Computer Programming Certification

by: gaobin

Although there has been a lull in recent months in the IT industry there is still a requirement for those people who have trained and gained the qualifications associated with being a computer programmer. Getting your computer programming certification could be extremely useful in the future and is very easy to achieve today because of the number of online training programs now available.

Also obtaining your certification as a computer programmer will not only provide you with confidence in your own skills and abilities but will make others look on you more favorably when applying for a position. Plus through doing such a course you will find that you can then move into the newer areas of this particular field of the IT industry as and when the much older forms of programming are phased out and replaced.

Through the use of an online course a person is able to pursue their dream of becoming involved in this part of the IT industry at a pace that suits them. Certainly for those who are currently employed doing their studies online means that they can still carry on earning a wage whilst gaining their qualifications, which will result in them actually getting a better-paid position in the future.

What actual course you actually do will depend on your level of expertise and experience. There are ones, which have been specifically designed for those students who are complete novices and are only just looking to become a computer programmer. Whilst there are other courses, which provide the students who have the knowledge and experience to further, enhance what they have and teach them about the latest versions of computer programming software that is available on the market.

When it comes to you finding the right school or course there are certain factors that you will need to take into consideration. Firstly it is important that you look for one where the qualifications that you obtain are actually recognized by companies. Therefore it is best if you choose to get your computer programming certification through an accredited school. Going online you will find a list of all schools that are accredited and can provide you with the course or courses that you require.

Secondly once you have found a school that you would be interested in attending you need to carry out some research in to the computer programming certification course they offer. Look closely at what kind of reputation the school has with regard to the qualifications and training it provides. Also look closely at the content of the curriculum, does it match what you are looking for. Also take a close look at just how many students they place into each class. The bigger the classes then the less chance of you being provided with the right kind of support you need.

Cisco CCNA Home Lab Study - The DTE & DCE Cable

by: gaobin

More Cisco CCNA, CCENT, and CCNP candidates than ever before are putting together their own home labs for their certification exam study, and that's a great trend - there's nothing like learning on the real thing!

Part of putting a home lab together is getting the right cables and understanding their usage. In this new Cisco home lab series, we'll take a look at the different cable types and how each fits into your home lab. The first cable type we'll look at is the multi-purpose DTE/DCE cable.

When I say "multi-purpose", I mean that while the cable will always perform the same task, it can be used in several different points in your home lab network. If you're going to have a frame relay switch - and you should get one if at all possible, since having your own frame relay cloud is a tremendous boost to your home lab studies and your exam score - you're going to need a DTE/DCE cable.

You can also use a DTE/DCE cable to directly connect two Cisco router serial interfaces and configure HDLC (the default) or PPP encapsulation over that point-to-point link.

Most of today's DTE/DCE cables have "DTE" clearly stamped on one end of the cable - actually, "DTE" is probably embedded into the connector itself. Naturally, the other end will have "DCE" clearly indicated. It's the DCE end that will connect to your frame relay switch. If you're going to use a direct connection to run PPP or HDLC, it almost doesn't matter which end of the cable is connected to a given router.

Keyword: "almost". You must use the clockrate command on the DCE end of the connection in order to bring the line protocol up.

If you're not sure which end of your DTE/DCE cable is connected to a given serial interface, just use the show controller serial command to get that information. Most of the output of that command isn't comprehensible, but what we need is right on top:

R3#show controller serial 1

HD unit 1, idb = 0x11B4DC, driver structure at 0x121868

buffer size 1524 HD unit 1, V.35 DCE cable

Naturally, if it's the DTE end, you'll see "DTE" there. And if you don't have anything connected to that interface, you'll see "no cable".

Whether you have your own frame relay switch or not, you'll want to pick up some DTE/DCE cables for direct connections between your Cisco home lab router's serial interfaces. Just don't forget to put the clockrate command on the DCE end of the cable! And if you're not familiar with a frame relay switch, check this same website soon for a tutorial that will show you how to set one up.

Just about any Cisco router can serve as a home lab frame relay switch, and once you've got it configured, you're in good shape - but it can be a little maddening to get it up and running in the first place. I'll show you how to avoid that aggravation in the next installment of this Cisco home lab tutorial series!
