3. Which of the following is not a Hardware ?

(A) Processor chip

(B) Printer

(D) Java

Explanation:-Processor chip, Printer and Mouse are hardware while JAVA is a software. Java is a programming language originally developed by James Gosling at Sun Microsystems (which has since merged into Oracle Corporation) and released in 1995 as a core component of Sun Microsystems’ Java platform. The language derives much of its syntax from C and C++, but it has fewer low-level facilities than either of them

4. Which one of the following is a system software ?

(A) Database programs

(B) Word processors

(D) Compilers

(A) Silicon

(B) Lead

(D) Gold

Explanation:-An integrated circuit or monolithic integrated circuit (also referred to as an IC, a chip, or a microchip) is an electronic circuit on one small plate (“chip”) of semiconductor material, normally silicon.

8. To read a CD-ROM disc, you need a

(A) laser beam

(B) magnetic needle

(D) graphics card

Explanation:-Data is stored on the disc as a series of microscopic indentations. A laser is shone onto the reflective surface of the disc to read the pattern of pits and lands. Because the depth of the pits is approximately one-quarter to one-sixth of the wavelength of the laser light used to read the disc, the reflected beam’s phase is shifted in relation to the incoming beam, causing destructive interference and reducing the reflected beam’s intensity. This pattern of changing intensity of the reflected beam is converted into binary data

9. If you undergo a CAT scan then you have been subjected to

(A) a computer aided test

(B) a computerised axial topography

(D) a computerised axial tomography

Explanation:-A CT scan stands for Computed Tomography scan. It is also known as a CAT (Computer Axial Tomography) Scan. It is a medical imaging procedure that utilizes computer-processed X-rays to produce tomographic images or ‘slices’ of specific areas of the body
