What is Computer Memory and Types of Computer Memory – Best Information
What is computer memory – Computer memory is one of the main components of a computer system, computer memory has a size limit and can be erased as well as rewritten. Computer memory controls the speed of operations performed by the computer. The speed of working on a spreadsheet program also largely depends on the memory. Computer memory also controls the number of programs that can be operated at a time because each program consumes a fraction of the computer’s total memory.
You must be thinking that how can a computer be such an amazing gadget? How computers have changed the way we live. Computers can now be found in many sizes. It would seem that almost every household appliance has its own mini computer located somewhere. From cars to buildings to almost every gadget, most of the time everyone has a computer that works to drive them and change the way we live our lives.
First and foremost, the most important component of a computer is its processor. It is considered to be the heart of the computer which does all the calculations and processing. But along with computing and processing, the computer would not be such a remarkable gadget if not for its amazing memory. Computer memory makes it possible to retain important information on the computer. Such data can be used repeatedly and retrieved when a certain stored data is needed. Without computer memory, the processor would have no facilities to store its important calculations and procedures, making them useless.
Different types of computer memory are used to store different types of data. They also have different capabilities and specifications when it comes to storing the required data inside the computer. The best part of computer memory is RAM, otherwise known as Random Access Memory. It is called random access because any stored data can be accessed directly if you know the exact row and column that intersect a certain memory cell.
The data in this type of computer memory can be accessed in any order. The exact opposite of RAM is called SAM or serial access memory, which stores data in a series of memory cells that can only be accessed in sequence. It works much like a cassette tape where you have to pass through other memory cells before you can access the data you’re looking for.
Other types of computer memory include ROM or read only memory. ROM is an integrated circuit that is already programmed with specific data that cannot be modified or changed, hence the name “read only”. There is another type of computer memory called virtual memory. This type of memory is common on most operating systems and desktops. It helps to free up computer RAM from unused applications to make way for the current applications to be loaded. It works by checking the data stored in RAM that is not being used recently and is stored in the computer’s hard disk, freeing up valuable space in RAM for other applications to load.
A virtual memory makes a computer think that it has almost unlimited RAM inside. Another type of computer memory that allows a computer to perform tasks is called cache memory. Cache memory only works by storing the current application, calculations, and processes in its memory, and not directly in the main storage area. When a certain process needs previously used data, it will first attempt to access the cache memory if such data is stored there before reaching the central memory storage area.
This frees the computer from looking for data in larger and larger memory storage areas and makes data extraction faster. Computer memory is in a state of constant evolution as more and more technologies are being developed. Who knows, maybe computer memory will also be suitable for human consumption in the near future.
What Is Computer Memory And How Much Do We Need
What is computer memory – with reference to RAM memory. RAM memory is also known as random access memory and it stores the information used by the processor on your computer. RAM memory is made up of a module with integrated circuits on it. Integrated circuits store information in them, and that information can be accessed by the CPU in any form or form, which is why it is called random.
Memory can be accessed in any way without changing or modifying the module. The only problem with RAM memory is that the moment the computer is turned off that memory is lost. Unlike previous data storage methods, RAM memory can pull data from any location within the circuit and other methods such as tape and magnetic discs require a physical volume of data or an optical reading unit.
RAM can also be written to, so essentially it can also read right. The problem is that RAM memory loses its data once the computer is turned off. This is where computer flash memory or ROM memory comes into play.
ROM Memory – ROM memory is a small circuit of memory that is stored on the motherboard itself. ROM memory contains all the data that a computer needs to start up and start up. ROM memory is read only memory, so it cannot be changed and read only, so it usually only holds the firmware that the hardware needs to start up. ROM memory only holds information that is unlikely to change any time soon.
Hard Drive Memory- Most of the people who use computer but don’t understand how computer works or what is computer memory. They think that RAM memory and hard drive space are the same thing. In fact a hard drive is a metal plate that is mounted inside a metal case. The head can read and write information as it rotates. Hence hard drives are used to store long duration and large files which can be accessed in future. Because RAM memory cannot store anything, we use hard drives to store the information that we need to access on some other occasion.
This is a mistake that most people make when referring to hard drives as memory. In fact a hard drive is just a storage device. Now that we have established that hard drive has nothing to do with memory and it is easy to understand the importance of RAM memory in our computer. So when you choose a new computer, you should buy a computer that has maximum RAM memory.
Computer Memory and the Benefits of Flash Memory
Computer Memory – Computer memory is one of the main components of a computer system, computer memory has a size limit and can be erased as well as rewritten. Computer memory controls the speed of operations performed by the computer. This can be explained with an example, i.e. the speed of minimizing and reopening the window depends on the memory. The speed of working on a spreadsheet program also largely depends on the memory. Computer memory also controls the number of programs that can be operated at a time because each program consumes a fraction of the computer’s total memory.
Nowadays, computer memory is considered a highly purchased commodity, but buyers are not fully aware of its functioning. Many of them confuse it with hard disk, hard drive space, processing power and many other storage functions. However data is written to those devices and they remain static on those disks until they are changed and/or erased. Computer memory consists of a small circuit board that is plugged into a suitable socket found on the motherboard. Therefore, it is believed that it is very easy to upgrade and replace the memory.
Flash memory can be considered an important part of available storage media and is referred to as non-volatile computer storage that can be electrically erased and reprogrammed into larger blocks. This technology was mainly used in USB flash drives and memory cards. Flash memory proved to be very beneficial for computers and computer memory as it helps to store data and then transfer that data to the computer through other digital products and devices.
Many computer flash memory cards are available with different sizes of storage capacity which have been running very successfully and as a result users of computers as well as digital product users such as digital audio players, mobile phones and digital cameras.
Different Types Of Computer Memory
The most common and most commonly used computer memory is your RAM which stands for Random Access Memory. Random access memory is considered as random access because you can access any cell of the memory for retrieval or storage of any information at any time if you know the row and column in that cell. For example: Suppose we are working on an Excel spreadsheet and we want to change the value in cell A1 from 100 to 90. To do this the computer needs to know where the contents of that cell are located on the RAM chip. Fortunately for the user, it does, and the user does not have to do it.
Once the change is made, the computer replaces the content in RAM, which was the value 100, with the new value of 90 and leaves it in that location until the user decides to change the value again. or does not close the spreadsheet. Once this happens, the contents of that particular location in the RAM are lost. The user is expected to have saved their spreadsheet to their computer’s hard drive before doing so.
RAM can also be divided into different types. The first is SRAM, which is Static Random Access Memory. This type of memory is usually used for the computer’s cache memory. Next is DRAM, which is Dynamic Random Access Memory. This type of memory consists of memory cells with coupled transistors and capacitors that require constant refreshing. Next is EDO DRAM which is Extended Data Out Dynamic Random Access Memory.
It is very fast memory that does not wait until the processing of the first bit is completed before moving on to the next bit. This type of memory takes advantage of the fact that in most cases the data that needs to be accessed is stored sequentially and therefore a much faster method of accessing this memory is used. The rate of this memory is around 528 Mbps, which is extremely fast.
Opposite the RAM is the SAM or Sequential Access Memory.. This is memory that has to be accessed sequentially, one cell at a time until the location the user is looking for is found. This memory is great for buffered memory because the items stored in the buffer are usually stored sequentially anyway as the user continues their work.
Another type of memory is what is known as ROM or read only memory. Read only memory is also known as firmware. It is an integrated circuit which is programmed with some data when it is manufactured. ROM is used not only in computers but in many electronic devices such as your Xbox or any video game console box. Almost any electronic item today that has built in function simply wouldn’t work without ROM.
There are many other types of memory but these are the most common. In future articles, we’ll go into more depth about how memory works in your computer and other devices.
