Cbse, class 7, IT COMPUTER, united 1types of software

Cbse, class 7, IT COMPUTER, united 1types of software   2. How is an interpreter different from a compiler?   S.No. Compiler Interpreter 1. The compiler scans the whole program in one go. 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 compres...
