Likely you want to enable WiFi access on your desktop or laptop without wireless adapter to eliminate the need for so many cords. Well it is good your here to learn the difference.

PCI WiFi Adapter

I’d like to start this one off by saying if your getting a wireless adapter for your laptop stop reading and just buy a USB dongle you can’t add PCI devices to a laptop.

If your wanting to add wireless to a desktop though that is a different story. PCI devices are much faster than USB devices, and can achieve much greater speeds, and allow for more stable connections. Their raw power, and ability to transfer data is much higher than a USB dongle.

While I say PCI don’t worry if all you have are PCI-E slots most if not all WiFi adapters have this port option available.

Usually these kind of adapters are best if you do a lot of bandwidth intensive task, and game a lot. Their price is not bad either considering they range from $10~$100 dollars. The more you pay the better off you are though. At $10 your probably looking at B/G wireless adapters which will max out at 54mbps which for more people is good enough, and perfectly fine for gaming or YouTube. If you need more though be ready to pay more.

Doing a quick Amazon search you can see the prices aren’t bad. PCI devices are really easy to install too. All you got to do is open the side of your computer see which slot it fits, and than identify that slot if it exist on your motherboard. These days they are usually marked on the board as well in white text. You can also look online using Google image search.

USB WiFi Adapter (Dongle)

Depending on who you go with, and what speeds your looking for these range from just a few bucks to $40+ according to Amazon. The main thing with USB Wifi Adapters is that they are convenient, pretty fast, and very portable. If your laptop’s WiFi adapter burns out a cheap USB Wifi Adapter is the best option rather than getting it repaired.

USB Adapters are great for space too. Usually people who are working on small projects with Raspberry Pi devices use these to give their devices WiFi capability.

The downside to USB WiFi adapters are signal range, and the fact they usually max out at 300mbps on the market. Anything above 300mbps starts to get expensive.

Conclusion

If your looking for convenience, or need a laptop WiFi replacement than get a USB WiFi adapter. If your using a desktop than I would recommend a PCI or PCI-E WiFi adapter card which are relativity cheap, and easy to install.

Wireless B vs G vs N vs AC | What’s the major difference

Wireless B vs G vs N vs AC | What’s the major difference?

linksys-g-wireless
From the stone age, but still running strong this is a wireless router that can do both wireless B, and G modes.

Wireless standards keep evolving, and with each major evolution they get faster. So today we will look at the wireless standard itself, and review the differences in the difference modes and their speeds.

WLAN Standard 802.11

ieee-wireless

The Institute of Electrical and Electronics Engineers (IEEE) is an organized group of engineers. They created the standard for WiFi technology which all wireless routers will follow. They called this standard 802.11. All routers at the time were built around this standard. There was no letter designation, such as “G”, “N” or “AC”. This 802.11 standard was released in 1997.

The main problem with this standard was that it was way too slow. Today’s routers are made to this standard and thus the letter designations come into play.

802.11 Enhancements

Lets explain a few things first. We will be starting off by talking about Wireless B, but something did come before B and that was the A standard. A was released about the same time as B, but B was cheaper thus being more popular. A devices were mainly used by businesses so you don’t really hear about it when looking for routers online (and you won’t). Wikipedia has some great information on the history of wireless standards.

802.11B – Wireless B

Routers that came with just Wireless B are not longer made though a bunch of routers still support Wireless B so you should know a little bit about it. Wireless B can support a maximum throughput rate of 11mbps. You can also use the signal with no interference up to 150 feet away. Wireless B operates on an unregulated 2.4GHz range which is bad because many home appliances operate on this frequency.

This means that home phones, and things like microwaves can actually cause interference if your router is somewhat close to these devices however if it is not too close you should be good.

It is also good to note that Wireless B can actually be regulated on Wireless G routers that allows channel selection, and supported Wireless B.

802.11G – Wireless G

The G standard was a big push forward, and supports up to 54mbps. Wireless G just like Wireless B initially was unregulated until manufacturers like Cisco’s Linksys routers started adding channel selection support thus allowing you to switch channels and reduce interference.

Wireless G is backwards compatible with Wireless B so many routers support accepting both signals at the same time. Though I am about 100% positive that none of you reading this actually have a device that only supports Wireless B, but more likely devices that run on G or N. G’s main benefit is that it is faster than Wireless B.

802.11N – Wireless N

Wireless N supports a max speed of up to 300mbps with two antennas. With an additional antenna it can reach speeds up to 450mbps, Normally though you can expect to see speeds around 130mbps or so.

Wireless N operates on 2.4GHz and 5.0GHz bands at the same time. N devices can operate on multiple signals. It is called MIMO (Multiple-IN – Multiple-OUT). That combined with the two to three antennas, increased signal power, and rage it is clear Wireless N is a standard you want to use for very high speed devices.

 802.11AC

This is the next big thing as of the writing of this post. Wireless AC is out, and on the market offering speeds up to 1733mbps which is an enormous increase from Wireless N. It is also know as “5G Wi-Fi”. The standard was introduced in 2012, which is now the current standard that can be found on many newer routers. AC Routers also support Wireless N which makes them fully backwards compatible with G.

I hope this post was very informative, and helps you make a decision on what type of router you want to buy. Honestly anything from G and above suites the needs of most people unless you, and your whole family are all doing some very bandwidth intensive tasks.

If your interested in buying a new router consider an AC router. Here is a link below to an Amazon search result for AC routers.

RGB vs CMYK

RGB vs CMYK

If your unsure of which to use than your in the right place.

RGB vs CMYK

RGB – Red, Green, Blue

RGB is an additive coloring method. These three colors can form any color in existence, but the problem is that ink cartridges do not come in RGB.

RBG is the color scheme that is associated with electronic displays such as CRT, and LCD monitors, digital cameras, and scanners.

RGB is an additive type of color scheme. It combines all three primary colors together (red, green, and blue) in various degrees to create a variety of different colors. For example white is when all three colors are combined together. When they are applied together at the lowest degree possible you get black.

Many photo editing software’s use RGB because it offers the widest range of colors to choose from. This is why you never see CMYK used in digital applications that are not designed to ever touch paper.

Pro tip: Photoshop (Raster Graphics) – Defaults to RGB

Pro tip: To avoid any discoloration when printing something make sure to convert the color mode of your image to CMYK before printing. If it is for something simple though usually the computer can handle the conversion and print what you see on screen just fine.

CMYK – Cyan, Magneta, Yellow, Black

CMYK is a subtractive coloring method. Printers print in CMYK mode even if the image your printing is in RGB. CMYK is a four color mode that uses the colors of cyan, magneta, yellow, and black together in all different degrees to create the desired colors.

It is a subtractive process, which means that each additional unique color means more light is removed, or absorbed, to create colors.

When the first three colors are added together you do not get black, but actually a very dark brown. The fourth color black is used to completely remove light from the printed picture so you perceive that area as black.

Pro tip: Adobe Illustrator (Vector Graphics) – Defaults to CMYK

TIFF or TARGA?

TIFF or TARGA?

Well we’ll give it to you straight.

It depends.

Short sweet and to the point go with TIFF. TIFF is now owned by Adobe so you get the best of both worlds the ability to be fully compatible with Photoshop, but use other programs like Gimp.


If you suddenly feel like you need to Convert all your textures now don’t worry theirs an app for that. XnView your welcome.


I’ve noticed Cinema4D works best with TIFF’s. Also note that when saving to TIFF format the extension is generally .tif

TARGA is powerful as well, and these days it comes more down to preference. I prefer TIFF for two reason. One it works very well with Cinema4D’s BodyPaint3D, and second it’s backed by Adobe so I’m not screwing myself over for the future. Below are two Wiki links for each of the two formats so you can read up more on them in detail.
