Computer Science MCQ for Gate Exam

Explanation: This question asks you to identify which option does not function as a device that sends data into a Computer system. Input devices are responsible for capturing user data or signals and transmitting them to the Computer for processing. Common examples include keyboards, scanners, and voice recognition systems, all of which convert physical or analog input into digital form.

To approach this, first recall that input devices always feed data into the system, while output devices present processed information to the user. Some devices may seem similar in function but differ in direction of data flow. For example, scanners and OCR systems capture printed text and convert it into digital data, while voice recognition converts spoken words into machine-readable form.

The key is to distinguish whether the device sends data into the system or receives data from it. Any device designed to display, store, or output processed information rather than capture raw input would not fall under input devices.

Think of input devices like a microphone or camera—they collect information from the outside world. In contrast, devices that present results behave more like speakers or screens.

In summary, identifying the correct option depends on understanding the direction of data flow—whether the device feeds information into the system or outputs it after processing.

Explanation: This question focuses on estimating the precision of floating-point numbers when stored using a fixed number of bits in a Computer system. Floating-point representation divides memory into parts for sign, exponent, and mantissa, which together determine how accurately a number can be stored.

To analyze this, consider that two 16-bit words provide a total of 32 bits. These bits are distributed among different components of the floating-point format, with a significant portion allocated to the mantissa. The mantissa determines the number of significant digits that can be accurately represented. The more bits assigned to it, the higher the precision.

In practical terms, each binary bit roughly contributes to decimal precision. However, due to the structure of floating-point representation, not all bits directly translate into usable decimal digits. Typically, a 32-bit floating-point system provides a moderate level of precision, enough for many scientific and engineering calculations but not extremely high accuracy.

An analogy would be writing numbers with limited digits on a calculator display—more digits allow finer detail, while fewer digits cause rounding. Similarly, the bit allocation limits how precise the stored value can be.

Overall, the accuracy depends on how many bits are effectively used for representing significant digits within the given word size.
