Detailed explanation-1: -Access time is the amount of time it takes for a computer to retrieve data from memory. It is measured in nanoseconds and is determined by the speed of the memory, its size, and how many components are involved in accessing it.
Detailed explanation-2: -Seek time is the time taken for a hard disk controller to locate a specific piece of stored data.
Detailed explanation-3: -(1) Memory access time is how long it takes for a character in RAM to be transferred to or from the CPU. Fast RAM chips have an access time of 10 nanoseconds (ns) or less. See SDRAM. (2) Disk access time is how long it takes to obtain the first data character after initiating a request.
Detailed explanation-4: -Access time is total time it takes a computer to request data, and then that request to be met. A good analogy is the time between you ordering a pizza and it being delivered. Access time pertains to devices such as memory, hard drive, CD-ROM or other mechanisms.
Detailed explanation-5: -Disk Access Time is defined as the total time required by the computer to process a read/write request and then retrieve the required data from the disk storage.
