The period of time that elapses between a request for information from disk or memory, and the information arriving at the requesting device. Memory access time refers to the time it takes to transfer a character from memory to or from the processor, while disk access time refers to the time it takes to place the read/write heads over the requested data. RAM may have an access time of 80 nanoseconds or less, while hard disk access time could be 18 milliseconds or less.
The amount of time for data requested from memory or disk to become available after the request was issued.
the time required for locating desired data on a disk.
Time interval between the instant that a piece of information is requested from a memory or peripheral device and the instant the information is supplied by the device. Access time includes the actual seek time, rotational latency, and command processing overhead time.
In the Windows file systems it is the time of day when the latter of the events of creating the file or last accessing the file for reading occurred. NTFS saves this file property.
The time required to position the laser read head over a specified sector and begin retrieving the data. For CD-ROM drives and CD-R devices, the access time generally ranges between 120 to 600 milliseconds, depending on the performance of the drive. Access time is also used in reference to other storage devices, such as hard disk drives and diskette drives.
The time it takes to retrieve a piece of information. With hard disks and compact discs, maximum access time is measured as the time it takes to move from one end of the disc to the other, find a piece of information, and transfer that information to RAM.
The time that it takes to access a device for read/write purposes. It is the sum of seek time + latency time + transfer time. Generally used as a metric for hard disk drives and memory.
The time it takes for a drive to access a data track and begin transferring data. In an optical jukebox, the time it takes to locate a specific disk, insert it in an optical drive, and begin transferring data to the host system.
Refers to the amount of time taken to begin aquiring data.
The time it takes a computer to retrieve stored data. Technically speaking, access time is the time interval between the instant a computer calls for data from a storage medium (such as a hard disk, CD-ROM, or the Internet) and the instant the data is delivered. If you leave your computer and your browser stays idle for too long, your ISP may automatically "cut your time off" and you will need to dial-up to regain access.
The access time is the amount of time that it takes the computer gets data off of a local or network disk.
The time interval between the instant at which information is: (a) called for from storage and the instant at which delivery is completed, (b) ready for storage and the instant at which storage is completed.
(computer science) the interval between the time data is requested by the system and the time the data is provided by the drive; "access time is the sum of seek time and rotational latency and command processing overhead"
The amount of time, including seek time, latency and controller time, needed for a storage device to retrieve information.
The amount of time it takes for a storage peripheral to transfer data to the CPU, measured from the instant the request is made until the instant the data is received.
The interval between the time a request for data is made by the system and the time the data is available from the drive.
The time required to retrieve data from a storage device and transmit it to a specified location.
The performance of fixed or removable drives is measured by seek time or the amount of time required for the arm of a direct access storage device to position itself over the track where the required information is stored on the disc.
The time required by a Harddisk or CD-ROM drive to seek the requested track and transfer the data to the destination (PC or SSHDR1). Since the access time depends on the current position of the disk-head and the position of the requested data, this time can vary significantly. Therefore, specifications usually refer to the average access time.
The total time required to find, retrieve, and display information. Access time varies from minutes on a videotape, seconds on videodisc and CD-ROM, to milli-seconds on a computer.
The time needed for the reader to cross the CD gathering information (between 120 and 600 milliseconds, depending on the reader).
Amount of time it takes for a hard drive to find and retrieve a piece of information. Also known as seek time.
The maximum time interval between stimulus and response required to execute a particular function such as a memory cell call. Access time may correspond to a device as a whole or to a subfunction of a device.
Time interval between the instant at which a control unit initiates a call for data and the instant at which delivery of the data is completed. Access time equals latency plus transfer time.
the time interval at which computer data is requested from a storage device and the moment that delivery process starts.
the time a computer requires to locate data in its external storage
Total time a storage device requires to find and retrieve a piece of information. more...
In automatic data processing: 1. The time interval between the in- stant at which data are called for from a storage device and the instant delivery is completed; i.e., the read time. 2. The time interval between the instant at which data are requested to be stored and the instant at which storage is completed; i.e., the write time.... read full article
"Seek Time" + "Rotational Latency" = "Access Time" the time it takes to exactly locate data on a drive.
How long it takes for a hard drive to find a piece of data.
The time it takes to get data into and out of a memory device.
The time required to retrieve information from the computer's memory or from a disk drive, server, or network.
n. 1. The amount of time it takes for data to be delivered from memory to the processor after the address for the data has been selected. 2. The time needed for a read/write head in a disk drive to locate a track on a disk. Access time is usually measured in milliseconds and is used as a performance measure for hard disks and CD-ROM drives. See also read/write head, seek time, settling time, wait state. Compare cycle time.
The ammount of time something takes to find a piece of information and allow it to be used by other devices.
The total time required to find, retrieve and commence using information, also known as Lead Time.
The amount of time it takes a computer to locate an area of memory for data storage or retrieval.
The length of time required for a computer system to process a data request and retrieve the data from memory, a storage device, or the Internet. This time may range from a few nanoseconds when accessing a file in the computer's memory to hours when retrieving data from the Internet.
Time interval between the instant that a piece of information is sent to the memory device and the instant it returns.
The time it takes for a disk drives head to reach a sector after the issuance of a read or write command. Command overhead + seek time + latency = access time.
the total time required to deliver data from the CD-ROM.
The period of time during which an access point is unlocked. (Also see shunt time).
The average time it takes a device (usually a disk drive) to find a random piece of data on a disk. Access time is measured in milliseconds (the lower the number, the faster the drive). Good access times for a hard drive are between 10 ms and 15 ms. See also transfer rate.
The interval between a request for stored information and the delivery of the information; often used as a reference to the speed of memory.
refers to the time required for a data storage device to locate and retrieve data.
The length of time required to store or retrieve data, or to access a word in main memory. In other words, the time passing, say, between giving a 'read' signal and the data being available at the output.
The average time (in nanoseconds) for RAM to complete one access. Access Time is composed of address setup time and latency (the time it takes to initiate a Request for data and prepare access).
The amount of time that an access door is unlocked for entry.
The time required by the read/write head to reach the right position on the disk, i.e. the time required for access to specific data. Access time equals latency plus positioning time.
The average time interval between a storage peripheral (usually a disk drive or semiconductor memory) receiving a request to read or write a certain location and returning the value read or completing the write.
The time interval between the instant a computer makes a request for a transfer of data from a secondary storage device and the instant this operation is completed.
