Diffrentiate Mac Os vs Windows vs UNIX

Mac OS is the computer operating system for Apple Computer's Macintosh line of personal computers and workstations. A popular feature of its latest version, Mac OS X , is a desktop interface with some 3-D appearance characteristics. OS X has a modular design intended to make it easier to add new features to the operating system in the future.
Microsoft Windows is a series of operating systems produced by Microsoft.
Microsoft introduced an operating environment named Windows on November 20, 1985 as an add-on to MS-DOS in response to the growing interest in graphical user interfaces (GUIs).Microsoft Windows came to dominate the world's personal computer market, overtaking Mac OS, which had been introduced in 1984.
Unix (officially trademarked as UNIX, sometimes also written as Unix) is a multitasking, multi-user computer operating system originally developed in 1969 by a group of AT&T employees at Bell Labs, including Ken Thompson, Dennis Ritchie, Brian Kernighan, Douglas McIlroy, and Joe Ossanna. 
Unix operating systems are widely used in servers, workstations, and mobile devices. The Unix environment and the client–server program model were essential elements in the development of the Internet and the reshaping of computing as centered in networks rather than in individual computers.

Windows Mobile

• Windows Mobile is a mobile operating system developed by Microsoft that was used in smartphones and mobile devices, but by 2011 was rarely supplied on new phones. The last version is "Windows Mobile 6.5.5"; it is superseded by Windows Phone 7, which does not run Windows Mobile software. Unlike operating systems for desktop computers, it is usually not possible to upgrade the operating system on a Microsoft based mobile phone via official and legal means, even by a later release of the same basic operating system let alone a different one; hardware replacement is the only way for less popular and older devices.
• Most Windows Mobile devices come with a stylus, which is used to enter commands by tapping it on the screen. Microsoft announced a completely new phone platform, Windows Phone 7, at the Mobile World Congress in Barcelona on February 15, 2010. Phones running Windows Mobile 6.x will not be upgradeable to version 7.

Most versions of Windows Mobile for Pocket PC have these standard features:

• Today screen shows the current date, owner information, upcoming appointments, e-mail messages, and tasks. (Home screen in later WM6.5 builds)
• The task bar shows the current time and the audio volume.
• Office Mobile, a suite of Mobile versions of Microsoft Office applications, including Outlook Mobile.
• Internet Explorer Mobile, an Internet browser developed by Microsoft for Pocket PC and Handheld PC that comes loaded by default with Windows Mobile and Windows CE for Handheld PC.
• Windows Media Player for Windows Mobile.
• Internet Connection Sharing (ICS), which in mobile phones allows the phone to make its Internet connection available to computers via USB and Bluetooth.
• File system similar to that of Windows 9x/Windows NT, with support for many of the same file types.
• Ability to multitask.

Hardware

There are three versions of Windows Mobile for various hardware devices:

• Windows Mobile Professional runs on smartphones with touchscreens
• Windows Mobile Standard runs on phones without touchscreens
• Windows Mobile Classic which runs on 'Windows Mobile Classic devices' (Pocket PCs). 

Windows Mobile Classic devices (Pocket PC)

Main article: Pocket PC

A 'Windows Mobile Classic device' is a Windows Mobile personal digital assistant (PDA) that does not have telephone functionality. It was formerly known as the Pocket PC. It was the original intended platform for the Windows Mobile operating system. These devices consisted of both standalone Pocket PC devices without mobile phone capabilities, and those that included mobile phone capabilities. The most current name of Windows Mobile intended for use on Pocket PCs is officially "Windows Mobile 6 Professional" for devices with mobile phone capabilities and "Windows Mobile 6 Classic" for devices without mobile phone capabilities.

Windows Mobile Smartphones

Main article: Smartphone

The 'Windows Mobile' (Microsoft's term for its range of smartphones) became the next hardware platform after the Pocket PC to run Windows Mobile, and debuted with the release of Pocket PC 2002. Although in the broad sense of the term "Smartphone", both Pocket PC phones and Microsoft branded Smartphones each fit into this category, it should be noted that Microsoft's use of the term "Smartphone" includes only more specific hardware devices that differ from Pocket PC phones. Such Smartphones were originally designed without touchscreens, intended to be operated more efficiently with only one hand, and typically had lower display resolution than Pocket PCs. Microsoft's focus for the Smartphone platform was to create a device that functioned well as a phone and data device in a more integrated manner.

 

Windows CE

Microsoft Windows CE (now officially known as Windows Embedded Compact and previously also known as Windows Embedded CE , and sometimes abbreviated WinCE) is an operating system developed by Microsoft for embedded systems. Windows CE is a distinct operating system and kernel, rather than a trimmed-down version of desktop Windows. It is not to be confused with Windows Embedded Standard which is an NT-based componentized version of desktop Microsoft Windows.
Microsoft licenses Windows CE to OEMs and device makers. The OEMs and device makers can modify and create their own user interfaces and experiences, while Windows CE provides the technical foundation to do so.

Windows

Microsoft Windows is a series of operating systems produced by Microsoft.
Microsoft introduced an operating environment named Windows on November 20, 1985 as an add-on to MS-DOS in response to the growing interest in graphical user interfaces (GUIs). Microsoft Windows came to dominate the world's personal computer market, overtaking Mac OS, which had been introduced in 1984. As of October 2009, Windows had approximately 90% of the market share of the client operating systems for usage on the Internet.

Utility Programs

Utility software is a kind of system software designed to help analyze, configure, optimize and maintain the computer. A single piece of utility software is usually called a utility or tool.
Utility software should be contrasted with application software, which allows users to do things like creating text documents, playing games, listening to music or surfing the web. Rather than providing these kinds of user-oriented or output-oriented functionality, utility software usually focuses on how the computer infrastructure (including the computer hardware, operating system, application software and data storage) operates. Due to this focus, utilities are often rather technical and targeted at people with an advanced level of computer knowledge.

UNIX

Unix (officially trademarked as UNIX, sometimes also written as Unix) is a multitasking, multi-user computer operating system originally developed in 1969 by a group of AT&T employees at Bell Labs, including Ken Thompson, Dennis Ritchie, Brian Kernighan, Douglas McIlroy, and Joe Ossanna. The Unix operating system was first developed in assembly language, but by 1973 had been almost entirely recoded in C, greatly facilitating its further development and porting to other hardware. Today's Unix systems are split into various branches, developed over time by AT&T as well as various commercial vendors and non-profit organizations.

Application Software

Application software is a subclass of computer software that employs the capabilities of a computer directly and thoroughly to a task that the user wishes to perform.

A program or group of programs designed for end users. Application software can be divided into two general classes: systems software and applications software. Systems software consists of low-level programs that interact with the computer at a very basic level. This includes operating systems, compilers, and utilities for managing computer resources.
In contrast, applications software (also called end-user programs) includes database programs, word processors, and spreadsheets. Figuratively speaking, applications software sits on top of systems software because it is unable to run without the operating system and system utilities.

System Software

System software refers to the files and programs that make up your computer's operating system. System files include libraries of functions, system services, drivers for printers and other hardware, system preferences, and other configuration files. The programs that are part of the system software include assemblers, compilers, file management tools, system utilites, and debuggers.
The system software is installed on your computer when you install your operating system. You can update the software by running programs such as "Windows Update" for Windows or "Software Update" for Mac OS X. Unlike application programs, however, system software is not meant to be run by the end user. For example, while you might use your Web browser every day, you probably don't have much use for an assembler program (unless, of course, you are a computer programmer).

Operating System (OS)

An operating system (OS) is software, consisting of programs and data, that runs on computers, manages computer hardware resources, and provides common services for execution of various application software.
)The most important program that runs on a computer. Every general-purpose computer must have an operating system to run other programs. Operating systems perform basic tasks, such as recognizing input from the keyboard, sending output to the display screen, keeping track of files and directories on the disk, and controlling peripheral devices such as disk drives and printers.
For large systems, the operating system has even greater responsibilities and powers. It is like a traffic cop -- it makes sure that different programs and users running at the same time do not interfere with each other. The operating system is also responsible for security, ensuring that unauthorized users do not access the system.
Operating systems can be classified as follows:

multi-user : Allows two or more users to run programs at the same time. Some operating systems permit hundreds or even thousands of concurrent users.

multiprocessing : Supports running a program on more than one CPU.

multitasking : Allows more than one program to run concurrently.

multithreading : Allows different parts of a single program to run concurrently.

real time: Responds to input instantly. General-purpose operating systems, such as DOS and UNIX, are not real-time.

Operating systems provide a software platform on top of which other programs, called application programs, can run. The application programs must be written to run on top of a particular operating system. Your choice of operating system, therefore, determines to a great extent the applications you can run. For PCs, the most popular operating systems are DOS, OS/2, and Windows, but others are available, such as Linux.
As a user, you normally interact with the operating system through a set of commands. For example, the DOS operating system contains commands such as COPY and RENAME for copying files and changing the names of files, respectively. The commands are accepted and executed by a part of the operating system called the command processor or command line interpreter. Graphical user interfaces allow you to enter commands by pointing and clicking at objects that appear on the screen.

Network operating system (NOS)

Networking operating system (NOS), also referred to as the Dialoguer, is the software that runs on a server and enables the server to manage data, users, groups, security, applications, and other networking functions.The network operating system is designed to allow shared file and printer access among multiple computers in a network, typically a local area network (LAN), a private network or to other networks.

Characteristics 

Network Operating Systems are based on a client/server architecture in which a server enables multiple clients to share resources.

The Network Operating System can also do the following:

• Centrally manage network resources, such as programs, data and devices.
• Secure access to a network.
• Allow remote users to connect to a network.
• Allow users to connect to other networks like the Internet.
• Back up data and make sure it's always available.
• Allow for simple additions of clients and resources.
• Monitor the status and functionality of network elements.
• Distribute programs and software updates to clients.
• Ensure efficient use of a server's capabilities.

Multitasking

Multitasking, in an operating system, is allowing a user to perform more than one computer task (such as the operation of an application program) at a time. The operating system is able to keep track of where you are in these tasks and go from one to the other without losing information.
Microsoft Windows 2000, IBM's OS/390, and Linux are examples of operating systems that can do multitasking (almost all of today's operating systems can). When you open your Web browser and then open Word at the same time, you are causing the operating system to do multitasking.

MS-DOS

• MS-DOS (; short for Microsoft Disk Operating System) is an operating system for x86-based personal computers. It was the most commonly used member of the DOS family of operating systems, and was the main operating system for IBM PC compatible personal computers during the 1980s to the mid 1990s, until it was gradually superseded by operating systems offering a graphical user interface (GUI), in particular by various generations of the Microsoft Windows operating system.
• MS-DOS grew from a 1981 request by IBM for an operating system for its IBM PC range of personal computers. Microsoft quickly bought the rights to QDOS (Quick and Dirty Operating System), also known as 86-DOS, from Seattle Computer Products, and began work on modifying it to meet IBM's specification. The first edition, MS-DOS 1.0, was launched in 1982.
• MS-DOS (Microsoft Disk Operating System) was the Microsoft-marketed version of the first widely-installed operating system in personal computers. It was essentially the same operating system that Bill Gate's young company developed for IBM as Personal Computer .

Macintosh OS

• Mac OS is a series of graphical user interface-based operating systems developed by Apple Inc. (formerly Apple Computer, Inc.) for their Macintosh line of computer systems. 
• The original form of what Apple would later name the "Mac OS" was the integral and unnamed system software first introduced in 1984 with the original Macintosh, usually referred to simply as the System software.

LINUX

• is a computer operating system which is based on free and open source software.
• Linux can be installed on a wide variety of computer hardware, ranging from mobile phones, tablet computers, routers and video game consoles, to desktop computers, mainframes and supercomputers. Linux is a leading server operating system, and runs the 10 fastest supercomputers in the world.

Graphical user interface(GUI)

• In computing, a graphical user interface (GUI, sometimes pronounced gooey) is a type of user interface that allows users to interact with electronic devices with images rather than text commands.
• GUI's can be used in computers, hand-held devices such as MP3 players, portable media players or gaming devices, household appliances and office equipment.
• A GUI represents the information and actions available to a user through graphical icons and visual indicators such as secondary notation, as opposed to text-based interfaces, typed command labels or text navigation.

BOOTING

• To boot (as a verb; also "to boot up") a computer is to load an operating system into the computer's main memory or random access memory (RAM)
• In computing, booting (also known as booting up) is a bootstrapping process that starts operating systems when the user turns on a computer system. A boot sequence is the initial set of operations that the computer performs when power is switched on. The boot loader typically loads the main operating system for the computer.
• Beginning with the IBM 701 in the 1950s to the present, booting has been used to load operating systems into the main memory of mainframe computers, mini computers, and personal computers.

Compare solid-state storage to magnetic and optical storage media

• A solid-state drive (SSD) is a data storage device that uses solid-state memory to store persistent data with the intention of providing access in the same manner of a traditional block i/o hard disk drive. SSDs are distinguished from traditional hard disk drives (HDDs), which are electromechanical devices containing spinning disks and movable read/write heads. SSDs, in contrast, use microchips which retain data in non-volatile memory chips^, and contain no moving parts.
• Magnetic storage and magnetic recording are terms from engineering referring to the storage of data on a magnetized medium. Magnetic storage uses different patterns of magnetization in a magnetizable material to store data and is a form of non-volatile memory.
• Optical storage is a term from engineering referring to the storage of data on an optically readable medium. Data is recorded by making marks in a pattern that can be read back with the aid of light, usually a beam of laser light precisely focused on a spinning disc.

Teleconferencing technology

• Teleconferencing technology has provided businesses with an entirely new way of communicating over long distances.
• In fact, it helps business save money on travel expenses and has also helped business owners increase the productivity of their business by providing them with the ability to communicate via telecommunication methods.
• Teleconferencing technology gives businesses the ability to have meetings over long distances, conduct business briefings, employee training sessions, workshops, seminars, lectures and more between individuals who might not otherwise be able to easily get together.

Solid-state storage

• Solid-state storage is a nonvolatile, removable storage medium that employs integrated circuits (ICs) rather than magnetic or optical media. It is the equivalent of large-capacity, nonvolatile memory. 
•  Solid-state storage media lags behind electromechanical drives in terms of storage capacity. As of this writing, flash memory USB devices can store up to approximately 1 gigabyte (GB), whereas hard drives commonly hold 100 GB or more.

List of components and features that the student should consider when purchasing a computer.

•  Verify first that the computer has no physical damage, inside and outside the case.So the computer will be performed.
• Make sure a computer comes with any Cd's has no damage, and for the operating system that will be performed or to installed.
• See the details of computer that could manufacturer of the company.

Computer’s power management settings

• Power management of personal computers (PCs) and monitors has the potential to save significant amounts of electricity as well as deliver other economic and environmental benefits
• One of the leading power-management advocacy organizations in the United States, recommends the following power-management settings:   Monitor/display sleep: Turn off after 15 minutes or less. Turn off hard drives/hard disk sleep: 15 minutes or less.System standby/sleep: After 30 minutes or less. 
• You can save energy, save money, and help the environment by activating power management features on your computer. Benefits include. Cutting the electricity used by your PCs roughly in half, saving $25–75 per PC annually. Estimate your savings using our online calculator. Enhancing data security by reducing the chance that valuable personal information is displayed on an unattended PC.Saving time by eliminating the daily wait for computers to boot up.Helping the environment. Saving energy reduces air pollution associated with the burning of fossil fuels, and ultimately lowers the risk of global warming.

Dr. M.E." Ted " Hoff Engineer and Inventor of Microprocessor

• He designed the computer-on-a-chip microprocessor (1968), which came on the market as the Intel 4004 (1971), starting the microcomputer industry.
• November of 1971 Intel publicly introduced the world's first single chip microprocessor called the Intel 4004.  It was invented by Intel engineers Ted Hoff, Federico Faggin, and Stan Mazor.  The Intel 4004 was smaller than a thumbnail, packed 2,300 transistors, executed 60,000 operations a second, and sold for $200 at the time.
