Any data that fits within the word-length of the CPU will be accessed in a single cycle and therefore has the fastest access. This is why programmers do not pass arguments larger than a pointer to functions. Arguments are always passed by value, which means they must be copied, but copying a pointer has no overhead.

What is seak time?
"Seek time" refers to the amount of time it takes for a storage device, such as a hard drive, to locate and access specific data on the disk. It is measured in milliseconds and is an important factor in determining the overall performance of the storage device. Lower seek times indicate faster access to data.
What is a ci module?
A CI (Common Interface) module is a hardware device that allows a digital television or set-top box to decrypt encrypted channels by accepting a conditional access module (CAM) inserted into it. The CAM can be used to access subscription or pay-per-view content that requires decryption. The CI module provides the necessary decryption keys to access the content.
What is a saline lock?
A saline lock is a device that allows intermittent access to a patient's vein without constantly infusing fluids. It consists of a catheter connected to a port that can be capped when not in use, reducing the risk of infection compared to a continuously running IV line.
Definition of mass-memory unit?
A mass-memory unit is a type of storage device that is used to store large amounts of data in various electronic devices such as computers and digital cameras. It typically has a higher storage capacity compared to conventional memory units like RAM and can retain data even when the device is turned off. Examples of mass-memory units include hard drives, solid-state drives, and memory cards.
What are the chrcharacteristics of group of memory hierarchy at each level?
Registers: Fastest and smallest memory, typically located within the CPU for immediate access to data. Cache: Small and faster memory located close to the CPU, used to store frequently accessed data for quick retrieval. Main Memory (RAM): Larger and slower memory that holds data and instructions currently being processed by the CPU. Secondary Storage (Hard Drive, SSD): Largest and slowest memory that stores data persistently, even when the device is powered off.
What device typically has the fastest transfer rate?
RAM (Random Access Memory) storage devices typically has the fastest transfer rate.
Serial access secondary storage device?
name one access secondary device?
What is DASD?
Direct access storage device
Why can a random access storage device access informaion faster than a sequential storage device?
A random access storage device, like a hard drive or SSD, can access information faster because it allows for direct retrieval of data from any location without the need to read through other data sequentially. In contrast, a sequential storage device, such as magnetic tape, requires the system to process data in order, often resulting in delays as it moves to the desired location. This characteristic of random access significantly enhances speed and efficiency when retrieving specific pieces of information.
What is an online storage device?
Online file storage allows individuals or groups to store files, photos, and documents without use of an external file saving device. Users can access stored information for retrieval anywhere an internet connection is available.
What is most papular sequential access storage device?
magnetic tape
What is the act of reading data from or writing data to a storage device?
access
When referring to storage device's what are the two types of access?
Go on wikipedia
What measures the amount of time it takes a storage device to locate an item on a storage medium?
access time
What is the full form of DASD related to computer?
direct access storage device.
What access mode where the device can locate a data item immediately?
RAM (Random Access Memory) is the fastest fast. But no device can locate a data item exactly immediately.
What resource is allows a hardware device to directly access RAM?
direct memory access (DMA)
