RAM is a moniker for Random Access Memory. It acts as a short-term memory much like the human brain to store a wealth of information. The RAM is accessible through the computer's brain called the CPU which stands for Central Processing Unit. RAM has the capability of being retrieved only while a computer is on. When the computer is turned off the RAM is no longer accessible. ROM chips along with BIOS (computer boot firmware) allows the RAM information to be retrievable when the computer is rebooted.
RAM size and Location on the Computer System
Most computers come equipped with 256 million bytes of RAM already on the computer. Additional RAM can be placed within the system. However, there is usually a limitation placed upon just how much RAM can be added to a computer system. RAM is not random as its name would lead one to believe. The RAM is highly controlled and the storage can be directly ascertained. There is a decisive method that RAM utilizes to make its memory available to certain areas of the computer system.
Forms for RAM
RAM is what is known as discrete microchips which means that it is separate. An additional form of RAM is modules which attach into outlets in the motherboard of the computer. A network of electrical pathways to the processor allows the connection to spark for the RAM.
Why is RAM Important
RAM serves the very important function of retrieving information that must be accessed in a quick manner. This operation is very similar to the human brain's function in retrieving necessary facts from short term memory. Open files and the utilization of applications on a computer systems requires the assistance of RAM. Users that play alot of video games with detailed graphics or keep alot of folders open while on their computer, will need the use of additional RAM. This will allow them to better access the information they need when the time comes. RAM is held onto a limited time, but it allows the information to come up quickly and without much fuss on the part of the computer user.
Where Is Ram Located
Anyone who works as their own tech geek on their computer system may be highly concerned about what is ram? It is a very important piece of a computer system. It is Random Access Memory which is the location where the application programs, the operating system, and data presently in use are stored. This way the computer's processor has the ability to reach them momentarily when needed. RAM is head and shoulders above the other various types of storage inside a computer system. It's even faster than floppy disk, hard disk, or CD-ROM. The information stored in RAM is only accessible for the length of time that a computer is begin run. Information previously stored in RAM disappears when a computer is shut down. When the computer is turned back on, information from hard disk is retrieved to bring RAM back to the forefront again. RAM is much like main memory that is accessible by programs.
How Does it Work?
RAM operates much like a human being's short-term memory. Much like the human brain RAM is able to draw upon the computer's long term memory for information. This is often necessary when short term memory becomes full. Most computers come equipped with at least 256 million RAM bytes plus the hard disk which has the capability of holding 40 billion bytes. Data is placed on a magnetized area that resembles a record. Computer printers also hold bytes of RAM as well. Each byte of RAM has the ability to be ascertained separately without the other bytes being accessed.
Types of RAM
RAM comes in dual forms. DRAM which is Dynamic Random Access Memory and SRAM which is Static Random Access Memory. DRAM is the most typical of the two types. DRAM requires refreshing at a rate reaching in the thousands each second. DRAM's times for accessing information are 60 nanoseconds. SRAM is more costly, but does operate at a much quicker pace than DRAM. The interlocking of a capacitor and a transistor produces a memory cell. This is one bit of data. Also, SRAM allows access at times as quick as 10 nanoseconds.
