Hitachi, Ltd. (株式会社日立製作所 Kabushiki-gaisha Hitachi Seisakusho?) (Japanese pronunciation: [çitatɕi]) is a Japanese multinational engineering and electronics conglomerate company headquartered in Chiyoda, Tokyo, Japan. It is the parent of the Hitachi Group (Hitachi Gurūpu) and forms part of the DKB Group of companies. Hitachi is a diversified company and has 11 business segments: Information and Telecommunication Systems, Electrical Systems, Social and Industrial Systems, Automotive Systems, Electronic Component Devices, Construction, and Financial services.

Hitachi is listed on the Tokyo Stock Exchange and is a constituent of the Nikkei 225 and TOPIX indices. Hitachi was ranked 38 on the 2012 Fortune Global 500 list and was ranked 129 on the 2012 Forbes Global 2000 list.

Hitachi was founded in 1910 by electrical engineer Namihei Odaira. The company’s first product was Japan’s first 5-horsepower electric induction motor, initially developed for use in copper mining. Odaira’s company soon became the domestic leader in electric motors and electric power industry infrastructure.

The company began as an in-house venture of Fusanosuke Kuhara‘s mining company in Hitachi, Ibaraki prefecture. Odaira moved headquarters to Tokyo in 1918. Long before that, he coined the company’s toponymic name by superimposing two kanji characters: hi meaning “sun” and tachi meaning “rise”. The young company’s national aspirations were conveyed by its original brand mark, which evoked Japan’s imperial rising sun flag.

Hitachi entered talks with Mitsubishi Heavy Industry in August 2011 about a potential merger of the two companies, in what would have been the largest merger between two Japanese companies in history.[3][4] The talks subsequently broke down and were suspended.[5]

In October 2012 Hitachi agreed to acquire the United Kingdom-based nuclear energy company Horizon Nuclear Power, which plans to construct up to six nuclear power plants in the UK, from E.ON and RWE for £700 million.

 

Computer software is a general term used to describe a collection of computer programs, procedures and documentation that perform some tasks on a computer system.[41] The term includes application software such as word processors which perform productive tasks for users, system software such as operating systems, which interface with computer hardware to provide the necessary services for application software, and middleware which controls and co-ordinates distributed systems.

Software applications for word processing, Internet browsing, Internet faxing, e-mail and other digital messaging, multimedia playback, computer game play and computer programming are common. The user of a modern personal computer may have significant knowledge of the operating environment and application programs, but is not necessarily interested in programming nor even able to write programs for the computer. Therefore, most software written primarily for personal computers tends to be designed with simplicity of use, or “user-friendliness” in mind. However, the software industry continuously provide a wide range of new products for use in personal computers, targeted at both the expert and the non-expert user.

PC(Personal Computer)

Microsoft Windows

Microsoft Windows is the collective brand name of several software operating systems by Microsoft. Microsoft first introduced an operating environment named Windows in November 1985 as an add-on to MS-DOS in response to the growing interest in graphical user interfaces (GUIs)[42][43] generated by Apple’s 1984 introduction of the Macintosh. The most recent client and server version of Windows are Windows 8 and Windows Server 2012, respectively, which was available at retail on October 26, 2012.

OS X

Main article: OS X

OS X (formerly Mac OS X) is a line of operating systems developed, marketed, and sold by Apple Inc.. OS X is the successor to the original Mac OS, which had been Apple’s primary operating system since 1984. OS X is a Unix-based graphical operating system. The most recent version of OS X is OS X Mountain Lion.

AmigaOS

AmigaOS is the default native operating system of the Amiga personal computer. It was developed first by Commodore International, and initially introduced in 1985 with the Amiga 1000. Early versions (1.0-3.9) run on the Motorola 68k series of 16-bit and 32-bit microprocessors, while the newer AmigaOS 4 runs only on PowerPC microprocessors. On top of a preemptive multitasking kernel called Exec, it includes an abstraction of the Amiga’s unique hardware, a disk operating system called AmigaDOS, a windowing system API called Intuition and a graphical user interface called Workbench. A command line interface called AmigaShell is also available and integrated into the system. The GUI and the CLI complement each other and share the same privileges. The current holder of the Amiga intellectual properties is Amiga Inc. They oversaw the development of AmigaOS 4 but did not develop it themselves, contracting it instead to Hyperion Entertainment. On 20 December 2006, Amiga Inc terminated Hyperion’s license to continue development of AmigaOS 4. However, in 30 September 2009, Hyperion was granted an exclusive, perpetual, worldwide right to AmigaOS 3.1 in order to use, develop, modify, commercialize, distribute and market AmigaOS 4.x and subsequent versions of AmigaOS (including AmigaOS 5).

Linux.

Linux is a family of Unix-like computer operating systems. Linux is one of the most prominent examples of free software and open source development: typically all underlying source code can be freely modified, used, and redistributed by anyone.[44] The name “Linux” comes from the Linux kernel, started in 1991 by Linus Torvalds. The system’s utilities and libraries usually come from the GNU operating system, announced in 1983 by Richard Stallman. The GNU contribution is the basis for the alternative name GNU/Linux.[45]

Known for its use in servers as part of the LAMP application stack, Linux is supported by corporations such as Dell, Hewlett-Packard, IBM, Novell, Oracle Corporation, Red Hat, Canonical Ltd. and Sun Microsystems. It is used as an operating system for a wide variety of computer hardware, including desktop computers, netbooks, supercomputers,[46] video game systems, such as the PlayStation 3, several arcade games, and embedded devices such as mobile phones, portable media players, routers, and stage lighting systems.

 

Server OS

Server-oriented operating systems tend to have certain features in common that make them more suitable for the server environment, such as

  • GUI not available or optional
  • ability to reconfigure and update both hardware and software to some extent without restart,
  • advanced backup facilities to permit regular and frequent online backups of critical data,
  • transparent data transfer between different volumes or devices,
  • flexible and advanced networking capabilities,
  • automation capabilities such as daemons in UNIX and services in Windows, and
  • tight system security, with advanced user, resource, data, and memory protection.

Server-oriented operating systems can, in many cases, interact with hardware sensors to detect conditions such as overheating, processor and disk failure, and consequently alert an operator or take remedial measures themselves.

 

FreeBSD – Based on the original BSD, a free alternative to UNIX, FreeBSD is free and open source and is known for its stability and its devil mascot.

OpenBSD – Another BSD variant, OpenBSD is known for its security-conscious configuration. The developers of the OS are also responsible for OpenSSH and OpenSSL.

Solaris – Once the brain child of the now defunct Sun Microsystems, Solaris is a commercial UNIX variant that uses many of the open tools available for BSD and Linux. In addition, there is a free version called OpenSolaris. All Solaris products are now owned by Oracle.

Windows Server is a brand name for a group of server operating systems released by Microsoft Corporation. All are part of Microsoft Servers. This brand includes the following software:

Microsoft has also produced Windows Small Business Server and Windows Essential Business Server (discontinued), software bundles which includes a Windows Server operating system and some other Microsoft Servers products.[3][4][5]

 

Mac OS X Server – Although most commonly perceived as a desktop OS, Mac OS X is a full-fledged Unix variant and contains many of the features of BSD. Like most commercial Unix offerings, OS X Server is designed to be run on Apple hardware, although there is a free and open source version, Darwin, that could technically run on anything.

Other Commercial UNIX variants – Many of the large server companies included their own proprietary UNIX operating systems already installed on their servers. Some of the big names were IBM’s AIX and HP’s HP-UX.

Embedded OS

An embedded operating system is an operating system for embedded computer systems. These operating systems are designed to be compact, efficient at resource usage, and reliable, forsaking many functions that non-embedded computer operating systems provide, and which may not be used by the specialized applications they run. They are frequently also referred to as real-time operating systems, and the term RTOS is often used (but it’s not correct to call them so) as a synonym for embedded operating system.

List of embedded OS:

Personal digital assistants (PDAs)

Digital media players

Smartphones and Mobile phones

Routers

Other embedded

Mobile OS

Operating system that designed to be used on mobile devices, such as mobile phones, PDAs, Handheld, most of them are usually embedded. List of them can be seen above
