ii. This part sends signals to other parts of the computer to tell them what

       to do.

           a. Keyboard      b. Mouse      c. Hard disk      d. CPU

iii. This memory is for short term storage and is lost when the computer      

       is turned off.

           a. ROM     b. RAM     c. Hard disk     d. CPU

iv. This part allows the user to hear information from the computer.

           a. Monitor      b. Software     c. Input     d. Speaker

 v. Another name for all the parts of a computer.

           a. Monitor     b. Software     c. Process     d. Hardware

 

Q2. Fill in the blanks-

          i. The binary system uses the symbols   0 and 1.

          ii. A unit of eight bit memory cell groups is called a…1 byte.

          iii. RAM stands for…Random access memory.

          iv. A KB in computer terminology is equal to …1024.bytes.

          v. Internal storage is also called main memory.

Q3. What are the two types of computer memory?

Ans3. Primary memory and Secondary memory.

 

Q4. Name any four input devices?

Ans4. Mouse, Keyboard, microphone, scanner

 

Q5. What is the function of memory? What are its measuring units?

Ans5. The memory that holds data and instructions during processing. It  

           is temporary memory. While secondary memory can store data or

           files for later use i.e. permanently. Bit, byte, kb, mb, gb etc. are

           its measuring units.

 

Q6. Describe types of hardware used for output. Name two most common output devices.

Ans6. Output devices are responsible for producing the output in user

           readable form. Some common hardware that

           are used for output are monitor, printer, speaker, plotter etc.

 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...

M.S. WORD Topic- Margin

Image
 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...
