the job of rendering heavy and also not "eat" the main memory or RAM in the CPU (Central Processing Unit). A process that involves the graphics will not overwhelm computer processors and you will be faster in the process something. The disadvantage is the price is a bit expensive, even more expensive than a set motherboard / mainboard coupled with the processor and RAM. In addition, other drawbacks that make your computer requires electrical power somewhat larger than usual. If you have a power supply capacity is not great, then the performance of the PC / computer will not normal, so that you are required to replace the power supply with a somewhat higher and this certainly do not come cheap or expensive.

Pengertian Printer dan Jenis-Jenisnya

Who does not know with Printer, hardware bebentok this box. Understanding of the printer itself is a hardware or hardware that is connected to a computer where the function of the printer is to produce good mold the mold is in the form of texts or images from a computer using sejanis paper or other media. Dariprinter have 3 types namely Dot Metrix, Ink Jet Printer and Printer lase jet

 .

Printer Dot matrix 

Dot Matrix Printers can we know with typical prints of which looks like a point - a point that interconnect with each other so that the prints are less smooth and less good. These types of dot matrix printers use a printer printing method using tape. If we trace the history of the printer dot metric initially using the 9 pin that has maksut that a letter would be printed with a combination of 9 points. Once over the development period metric dot printer uses 24 pins and of course the result would be better and smoother. Manufacturers of this type of metric famous dot printer is Epson.

Printer Ink Jet

Type Ink jet printer is a printer type printing method using liquid ink. If viewed in terms of results produced an ink jet printer, the printer of this type is better and better results when compared with the previous version of the printer is a dot matrix printer. Ink jet printers can also print documents such as pictures or color. Ink jet printer itself using technology dor on demand, meaning by spraying tiny dots on paper via noxxle or holes in the pipe was very small. Manufacturers with ink jet printe famous canon is a manufacturer and HP using heat. The heat can make bubbles of ink so that if more heat will further depress the ink to the nozzle is determined and printed on paper. For use with liquid ink cetakannyapun result in required to wait a few seconds in order to dry and utterly inconceivable dry. This type of ink jet printer using the ink charging infusion techniques or modifications.

Printer Laser Jet 

Laser jet printer is a printer that uses ink powder printing method or commonly called toner using infrared device. Viewed in terms of results produced Laset jet printers certainly better compared to ink jet printers and dot matrix

PENGERTIAN RAM Dan JENIS-JENISNYA

Understanding RAM
Understanding RAM is a hardware device that serves to store data and program instructions that will and already executed by the processor. RAM is temporary storage, this means that after the computer is turned off, RAM will be cleared and will be filled with new data that is required when the computer switched on and used. Own RAM stands for Random Access Memory. In contrast to magnetic tape or disk to be accessed sequentially, the contents of RAM can be accessed randomly, or do not refer to the location of the data. This makes RAM is faster than hard disk or other storage medium.
RAM itself is often referred to as main memory or main memory, main memory or primary memory or internal memory, or simply called a memory, although there are several types of memory installed on the computer. RAM function is supporting the processor in the processing of data and instructions in which it stores data to be and have been processed by the processor. Without RAM, a computer can not work because nothing accommodate input and output processor. RAM and processor must keep pace. Fast processor requires a large RAM to be able to work more optimally. The processor is slow given the huge RAM will be useless, although there is an increase in performance, but not significantly. For that there is a size limitation of RAM that can be used by the processor. Module capacity expressed in units Byte RAM, such as 256 MB, 512 MB, 1 GB, 2 GB and so on.Types of RAM
The types of RAM include:

   1. NV-RAM is the memory used by the BIOS (Basic Input Output System) to save the settings, this memory requires a power supply so that the savings are not lost. Therefore, in every computer there must be a small lithium battery that is used as a power supply NV-RAM.

   2. SRAM (Static Random Access Memory) is a type of RAM that is made from a kind of semiconductor that requires no capacitors and does not require periodic refresher so much faster. However, SRAM has a weakness, namely the cost of production is expensive so it is only available in a small capacity and a handle portion which is really important.

   3. EDO-RAM (Extended Data Out Random Access Memory) is the first generation that replaces RAM FP RAM in the CPU. This memory has a small capacity and capability. This type of RAM is not produced, the last work on computers with x86 processors such as the Pentium generation of the early start I and II.

   4. DRAM (Dynamic Random Access Memory) is a semiconductor memory that requires a capacitor as a pedestal to refresh the data in it. RAM has a speed higher than EDO-RAM. But lower than SRAM. In its structure, DRAM requires only one transistor and a capacitor per bit, so it has a very high density.

   5. DDR SDRAM (Double Data Rate Synchronous Dynamic Random Access Memory) is the development of DRAM that uses synchronous data transfer system but has a data transfer speed is doubled. This memory is generally only referred to as DDR and has three versions, DDR1, DDR2 and DDR3. Each difference is a problem of data transfer speed and PIN number that is on its feet.
