Tips

 

GENERAL TECHNOLOGY FACTS

 
  1. The first computer company was the Electronic Controls Company and was founded in 1949 by J. Presper Eckert and John Mauchly, the same individuals who helped create the ENIAC computerr.
  2. The first email was send over the Internet in 1972. 160 billion emails are sent daily, 97% of which is spam.
  3. A twillionaire is a twitterer with a million or more followers.
  4. The IBM 5100 is the first portable computer, which was released on September 1975.
  5. One Gigabyte is approximately equal to 1000,000,000 bytes .
  6. Intel introduced the first microprocessor, the Intel 4004 on November 15, 1971.
  7. symbolics dot com was the first ever domain name registered online
  8. A NeXT computer used by Tim Berners-Lee was the world’s first web server
  9. All three letter word combinations from aaa.com to zzz.com are already registered as domain names.
  10. The first ever ISP was CompuServe which still exists under AOL, Timer Warner
 

USB FLASH DRIVES

 
  1. Capacity isn’t the only thing to look for when deciding on your USB drive purchase – its performance is just as important. Look at the data transfer rates when determining your next flash drive purchase; the higher, the better!
  2. Despite having the word “Drive” in its name, a USB drive has no actual moving parts. It is dubbed as such due to its using the same system commands to read and write data as a traditional mechanical disc drive.
  3. You can load up your flash drives with Portable Applications. Access your favorite software everywhere, without having to install them on the host computer. These include Firefox, Java and many more. Even some games are available, for hours of easy entertainment.
  4. A bootable operating system can be created using a USB flash drive too! This means that in the event your system crashes, you can have a working version of your operating system up and running in no time. This is particularly useful for netbooks or laptops, as they may not come with a CD/DVD drive.
 

FLASH CARDS

 
  1. Flash cards are also known as "bridge media" items, which let you pass data between different devices without the use of a PC. 
  2. Flash cards are able to play music, videos and more, without a drive mechanism like those found in CD and DVD players. 
  3. When it comes to transferring data, flash cards are a lot faster than regular old CDs.
  4. TransFlash cards and microSD cards are essentially the same.
  5. Switch off your camera before removing the memory card from it.
 

MEMORY MODULES

 
  1. When it comes to PC memory devices, JEDEC sets the basic specifications to which all RAM must adhere. 
  2. CAS latency is one of the most important parameters of a memory chip, as it is the time it takes to get data to the data pins. Immediately after the CAS Latency, the data is available on the memory data pins.
  3. ECC stands for error-correcting code. An ECC module has an additional memory chip per memory bank, which is responsible for detecting and correcting 1-bit data errors as data passes through the memory module.
  4. The typical counterfeit case involves blank or UTT chips being marked and illegally passed off as major brand chips. They are sold at a higher price, and because the quality is not as good as major brand modules, the reputation of the real major brand companies suffers. Counterfeit chips make up approximately 10% of the total market.
  5. MAJOR BRAND IC (tier-one): The current leaders in chip production are Samsung, Micron, Hynix and Elpida. These companies are known to maintain high standards for their ICs. Their chips are also consistently available in the market, setting them apart from other major brands. 
  6. UTT (UnTesTed) CHIPS and ETT (Effectively TesTed) Chips: Because testing standards have been lowered, the cost of UTT is lower than other major brands. But performance, quality and cost will vary from company to company. Often, UTT chips are remarked and passed on as new specification chips. 
SSD
 
  1. SSDs help reduce energy costs and support the green data center.As SSDs do not feature any moving parts, they use less energy than hard disk drives (HDDs), producing less heat and thus requiring less cooling. 
  2. When it comes to price/IOPS, SSDs is the optimal choice. With no moving parts, the latency of SSDs is very small. In an environment with random access to large data packages, SSDs perform extremely well, delivering amazing read throughput. 
  3. For SSDs, form factor isn’t as important.
  4. Today’s flash chips are built into disk frames, so that they can support the same form factor as hard disks used in current server or RAID array designs. Like HDDs, they are available in either a 2.5” or 3.5” form factor. Unlike HDDs, where these form factors have an immediate effect on price and available capacity, this is not as important for SSDs. 
  5. The small flash chips used in SSDs allow for higher-density storage systems. 
  6. While SSDs are typically built into a disk frame today, this need not be so for future storage devices. And since flash chips use little energy, they don’t get as hot and thus do not require as much cooling as HDDs. 
  7. The choice between SSDs and other storage media is usage-dependent.
  8. The ideal infrastructure depends largely on the specific scenario. If fast reads and high speeds are the priority, you’ll want to go with SSDs instead.
