Computer for beginners

Image
  It seems like you're looking for information related to computers for beginners. Here's a basic overview of key concepts that might be helpful: 1. What is a Computer? A computer is an electronic device that can process and store information. It consists of hardware components (physical parts) and software (programs and applications). 2. Hardware Components: Central Processing Unit (CPU) : The brain of the computer that performs calculations and executes instructions. Memory (RAM) : Temporary storage that the computer uses to run programs and open files. Storage (Hard Drive/SSD) : Permanent storage for files, programs, and the operating system. Motherboard : The main circuit board that connects all components. Monitor : Displays visual output from the computer. Keyboard and Mouse : Input devices used to interact with the computer. Speakers : Output devices that produce sound. Ports : Connections for peripherals like USB drives, printers, and external devices. 3. Software: Ope...

View your computer information

You can view a summary of important information about your computer by opening system in control panel. You can see basic hardware information such as your computer's name and which edition of windows your computer has running  Software  you can change important system setting by clicking the links in the left pane of system. If you want to know about this just follow these- Open system by clicking the Start button > Control panel > System and maintenance > System.

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.

How to make a hidden files?

Image
It is too easy for everyone. You can create it easily. Just follow this rules,  1. At first create a new folder 2. Then go to the  properties 3. Click on the Change icon button 4. Select the hidden icon 5. Then press OK and then apply and OK again. 6. After hidden your files then you have need to rename it and then not save the files name just Press alt+0160  7. After doing that you can make it easily. N.B: Where you will save that file in there if you can not find that file then press F5. You will find that easily.

Win-Win Spiral Model

Image
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 e...

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 develop...

Software Crisis.

Image
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...

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 projecti...

What is spyware

Image
It is one of the big program in the computer. Spyware collect a lot of different type of information about a user. Spyware is a type of program that watches what users do with their computer and sends that information over the internet. More malicious version can try to record what a user types to try to intercept password and credit card numbers. Other versions simply pop up advertisements. It is not a illegal software, No one can prove it as a illegal software. Spyware is one kinds of Advertising supported software. It is a way to sharewares to make money from a product. Other than by selling it to the users. In this way you do not have to pay for your software and the developers are still getting paid. It is one kinds of great software who use this software his/her computer must be in safe position. It can safe your computer with block and detected your computer 's wrong items.

Update your Computer

A  computer   is one of the important tools for everyone in this world. Sometime it is looking so old and its functions are also old. If you want to update your  computer  , please follow these rules. If your hard drives lacks free space. Then you have need to upgrade to a larger drive.  Check how much space you have left by right clicking the hard drive icon to use the "C" drive and selecting "Properties. " After selecting the properties you will get information about that folder. If your  computer   is running slow, you may need to upgrade your processor or the RAM.  If your system only has on CD drive, consider to replacing it with a DVD drive.  If you watch videos and listen to music or play any games on your  computer   , consider upgrading your video or audio cards. If you want to upgrading your software simply insert the disc and follow the installation rules.  If you're installing new h...
