Cbse, class 7, IT computer, unit 1 Ch.1 Types of Software System Software It is responsible for managing and controlling hardware resources so that other software and users can use the hardware effectively. Operating System: An Operating System (OS) is the most important and basic set of software required for a computer to function. It manages the hardware resources and provides some common services for the users. A general purpose computer must have an operating system to install and run other programs. Some of the basic tasks of an operating system are: · Receiving input from input devices and send output to output devices. Š · keeping track of files and directories on the hard disk and other storage devices Š · allocating memory to various programs and files Š · ensuring security by specifying user access rights · Some examples of operating systems are DOS, UNIX, Windows, LINUX, Ubuntu and Mac OS X.

Translates the program one statement at a time. 2. As it scans the code in one go, the errors (if any) are shown at the end together. Considering it scans code one line at a time, errors are shown line by line. 3. The main advantage of compilers is its execution time. Due to interpreters being slow in executing the object code, it is preferred less. 3. List and explain the function of any four utility software. · Antivirus utilities scan files for computer viruses and remove them. · Backup utilities are used to make a copy of all the information stored on a disk so that it can be restored in case of a disk failure. · Data compression utilities are used to compress files into a smaller size so that they occupy less disk space. Compressed files are also easier and faster to sen
