It is also utility software which is made by Microsoft window operating system to remove unnecessary item from the window registry. Unwanted file no longer in a use so it has been completely remove from system by cleaning. Some of the file is left by registry cleaner that has no been uninstalled from the system. Registry cleaner is scan the registry and left only unwanted data in order to repair or delete. It may improve the performance of computer by using registry cleaner; if error is occur while processing computer registry helped to resolve the problem. Registry cleaner search the file error on File types, Fonts, Startup, Database driver, Application paths etc and it immediately solves the problem. Some of the registry cleaner can not solves the problem found.
I use Tuneup registry cleaner utility software which used to remove unnecessary error file or data from system and also clean it. When user click on complete scan button and press on next button and automatically it scan the system for e.g. application, font, history installation program etc. Complete analysis we should click on show problem. It shows the summary problem. After do click on start cleaning and click to continue the cleaning of your system and it complete cleaning.

Disk partitioners is a process of dividing the storage space of hard disk drive in to individual file is known as partition. It can divide separate drive in to multiple logical or primary drive each its own data system. A program editor ca be edit delete or modify the logical drive. By parting the drive into many the user can store the data in different drive. So user feels easy to use the computer. Easy to control if we make many drive, kept the file in private .proper care of make the size of the partition needed to change the size depends upon install on the drive.
When we click on the disk management, it shows different drives like C:\,D:\,E:\,F:\ etc. Right click on drive and get option like change drive path, make partition as active. At first we have to active drive and format drive. Drive should to delete because to make drive free space on the hard disk. We can create different drive as recommended by the user. New drive is completed. if drive can be separated only primary drive acne partition but not system drive i.e. C:\.

Disk cleaner

Disk cleaner detect the data that are unused to computer operation. When the hard disk is full the user decided to clean the files .Cleaner is shareware and freeware software which optimize privacy and cleaning tools.
Disk cleaner clean the unnecessary file from the system allowing window to run very faster and makes space on disk. Disk cleaner can be used in online activities like as our internet histories for example are:-

• internet explorer
It contain temporary file, history etc.
• window explorer
Document, run etc are the window explorer unnecessary file.
• System
It contains file data such as empty recycle bin, temporary file, memory dump etc.
I used Microsoft window vista ccleaner utility program which helped to clean unnecessary file from the system. when I click on analyze button it search the details files to be delete from computer and click on run cleaner then it clean file like application data, cookies, temp etc

Introduction:-
GPRS means general packet radio service. GPRS is a new non voice value added service that provides information to be sent and receive to the mobile network. Circuit switched data and short message service is supplement nowadays. GPRS (Global positioning system) which is uses in mobile. Mobile is progressing from second generation mobile network to 3rd generation of network that able to handle max speed multimedia traffic. It is transfer to 3rd generation (UMTS) is far from clear GPRS is evolution of the GSM standard and sometime called GSM ++.so it is second generation telephony standard that provides a transition to 3rd generation. It is classified as 2,5G. GPRS extended the architecture of GSM which allow to transfers packet data to the theoretical data rates on the order of 171.2kbit/s.the user can remain connected at paying no access to particular internet using IP protocol. It appreciated new features or technology but not available with the GSM standard which is categorized into following classes:-
· Point to point service
· Point to multiple point service
· Short message service (sms).
The video conferencing and on-line shopping will be as smoothly talking on the mobile phone and we are work at home or traveling. Mobile phone is delivering the information to the customer or people of sending and receiving video, image etc.

Feature of GPRS:-
The highest speed of up to 171.2kilobits GPRS by using all eight times slots at the same time. Three times faster data transmission speeds is possible nowadays, fixed telecommunication network and ten times as faster as current circuit switched information service on GSM network. When data is transmitted quality mobile network than sms. It may be less costly mobile data servicing. No dial up modem is required to connection of GPRS. Remote credit card authorization where it would be not accepted to kept the customer waiting for even thirty second more extra.

Importance:-
International industries have had in approving the entire necessary standard has led to delay to development of 3G wireless system. It was delay because of GPRS being introduced an intermediate step to efficiency transferred max-speed data over on GSM network infrastructures. GPRS provides to mobile uses faster data speed and especially suitable to the bur sty internet and intranet traffic. It make chapter and faster to be uses of GPRS. It provides end to end IP connectivity that is connected to LAN. GPRS provides instantaneous connection set up- and allow charging on the basic of information transmitted then connection time. It supports 14.4kbps to 115 kbps.

BLUETOOTH

Introduction:-
A proposed radio frequency specification that many portable devices will use for short-range wireless communication is known as Bluetooth. Bluetooth device such as laptop computer, handheld computer, pagers, cellular telephones, fax machines, and printers are widely communicated with each others pc to internet. To use Bluetooth communication each device must have chip and be within a specific range (about 10 meter to 100meter). Company is observed to expect Bluetooth to be implement in billion of devices up to date in 2005.Bluetooth are published by company consortium called the Bluetooth SIG (special Interest group).It is developed by same engineering at Ericsson. Bluetooth is a most popular technology that enables short-range wireless communication between varieties of electronic devices. it allow devices to talk wirelessly with one to another, Intel, nokia, IBM and Toshiba joined erosion as the founding members of SIG, and more than 8000 companies have signed on since Bluetooth specification and logo, manufacture must be member of SIG company which devices must meet outlined qualifications. Bluetooth wireless devices are used world wide which is communicate with one another device. Bluetooth provide short-range wireless capacity. If we using the 2.4GHZ band available in universe for on licensed low power uses 2 Bluetooth devices within 10m of each other can be share up to 720kbps of capacity. Bluetooth is support audio; graphics are transferring one device to another device. Bluetooth are used in these devices like telephones, headset, cordless, none stereos, cellophane and others devices. Bluetooth wireless specification gets it name from Harold blatant (it transferred to Bluetooth) 10th-century Danish kings who use diplomacy to negotiate a trace between two feuding factors. Today’s world is at the 21st century’s Bluetooth become popular to leading transferring data. The some of the example are mobile phone, headset, USB, en drive keyboard mouse, laptop, phone, and pod etc.

Importance:-
People have been made great advancement in technology. Technology has been improved in the world day by day. After the invention of Bluetooth technology other technology are looking for lunch. When the Bluetooth software begins to developed and famous feature provides in mobile phones. With the helped of Bluetooth many application are made. It includes application software data transmission software for communication for games. We can find more application free of cost while using the normal changes some of the software has annual subscription fees. Bluetooth software are used to transferring the data or file from one phones to another phones. Data can be transfer when other Bluetooth is enabling in the phones or other devices. Picture is transfer easily or faster than others. When Bluetooth is enable we can print out the data such as types of data is transfer is possible with the help of software. We can connected internet by using device which connection with the laptop and provide both devices Bluetooth must be enable and synchronized by via Bluetooth.

Strength:-
Bluetooth has low range of 10meter and information transfer rates up to 3mb (375 kilobytes) per second; Bluetooth technology was suitable for transmitting file like text document, picture, audio, and video.3mb can be access the video and higher quality picture. After 3.0 are introducing this will be change .10mbps seed is required to handle this video, TV signal.

Security issue:-
Bluetooth can operate three security models.
· Mode1 is not security.
· Model 2 serve security at the service level and the channel is build.
· Model 3 provides security at the lime level, before the cannel is built.
It is uses the Bluetooth address to recognize a particular thing and log that transaction when that is can create privacy concerns. The pin number is fist give priority.

The most popular utility program are given below:-

1. Disk scanner/checker

Disk scanner also called disk checker. Disk checker is a utility that determine the physical and logical error on the hard disk, it solve the problem. It scan the hard disk drive to find the corrupted file and correct the error then working capacity will be increase in operating hard disk. It checks health of the hard disk. Problem is occur due to damage of parts, scratch on the disk like physically .Disk scanner is a maintained program that is install on the Microsoft operating system. It performs the task to increase the working capacity of computer. In window 98 have two disk scanner utilities and scan disk which determine the error and resolved the problem by disk cleanup. It search temporary data and removed the data.

I used ADRC hard disk checker. At first choose drive that should be scan and click on export button. Disk checker provide information like drive size, file system, sector, current sector, transfer rate, etc. to user. It also provides information about statistics.
