A code which uses more bits for each character then what is necessary is known as

Gray code

Mnemonics

Hollerith code

Redundant code

Correct Answer : Redundant code

A code which uses more bits for each character then what is necessary is known as Redundant code.

In computer programming, redundant code is source code or compiled code in a computer program that is unnecessary, such as: recomputing a value that has previously been calculated and is still available, code that is never executed (known as unreachable code), code which is executed but has no external effect. A NOP instruction might be considered to be redundant code that has been explicitly inserted to pad out the instruction stream or introduce a time delay.

An error-correcting code (ECC) or forward error correction (FEC) code is a process of adding redundant data, or parity data, to a message, such that it can be recovered by a receiver even when a number of errors (up to the capability of the code being used) were introduced, either during the process of transmission,etc,..

A menu-driven operating system is one which allows you to pick up from the menu of choices it displays on the screen. What is the name given to the images which are used in such image oriented menus?

Figure

Icon

Symbol

None of the above

Correct Answer : Icon

A menu-driven operating system is one which allows you to pick up from the menu of choices it displays on the screen. Icon is the name given to the images which are used in such image oriented menus.

Menu Driven Interface. This type of interface lets you interact with a computer or device by working your way through a series of screens or menus. Think about your iPod or mobile phone, they both use a menu driven interface. You are presented with a menu, you make a choice and then the next menu appears on the screen.

In computing, an icon is a pictogram or ideogram displayed on a computer screen in order to help the user navigate a computer system. The icon itself is a quickly comprehensible symbol of a software tool, function, or a data file, accessible on the system and is more like a traffic sign than a detailed illustration of the actual entity it represents. It can serve as an electronic hyperlink or file shortcut to access the program or data. The user can activate an icon using a mouse, pointer, finger, or recently voice commands.
