 GroveStudies Production: Cache memory Cache memory, also called cache, supplementary memory system that temporarily stores frequently used instructions and data for quicker processing by the central processing unit (CPU) of a computer. Levels of memory: Level 1 or Register – It is a type of memory in which data is stored and accepted that are immediately stored in CPU. Most commonly used register is accumulator, Program counter, address register etc. Level 2 or Cache memory – It is the fastest memory which has faster access time where data is temporarily stored for faster access. Level 3 or Main Memory – It is memory on which computer works currently. It is small in size and once power is off data no longer stays in this memory. Level 4 or Secondary Memory – It is external memory which is not as fast as main memory but data stays permanently in this memory. The performance of cache memory is frequently measured in terms of a quantity called Hit ratio. Hit ratio = hit / (hit + miss) =

 GroveStudies Production: Computer Memory The computer memory holds the data and instructions needed to process raw data and produce output. The computer memory is divided into large number of small parts known as cells. Each cell has a unique address which varies from 0 to memory size minus one. Computer memory is of two types: Volatile (RAM) and Non-volatile (ROM). The secondary memory (hard disk) is referred as storage not memory. But, if we categorize memory on behalf of space or location, it is of four types: Register memory Cache memory Primary memory Secondary memory Register Memory Register memory is the smallest and fastest memory in a computer.A register temporarily holds frequently used data, instructions, and memory address that are to be used by CPU. They hold instructions that are currently processed by the CPU. All data is required to pass through registers before it can be processed. So, they are used by CPU to process the data entered by the users. Registers hold a sma

GroveStudies Production: Hardware  computer hardware is the physical components that a computer system requires to function. It encompasses everything with a circuit board that operates within a PC or laptop; including the motherboard, graphics card, CPU (Central Processing Unit), ventilation fans, webcam, power supply. Software Software, which is abbreviated as SW or S/W, is a set of programs that enables the hardware to perform a specific task. All the programs that run the computer are software. The software can be of three types: system software, application software, and programming software. 1) System Software The system software is the main software that runs the computer. When you turn on the computer, it activates the hardware and controls and coordinates their functioning. The application programs are also controlled by system software. An operating system is an example of system software. i) Operating System: An operating system is the system software that works as an interf

Grovestudies Production :-  1. V.V. Dakuchaev and associates investigated unique horizontal layer in the soil that were associated with different combination of climate, vegetation and underlying soil materials. 2.  Pedology refers to the study of the origin of soil in their natural environment. 3. The pH is negative logarithm of the concentration (activity) of h+ ions in the soil solution. 4. Clay and humus have a large surface area per unit weight due to their extremely small particle size. 5. Vegetative cover reduces the natural soil erosion rate there by slowly down the rate of mineral soil removal. 6. Soil genesis is caused by weathering and breaking down of organic matter translocation (one place to another) and accumulation. 7. A vertical exposure of origin sequence is known as soil profile. 8.  Alfisol soils are mostly high in respect of their fertility and are used either fertility and are used either as crop land or forest or rengeland. 9. The soil texture is not changed by

GroveStudies Production: Flame of the Forest !!  Scientific name:- Butea monosperma Family : Fabaceae Order : Fabales Kingdom : Plantae Flame of the Forest ! पलाश एक वृक्ष है जिसके फूल बहुत ही आकर्षक होते हैं। इसके आकर्षक फूलों के कारण इसे "जंगल की आग" भी कहा जाता है। पलाश का फूल उत्तर प्रदेश का राज्य पुष्प है और इसको 'भारतीय डाकतार विभाग' द्वारा डाक टिकट पर प्रकाशित कर सम्मानित किया जा चुका है।प्राचीन काल से ही होली के रंग इसके फूलो से तैयार किये जाते रहे है। It is used for timber, resin, fodder, medicine, and dye.

Organic Farming :-   “Organic agriculture can be defined as: an integrated farming system that strives for sustainability, the enhancement of soil fertility and biological diversity whilst, with rare exceptions, prohibiting synthetic pesticides, antibiotics, synthetic fertilizers, genetically modified organisms, and growth hormones”.  Organic farming is an alternative agricultural system which originated early in the 20th century in reaction to rapidly changing farming practices.  It relies on fertilizers of organic origin such as compost, manure, green manure, and bone meal and places emphasis on techniques such as crop rotation and companion planting. Farming system: Farming system is a resource management strategy to achieve economic and sustained agricultural production to meet diverse requirements of farm livelihood while preserving resource base and maintaining a high level of environment quality.  Conservation Agriculture:   Conservation Agriculture it is a way of farming that
