Typically, the motherboard contains slots  for the processor, BIOS, ROM chip, CMOS setup, mass  storage
                      interfaces, serial and parallel ports, expansion slots and all the controllers required for standard peripheral
                      devices like monitor, keyboard, disc drives, etc. The chips that are attached to the motherboard are known as
                      the ‘Motherboard Chipset’.
                   7.  What are the different kinds of expansion cards? Explain them.
                 Ans.  Network Interface Card (NIC): A network interface card is an expansion board that enables the exchange of
                      data between the computer and a network.  ICs are designed to operate in a specific type of network, such as
                      Ethernet or Token Ring. Modern NICs are manufactured to be integrated into PCI expansion slots.

                        Sound Card: A sound card is an expansion board that enables to produce sound as output that can be heard
                      through speakers or headphones. It is also used to record sound as input from a microphone that is connected
                      to the computer and to edit or mix sound stored on a disk. Most of the sound cards are manufactured to be
                      integrated into PCI expansion slots.

                        Graphics Card (Display Adaptor): A graphics card is an expansion board that helps us process & display
                      videos. Modern display adaptors contain memory, therefore, many times the RAM of a computer is not used for
                      storing the data. Availability of memory is a major factor in determining the screen resolution and colours that
                      can be displayed on the monitor. Graphic cards are manufactured to be integrated into PCI expansion slots.
                    .  Define Software.

                 Ans.  The computer can neither think nor work on its own. It has to be provided with a set of pre-defined instructions
                      which are written in a computer language. Such sets of instructions are known as ‘Programs’. A set of organized
                      programs meant for a specific purpose is known as  Software . Software is an intangible part of a computer.

                   9.  What are the key skills one should possess to use ICT?                          [CBSE Handbook]
                 Ans.  Basic ICT skills that one should possess to use ICT are:

                        knowing how to operate computers
                        knowing how to use the Internet to browse for collecting, storing and disseminating information

                  10.  What are the advantages of using ICT tools in Education?
                 Ans.  Access to Remote Learning: With the help of ICT, a wealth of learning material on almost every topic can be
                      accessed from anywhere at any point in time & by an unlimited number of people.
                       Use of Media: Images and pictures can easily be used in teaching and improving the retentive memory of
                      students by recognizing, relating and composing the things with real-life objects.
                       Easier Explanation: Teachers can easily demonstrate to explain complex instructions and ensure students’
                      understanding.

                       Interaction: The classes can be made more interactive and the lessons become more enjoyable.
                       Environmental Saving: Natural resources are saved as learners don’t need to travel long distances to attend
                      coaching or classes. It also saves time, effort and money.

              B.  Application based questions:                                                          L if e Sk il l s  &  V a l ues

                   1.  If you have filled-out an admission form for a college and need to send an email to the college authorities.
                      Which device will you use to send the form?

                 Ans.  You can scan it using the scanner and then e-mail it to the college instead of sending the actual form by post.
                      It  can be edited later.
