What is the secondary memory?
Secondary memory refers to storage devices, such as hard drives and solid state drives.
It may also refer to removable storage media, such as USB flash drives, CDs, and DVDs.
Unlike primary memory, secondary memory is not accessed directly by the CPU..
What are the four types of secondary memory?
Secondary memory has four categories like as Magnetic Storage, Optical Storage, Flash storage, and Online Cloud System.
What is the other name of secondary memory?
Secondary memory is also termed as external memory and refers to the various storage media on which a computer can store data and programs. The Secondary storage media can be fixed or removable.
What is primary and secondary memory with example?
Primary memory is the main memory of the computer system. Accessing data from primary memory is faster because it is an internal memory of the computer. All secondary storage devices which are capable of storing high volume data is referred to as secondary memory. Types of Primary Memory 1) RAM, 2) ROM.
What are the characteristics of storage?
Characteristics of storageNon-volatile memory. Will retain the stored information even if it is not constantly supplied with electric power. … Volatile memory. … Dynamic random access memory. … Static memory. … Read/write storage or mutable storage. … Read only storage. … Slow write, fast read storage. … Random access.More items…
Is a secondary device?
Alternatively referred to as external memory, secondary memory, and auxiliary storage, a secondary storage device is a non-volatile device that holds data until it is deleted or overwritten.
What are the 4 characteristics of secondary storage?
Factors affecting the choice of a secondary storage device include:speed (how quickly data can be accessed)cost per storage unit (i.e. price per gigabyte or megabyte)durability (toughness)portability (how easy it is to move it from one computer to another)
What are the difference between primary and secondary memory?
Primary memory is directly accessible by Processor/CPU. Secondary memory is not directly accessible by the CPU. … The memory devices used for primary memory are semiconductor memories. The secondary memory devices are magnetic and optical memories.
What is main memory give an example?
The main memory is defined as the central storage in a computer. An example of the main memory is where programs and data are kept. Main memory is the primary, internal workspace in the computer, commonly known as RAM (random access memory).
What is a secondary explosive?
What are secondary explosive devices? Secondary explosive devices are bombs placed at the scene of an ongoing emergency response that are intended to cause casualties among responders.
What is the main memory define its characteristics?
Main memory is as vital as the processor chip to a computer system. Fast systems have both a fast processor and a large memory. processor is actively working with. … Used for long term storage.
What is the difference between primary secondary and tertiary storage devices?
Primary storage in a form of magnetic memory, or core memory, core rope memory, thin-film memory and/or twistor memory. Tertiary (e.g. NCR CRAM) or off line storage in the form of magnetic cards. Magnetic tape was then often used for secondary storage.
What are the three characteristics of memory?
The key characteristics of memory devices or memory system are as follows:Location.Capacity.Unit of Transfer.Access Method.Performance.Physical type.Physical characteristics.Organization.
Is ROM a secondary memory?
ROM is a type of non-volatile memory, which means that the data stored in ROM persists in the memory even when it receives no power – for example when the computer is turned off. In that sense it is similar to secondary memory, which is used for long term storage.
What are the three types of secondary memory?
There are three main types of secondary storage in a computer system:solid state storage devices, such as USB memory sticks.optical storage devices, such as CD, DVD and Blu-ray discs.magnetic storage devices, such as hard disk drives.
What is a secondary device?
Secondary storage technology refers to storage devices and storage media that are not always directly accessible by a computer. Examples of secondary storage devices include external hard drives, USB flash drives, and tape drives. …
What are the two types of secondary memory?
Depending on whether secondary memory device is part of CPU or not, there are two types of secondary memory – fixed and removable.
What is secondary and primary storage?
Primary versus Secondary Storage. Primary memory usually refers to Random Access Memory (RAM), while secondary storage refers to devices such as hard disk drives, solid state drives, removable “USB” drives, CDs, and DVDs. …
