A multimedia tutor can provide multiple numbers of challenges to the student to stimulate his interest in a topic. The instruction provided by pedagogue have moved beyond providing only button level control to intelligent simulations, dynamic creation of links, composition and collaboration and system testing of the user interactions.
Communication Technology and Multimedia Services - The advancement of high computing abilities, communication ways and relevant standards has started the beginning of an era where you will be provided with multimedia facilities at home. These services may include: Basic Television Services.
Memory and Storage Devices - You need memory for storing various files used during production, original audio and video clips, edited pieces and final mined pieces.
You also need memory for backup of your project files. Primary Memory - Primary memory holds only those data and instructions on which computer is currently working. It has limited capacity and data gets lost when power is switched off. It is generally made up of semiconductor device.
These memories are not as fast as registers. The data and instructions required to be processed earlier reside in main memory. It acts as a buffer between the CPU and main memory. It is used to hold those parts of data and program which are most frequently used by CPU.
The parts of data and programs are transferred from disk to cache memory by operating system, from where CPU can access them. Secondary Memory: This type of memory is also known as external memory or non-volatile. It is slower than main memory. CPU directly does not access these memories; instead they are accessed via input-output routines. Contents of secondary memories are first transferred to main memory and then CPU can access it. Input Devices - Following are the various types of input devices which are used in multimedia systems.
Keyboard - Most common and very popular input device is keyboard. The keyboard helps in inputting the data to the computer. The layout of the keyboard is like that of traditional typewriter, although there are some additional keys provided for performing some additional functions. The keys are following: Sr.
Keys Description 1 Typing Keys These keys include the letter keys A-Z and digits keys which generally give same layout as that of typewriters. Generally, it consists of a set of 17 keys that are laid out in the same configuration used by most adding machine and calculators. These are arranged in a row along the top of the keyboard. Each function key has unique meaning and is used for some specific purpose.
It includes four directional arrow key. Mouse - Mouse is most popular Pointing device. It is a very famous cursor-control device. It is a small palm size box with a round ball at its base which senses the movement of mouse and sends corresponding signals to CPU on pressing the buttons.
Generally, it has two buttons called left and right button and scroll bar is present at the mid. Mouse can be used to control the position of cursor on screen, but it cannot be used to enter text into the computer.
Joystick - Joystick is also a pointing device, which is used to move cursor position on a monitor screen. It is a stick having a spherical ball at its both lower and upper ends.
The lower spherical ball moves in a socket. The joystick can be moved in all four directions. The function of joystick is similar to that of a mouse.
Light Pen - Light pen is a pointing device, which is similar to a pen. It is used to select a displayed menu item or draw pictures on the monitor screen.
It consists of a photocell and an optical system placed in a small tube. When light pen's tip is moved over the monitor screen and pen button is pressed, its photocell sensing element detects the screen location and sends the corresponding signal to the CPU. Track Ball - Track ball is an input device that is mostly used in notebook or laptop computer, instead of a mouse. This is a ball, which is half inserted and by moving fingers on ball, pointer can be moved. Since the whole device is not moved, a track ball requires less space than a mouse.
A track ball comes in various shapes like a ball, a button and a square. Scanner - Scanner is an input device, which works more like a photocopy machine. It is used when some information is available on a paper and it is to be transferred to the hard disc of the computer for further manipulation.
Scanner captures images from the source which are then converted into the digital form that can be stored on the disc. These images can be edited before they are printed.
Digitizer - Digitizer is an input device, which converts analog information into a digital form.
