PENGERTIAN ROM DAN JENIS-JENISNYA BESERTA CONTOHNYA
ROM stands for Read Only Memory, which is hardware in the form of computer chip semiconductor memory whose contents can only be read. ROM can not be classified as RAM, although both have in common that can be accessed randomly (random) .ROM different from RAM.The difference between the two, among others:
1. ROM can not be filled or write the data at any time as RAM. Charging or writing data, information, or program in the ROM requires a special process is not as easy and as flexibly how to write RAM. Typically, data or programs that are written on the ROM filled by factories that make them. ROM is generally used to store firmware, the software associated with hardware. Examples of this kind is the ROM BIOS ROM. ROM BIOS contains the basic program a computer system that serves to organize and prepare all equipment or components or installed on the computer when the computer is "turned on / on '.
2. Information / data / programs that are written on the ROM (ROM contents) is permanent and not easily lost and not easily changed even though the computer 'turned off' or off (off). While in RAM, all of its contents (either in the form of data, programs or information) will disappear by itself if the computer is 'switched off' (in the off state).
3. ROM can store data without the need for power. That is why the data in ROM will not be lost even if the computer is off. While RAM requires power in order to store the data, if the RAM is not getting power, by itself would not be able to store data. This is what causes the data contained in RAM will automatically disappear when the computer is off (off).
4. Modern ROM is often found in the form of IC (Integrated Circuit), the same as his form Yag RAM also mostly in the form of IC. Text or code written in both types of IC is different. IC ROMs usually have a code text (text) 27xxx. Figures 27 shows the code to ROM, while ROM capacity dalan menjunjukkan xxx units kilo bits.
function ROM
As has been previously disclosed that the ROM is generally used to store firmware. On the computer, are often found to store the BIOS. At the moment a computer is turned on, the BIOS can be directly executed quickly, without having to wait for a turn on the first storage device sepRead Only Memory is a hardware form of memory that can only be read. At the ROM, we can not fill or write the data at any time as the RAM. although both are equally accessible acak.memori this type is slower, but the data in ROM will not be lost and not be changed while the computer is off / off because ROM can store data without requiring electrical power. The modern form of the ROM is frequently found in bentu IC (integrated circuit). Function than the ROM is the storage of firmware, the software (software) associated with the hardware (hardware). such as the ROM BIOS, the BIOS which can be directly executed quickly, without having to wait for a turn on the first storage media devices such as would occur in other storage devices. Although the ROM memory as read-only, but the data on this memory can be rewritten.
Read-only Memory (ROM) is an English term for computer data storage medium. ROM stands for Read-Only Memory, ROM is one of the computer's available memory. This ROM is permanent, meaning the program / data stored in ROM is not easily lost or changed while power failure.Storing data on the ROM can not be done easily, but the read data from ROM is easy. Usually the program / data in ROM is filled by factories that make them. Because of these properties, the ROM is used to store the firmware (software that is closely related to hardware).One example is the ROM BIOS ROM which contains the basic program a computer system set up / prepare all equipment / components in the computer when the computer is turned on.Modern ROM found in the form of IC, exactly as the storage medium / other memory such as RAM. To distinguish it needs to read the text that appears on its IC. Usually starts with 27xxx, number 27 indicates the type of ROM, xxx indicates the capacity in kilo bits (not kilo bytes).
Some ROM type:
Mask ROM is a ROM that can not be rewritten (non-flashable), so there can be up-grade.
PROM (Programmable Read Only Memory) is a type of ROM read-only data. PROM classified as non-volatile memory, the data / information / program that will not disappear even if your computer is switched off / off (do not get electric power). so the data contained in this memory is permanent
EPROM (Erasable Programmable Read Only Memory) is a type of memory writeable ROM program / data electrically. Data / information / program may be lost / deleted when exposed to ultraviolet light. EPROM including non-volatile memory, together with PROM, the data will not be lost when the computer turn off / not got power.
EEPROM (Electrically Erasable Programmable Read Only Memory), the same as PROM, and EPROM, EEPROM is still relatively non-vilatile.
EEPROM is a component that is widely used in electronic equipment fatherly store configuration data. EEPROM capacity is limited, the system hardware typically used to store configuration data and settings related BIOS. penghausan process data at faster than EPROM EEPROM for data can be electrically erased with ultraviolet light. Rewrite EEPROM is a tool to delete the data in the EEPROM. Examples of memory similar to EEPROM is Flash Memory. That type of ROM that can be rewritten. Typically used in digital cameras, Mp3 applications, mobile phones, flash, etc. erties common to other storage devices other than ROM.
Generally, on other storage media, if executed to read the contents or data, the storage media must be turned on first before read, which of course takes a little longer. Things like this do not happen in the ROM.
On a computer (PC) modern, stored in the BIOS ROM chip electrically re-writeable known as Flash ROM. That is why the term is more popular than the flash BIOS ROM BIOS
