AT power supplies have a 6-pin connector while ATX has a 20-pin connector. The power supply filters voltages, adjusts them to levels components need, and prevents damaging power from reaching outputs. It provides 3.3V, 5V, and 12V that digital circuits and cooling fans use. Newer ATX 2.0 standards introduced a 24-pin connector. Components like capacitors, coils, and switches regulate input current and suppress noise. Popular brands include Corsair, Cooler Master, and Thermaltake. Power supply prices range
Unit 4 software
Computer software provides instructions that tell computers what to do. There are two main types: system software and applications software. System software includes operating systems like Windows and MacOS, which control hardware and allow applications to run. Applications software are programs users interact with, like word processors, spreadsheets, databases, and presentation software. Operating systems manage all hardware, software, files and perform tasks without users' awareness. There are different types of operating systems based on how they allocate CPU time, such as batch processing, multiprogramming, multi-tasking, and time-sharing systems.
Components of a computer system
A computer system consists of hardware and software components that work together to take inputs, process them, and produce outputs. The hardware components include input devices to enter data, storage devices to store data and software long-term, and output devices to present the processed data to users. Examples of input devices are keyboards, mice, and microphones. Storage devices include hard drives, DVDs, CDs, and flash drives, which represent data using magnetic domains, lasers, or electric charge. Output devices such as monitors, printers, and speakers are used to display or present the output of the computer's processing to users.
Inside a computer
The system case contains and protects the main computer components. It has expansion bays for drives and ports on the front panel. The power supply converts AC to DC power for components.

Computer software is used to analyze data. There are three main types of software: system software that controls computer operations like the operating system; application software designed for specific tasks like word processing; and programming software that helps developers create other software. Hardware are the physical parts of a computer while software are the instructions that direct the hardware. Together, hardware and software work to accept input, process data, and produce output.

Day 2 hardware & software
Hardware and software are both essential components of a computer system. Hardware refers to the physical parts of a computer like processors, memory, storage devices, ports and peripherals. Software provides instructions to enable interaction with the computer and perform tasks through programming languages. There are two main types of software: systems software which controls and manages the hardware, and application software for specific tasks. Together, hardware and software work seamlessly through communication pathways like buses and ports to power the functions of a computer.
Block diagram of computer 02
A computer is a programmable machine that can execute a list of instructions. It has both hardware and software components. The hardware includes the central processing unit (CPU), memory, and input/output devices. The software provides instructions to tell the hardware what tasks to perform and includes both system and application programs. Data is stored in the computer in a format that can be manipulated by the hardware and software.

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.

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
9
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.
