Memory 1

When we hear the word memory, we surely conceive a place for the save of data or instruction. But computer peripheral, memory mean a set appliance arranging or determining program amount which can be run during which same, at one blow how many data amount which can be processed. Others Memory also represent to represent the repository where about program and data to be operated by prosesor. At computer there are four kinds of type memory, that is :
1. Random Access memory (RAM)

RAM Or random access memory is a data repository because we earn at random access all location in memory. Fill from RAM can fluctuate as according to data processed in it, or also program using. RAM represent the computer resource which in character reusable or can be re-used. RAM represent a group of chip capable to accomodate:
>> data to be processed,
>> instruction or program, what is needed to process data,
>> data which have been processed and await to be sent that goodness go to the output device, secondary storage or also communication device,
>> instruction operating system controlling elementary function from computer system.

Depository capacities from RAM very immeasurable in so many this computer caused a data amount which mush accessed or run, capacities excelsior a RAM, progressively stabilize the data to be processed. capacities RAM supposed a dining table, much wide capacities from RAM hence will more and more process which can be run in one time. To understand the capacities from RAM, hence some terminology in the following often used.

>> Bit, that is a binary system binary smallest unit from data in a computer system. A beet only consisted of the two number that is 1 and 0. In computer, a 0 meaning a sinyal electronic or magnetic is the noting or absen, whereas 1 meaning on the contrary.
>> Byte, thai is a gruping of eight bit. A byte deputize one character, one digit or one value. Capacities from memory computer, or RAM expressed in bytes or a group of from bytes.

To arrange a RAM to be can work better, it's needed by a Operating System. Instruction And program kept in RAM in fact kept in the form of corps bits which merepresentasikan data, mentioned program and instruction. This beet kept into a microscopic electronic shares with capacitor.

RAM represent the memory type having the character of volatile meaning data which is there are in RAM will lose permanently it there aren't electrics current, this matter also represent the cause why RAM referred as repository whereas. BecauseRAM have the character of the volatile, hence made of other type memory which can savina data permanently and have the character of the non volatile or data will not be vanished even is not emited a stream of by the electrics current. Memory of this type of often referred as secondary storage, follow the example of from secondary storage for example harddisk, optical disk, and others.

Besides RAM still there are other memory type, that is ROM, CMOS And Virtual Memory to be studied at nest article.
