Partition The Hard Drive Of Your Computer.


Partition the hard drive is one way that can be used to share the hard disk into multiple drives are recognized in all the operating system but with adjustments to the file system used. Partitioning is done so that there is no separation between files which is always running and files that are not always running. This was done because of the possibility of a single computer; there are two different operating systems. If you use a computer operating system will be installed based on open source then it should be done when the partition is the operating system will be installed. If you are Microsoft operating system users, it helps you use the latest systems, window 7. Because one of the advantages of Windows 7, is able to create disk partitions safely without using additional software eg Norton partition magic, partition manager ranish, Eazeus Partition Manager and there are still others. Here's how to partition and format the hard drive in Windows 7
*    Click the Start
*    Right click on Computer
*    Click Manage, click Disk Management continued with
*    In the middle of the bottom of the window please select the drive that has not been partitioned.
*    Right-click on the white box below the thick black line and select New Simple Volume
Click Next, it would seem clear that the hard drive capacity.
*    Then divide this hard drive into two partitions so I have to split the 2 hard drive capacity is the maximum value in Simple volume size in MB, for example 300/2 = 150 000. After that click next.
*    Next again, and click Finish

If there is a problem that caused some of the definitions are not detected while accessing the windows explorer. This is usually caused by several factors, such as the partition is less than perfect, hard disk bad sectors, partition software bug, compatibilities file system, etc. One of the free software that can be used to repair a disk partition that is hidden is a Partition Find & Mount.

Create a dummy files

Here are five ways to create a file that looks legitimate but is actually a dummy files. But why would you want to create a dummy files? Here are five reason for that:
1. Test hard drives - Detected bad sector on your hard drive by filling up free space with a dummy files.
2. Securely delete files - A deleted files can be can be recovered but by overwriting the free space with a dummy files will make it unrecoverable. 
3. Secure flash drive - Make your flash drive read only by filling up empty spaces and prevent virus infections. 
4. Test network speeds - While there are free utilities available to test network speeds, You can do so with a dummy files too.
5. Dummy files can also help you escape a deadline you have got to prepare a report or finish your by putting the blame on your faulty computer.

Win-Win Spiral Model

Boehm and Ross (1989) extended the original spiral model by including considerations related to stakeholders. The win-win spiral model uses the theory W management approach, which requires that for a project to be a success, the system’s key stakeholders must all be winners. The way to achieve this win-win condition is to use the negotiation based approach to define a number of additional steps of the normal spiral development cycle. The additional steps are the following:
• Identify next-level stakeholders.
• Identify stakeholders’ win conditions.
• Reconcile win conditions.
• Establish next-level objectives, constraints, and alternatives.
• Evaluate product and process alternatives.
• Resolve risks.
• Define the next-level of product and process, including partitions.
• Validate product and process definitions.
• Review and commit.
The advantages from a win-win spiral model is the collaborative involvement of stakeholders that results in less rework and maintenance, early exploration of alternative architecture plans, faster development, and greater stakeholder satisfaction upfront.

Characteristics of software

software is a logical rather than a physical system element. Therefore, software has characteristics that are considerably different from those of hardware. Some of the major differences are the following:
1.software is developed or engineered, it is not manufactured.
• The concept of raw material is non existent here. It is better visualised as a process, rather than a product.
• The human element is extremely high in software development, compared to manufacturing.
• The development productivity is highly uncertain, even with standard products, varying greatly with skill of the developers.
• The development tools, techniques, standards, and procedures vary widely across and within an organisation.
• Quality problems in software development are very different from those in manufacturing. Whereas the manufacturing quality characteristics can be objectively specified and easily measured, those in the software engineering environment are rather elusive.
2. Software development presents a job shop environment.
• Here each product is custom-built and hence unique.
• It cannot be assembled from existing components.
• All the complexities of a job shop are present here.
• Human skill, the most important element in a job shop, is also the most important element in software development.
3. Time and effort for software development are hard to estimate.
• Interesting work gets done at the expense of dull work, and documentation, being a dull work, gets the least priority.
• Doing the job in a clever way tends to be a more important consideration than getting it done adequately, on time, and at reasonable cost.
• Programmers tend to be optimistic, not realistic, and their time estimates for task completion reflect this tendency.
• Programmers have trouble communicating.
4. User requirements are often not conceived well enough; therefore a piece of software undergoes many modifications before it is implemented satisfactorily.
5. There are virtually no objective standards or measures by which to evaluate the progress of software development.
6. Testing a software is extremely difficult, because even a modest-sized program can contain enough executable paths so that the process of testing each path though the program can be prohibitively expensive.
7. Software does not wear out.
• Software normally does not lose its functionality with use.
• It may lose its functionality in time, however, as the user requirements change.
• When defects are encountered, they are removed by rewriting the relevant code, not by replacing it with available code. That means that the concept of replacing the defective code by spare code is very unusual in software development.
• When defects are removed, there is likelihood that new defects are introduced.
8. Hardware has physical models to use in evaluating design decisions. Software design evaluation, on the other hand, rests on judgment and intuition.
9. Hardware, because of its physical limitations, has practical bound on complexity because every hardware design must be realised as a physical implementation. Software, on the other hand, can be highly complex while still conforming to almost any set of needs.
10. There are major differences between the management of hardware and software projects. Traditional controls for hardware projects may be counterproductive in software projects. For example, reporting percent completed in terms of Lines of Code can be highly misleading. It is now time to give a few definitions. The next section does this.

Software Crisis.


During the late 1960s and 1970s, there was an outcry over an impending software crisis. The symptoms of such a crisis surfaced then and are present even today. The symptoms are the following:
1. Software cost has shown a rising trend, outstripping the hardware cost. Boehm (1976, 1981) indicated that since the fifties, the percentage of total cost of computation attributable to hardware has dramatically reduced and that attributable to software has correspondingly increased. Whereas software cost was only a little over 20% in the 1950’s, it was nearly 60% in the 1970’s, and about 80% in the 1980’s. Today, the computer system that we buy as ‘hardware’ has generally cost the vendor about three times as much for the software as it has for the hardware (Pressman 1992).
2. Software maintenance cost has been rising and has surpassed the development cost. Boehm (1981) has shown that the bulk of the software cost is due to its maintenance rather than its development.
3. Software is almost always delivered late and exceeds the budgeted cost, indicating time and
cost overruns.
4. It lacks transparency and is difficult to maintain.
5. Software quality is often less than adequate.
6. It often does not satisfy the customers.
7. Productivity of software people has not kept pace with the demand of their services.
8. Progress on software development is difficult to measure.
9. Very little real-world data is available on the software development process. Therefore, it has not been possible to set realistic standards.
10. How the persons work during the software development has not been properly understood. One of the earliest works that explained to a great extent the causes of software crisis is by Brooks (1972). We shall get in the next section a glimpse of the work of Brooks.

What is Software?


We are living in an information society where most people are engaged in activities connected with either producing or collecting data, or or gangling, processing and storing data, and retrieving and disseminating stored information, or using such information for decision making. Great developments have taken place in computer  hardware technology, but the key to make this technology useful to humans lies with the software technology. In recent years software industry is exhibiting the highest growth rate throughout the world, India being no exception. Software is the general term for information that's recorded onto some kind of medium. For example, when you go to the video store and rent or buy a tape or DVD, what you're really getting is the software that's stored on that tape or disk. Your VCR or DVD player are hardware devices that are capable of reading the software from a tape or disk and projecting it onto your TV screen, in the form of a movie. Your  computer  is a hardware device that reads software too. Most of the software on your computer  comes in the form of programs. A program consists of instructions that tell the  computer  what to do, how to behave. Just as there are thousands of albums you can buy on CD for your stereo, and thousands of movies you can buy to play on your VCR or DVD player, there are thousands of programs that you can buy to run on your  computer . When you buy a computer, you don't automatically get every program produced by every software company in the world. You usually get some programs. For example, when you buy a computer it will probably have an operating system already installed on it. If you do purchase a specific program, it would be to perform some specific task. For example, you might use a graphics program to touch up photos, or you might use a word processing program to write text. You're using your Web browser program right now to read this text. Just as there are umpteen different brands of toothpaste, there are umpteen different brands of word processing programs, graphics programs, and Web browsers.

How to choose the best Hard drive?


Find out the various type of hard drive and which type is most suitable for your system. A hard drive is a storage place where you install and store all your programs and data. Generally, the bigger the capacity, the more data you can store. The main difference between the hard drive and  computer  RAM is that computer RAM contains only volatile data, which means all the data is lost when the power is switched off while hard drive can be used to store permanent data. These solid state drives are the ones to beat in the SSD world at the moment. The last generation SSDs were capable of 280/270MB/s but the new drives are capable of 550-500MB/s, in other words, double the speed of last generation. This equates to sub -10 second Windows load times and also sub-5 second game load times. That's blazingly fast performance with no bottleneck. Expected data speeds of 1Gb/s+ once a RAID array is set up.

Turion X2 Ultra

Turion X2 Ultra is the first processor family from AMD solely for the mobile platform, based on the Athlon 64 architecture with some specific architectural enhancements similar to current Phenom processors aimed at lower power consumption and longer battery life. The Turion Ultra processor was released as part of the Puma mobile platform in June 2008.
The Turion X2 Ultra is a dual-core processor to be fabricated on 65 NM technology using 300 mm SOI wafers. It will support DDR2-800 SO-Dim Ms and features a DRAM preference to improve performance and a mobile-enhanced north bridge. Each processor core comes with 1 MiB L2 cache for a total of 2 MiB L2 cache for the entire processor. This is double the L2 cache found on the current Turion 64 X2 processor. Clock rates range from 2.0 GHz to 2.4 GHz, and thermal design power will range from 32 watts to 35 watts.
The Turion X2 Ultra processor, unlike earlier Turion, implements three voltage planes: one for the north bridge and one for each core. This, along with multiple phase-locked loops, allows one core to alter its voltage and operating frequency independently of the other core, and independently of the North Bridge. Indeed, in a matter of microseconds, the processor can switch to one of 8 frequency levels and one of 5 voltage levels. By adjusting frequency and voltage during use, the processor can adapt to different workloads and help reduce power consumption. It can operate as low as 250 MHz to conserve power during light use.
Additionally, the processor features deep sleep state C3, deeper sleep state C4, and Hyper Transport 3.0 up to 2.6 GHz, or up to 41.6 GB/s bandwidth per link at 16-bit link width and dynamic scaling of HT link width down to 0-bit in both directions from and to the chipset for four different usage scenarios. It also implements multiple on-die thermal sensors through integrated SMBUS interface with additional MEMHOT signal sent from embedded controller to the processor, and reduces memory temperature.
The Turion X2 Ultra processor uses the same socket S1 as its predecessor, Turion 64 X2, but the pin out is different. It is designed to work with the RS780M chip set.
Given the above enhancements on the architecture, the cores were minimally modified and are based on the K8 instead of the K10 micro architecture. AMD Fellow Maurice Stein man has said the cores are almost transistor-for-transistor identical to those found in the 65 NM Turion 64 X2 processors.
