Hmmm, this question is big but small for a true system admin. Where do I start? Well lets start from the beginning. I will first list all the necessary components of a network:

1. ISP (At least 24MB for say 100 PC)
2. NIC (At least 10/100 Base 2T)
3. Well insulated noise free building (Not in front of a market and bus garage square)
4. Well ventilated and cool room for the servers
5. New PC's (At least those with Pentium 3 upwards with at least 800MHz)
6. Hard drive at least on each machine should be more than 20GB
7. Memory should be from 512Mb upwards
8. For crying out loud, have a network printer not a printer attached to a computer and shared. Get a printer with RJ45 port and plug it into a hub.

9. Hub, use intelligent hubs, remember that every message you send from one computer must be send to all the computers in the network first to see if the message is for them before making it way to the internet, if the message was not for the LAN.

Well you can use intelligent hub to cut down this route. Please don't use dynamic ip from the router or server, manually configure all the PC with there own IP, hence static.

As a good admin have at least one router for 10 PC's. SO if you have 40 PC's, you must have 4 router. It is good to cut down where message are send before going over the internet.

Use gateways to configure your network, just don't buy things and plug-n-play.

10. Come on, create a policy for your network, just don't allow people to download and install anything on your computer. Remember spyware, very dreadful.

Use window policy tool i.e mmc. Type mmc at command line and create your network policy and deploy it from the server or if you are not using server do it individually.

11. You see you need to know programming language to be good in IT, Write script language with batchscript (DOS) to delete any file installed when the computer is rebooted.

12. You must have a maintenance day like say every one month, before you open for business run new patches and antivirus on all the computer and also defrag the systems.

13. Remember old age, as soon as your computer start to make dreadful noise sell it to someone else and buy a newer one. Treat you business well and your business will treat you well. Don't think that the computers will serve you forever, nothing last forever, always remember that.

14. Don't run your cables very long, use short cable, remember recommended length is, for 10Base T 10 Mhz is 100 meters 328 feet. but that is including your running wire along with the patch cords at each end. you should not run your cable more than 295 feet, leaving adequate footage for any patch cords you may be using. even if your over the 328 foot mark, it will still support whatever your running, but it might be a little slow

I will assume that Java PDF API has not yet been officially added to JDK/SDK development toolkit. But I have read it in a forum that Sun is very busy testing and verifying all the submitted API's and those that pass validation and verification test would be added to the next version of Java development kit.

But there are so many Java API's for PDF, this is one of them, all you need to do is search google for Java PDF API

This is not a joke, Nigeria and other Africa countries are deeply into GSM, well that is good for them but you could do better.

If money is not the issue, roll out 3G networks, SIP, ADSL 24+, etc these are the latest technologies in telecom. Most of them are in beta, so don't promise your customers heaven and earth yet.

Set up small exchange servers at the most remote cities in Nigeria and approach the most powerful ISP/ Telecom that you can help them to reach customers at these location for just a small fee, that they shouldn't worry about infrastructure.

Ignorance can be a bliss, sometime it is worth trying out stuff first to know for yourself that the argument you are about to make will hold.

When you visit a site and hit the file save-as in your browser tool bar, it would save the .css and .js files even if their links where relatives.

Try it and come back here to argue with me further. Visit this site as a demo http://www.lsbu.ac.uk First go to View-source from your explorer tool bar and see that the .css and and .js are just a reference to another http site i.e

<link rel="stylesheet" href="/erclib/css/styleLSBU_css.css" media="screen" type="text/css" />
<link rel="stylesheet" href="/clearingGuide/css/clearingChanges_css.css" media="screen" type="text/css" />
<link rel="stylesheet" href="/erclib/css/v2_printstyles.css" media="print" type="text/css" />

Now, just navigate to http://www.lsbu.ac.uk and hit save-as from the file menu on your explorer and go to the directories where you saved it and see if the .css and .js files are not downloaded.

If they were, just don't argue blindly it makes your knowledge reprehensible .

Computers › Re: How Do I Convert Pdf Files To Word by sbucareer(f): 5:12am On Sep 03, 2006

yemo, you are mistaken. Java has pdf API, that can convert pdf streams to and fro any document type. Ask youself, how does pdf software converts any document to pdf?

Any thing that can be done can be undone in software. We have something we call reverse engineer, I am sure you have had of it. I will find the pdf API and post it later.

I do not work with Java again, I have changed job and now working on TCL/TK programming legacy interface to work with Topspeed middleware. So I have not done Java for a while. But promise to dig and find you Java PDF API

Don't say you cannot convert pdf to any document type particulary word document, because all pdf file are converted into pdf from some other document file

desiree, I know you are very smart girl that is why I will ask you to do this task for us. I know you have used the university or public library before. I appreciate that you know how the library works in terms of borrowing books and returning books and late fees and books on loan.

I would like you to write a simple formal specification using either z or formal method to depict the states of these events. I will start you off with the state.

1. borrow
2. return
3. onloan
4. overdue
5. onshelve

Write a formal specification for our young programmers to code. I know this will be easy for you, thanks.

Computers › Configure your Microsoft Outlook to read Gmail and other email providers by sbucareer(op): 10:59am On Sep 02, 2006

I thought I'd let people that don't know that, you do not always need to login to your email server to check your mails.

Outlook can do that for you, all you need to do is configure Microsoft Outlook to do that for you. If you are using outlook version 2003, you can work straight from your word document as outlook 2003 has word document incorporated into it with all the features like image, flash, marquee bold, underline, database, etc.

You can begin to send professional letter edited in word document, no more document attachments, just work straight from the email software, hence Outlook 2003.

As soon as you open Outlook 2003, it will login and download all your emails from all your emails servers. You can reply your emails from the Outlook 2003 and send it to the recipient without ever logging into your email server again.

You can choose to download and delete your emails from the email server or choose to leave it.

Here is a link for gmail on outlook 2003.

You can search the internet on how to configure your particular email server by searching the internet for reference. Here is how I searched and got gmail

Just replace gmail and add your email server, google will do the rest.

Computers › Re: How Do I Convert Pdf Files To Word by sbucareer(f): 2:09am On Sep 02, 2006

Or you can try my in house built software

The only snag is that it work with java, so you must have a JVM install on you box. At the moment it is a command line interface program. Here is how you run it.

This will compile the code for errors
c:/javac Main

This will run the bytecode
c:/java Main filename.pdf filename.doc

The two arguments are interchangeable, meaning that you can convert pdf to word and word to pdf. The file to convert must be in the same directory of the java class, the Main.

If all goes well, your new file will be created with the supplied filename. You MUST specify the file type by postfixing the the type i.e. .doc, .pdf, .xls etc.

Computers › Re: Please How Can I Create My Own File Transfer Protocol(ftp)? by sbucareer(f): 1:57am On Sep 02, 2006

I know Seun was kidding. You can never build an internet. Internet is referred to an electronic network of computers that includes nearly every university, government, and research facility in the world. Also included are many commercial sites. It started with four interconnected computers in 1969 and was known as ARPAnet. [url=http://www.google.com/search?ie=UTF-8&oe=UTF-8&sourceid=deskbar&q=define%3A+internet]1[/url]

But to the question, to built a ftp either a software or a server solution is needed. You would need:

For Software
You need to choose a programming language and design the software yourself or you can download a shareware ftp

Server Solution
You can host a web server on your machine, either apache, IIS, tomcat etc. configure the conf.xml to allow ftp and edit the location or directory where the ftp files would be stored.

1. Configure ftp in IIS
2. Configure ftp in apache
3. Configure ftp in tomcat

Once you have configured any one of your choice you can access you file by going to ftp://127.0.0.1/filename

Note
You must put or copy the file into the ftp directory folder to be able to access it. If you are working with domain name you can access you file with ftp://domainname/filename

If this will give you headache, just buy a domain plus hosting and make sure that the hosting company support ftp. You would need a software like the one above to transfer your file to their server.

But if you just leave you file in your computer and try to access it from another computer without proper and necessary internet and networking deployment, it will certainly not work

Computers › Re: What Area In IT Should I Go For? by sbucareer(f): 2:56am On Sep 01, 2006

Let me say the honest truth, IT/ITC is NOT meant for everyone. I feel very sad to say this to my brothers and sister especially those with fantastic educational background from other course discipline.

IT/ITC is an Engineering discipline. IT is now included in the department of Electrical and electronics and is one of the bodies of IEEE.

What all these means that Computer graduates are very highly disciplined student in their career like other students from other departments. I make this emphasis because everyone seem to think that they can learn IT anytime. It might not allways be the case now. Design a web site and running mysql to some backend system does not make you any correlated with IT/ITC.

IT/ITC is electronic engineering but not necessary electrical. Learning binary, switches, principle, paradigm and complex logic is what makes you different from a mere web designer.

Believe me, any IT/ITC graduates MUST learn one type of language and must understand the theory and implementation of information system and who is the information system made to server in an organization?

You should really look at the job market for IT/ITC and requirements for joining a firm. The junior positions, you should look at the amount of technologies they expect you to know already.

DBA, you MUST like programming language to embark on this and must understand the Dr Boyce and Ted Codd normal forms. You must understand the flow of information system within any organization, hence someone with a degree in information system management will do better than you, no doubt.

Web design, it NOT an engineering prerequisite, but it is used to teach enterprise application development. Designing a web site can never make you rich, thus it is subject to argument. But enterprise application development using HTML would undoubtedly make you rich. Please know the difference.

Programming, is the core unit in any electronics course, both BEng and BSc, which are part of the Engineering department, under the IEEE.

Learning programming alone would fetch you money but learning the principles of programming would make you rich.

In Software Engineering we use model-based notation to validate and verify a specification. They employ the use of Maths and predicated. These are translated into what we call information specification.

If you want to build a car, the customer would only tell you that they want:

1. A car that would do 180mph and take a corner at 40 degrees
2. That uses 100mph per 20litres of fuel
3. etc

These are specifications. You need to translate it into a car. This is how software works. IT students at work place uses lots of methods to translate requirement specification:

1. [url=http://staff.washington.edu/~jon/z-book/what-is-z.html]Z[/url] notation is one
2. formal methods is another one

There are three types of formal methods

1. Event approach
2. Function approach
3. State approach

The premise for all this, is that IT students are better equipped with information system and it paradigm to just a brilliant student from other department trying to become an IT expert.

The most obvious case it likely that the student will fail in their endeavors to becoming an IT expert. Because the educated IT ones will always outsmart them and there are lots of them about.

To anyone reading this and planning to start university, be careful the course you choose to study as it will have a very big impact in you life at a later stage.

To all my IT/ITC and BIT and BEng, well done and dominate the IT sector because that is what you studied for.

As soon as you start getting the idea, you'd seen straight away that programming is very interesting and rewording.

The first task to do when you have learn and understand some useful controls. Design a GUI and task the application to render a question based on the radio button selected i.e

You can use football as it would involve importing image. Ask a question like select any radio button to reveal the player.

Programming › Re: Where Can One Learn Vb.net Cheap And Fast In Lagos by sbucareer(f): 1:46am On Sep 01, 2006

Learn all the objects in VB, that should be your first priority. Get a piece of paper, probably should be your logbook.

Write down all the objects (components) and there usage. In .Net it is called the control. In Java it is called API.

A typical example would be Label. Label is an object that encapsulate other important elements like:

Text
Location
Size

These are just few elements that a Label object encapsulate. Do your learning by providing the remaining elements of Label and other components or controls. Also, write down their usage and make sure all these goes into your logbook.

Example of Logbook

Learning VB 2006

Date : today's date
location : where you are today
Purpose: learning controls (Or any other thing)

Objective:
Controls are blaah blaah baa,
Define a control i.e Label

Elements of Label
1. text
2. Location
3. Size
4. etc

Usage

Dim screen As New Label()

screen.text = "Nairaland thank you very much for teaching me VB"
screen.location = New Point(135, 67)
screen.size = New Size(36, 20)

These are just few usage of Labels. There are probably thousands of objects/controls in VB, in Java we have almost 3 million. As good as you think I am in Java, I only know about say 100 objects/control and how to use them without referring to books.

I refer to book when I am doing something new and after that the object stays in my memory.

Like you have been adviced earlier, you need to keep learning no teacher can teach you better than yourself. Get a computer, very important and install Vb .NET

It is like learning to drive a car without owning one. You get someone to use their car, after the lesson your are left wondering in your head at home how I could have made a brilliant manoeuvre. But if you'd your car, you could have tried it straight away.

Programming › Re: How Can We Impliment Voice Recogination Software. by sbucareer(f): 3:21pm On Aug 22, 2006

If you meant implementing voice recognition software or devices that controlls some useful smart house functions like smart homes device.

You would rarely need a computer. Most of the voice singal are processed via a mobile phone and many other wireless intelligent device. Mind you, in Nigeria this application would be useless i.e. (No Static Power). If the energy company decided to take electric for two days, you would not be able to gain entrance into your own house.

Security breaches are another aspect of this technology. Although mobile devices and wireless applications has seen less virus compare to their Internet friend. If your wireless device has been compromise, someone could gain access to your home.

But in the western world like the America and the UK, we have seen steady increase to the usage of wireless controlled smart home, particularly by the rich and famous.

Not that the rich and famous are the only ones that could afford it, but the fact that they live in big mansion and apartment that is disperse from their neighbors make it a very good gadget for them.

When you live in project and council flats sharing corridors with other tenants and central door entry, it is hardly a smart thing to do as you would be open to people trying to fiddle with your system especially your neighbors.

It is good when you live in a mansion and you have a personal entrance gate to your house, that could be fitted with electronic emitting device from your mobile phone. As soon as your mobile phone is in range it will transmit an opening signal to the gate and you can chose to accept or reject the command. The same applies to other things in the house you want to controll remotely.

Computers › Re: How Should I Set Up My Home Network by sbucareer(f): 12:52pm On Aug 20, 2006

Why USB? USB is NEVER a good network peripheral. Some would say USB is not a network component.

Hardware, standard Universal Serial Bus. An external peripheral interface standard for communication between a computer and external peripherals over a cable using bi-serial transmission.[url=http://www.google.com/search?ie=UTF-8&oe=UTF-8&sourceid=deskbar&q=define%3A+USB]1[/url]

It replaces the old Serial and parallel ports on a PC because of their shortcomings. Because of converting data from serial to parallel, and error code bit correction and data degradation, USB was invented. Not only it is portable, it allow must faster data transfer with less errors.

But USB never made it into networking device components. Most serious network device still use serial and parallel port i.e. Switch, routers and the ,most popular network device, CISCO routers.

I will encourage you not to use USB as your network component. Always use RJ11, RJ45 etc. If you are considering connecting your laptop into your existing network, why cables? If you have money to buy laptop, buying a wireless PCMCIA NIC card would not brake your bank account.

If you already have a network, just configure the PCMCIA card and point the Gateway, and IP address of your router. If you router is configure with DHCP, you do not need to do anything.

On the other hand if you have not got a network, then these are the things you would need.

1. Router
2. RJ11 and RJ45
3. Hub
4. Broadband - from your ISP
5. PC's and laptop

When buying PCMCIA and other NIC cards, make sure you buy from 100/1000TBase, anyway most of them come with high bandwidth channel. If you buy 10/100Tbase, when network changes (It will change, definitely) you would need to buy all these NIC cards and related equipments again to take advantage of the higher bandwidth.

Hub, is good because it makes your network topology behave like start topology, hence no single point of failure will bring down your entire network. You can even add more topology to your star topology, by bridging one of your star segment.
