Because of their reduced size, the screens on mobile devices are small, but usually are in colour. Popular types of mobile devices are smartphones and PDAs, e-book readers, handheld computers, portable media players, and digital cameras.
Smart Phones and PDAs Offering the convenience of one-handed operation, a smart phone is an Internet enabled phone that usually also provides personal information management functions such as a calendar, an appointment book, an address book, a calculator, and a notepad.
In addition to basic phone capabilities, a smart phone allows you to send and receive e-mail messages and access the Web usually for an additional fee. Some smart phones communicate wirelessly with other devices or computers. Many also function as a portable media player and include built-in digital cameras so that you can share photos or videos with others as soon as you capture the image. Many smart phones also offer a variety of application software such as word processing, spreadsheet, and games, and the capability of conducting live video conferences.
Others have a built-in mini keyboard on the front of the phone or a keyboard that slides in and out from behind the phone. Some have touch screens, where you press objects on the screen to make selections and enter text through an on-screen keyboard. Others include a stylus, which is similar to a digital pen but smaller and has less functionality. Types of messages users send with smart phones include text messages, instant messages, picture messages, and video messages. A phone that can send picture messages often is called a camera phone.
A phone that can send video messages often is called a video phone. A PDA personal digital assistant , which often looks like a smart phone, provides personal information management functions such as a calendar, an appointment book, an address book, a calculator, and a notepad. A PDA differs from a smart phone in that it usually does not provide phone capabilities and may not be Internet-enabled, support voice input, have a built-in camera, or function as a portable media player.
As smart phones and PDAs continue a trend of convergence, it is becoming increasingly difficult to differentiate between the two devices. This has led some manufacturers to refer to PDAs and smart phones simply as handhelds.
E-Book Readers An e-book reader short for electronic book reader , or e-reader, is a handheld device that is used primarily for reading e-books. In addition to books, users typically can purchase and read other forms of digital media such as newspapers and magazines.
Most e-book readers have a touch screen and are Internet-enabled. These devices usually are smaller than tablet computers but larger than smart phones.
Many handheld computers communicate wirelessly with other devices or computers and also include a digital pen or stylus for input. Some handheld computers have miniature or specialized keyboards. Many handheld computers are industry-specific and serve the needs of mobile employees, such as meter readers and parcel delivery people, whose jobs require them to move from place to place.
Game Consoles A game console is a mobile computing device designed for single-player or multi-player video games.
Weighing on average between two and nine pounds, the compact size of game consoles makes them easy to use at home, in the car, in a hotel, or any location that has an electrical outlet. A handheld game console is small enough to fit in one hand, making it more portable than the standard game console. With the handheld game console, the controls screen, and speakers are built into the device.
Because of their reduced size, the screens are small — three to four inches. Some models use cartridges to store games; others use a memory card or a miniature optical disc. Many handheld game consoles can communicate wirelessly with other similar consoles for multiplayer gaming. Servers can support from two to several thousand connected computers at the same time.
In many cases, one server accesses data, information, and programs on another server. In other cases, people use personal computers or terminals to access data, information, and programs on a server. A terminal is a device with a monitor, keyboard, and memory. Mainframes store tremendous amounts of data, instructions, and information.
Most major corporations use mainframes for business activities. With mainframes, enterprises are able to bill millions of customers, prepare payroll for thousands of employees, and manage thousands of items in inventory. One study reported that mainframes process more than 83 percent of transactions around the world.
Mainframes also can act as servers in a network environment. Servers and other mainframes can access data and information from a mainframe. People also can access programs on the mainframe using terminals or personal computers. The fastest supercomputers are capable of processing more than one quadrillion instructions in a single second.
With weights that exceed tons, these computers can store more than 20, times the data and information of an average desktop computer. Applications requiring complex, sophisticated mathematical calculations use supercomputers. Large-scale simulations and applications in medicine, aerospace, automotive design, online banking, weather forecasting, nuclear energy research, and petroleum exploration use a supercomputer. Embedded computers are everywhere — at home, in your car, and at work.
The following list identifies a variety of everyday products that contain embedded computers. Because embedded computers are components in larger products, they usually are small and have limited hardware. These computers perform various functions, depending on the requirements of the product in which they reside.
Embedded computers in printers, for example, monitor the amount of paper in the tray; check the ink or toner level, signal if a paper jam has occurred, and so on. Any part that we can see or touch is the hard ware. Display Unit, printer etc. So, what else is required? It requires a set of instructions that tells the computer what is to be done with the input data. In computer terminology, this set of instructions is called a program and one or more programs are termed as software.
Software used for computers may be of different types. The computer understands only machine language i. The software which does this translation is known as the system software.
Examples of system software are compilers and interpreters. Some are linked by expansion cards in expansion slots on the motherboard or connected directly on the ports via a cable attached on them. It has additional keys to handle special functions required by a computer.
Alphanumeric keys Comprises of alphabets A-Z , numbers and other characters. Special keys They perform specific functions. The Shift key when pressed with another key; alters the meaning of any alphanumeric key for e. Ctrl, Alt and Del pressed together restarts the system. The Esc key is generally used to return to the previous menu or quit a program.
The Cursor is a symbol displayed on the screen at the position where text or graphics will be inserted or deleted. The Cursor movement keys move the cursor on the screen. The Num-Lock is used to activate the numeric keys on the Numeric keypad. The Print Screen is used to print whatever is displayed on the screen. Enter or Return is used to communicate the end of an instruction or data being keyed in through the keyboard. Caps lock is used for keying upper case alphabets.
Backspace is used to erase the character to the left of the cursor position. The Function keys are used to perform a set of operations using a single keystroke. The function keys can be defined as special purpose keys.
In most of the software, pressing the F1 key will take you to the help feature. Other than these keys, 3 status indicators are present on the keyboard. There are two type of keyboard. Standard keyboard and Enhanced keyboard.
A mouse may have one, two or three buttons. The function each button depends on the program. Clicking the mouse results in selecting an option. Positioning a cursor with the mouse is easier for non-typists than pressing various key combinations. With an appropriate software, a mouse can also be used to draw pictures. The Computer mouse is of three types and two classifications.
SCANNER There are a number of situations when some information picture or text is available on paper and is needed on the computer disk for further manipulation. A scanner is used for this purpose. A scanner scans an image and transforms it into graphics. These can be edited, manipulated and combined, and then printed. Scanners are used to reproduce photographs on the computer screen.
These can be employed in training programs and in desktop publishing. Types of scanner a Flat-bed scanner or desktop scanner b Optic scanner, looks like a camera c Hand held scanner PRINTER In order to get a copy of the output for later reference, you would require a printer. Printers are capable of printing at a very high speed. Two commonly used printers are the dot-matrix printer and the laser printer.
Printers are classified on the basis of a number of parameters like, the mechanism used for printing, speed of printing, quality of output, direction of printing, and the kind of interface they have with the computer.
Printers can be broadly classified as impact and non-impact printers. Let us understand this in detail. Impact Printers Impact printers work like typewriters. The characters are printed by striking the paper i. Impact printers can again be classified as Character printers and Line printers. Character Printers Character printers print one character at a time.
Examples of character printers are. In a DMP, tiny hammers or pins strike the ribbon to produce the desired characters. The print head consists of 9x7 arrays of pins. Characters to be printed are sent one at a time to the printer. The characters printed are a series of dots. Dot- matrix printers are inexpensive but noisy.
They can print both text and graphics. They can print in any language without additional hardware change. They can also be made to print in colour by changing ribbons.
