c) Compiler
d) All of the above
ii. LCD stands for
a) Liquid crystal display
b) Light crystal display
c) Light color display
d) None of these
iii. This language processor converts a HLL program into machine language by converting and executing it line by line.
a) Assembler
b) Interpreter
c) Compiler
d) Operating system
iv. Which software takes control of computer system on startup?
a) Compiler
b) Operating System
c) Application software
d) All of these
v. The primary job of the operating system of a computer is to
a) Manage resources
b) be user friendly
c) Provide utilities
d) All of the above
2. What are the major components of a computer system?
Ans2. Major components of a computer system are:
1. Hardware
2. The Operating System
3. The Application program
4. The Humanware (users)
3. Name two popular web browsers.
Ans3. Google Chrome, Internet Explorer
4. What is operating system?
Ans4. An operating system is a program, which acts as an interface between a user
and the hardware (i.e. all computer resources) For eg. Windows 7, MS DOS etc.
5. What is the difference between an interpreter and a compiler?
Ans5. An interpreter converts an HLL program into machine language line by line and simultaneously executes the converted line. Also, interpreter does not proceed unless the error is rectified.
A compiler converts an HLL program in machine language in one go. If there are errors in the program, it gives the error list along with the line numbers.

 Computer Applications Class IX Basics of Operating Systems (Chap 4) Operating Systems- Shell and Kernel Operating system has broadly two components: Shell and Kernel. v The shell part is responsible for interacting with the users and v The kernel part is responsible for interacting with hardware. The shell act as the interpreter which does these things: i. Get the commands/instructions from the user. ii. Translate the received commands / instructions into the machine language. iii. Pass the translated command to the Kernel to get it done. The Kernel is the core part of an operating system. It functions at a basic level, communicating with the actual hardware and managing resources, such as CPU and the memory. It works as an interface between the user applications and the hardware. Functions of operating system broadly fall into three categories- Essential functions, monitoring functions and service functions. Essential functions ensure effective utilization of computer system reso...

 Computer Applications Class IX M. S. Word I (Chap 7) Worksheet 08 (chap 7) September 2020:- M. S. Word is WYSIWYG program. What you see is what you get program is the one that shows the document on screen, exactly the way it will on the print out. Word wrap- In M.S. Word, when a word does not fit on a line, it automatically flows to the beginning of the next line; this process is known as Word Wrap. Margin- The distance from the text to the paper’s edge is called Margin. The margins are of different types: 1. Left Margin- This is the distance between the text and the left edge of the paper. 2. Right Margin- This is the distance between the text and the right edge of the paper. 3. Top Margin- This is the distance between the text and the top edge of the paper. 4. Bottom Margin- This is the distance between the text and the bottom edge of the paper. Indent- The distance between text boundaries and page margins is called Indent. There are broadly three types of indents: 1. Positive i...
