![]() Burst Mode: In Burst Mode, buses are handed over to the CPU by the DMA if the whole data is completely transferred, not before that.There are 3 modes of data transfer in DMA that are described below. Control to define the mode of transfer such as read or write.It also sends word count which is the number of words in the memory block to be read or written.The starting address of the memory block where the data is available (to read) or where data are to be stored (to write).When BG (bus grant) input is 1, the CPU has relinquished the buses and DMA can communicate directly with the memory.Įxplanation: The CPU initializes the DMA by sending the given information through the data bus. When BG (bus grant) input is 0, the CPU can communicate with DMA registers. Through the use of the address bus and allowing the DMA and RS register to select inputs, the register within the DMA is chosen by the CPU. The unit communicates with the CPU through the data bus and control lines. The figure below shows the block diagram of the DMA controller. Therefore, the CPU can both read and write into the DMA registers under program control via the data bus. Note: All registers in the DMA appear to the CPU as I/O interface registers. Control register – It specifies the transfer mode.Word count register – It contains the number of words to be transferred. ![]() Address register – It contains the address to specify the desired location in memory.The DMA controller registers have three registers as follows. Interleaved DMA: Interleaved DMA are those DMA that read from one memory address and write from another memory address.

The whole syllabus is divided into 2 parts PART A: EMPLOYABILITY SKILLS In this part, you are supposed to read about employability skills. That means the students who were reading Foundation of Information Technology now it is said to be as Information Technology Code 402.CBSE Class 10 Information Technology will help students with learning basic communication skills and computing technology. The Information Technology subject in CBSE Class 10 is a revised version of the Foundation of Information Technology. There will be a new pattern for Information Technology Code 402 for class 10. CBSE Class 10 Information Technology Syllabus 2022-23 (new) This year CBSE has introduced a drastic change in the syllabus of Information Technology Code 402 for class 10. These changes might be useful for the students as this allows them to give the exam in a relaxed way. CBSE has introduced a new pattern of question papers too in which they have to give an exam of only 80 marks in the final term and the remaining 20 marks will be awarded by the school in internal assessments. There is a slight change in the course structure of almost all the subjects. There are many changes introduced in the syllabus of class 10 for the Board examination 2023. In this article, we have provided you a PDF of all the chapters of IT Code 402 for class 10 for the Board Examination This year CBSE has released the revised syllabus for class 10. ![]() Information Technology Code 402 Class 10 Notes PDF Download free Download the notes of Information technology code 402 class 10 according to the new syllabus.
