Chech this out

Hallo viewers!
Today Mr Van Stam, the director of linknet in macha came with a visitor overseas to look at the mighty projects being done in macha.They came in class and observed what we were doing and told us about the meeting he had with the minister of Education in lusaka.The meeting was fruitful and they will soon be coming to macha and hoping that they take a part in this investment for the rural people and the upcoming Ubuntu Campus.
Today i should say i'm impressed on the technology i'v seen in macha, the wireless internet, the networking,the hospital,MIAM and in general the plan and the design of the community,Its beautiful. People should see this.It may be in the rural area but the activities being done by everyone is great.Everyone works together all are friendly and above all everyone looks up to God to make things work.Visit this place and you'll see the beauty.A few years from now,Macha will be everyones place to visit and invest.
Mr Gertjan Van Stam,the Director of linknet has been in Zambia since 2004 and from what i'v seen around this place he is a man with a vision,helping to develop the local peoples skills and free training.The locals are 6 so far and they are doing A+ which constitutes of basic software,hardware,networking etc.
They are been taught by Mr Jonathan Backens,a young man from united states,He did Combined courses in Engineering and Computer science as majors and some other stuff.A Good teacher indeed. The local students can actally build computers, can determine sources of failure for several problems in troubleshooting or looses of signal , helping users,can set up a network just a few to mention..And i should say that is great.They havn't been to college but they are being taught by someone that has been to university and they are good.Like yesturday, we were putting up internet cables and connecting them to our PC's,(RJ 45 cables) and testing if they were working,and they did!
I believe that if people are talented they should extend a hand to others like what Mr vanstam and Mr jonathan are doing.
Jumping to class now,
Today we were learning about security, How information is transfered from one computer to another via internet.
Data is bundled together as packets and for it to be transfered to another computer through the internet, headers are attached to it.
The first header tells us what program is used to read the file.It is usually FTP, and it is attached to both ends of the data.The second headers surrounds the first ones and are called TCP which tells us where the data is coming from and where it is going, it will give you the IP Addresses and finally the data with the headers is sent to the required destination.Upon arrival to the desired computer the pieces are put back together and the headers fall out the outer ones first and the inner ones second.One at a time. The inner headers will again tell us which program should be used to open the files. Finally the receiver gets their lets say song and open it through windows media player for instance.
One would wonder how your internet service provider knows that you are connected to the internet.The two main ways are:
1. Through Point to point connection ( PPP).A number is dialed to your ISP to be connected and their is need for a password.
2. Through DSL. A single telephone line goes through a DSL box and two other
connections extends from the box.One goes to your PC and the other to your
phone. This is advantageous. You can have a single connection to serve to
two tasks in your house or work place.
On Security measures we discussed various viruses and how they affect your computer,and certain ways to prevent down loading them.
Examples of common viruses includes:
1. Boot sector virus, this one moves the information in the boot sector
2. Stealth virus, it constantly changes
3. Root kit, This one loads before your operating system loads. It can change
the system and it cannot easily be found
4. Spyware ,Its a hidden software which reports on you to a website
5. Worm, It is self Replicating
6. Keylogger, records your typing and sends it to a the website
7. Browser hijacker, Everytime you open a browser you go to their web page
Wow,just a few to mention.
How can you prevent them, the most important ones are that:
a) Do not open on links in the emails
b) Do not forward messages anyhow
c) Scan the attached document.

I hope you'll get one to two tips from what i got from class today
