Types of Computer Memory

Computer Memory stores or saves instructions and results, the results can be saved permanently as well as temporarily. The data or instruction once saved can be retrieve or recall or review whenever user demands.

They can store huge amount of data and information as per requirements. The user can use the data whenever needs. The Computer Hard Disk used as a memory has the capabilities for storing volumes of data such as songs, movies, pictures, software’s one can easily get access to this data whenever or wherever user demands. Users can be rest a sure of their data, as the data is stored almost permanently.


Internal Processor Memory :

This tiny high speed registers which lives internally in a CPU or Processor, these registers are used and utilized in storing the data or instruction and information temporarily before the data is processed further where real processing and preparing takes place.

These registers are placed inside ALU and control unit, they are high speed which performs arithmetical and logical operations in enormous speed, they stores or hold the data or instructions and information temporarily during the process, registers are extremely efficient.

Primary or Main Memory :

Primary or Main Memory is additionally called as “SEMICONDUCTOR MEMORY”. This is likewise a Temporary memory which holds or saves data and information temporarily, as when there is a power failure or no power the data or information is lost. They work or hold only on the present data which is being used and utilized by a computer system. They are not as fast as the registers.The semiconductor memory is faster, smaller, lighter and they consume less power Compared to secondary storage. They have a limited capacity, as well as they are very costly and can store only a couple of bytes of data.

They are essential memories to a computer as if they removed from a computer it fails to start or boot normally. Each and every computer needs primary memory to work properly. The Capacity of primary memory is calculated in MB (Mega-Bytes) and GB (Gega-Bytes).nowadays They come in huge capacities ranges from 2 GB to 16 GB.

The main memory is further classified into two categories :

RAM (RANDOM ACCESS MEMORY)
ROM (READ ONLY MEMORY)

The RAM Is known as “Random Access Memory”. This is a volatile memory that means it cannot stores or saves the data or instruction or set of information once the power is off. They are fast, less expensive & light. Ram can transfer or exchange data from and to CPU considerably speedier than secondary storage. The RAM is placed inside the computer system to be precise they are installed on a computer motherboard and it is also a primary reason for computer speed. It is used for storing all active programs or instruction with a goal that it can be additionally exchanged to CPU for the additional process.

Ram is divided into two more categories :

Static Ram
Dynamic Ram

Static RAM : The static Ram stores binary information in clocked sequential circuits. It is comprised of flip-flops and stores a touch of voltages. It is a volatile or unstable memory if the power is from the data or instructions are destroyed. This kind of memory does not require refreshing.

Dynamic RAM : Dynamic RAM stores binary information in the form of electric charges that are connected to capacitors which are inside the chip. This type of Ram Consume less power and are capable of storing or holding more data and information compared to static RAM.

ROM Stands for “READ ONLY MEMORY” they are non-volatile or non-unstable if the power is off it can still store the data permanently. They can be used as a permanent storage.Users can not manipulate the data which is inside this memory only the manufacturer or programmers writes programs or instruction inside them .which are used to boot the computer or operating systems when computer is powered on.

ROM are of different Types :

PROM
EPROM
EEPROM

PROM stands for “Programmable Read Only Memory” it is also a type of non-volatile memory .which once programmed or customized then the set of instruction or information Stored cannot be deleted or updated or refreshed. Computer Programmers or software developers write and compose program or codes in this chip in such a fashion to receive the desired functionality, special equipment are used to write programs inside the chip.

EPROM stands for “Erasable Programmable Read Only Memory” as the name suggest the programs which had been written and composed by computer programmers can be Deleted or updated or changed according to the necessities. One simply need to uncover this chip to High Ultraviolet light for over 20 minutes to delete the information. Once exposed they can be reused after Reprogrammed

They should not be overexposed to avoid damage.You cannot delete, erase a single content from them as if you try to do it the whole data or information inside the chip gets deleted or erased. This type of memory are broadly used as they are cheap and reliable.

EEPROM stands for “Electrically Erasable Programmable Read Only Memory” to erase or delete the information or data inside them one should take the memory outside the PCB (Printed Circuit Board).As the time required for erasing the information is significantly more speedier the EPROMs.

How much is the largest memory capacity of RAM or ROM in computers nowadays?

Does a Ram contain both Static and Dynamic? or just one of them?

bakit bawas yung rom sa cp?

If all of the programs run in RAM, why does a full hard disk kill performance?

Because the more memory on the drive the more heat it will generate while processing requests. When you're running the controllers near max the heat will deprecate the performance.

I learned about types of memory in school a few months ago and i understood it decently, but this post fortified my understanding! Thanks

Why can't ALL explanations be this simple, easy to understand, user friendly? This post was great!

If more computer memory is better, does it imply that clock speeds really don't mean much anymore?

Nopee, faster cores make everything faster, more cores don't.

So clock speed is what matters most.

Hmm I think for server use, specifically data mining and virtual hosts, the more cores and threads the better.

If that is a problem for you guys, just switch to comparing the 4004's speed and performance VS a single core of a modern processor.

yes

How is computer memory measured?

The basic unit of measurement for memory size is the bit. A bit is either a 0 or a 1.

The reason why RAM must remain powered on is not because of its random access pattern, but because it's a form of volatile memory.

true
