How program instructions transfer in and out of memory?
The instructions have to remain in memory at all times while the program is running. They get there by loading the entire program into memory. The CPU's instruction registers keep track of the current instruction and the next instruction.
What is the purpose of version control?
It allows developers to update a program and keep track of the changes. It also allows them to rollback to a previous version if bad code was introduced.
Which type is generally faster and holds data and instructions while the data is being processed Which type of storage is generally slower but more permanent?
In a computer, there are many forms of media storage. We can catagorize them into 3 different categories - ROM (such as BIOS), RAM (memory), and Storage (flash drives, hard disk drives, etc.). Keep in mind that RAM retains information only when the power is on. ROM is usually stored in the BIOS chip. It basically gives your computer the most basic instructions to tell your computer to do a system check and boot your operating system. RAM is used by the computer to do just about everything. When your computer executes a program, for example, it loads the program into the RAM, interprets it, and runs it. It is generally faster than storage devices, but it cannot retain information once power is cut from it. Storage medium, as the name implies, for storing data. All data, programs, and files must be present on it for it to do anything useful.
What kind of data type is a structure?
A structure is not a data type. A structure is more of a collection if data types that can be referenced conveniently. Mainly we humans can keep on top of it, the computer does not care. struct foo { int a; long b; float c; char d[512]; int *e; };
How does the CPU differentiate between command and data?
In general the only difference between commands, or instructions, and data is the context in which each appears. If the CPU is fetching the contents of memory to get the next instruction, then it assumes that the Program Counter register points to commands. If the CPU is executing an instruction that needs to fetch data from memory, the data at the address specified by the instruction are fetched, assuming that the address points to data. This is what allows a program to be loaded into memory in the first place; the part of the operation system responsible for this operation treats the program as data, loading it into memory as instructed in the file. Then the OS branches to a specified place within that memory and begins fetching instructions there. This blurring between instructions and data has also been used in the past to allow a program to modify itself as it executes. This is usually considered poor practice; some operating systems, such as HP's OpenVMS, even set up memory page protections to keep this from happening.
What are the two uses of a computer at airports?
One is to keep data of all the tickets and who has bought them. The second is too keep track of luggage.
What type of software helps a computer control itself to operate efficiently and keep track of data?
operating system

What are some of the features of the Quickbooks Customer Manager program?

What software can help you separate and manage your computer?
There are a variety of programs that can be used to separate and manage a computer. It depends on what you are trying to do, but you can use a program such as Microsoft word in order to keep track of things and also Microsoft excel, if you have a windows computer.
If energy can never be created or destroyed what happens to the data that you delete from your computer?
Data are not energy.If they were, you could write a program to generate a continuous stream of random characters and output them through the printer port, and then use them to light your house. (Or to keep the computer running.)
What is responsible for setting and storing the computer's current time and data?
There is a dedicated chip called the RTC, short for real time clock. It has a small battery so that it can keep track of time when the computer is turned off.
What's a metered network?
A metered network is often regarded as a virtual meter which is used to measure your internet data on your computer device. People with a limited data plan are advised to use meter network to keep track of their data usage.
