A plotter is a computer printing device for printing vector graphics. In the past, plotters were widely used in applications such as computer-aided design, though they have generally been replaced with wide-format conventional printers. It is now commonplace to refer to such wide-format printers as "plotters," even though they technically aren't. Plotter produces best quality graphics output. 

AT Computers

Computer having 80286, 80386, 80486, Pentium and the later processors are AT Computers. There were XT computers with 8080 and 8088 processors. Personal System/2 or PS/2 was developed by IBM to capture the PC market by introducing advanced propritary architecture. However, its memory module, keyboard/mouse port etc. became a defacto standard in later computers.

Sequential Processing

Sequential processing is a way of doing jobs where each job is done in serial fashion. Some application are sequential by nature such as playing songs or video. You can't jump randomely to any position and play. For example lets take three tasks - calculate total, percentage and division. You should first calculate total and use it in percentage and use the result to determine division. These three tasks are to be done sequentially. Similarly, processing of grades or payroll processing both have to go through sequential processing.


Processing is called to something where we make some modification to the given data either by calculating or by arranging or ordering or anything that would produce the result by manipulating the given data. So, calculating, arranging, manupulating are processing taks. Data collection (gathering) does not involve any sort of converting one data into other form, so it is not processing.


Software are the applications or computer programs that runs the hardware and perform required user jobs. Software enhances the capability of hardware, means it can make a computer do what it was not doing earlier. For example after you install a new software, your computer is capable to perform a new job. However, software can't increase speed of CPU or space of RAM etc.

Old Name of IBM

The giant computer manufacturing company IBM was named so in 1924. Till then, it was known as Computing-Tabulating-Recording since 1911. See the logo more of CTR in IBM Page.


Sorting is the task of arranging data in required order - ascending or descending by numbers or alphabets.
