FUTURE OPTICAL COMPUTER STORAGE-Holographic Memory.
Every year, we cannot fail to notice how computer systems increase greatly in speed, memory capacity and performance. A computer system bought today is, quite literally, out of date by tomorrow. As computers have become more advanced, the applications that they are used for have increased. Today, large files of sound and image data are frequently being stored. The need for greater data storage and faster data access is always increasing. Although conventional magnetic data storage is adapting well to these growing needs, it is reaching its fundamental limit. Improvements made to these conventional storage methods usually decreases access time. This is one of the reasons why a new technology using optical data storage is being developed. This new technology is called Holographic Memory.
Section 2 - What is Holographic Memory?.
Holographic memory is a promising new storage technology, which offers massive increases in speed and capacity. It also offers extremely fast parallel data transfer.
Another promising feature of holographic memory is that there are no moving parts, i.e. no magnetic platters, as used in conventional hard drives. This allows larger amounts of data to be accessed in shorter periods of time.
Holographic memory is a technology that uses a three dimensional medium to store data. This data can then be accessed a page at a time instead of sequentially.
Section3 - How does Holographic Memory work?.
Section 3.0 - How is a hologram created?.
A hologram is a block of photosensitive material, which records the interference pattern produced when two beams of light overlap. To record a hologram, two beams of laser light are needed because the light needs to be very pure and intense. Splitting a single beam of laser light into two creates the two beams. One of the beams is called the signal beam and the other is called the reference beam. The signal beam is made to reflect off an object and hit a photographic film.
Next, is the memory A.K.A RAM(Random Access Memory). ... Files represent programs and documents you can load into memory. ... Floppy disks can hold approximately 1.4 megabytes of memory. ... These devices have high capacity, removable media, optical drives. Unlike the hardrive and floppy drive using magnetic storage, these use optical(light) storage. ...
The configuration you chose should depend - to some extent - on the amount of expansion, (if any) you may want to plan for in the future. ... Random Access Memory (RAM), is system memory, or AAon board memory@@. ... CD-ROM (Compact Disc - Read Only Memory) drives are optical disks that are physically the same as an audio CD, but contain computer data. ... A DVD (Digital Video Disc) drive is an optical, high capacity version of the CD-ROM. ... Finally, ask if they would buy another computer system from that company in the future. ...
Another crucial element needed is the memory having 256MB is a sufficient amount of room to store data. ... These elements are the most crucial parts of a computer; however, you can choose to customize your PC by adding gadgets such as a DVD player, burners, wireless keyboards, wireless and optical mousse, monitors, LCD flat panels within others. ... It has a memory of 128MB, and a 40GB hard drive. ... The hardware memory includes 128MB of storage and a hard drive that holds 40GB. ... Finally, we have the IBM Think Centre A30 8191 Pentium 4 with memory that can hold 256 MB and a hard drive t...
One of the reasons for the success of computer animation is the progression in computer technology and software. Computer animation can date back to as early as the 1962 when Steve Russell, Shag Graetz, and Alan Kotok created Space War, the first interactive computer game. ... In 1995 the 3D-computer animation age was born when the release of Toy Story introduced the public to full-length computer animated movie. ... The solutions for this problem is using a program called Optical motion capture. ... OMC (optical motion capture) can be used in three simple steps. ...
When we mention the word "technology" one will instantly think about computers and computer science. ... Memory is extremely useful as things can buffer into the memory instead of streaming off of the hard drives. ... The only real difference is ball versus getting an optical mouse. An optical mouse uses a laser and reads on the screen accordingly. ... Any type of optical mouse should be good for bossiness use. ...
The now-preferred device for pointing and clicking is the optical mouse. This Microsoft Intellimouse uses optical technology. ... Although LED-based optical mice are fairly recent, another type of optical mouse has been around for over a decade. ... The most commonly used computer output devices are: 1) Raster-scan cathode ray tube (CRT). 2) Memory-tube displays. 3) Plasma Displays. 4) Liquid crystal displays ( LCDs). 5) Plotters. 6) Printers. ... Raster scan systems uses a memory buffer called frame buffer (or refresh buffer) in which the intensities of the pixels are stored....
Many computer manufacturers and computer users are expressing their thoughts about this issue. ... Digital photo cameras have memory cards in the size of a biscuit. ... Either optical discs or flashcards are used. ... Flashcards and optical discs are preferred. ... With USB memory sticks on the market, CBC predicts that those "keychain-sized USB drives will cost the same as floppy drives" in the near future. ...
Memory management is a key subject under disciplines of computer science, software engineering and information technology. It is a function of the operating system that is concerned with managing the primary memory of a computer system. With memory management the computer manages every memory allocation to each and every process in the computer system and also manages freeing up of this memory that is allocated. ... It will update itself of all changes in the computer memory in relation to tasks or processes. The protections provided by memory management to the host computer are two; a base re...
