How to enter Safe Mode and Safe Mode Benefits


How to enter Safe Mode and Safe Mode Benefits-how to enter Safe Mode and benefit of Safe Mode Safe mode is an option-option start up windows the main function to handle if there is a problem with the system. Windows will run with minimal conditions, only the files and the drivers that are important only in the switch, including also additional software is largely not enabled.

How to go into Safe Mode:

One of the ways that can be used on almost any windows systems including windows Vista is by pressing the F8 key when windows is booting (or when the computer is turned on and begins to perform information Memory/hardware). After that it will perform some boot options menu of the computer.

Explanation of the Windows Options Menu: Advande

1. Safe Mode, this option means that windows will run using only minimal files and drivers as well as software-softwarenya.
2. The Safe Mode with Networking, safe mode like this option coupled with the drivers so that we can make use of a network (Networking)
3. The Safe Mode with Command Prompt, the same as safe mode except that a Command Prompt program/MS-DOS Prompt (cmd. exe) will be active (rather than explorer)
4. Enable Boot Logging, windows will create the Ntbtlog file. txt, when a start up start up information and they will be stored in the file. These files are usually saved in the system root, such as the C drive:
5. Enable VGA Mode. Windows will run with minimal mode display for example 640 × 480 or 800 × 600. Commonly used to check for damage or error [drivers] VGA (graphics display windows).
6. the Last Known Good Configuration, run windows using the registry information that was saved when the last shutdown. Use if we modify the system configuration, or when windows failed to get into the main display.

The Benefits Of Safe Mode:

• Uninstall the previous software that causes the computer to hang, error and so on. Sometimes after you installed a particular program windows are problematic, so if can not uninstall through the regular mode use Safe Mode.
• Disable the application or a specific program. To ease after getting into Safe Mode, it can use the application that can be obtained free Autoruns from SysInternals. This technique can also be used for checking the computer slow loading. If no, Autoruns can type MSCONFIG in the Run menu to run the System Configuration Utility appears, if it is selected through the Startup tab.
• Check the display problems with windows graphics (VGA). When the display windows can be problematic, in check by selecting "Enable VGA Mode", if successful and did not see the problem, it is likely a problem in VGA driver.
• Delete file/virus that could not through the usual fashion. Most antivirus can still run in safe mode, and could try scan through safe mode. Sometimes the virus is not running in safe mode, though many also yg can walk/atif though in Safe Mode.
• Run System Restore If previously enabled, so the condition of the system can be restored to a previous state.
• Run a variety of features from the Control Panel, Administrative tools and so on.

System and the workings of the complete Computer

System and the workings of the complete Computer



System and the workings of the complete Computer-initial concept creation of a computer is as a tool to calculate. The term computer is taken from the latin computare, meaning count, if in the English language to compute, the meaning is the same, namely to calculate.
In general the computer can be defined as electronic tool that works in coordination and integration based on the program, it can receive input which is processed data in the form of a system and issued in the form of information.
To better understand the concept of a computer you could note the organizational structure of the computer along with the following explanation:

1. Input Device (input devices)

Hardware is a computer that serves as a tool to enter data or commands into the computer

2. Output Device (the tool Output)

Is computer hardware which serve to display the output as a result of processing the data. Output can be either hard-copy (paper), soft-copy (to monitor), or in the form of sound.

3. I/o Ports

This section is used to receive or send data to external systems. Input and output equipment above connected via this port.

4. CPU (Central Processing Unit)

The CPU is the brain of the computer system, and operational function has two parts: ALU (Arithmetical Logical Unit) as the central data processor, and CU (Control Unit) as the controller computer work.

5. Memory

Memory is divided into two parts, namely the internal memory and external memory. Internal memory in the form of RAM (Random Access Memory) that serves to keep our sports programs for a while, and the ROM (Read Only Memory) that is a read-only memory and is useful as a provider of information when the computer is first lit.

6. Data Bus

Is the transfer of data between modules in a computer system. Because at a certain time each channel can only take 1 bit of data, then the number of the channel to determine the number of bits that can be transferred at one time. This data bus width determines the performance of the system as a whole. Its nature is bidirectional, meaning that the CPU can read and menirma data via the data bus. Data bus typically consists of 8, 16, 32, or 64 lines parallel.

7. The Address Bus

Used to indicate the location of the source or destination data transfer processes. On this line, the CPU will send the memory address will be written or read. The address bus is typically composed of 16, 20, 24, or 32 lines parallel.

8. Control Bus

Control Bus is used to control the use of and access to the Data and Address buses. Consisting of 4 to 10 parallel lines.

Types of Backup and Recovery as well as the steps

Types of Backup and Recovery as well as the steps


Types of Backup and Recovery as well as the steps are backed up copy the content into other media such as disk: floppy disc, magnetic tape, optical disk, external hard drive, etc.

Types Of Backup:

BackupPenuh (Full Backup)

A full backup is to copy all the data including folders into other media. Therefore, the results of full backups faster and easier while operation restore. However at the time of its creation requires time and a very large room.

BackupPeningkatan (Incremental Backup)

Incremental backups is to copy all of the data that changed since the last time doing a full backup or differential backup. Incremental backups, also called differential backups
Pros:

Requires less time.

If many do incremental backups, then the data in the backup is getting smaller in size.
Backups are faster than full backups and takes place while smaller than required by the full backup.

Pros:

Requires less time.

If many do incremental backups, then the data in the backup is getting smaller in size.
Backups are faster than full backups and takes place while smaller than required by the full backup.

Disadvantages: very long time to restore.

Backup Mirror (Mirror Backups)

Mirror backup is the same as a full backup, but the data is not in the compress or compressed (with format. tar,. zip, or other) and not protect it with a password. It can also be accessed with the menggunakantools like Windows Explorer. Mirror backup is the fastest backup method when compared with the other methods because it copies the data to the media folder and the destination without compacting. But it cause its storage media must be quite large.

How To Make A Back Up:

1. open the "Windows 7 File Recovery" in search in Windows 8

Recovery is an attempt to restore the database to a State considered correct after a failure

Recovery:

This Type Of Recovery:
recovery against the failure of dealers ': unity of the natural program to producers
change/memperbaruhi data on a number of tables.
recovery: recovery media failure against karna media failure by taking back or contains a copy of the database (backups).
recovery against system failure: because of distractions, electrical, hang sisitem disconnected
aliranya

Recovery facilities on DBMS

the mechanism of periodic backups
logging facilities by making tracks on the spot when the transaction takes place and the pda when a database is changed
on-site checkpoint, the latest database update.
Recovery Manager, allow the system to save the reload database becomes more consistent after an error occurs

Recovery techniques

defered update/change yg postponed: changes to the DB will not take place until the transaction is on a pawn in accept (commit). If failure occurred then there will be changes, but in the need to redo operations to prevent the consequences of such failure
immediate updates/changes: changes to the DB will immediately without having to menuggu a deal approved. in case of failure.
shadow paging: using the page shadow imana in process consists of 2 the same table, the other one being a yg laen and the transactions tables in use as a backup when the transaction started to take place both in this same table and during the progress of the transaction table wrote Save all changes to the database tables of the shadow will be in use if an error occurred. upside is not need a REDO or UNDO, kelemahanya makes the occurrence of fragmentation

2 types of techniques in Troubleshooting and Explanation

2 types of techniques in Troubleshooting and Explanation


2 types of techniques in Troubleshooting-Troubleshooting, is a term in the language of the United Kingdom, which refers to a form of the resolution of a problem. Troubleshooting is the sourcing problems systematically so that the problem can be solved. Troubleshooting, sometimes it is the process of removing the problem, and also the process of removal of the cause of a potential problem. Troubleshooting, generally used in a variety of fields, such as in the field of computers, System Administration, and also the field of electronics and electricity.

Techniques in Troubleshooting:

1. Forward Engineering

These techniques are all sorts of problems detected since the beginning of computer assembled and this technique is usually only used by those computer dealers often do the Assembly of the computer. This is only done on detection of a problem in a simple and done before the computer is turned on (electrified). Please refer to the following example:
§ After the computer finishes are assembled, then carried out checks on all the Hardware has been installed, for example, examining the relationship of the Power Supply cable to the power connector on the Motherboard.
§ To ATX casing, we check whether the Power Switch cable is mounted correctly.
§ etc.

2. Backward Engineering

Backward engineering is a technique to detect errors on the computer after the computer is turned on (electrified). The technique more widely used because in general problems in the new computer will arise after the "flying hours" have been many and this is already a reasonable thing. We can take some examples as follows:
§ Floppy Disk that can't be read properly.
§ Computer does not want to light up when the power button on the casing is pressed.
§ etc.

Understanding CD ROM, CD ROM Drive, DVD ROM, DVD ROM Drive Full

Understanding CD ROM, CD ROM Drive, DVD ROM, DVD ROM Drive Full


Understanding CD ROM, CD ROM Drive, DVD ROM, DVD ROM Drive Full - Know your CD-ROM and DVD ROM
Understanding CD ROM, CD ROM Drive, DVD ROM, DVD ROM Drive Full-CD (Compact Disc) and DVD (Digital Video Disc) now commonly used worldwide because it is a reliable standard equipment. The CD can be easily carried and could even to save the data. In General, the sense of CD-ROM (Compact Disc Read Only Memory) is a medium for storing data or other information in very large quantities (more than 600 megabytes). Far greater if we compare it to a floppy disk (1.4 MB). CD ROM can be accessed and read on screen, or printed from any computer that has a CD-ROM player. A CD can store information in various forms, such as: text, images, presentations, slides, audio and video. Then how the CD-ROM was made?

CD ROM history starting in 1983 data storage systems on optical discs were introduced with the release of the
Digital Audio Compact Disc. Since then the optical disc storage technology on developing.

Ingredients The Makers Of CD ROM
CD-ROM are generally made of resin (polycarbonate) and coated surface that is very reflective like aluminum. Information recorded digitally as microscopic pits on a reflective surface. This process is carried out using high-intensity laser. Perforated surface is then coated by a layer of nodes. The information is read using low-intensity laser that illuminates the clear coating while the motor
rotating disc.
The intensity of the laser is changed after hitting the holes are then detected by the terefleksikan and fotosensor which are then converted into digital data. Writing data on a CD-ROM can only be done once. However, this has the advantage of optical disc in terms of mobility. Its small and thin making it easy to carry everywhere.
Compact Disk Read Only Memory, optical storage Media are physically identical to the CD-Audio in was first used as a storing sound recordings. This medium is read using the CD-ROM Drive. Access speed CD-ROM drive is typically measured in units of speed. 1 x speed is equivalent to 150 kBps (kilbyte per second) read speed on the CD Audio device.

Disc Type CD
CD disc that we often see in the market are divided into three namely, CD-ROM, CD-R and CD-RW. Each has its own characteristics.

CD-ROM
CD-ROM disc usually colored silver. The manufacturing process is the way to put a piece of plastic that have been irradiated by the laser beam. Laser beams that will form a sort of pit (pit) micro-sized, which is very small. The holes that will form the contents code row of the form data. Once created the hole, then there can be closed again. Then a layer of plastic that will be wrapped again by the molten plastic which is useful as a protector and reflectors. All of that process is done gradually in a machine prints. Tool mould CD-ROMs resemblance sweet martabak cookie cutter and also making similar analogies like that.
In accordance with its name the ROM (Read Only Memory), the data in the CD-ROM cannot be erased so that
CD-ROM cannot be erased or recorded on CD Writer we have.
The quality of the CD-ROM drive specified by the third layer as in the picture. The lining of the reflectors must be able to reflect the light emitted by the laser beam with the perfect so that information dilapisan data can be read properly. Temporary protective coating should be strong so that the data layer is not damaged because of a scratched or dirty.
The original CD-ROM are generally more durable than pirated CD-ROMs. Because the quality of layers on the original CD-ROM is very powerful and qualified under the standards of reliable quality. But not a possibility there are pirated CD-ROM berkualias, but the price is not cheap.


CD-R
Stands for Compact Disc Recordable. The dish is commonly colored green, but there is a
Blue, red and black. The manufacturing process is virtually the same with CD-ROM, i.e. in a way put a sheet of plastic and lining. The difference is that plastic has not been irradiated by the laser. Then a layer of plastic that will be wrapped again by the molten plastic which is useful as a protector and reflectors. Then when a plastic sheet that will be laser irradiated? The answer later on when we wanted to record it. That's why C-R is called also with CD-Blank because the contents are still empty.
Determine the quality of CD-R also equals quality CD-ROM. But there are to be so extra attention, namely because the recording process is done after CD printed and there are so many CD-R's on sale over the counter, then the quality of the sheet in the CD-R it must match with CD Writernya.

CD-RW DRIVE
CD-RW drive which stands for Compact Disc Rewritable is a type of CD we can content themselves, then we can delete the contents if desired. The price of the CD-RW drive is usually more expensive than CD-R

DVD ROM
Digital Versatile Disc-Read Only Memory. Types of storage media with physical form is similar to the CD-ROM but has a much higher capacity and the ability to save on both sides. DVD-ROM is typically used for storing mutimedia files are large.

CD ROM Drive
Compact Disk Read Only Memory Drive, is a reader of CD ROM on a computer, either in the form of CD programs, movies, songs, etc. Design standard for devices such as the CD-ROM drive is ATA-PI
(Advanced Technology tachment – Packet Interface) that is connected to the IDE interface.

An example of the speed rotation of the CD ROM Drive:
8 x, 16 x, 24 x, 32x, 48 x and 50 x, 52x, 56x

DVD ROM Drive
is a DVD ROM reader devices on the computer, whether in the form of DVD programs, movies, songs, etc. For the moment the speed of rotation of the DVD still revolves around 16 x.

Types of Mouse Based Connectors, buttons and its brand - The Workings Of The Mouse
Types of Mouse Based Connectors, buttons and its brand – basically, the pointer (pointer) known as  "Mouse " can be driven anywhere based on the direction of movement of a small ball inside the mouse. If we open and pulled out a small ball in the back of the mouse, then it would seem the motion controller 2 in it. Both the motion controller can move freely and control the movement of the pointer, which is a unidirectional horizontal (horizontal) and one vertical (top and bottom).
If we simply move the controller horizontal then the pointer will only move horizontally on the screen of a computer monitor. And vice versa if the pointer is moved, then the vertical pointer (pointer) only move vertically only dilayar monitor. If both we move the pointer motion then (pointer) will be diagonal. Well, if the little ball put back, then the ball will touch and move the second the motion controller in accordance with the direction we move the mouse.
In the majority of mouse there are three buttons, but generally only two buttons that function, i.e., the left-most button and the far right. The influence of keystrokes or known by the term "Click" it depends on the object (the region) that we point to. The computer will ignore keystrokes (click) when it is not about the area or object is not important.
Then in the use of the mouse as well we know the term's "Drag " which means shifting or interesting. When we press the most left without releasing it and while he glides, one as a result of these objects move or be moved (copied) into other objects and there is another possibility. The possibilities for this depending on the type of application programs what we run. The mouse connected to the computer with a cable that is present on the mouse. The end of the cable is inserted in the port in computer CPU.

Types of Printer and how it works

Types of Printer and how it works


Types of Printer and how it works - Printer Technology
Types of Printer and how it works-From time to time, printer technology continues to evolve so inevitably for someone who is always in touch with computers and other equipment should continue to follow the developments. Indonesian language printer means the printer (printing tools). The term ' printer ' is often used to refer to the print tool which is connected with the computer. To connect the printer to the computer required a cable connected from the printer to the computer CPU. Currently, the brand
frequently used printer products include Epson, Hewlett Packard (HP), Canon, Lexmark and many more. To know more clearly about the functions, this type of printer and printer work, please read the continuation of this article.

Printer functions
The printer is one of the hardware (the hardware) connected to your computer and have the function to print the caption, image and display more media from computer to paper or similar. The term is known at printer resolution called dpi (dot per inch). It means a large number of points in an area of 1 inch. The higher the resolution it will be getting good prints were produced. Conversely, if lower resolution then the printout will be bad/no good.

Type Of Printer
Dot-Matrix Printers
Dot-Matrix printers are printers that print is still very low resolution. In addition when it is printing, a printer of this type tend to be hard and voice quality for printing the pictures less good because printed image will look like dots that are interconnected. Generally, a kind of dot-matrix printers also have only one color, that color is black. But this time the printer is still widely used because it is famous for ' wayward ' (durable). Another plus, dot-matrix printer Ribbon is much cheaper compared to toner (ink) for inkjet and laserjet printers types.

Inkjet Printer
Inkjet printer print is a tool that already use ink to print and quality for printing color images is pretty good. Number of pages in the print speed of Inkjet printers is not the same, depending on the type of printer brands. But on an inkjet printer, prints a longer drying when compared to laser printers.

Laser Printer
A portion of a shape similar to a laser printer copiers. Print power is also pretty much can reach more than 10 sheets per minute. The print quality of the laser printer is very nice, so much like the original. In addition prints dry fast. But the price of the printer is quite expensive.

Understanding Scaner Scaner Sense and how it works

Understanding Scaner Scaner Sense and how it works 


Understanding Scaner Scaner Sense and how it works - Scanner is an electronic device that functions similar to copiers. Results can be directly copy machines you see on the paper while the scanner results are displayed on a computer monitor screen first then can be changed and modified so that the look and the result be nice which can then be saved as a text file, documents and images.
Scanner assortment of shapes and sizes, some the size of a magnitude with paper folio there also are the size of a postcard, even the newest, the shape of the newly launched pen by WizCom Technologies Inc. company. the pen-sized Scanners can store up to 1,000 pages of printed text and then transfer them to a personal computer (PC). Pen-sized scanners called Quicklink. Pen scanner measures six inches long and weighs about three ounces. The scanner according to the WizCom may randomly does its job faster than the scanner is flat
The data have been taken with a scanner can put directly to all computer applications that recognize the ASCII text. At this point many once scanners are circulating in the world with various brands, among which the scanner output of Canon, Hewlett Packard (HP), UMAX, EPSON and many more.
The difference of each scanners from various brands lies in the use of technology and resolution. The use of technology such as the use of digital buttons and lighting techniques.

How to work the Scanner:
When you depress the mouse button to start Scanning, what happens is:
Keystrokes mouse from the computer controlling the speed of the machine moves the scanner. Machine located in the scanner control unit delivery to process scanning.
The scanning unit then put the pengiiman process to the place or the appropriate line to directly initiate scanning.
Flame lights seen in the scanning activity indicates that the Scanner has been started. After the flame lights already does not exist, it means the scan process is finished and the results can be seen on the monitor screen.
If the result or the display of text/image want changed, we can change it by using the software application. For example with photoshop, Adobe and others. pot is scanned.

There are two kinds of differences in the scanner checks the drawings are:
The scanner can only one time to scan the color and keep all colors at that time only. Scanners that can direct three times used for storing some colors. The colors are red, green and blue.
Scaner called first faster than the latter, but become less fine if used for color reproduction. Most scanners run at 1-bits (binary digits/numbers in binary), 8-bit (256 colors), and 24 bit (more than 16 million colors). Well, when we need a very good results then dianjurtkan using a scanner with a large bit in order to make the resolution more colors and Nice.
