Internal and External Memory Internal memory is normally associated with RAM (Random Access Memory) and is also known as main memory. It is typically smaller in size but has faster access times. External memory, also known as secondary memory, is separate from main memory.

The term memory refers to the amount of RAM installed in the computer, whereas the term storage refers to the capacity of the computer's hard disk. ... Here's another important difference between memory and storage: the information stored on a hard disk remains intact even when the computer is turned off.

Phone's memory includes RAM and ROM. RAM equals the memory (or memory bar) of the computer, while ROM is the device's internal storage, equaling the hard disk of the computer. The bigger the RAM, the more software the phone runs smoothly; While the bigger the ROM, the more data it can store.

What are the types of internal memory? There are basically two kinds of internal memory: ROM and RAM. ROM stands for read-only memory. It is non-volatile, which means it can retain data even without power.

Main memory or real memory is the memory that is physically present. It is the memory which all the processing units of a computer have direct access to. ... Virtual memory is a concept where you can run those program whose size is more than your RAM size..

The memory of a computer is classified in the two categories primary and secondary memory. Primary memory is the main memory of the computer where the currently processing data resides. The secondary memory of the computer is auxiliary memory where the data that has to be stored for a long time or permanently, is kept.

An internal bus enables the communication between internal components, such as a video card and memory. An external bus is capable of communicating with external components, such as a USB or SCSI device.

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.

Difference between Primary Memory and Secondary Memory. ... Primary memory is the main memory of the computer which can be directly accessed by the central processing unit, whereas secondary memory refers to the external storage device which can be used to store data or information permanently.

The basic difference between the direct and indirect addressing mode is that in the direct mode, the memory location is directly specified. On the contrary, in the indirect addressing mode, the address of the main memory location is specified.

The differences between ROM (Read Only Memory) and RAM (Random Access Memory) are: ROM is a form of permanent storage, while RAM is a form of temporary storage. ROM is non-volatile memory, while RAM is volatile memory. ROM can hold data even without electricity, while RAM needs electricity to hold data.

First off, the main difference between an internal drive versus and external one is this: internal hard drives are installed within the body (laptop) or tower (desktop) of your computer, while external hard drives connect to your computer via a USB or FireWire connection.

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. ... Along with a faster CPU, every new model of computer seems to come with more main memory.

1 Answer. In internal sorting all the data to sort is stored in memory at all times while sorting is in progress. In external sorting data is stored outside memory (like on disk) and only loaded into memory in small chunks. External sorting is usually applied in cases when data can't fit into memory entirely.

Difference between Primary and Secondary Memory While primary memory is the main memory of the computer which is used to store data or information temporarily, whereas secondary memory refers to external storage devices that are used to store data or information permanently.

The main difference between physical and virtual memory is that the physical memory refers to the actual RAM of the system that stores the currently executing programs, but the virtual memory is a memory management technique that allows the users to execute programs larger than the actual physical memory.

Storage. Whereas memory refers to the location of short-term data, storage is the component of your computer that allows you to store and access data on a long-term basis. Usually, storage comes in the form of a solid-state drive or a hard drive.
