The workings of Scanner
Scanner is an electronic device that functions similar to a copy machine. Photocopiers
you can immediately see the results on paper while the scanner results
displayed on a computer screen first and then only be changed and
modified to look and be a good result that can then be saved as text
files, documents and images. The
shape and size of scanners vary, there is a large folio size paper
there is also the size of a postcard, even more recently, a pen newly
launched by the company WizCom Technologies Inc. The pen-sized scanner can store up to 1,000 text pages printed and then transfer it to a personal computer (PC). Pen-sized scanner is called Quicklink. Pen scanner that measures six inches long and weighs about three ounces. Scanner is able to perform the work according WizCom randomly faster than flat-shaped scanner.
The data have been taken with a scanner that can be inserted directly into the computer applications that recognize all ASCII text.
At this time a lot of scanners in circulation in the world with a variety of brands as well, in which the output scanner from Canon, Hewlett Packard (HP), Epson, UMAX and much more.
The difference in each scanner of various brands lies in the use of technology and resolution. The use of technology such as the use of digital keys and lighting techniques.
The workings of Scanner:When you press the mouse button to start scanning, what happens is:
Keystrokes move the mouse from the computer controlling the engine speed scanner. The machine is located in the scanner control the process of sending the scanning unit.
Then the scanning unit pengiiman put into place processes or pathways suitable to immediately start scanning.
Lights seen in the scanner indicates that scanning activities have been started.
Once the lights are gone, meaning the scan is complete and the results can be viewed on the monitor screen.
If the results or display text / image you want to change, we can change this by using software applications. For example with Photoshop, Adobe and others. pot scanned.
There are two types of scanner differences in checking color image are:
Scanner that can only be a one-time scans the color and keep all the colors are at the time.
Scanner that can directly be used three times to keep some color. The colors are red, green and blue.
Scaner the former faster than the latter, but it becomes less good if it is used for color reproduction. Most scanners run on a 1-bit (binary digit / digit binary), 8-bit (256 colors), and 24 bit (over 16 million colors). Well, if we need a very good result then dianjurtkan using a scanner with a large order bit more resolution and good color.

Know the Printer and the Technology
Printer Technology
From time to time, printer technology continues to evolve so inevitably for someone who is always associated with computers and other equipment should continue to follow these developments. Printers in Indonesian language means the printer (print device). The term 'printer' is now often used to refer to the print device connected to the computer. To connect the printer to the computer needed a cable that connects from the printer to the computer's CPU. Currently, the brand products are commonly used printers include Epson, Hewlett Packard (HP), Canon, Lexmark and much more. To find out more about the function, the type of printer and printer workings, please read the continuation of this article.
Function printer
Printer is one of the hardware (hardware) connected to the computer and has the function to print text, images and other displays from computer to paper or similar media. The term is known in the resolution of the printer is called dpi (dots per inch). That is a large number of points in the area of 1 inch. The higher the resolution the better the prints produced. Conversely, if the resolution is low then the printout will be bad / not good.
Type of Printer
Dot-Matrix Printers
Dot-Matrix printers are printers that print is still very low resolution. In addition, when is printing, the printer of this type tend to be loud and sound quality is not good for printing images because the image is printed will look like dots interconnected. Generally, the printer type dot-matrix also has only one color, which is black. But this time the printer is still widely used because it is the famous 'naughty' (durable). Another plus, dot-matrix printer ribbon is much cheaper than the toner (ink) for inkjet and laserjet printer types.
InkJet Printer
Inkjet printer is a device that already prints using ink to print and print quality for color images is pretty good. Printing speed inkjet printer page count is not the same, depending on the type of printer brands. But the inkjet printer, the print is dry longer when compared to laser printers.
Laser Printer
Some of the laser printer looks like a copier. Power print is also pretty much could reach more than 10 pieces per minute. Print quality is very good laser printer, so similar to the original. Besides prints dry quickly. But the price of this printer is quite expensive.

Know the Word Processing
A word processor is an application program designed and has the function as a tool for the creation of a writing or document on your computer. The words and phrases can be made according to our wishes, either from the font, layout and more. Formerly known word processing and widely used is the "WordStar" and "WordPerfect".
Currently, the widely used word processor is a "Microsoft Word" for windows ranging from version 3.X word, word 6.0, Word97, Word2000 and Word XP now. Microsoft word for windows is widely used because it is quite complete as typing a word processing application from the simple to the complex. There was also a version of Microsoft Word that is always compatible (can be used) with the previous version.

History of Computers
If
we look at historical flashback journey of each generation of computer
development, that computer can be classified into 4 groups based on the
equipment used to create a computer as data processing equipment,
namely:
Computers using manual equipment, the purpose of the computer here in accordance with the origin of the word is "to compute" by using data processing equipment is very simple to use hand held power tools such as the traditional count known as abacus
Computers using mechanical equipment, ie a simple computing system using mechanical equipment that has been shaped and driven manually
Electronic Mechanical Equipment: In this section the history of computers has been using mechanical equipment that moves automatically by using the principles of electronics and motors for the operator to control the operation
Electronic equipment: Computer equipment where electronic data processing work as usual we meet at this time
History of First Generation Computers 1940 - 1959
In 1946 Dr. John Mauchly and Presper Eckert managed to create the ENIAC (Electronic Numerical Integrator and Calculator) and EDVAC (Electronic Discrete Variable Automatic Computer) which is pertamadengan generation computers using vacuum tubes are in the process of embryo pengembangannnya as creating computer UNIVAC I (the first computer used for commercial data processing
History of Second Generation Computers (1959-1964)
Second generation computers emerged with using transistors and diodes to replace the use of vacuum tubes that make computers smaller sizes (mini computers). This second generation has known magnetic memory storage media and have used high-level languages such as Cobol and Fortran languages for interacting machines replace an elusive
History of the Third Generation Computers (1964-1990)
In the third generation of the smallest computer types have emerged and popular microcomputers such as the Apple II, IBM PC and Sinclair. In terms of size much smaller because Chip technology began to be used to replace the transistor as a computer program logic. Variannt other programming languages have also emerged such as BASIC, Pascal, and PL / 1
History of Computers Fourth Generation (1990's)
Along with the development of chip technology that can be used to process and store the memory of the processing can be done more precisely, to the millions of bits per second. chip technology advances have led the development of computer history with the creation of a level higher Supercomputer
History of the Fifth Generation Computer
The fifth generation in the history of computer development is a dream of the future the computer at that time. It is expected that the computer can do more processing units that work together to accomplish more than one task at a time (multi-function and multi-tasking). Artificial intelligence / artificial kecerdasa is fully controlled by a computer to be a priority in this generation

Understanding computers
Understanding computers in general are tools used to process data in accordance with procedures that have been formulated where the computer itself is an electronic device that consists of several components that work together to form a working system that can run jobs automatically based on a sequence of instructions or program given to him so as to produce a program based on information and data available.
The device or component of understanding exposure dimasudkan computer input device comprising (input) such as keyboard, mouse, scanner and then the processing tool based on a CPU (central processing unit) and output devices (output) as a monitor, printer, etc. so that users can see or get the results of processing the data on a computer
Computer definition - definition of computer
The definition of computer definition has undergone several changes follow the development of the computer itself. eg first computer word he says is interpreted in accordance origin compute or to compute the mean count, so since the first computers were in use even though the term was limited to purposes such as arithmetic abacus, slide rules, mechanical calculators and other jobs that are easy to calculate and automate repetitive tasks.
