1. Iftikhar Ahmad Roll No : 13 ::Topic:: Introduction Refresh CRT Random–Scan and Raster Scan System Graphics Monitor and Workstation Input Devices 30 April 2015 1

2. Graphic Monitors Graphics Monitor: The name itself giving some idea that, Monitor which is capable of displaying “Graphics”. Most graphics monitors today operate as raster scan displays. So Monitors which are capable of showing and supporting Graphics mode along with the Text modes . 30 April 2015 2

3. A high-definition graphics monitor used in applications such as air traffic control, medical imaging, and CAD. 30 April 2015 3

4. Graphic monitors who can display pictures on its screen, of course it acts like an output device. The monitors which support the following Graphic applications are said to be Graphic Monitors : The Graphics Applications include:- A): Animation Software’s B): CAD Software’s C): Drawing programs D): Paint Application programs E): Presentation Graphics Software’s (Excel likewise, creating pie and bar charts) F): Desktop publishing (MS Office, Share points, Document managements) 30 April 2015 4

5. Workstations Workstation: Workstation is also a computer which varies generally with other General Computers. A workstation is a special computer designed for technical or scientific applications. Intended primarily to be used by one person at a time, they are commonly connected to a local area network and run multi-user operating systems . 30 April 2015 5

6. Workstations were optimized for the visualization and manipulation of different types of complex data such as 3D mechanical design, engineering simulation , animation and rendering of images. Because these Workstations need good operating power of computer . They must be able to support high power i.e. it must sustain good graphic capabilities. 30 April 2015 6

7. Animation 30 April 2015 7 3D Car model

8. These kind of computers  comes with the following specifications. Unlike normal general computers they consists of: A):Minimum of 64 Megabytes of RAM & high processor B):Very good Resolution Graphics screen C):High and Large Screen D):GUI Graphical User Interface E):Mass storage Device like Disk Drive(optional) F):Built-in Network Support and many factors 30 April 2015 8

9. Workstation: A computer that is used to power applications such as graphic art, 3-D design, Video Editing, or other intensive software. 30 April 2015 9

10. We may also notice that, some of the workstations do not have any disk drives in it. So these kind of disk drives are called as Diskless workstation . Workstations took place of and they lie between Personal computer and minicomputers as far as Computing power is concerned . These can be used as both types such as stand system (which only consists of one) and Local area network. So basically in this LAN kind, workstations are typically connected together one and other. 30 April 2015 10

11. Many graphics workstations are configured with two monitors. One monitor can be used to show all features of an object or scene, while the second monitor displays the detail in some part of the picture. Another use for dual-monitor systems is to view a picture on one monitor and display graphics options (menus) for manipulating the picture components on the other monitor. 30 April 2015 11

12. question arises? Is there any difference b/w Workstation and Server??? 30 April 2015 12

13. A server is a computer whose purpose is to handle requests for data from other computers. Website servers provide visitors' computers with the data necessary to display its Web pages; servers on your company's local network provide files to your employees' computers. Servers can host applications, but people access that application through their own computers. Employees do not sit down at a server to do their work, unless their work is maintaining the server. A workstation is a personal computer that is used for high end applications such as graphic design, video editing, CAD, 3-D design, or other CPU and RAM intensive programs. A workstation typically has a top of the line, fast processor, multiple hard drives, and a lot of RAM memory. A workstation may also have special audio, video, or processing cards for special editing work. A workstation is marketed by computer manufacturers to professional users, while the server is more of a utility device. 30 April 2015 13
