Hey all, Welcome to Geeksforjobs
Computer memory is a general term for all of the different types of data storage technology. We use this technology on computers. This may include RAM, ROM, and flash memory.
Computer memory works very fast and efficient. Basically, which means that the central processing unit (CPU) can access the data stored there very quickly in a short period of time. Other types of memory can be inexpensive so that we can store large amounts of data in it.
Computer memory also varies on different types, such that they may be non-volatile. Non-volatiles mean that they can store data for a long time, even if there is no power instance ROM. And some types are unstable, which are fast. But it loses all data because the power supply is disconnected from the example RAM.
A computer system consists of a combination of different memories. The exact configuration can be optimized to produce maximum data processing speed and minimum cost.
Types of computer memory
primary and secondary
Primary and secondary memory are different. The basic difference is that system memory consists of primary memory, and storage contains secondary memory.
The key difference between primary and secondary memory is the speed or efficiency for accessing data.
ROM, RAM and Cache are the primary memory and are located in the CPU of the computer motherboard. This enables the CPU to read data from primary memory much faster. It stores the data that the CPU often needs. So, don’t have to wait for that data to be distributed.
Secondary memory is once separated from the primary. Secondary memory is physically located, like a solid state drive (SSD) or hard disk drive (HDD). It is located within a separate storage device. The storage device is directly connected to the computer or directly to the network. Secondary memory costs less than primary memory. But read and write speeds and efficiency are slower than primary memory.
Primary memory type in computer
RAM and ROM
These are the two basic types of primary memory:
RAM, or Random Access Memory
ROM, or read-only memory
Secondary memory type in computer
Secondary memory consists of many different storage media that can be directly connected to a computer system including:
- Hard Disk Drive (HDD)
- Solid State Drives (SSDs)
- Optical (CD or DVD) drive
- tape drive
Other types of storage:
We can connect some storage devices over a traditional network (known as network-attached storage or NAS)
Nowadays cloud storage is in trend. Around 2.3 million of the world’s population uses cloud storage. Cloud storage is efficient, accessible with improved security features.
