The document discusses the basic parts of a computer. It describes the four main parts as the CPU, display, input sources, and memory. The CPU performs all calculations and is housed in the tower. Inside the tower are the CPU fan, RAM, and ROM (hard drive). The RAM is the computer's short-term memory and impacts performance. The ROM is long-term storage for files, applications, and more. Both RAM and ROM come in varying storage sizes measured in megabytes and gigabytes.

Computer Fundamentals
The document provides an overview of the key components of a computer system, including the input and output units, memory, central processing unit, and various ports. It describes the functions of these components and how they work together to process data and perform tasks.
Computer basics
Computer consists of many parts that work together, including the central processing unit (CPU) that acts as the computer's brain. Information is input using devices like keyboards and mice, processed by the CPU using memory components, and output through devices like monitors and printers. The motherboard forms the core of the computer, connecting the CPU and memory chips. Storage devices like hard drives and flash drives hold programs and files on magnetic disks, while other components like video and sound cards manage outputs.
Introduction to Computer Hardware slides ppt
The document provides information about computer hardware components including the system unit, motherboard, processor, memory, and storage devices. It discusses the system unit as containing the main electronic components including the motherboard, processor, memory, and disk systems. The motherboard is described as the main circuit board where hardware components connect and contains the BIOS. Types of memory including RAM and ROM are outlined. Finally, magnetic and optical storage devices such as hard disks, CDs, and DVDs are introduced.

The CPU processes data and instructions and its speed is determined by bit size. The CPU fits into the motherboard beneath the heatsink. RAM temporarily stores files for fast access but is volatile, while ROM permanently stores startup instructions. Expansion cards like audio, video, and network cards add functionality. Storage devices include floppy disks, optical drives, hard drives, and external drives connected via interfaces like USB, SATA, and SCSI. Input devices control the computer and output devices display or output information.

This presentation was provided by Steph Pollock of The American Psychological Association’s Journals Program, and Damita Snow, of The American Society of Civil Engineers (ASCE), for the initial session of NISO's 2024 Training Series "DEIA in the Scholarly Landscape." Session One: 'Setting Expectations: a DEIA Primer,' was held June 6, 2024.LAND USE LAND COVER AND NDVI OF MIRZAPUR DISTRICT, UP
This Dissertation explores the particular circumstances of Mirzapur, a region located in the
core of India. Mirzapur, with its varied terrains and abundant biodiversity, offers an optimal
environment for investigating the changes in vegetation cover dynamics. Our study utilizes
advanced technologies such as GIS (Geographic Information Systems) and Remote sensing to
analyze the transformations that have taken place over the course of a decade.
The complex relationship between human activities and the environment has been the focus
of extensive research and worry. As the global community grapples with swift urbanization,
population expansion, and economic progress, the effects on natural ecosystems are becoming
more evident. A crucial element of this impact is the alteration of vegetation cover, which plays a
significant role in maintaining the ecological equilibrium of our planet.Land serves as the foundation for all human activities and provides the necessary materials for
these activities. As the most crucial natural resource, its utilization by humans results in different
'Land uses,' which are determined by both human activities and the physical characteristics of the
land.
The utilization of land is impacted by human needs and environmental factors. In countries
like India, rapid population growth and the emphasis on extensive resource exploitation can lead
to significant land degradation, adversely affecting the region's land cover.
Therefore, human intervention has significantly influenced land use patterns over many
centuries, evolving its structure over time and space. In the present era, these changes have
accelerated due to factors such as agriculture and urbanization. Information regarding land use and
cover is essential for various planning and management tasks related to the Earth's surface,
providing crucial environmental data for scientific, resource management, policy purposes, and
diverse human activities.
Accurate understanding of land use and cover is imperative for the development planning
of any area. Consequently, a wide range of professionals, including earth system scientists, land
and water managers, and urban planners, are interested in obtaining data on land use and cover
changes, conversion trends, and other related patterns. The spatial dimensions of land use and
cover support policymakers and scientists in making well-informed decisions, as alterations in
these patterns indicate shifts in economic and social conditions. Monitoring such changes with the
help of Advanced technologies like Remote Sensing and Geographic Information Systems is
crucial for coordinated efforts across different administrative levels. Advanced technologies like
Remote Sensing and Geographic Information Systems

Changes in vegetation cover refer to variations in the distribution, composition, and overall
structure of plant communities across different temporal and spatial scales. These changes can
occur natural.

Wound healing PPT
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.
How to Make a Field Mandatory in Odoo 17
In Odoo, making a field required can be done through both Python code and XML views. When you set the required attribute to True in Python code, it makes the field required across all views where it's used. Conversely, when you set the required attribute in XML views, it makes the field required only in the context of that particular view.

Computers module 1
- 1. Computers - Module 1
- 2. The Basic Computer A computer is simply a device that accepts inputs, performs functions, and produces an output. Many people are familiar with a computer, but they are unaware of the parts that make up the computer and what they do.
- 3. The Basics The computer is made of 4 basic parts CPU Display (output sources) Input sources Memory
- 4. CPU The CPU or Central Processing unit is the brain of the computer. This is where all the calculations are performed. It is a silicon chip and housed in the tower. Tower
- 5. Inside the Tower Removing the cover reveals the inside of the computer. The large fan in the middle covers the CPU chip keeping it cool. Fan covering CPU
- 6. Inside the Tower There are 2 other main points in the tower. To the right of the fan there are 2 strips. These are the RAM of the Computer. RAM stands for Random Access Memory. This is the memory the computer uses and erases many times. The more RAM a computer has the less stress will be placed on the CPU. RAM
- 7. Close up of the RAM RAM comes in sticks. It is in Megabytes or Gigabytes Ideally, you want as much RAM as your computer will hold. Other than the CPU, RAM has the most impact of the performance of a computer.
- 8. Inside the Tower The large rectangular box in the bottom right is the ssecond type of memory in a computer, the ROM. ROM stands for Read Only Memory. This is where the long term memory is. Photos, games, applications, music, and other files are stored here to be retrieved at a later date. ROM is also called the Hard Disk ROM or Hard Disk
- 9. Close up of the Hard Drive or ROM The Hard Drive is rated in terms of bytes. Gigabytes are 1000 Megabits Terabytes are 1000 Gigabytes The more memory you have the more information you can store on the computer.
