Printers convert electronic documents into physical form by transferring text and graphics onto paper. There are two main categories of printers: impact printers that use mechanisms like pins to strike ink onto paper, and non-impact printers that use other methods like inkjet or laser printing. When evaluating printers, considerations include image quality, speed, initial cost, and operating costs of supplies. Common printer types include dot matrix, inkjet, and laser printers that vary in performance and cost. Plotters are specialized printers used for vector graphics that work by moving pens across paper.
Output Device
Output devices such as monitors, printers, and speakers are discussed. Monitors can be CRT or TFT, with TFT being newer, smaller, and quieter than CRT but with potentially less quality. Printers include laser, inkjet, dot matrix, and plotters. Laser printers are fast and high quality but expensive, while inkjet printers are cheaper but slower. Dot matrix printers can make carbon copies but are low quality and loud. Plotters can print on large paper but are slow. Speakers help with using computers but can disturb others, while lights provide status signals.

Computer Output Devices
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.
Output devices
Monitors display computer output using pixels arranged on a screen. There are two main types of monitors - CRT monitors which are bulkier and use cathode ray tubes, and flat-panel displays like LCD which are thinner, lighter, and more power efficient. Printers produce hard copies of documents and come in two varieties - impact printers that use ink ribbons and are noisier, and non-impact printers like laser and inkjet that work silently without ribbons. Plotters are specialized printers used for technical drawings, with different types existing like drum, flatbed, and roller plotters.
Random scan displays and raster scan displays
Raster scan displays work by sweeping an electron beam across the screen in horizontal lines from top to bottom. As the beam moves, its intensity is turned on and off to illuminate pixels and form an image. The pixel values are stored in and retrieved from a refresh buffer or frame buffer. Random scan displays draw images using geometric primitives like points and lines based on mathematical equations, directing the electron beam only where needed. Raster scans have higher resolution but jagged lines, while random scans produce smooth lines but cannot display complex images. Both use a video controller and frame buffer in memory to control the display process.
Output devices
Output devices can be either hard copy or soft copy. Hard copy devices such as printers output data onto physical paper. Common printers are dot matrix, inkjet, and laser printers. Soft copy devices such as computer monitors output intangible visual or audio data that requires a computer to be viewed. Common soft copy devices are monitors, video projectors, and audio response systems.
scanners and plotters
Scanners are input devices that allow data entry from source documents directly by translating paper documents into electronic format. There are three main types of scanners: flatbed scanners which scan documents placed on a glass plate; hand-held scanners which are portable and dragged across documents; and optical mark readers which recognize pre-specified marks made by pencil or pen. Plotters are computer-controlled printers that produce high-precision graphic output and come in two varieties: drum plotters which use rotating drums and movable pens; and flatbed plotters which use stationary paper and moving pens.

THE SACRIFICE HOW PRO-PALESTINE PROTESTS STUDENTS ARE SACRIFICING TO CHANGE T...
The recent surge in pro-Palestine student activism has prompted significant responses from universities, ranging from negotiations and divestment commitments to increased transparency about investments in companies supporting the war on Gaza. This activism has led to the cessation of student encampments but also highlighted the substantial sacrifices made by students, including academic disruptions and personal risks. The primary drivers of these protests are poor university administration, lack of transparency, and inadequate communication between officials and students. This study examines the profound emotional, psychological, and professional impacts on students engaged in pro-Palestine protests, focusing on Generation Z's (Gen-Z) activism dynamics. This paper explores the significant sacrifices made by these students and even the professors supporting the pro-Palestine movement, with a focus on recent global movements. Through an in-depth analysis of printed and electronic media, the study examines the impacts of these sacrifices on the academic and personal lives of those involved. The paper highlights examples from various universities, demonstrating student activism's long-term and short-term effects, including disciplinary actions, social backlash, and career implications. The researchers also explore the broader implications of student sacrifices. The findings reveal that these sacrifices are driven by a profound commitment to justice and human rights, and are influenced by the increasing availability of information, peer interactions, and personal convictions. The study also discusses the broader implications of this activism, comparing it to historical precedents and assessing its potential to influence policy and public opinion. The emotional and psychological toll on student activists is significant, but their sense of purpose and community support mitigates some of these challenges. However, the researchers call for acknowledging the broader Impact of these sacrifices on the future global movement of FreePalestine.

This document provides an overview of wound healing, its functions, stages, mechanisms, factors affecting it, and complications.
A wound is a break in the integrity of the skin or tissues, which may be associated with disruption of the structure and function.
Healing is the body’s response to injury in an attempt to restore normal structure and functions.
Healing can occur in two ways: Regeneration and Repair
There are 4 phases of wound healing: hemostasis, inflammation, proliferation, and remodeling. This document also describes the mechanism of wound healing. Factors that affect healing include infection, uncontrolled diabetes, poor nutrition, age, anemia, the presence of foreign bodies, etc.
Complications of wound healing like infection, hyperpigmentation of scar, contractures, and keloid formation.
