What Is Windows 98?

Windows 98 is a widely-installed product in Microsoft's evolution of the Windows operating system for personal computers. It is an improved version for Microsoft Windows 95, and was codenamed Memphis and named after the year it was released (1998).

Compared with previous versions of Windows, Windows 98 offers numerous new features, including:
Provide a 32-bit file allocation table (FAT) that allows users to have a single-partition disk drive larger than 2 Gbytes
Came with support for USB (Universal Serial Bus) built-in, which makes it easy to plug in new devices
Support Digital Versatile Disc (DVD)
Support a new industry-standard form of power management called Advanced Configuration and Power Interface (ACPI)
Integrate Internet Explorer 4.0 into the desktop shell


There are two releases of Windows 98: the first edition and second edition. From a version standpoint, both are considered version 4.1 (with all Windows 95 releases considered v4.0). Second edition, referred by Microsoft as Windows 98SE, is a paid upgrade from the first edition released in 1999. It includes fixes for many minor issues, improved USB support, and the replacement of Internet Explorer 4.0 with Internet Explorer 5.0.

What Is Windows 95?

Windows 95 is a graphical user interface-based operating system designed for workstations at home or business. It was released in 1995 by Microsoft to be intended to integrate Microsoft's formerly separate MS-DOS and Windows products.

Windows 95 represents a significant advance over its precursor, Windows 3.1, most visibly in the graphical user interface (GUI). Following are some of the new features that Windows 95 is a widely-installed product in Microsoft's evolution of the Windows operating system for personal computers not.

Plug and Play: Allow hardware devices to be automatically installed into the computer with the proper software. Do not require jumpers to be played with jumpers to be played with.

32 Bit: 32-Bit operating system allows the computer to run faster and more efficiently.

Registry: Combine the power of multiple configuration files into two files, allowing the system configurations to be located easier.

Memory: Windows 95 has an improved memory handling processes compared to Windows 3.11

Right mouse click: Allow you new access and text manipulation by utilizing both buttons instead of one.

CD-Player: Enhanced CD-Player with improved usability and AutoPlay feature.

Although Windows 95 can run older Windows and DOS applications, it has essentially removed DOS as the underlying platform. This has meant removal of many of the old DOS limitations, such as 640K of main memory and 8-character filenames.

What Is Windows 7?

Windows 7 is the latest public release version of Microsoft Windows, a series of operating systems produced by Microsoft for use on personal computers, including home and business desktops, laptops, netbooks, tablet PCs, and media center PCs.[3] Windows 7 was released to manufacturing on July 22, 2009,[4] and reached general retail availability on October 22, 2009,[5] less than three years after the release of its predecessor, Windows Vista. Windows 7's server counterpart, Windows Server 2008 R2, was released at the same time.

Windows 7 new features have attracted a lot of people. And below are the favorite Windows 7 features by ZDNet Asia editor and others.

1. Pressing the Windows logo key together with the Left/Right Arrow keys will snap and maximise the current window to the left/right sides of the screen. I find this a terrific way to organize my windows quickly on my widescreen desktop, so that my e-mail window fills up the left half of the screen while my Web browser fills up the right half.

2. I used to install Snagit to capture screenshots, but now with Windows 7 I use the built-in Snipping Tool, which works almost as well as Snagit. The Snipping Tool lets me capture rectangular and free-form snippets of the screen.

3. Connecting Windows 7 to a projector is a lot simpler--I just press Windows+P to switch the projection on/off and to mirror or extend the desktop to the projector.

4. The Windows 7 Calculator has plenty of new useful features: Scientific, programmer and statistics functions, unit conversion (e.g. km to miles, celsius to fahrenheit) and date calculation (e.g. how many days old are you?).

5. Virtual XP Mode is very useful for running legacy applications that don't work with Windows Vista/7.

What Is Microsoft Windows?

Microsoft Windows is a series of software operating systems and graphical user interfaces produced by Microsoft. Windows dominates the personal computer world, running, by some estimates, on 90% of all personal computers. The remaining 10% are mostly Macintosh computers. Like the Macintosh operating environment, Windows provides a graphical user interface (GUI), virtual memory management, multitasking, and support for many peripheral devices.

What Is DOS?

DOS, an acronym for Disk Operating System, in a general sense, DOS refers to just about any operating system. More commonly, it describes the operating system Microsoft developed in 1981 for IBM's line of personal computers. Though syntactically distinct, DOS shares similarities with a Unix shell. It has a command-line interface and analogs to many common Unix commands. However, DOS is a 16-bit, single-user operating system that does not support multi-tasking. It is far easier to administer than Unix, but less powerful. Compared to graphical interfaces such as Windows and Mac OS X, it's also not particularly user-friendly.

With the development of Windows, MS-DOS has faded in importance. However, you can still run some DOS commands at the command prompt in current versions of Windows, which can be useful in situations where a graphical interface is less efficient.

For some time, it has been widely acknowledged that DOS is insufficient for modern computer applications. Microsoft Windows helped alleviate some problems, but still, it sat on top of DOS and relied on DOS for many services. Even Windows 95 sat on top of DOS. Newer operating systems, such as Windows NT and OS/2 Warp, do not rely on DOS to the same extent, although they can execute DOS-based programs. It is expected that as these operating systems gain market share, DOS will eventually disappear. In the meantime, Caldera, Inc. markets a version of DOS called DR-OpenDOS that extends MS-DOS in significant ways.

What Is Data?

Data (plural of datum, which is seldom used) are distinct pieces of information, usually formatted in a special way. It can exist in a variety of forms, including knowledge stored in a human mind, text written or printed on paper, and patterns of bytes stored in electronic memory chip, on magnetic media.

In computer science, data is one of the two broad categories of computer software. It is anything in a form suitable for use with a computer. Data is often distinguished from the other category – programs, which are sets of instructions for manipulating data. In this sense, data is thus everything that is not program code.

In an alternate usage, data is often referred to binary files (which are not human-readable) as distinguished from human-readable text. The total amount of digital data in 2007 was estimated to be 281 billion gigabytes.

What Is Photo Recovery?

Photo Recovery can be considered a subset of the overall Data Recovery field.

Photo Recovery is the process of retrieving digital photographs that has become inaccessible using normal methods for any reason from damaged, failed, corrupted, or inaccessible secondary storage media.


Regardless of the cause of your photo loss, without physical problem, photo recovery software can help you get back your lost photos.

What Is Partition Recovery?

Partition is a part of hard drive or a section. It is also an independent logical storage unit. One hard disk can be divided into one or more partitions. Each partition is regarded as one logical storage unit, and normally contains one file system. To partition a hard drive, you may use "fdisk" command or partition tools from the third party supporters. Typically, a partition is assigned one station letter (C:, D: etc). Once you partition a hard drive, the partition table must be rewritten. Because the partition table is a list displays the layout of which parts of the table are reserved for file systems.

Partition Recovery is a method of recovering your lost or deleted partition.

What Is Raw Recovery?

RAW Recovery refers to read files without reference to an operating system. Normal recovery method cannot scan a drive which has suffered a serious corruption or data overwriting. RAW scan can locate the files without the aid of file system, therefore, you can choose to use RAW recovery after operating system corruption and overwriting. Using RAW recovery to scan the target device, the list of lost files will be displayed in a tree according to the file type. RAW recovery will still work when the temporary copies are being created, as it can recover data from the partition where operating system and application software are installed.

What Is Deleting?

Deleting is the act of removal existing text,data, records, files and folders from computer's file system or from other storage devices. In our daily life, we may lose some important data by accidental deleting with Delete Key such as ‘Shift + Del' without backup, emptying Recycle Bin, deleting data instead of saving by accidentally pressing wrong button.

When you lose your data due to accidental deleting, it doesn't mean your data is gone forever. The data is still in your PC. Windows marks files for deletion and removes them from the file system database. You can get back your deleted data as long as your original data is not overwritten.

What Is Virus

Virus (here refers to computer virus) is a software program designed to infect, destroy or interfere with a computer or software program. Computer virus can copy itself and can be transmitted between computers via networks (especially the Internet) or removable storage such as CDs, USB drives, floppy disks, etc.

Viruses are sometimes confused with computer worms and Trojan horses, which are technically different. A worm can exploit security vulnerabilities to spread itself automatically to other computers through networks, while a Trojan is a program that appears harmless but hides malicious functions. Worms and Trojans, like viruses, may harm a computer system's data or performance.

While many viruses do damages to files and disk structures, many are just nuisances or exhibit strange behavior such as playing music or putting funny phrases on the screen when the system is booted.

Once your data get lost due to virus infection, you should scan and remove the virus with anti-virus software immediately. Even though the virus cannot be removed, you can still use photo recovery software to restore lost pictures.

What Is Formatting?

Formatting is to prepare a storage medium such as a hard drive or flash drive to be recognized, read or written by computer. Formatting a disk involves testing the disk and writing a new file system onto the disk.

When you format a disk, the operating system erases all book keeping information on the disk, tests the disk to make sure all sectors are reliable, marks bad sectors (that is, those that are scratched), and creates internal address tables that will used later to locate information.

Formatting has low- level and high-level. Low-level or physical formatting sets certain properties of the disk such as the interleave factor, and determines what type of disk controller can access the disk (e.g., RLL or MFM) and writes all necessary stored data to enable the storage device to read the media. Almost all hard disks that you purchase have already had a low-level formatting, so it is unnecessary to perform a low-level formatting by yourself unless you want to change the interleave factor or make the disk accessible by a different type of disk controller, as low-level formatting will erase all data on the disk.

High-level or logical formatting writes data used by the operating system, such as allocation information and directories onto media which has already been physically formatted.

Most users only perform high-level formatting such as accidentally formatting a disk.
