A buffer is a temporary storage area used to hold data being transferred between two devices that operate at different speeds. It ensures smooth data processing and prevents bottlenecks.
In computer terminology, 'burn' refers to the process of recording information onto an optical disc such as a CD, DVD, or Blu-ray. This action physically etches or inscribes the data onto the medium using a laser.
A byte is the amount of computer memory space needed to store one character, which is typically 8 bits. A computer with 8-bit bytes can distinguish 2^8 = 256 different characters. The size of a computer's memory is measured in kilobytes, where 1 kilobyte (KB) = 1024 bytes.
A cache is a storage location that holds frequently accessed data to speed up future retrievals. It is commonly used in computing to improve performance by reducing the time to access data.
CD-ROM stands for Compact Disc Read-Only Memory, a type of optical disc that stores data for computers in digital form, similar to audio CDs. They are commonly used for distribution of software, multimedia applications, and data storage.
A cell is the intersection of a row and a column in a table, particularly within a spreadsheet. It serves as the basic unit for storing data in programs such as Microsoft Excel, Google Sheets, and other spreadsheet applications.
The clipboard is a temporary storage area in a computer's memory used for storing text, images, and other data that are cut or copied from a document. Both Macintosh and Windows operating systems support this feature.
Cloud computing offers a modern approach to computing where end users connect to a network of remote servers to run applications, store data, and leverage computing power, enhancing accessibility and reducing the need for local infrastructure.
A small file downloaded to your computer when you browse a web page. Cookies hold information that can be retrieved by other pages at the site.
Customer Relationship Management (CRM) involves the practice of storing, analyzing, and utilizing data gathered from various customer interactions, including sales calls, customer service centers, and actual purchases, to gain a better understanding of customer behavior and enhance customer relationships.
Data refers to the information that is processed, stored, or produced by a computer. The distinction between program (instructions) and data is a fundamental concept in computing.
A Data Flow Diagram (DFD) is a graphical tool used to illustrate the flow of data through a computer system, highlighting its processes, data stores, and data sources/destinations.
Database Management refers to the methodology of storing, manipulating, and retrieving data within a database, encompassing tasks such as data entry, classification, modification, updating, and output reporting.
A Database Management System (DBMS) is a software system that uses a standard method to store and manage data. It allows users to define, create, maintain, and control access to the database.
A computer memory device consisting of a platter with a magnetically encoded surface that retrieves data by being spun past read heads. Disks can be internal (hard disks) or removable. A common example is the Compact Disc (CD).
Device that enables a computer to read and write data on disks, serving as a core component for data storage and retrieval.
A DVD (Digital Versatile Disc or originally Digital Video Disc) is an optical disc storage format capable of storing large amounts of data, far greater than that of a CD-ROM.
Events accounting is a method of accounting wherein data is stored and reported based on specific events, rather than being organized chronologically or by other methods.
A 'file' can refer to the act of organizing material for easy retrieval, a collection of stored information on a computer, or the formal submission of a document.
A fixed disk, also known as a hard disk, is a data storage device used for storing and retrieving digital information.
A flash drive is a data storage device that uses flash memory to store data persistently. It incorporates a USB interface for easy connection to various devices and has replaced many other storage formats due to its portability and ease-of-use.
Flash memory is a type of non-volatile computer storage chip that can be electrically erased and reprogrammed. It is commonly used in devices such as memory cards, USB flash drives, MP3 players, and solid-state drives for data storage and transfer.
A floppy disk is a thin, flexible plastic disk with a magnetic coating, usually encased in rigid plastic, once popular for computer data storage and transfer. It has been largely supplaneously to compact discs, memory cards, and USB drives.
A hard disk, also known as a drive, is a computer storage medium that uses rigid aluminum disks coated with iron oxide. Hard disks have much greater storage capacity than removable media such as floppy disks and CDs.
A hard disk, also known as a hard drive or HDD, is a data storage device used to store and retrieve digital information using magnetic storage.
A Hard Disk Drive (HDD) is a data storage device used for storing and retrieving digital information using one or more rigid rapidly rotating disks coated with magnetic material.
Internal storage refers to the memory that is built into a computer system, enabling the storage and retrieval of data and applications required for the computer's operation.
A kilobyte (KB) is a unit of digital information storage, commonly used to describe the size of files, memory capacity, and other data storage elements. One kilobyte equals 1,024 bytes in most contexts.
Primary storage devices, such as Random Access Memory (RAM), are where current data is stored temporarily as the computer operates. These devices use volatile memory chips to manage active processes and data.
A punch card is an index card with holes punched in predefined positions to represent data or instructions. Widely used in the 1960s for inputting information into computers, punch cards have since become obsolete, replaced by more advanced interactive terminals and input devices.
Random-Access Memory (RAM) is a type of computer memory that can be accessed randomly; any byte of memory can be accessed without touching the preceding bytes. RAM is the most common type of memory used in computers and other electronic devices to store data temporarily that the CPU needs while performing tasks.
Random-Access Memory (RAM) is a crucial component in computers and other digital devices. It is a form of volatile memory that temporarily stores data for quick access, significantly impacting the system's performance and capacity.
Records Management refers to a system used to collect, record, store, and eventually discard information. Effective records management ensures that information is correctly managed throughout its lifecycle, supporting compliance, operational efficiency, and risk management.
The term 'save' refers to the act of setting aside resources for future use, particularly in the context of finances and data storage.
Standing data refers to information stored in a computer system for long-term use because it does not frequently change. An example is the names and addresses of clients.
