30 mins and I will give Brianlest what is the difference between a method and a function in which ways are they similar why do y

omeli [17]

Answer:

For 1), you should also add that methods in C++ are called member functions. Thus, the difference between functions and methods in this context is analogous to the difference between functions and member functions in C++. Furthermore, languages like Java only have methods. In this case, functions would be analogous to static methods and methods would have the same meaning. For 2), you should add that a method is able to operate on the private instance (member) data declared as part of the class. Any code can access public instance data. A function is a mathematical construct. I would say all methods are functions but not all functions are methods

In comparing a multi-boot environment and an environment using a type II hypervisor which offers the best performance? Which wou

ElenaW [278]

Answer / Explanation

To answer this question, let us first understand what a multi boot environment is and what an environment using a hypervisor is:

Multiple-booting can be defined or simply refers to the process of installing different multiple operating system on a single computer and also to be able to determine which of the operating systems boot per time.

While:

Hypervisor or a type 2 hypervisor can be described as a form of virtual machine in form of a software that is installed on in an existing operating system of a computer. One of the main benefit of an hypervisor is it enables easy navigation of guest on your computer without actually navigating into your original or primary operating system plus it aid in fast system recovery.

If we now refer back to the question asked in respect to which i would offer as the most convenience, i would prefer the type 2 hypervisor as convenient because i am able to run an operating system inside another operating system so navigating between two operating system would be very easy as compared to the Multi-booting where i have to always shut down an operating system to navigate between the operating system because i can only use one operating system per time.

One day a subcontractor calls him saying that he needs a replacement check for the job he completed at 1437 Elm Street. Jonathan

zavuch27 [327]

Answer:

investigate where is checkbook or ledger in the accounting program, and this is a serious issue. The check needs to be done immediately, as the complete ledger is missing.

Explanation:

Ledger is the register in which all the transaction details are being given. The company whole account details is being mentioned in the ledger. We also know ledger as the checkbook. Undoubtedly, this s a serious issue as the complete ledger is missing. Hence, the process of investigation needs to be done immediately. However, he will first ask the other person who has the access to the accounting software. One should understand that all the details are in the ledger, and hence Jonathon needs to find the missing Ledger, and only then the error can be corrected.
