RAM Definition :
RAM Definition (Random Access Memory) is hardware in a computer that functions as a temporary data storage (memory) and various program instructions.
RAM contents can be accessed randomly or not depending on layout settings. Data in RAM can be deleted by the computer deactivated or the power supply is removed from the device.
RAM capacity in a computer determines the speed of data processing or loading on the computer. Improving the process of storing data, opening data, and running programs, will be faster according to the RAM of the computer.
RAM function :
As requested in the RAM settings above, RAM functions in general to read and store data. Here's the explanation :
1. Read Data
All data and information stored on the hard disk can be opened more quickly because of the role of the RAm computer.
Try comparing the speed of loading a new file or program first accessed with a file when or the program has been opened before. When the program or file is opened, then the data is read and stored in RAM while it will be opened faster and the computer has not been shut down.
2. Temporary Storage
RAM can also be used as a temporary data storage when a program on a computer is running. So, our compilation makes something, for example making a paper, then the computer will store temporary data.
However, the data must be issued to avoid damage or loss due to unexpected things. For example, outages or a surge in electric current that is not stable.
Types of RAM :
The following are some types of RAM :
1. Dynamic RAM (D RAM)
Dynamic RAM is a type of RAM that is refreshed (refreshed) by the CPU (Central Processing Unit) on a regular basis so that the data in it is not lost.
2. SD RAM
SDRAM (Dynamic Random Access Dynamic Memor) is RAM received from DRAM but has been approved by the clock system. Cheaper than DRAM.
3. DDR RAM
DDR RAM (Double Rate Random Access Memory) or often referred to as DDR only, namely the type of RAM with the next technology and from SD RAM. DDR RAM also has the latest generation, namely DDR2 and DDR3 and the possibility will continue.
4. RDR RAM
RDR RAM (Rambus Dynamic Access Memory) is a type of RAM that processes faster and more expensive than SD RAM. SD type RAM used on computer devices that use Pentium 4.
5. S RAM
S RAM (Static Random Access Memory) is a type of RAM that can store data in refresh / refresh from the CPU. This type of RAM is faster than D RAM and SD RAM.
6. EDO RAM
RAM EDO (Extended Data Out Random Access Memory) is the type of RAM used on devices with OS Pentium. This type of memory can save and retrieve data at the same time.
ROM Understanding :
Definition of ROM (Read Only Memory) is a type of memory or data storage in a computer that is permanent so it is not easily changed or lost.
ROMs included in the group of computer hardware consist of semi-conductor memory chips while their contents can only be read only to store data in ROM practically not easy. Usually ROMs contain programs that are default from the factory so they are used generally to store firmware.
How ROM works
In accordance with the ROM (Read Only Memory) definition above, the working principle of ROM in a computer device is actually very simple. The owner of the computer device will send the published data containing the factory default software to the ROM chip.
Furthermore data in ROM will still be the output device. Please note that you cannot tamper with the contents on ROM and ROM can only be filled once during use.
ROM Function (Read Only Memory)
As a storage medium, ROM functions to store firmware that uses software or often called software. Software that normally fills ROMs associated with hardware such as ROM BIOS (Basic Input Output System).
The BIOS will turn on automatically when the computer is turned on without the need to disable storage media like other memory systems such as RAM. Related to the speed of access, media ROM is faster than other storage media.
On modern computer devices, the BIOS is stored in ROM chips which have been previously provided which are rewritten or called flash ROMs.
ROM Types
Because it is not easy to change and is not easily lost as explained in terms of ROM (Read Only Memory), the storage system in ROM is currently often used by alternative companies to store confidential documents or important documents. Some types of ROM commonly used include :
1. Stock ROM
This is a type of ROM which is an operating system in the default form and has not yet been modified.
ROM stock contains configuration and display that is still the factory standard and has not changed much from the developer. Usually this type of ROM is found on Apple IOS devices and Palm WebOS.
2. Special ROM
For this type of ROM, it is very suitable for storing important company data because it can be adjusted or used alone. Custom ROMs are often used by independent developers who like to tinker with computer devices.
This Custom ROM is developed directly from Google through the OS it has which is also commonly found on Android devices.
3. Manufacturer ROM or Carrier Stock
The third type can also be called a Carrier Stock ROM that has been changed from the factory or network operator.
Changes to ROM like this are intended to give approval to the application. Popular types of ROM are rarely found on PC devices, and vice versa are more often applied to Android devices.
So, reveal about the definition of RAM and ROM related to the function and types. May be useful.
