What Is Memory Card Speed?

---

In a few short years since the launch of the first 4Mb flash memory card, the number of flash memory cards available for digital cameras and other devices has exploded with a number of different formats and speeds of memory card. It's no wonder the average person is totally baffled by this plethora of memory cards.

Not only are there different shapes (the format) and sizes such as Secure Digital (SD) Compact Flash, Memory Stick etc, but also different speed ratings.

Memory card speed is the card's performance with regard to how quickly data can be transferred to or from it. The card speed is often stated in 'Times' ratings i.e. 12X, 40X etc (just as the speed of recordable CD's and DVD's is measured), and sometimes more specifically in megabytes per second (Mb/s). By today's measure, sub 20X represents a standard speed, 20X to 40X is mid-high speed and over 40X is high speed. The chart below shows the relationship between the two figures.

8X = 1.2 Mb/sec
12X = 1.8 Mb/sec
20X = 3.0 Mb/sec
25X...

The Types Of Computer Memory

How can a computer be such an amazing gadget? To many people they just can’t be so amazed on how computers have changed the way we live. Computers can now be found in many sizes and shapes. Almost every home appliance seems to have their own mini computer located somewhere. From cars to buildings to almost every gadget there is, most of the time each one has a computer working to make them run and change the very way we live life.

First and foremost, the most important component of the computer is its processor. It is considered the heart of the computer that does all the calculating and processing. But with all that calculating and processing, the computer won’t be such a remarkable gadget if not for its amazing memory. Computer memory makes it possible to retain important information on a computer. Such data can be used again and again and retrieved when a certain stored data is needed. Without the computer memory, the processor will have no facility where to store its important calc...

Notebook Computer Memory - Upgrading Your Laptop

---

With the proliferation of laptop computers, choosing to upgrade or implement notebook computer memory is not as straight forward as it may seem at first.

There is a variety of different types of memory, and it is important that you choose memory that is compatible with your notebook computer. Memory is also a little delicate, so you need to be very careful when handling it.

Adding Computer Memory - Some Tips

You should ensure that the Notebook is turned of and disconnected from any exterior power supply. No lights should be visible, and if they are, stop and double check for any live power sources.

Notebook computers are a little different to desktop PC’s in that there is no need to take them apart in order to add memory. Access to the memory slots is via a panel located (usually) in the bottom of the laptop. Once you have found this panel, it should be a small matter of using a screwdriver to open up the panel and view the existing memory. In fact, you can do this to check the exact ty...

Isn't It About Time You Had A Memory Upgrade?

When was the last time your computer or the internet or life for that matter was working too good? Never right? My point is that we stop being successful in anything that we do if we sit back and let things come to us. There is no secret way to have success without working for it. The work is to always be improving. So what does this have to do with computers and memory upgrade?

Well for one thing life in general is getting more and more to be computer run. If you don't update your technology or do memory upgrade fast enough you can be in the "dark ages," before you notice. Even personal computers have large hard drives and very fast processor speeds, and it is making a huge difference in the productivity of people in this day and age. Whether you are a internet shopper, or a database guru, or a writer, or gamer, or researcher, the tools that you have with computers are essential to doing the amount of work that you are able to do.

So how do you improve your productivity? Well there are ...

Compact Flash Memory and Data Recovery

---

Flash memory gets its name due to its microchip arrangement in such a way, that its section of memory cells gets erased in a single action or "Flash".
Both NOR and NAND Flash memory were invented by Dr. Fujio Masuoka from Toshiba in 1984.The name 'Flash' was suggested because the erasure process of the memory contents reminds a flash of a camera, and it's name was coined to express how much faster it could be erased "in a flash". Dr. Masuoka presented the invention at the International Electron Devices Meeting (IEDM) held in San Jose, California in 1984 and Intel recognizes the potentiality of the invention and introduced the first commercial NOR type flash chip in 1988, with long erase and write times.

Flash memory is a form of non-volatile memory that can be electrically erased and rewrite, which means that it does not need power to maintain the data stored in the chip. In addition, flash memory offers fast read access times and better shock resistance than hard disks. These character...
