SCIENCE – MATHEMATICS – ENVIRONMENTAL PERFORMANCE – 2021-22 IMPORTANT INFORMATION GANIT VIGYAN PARYAVARAN PRADARSHAN 2021-22

An important event is organized by the Government and the Department of Education to inculcate a scientific attitude in the students. In the past it was called as Science Fair, when Science is celebrated as Mathematics and Environment Exhibition.

An important letter and its topics have been announced this year.  On the basis that children can participate in it by preparing a model. In the past also called science fair. Nowadays it is called science-mathematics-environment-exhibiting and putting various works in it.  Participating in the preparation of various works with the help of science.

For this, the topics of this year’s science fair are announced.  Come through which you will be able to know and participate in this year’s topics. 

Many difficult tasks have become easier for human beings in everyday life due to many discoveries of science. Science needs help to make many tasks easier to live life.  For this, it is important for the teachers to keep an eye on the useful maths science demonstration for the children to participate and for the students to progress one step at a time.  Reach out to more students and try to get as many students as possible participating in science-math-environment-demonstration

Learn, Revise & Practice – Computer Awareness Com Interconnection of Units CPU sends data, instructionIs and information to the components inside the computer as well as to the peripheral devices attached to it. A bus is a set of wires used for interconnection, where each wire can carry one bit of data.

In other words, bus is a set of electronic signal pathways that allows information and signals to travel between components inside or outside of a 14 Ins It rep Microprocessor t the controbng element in o computer systom and nomotimes referted to an the chip. Microprocessor is the man hardware that drivea the computor It is a arge Printed Circult Board (PCB). 

which is used in al oloctronic systems such as computer, calculator digital systen, etc The speed of CPLI depends upon the type of mioroprocessor used. Intel 4004 was the first microprocessor made by 1971 by scientist Ted Hal and engineer Federico Faggin. Some of the popul microprocessors are Intel, Intel core 7, Dual cora, Pentium N, otc. place exec computer. A computer bus can be divided into two types 1. Internal Bus The internal bus connects components inside the motherboard like CPU and system memory. It is also called the system bus. Internal bus includes following buses (i) The command to access the memory or the I/O devices is carried by the control bus.

The data to be transferred is carried by the data bus. 2. External Bus It connects the different external devices; peripherals, expansion slots, I/O ports and drive connections to the rest of computer. It is also referred to as the expansion bus. Ina Another kind of memory is referred to as secondary memory of a computer system. This unit is used to permanently store data, programs and output. This unit does not deal directly with CPU. an ins Motherboard The main circuit board contained in any computer is called a motherboard. It is also known as the main board or logic board or system board or planar board.

All the other electronic devices and circnits of computer system are attached to this board like, CPU, ROM, RAM, expansion slots, PCI siots and USB ports.

The speed of processor is measured in millions f aycles per second or megahertz (MHz by clock Components on Motherboard Various components on motherboard are as follows (i) CMOS Battery (i) Fan (ii) BIOS Chip (iv) Expansion Slot speed DMA (Direct Memory Access) is a method that allows an input/output device to send or receive data directly to or from the main memory, by passing the CPU to speed up memory operations.
