2INTRODUCTION TO COMPUTINGQuestion 2:Operating system: Operating system can be regarded as the most essential program, executed on anycomputer system. Operating system is essential for every computer system. With an operatingsystem, the computer is just a bare machine without any use. A computer cannot be used withoutthe combination of hardware and software. Only hardware and software alone cannot performthe programs that are used to be executed by the computer system. There should be effectivecommunication between the software and hardware in order to make the computer work.Operating systems are deployed to manage both the hardware and software and make effectivecommunication between them. The operating system performs basic task like processing inputfrom the keyboard and displaying it on the screen, keeping track of different files and directories,stored on different storage drives and it also controls different peripheral devices like mouse,printers. However, operating systems, used for larger systems, are more powerful and assignedwith greater responsibilities of managing several programs simultaneously and accurately. Network Operating System (NOS):NOS is basically an operating system for the computer, which helps in managingworkstation and personal computer. It is also used to manage the older terminal that is connectedwith the help of local area network, commonly known as LAN. NOS provides necessaryinterface to share file using printer, database and applications. It can manage the networkdirectory, security and other important aspects related to the network.

3INTRODUCTION TO COMPUTINGQuestion 3:Difference between Wide Area Network (WAN) and Local Area Network (LAN):Wide Area Network (WAN):WAN is networking technology used in telecommunication and computer networking.The network is extended to serve a large geographical area. The network helps to communicatewith devices that are far distant. Wide area networks need telecommunication circuits that aredesigned in leased fashion to make communication with devices. The network is deployed by government, educational institutes and businessorganizations to send and receive data over the network. This network is highly effective forbusiness organizations as it allows for communication with clients and other organizations,regardless of their location and distance. The internet can be considered as wide area network. Local Area Network (LAN):However , local area network , commonly referred to as LAN, is used to establishconnection between computers that are within short and limited distance. Many LANs makes useof the technologies related to wireless communication which are normally built in and used bySmartphones,tablet computersandlaptops. The concept of wireless network has become verypopular due to ease of use and simple installation technique.
