distinct Types of Computer Memory

distinct Types of Computer Memory

Computer memory refers to either of two types of computer storage. volatile memory refers to Ram that needs to be constantly refreshed to be retained. Static memory is permanent warehouse that is retained even after the computer is turned off.

Ram or Random passage Memory is volatile memory that is erased when the power goes off. schedule instructions and data held in Ram can be accessed and saved much more fast than that held in permanent storage. Therefore, files needed to run a schedule and data that is being processed are held in Ram while they are in use. The amount of Ram you need depends at least partly on the operating system( a schedule that directs all the basic functions of a computer such as accepting commands from a keyboard, displaying input on a monitor screen, and controlling disk drives and some other peripheral devices) you opt as well as the type of programs you intend to run.

When you boot up the computer, in other words turn it on, the operating ideas or part of it is loaded into the Ram along with a range of utilities required for normal operation. Therefore, programs and data are loaded into what's left. As tiny as 2Mb(megabytes) total will suffice for most Dos( disk operating system-a proprietary schedule that controls all the basic functions of a computer) programs. In a Windows 3.x environment, 4Mb is the recommended minimum, but 8Mb runs far better.

Beyond operating ideas demands, the amount of Ram required depends on the applications to be run. For example, heavy graphics, real time video, and such need more Ram to keep things from slowing to a crawl or stop. Generally, off-the-rack machines come with 8 to 16Mb, more than enough for a normal purpose computer.

With improved handling of memory, reduced passage times, and lower cost have conspired to make larger amounts of Ram practical. Which in turn has given programmers free rein to add more bells and whistles. This also helps programmers to become more creative in writing programs that require more Ram. There is speculate to believe that this trend will continue.

As for static memory, you don't have to be very old to remember buying a computer without a hard drive, then later installing a 20Mb hard drive, unable to fantasize ever needing more warehouse than that. Today, a 250Mb hard drive is popular; however, most new computers are in the 500 to 1000Mb( 1 gigabyte) range. And you may need all of that Mb and then some.

Computer Memory fact #1: For the faint of heart, when programs or data files are called up from permanent storage, they are not moved, they are merely copied. If the power goes off during processing, programs commonly are safe. The only loss will be data that was changed since the last save.

Computer Memory fact #2: If you decided to get a Mac computer, don't worry. The Mac computer comes loaded with a proprietary operating ideas and the permissible amount of Ram to run it.
