Secondary storage saves data after the primary storage (RAM) saves it, providing permanent storage when power is turned off. Common secondary storage devices include hard drives, optical drives, and USB flash drives.
The hard drive is the computer's main storage device that permanently stores all data. It uses rapidly rotating disks coated with magnetic material to store and retrieve digital information electromagnetically. A hard drive consists of stacked disks with data recorded in concentric circles, read and written by heads on each side of the disks as they spin. Hard drive performance is measured by data rate and seek time. Common interfaces include ATA, SATA, and SCSI.
Hard drives are magnetic storage devices that store data permanently even when power is disconnected. They contain spinning platters coated with magnetic material and read/write heads that can detect and modify the magnetism of the platters to store and retrieve data. Hard drives connect to the motherboard via IDE or SATA interfaces and are installed in drive bays in the computer case. Proper installation requires setting jumpers, connecting power and data cables correctly, and securing the drive with screws.

It describes the heat sink, video memory, video BIOS, sizes of video cards, multi-card scaling capabilities, common device driver APIs like OpenGL and DirectX, market sizes and impact of integrated graphics, and ongoing performance improvements between AMD and NVIDIA graphics cards.
Graphics cards generate output images for display. They contain a GPU for 3D graphics processing and floating point calculations. RAMDAC converts digital signals to analog for CRT displays. Graphics cards connect via interfaces like AGP or PCI-Express slots. They use cooling devices to prevent overheating. Output connections include VGA, DVI, and HDMI ports to interface with displays and TVs. Installing a graphics card involves removing the old one, installing the new card, and installing updated drivers from the manufacturer's website.

Solid State Drive (SSD)
In 1995, M-Systems introduced the first flash-based solid-state drives. SSDs use non-volatile solid state memory like NAND flash or DRAM to store data without moving parts, distinguishing them from traditional hard disk drives. SSDs have significant performance advantages over HDDs with faster access times and read/write speeds, higher reliability since there are no moving parts, lower power consumption, and silent operation. However, SSDs currently have higher costs and offer less storage capacity than HDDs.

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.

THE SACRIFICE HOW PRO-PALESTINE PROTESTS STUDENTS ARE SACRIFICING TO CHANGE T...indexPub
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.
