Introduction to computer system.pptx
A computer is an electronic device that processes data according to instructions stored in its memory. It accepts raw data as input, processes the data, stores the results if needed, and provides output. Computers can solve problems quickly and accurately, store and retrieve large amounts of data, and display information through documents and images. The basic components of a computer system are hardware and software. Hardware refers to the physical parts like the processor and memory, while software provides instructions for the hardware to function. Together, hardware and software allow computers to perform a wide range of tasks.
Business intelligence - benefits of using an online analytical solution
This document discusses the benefits of using a business intelligence (BI) solution compared to Excel-based reporting. BI solutions can analyze data faster, more efficiently, and accurately from multiple sources. They generate more detailed, wider-ranging, and accurate reports. BI also saves costs through greater efficiency, elimination of inaccurate data, and improved ability to predict trends. While Excel is flexible, BI mitigates issues like lengthy manual operations, reliance on qualified staff, and lack of historical data for comparison. The document provides an example of how a BI solution could improve an organization's item valuation, costs, and yield analysis reporting.

history of computers.pptx
The history of computers began around 2000 years ago with the invention of the abacus in ancient Babylonia. In 1642, Blaise Pascal created one of the first digital computers. Herman Hollerith developed punched cards in the 1890s that could automatically read and store information without human assistance, laying the foundation for modern data processing. In 1942, the ENIAC was created at the University of Pennsylvania, occupying 1800 square feet and using 18,000 vacuum tubes. It was about 1000 times faster than previous computers. Through the 1950s-1980s, technologies like magnetic core memory, transistors, semiconductors, microprocessors advanced computing power and allowed for personal computers.
Nature of Mathematics..pptx
Mathematics reveals hidden patterns that help us understand the world. It provides training for logical thinking and problem solving. Mathematics is the study of patterns, orders, numbers, geometric objects, algorithms, and change. It has its own precise language and symbols to concisely represent concepts, like pi (π). Mathematics allows abstract concepts to be expressed concretely and helps solve problems in daily life. It is an intellectual exercise with its own rules and puzzles. Mathematics yields results that are either exactly right or wrong, with no in-between.
Input devices.pptx
Input devices allow users to enter data and instructions into a computer. Common input devices include keyboards, mice, scanners, microphones, and light pens. Keyboards are the most common input device and are used to type data and instructions into memory. Mice are pointing devices that control cursor movement on screen when rolled over a mousepad. Scanners convert printed text and images into digital format. Microphones convert spoken words into electric signals for voice recognition. Light pens are used to draw directly on the computer screen.
Output devices and types of printers.pptx
Monitors and printers are two common output devices that receive data from computers. Monitors display information visually while printers provide a hard copy output. There are different types of monitors including CRT and LCD, and different types of printers such as inkjet printers, laser printers, and dot matrix printers. Each printer type uses a distinct printing method such as spraying ink, using a laser beam, or striking pins to produce characters on paper.
Qualities and professional comepetencies of computer science teacher.pdf

Role of administration in inclusive school.pptx
The school administration plays a key leadership role in ensuring the successful implementation of inclusive education. Some of the main responsibilities of the administration include: (1) Ensuring accessibility by providing infrastructure like ramps and accessible classrooms, toilets, etc. (2) Working to build positive attitudes towards disability among students and teachers. (3) Organizing appropriate human resources like qualified teachers and special educators. (4) Arranging appropriate teaching materials and resources. (5) Supervising and supporting teachers. (6) Monitoring student evaluation and providing remedial instruction.
Co curricular activity.pptx
Co-curricular activities are organized in addition to academic work and are now considered an important part of the school curriculum. They contribute to the all-round development of students by developing qualities like leadership, cooperation and discipline. There are many types of co-curricular activities including physical activities like sports, academic activities like science clubs, literary activities like debate, cultural activities like music and dance, social activities like NSS and moral activities like celebrating important days. Co-curricular activities help bridge the gap between theory and practice and motivate students while teaching them how to learn by doing.
SWOC analysis.docx
A SWOC analysis is a strategic planning tool that can be used during curriculum assessment to identify strengths, weaknesses, opportunities, and challenges (SWOC). It provides a framework for collaborative discussion to assess existing degree programs. The objective is to develop areas of focus for improving the curriculum. A SWOC analysis considers internal factors like strengths and weaknesses that are somewhat controllable, and external factors like opportunities and challenges that are less controllable. It can be used for self-assessment, educational, or career planning.
Unit analsysis.pptx

Computer Network.pptx
A computer network consists of servers that store and share data, clients that can access data from other computers, and transmission media like wires or cables that connect all the devices. Special network interface cards are used to format and transmit data between computers on the network. A hub broadcasts all incoming data requests to the entire network while a switch uses addressing to send requests directly to the intended server. Routers connect multiple computer networks together, allowing communication between different local area networks.
Computer Memory.pptx
Computer memory comes in three main types: cache memory, primary/main memory, and secondary memory. Cache memory is the fastest type and acts as a buffer between the CPU and main memory to store frequently used data and instructions. Main memory is volatile and holds the data and instructions currently being processed, while secondary memory is non-volatile storage like hard disks used to permanently store data. The different memory types vary in speed, capacity, volatility, and purpose in a computer system.
