PC Tools (software)
PC Tools is a collection of software utilities for DOS developed by Central Point Software. History of development The original PC Tools package was first developed as a suite of utilities for DOS, released for retail in 1985 for $39.95. With the introduction of version 4.0, the name was changed to PC Tools Deluxe, and the primary interface became a colorful graphical shell (previously the shell resembled PC BOSS and was monochrome.) By version 7.0 of the package in 1991 several Windows programs had been added to it. Though the 7.0 version sold well, it was criticised in computer trade publications for being overcomplicated and riddled with bugs. It was widely considered to have been rushed to publication, despite the objections of many of Central Point Software's employees. PC Tools PRO (Version 9) for DOS was the last stable version released by Central Point Software before acquisition. In June 1994 Central Point was acquired by their top competitor Symantec. The ...

Central Point Software
Central Point Software, Inc. (CP, CPS, Central Point) was a leading software utilities maker for the personal computer, PC market, supplying utilities software for the DOS and Microsoft Windows markets. It also made Apple II copy programs. Through a series of mergers, the company was ultimately acquired by Symantec in 1994. History CPS was founded by Michael Burmeister-Brown (Mike Brown) in 1980 in Central Point, Oregon, for which the company was named. Building on the success of its Copy II PC backup utility, it moved to Beaverton, Oregon. In 1993 CPS acquired the XTree Company. It was itself acquired by NortonLifeLock, Symantec in 1994, for around $60 million. Products The company's most important early product was a series of utilities which allowed exact duplicates to be made of copy protection, copy-protected floppy disk, diskettes. The first version, Copy II Plus v1.0 (for the Apple II series, Apple II), was released in June 1981. With the success of the IBM Personal Comp ...

File Allocation Table
File Allocation Table (FAT) is a file system developed for personal computers. Originally developed in 1977 for use on floppy disks, it was adapted for use on hard disks and other devices. It is often supported for compatibility reasons by current operating systems for personal computers and many mobile devices and embedded systems, allowing interchange of data between disparate systems. The increase in disk drives capacity required three major variants: FAT12, FAT16 and FAT32. The FAT standard has also been expanded in other ways while generally preserving backward compatibility with existing software. FAT is no longer the default file system for Microsoft Windows computers. FAT file systems are still commonly found on floppy disks, flash and other solid-state memory cards and modules (including USB flash drives), as well as many portable and embedded devices. FAT is the standard file system for digital cameras per the DCF specification. Overview Concepts ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Utility Software
Utility software is software designed to help analyze, configure, optimize or maintain a computer. It is used to support the computer infrastructure - in contrast to application software, which is aimed at directly performing tasks that benefit ordinary users. However, utilities often form part of the application . For example, a batch job may run user-written code to update a database and may then include a step that runs a utility to back up the database, or a job may run a utility to compress a disk before copying files. Although a basic set of utility programs is usually distributed with an operating system (OS), and this first party utility software is often considered part of the operating system, users often install replacements or additional utilities. Those utilities may provide additional facilities to carry out tasks that are beyond the capabilities of the operating system. Many utilities that might affect the entire computer system require the user to have elevated pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MS-DOS 6
MS-DOS ( ; acronym for Microsoft Disk Operating System, also known as Microsoft DOS) is an operating system for x86-based personal computers mostly developed by Microsoft. Collectively, MS-DOS, its rebranding as IBM PC DOS, and a few operating systems attempting to be compatible with MS-DOS, are sometimes referred to as "DOS" (which is also the generic acronym for disk operating system). MS-DOS was the main operating system for IBM PC compatibles during the 1980s, from which point it was gradually superseded by operating systems offering a graphical user interface (GUI), in various generations of the graphical Microsoft Windows operating system. IBM licensed and re-released it in 1981 as PC DOS 1.0 for use in its PCs. Although MS-DOS and PC DOS were initially developed in parallel by Microsoft and IBM, the two products diverged after twelve years, in 1993, with recognizable differences in compatibility, syntax, and capabilities. Beginning in 1988 with DR-DO ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Microsoft AntiVirus
Microsoft Anti-Virus (MSAV) is an antivirus program introduced by Microsoft for its MS-DOS operating system. The program first appeared in MS-DOS version 6.0 (1993) and last appeared in MS-DOS 6.22. The first version of the antivirus program was basic, had no inbuilt update facility (updates had to be obtained from a BBS and manually installed by the user) and could scan for 1,234 different viruses. Microsoft Anti-Virus for Windows (MWAV), included as part of the package, was a front end that allowed MSAV to run properly on Windows 3.1x. In 2009, Microsoft launched an in-house antivirus solution named Microsoft Security Essentials, which later was phased out in favor of Microsoft Defender. History Microsoft Anti-Virus was supplied by Central Point Software Inc. (later acquired by Symantec in 1994 and integrated into Symantec's Norton AntiVirus product) and was a stripped-down version of the Central Point Anti-Virus (CPAV) product which Central Point Software Inc., had license ...

Computer Virus
A computer virus is a type of computer program that, when executed, replicates itself by modifying other computer programs and inserting its own code. If this replication succeeds, the affected areas are then said to be "infected" with a computer virus, a metaphor derived from biological viruses. Computer viruses generally require a host program. The virus writes its own code into the host program. When the program runs, the written virus program is executed first, causing infection and damage. A computer worm does not need a host program, as it is an independent program or code chunk. Therefore, it is not restricted by the host program, but can run independently and actively carry out attacks. Virus writers use social engineering deceptions and exploit detailed knowledge of security vulnerabilities to initially infect systems and to spread the virus. Viruses use complex anti-detection/stealth strategies to evade antivirus software. Motives for creating viruses can inclu ...

Defragmentation
In the maintenance of file systems, defragmentation is a process that reduces the degree of fragmentation. It does this by physically organizing the contents of the mass storage device used to store files into the smallest number of contiguous regions (fragments, ''extents''). It also attempts to create larger regions of free space using compaction to impede the return of fragmentation. Some defragmentation utilities try to keep smaller files within a single directory together, as they are often accessed in sequence. Defragmentation is advantageous and relevant to file systems on electromechanical disk drives (hard disk drives, floppy disk drives and optical disk media). The movement of the hard drive's read/write heads over different areas of the disk when accessing fragmented files is slower, compared to accessing the entire contents of a non-fragmented file sequentially without moving the read/write heads to seek other fragments. Causes of fragmentation Fragmenta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Disk Editor
A disk editor is a computer program that allows its user to read, edit, and write raw data (at character or hexadecimal, byte-levels) on disk drives (e.g., hard disks, USB flash disks or removable media such as a floppy disks); as such, they are sometimes called ''sector editors,'' since the read/write routines built into the electronics of most disk drives require to read/write data in chunks of sectors (usually 512 bytes). Many disk editors can also be used to edit the contents of a running computer's memory or a disk image. Unlike ''hex editors,'' which are used to edit files, a disk editor allows access to the underlying disk structures, such as the master boot record (MBR) or GUID Partition Table (GPT), file system, and directories. On some operating systems (like Unix or Unix-like) most hex editors can act as disk editors just opening block devices instead of regular files. Programmers can use disk editors to understand these structures and test whether their impleme ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Windows
Windows is a group of several proprietary graphical operating system families developed and marketed by Microsoft. Each family caters to a certain sector of the computing industry. For example, Windows NT for consumers, Windows Server for servers, and Windows IoT for embedded systems. Defunct Windows families include Windows 9x, Windows Mobile, and Windows Phone. The first version of Windows was released on November 20, 1985, as a graphical operating system shell for MS-DOS in response to the growing interest in graphical user interfaces (GUIs). Windows is the most popular desktop operating system in the world, with 75% market share , according to StatCounter. However, Windows is not the most used operating system when including both mobile and desktop OSes, due to Android's massive growth. , the most recent version of Windows is Windows 11 for consumer PCs and tablets, Windows 11 Enterprise for corporations, and Windows Server 2022 for servers.
