What are the memory devices of a computer?
RAM
- Static RAM (SRAM)
- Dynamic RAM (DRAM)
- MROM (Masked ROM)
- PROM (Programmable Read Only Memory)
- EPROM (Erasable and Programmable Read Only Memory)
- EEPROM (Electrically Erasable and Programmable Read Only Memory)
- Advantages.
- Disadvantages.
What are the 2 memory devices?
There are mainly two types of semiconductor memory: random-access memory (RAM) and read-only memory (ROM). RAM is a temporary data storage domain, whereas ROM serves as a semi-permanent storage domain.
What are the two types of memory used in a computer?
There are technically two types of computer memory: primary and secondary. The term memory is used as a synonym for primary memory or as an abbreviation for a specific type of primary memory called random access memory (RAM).
What are the types of memory and storage devices?
What is a storage device?
- Hard Disk Drive (HDD)
- Solid State Drive.
- Random Access Memory (RAM)
- CD, DVD and Blu-Ray Discs.
- DVD-RAM.
- ROM.
- USB Flash Memory.
What are the four storage devices?
How is information stored in a memory device?
The memory from which we can only read but cannot write on it. This type of memory is non-volatile. The information is stored permanently in such memories during manufacture. A ROM, stores such instruction as are required to start computer when electricity is first turned on, this operation is referred to as bootstrap.
What kind of memory is used in a computer?
Dynamic RAM is the commonly used RAM in the computers. Unlike earlier times when the computers used to use single data rate (SDR) RAM, now they use dual data rate (DDR) RAM which has faster processing ability. DDR2, DDR3, DDR4 are the available versions of the DRAM each efficient according to their number.
Which is memory device can be modified only once?
PROM is read-only memory that can be modified only once by a user. The user buys a blank PROM and enters the desired contents using a PROM programmer. Inside the PROM chip there are small fuses which are burnt open during programming.
Which is memory device supports the re-programming process?
Hence, the process of re-programming is flexible but slow. Sequential access means the system must search the storage device from the beginning of the memory address until it finds the required piece of data. Memory device which supports such access is called a Sequential Access Memory or Serial Access Memory.
