Types Of Memories In Computers
Memory is considered to be one of the most essential parts incorporated in the computers, laptops, and PCs. There are different types of memories in computers which can be installed depending on the literal need for the functioning as well as stipulation of the system. The memory is used in holding the information which is stored in the computer. The most general type of memories in computers is of RAM, which is basically located within the computer and is quickly accessed by the CPU. The data stored in the RAM is normally loaded from the hard disk of the computer and consists of the information related to OS and several apps. However, in case of overloaded RAM, the computer works at a relatively slow speed.
ROM is the type of memories in computer which is considered to be very active and is a type of non-volatile storage memory. Nevertheless, the subject in this type of memory can’t be modified or altered. The hard disc drive is considered to be the long term memory of the computer and is used to store different data, games, photos, and music etc. The hard drives actually work internally like a record and the information in it is stored in the sign of small regions. The hard discs are the type of memories in computer that can store almost two or even more terabytes.
Flash memories are considered to be a non-volatile types of memories in computers and are even stable without any sort of power. The information in this type of memory is actually stored in the form of a large number of floating gate transistors. Flash memory is considered to be very long-lasting and it can normally survive every kind of rough and tough handling. In addition, the flash memory is even capable of bearing the immersion in water. This proves to be very helpful for the portable use of flash memory, however this memory is considered to be comparatively slow.
Tape drives are the types of memories in computers that function like that of an audio cassette. The tape drives are used by large systems for long-term as well as static storage. The compact disk read only memory or CDROM, and it is considered to be very appropriate for a portable storage. DRAM is the type of computer memory which is typically used in personal computers and the access time of this memory is less than 60 nanoseconds. In the same way, DRDRAM is a new type of RAM and the access time of this memory is almost 20 times quicker than that of DRAM.
PROM or programmable read only memory is the type of memory that basically acts like that of a ROM and it consists of two types: EPROM and EEPROM. EPROM is the type of memory that can easily be erased as well as altered by the consumer. On the other hand, the EEPROM is the type of memory which is non-erasable and can’t be altered after being programmed.
