19. Reena is using the keyboard to type a letter. How is the
computer able to display what she is typing on the monitor?
Reena interacts with the computer using akeyboard. The electrical signals for thealphabets typed on a keyboard are convertedto binary digits (binary
system) and stored.
These signals correspond to binary code thatcan be processed by a digital computer.When the computer displays the data on amonitor or when data is to be printed, thebinary system is again converted to electricalsignals and then to characters that humanscan understand. The process is thenreversed, wherein the binary code istranslated into a form understandable by theuser. This is how input gets converted tooutput in a computer.

27. Answer the following in brief:
i. Differentiate between the main memory and the secondarymemory.
- Main memory orRAM
Secondary Memoryor Hard disk
RAM (RandomAccess Memory) isalso called mainmemory. RAM isused to store dataand instructionsthat are currentlybeing processed by a computer’s CPU.
Secondary storage isthe memory wherethe information is stored permanently,till it is explicitlydeleted.
Data is temporarilystored in the RAMtill it is saved to the hard disk. The
data
in RAM is
erased
when power isswitched off.
The data on harddisk and othersecondary storage devices
is not erased
even after switchingoff the computer.
Programs areexecuted usingRAM.
The hard disk storesmultiple types ofdata andapplications. Thedocuments andcontent that a usercreates and saves,the software to

28. How do the various components of a computer receive
power?
The power supply unit in a computerconverts the power from the wall outlet(usually AC) to the type of power needed bythe computer (usually DC). The power supply unit sends power throughthe cables to the motherboard and othercomponents. The power cable from a walloutlet is connected to a socket in this unit.The power On button for a computer isusually available on the front panel of theCPU. For a laptop, it is usually availableabove the keyboard.

29. What are the functions of the motherboard in a computer?
The motherboard connects directly orindirectly to every part of the computer.Main function of the motherboard is to hold the computer’s
processor and let everything
else connect to it. The motherboard is the computer’s m
ain
circuit board. It is a thin plate that holds theCPU (Central Processing Unit), memory,connectors for the hard drive and opticaldrives, as well as various external ports andperipherals.A port is connected from inside to expansioncards which are plugged into themotherboard and are connected to othercomponents by cables which are long, flatbands that contain electrical wiring. Theports are controlled through the expansioncards.

Basic input output system (BIOS) is the firstsoftware that runs on a computer whenpower is switched on.First task of BIOS is to identify and initializedevices such as the display card, keyboard,mouse, hard disk, CD/DVD drive and otherhardware.Next task of the BIOS is to load the operatingsystem(OS) software (that is stored on a harddisk or a CD).BIOS gives control of the computer to the OS.This process is known as booting.

The OperatingSystem isresponsible formanaging the computer’s hardware andsoftware resources.It controls thememory neededfor computerprocesses, managesdisk space, controlsperipheral devices,and manages usercommunicationwith the computer.
The mostimportant role of BIOS
is to load
the operatingsystem (OS).When you turnon yourcomputer, theCPU needsinstructions tolocate theoperating systemin the hard disk.The
BIOS
provides thoseinstructions.
Actions from userlogin to applicationexecution, input,output, processingand controllingdevices are handledby the OS.

47. What are the advantages of taking a backup? In which situations can
you take a backup? What are the different devices you will use totake a backup?
Making a copy of a document or information thatyou create on the computer, is called taking abackup. Backup of content
(documents,
paintings, reports and so on.) that you create isimportant. This ensures that even if one devicefails, you have a copy of the content and canaccess it using another computer. Backups can be taken on CD/DVD, pen drive, SDcard, a removable ha
rd disk, or another
computer to which you have access. The storagecapacity of these devices is usually not as muchas a hard disk drive. These devices are calledremovable storage devices. These can beremoved from the computer and carriedwherever required. (The hard disk can also beremoved sometimes.)We can also mail a copy to ourselves or save it onan online drive such as Google Drive. This is agood option when you have Internet
