What else can I help you with?
What is the term that defines excessive swapping of files between RAM and virtual memory?
multitasking this answer is wrong. right answer is thrashing.
How do you connect to computers that are across town?
The safest and easiest way to connect computers across time is with a VPN. A VPN is a virtual private network that makes a tunnel between two or more computers.
What term is used to describe two computers acting as if there is a dedicated circuit between them even though there is not?
Virtual Circuit
What is thrashing and how it will be overcome?
when there are too many processes available and memory is low, than processor remains busy in swapping in and out the pages from disk in order to overcome it: 1) increase memory 2) reduce multi programming level
Virtual Memory refers to your computer's swapping of data currently in use between what types of memory?
We load our computers with so much runtime JUNK that RAM (Random Access Memory) can quickly be used up. All of the little applications that we think are cute, special or "OMG, I just CAN'T live without it", take up memory... but most of those little applications aren't really active at any specific point in time. So: the operating system determines what processes aren't currently active, "swaps" them out to a special section of disk that has become known as "virtual memory", allowing that memory space to be freed for something that actually needs to run... NOW. Virtual means, "sort of but not really", so virtual memory acts like memory... sort of, but it's not really memory. Disk swapping (that's what happens when the computer gets busy moving memory out to disk and moving "VIRTUAL MEMORY" back into memory) takes quite a bit of computer overhead and is responsible for slow running computers. Many people think their computers are old and worn out because they are running slow, but in reality, they've just accumulated a lot of junk that's running in background, and that junk holds onto memory, forcing more disk swapping (caching) that results in slower running computers. There are two solutions to the problem: 1. Get more RAM (Random Access Memory) that fits and will run in your computer. 2. Get rid of some of the junk and useless programs that are loaded on your computer. I once worked on a lady's computer that had 36 copies of some spyware and each copy was reporting back to "the mother-ship". All that memory overhead and network communication brought the computer to a halt. It took her over 5 minutes to load a page. After I cleared that junk off her computer, everything ran like new.
How do you swap bodies with a dog?
Swapping bodies with a dog is not scientifically possible. The concept of body swapping, also known as "identity transfer," is currently limited to science fiction and fantasy. In reality, the biological and physiological differences between humans and dogs make such a phenomenon impossible.
What is the different between swapping and paging?
Nothing -- they are the same thing.
What is difference between paging and swapping?
Nothing -- they are the same thing.
Is Creation of virtual memory carried out by the ALU?
No. The ALU is for Arithmetic and Logic. Virtual memory requires several interesting pieces of hardware. The main one is an address translation unit. When the CPU sends the address of a byte that it wants to retrieve from RAM, the address translator changes the address from where the CPU 'thinks' the byte is, to the address of where it actually is. The CPU also has to be able to execute 'exceptions' which are like interrupts. These happen when the CPU tries to access a page that is not currently in RAM. There must be a storage device to hold all of the pages that are currently not in RAM. Usually this is a disk. There has to be virtual memory software currently in RAM so that it can be executed as needed. It is responsible for handling exceptions, swapping pages between RAM and disk, and keeping the data in the address translator updated. There are different architectures, and further details, but I think those are the basics.
What is thrashing in c?
Thrashing in C refers to excessive swapping of data between RAM and virtual memory, significantly slowing down the system due to the high overhead involved in managing memory. It typically occurs when a program doesn't have enough physical memory and constantly swaps data in and out of virtual memory.
True or false Covalent bonds can best be describe as a swapping of electrons?
False. Covalent bonds involve the sharing of electrons between atoms, not the swapping of electrons.
What enables a computer to perform number of operations simultaneously?
Truthfully - they don't ! Computers can only do one thing at once. It's just that they work so quickly swapping between each task that is just seems they're doing multiple things at once.
