What is the definition of a synchronous computer and how does it differ from an asynchronous computer?
A synchronous computer is a type of computer where all operations are coordinated by a clock signal. This means that all components of the computer work in a synchronized manner, following the same clock signal. On the other hand, an asynchronous computer does not rely on a central clock signal to coordinate operations. Instead, each component operates independently and communicates with each other using handshaking signals. This allows for more flexibility and potentially faster operation, but can also be more complex to design and implement.
What is the clock cycle time for the processor in this system?
The clock cycle time for the processor in this system is the duration it takes for one complete cycle of the clock signal, determining the speed at which the processor can execute instructions.
If a disk drive becomes active the disk controller provides this information to the CPU over the bus?
This is most likely the Control Bus the will send a signal to the CPU that the disk drive became active. If you noticed, eveytime you insert a CD, in Windows, a dialog pops up asking the user what to do. This occurs because the controller for this device sends that signal through the Control Bus which interupts the CPU.

How does a control unit operate in a computer?
Control Unit is the part of the CPU which controls the flow of data and co ordinates other device within it to perform a specific operation. It is said to be "brain within a brain". It receives external signals or commands which it converts into control signal to perform specific series of register transfer level operations. Since the ALU (Arithmetic Logic Unit) requires the availability of values (operands) in certain registers to perform a specific operations (say addition ), it is the work of CU to make available the operands and store the resulting answers in resultant register. A detailed information related to Control Unit Operations and types is available in the related link.
What are the uses of a NOT logic gate?
A NOT gate is used to invert the input signal, meaning it produces the opposite output to the input. It is commonly used in digital circuits for tasks such as signal inversion, logic gating, and arithmetic operations.

What is timing and control in computer architecture?
Timing pulses are used in sequencing the micro-operations in an instruction. For example, when LDA instruction is executed, the memory is read operation is performed in timing pulse T1 and memory writer operation is performed in timing pulse T2. Now the combination of the signal LDA and T1 can be used as a control signal for performing read operation. Similarly, the combination of the signal LDA and T2 can be used as a control signal for performing write operation.A master clock generator is used for controlling the timing for all register in a computer system. A state of a register cannot be changed by a clock pulse until it is enabled by the control signal, which are generated in the control unit and provide control inputs for multiplexers, processor register, and micro-operations. The control organization is of two types; hardwired control and micro-programmed control.Hardwired ControlIn a hardwired control, the control signals are generated by using the collection of combinational circuits. The main advantage of the hardwired control is that, it can be optimized to produce a fast mode of operation. Whenever a change or modification is to be done in the design, then the wiring among the various components needs to be done. Micro-Programmed ControlIn a micro-programmed control, a control memory is used for storing control information which is also programmed for initiating the sequence of micro-operations. Whenever any change or modification is required in the design, it can be done by updating the micro-program in the control memory.
What do you mean by control signal?
The control signal refer to the authorization that is to be given if a particular task is to be accomplished.
The most important factor determining which type of receptor a signal molecule will bind to is?
The most important factor determining which type of receptor a signal molecule will bind to is the specificity between the shape of the signal molecule and the complementary binding site on the receptor. Additionally, the affinity of the signal molecule for the receptor and the presence of any co-factors or co-receptors can also play a role in determining the binding specificity.
What is the function of the control unit in the CPU?
The control unit provides the timing and control signal to all operations of microcomputer. It control the flow of data between microprocessor and memory and peripherals.
What is the purrpose of a control unit in a processor?
Control unit generates all the control signals like memory read signal,i/o read signal,memory write signal etc
What is function of IO-M in 8085?
I/O and memory operations are differentiated by this status signal. When it is HIGH, I/O operation takes place and when LOW, memory operation takes place. This signal is combined with read/write in order yo generate I/O and memory control signals.
