|MAC Address||Stands for "Media Access Control Address," and no, it is not related Apple Macintosh computers. A MAC address is a hardware identification number that uniquely identifies each device on a network. The MAC address is manufactured into every network card, such as an Ethernet card or Wi-Fi card, and therefore cannot be changed.|

|Mac OS:||This is the operating system that runs on Macintosh computers. The Mac OS has been around since the first Macintosh was introduced in 1984. Since then, it has been continually updated and many new features have been added to it. Each major OS release is signified by a new number (i.e. Mac OS 8, Mac OS 9).|
This is the name of the computers that are made by Apple Computer. The first Macintosh was introduced in 1984 and was seen as a major innovation in computing ease-of-use. The Macintosh was the first personal computer to use a graphical user interface (GUI), which allowed the user to interact with the operating system by using a mouse to click and drag objects. Since 1984, Apple has continually revised and upgraded the Macintosh product line and now makes both laptop and desktop versions of the Macintosh. The Macintosh product line includes the following models:|
1. Power Mac - a high-performance desktop computer for professionals
2. PowerBook - a high-performance laptop computer for professionals.
3. iMac - a creatively designed consumer desktop computer
4. iBook - a laptop computer for students and home users
5. eMac - an all-in-one desktop computer for educators and entry-level consumers
6. Mac mini - a super-small, fully functional computer sold without a monitor, keyboard, or mouse
|mAh:||An ampere-hour or amp-hour (Ah) is a unit of electric charge. mAh (milliampere-hour) is one-thousnadth of that. It is a technical term for how much electrical charge a particular battery will hold.|
Short for "malicious software," malware refers to software programs designed to damage or do other unwanted actions on a computer system. |
Common examples of malware include viruses, worms, trojan horses, and spyware. Viruses, for example, can cause havoc on a computer's hard drive by deleting files or directory information. Spyware can gather data from a user's system without the user knowing it. This can include anything from the Web pages a user visits to personal information, such as credit card numbers.
|Maximize:||Maximizing a window makes it larger. In Windows, a maximized window fills the entire screen, while on a Mac, it takes up only as much space as needed. The maximize button in Windows is located in the upper-right corner of the window, next to the close button. If you double-click the title bar, it will also maximize the window. On a Mac, the maximize button is three green button located next to the red and yellow buttons in the upper-left corner of the window.|
|Mbps:||Stands for "Megabits Per Second." One megabit is equal to one million bits or 1,000 kilobits. While "megabit" sounds similar to "megabyte," a megabit is roughly one eighth the size of a megabyte (since there are eight bits in a byte). Mbps is used to measure data transfer speeds of high bandwidth connections, such as Ethernet and cable modems.|
A megapixel is one million pixels. It is commonly used to describe the resolution of digital cameras. For example, a 7.2 megapixel camera is capable of capturing roughly 7,200,000 pixels. The higher the megapixel number, the more detail the camera can capture. Therefore, the megapixel count is a significant specification to look for when buying a digital camera.|
A camera's megapixel number is calculated by multiplying the number of vertical pixels by the number of horizontal pixels captured by the camera's sensor, or CCD. For example, the original Canon Digital Rebel captures 2048 vertical by 3072 horizontal pixels, for a total of 6,291,456 pixels (2048 x 3072). Therefore, it is estimated to be a 6.3 megapixel camera. The Sony T10 captures 3072 x 2304 pixels, totaling 7,077,888, which makes it a 7.2 megapixel camera (because not all the pixels are used).
|Memory:||While memory can refer to any medium of data storage, it usually refers to RAM, or random access memory. When your computer boots up, it loads the operating system into its memory, or RAM. This allows your computer to access system functions, such as handling mouse clicks and keystrokes, since the event handlers are all loaded into RAM. Whenever you open a program, the interface and functions used by that program are also loaded into RAM.|
A menu bar is a horizontal strip that contains lists of available menus for a certain program. In Windows programs, the menu bar resides at the top of each open window, while on the Mac, the menu bar is always fixed on the top of the screen. Despite this major difference, the menu bar serves the same purpose on each platform.|
Nearly all programs have a menu bar as part of their user interface. It includes menu items and options specific to the particular program. Most menu bars have the the standard File, Edit, and View menus listed first. The File menu includes options such as Save and Open File..., the Edit menu has items such as Undo, Copy, Paste, and Select All, while in the View menu you'll find viewing options such as changing the layout of open windows. Word processing programs, such as Microsoft Word, also include menu options such as Insert, Format, and Font which you will most likely not find in a Web browser's menu bar. But a Web browser may contain menu options such as History and Bookmarks, which you will not find in a word processing program.
|MHL:||Mobile High-Definition Link (MHL) is an industry standard for a mobile audio/video interface that allows consumers to connect mobile phones, tablets, and other portable consumer electronics (CE) devices to high-definition televisions (HDTVs) and audio receivers. The MHL 3.0 standard supports up to 4K (Ultra HD) high-definition (HD) video and 7.1 surround-sound audio, including TrueHD and DTS-HD, while simultaneously charging the connected device. MHL-enabled products include adapters, automotive accessories, AV receivers, Blu-ray Disc players, cables, DTVs, media sticks, monitors, projectors, smartphones, tablets, TV accessories, and more.|
Stands for "Musical Instrument Digital Interface." It is a connectivity standard that musicians use to hook together musical instruments (such as keyboards and synthesizers) and computer equipment. Using MIDI, a musician can easily create and edit digital music tracks. The MIDI system records the notes played, the length of the notes, the dynamics (volume alterations), the tempo, the instrument being played, and hundreds of other parameters, called control changes.|
Because MIDI records each note digitally, editing a track of MIDI music is much easier and more accurate than editing a track of audio. The musician can change the notes, dynamics, tempo, and even the instrument being played with the click of button. Also, MIDI files are basically text documents, so they take up very little disk space. The only catch is that you need MIDI-compatible hardware or software to record and playback MIDI files.
Minimizing a window temporarily hides it from view without closing it. In Windows, a button for the minimized window is added to the taskbar. In Mac OS X, a small icon for the window is added to the dock. Clicking the window's button or icon will reopen the window. You can then click the maximize button to increase the window's size.|
To minimize a window in Windows, click the button with a horizontal line icon in the upper-right corner of a window. In Mac OS X, click the yellow button in the upper-left corner of the window or double-click the title bar.
|Modem:||The word modem is actually short for Modulator/Demodulator. A modem is a communications device that can be either internal or external to your computer. It allows one computer to connect another computer and transfer data over telephone lines. The original dial-up modems are becoming obsolete because of their slow speeds and are being replaced by the much faster cable and DSL modems.|
|Monitor:||The term "monitor" is often used synonymously with "computer screen" or "display." The monitor displays the computer's user interface and open programs, allowing the user to interact with the computer, typically using the keyboard and mouse.|
|Motherboard:||The motherboard is the main circuit board of your computer and is also known as the mainboard or logic board. If you ever open your computer, the biggest piece of silicon you see is the motherboard. Attached to the motherboard, you'll find the CPU, ROM, memory RAM expansion slots, PCI slots, and USB ports. It also includes controllers for devices like the hard drive, DVD drive, keyboard, and mouse. Basically, the motherboard is what makes everything in your computer work together.|
|Mouse:||A mouse, along with the keyboard, is one of the two main input devices used by computers. It is a small handheld device that tracks the user's motion and is used for moving the cursor on the screen. It also has buttons that are used for clicking and right-clicking objects.|
