Solutions

S1. Ans.(d)

Sol. Since static and dynamic images, high graphics, voice notes and songs are rich in properties, they occupy a lot of memory in the storage system of the computer. 

S2. Ans.(b)

Sol. Input devices are hardware components that allow you to enter data and instructions into a computer system. 

S3. Ans.(c)

Sol. HDMI is the most common one for connecting to TVs and also appears on many external monitors and projectors. Other ports for this purpose are DVI (Digital Visual Interface) and Display Port. Earlier there were VGA ports  (Video Graphics Array) .

S4. Ans.(d)

Sol. A motherboard is a part of the computer hardware that compensates the difference between the speeds of CPU and peripherals. 

S5. Ans.(d)

Sol. Super computers are designed for special purposes with specific inputs. For example, Super Computers are used for scientific, defence, or architectural purposes with specific instructions or input. 

S6. Ans.(c)

Sol. RAM is a hardware component that helps to start a computer system by booting, as it contains the startup instructions. 

S7. Ans.(b)

Sol. Flash drives are external storage media, not necessarily required to start a system, unless you are trying to reboot the system through a bootable flash drive. 

S8. Ans.(a)

Sol. A motherboard is that part of a CPU which coordinates all the activities of a computer system. Various types of hardware are attached on the motherboard to facilitate these activities.  

S9. Ans.(c)

Sol. A floppy disc is a storage device that has a very small storage capacity of only 1.44 MB. Due to small storage capacity and proneness to frequent damages floppy discs vanished from the market.  

S10. Ans.(d)

Sol. CDs and DVDs are used to write data on them. Even though compact, these devices can easily carry large volumes of data. They are Optical storage devices. 

S11. Ans.(b)

Sol. The power-on self-test (POST)routines are part of a device's pre-boot sequence and only once they complete successfully is the bootstrap loader code invoked to load an operating system.

S12. Ans.(d)

Sol. In a computer system, there are only three types of languages to perform different types of work on the computer, which are high level, low-level, and machine languages. 

S13. Ans.(a)

Sol. Hertz is a unit in which the speed of clock frequency of a microprocessor is measured. 

S14. Ans.(c)

Sol. A flash drive is plugged into a USB port. 

S15. Ans.(d)

Sol. Hard disc is a nonvolatile storage device, as the data that is saved on it is never lost on restart or sudden power break.
