When a motherboard fails, you can select and buy a new board to replace it. Suppose the motherboard in your computer has failed and you want to buy a replacement and keep your repair costs to a minimum. Try to find a replacement motherboard on the internet that can use the same case, power supply, processor, memory, and expansion cards as your current system. Share your research with the class and discuss the following in a minimum of 175 words: If you cannot find a good match, what other components might have to be replaced (for example, the processor or memory)? What is the total cost of the replacement parts?

omg taking this same test i was stuck on the same question i was too lazy to read the book sadly i cant really give you an answer to this question too complex the answer will be in chapter 5 of the cay

answer: internal fragmentation is the difference between the (fixed) size of a memory hole and the data within in that memory. for example, if a 1,024 byte block of memory holds 800 bytes of data, then the 224 bytes difference is considered lost to internal fragmentation.

external fragmentation occurs when the sum of memory fragments is large enough to satisfy a request, but the holes are non-contiguous and the request cannot be satisfied. this can occur when memory is dynamically allocated and freed.

explanation:

that without the operating systems you would have to control and synchronize computer hardware.
