memory
Arithmetic-Logic unit (ALU) is the area of the microprocessor where various computing functions are performed on data. It is the part of CPU that carries out arithmetic and logic operations on the operands in computer instruction words. Operations performed by ALU include arithmetic operators, bit-shifting operators, and ______ operators.
logical
Input - transfer data and instructions in binary from the outside world to the microprocessor. Output - transfer data from the microprocessor to such output devices. ______ stores such binary information as instructions and data, and provides that information to the microprocessor whenever necessary.
Memory

ALU Signals: The ALU contains a variety of electrical input and output connections, which result in the digital signals being cast between the ALU and the external electronics. External circuits send signals to the ALU input, and the ALU sends signals to the external electronics. Opcode: The operation selection code specifies whether the ALU will conduct arithmetic or a logic operation when it performs the operation. Data: The ALU contains three parallel buses, each with two input and output operands. These three buses are in charge of the same amount of ______.

The Computer Interconnection System (CIS) provides the complete functional replication of the computer intra connection among CPUs, IOCs, and memories in separate computers. The CIS consists of two independent halves: The requestor extension interface (REI) – is a bus extender. It extends the bus up to 15 other computer cabinets providing an interconnected system of memory modules, CPUs, and IOCs. Direct memory interface (______) – is a responder or slave on the REI bus. Used to send requests from other enclosures (computers) to the module (CPU or IOC) requested. Bus is a communication pathway connecting two or more devices. It is a shared transmission medium. Register Array – consists of various registers. These registers are primarily used to store data temporarily during the execution of the program.
