Q1: Answer the following as true or false Data are transferred to and from memory in groups of bits called words. Due to space and cost constraints, there is a unlimited number of registers in a CPU. Cache Memory It is basically fast memory device, Generally, the least recently used information is kept in the cache memory. The CPU can work with the information available in main memory only. Semiconductor memories are volatile in nature. It loses its content once we switch off the computer. DRAM is Slower and cheaper than SRAM. Basic Input Output System used to start up the operating system. It is stored on computer chip in a way that causes the data to remain even when power is turned off. PROM Programmable Read Only Memory; it can be programmed once as per user requirements. EPROM Programmable Read Only Memory; it can be programmed once as per user requirements.

These were the requirements: The software handle different jobs : • Print • Scan • Copy • Restart The printer can handle one job at a time, however, users still can send an order to execute jobs for the printer while it is running. The printer will handle the jobs sequentially based on job schedule details which are: 1. User can schedule a job to run now 2. User can set time to run job, like restart tomorrow at 12:00 3. Users can create a recurring Job which is set to automatically repeat based on the job schedule. Only authorized users should be able to submit a job. The user should be able to get a status or result for their job. The screen below shows the conceptual architecture. We created a job component that contains an interface called job and other operations that…
