What is an example of a secondary activity?
Activities associated with the secondary sector include metal working and smelting, automobile production, textile production, chemical and engineering industries, aerospace manufacturing, energy utilities, engineering, breweries and bottlers, construction, and shipbuilding..
What is primary memory?
Primary memory is computer memory that is accessed directly by the CPU. This includes several types of memory, such as the processor cache and system ROM. … RAM, or random access memory, consists of one or more memory modules that temporarily store data while a computer is running.
Is ROM is a secondary memory?
Computer memory is of two basic type – Primary memory(RAM and ROM) and Secondary memory(hard drive,CD,etc.). … Random Access Memory (RAM) is primary-volatile memory and Read Only Memory (ROM) is primary-non-volatile memory.
What are the two types of secondary memory?
Secondary memory is where programs and data are kept on a long-term basis. Common secondary storage devices are the hard disk and optical disks. The hard disk has enormous storage capacity compared to main memory. The hard disk is usually contained inside the case of a computer.
What is an example of secondary memory?
Thus, secondary storage is significantly slower than primary storage. Rotating optical storage devices, such as CD and DVD drives, have even longer access times. Other examples of secondary storage technologies include USB flash drives, floppy disks, magnetic tape, paper tape, punched cards, and RAM disks.
Is ROM a primary or secondary storage device?
ROM: Unlike RAM, Read Only Memory (ROM) is both a non-volatile and permanent form of primary storage. ROM retains its contents even if the device loses power. You cannot change the data on it, but rather just read it.
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. Fixed Storage media is an internal storage medium like hard disk that is fixed inside the computer.
What are examples of primary activities?
The primary sector of the economy extracts or harvests products from the earth such as raw materials and basic foods. Activities associated with primary economic activity include agriculture (both subsistence and commercial), mining, forestry, grazing, hunting and gathering, fishing, and quarrying.
What are the main types of primary memory?
Primary storage is a key component of a computer system that enables it to function. Primary storage includes random access memory (RAM), read only memory (ROM), cache and flash memory. Each of these have different uses within the computer.
What is primary and secondary memory with example?
Secondary memory refers to storage devices, such as hard drives and solid state drives. … While secondary memory is much slower than primary memory, it typically offers far greater storage capacity. For example, a computer may have a one terabyte hard drive, but only 16 gigabytes of RAM.
What is the difference between primary and secondary activities?
(i) Primary Sector (or Agriculture sector). It includes all those economic activities which are connected with extraction and production of natural resources, e.g., agriculture, fishing, mining, etc. (ii) Secondary Sector (or Industrial sector). … It facilitates smooth flow of goods and services in the economy.
What are primary and secondary devices?
A computer’s internal hard drive is often considered a primary storage device, while external hard drives and other external media are considered secondary storage devices. … RAM, commonly called “memory,” is considered primary storage, since it stores data that is directly accessible by the computer’s CPU.
What are the 5 types of memory?
Memory TypesLong-Term Memory. Long-term memory is our brain’s system for storing, managing, and retrieving information. … Short-Term Memory. … Explicit Memory. … Implicit Memory. … Autobiographical Memory. … Memory & Morpheus.
What is the use of primary memory?
Primary memory is computer memory that a processor or computer accesses first or directly. It allows a processor to access running execution applications and services that are temporarily stored in a specific memory location. Primary memory is also known as primary storage or main memory.
What is the main difference between primary and secondary memory?
Computer memory is categorized into 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.
What are two types of primary memory?
Primary Memory Types: RAM and ROM There are two key types of primary memory: RAM, or random access memory. ROM, or read-only memory.
What is primary memory with example?

What is the difference between primary secondary and tertiary activities?
Each sector is interdependent on the other so that the economy as a whole functions properly and efficiently. The primary sector is where the materials for the secondary sector are gathered. In the secondary sector, the product is then made into consumable item(s) which is then distributed by the tertiary sector.
