is a junk file junk files. these files are not useful. for example, temporary files, old files and recent file. all files must be cleaned as if the pile will be spending your hard disk space. consequently, the performance of hard disk is slow so that the effect on the performance of the computer itself. you leave at least 15% of the total capacity of your hard disk.
junk files do not appear out of nowhere. when you open the application program, the program automatically create temporary files, no windows except itself. temporary file is deleted by itself automatically when the program closes. however, sometimes the temporary file with extension. TMP still left in the hard disk and not deleted. long the temporary file will fill your hard disk.
you can see the temporary files by default in place in the directory C: \ windows \ temp. besides, you can see it through MS-DOS prompt with the command set picking. in windows 98 there is a tool that can automatically delete temporary files with disk cleanup. on Windows 98, you must have installed the microsoft plus! 98 because of the features of the Windows 98 disk cleanup usual incomplete.
to perform disk cleanup:
- select start | programs | accesories | system tools | disk cleanup.
- select the drive where you will do a disk cleanup, click ok to run the executable.
in addition to the above method, there is no way to delete automatically when windows is started up, is to create a batch file. open the autoexec.bat file contained in the root-directory C: with notepad. in the last line, type the command: Del C: \ windows \ temp \ *. TMP. then, save the file.
bin files with extension TMP is not just, there's more like BAK, OLD, SIK, CHK, and much more. bin file is not found only in the temp folder, but scattered across your hard disk and hard to find even to remove them. you can get around by clicking the start menu | fine | files and folders. named in the column, type the extension *. bak; *. chk; *. tmp; *. old; *. sik. look in the contents column on mycomputer, then you click find now.
after the search is complete, click on one file, then delete to delete. This method only removes one by one file. to select all files, press the key combination Shift + A, then delete. to search garbage files, click the file menu | save the search. after that, will appear a new icon files named @. bak; @. tmp; @. old;. the more you often do cleaning junk files, it will affect the performance of your computer's hard disk.
in addition to using this method, you can delete junk files using utility software. one of them is this mechanic.utilitas mempunyaibanyak system to optimize the features for windows. one of them, the ability to find and remove junk files. you can download from the internet at sites www.lolo.com. The program is shareware. within 30 days, the program will be inactive by itself even if you reinstall. to get its full version, you have to register or pay.
to run it, first do the installation. after installation, the steps:
- select the start menu | system mechanic | start system mechanic, then will appear as shown below.
- select the menu find and remove junk and obsolete files. to eliminate junk files, you first select the drive you are going to clean it. Click scan to begin the search.
- after the file is found, click remove all entries to remove. click yes and exit to exit.
before you practice, there is some hardware that you need to prepare, including :
- UTP (Unshielded Twisted Pair). UTP cables are frequently used categori 5 UTP cable (UTP Cat-5). why? for Cat-5 UTP cable support data transfer up to 100 Mbps. This cable consists of 8 small that have different colors. The cable color is orange, orange and white, blue, white, green, green, white, brown, white chocolate.
- the second is the RJ-45 jack. jack is similar to a home telephone jack. only the larger size. RJ-45 jack consists of 8 pins, according to the number of UTP cables
- crimping tool or crimping pliers. hardware that is similar to a pair of pliers. however, unlike its function pliers in general. crimping tool is useful to clip the cable to the RJ-45 jack.
all the above hardware can be found at most computer stores. the price is not too expensive.
UTP cable straight type
I will now discuss how to install. The first is how to install UTP cable straight type. for it to do the following steps:
- peeled end of the wire about 1 cm, so that the small wires that are inside look.
- attach the cables and straightens. then collated and the trim on the white color is orange, orange, green, white, blue, white blue, green, white and chocolate brown. after it cut the edges so that the average of each other.
- after a structured cabling, RJ-45 jack grab. as I said earlier this jack consists of 8 pins. pin 1 of the jack is located adalahpin the left if your facing the pin position. sequential to the right is the jack 2, 3, 4, and so on.
- then insert the wires into the RJ-45 jack in the order was as follows:
- Orange-white on pin 1
- Orange to pin 2
- Green-white on pin 3
- Blue on pin 4
- Blue and white on pin 5
- Green on pin 6
- White chocolate on pin 7
- Brown on pin 8
insert the cable until the tip is stuck in the jack.
- insert the RJ-45 jack which is mounted with the cable before crimping pliers in your mouth corresponding to the pin RJ-45 jack in the mouth pliers. now had a jack flops tangcrimping pin sticking up all over the wiring. usually if the pin is stuck jack will give voice "click".
now you've finished installing the RJ-45 jack on the end of the first cable. to the second end of the cable, the steps are the same as the first one end of the cable installation. to repeat the earlier steps to install the RJ-45 jack on the end of the second cable.
UTP cable straight type arrangement you can see in the picture below:

UTP cable type cross
how to install UTP cable straight type I described earlier. Now I will discuss about how to install the type of cross UTP cable. UTP cabling to cross almost the same type by placing a straight UTP cable types. about the same as before the technical installation. the difference is the color sequence of wires at the second end of the cable. The first end of the cable, the cable structure with UTP cable straight type arrangement are:
- Orange to pin 1
- Orange-white on pin 2
- Green on pin 3
- Blue on pin 4
- Blue and white on pin 5
- Green-white on pin 6
- White chocolate on pin 7
- Brown on pin 8
to the second end of the cable, the color arrangement different from the first end. As for the arrangement of the colors is:
- Green-white on pin 1
- Green on pin 2
- Orange-white on pin 3
- Blue on pin 4
- Blue and white on pin 5
- Orange to pin 6
- White chocolate on pin 7
- Brown on pin 8
composition had wiring you can see in the picture below

the end result will cross UTP cable types like this:

the conclusion is if you plug in the UTP straight type arrangement of colors on both ends of the cable is the same. whereas UTP installation way cross type, color composition different from the first end of the cable end of the second cable.
tutorial how to install this type of straight UTP cable and cross type.
