What is plotter and different types of plotter-computer world

 What is plotter and different types of plotter 

Plotter 

Plotter is used for an ideal output devices like engineering, city planner and others who need hard copy output of different size. We know that printers are used for graphics output but many engineers requires high quality output on large sheet. 

Two commonly used plotters are 

  1. Drum plotter
  2. Flatbed plotter
  3. Ink jet plotter

1. Drum plotter :

 in a drum plotter the paper on which the design is to be made is placed a the drum that can rotate in both clockwise and anticlockwise it produce vertical motion. The machine is also  consist of one or more pen holder connected to the drum surface. The pen can move left to right or right to left produce horizontal motion. The drum and pen move simultaneously to draw design and graphs on the sheet placed on the drum. 

2. Flatbed plotter :

 A flatbed plotter plot a design or graphs on a sheet of paper that is fixed over a flatbed table. In this type of plotter the paper does not move and the pen holding mechanism provide all type of motion to draw design and graphs. 

3. Ink jet plotter :

This device pushes beads of ink on the surface on which we are printing. Ink jet plotter is used by advertising agencies.

Single partition allocation, Multiple-partition allocation and Fixed Equal-size partitions in operating system-computer world

  Single partition allocation, Multiple-partition allocation and Fixed Equal-size partitions in operating system Single partition allocation In this scheme operating system is residing in law memory and user process are executing in higher memory. Advantages It is simple  It is easy to understand and use Disadvantages User job is limited to the size of available memory. It leads to poor Utilization of processor and memory. Multiple-partition allocation  It is the simplest method for allocating  memory is divided memory into several fixed size partitions. Fixed Equal-size partitions It divides the main memory Into equal number of fixed sized partitions, operating system occupies some fixed portion and remaining portion of main memory is available for user processes. Advantages It supports multi programming. A process whose size is less then or equal to the partitions size can be loaded into any available partition. Disadvantages If a program is big to fit in...

Difference between HTML and DHTML-computer world

     Difference between HTML and DHTML  HTML is a markup language, while DHTML is a collection of Technology.  DHTML creates dynamic web page, whereas HTML create static web page.  DHTML allow including small animations and dynamic menus in web pages but HTML is not able to do so.   HTML used events, methods, properties to insulate dynamism in HTML pages.   HTML is used to describe the web page but DHTML is a collection of JavaScript and style sheet in an HTML page. HTML sites will be show upon client side Technologies, while  DHTML site will be fast enough upon client side Technologies as most of entries are checked on browser itself and not waste time rendering to server for mistake.  HTML creates a plain web page without any style and scripts called as HTML. Whereas,  DHTML creates a page with HTML, CSS,DOM And scripts called as DHTML.  HTML cannot any server side code but XHTML may contain server side code.  ...

Distributed transaction model-oocomputerworld

  Distributed transaction model Distributed transaction model:- To access the various data items in a distributed system is usually e accomplished through transaction there are two type of transaction that we need to consider The local transaction The Global transaction    The local transaction:- The local transaction are those that access and update data is only one local database.  The global transaction:- global transaction are those that access and update data in several local database in the case of global transaction the task is more complicated since several nodes may be participating in execution the failure of a communication link connecting these nodes may result in erroneous computation.  System structure :- Each node has its oven local transaction manager whose function is to ensure those transaction that execute at that site. The various transaction manager corporate to execute global transaction. To understand how such a manager can be impl...
