Answer:
- Scrape or remove food bits from the surface.
- Wash the surface.
- Rinse the surface.
-
Sanitize the surface.
- Allow the surface to air-dry.
Explanation: These are steps for cleaning and sanitizing.
I would have to say the answer is D.) A communication plan. Hope this helps! :-)
Answer:
Interrupt (INT) helps operating system to stop work on one process and start work on other process using interrupt signals.
Explanation:
Purpose of interrupts:
• Interrupts are useful when an I/O device needs to be serviced only occasionally at low data transfer rate.
• For example, when a peripheral requires the attention of the processor to perform an I/ O operation.
A trap:
• also known as an exception or a fault, is typically a type of synchronous interrupt caused by an exceptional condition
• is a software-generated interrupt.
• For example it's caused by division by zero or invalid memory access.
Can traps be generated intentionally by a user program? Yes.
If so, for what purpose?
• the usual way to invoke a kernel routine (a system call) because those run with a higher priority than user code.
• Handling is synchronous, so the user code is suspended and continues afterwards.
• In a sense they are active - most of the time, the code expects the trap.
Keira is using the software development life cycle to create a new app. She has the pseudocode for her program. The next stage for Keira is CODING.
Explanation :
- SDLC or the Software Development Life Cycle is a process that produces software with the highest quality and lowest cost in the shortest time. SDLC includes a detailed plan for how to develop, alter, maintain, and replace a software system.
- SDLC involves several distinct stages, including planning, design, building, testing, and deployment. Popular SDLC models include the waterfall model, spiral model, and Agile model.
- The steps of the SDLC are given below :
- Identify the current problems. “What don’t we want?”
- Plan. “What do we want?”
- Design. “How will we get what we want?”
- Build. “Let’s create what we want.” This SDLC stage develops the software by generating all the actual code. If the previous steps have been followed with attention to detail, this is actually the least complicated step.
- Build is the phase which Keira should move onto in the SDLC
- SDLC done right can allow the highest level of management control and documentation. Developers understand what they should build and why. All parties agree on the goal up front and see a clear plan for arriving at that goal. Everyone understands the costs and resources required.
This question has 2 answers that I can see.
The first one would be a Dial Up Modem. These devices allow (or allowed, since they're pretty much obsolete) a computer to communicate over the phone lines and access the internet.
The second option for an answer would be a DSL Modem/Router. In a sense, a DSL (Standing for Digital Service Line) is a bit of a predecessor to traditional Dial Up, using a digital telephone line (However not the frequencies used for voice) to connect a computer or set of computers together and to the internet.
