Computing Systems

Which of the following is an example of the use of a device on the Internet of Things(IoT)

• A car alerts a driver that is about to hit an object.

• A hiker uses a GPS watch to keep track of her position.

• A refrigerator orders milk from an online delivery service.

• A runner uses a watch with optical sensors to monitor his heart rate.

What is the role of the compiler in the process of developing executable software?

• Managing specification files created as part of the development process.

• Running and testing the executable created by the programmer.

• Tracking older versions of the software.

• Translating a program written in an abstract, high-level language into a program with the same behavior expressed in machine code

Which of the following best describes a Web server?

• A computer system that delivers Web pages to clients.

• A computer system running software that provides a user-friendly interface for creating Web pages.

• A computer system that determines the shortest path between two computers over the internet.

• A computer system that translates domain names to IP addresses.

What is a benefit of local storage?

• You can access it anywhere.

• No need for a local tech team for maintenance.

• Not as vulnerable to hackers.

• Not as vulnerable to loss of data during a local disaster.

Which of the choices below would most likely cause a computer system to slow down normal execution time for local software applications?

• Not enough ROM memory

• Not enough RAM for memory intensive applications

• Not enough bandwidth

• Hard drive filled to capacity

The most significant concern about the Internet of Things is

• Too much training will be required to use it

• It is not compatible with other devices

• Data collected can be used and shared without user consent

• It will be too complex

Select the items that are embedded computer systems

• Washing Machine

• Car GPS

• Personal Computer

• Microwave Oven

Which definition defines machine code?

• This is considered to be the first “high level language”

• This is just a bunch of ones and zeroes representing the logic and data provided by the computer program

• this is the link between hardware and software in the abstraction chain

• C, C++, Java, FORTRAN, COBOL

Which definition defines Instruction Set Architecture?

• C, C++ and Java coming along later

• This is considered to be the first “high level language”,

• This is just a bunch of ones and zeroes representing the logic and data provided by the computer program

• this is the link between hardware and software in the abstraction chain

Which definition defines an application

• highest abstraction level, the one we as humans interact with

• used to code or implement logical processes called algorithms

• considered to be the first “high level language”,

• This is just a bunch of ones and zeroes representing the logic and data provided by the computer program,
