random access
method by which sources of information within a computer can be located randomly
an entity can be directly referenced independently of any other entity A file that is directly accessed can have records written in the middle without records on either side written Records (entities) are accessed by an address
An access method in which records can be read from, written to, or removed from a file in any order
The ability to access data instantly The MD4 quick locate functions allow you to locate any point instantly Tape-based recorders do not have random access capabilities because they have to wind a tape, which takes time
Access mode in which records are obtained from or placed into a mass storage file in a nonsequential manner so that any record can be rapidly accessed
An access mode where records are placed in non-sequential order in mass storage so they can be accessed rapidly This is the same as "DirectAccess"
A database retrieval method in which the system can go directly to the record without having to read the preceding records; also called direct access 9 6
Describes the ability of a storage device to go directly to the required memory address without having to read from the beginning every time data is requested There is nothing random or haphazard about random access; a more precise term is direct access In a random-access device, the information can be read directly by accessing the appropriate memory address Some storage devices, such as tapes, must start at the beginning to find a specific storage location, and if the information is towards the end of the tape, access can take a long time This access method is known as "sequential access "
Unscheduled access to communications medium in which stations transmit when ready (possibly after sensing medium), and later resolve any conflicts that arise
Retrieving data based on knowledge of the address of the data The term random access means that all storage locations in the memory are equally accessible and they do not require any sequential access It is a synonym and alternative for direct address
A system can access data within particular time, regardless of the location of the data This is one of the characteristics of disk type of recording media As far as MO disk is concerned, the access time is around second
Storage method that allows information retrieval without regard to the order in which it was recorded
A technique of accessing (reading) a word of data from a memory structure by the CPU Since a word in the memory can be accessed directly, the time required is independent of its location (address) in the memory structure It is sometimes called a "direct access" method
Reading locations directly without having to read in a particular sequence
An access mode in which the program-specified value of a key data item identifies the logical record that is obtained from, deleted from or placed into a relative or indexed file
With reference to data storage device, random access refers to being able to access specific data quickly by going directly to its location on the medium Diskettes, harddisks, and CD-ROM drive all allow random access
Memory The primary memory in a computer Memory that can be overwritten with new information The "random access" part of its name comes from the fact that all information in RAM can be located - no matter where it is -in an equal amount of time This means that access to and from RAM memory is extraordinarily fast By contrast, other storage media-like magnetic tape-require searching for the information, and therefore take longer
As opposed to linear access, where data or items must be accessed sequentially (like on a cassette tape), random access allows you to randomly jump to any item on a piece of media, and retrieve or operate on it immediately (like a CD, or hard drive) The biggest difference is in the speed with which items can be accessed By allowing you to "skip" to the item you want, random access greatly increases speed and productivity
This means that an algorithm can access any element xi of a sequence immediately (by just specifying i) It doesn't have to go through x1, ,xi-1 first Note that this has nothing directly to do with randomness
The ability to locate a record in a file through relative seeks (see also sequential access and keyed access) Once the desired record is located, you can use sequential access to read subsequent records
