The various components of the computer and the relationship between them is called the computer architecture. Almost all computers have the same structure.
Computer has three main parts, Input/Output unit, Central prpcessing unit and Memory unit.
Through Input Device, we input our data or instruction or program into the computer. Which is accepted by the CPU and stored in the appropriate place in the memory. When needed, ALU takes data and instruction from memory itself, where processing is done according to the order of the control unit and the results are sent to the output device or again kept in memory. All other units work under the control of the control unit.
In this post we have collected some important one line questions based on airthmetic and ligical unit, registers, microprocessor, memory unit, instruction format and cycle, read only memeory, motherboard, type of buses etc.
Must go through these computer architecture questions answers for your competitive exam prepration.
