  BUSES: - The exclusion unit is the actual processing of data task placing inside this unit. It accept instructionsand data that have been fixed by the bus interface unit and then and exclusives the instruction personnel unit within the exclusion unit personnel unit with in the exclusion unit ALU. Registers and control logic and etc. ALU:  - The arithetic logic unit is the calculator part. It has hardware circuits like counter shift resisters etc.which perfors the arithetic and logical operations. BUS INTERFACE: -  The bus is a counication channel. Using with the icroprocessor. Interface with therest of the coputer devices. The Idea of bus is nothing but having a setup lines carrying soe signals to all thedevices in parallel. The bus control unit part runs bus operations for the icroprocessor transits the instructions!data other processor and other devices of the syste. It has the task of aking speed the syste. The bus is usedto fullest capacity in order to speeds up operations. ADDRESS BUS: -  The icroprocessor uses a setup lines for selecting a particular device or selecting a locationin eory. It is about to access the setup lines! which is used to specify what the #U about to access is called asan address bus. DATA BUS: -  After selecting a device using address bus icroprocessor has to either read inforation fro thedevice or writer inforation to the device the setup lines used for these purpose is called data bus stored carryinforation fro icroprocessor this bus is by directionally. CONTROL BUS: -  $et of lines is to control the flow of signals on the address bus and data bus. The control busspecifies the control signals that deterine. %ow and when the operation is to be perfored addresses bus andcontrol bus is unidirectional. BUSES IN EXPANSION SLOTS &xpansion slots one in different slots isone which different cards are can be fit in the otherboard. TYPES OF EXPANSION SLOTS: - '. 8 Bit Expansion Slots: - This was first type of bus to design for # (s. It has axiu clock speed).**+h,.  interrupts and ) +A channels. This bus is presently out dated. The slot color is block with out any cutting in between this card. /. ISA (INDUSTRY STANDARD ACITECTURE!: -  It is specified to provide  bit and '0 bit I12cards for data trance face and the card devices controlled it. I$A has to run '3 +%4 speed.It has '0 interrupts and eight +A channels. The slot color is black. 5. EISA (ENANCED ISA!: -  It was designed to provide 5/ bit data trance for but was not very popular. It is configured using software. It is backward copatible with '0-bit I$A standard.&I$A speed is  +%4. The color was black. ). ESA (OR! L-BUS: -  6ideo &lectronics standard Association designed this standard. It is 5/ bitstandard specifically designed for 6ideo cards. $ $I cards! I& cards. Its speed at the sae processor speed of icroprocessor. It slot color brown. 7. PCI (PERIPERAL CO#PONENT INTERFACE!: -  $pecification to provide 5/ bit and 0) bitdata transferred rates between interface then the device controller its runs at the sae clock speed of the icroprocessor. # I cards will autoatically configure theselves for IR8( s+A and I12 part addresses the slot color is white. 0. A$P (ACCELERATED $RAPICS PORT!: -  ata transferee in 0) bit and '/-bit speed is saeas processor. It is used for graphics! aniations and +aya software9s etc. *. PC CARDS:  - #ersonnel coputer eory card international association or pc card standard assistin popularity knows as the specification for interface cards. The specification for interface cards usedin obile coputers. They coe in '0 bit and 5/ bit versions the speed of clock 55 +%4.
