A computer bus transfers data between components of a computer system. the bus as to when to place information on the bus, assert control signals, and so on. Data Bus can be thought of as a highway on which data travels within a computer. • Short for Extended Industry Standard Architecture, EISA was announced September of 1988. Thus buses can be categorize into: Internal buses: The processor uses several internal buses to interconnect registers and the ALU. x��Z�oܸ7��A��/�*\|I�RZ�)ׇ�W��녴>'��;3$%Q+ʲ[��p8�]v�{��O/��kV��s��{��6��9?�Y ��L��V��=�}��n��q��Li ��g�-=��S~U��G��C�e7Y��c�Qyx�e�w�e�u�p(8��M[�;��;�u ��Z3%��}ʳm��e��6̣ ��sV�h�F�R��2�ı�n��ó�ň��h��/�� :�\��`�6�Rl��낗��Os ��H��^Fb��'xkј�h}(*t��/=�}AEH�[��SU��o��(I�6��5��I)u�'�&A)-�5��/6�=�'��2�� C�0�B��8��]�7��)Ŕ��ֱb�ded@��I��*>��CŸ́�i��gܴ,�LKͬI>�c��ǲf20��E�y+0m�� kh��%Oފ�$� =��K�S$$)��X��a�.�LxɄ!&��q�)��x/gNm�R6�R��S��W��č%��2QsL ��rF��ʝ\��k˪ -e)r��A-܁��A �HD� }��I~�'��=�H|��yf��g�� >��lDj�)��*p��E��fO �m�� ]S�;B!p��Ε�}((U��>��%Q��[�W:�Q�r�(+�L,x1��tXi�>��xQX��"�F��½�)��8bA��Z8��0��*� ��M��a iNh�`�n��d��zl?�B4�1B� i��:�I�vw �%��6a�є��O��>q4��hU��m��5�6~��l��RF��oBЍ�^�nU��z,j��$�eo��U��=R��VΑ�ژ�C;��%��ƌ��F[�muHm�:��w�z�%JW�H�� ʱ٥\�$&Fj�� 7�c]��b�S|\NC��ғ-�a�4-`�d�P�D*�i1|m�ii�YUl�&�O��u�W�� -�w��ƻ.xHE�/GU�IK~��u�h�iO��:��n�s.��aB@��e=�r��N�Ts\� 9�x�^쵞X9ݲ�LǤ}z��߻+��c0��>8��e;HD�u�9b1o��t��z��z��}��=�Qk��Z��G�u��!��R`�ِ�2n��C��JG�+yKo7� 1�v�7d�5%�đC��$A �.

Data Bus A collection of wires through which data is transmitted from one part of a computer to another is called Data Bus. In computer architecture, a bus (a contraction of the Latin omnibus [citation needed], and historically also called data highway) is a communication system that transfers data between components inside a computer, or between computers.This expression covers all related hardware components (wire, optical fiber, etc.) Morris Mano 1 Lecture#04 Computer Register and System Buses A Register is a very fast computer memory, used to store data/instruction in-execution.t is a group of flip-flops with each flip-flop capable of storing one bit of information. The bus includes the lines needed to support interrupts and arbitration. 1 0 obj This pathway is used for communication purpose and it is established between … A data bus can transfer data to and from the memory of a computer, or into or out of the central processing unit (CPU). In the language of computers, the term buses actually refer to the system present within the hardware of the computer.This system is helpful in moving the data and without these buses; the computer can do calculations but lack the capability of moving the resulting information to any of the output device.
