 • data put in during manufacture

 • data can be changed.

 

a.     RAM-  volatile,  stores the program being worked on,                   

                  data can be changed.

b.     ROM – Non volatile, stores the start-up program, data    

                put in during manufacture

 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...

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...
