Computer is a sum of two parts. One is hardware and the other is software. CPU is the hardware part. It is a sum of different type’s part such as hard disk, ram, motherboard, power supply, optical drives etc. There are some extra parts like keyboard, monitor, mouse etc. Software part is the operating system of computer. Computer has different operating system like Mack, Windows, and Linux etc. Both of these parts play a prominent role in enabling the computer to do works faster and swifter. The whole thing is not work all time. Some time it needs proper computer repair and support.

Problems are common. This world is full of problems. Electronic tools, devices face different technical, internal, external problems. Computer repair these problems create a blockage to their work. Computer is a electronic device. It faces different problems. Problems of computer can be divided into two divisions. One is hardware related and the other is software related. Both of the problems are severe. Both of them affect the computer so badly. Hardware related problems consist of the problems of different parts of the computer. Hard disk may also be able to get damage by the virus.

This crushes the important data from the hard disk and often damage of it. Ram, motherboard also faces this problem. Optical drives face electric circuit problems. They don’t get sufficient electricity due to this problem and become unable to work. Monitor, power supply, mouse, keyboard also face electric problems. Software related problem is basically the problem of operating interface, virus attack etc. Operating system gets hampered due to the want of proper installation of the operating system. Virus attack is too much dangerous. It can ruin the whole computer interface. Virus is a freewill program which is so much strong to affect the computers interface easily. It can be spread from computer to computer through unsecured data sharing, unsecured synchronization and unsecured internet browsing. These problems affect computer and hampers it badly.

Electronically damage is common to all electronic devices. Damaged devices need proper repair. Repair is a process by which a damaged device’s condition is improved to normal. Damaged computer also needs proper repair. Computer repair is done by solving the problems or replacing the affected and damaged parts. This repair is done by a skillful technician who knows the problem and solve of it. Nowadays as the IT world is improving, many companies are establishing in local, national and international phases that provide

Computer support and repair service is necessary in daily life. Many problems are found in daily or gradually as a whole. The technicians are introduced with the computer problems no for one day. So we have to consult with the expert one to handle the problem wisely. Otherwise there is a chance of damage of the software and other hardware of the computer.

It’s utterly frustrating that my computer is running very slow. Admit it – when you first bought your computer, it was in crisp condition. The computer delivered all the requirements stated on the specification. You could work with it efficiently and not run into any problems. Now, a very slow computer is affecting productivity negatively. It takes forever to open a simple application. There are many times when the screen suddenly freezes or shows the dreadful Blue Screen of Death. It’s very taxing to keep on restarting the system. Despite using different operating systems already, it still ends up that way. These are just some of the problems that occur when my computer is running very slow.There are many factors behind a slow-running computer: viruses, spyware, low hard disk memory, hard drive fragmentation, registry problems, etc. The moment the computer acts up, check the source of the problem and act on it immediately. Addressing computer problems in their early stages is better than waiting for the problem to escalate.One simple tip you should follow is to refrain from opening multiple programs at the same time, especially if the program or software consumes a lot of RAM. All the programs that you use in your computer rely on RAM memory. If you want to play games, play music, and surf the web at the same time, you need to increase your RAM.Viruses and spyware can highly affect the speed of your computer. Computers that normally work fine but suddenly slow down are usually affected by a nasty virus or spyware. Virus and spyware steal your computer’s resources, explaining the sudden dip in speed. Be wary of the malicious elements in your computer because they can slow down your computer and destroy your files and folders. My computer is running very slow because it is susceptible to viruses and spyware, thanks to the hours spent downloading files off the Internet. Install a reliable anti-virus and anti-spyware and regularly use them to scan for suspicious culprits in your computer. Keep your anti-virus and anti-spyware software updated so that they can detect the new culprits.When my computer is running very slow, checking the hard drives sometimes help in determining the problem. The hard drive is a storage place for files from your computer. One of the signs is that your hard drive is going beyond 90% storage capacity causing your computer to slow down. Remember, you have to maintain at least 10% free space to ensure that the computer can still run at the desired speed. If you can’t bring yourself to delete files and folders, you can transfer them to an external hard drive or burn them in a CD.One decade ago, defragmentation was the easiest way to rehabilitate a fragmented hard drive. Although defragmentation is an old way of solving computer speed problems, it’s still needed once in a while when files get fragmented badly. Defragmentation will ensure that the files are fragmented efficiently.Lastly, many people should know that many computer speed problems can be attributed to a problematic registry. The registry is where your computer saves its settings and preferences that are required for the computer to function well. When my computer is running slow, seeking the help of a registry cleaner often helps.

Ever wondered what using an operating system other than Windows would be like?  Well, there are options!  Most people don’t realize they can install a completely different operating system on their computer.  They trudge along in misery using Windows XP, while they could be using a newer, faster operating system that does everything Windows does and more.

So what is this other option and how much does it cost?

Linux.  And it’s free.

Free?  Well, you say, if it’s free it probably isn’t that great.  You’d be surprised just how polished and fast it runs, even on old hardware.

So where can I get Linux?  You can download it from a number of places.  Here is a link to the Ubuntu Linux OS downloads page.  Ubuntu is one of the better Linux “flavors”.  Yes, there are a bunch of different Linux “distros” to choose from.  Some are made for specialized applications, like audio production, or for use on older hardware.  Others, like Ubuntu, are for end users looking for a nice desktop OS.

Once downloaded, you’ll need to install it onto your computer.  This is where things get tricky and most people will hit snags here.  First thing to remember is don’t do any harm to your current Windows setup.  The best bet is to install Linux onto a separate hard disk, or onto a flash drive for testing purposes.  If you aren’t too technically savvy, then your best bet is to hook into a local Linux user group, a group of Linux fanatics in your area, who’d probably love to assist you.  Do a search for a linux user group in your area here.

Once installed, where do I go for support?  Again, this is where Linux shines.  Rather than calling Microsoft support and getting some person sitting in a call center in another country reading off of a script, you can tap into the community of Linux users for help.  They are usually a very friendly bunch, willing to help you make the jump to Linux.  In the past, Linux had a reputation for users who were a little rude towards new users, but lately things are changing and the Ubuntu user forums are especially friendly to new users.  

The most important thing is don’t give up when you hit a snag.  Once you “get it”, Linux is a wonderful, powerful alternative to Windows.

The Linux system is one of the most used operating systems in the world. It is an open source operating system that is much more secure than other operating systems. It is also very economical as it can be set up even with obsolete hardware components such as i386 or i486 processor. The Linux system also provides you the freedom to administer your system by taking care of the look & feel and also the applications that need to be installed, etc.

However, at times the Linux system gets corrupted because of various reasons such as corrupt file system, power surges, human errors, virus infections, etc. In such cases, you should take appropriate measures to overcome this issue. However, if you are unable to do so then you should use a third-party Linux data recovery software to perform Linux recovery.

Consider a scenario wherein you have a Linux 4 system, which you have restarted. But the system fails to boot and an error message is displayed, that is:

“ext2fs partition type 0×83. …. ext3-fs: journal inode is deleted…. mount: error 22 mounting ext3 error 2 mounting name switchroot: mountfailed:22 umount/initrd/dev failed:2 kernal panic – not syncing”

Cause:
The most possible cause of this error message is that the hard disk has crashed. Some bad blocks must have occurred in the inode table making the file system unrecoverable.

Resolution:
To resolve this issue, you should try the following methods:

• Boot the system from the disaster recovery boot media or installation media and run e2fsk on the damaged file system.
• If the data is stored on some other file system, then try to mount it and transfer the data to some other media such as pen drive or tape.

Either of the aforementioned methods may be able to either rectify the file system or transfer the data to some other safe location. However, if you are unable to do so then you should use a third-party Linux data recovery software to recover Linux file system. Such read-only tools are able to recover lost data and file systems using fast yet sophisticated scanning algorithms.

Stellar Phoenix Linux Data Recovery software is a Linux data recovery tool that performs data recovery of Linux file systems such as ext2, ext3, ext4, FAT12, FAT16, and FAT32. It is capable of recovering data from various hard drives such as SCSI, SATA, EIDE, and IDE. This Linux recovery tool supports various Linux distributions such as Red Hat, SUSE, Debian, Caldera, Mandrake, Sorcerer, TurboLinux, Slackware, Gentoo etc. It is compatible with Windows 7, Vista, Server 2003, XP, and 2000.

The operating system is a software whose function is to provide services to the user, whereby the operating system also serves as an interface between hardware and software. As we all know that, the computer consists of three basic parts, namely hardware, software and user.
The operating system acted as an intermediary between programs and hardware, imagine if in case there is no operating system, all programs are designed to be able to recognize all kinds of different hardware. This is where the operating system role, operating system provides services to programs about the details of hardware such as mice, keyboards, monitors, etc..

Brand operating system on the market very much at all, which distinguishes only be made by different companies and also they have different ways in terms of arrangement in the form of a memory access interface, how to use, etc. But it basically had the same role and functions. When you first run the computer, there is an initial program that must run, the program is called bootstrapping. This program manages all aspects of hardware, after the program is finished running, the next operating system will find stored in your hard disk, floppy, cd, etc.. Depending on which operating system is stored. After the operating system is found, then all the controls over hardware, be taken over by the operating system.

1. DOS (Disk Operating System) as its operating system
DOS is one of the operating system made by Microsoft, DOS itself provide services to users via a text based shell. Interface that is provided in the form of the command line, so users need to type the command with the keyboard to get a service
particular.

2 Linux as its operating system
Linux operating system is one that has the characteristics similar to UNIX operating system, Linux itself was created by Linux Torfald. Linux is open source which means all the source code can be changed and it has freely disseminated. Linux services provided is similar to DOS, but Linux can also provide services such as GUI (Graphical User Interface) based shell.

3. FreeBSD
FreeBSD is the only derivative of the UNIX operating system that is free. The operating system was mostly used as a server with a variety of purposes, because the famous toughness. To use this operating system, not too much different with the linux operating system.

Both operating systems are fundamentally different in their design and operation. Linux is an open-source derivative of Unix. Windows is the most prominent proprietary operating system, while Linux is the most prominent operating system that is free software. Unix has a two-user model. There is the root user, everything is allowed, and all other users, whose rights are severely restricted. A user must perform actions that require extended rights, he may do so only if the rights of the user gets root. This is also still the case and leads to considerable difficulties in the implementation of computer security concepts.

The first non-MS-DOS-based Windows NT 3.1 was in the years 1988 to 1993 from Microsoft Windows NT got different security architecture than UNIX. Even Windows has a powerful user named SYSTEM. However, it is not possible to register under that name. All other users have different global rights. An administrator who attempts to access a file, for which he does not have the authorization, you, like any other user, an error message. However, he has the right to file on his property make. This can be done easily via the Windows Explorer. Then he can even assign permissions and the file to use as desired.

Windows must boot from a primary partition. Linux can boot from either a primary partition or a logical partition inside an extended partition. Windows must boot from the first hard disk. Linux can boot from any hard disk in the computer. Other users without administrator rights to self-directories can be assigned. If a user the right to “take ownership” for a directory including all subdirectories that time. That is not possible under Linux. Basically, Microsoft has in the development of Windows NT recognized that the superuser model of UNIX for modern distributed computing systems is to be kept simple.

By all the above discussion, we can conclude that Linux is far better than Windows operating system. Linux have better network and processing capabilities. For server user, home or desktop user, Linux is much cheaper as compared to Windows operating system. Microsoft allows a single copy of Windows to be used on only one computer but we can run Linux on any number of computers without any additional charges. Linux as having an extremely enhanced security and lesser chances of exploits as compared to Windows.

Hi everybody

Complete process is mostly done automatically. That doesn’t imply that you just watch the computer do all work for you from start to finish.

At certain stages of the process, you are prompted to choose some options the system presents. Most questions you can answer easily, but there are some options which needs careful consideration to pick.

The options above are critical and can make the installation a total failure.

How do I know it?????

I tried it many times, and I found out the big difference. There are only two outcome of installing Linux and Windows XP on the same computer: Success or failure. No other choices.

If you want to ensure successful installations, here are 4 simple basic steps that will help you tremendously, and will make a huge difference in making the installation run smooth and produce the desired result:

1rst – MUST partition your hard disk in to 2 partitions using Windows XP.

This should be done, because in most cases each operating system should be on a separate partition.

There are some exceptions that two operating systems can work in the same partition, but it is not the proper method..

It is possible two have two Microsoft operating system on the same partition depending on their versions, but this will never work if one operating system is Linux.

So, if you need to install Linux and Windows XP on the same computer hard disk, you must use separate partition for each.

2nd -Install Windows XP First on a partition of at least 3Gigs. This is because Linux will recognize the NTFS file system used by Windows XP. So, Linux will prompted you to leave the NTFS file system intact or format it..

Once prompted if you need to format the whole drive, you will choose the option that keeps Windows XP installed.

3rd -Install Linux after you are done totally with Windows XP installation.

When you are done installing Windows XP, you will install Linux an another partition. Up until now, you have installed Windows XP and Linux on different partitions.

This will enable you to have a computer ready to be rendered a dual boot system that will give you the options of loading either operating systems: Windows XP or Linux.

However, you still have to complete one step to ensure a successful dual boot set up on your computer. In step four, I will explain what completes your successful dual boot installation.

4th -Edit lilo.conf file. After you are done installing both operating system, Linux and Windows XP, your computer will reboot. You will be amazed to find out that your computer is loading Linux without giving you the choice of loading Windows XP..

This situation is tricky and makes you think that the installation of the dual boot did not take place. This problem is resolved by editing a Linux file called lilo.conf.

Once lilo.conf is edited properly by adding a line of code that points to Windows XP operating system, you will be able to resolve the problem in order to be able to have a choice of two operating systems. Linux or Windows XP.

In Summary, don’t spend countless hours installing two operating systems unless you take into account the 4 simple steps above. Hope it helped you.
