Describe the two hardware methods for establishing priority in a few words.

A processor uses a serial link to communicate with a keyboard for word processing. A typist using this keyboard can type at rates peaking at 120 words per minute, where a word is 6 characters (including spaces and punctuation). The characters will be transmitted from the keyboard in 8-bit ASCII with one stop bit and no parity. Only consider these and no special characters. The programmer writes setup and polling service routines based on a minimum baud rate, but then finds that the keyboard will only interface at 19.2 Kbaud. Will the polling service routine have to change? Why or why not? Baud Rates 300 600 1200 2400 4800 9600 19200

There are a few different configurations that might be used for the central processing unit (CPU) of a computer. The general register, a single accumulator, or a stack are the three possibilities. There are positives and negatives associated with each option individually. It is up to you to provide a response, and the response that you provide might be accurate or it could be erroneous.

Consider a system in which Data and Code are distinct. When necessary, the CPU acquires instructions or data using two base-limit register pairs. Data and instructions should be kept separate. By default, this pair is read-only, allowing several users to share the programme. This method should be compared to others.
