The Computing Technology Industry Association offers a number of Certifications that enable IA techs to make their resumes look stronger and that also give employers a measuring stick for evaluating the skill level of an applicant. The A+ Certification is one of these and is considered an entry level general purpose vendor-neutral certification. It covers a wide range of skills related to the maintenance of personal computers. It also covers basic networking, security, safety, and even environmental issues.

A+ Certification training is available worldwide and is designed to prepare the student for the certification exam. There is a common misconception, however, concerning A+ Certification training. Many aspiring techs view it as a basic training course for beginners to the IA technology field. In planning their career path, they view the A+ training as the starting place for their overall training. This is a mistake. The Certification training programs are designed to prepare the student to take the comprehensive exam to receive the Certification. A certain skill level and educational background is going to be assumed of the students taking the training. If you have not received the elementary training, you are going to be over your head.

Certification training is not the starting place for computer technology. This training needs to start at the earliest possible time. It is like many other subjects like mathematics and language and it requires that the proper foundation be laid before advanced training can be undertaken. In mathematics, you can not expect to take a class to prepare you for an advanced algebra exam if you have never learned to count. Do not view certificates as the starting point. If you are serious about a career in computer technology, a review of A+ certification requirements would be helpful to guide you in the choice of classes or programs to acquire the basic foundation skills and knowledge.

The bus topology is a shared medium in that multiple devices are going to use it to send data. If one host is sending data, none of the other hosts can send data until the sending host is finished. Also, all hosts on the bus will see packets that are destined for one particular host.

A bus segment has to stop somewhere, and the signals transmitted by hosts on this particular bus will be stopped by terminators located at the physical end of the segment.

What do I mean by “single point of failure”? If we have nine hosts on a bus, only one can transmit at a time. That’s bad enough, but what happens if there’s a problem with the physical bus? There’s a big problem, because bus topologies are not fault-tolerant.

Then you’ve got nine workstations that can’t send data! The bus segment is a single point of failure – there is no backup way to send data, and an error anywhere on the bus will prevent data transmission by any host. Get used to looking for and preventing single points of failure, because these have to be guarded against in everything from physical network setups to routing protocols, and everything in between!

The only “benefit” to bus topologies is that it uses less cable than the other physical topologies we’re going to examine. Cables are pretty cheap, and the drawbacks far outweigh the potential benefits.

Now, why did I call this topology “dreaded”? There’s more than one reason:

The topology is shared, so only one segment can possibly send data at one time, which is highly inefficient

Bus topologies are not scalable. By “scalable”, I mean that we can’t add to it in an efficient manner. The more hosts we add to that physical bus, the more hosts we have that have to wait to transmit, the most hosts that have to examine the destination address of packets they won’t end up accepting, etc.

Bus topologies are subject to a single point of failure, and we want to avoid that at all costs!

I personally recommend you avoid bus topologies in the real world, but you must know all about them to pass the Network+ exam. In my next tutorial, we’ll look at star and ring topologies. Until then, keep success as your destination, and keep studying!

The new version of the CompTIA A Plus Exam released for 2003 has been totally stripped and reworked to cover the newest technologies. The Core Hardware Exam now covers the Pentium 4, USB 2.0, IEEE 1394a and Serial ATA, while the new OS Exam now covers all versions of Microsoft Windows from 9x to XP with the majority of questions leaning toward the newer Win2Kand XP versions respectively.

Here are some things you can do to ensure your success:

Read, Read, Read and Read some more:
Some people learn by doing, others learn by reading. Even if you are in the “Hands On” group of people it never hurts to read. Text books are expensive, use your local library. Thrift stores are a great place to look as well. Free study guides available on the web are great resource as well.

Take Notes:
Whether you are taking a class or doing self paced study, writing things down is great way to make them stick. Highlight your best notes for review on the day you take the exam.

Hands On:
Odds are, you have a newer computer or don’t want to risk damaging your own. Get some old computers from local thrift stores and garage sales. The cheap $10 or $20 ones will do just fine. If you can make an old IBM XT with an 8088 and MFM/RLL hard drive work, you will pass.

Study the newer technologies:
Real world experience, and any hands experience even with the older machines is a definite plus. However, make sure that you are familiar with the good amount of more recent technologies covered in the new 2003 revision of the A+ Exam (A Plus Exam).

Stay Focused:
We all have a life, just remember your goal. Once you successfully pass the CompTIA A+ Plus certification your future employment opportunities will be greatly enhanced.

Talk about it:
Take the opportunity to talk with friends and classmates. Better yet, other people who have actually taken the exam. Even those who have failed can give you pointers, especially on what to look out for.

Practice Makes Perfect:
The internet is filled with resources, take advantage of them. Take as many free practice exams that you can find. This will not only give you exposure to questions much like the ones on the test, but it will also prepare you for testing day as well.

Common Sense:
The A+ exam is multiple choice. So while you may not be able to memorize all the questions and answers to everything, use your common sense. If you can eliminate some of the obvious wrong answers you will have an edge.

Take your time:
You are paying for this test, two parts actually. That’s $290. You have 90 minutes for each test, don’t rush it; that’s how mistakes are made. Watch out for double negatives. Don’t let being in a hurry cost you $145.

Have Fun:
You should enjoy what you are doing. Once you get past the hard work and studying, this can be a very rewarding career path.

Things to avoid when preparing for the CompTIA A+ Plus Exam

Here are some basic study habits that apply to all situations:

Avoid distractions: Listening to your favorite TV show or blaring your MP3s while you are studying will not help you remember anything.

Avoid UnReliable Websites: The internet is a great place for research and gathering information. However; it can be a double edged sword. Be sure that you double check your information with a verifiable source if you are not using a reliable website.

Avoid Accessories On Exam Day: When you arrive for your exam, try to show up with the least amount of extra clothing or accessories possible. Every testing center I have visited takes the procedures and rules very seriously. This is an industry standard test and should be revered as such.

Avoid Outdated Material: A lot of study material on the internet may not cover the latest objectives. Ensure that you are studying from the latest exam objectives.

Avoid Time Hog Questions: Do not Spend too much time on any one question. If you are unsure, answer it the best you can; then mark it for review after you have finished the rest of the questions.

This certification was first introduced in 1993. Today, there are about 600,000 professionals who have this certification. There are no prerequisites to get this certification. However, this validation is used rather as a starting point for a number of network administration and system administration certifications. For instance, one can use the A+ certification, combined with either the CompTIA Network+ or Server+ certification, as an elective for Microsoft’s MCSA certification.
At present, the examination is undergoing a transition to the 2009 edition of the certification. However, the 600 series is also applicable for the time being. Candidates looking forward to be certified in the 600 series A+ exam will have to take two qualifying exams: the 220-601 A+ Essentials in addition to one another from the three elective paths listed by the organization. These three paths include the A+ Certified IT, Depot Technician and Remote Support. On the whole, there are about four exams available today. However, a professional is required to take only two for any of these three paths.
The objective of A+ certification is to endorse the competency of IT professionals as computer technicians. Though it is said that this is a vendor neutral examination, one can see that it bends towards Microsoft operating systems. The newer examinations feature some Apple questions also. A+ Certification has been launched by CompTIA, a non-profit organization. The organizations website comptia.org offers all the required information about the exam. Though this exam is not treated as an essential prerequisite for any other certification, you will find that it offers a natural lead-in to other CompTIA certifications, including Network+, Server+, Linux+, Security+, iNet+ and others. Today, this is the only certification focusing on PC Maintenance available in the industry. Securing A+ Certification requires a thorough knowledge in several areas of Microsoft Windows in addition to the IBM style of personal computer. If you attempt to get the A+ Certification, you need to have approximately 500 hours of work experience with computer hardware, system files, operating systems, maintenance, networking, repairing computer problems and configuration of hardware and software.
