    1.I believe inheritance promotes code reuse because similar methods can be placed in an abstract base class such that the similar methods do not have to be identically implemented within multiple children classes. For example, if you have three kinds of shapes, and each shape's method "getName" simply returns a data member '_name', then why re-implement this method in each of the child classes when it can be implemented once in the abstract base class "shape".

    CD ROM, stands for Compact Disc Read Only Memory, it is a type of storing data that goes up to 1 GB. It is an optical disk that has the capacity to store data, music files, video files etc. A single one has the average capacity to store the memory of about 700 floppy disk, which is equal to 3000,000 text pages. Once it is filled up with data, new data cannot be entered on it. First of all it was designed to store only the music and video files, but later this format has also been adapted to store the binary data of the computer. They are particularly used to distribute the computer software that can include, games, multimedia application etc.

    Y NECESSARY The disc of the CD ROM is 1.2 mm thick and has a thin layer of aluminum that makes a reflective surface. They are round in size and have a hole in the middle so that it can fit in easily. To read a CD you need a ROM player; almost all the player comes in a standard size and format, so it is very easy to load any type of these in your player. They are very much portable and can store all the information that requires a large amount of space capacity. When you buy a computer, it must be compatible with a CD ROM, or else you will not be able to install all the required programming to it. It has also become a very important source of application to provide video and audio systems to your PC

    1: Inheritance I pretty sure it's inheritance not polymorphism. 2: Yush ROM is needed! ROM is a set of instructions hard-coded into a computer system that cannot be changed. (eg. BIOS) Without ROM = No BIOS. 3: "Data inconsistency is likely to occur when there is data redundancy. Data redundancy occurs when the data file/database file contains redundant - unnecessarily duplicated - data" Source: http://wiki.answers.com/Q/What_is_data_inconsistency 4: A digitizer convert analog signals to digital signals. 5: Correct. 6: I believe it's plotters too. 7: "In the context of iostreams, writers often will refer to as << and >> as the 'put-to'." So I know 7 is correct. 8: CD-ROMs

    ROM tell the computer tells the rest of the system how to boot up, operate, calculate things, and then shut down when you're through. Without ROM you could not install and Operating System... Not even a BIOS... Let's say there is no ROM and you click the power button. The computer would not boot on because there is no ROM to tell the machine what to do.

    The property of C++ which helps in code reusability is inheritance... With inheritance once a base class is written and debugged, it can be used in various situations without redefining and rewriting it. Thus making the answer to be inheritance. Inheritance: http://oscience.info/computing-technology/inheritance-in-c/ Polymorphism: http://oscience.info/computing-technology/computer-programming/c/polymorphism/ @hba a computer in the time of today could actually create another computer. In fact back in 2003 a Chinese company made a robot to build copy of it's self without human help. And the robot successful did.
