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 are the main types of primary memory?
The two main types of primary storage are ROM, which is non-volatile , and RAM, which is volatile . Non-volatile memory keeps its contents even when the computer is switched off. Volatile memory loses its contents when power is lost.
What is 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 are the three types of primary memory?
The primary memory of a computer can be categorized into three major types. viz., a. Main memory that holds instructions and data of the current program, b. Cache memory that enhances the performance of CPU by holding a copy of instructions/data stored in the main memory to save unwanted retrieval, c.
What are the two types of memory?
Memory Types There are two major categories of memory: long-term memory and short-term memory.
Why do we need primary memory?
The operating system and applications are loaded into primary memory, since RAM can be accessed much faster than storage devices. … By loading data into RAM, programs can run significantly faster and are much more responsive than if than constantly accessed data from secondary memory.
What is the difference between primary and secondary activities?
(i) Primary activities include activities, such as hunting, fishing, mining, agriculture. (i) Secondary activities include manufacturing and constructions. (ii)These activities concerned with are obtaining materials directly from nature. For example, fish from water or wood from trees.

What is a primary memory?
Types of Computer Memory: Primary and Secondary The key difference between primary and secondary memory is speed of access. Primary memory includes ROM and RAM, and is located close to the CPU on the computer motherboard, enabling the CPU to read data from primary memory very quickly indeed.
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 is primary memory write its types?
There are two types of memory in primary memory, RAM and ROM. For the IB, you should focus on RAM, and not ROM. RAM is Random Access Memory which loses its contents when the computer is switched off (it is volatile ). This memory can be written to, instructions and data can be loaded into it.
What is an example of 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. … For example, a computer may have a one terabyte hard drive, but only 16 gigabytes of RAM.
