Computer output devices include monitors, graphic plotters, and printers. Monitors display information and come in CRT and flat panel varieties. Printers produce hard copies and are either impact printers that use physical contact or non-impact printers like laser and inkjet that do not. Impact printers include dot matrix and line printers while non-impact printers offer faster speeds and higher quality output.
The Output Devices of computer system are electromagnetic devices or gadgets that accepts or acknowledge data or informations from computer system and translate and converts the data in human readable or intelligent form. Generally output can be obtained and acquire mainly in two distinct and different ways Softcopy and Hardcopy.At the point when handled data or information is stored in computer memory is given to an output unit then this processed or prepared data or information is displayed to user in such a way that they can easily read
An output device is computer hardware that uses received data and commands from a computer in order to perform a task.

Input and Output Devices PPT by Aamir Saleem AnsariTech
An input device sends information to a computer system for processing, and an output device reproduces or displays the results of that processing. Depending on the interaction, a device can be both, referred to as an input/output or I/O device.
For example, as you can see in the top half of the image, a keyboard sends electrical signals, which are received by the computer (input). Those signals are then interpreted by the computer and displayed on the monitor as text (output). In the lower half of the image, the computer sends data to a printer, which will print the data onto a piece of paper (output).
An input device can send data to another device, but it cannot receive data from another device. Examples of an input device include a computer keyboard and mouse, which can send data (input) to the computer, but they cannot receive or reproduce information (output) from the computer.
An output device can receive data from another device, but it cannot send data to another device. Examples of an output device include a computer monitor, projector, and speakers, which can receive data (output) from the computer, but they cannot send information (input) to the computer.
Output devices translate information processed by the computer into a form that you the user can understand. View this slideshow to learn more about these devices.

Devices that output hard copy
An external hardware device responsible for taking computer data and generating a hard copy of that data. Printers are one of the most commonly used peripherals and they print text and still images on the paper.
Impact printers use a device to strike an inked ribbon, pressing ink from the ribbon onto the paper.
Non-impact printers use different methods to place ink (or another substance) on the page.
(1) DPI:
It is a measurement of printer’s resolution indicating how many ink dots can be placed by the printer in one square inch. The higher the DPI, the sharper is image. Image quality – Measured in dots per inch (dpi). Most printers produce 300 – 1200 dpi.
(2) Type of printer:
Each type of printer has its own capabilities of printing. Some types of printers produce high quality print while other produce low quality print.
(3) Print Mode:
The printing mode may also affect the quality. For example the draft mode increases the print rate but quality is reduced.
(4) Toner:
The quality and amount of toner also affects print quality.
In computers, a printer is a device that accepts text and graphic output from a computer and transfers the information to paper, usually to standard size sheets of paper. Printers are sometimes sold with computers, but more frequently are purchased separately. Printers vary in size, speed, sophistication, and cost. In general, more expensive printers are used for higher-resolution color printing. https://isotechline.com/

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
2. Computer - Output Devices
• Following are few of the important output devices which are used in a
computer.
• Monitors
• Graphic Plotter
• Printer
3. Monitors
• Monitors, commonly called as Visual Display Unit (VDU), are the main output
device of a computer. It forms images from tiny dots, called pixels that are arranged
in a rectangular form. The sharpness of the image depends upon the number of
pixels.
• There are two kinds of viewing screen used for monitors.
• Cathode-Ray Tube (CRT)
• Flat- Panel Display
• Cathode-Ray Tube (CRT) Monitor
• The CRT display is made up of small picture elements called pixels. The smaller
the pixels, the better the image clarity, or resolution. It takes more than one
illuminated pixel to form whole character, such as the letter ‘e’ in the word help.
• A finite number of characters can be displayed on a screen at once. The screen can
be divided into a series of character boxes - fixed location on the screen where a
standard character can be placed. Most screens are capable of displaying 80
characters of data horizontally and 25 lines vertically. There are some
disadvantages of CRT:
• Large in Size
• High power consumption
5. Flat-PanelDisplay Monitor
• The flat-panel display refers to a class of video devices that have reduced
volume, weight and power requirement in comparison to the CRT. You can
hang them on walls or wear them on your wrists. Current uses of flat-panel
displays include calculators, video games, monitors, laptop computer, graphics
display.
• The flat-panel display is divided into two categories:
• Emissive Displays - The emissive displays are devices that convert electrical
energy into light. Example are plasma panel and LED(Light-Emitting Diodes).
• Non-Emissive Displays - The Non-emissive displays use optical effects to
convert sunlight or light from some other source into graphics patterns.
Example is LCD(Liquid-Crystal Device)
7. Printers
• Printer is an output device, which is used to print information on paper.
• There are two types of printers:
• Impact Printers
• Non-Impact Printers
• Impact Printers
• The impact printers print the characters by striking them on the ribbon which is
then pressed on the paper.
• Characteristics of Impact Printers are the following:
• Very low consumable costs
• Very noisy
• Useful for bulk printing due to low cost
• There is physical contact with the paper to produce an image
• These printers are of two types
• Character printers
• Line printers
8. Printers
• Character Printers
• Character printers are the printers which print one character at a time.
• These are further divided into two types:
• Dot Matrix Printer(DMP)
• Daisy Wheel
• DOT MATRIX PRINTER
• In the market one of the most popular printers is Dot Matrix Printer. These printers
are popular because of their ease of printing and economical price. Each character
printed is in form of pattern of dots and head consists of a Matrix of Pins of size
(5*7, 7*9, 9*7 or 9*9) which come out to form a character that is why it is called
Dot Matrix Printer.
10. Printers
• Line Printers
• Line printers are the printers which print one line at a time
• These are of further two types
• Drum Printer
• Chain Printer
11. Printers
• DRUM PRINTER
• This printer is like a drum in shape so it is called drum printer. The surface
of drum is divided into number of tracks. Total tracks are equal to size of
paper i.e. for a paper width of 132 characters, drum will have 132 tracks. A
character set is embossed on track. The different character sets available in
the market are 48 character set, 64 and 96 characters set. One rotation of
drum prints one line. Drum printers are fast in speed and can print 300 to
2000 lines per minute.
• Advantages
• Very high speed
• Disadvantages
• Very expensive
• Characters fonts cannot be changed
• CHAIN PRINTER
• In this printer, chain of character sets are used so it is called Chain Printer.
A standard character set may have 48, 64, or 96 characters.
12. Printers
• Advantages
• Character fonts can easily be changed.
• Different languages can be used with the same printer.
• Disadvantages
• Noisy
13. Printers
• Non-impact Printers
• Non-impact printers print the characters without using ribbon. These printers print a
complete page at a time so they are also called as Page Printers.
• These printers are of two types
• Laser Printers
• Inkjet Printers
• Characteristics of Non-impact Printers
• Faster than impact printers.
• They are not noisy.
• High quality.
• Support many fonts and different character size.
14. Printers
• Laser Printers
• These are non-impact page printers. They use laser lights to produce the dots
needed to form the characters to be printed on a page.
• ADVANTAGES
• Very high speed
• Very high quality output
• Give good graphics quality
• Support many fonts and different character size
• DISADVANTAGES
• Expensive.
• Cannot be used to produce multiple copies of a document in a single printing.
15. Printers
• Inkjet Printers
• Inkjet printers are non-impact character printers based on a relatively new
technology. They print characters by spraying small drops of ink onto paper. Inkjet
printers produce high quality output with presentable features.
• They make less noise because no hammering is done and these have many styles of
printing modes available. Colour printing is also possible. Some models of Inkjet
printers can produce multiple copies of printing also.
• ADVANTAGES
• High quality printing
• More reliable
• DISADVANTAGES
• Expensive as cost per page is high
• Slow as compared to laser printer
