Software refers to the programs and instructions that tell a computer what to do, while hardware refers to the physical components of a computer system, such as the processor, memory, and storage devices. In simple terms, software is the brain of the computer, while hardware is the body.
Software refers to the programs and applications that run on a computer, while hardware refers to the physical components of a computer, such as the processor, memory, and storage devices. In simple terms, software is what you can't touch but interact with on a computer, while hardware is the physical parts that you can touch and see.
Storage technology
Primary storage refers to the main memory of a computer, such as RAM, which is fast but temporary and volatile, meaning it loses data when power is off. Secondary storage, like hard drives and SSDs, is non-volatile and provides long-term data storage, retaining information even without power. Offline storage refers to any storage that is not directly accessible by the computer's operating system, such as external hard drives, USB drives, or magnetic tapes, which can be disconnected and used for backup or transfer purposes. In summary, primary storage is fast and temporary, secondary storage is slower but permanent, and offline storage is external and not directly connected to the system.
Auxiliary storage refers to secondary storage devices that are used to store data and programs not currently in use by a computer's main memory (RAM). Examples include hard drives, solid-state drives, USB flash drives, and optical disks. Unlike primary storage, auxiliary storage is non-volatile, meaning it retains data even when the computer is powered off. It provides larger storage capacity and is essential for data backup and archiving.
Permanent storage refers to data storage solutions that retain information indefinitely, even when not powered, such as hard drives, SSDs, and cloud storage. In contrast, temporal storage, also known as volatile storage, holds data temporarily and loses it when the power is turned off, like RAM. While permanent storage is essential for long-term data retention, temporal storage is crucial for fast access to data that the system is currently using.
KB refers to kilobyte which is a unit of computer storage equal to 1,024 bytes. MB refers to megabyte which is a unit of computer storage equal to 1,048,576 bytes. 30MB equals 30,720KB.
The two names of backing storage are secondary storage and auxiliary storage. Secondary storage refers to non-volatile storage that holds data and programs not currently in use by the computer's main memory, while auxiliary storage encompasses a wider range of devices, including hard drives, solid-state drives, and optical discs. Both types are essential for long-term data retention and retrieval.
the stored information on a disk is permanent only as long as the computer is on
storage refers to the keeping of data and information for later. in computer science there are two types of storage that is primary storage and secondary storage in primary storage data is kept temporary in ROM(read only memory) while in secondary storage data is kept permanently like on hard disk, tape, cds.
To get rid of something; usually refers to text on a computer screen or data on a storage device.
