Memory

:: DDR/DDR2

DDR2 is one of the newest types of memory modules available for consumer use. Unlike its predecessor DDR, DDR2 has the connector pins under the chips instead of around the chips. DDR2 speeds pick up where DDR left off at DDR-400 (400 = Data transfers per second) up to DDR2-1066.

:: DIMM

DIMM (Dual In-Line Memory Module) was the next upgrade from SIMM. Because DIMM is Dual only one memory stick is needed in order to us a computer, unlike SIMM which needs to be installed in pairs.

More Information

:: Flash or Thumb Drives

USB Flash drives are great. They can hold lots of data, are small and light weight, and best of all USB drives are hot-swappable. USB drives also have no moving parts so therefore are less common to break down. We recommend purchasing at least a 256MB USB drive. This will provide plenty of room for documents, music, and photos.

:: GB or Gigabyte

1GB (Gigabyte) is 109 bytes or is big enough to hold approximately 3000 pictures or 220 songs (MP3). Most storage devices for Mp3 players have 1-40GB, and Desktop Computers 40-250GB.

More Information

:: Hot-Swappable

Hot Swappable was commercially introduced with the advent of USB devices in 1995. Hot-Swappable is a feature that allows a user to take a compatible device which is usually USB and connect or disconnect the device without restarting the computer. Please be advised that USB Flash drives must be removed correctly by clicking disconnect-connect, other wise if the computer is writing or reading from the flash drive all data may be lost.

:: Laptop Memory

Laptop memory is smaller in size, making it incompatible with desktop systems. The same memory technologies that are available for desktop systems are available for laptop systems.

:: MB or Megabyte

1MB is what a floppy drive just about holds or approximately 40 documents, or half of an Mp3 song. 1MB is the building blocks for 1GB.

:: Memory/Ram

Memory or Ram (Random Access Memory) is what laptop computers, phones, desktop systems, and PDA’s, use to operate. Memory allows devices to temporally store data in a high speed environment before the processor (CPU) needs it. Memory in most devices is upgradeable, but may come in different forms, for example SD-Card, Memory Chips, Compact Flash, Micro Drive, etc.

:: RIMM

RIMM (Rambus Inline Memory Module) has 184 pins while a DIMM may have 160 Pins. The pin differences are not interchangeable with DIMM and SDRAM. RIMMs have a metal cover on both sides of the memory stick to dissipate heat. RIMM memory must be installed in pairs just like SIMMs.

:: SIMM

SIMM (Single In-line Memory Module) is another type of older memory module that must be installed in pairs. These days this type of memory is not used very often, mainly in older technologies such as older computers and printers.

:: TB or Terabyte

1TB or 1000 Giga-Bytes. 1 TB can hold up to 284,000 digital photos, or 250,000 songs (MP3). Desktop computers are increasingly coming out with Terabyte storage options as price per byte continues to drop. Unless a huge amount of storage is required for music or videos we don’t think the average person will need this much space. A good 80GB to 120GB hard drive is plenty. This of course depends on what the user uses their computer for.
