In one of the forums today someone was asking the question do I buy 4GB of fast memory or 8GB of slower memory.
Generally more memory is better but it does depend on a number of factors. If you are on a 32bit OS then the limit of 4GB is how much it can address so putting 8GB is a pointless exercise.
If it is a very memory intensive application and you can get the data into memory then faster memory is going to give you a better result.
You also need to know that DDR3 memory which is what is coming out in new workstations is not compatible with DDR2 which is in older motherboards.
So Anywho do check to see if your motherboard will support the DDR that you are going to buy

Going through a thread today I came across someone with a 2Mb connection that was querying if they are getting the 2Mb they pay for.
Running a speed test showed that it was not and this is normal. The speed test is just sending a few bytes of information and seeing how fast it gets a response.
What yo are paying for is really through put and if you want to know if you are getting what you pay for you need to put a lot of data through the system.
So if you are downloading a large file you may get it to reach the 2MB. Download several large files and you are more likely to hit the 2MB.
You also have to remember that we think that we are the only person accessing a file on a server somewhere when the reality is very different with many thousands of users accessing files. Each request is handled in its own time and you have to wait your turn in the queue.
It is like standing in an empty stadium and using a cellphone it is very likely it will work fine. If you are standing there with 50000 fans using their cellphones then you may find firstly that you cannot connect or that the quality of the call is not as good as it could be.
I picked up on a conversation where someone was looking to start an Internet Cafe. I thought that this was pretty much a business like a video rental - not going to be around for much longer.
The writer though, despite the protestations of other members on the forum, was adamant that it would work.
It is apparently in a rural area with a high traffic of people who are relatively wealthy.
If he has done his research and he is right then what would he need?
The suggestions came in thick and fast. Reliable PC\'s not too high spec and if you can get 2nd hand equipment. Software to control the access you can\'t rely on the person at the cafe to do it for you.
Ancilliary services such as photocopying and Lotto can increase the feet through the doors.
Good advertising and the location are also important. You don\'t want to be on the 3rd floor of a building.
If it is in a rural location then you may need to find a wireless solution for the connectivity.
All good advice but at the back of my mind I am not convinced that this business is going to be around for long at least not as an Internet Cafe.
Thank you GBS (George Bernard Shaw)for the comment.
A lot of people in the forums seem to be complaining about being capped between certain times or that their downloads are not as fast as the line and ISP they are paying for.
The ADSL is a best possible service. ie if you have a 384 line then that is the best that you will get as a download speed but it may be a little worse or a lot worse than that. Broadband is not going to provide a guaranteed service.
So while we all want to have the best possible service I believe that it needs to be looked at over a longer period not that it was bad between 5pm and 11pm when I was only getting 100Kbs for example when I get 200-300Bps the rest of the time.
If you like the road sign says 60km and hour but the traffic volume reduces it and you only move at 30km. So that is what you get at 7am down the busy road into town. It is not the 60km that you can do at 3am in the morning but you have to live with it.
So in short average it out and one statistical snapshot is just that a snapshot
Frequently people are asking about tools to monitor bandwidth even down to individual PCs on the network. In the last week I have seen 3 threads alone that relate to this.
SO below are a few tools that might assist. If you have others let me know and I will add them Cucusoft Netguard [url=http://www.cucusoft.com/netguard.aspx]here[/url] will monitor each application on your PC and its bandwidth usage. Some reports though that is not monitoring Google Chrome.
Provides much the same but reports indicate that it is easier to use.
Networx [url=http://www.softperfect.com/products/networx/]here[/url] Is another option that you can look at
Bitmeter [url=http://codebox.org.uk/pages/bitmeter2]here[/url] looks good as well especially as it has a web interface that you could use to access the info remotely.
All of the above are for individual workstations to monitor traffic over an office network you need to do work with routers and other monitoring tools.
I came across this one [url=http://oss.oetiker.ch/mrtg/]here[/url]which does need a SNMP capable router.
Conference phones over normal telecommunication lines have been around for ages. Polycom is probably the market leader here.
Someone asked about using a polycom device over skype?
Personally I wouldn\'t Skype does not have the best sound quality and having a great conference phone is not going to improve it.
I would rather use a PC with speakers and an external microphone over skype. Done it often and it has worked well.
Nothing is more difficult as a human than to try and see trends when you are just given a set of figures.
Graphs though are something that immediately we are able to see trends and anomalies.
More people are putting graphs on their web pages and with some applications in Cloud environments there is a need for embedding graph code in the applications themselves.
I did a bit of research though and if I had to do graphs in my web application I would look a bit more into the following :
[url=http://www.fusionsoftware.com]Fusion Software[/url] has a great looking product. I looked at some of the chart types that it supports and the range and usage is extensive. Purchase is either suite or the appropriate components. They also have extensions into products like Dreamweaver to make the integration easier.
[url=http://www.jpowered.com]Jpowered[/url]has Java and PHP solutions. They also have tutorials on embedding graphs into web pages and other interesting articles on graphs and their use.
You could also look at what Google is [url=https://developers.google.com/chart/]doing[/url]
The pricing I will leave you to look at but if you want it to get people coming back then you may have to pay for the best
Setting up a wireless network is easy to do today and is something the professional does in his sleep.
For the amateur just a word of caution.
Creating a wireless network opens up your LAN (and hence access to your PC) to anyone who can get into the wireless router. If your router is connected to the internet then they now have access to use up your bandwidth as and when they like.
SO very important to put a password on your wireless connection. By default the router does not have one generally so it is important that yo put the security in place as soon as possible.
I would also treat it like any other password and change it regularly in case someone has managed to get access.
Another good tip is not to cycle round the passwords either.
So go for wireless but be careful.
The first time we connect the modem or router to our broadband we tend to do so with a blind plug and play attitude.
If therre are a number of people using the connectivity say in a small office or a home then the demands that each is placing on the connectivity is different. Someone could be streaming video from Youtube, other just surfing the web whilst other may be using voip.
Unfortunately each of these has different demands to ensure quality of service and if we do not put priorities on the data according to its type then not everyone is going to be happy.
This is what QoS in the modem/router is meant to do.
It is not an area that is immediately obvious to the first time user. Some modems make it easy to do but others assume that you have the knowledge and know what you are doing.
I came across this series of videos and reading material that will give you a better idea. Follow this [url=http://actionpacked.com/3-easy-steps-understanding-qos]link[/url] to start your appreciation of what you could do with your router.

I was responding to a forum post earlier and in doing so I thought the option to take was obvious.
The person had gone away on business and when he came back his Telkom supplied router had stopped working and he could not get to the internet.
He had the technician come out and he confirmed the line is working. The person now wanted to know what to do. He had had the router he thought for more than 2 years.
I had a similar problem a few years ago. I took the router to my local Telkom shop and explained the problem. I had been using the router for about 28 months. They tested it and agreed it was faulty and immediately provided me with a new router at no charge.
This is what I would do. It is one of those situations where you have nothing to lose and everything to gain. If Telkom says sorry it is broken you will need to buy another one then he has options available in the Telkom store. They may even just provide him with another one at no cost. So my advice if you have an ISP supplied product approach the ISP first and see what they can offer.
