It seems that every time I think it’s safe to ditch content from my CompTIA A+ classes, CompTIA resurrects a zinger. One of my students recently (on the 801 exam) got a question on parallel ports, or more specifically, on LPT1. Here’s the scoop on these long-dead ports.
Early PCs offered only one built-in port, a round DIN connector for a keyboard. All other expansion devices (mouse, printer, joystick, speakers, etc.) plugged into ports of various types installed via expansion cards. The two most common ports were serial ports and parallel ports.
We used serial ports for mice and modems, primarily, and parallel ports for just about everything else. Both types of ports required assignment of specific system resources that were standardized throughout the IBM PC universe and thus got names associated with them.
It was assumed that each PC would have up to two serial and two parallel ports that would get assigned resources as COM1 and COM2, and LPT1 and LPT2, respectively. Most technicians and users called the serial ports and parallel ports by their resource names, so “serial port 1” was “COM1,” for example.
Both serial ports and parallel ports have gone away from modern PCs, but a few old devices that need them refuse to die. My office still has an HP LaserJet 4, for example, that was made before printer companies realized the money was in toner and ink. It just keeps working. And it connects to a parallel port.
If you find yourself with a legacy device that needs a parallel port, you can find a few expansion cards at my favorite store, Newegg.com. Chances are you’ll assign LPT1 resources for the port. (Just in case you get asked about such things on a CompTIA exam in your near future.)
• Parallel port = 25 pin female D-sub
• LPT1 = I/O address 378 and IRQ 7
CompTIA announced today that they would be adding questions covering Microsoft’s famed Disk Operating System, released in 1981. “After much internal deliberation, we at CompTIA decided that the way forward is backwards. There are literally twos or threes of situations where an extensive knowledge of DOS would be vital for a modern PC technician.”
The spokesperson then continued, “For example, what if an A+ technician fell into a wormhole in the time/space continuum and had to find work fixing computers in the mid-80s? We at CompTIA strive to prepare our students for the unpredictable temporal topology that they’ll have to deal with every day as a certified technician.”
CompTIA also pointed out that DOS, a command-line operating system, is still used today in many businesses that have been cut off from communication with the outside world for the past 30 years. “It may surprise you, but a significant portion of our client base is in what we like to call ‘chronologically isolated communities,’ such as North Korea and Alaskan fishing villages surrounded by impassable glaciers. Also: survivalists who have been living in underground bunkers since the Cold War.”
This move, in addition to affecting current A+ students, may point the way towards a shift in CompTIA’s future plans for A+. At the press conference, CompTIA stated that they were also working closely with the Amish community to see how their technology needs could be addressed. Again, the CompTIA spokesperson, “We feel that an important part of studying technology is learning that technology is viewed by many as an immoral conceit condemned by God. While it’s impossible to know whether or not using technology is a sin, we at CompTIA are increasingly of the opinion that the chance is not worth taking. Future A+ updates will reflect this changing philosophy.”Read More

When you are someone who is invested in getting a job in the Information Technology field, you will find that certifications allow you to get your foot in the door. When you are considering what certifications will do you the most good, the CompTIA Network + certification, also commonly known as the Network+, is a great place to get started. What do you need to know about the Network+ and the Network+ Practice Test?
What Does the Test Cover?
Unlike the A+ certification that is administered by the same company, the Network+ presupposes a fair amount of prior knowledge about computers. Before you even start studying for the test, you are expected to have a fairly thorough grasp about basic computer hardware, basic computer safety and basic software needs. A Network+ Practice Test takes that basic knowledge and tests on you on networking in specific. You will be asked to explain what networks are and how they work. You will be tested on things like installation and configuration, and on top of that, you will also be tested on network management and security.
Who Requires the Network+?
There are many companies that find the Network+ desirable for their employees. Not only do they need to make sure that the prospective employee has a fair amount of experience in the field, the certification also shows them that you are capable of learning and being trained. Some companies that preferentially look for a Network+ certification include Dell, Sharp and Xerox.
Where Can I Go With Network+?
If you are looking at improving your job prospects in the technology field, the Network+ is definitely one important thing for you to investigate. It will help you get a foot in the door, and will show you know what you are talking about. Some positions which commonly hold Network+ certifications include: network administrators, help desk technicians, IT officers, cable installers and network maintenance technicians.
When you are thinking about taking the Network+ certification test, there are a few factors that you should be aware of. First, there are always 100 questions. The questions are divided up between simple multiple choice questions and performance-based questions. The performance-based questions require that the person being tested perform a specific task in a simulated environment. This is the practical end of the test, which tells the certification board that the person in question knowledgeable about networking. Every person is given 90 minutes for entire test, and a passing grade is to receive at least 720 out of 900 possible points.
If you are thinking about getting Network+ certification, CompTIA does have a few recommendations for making sure that you pass. First, the A+ exam, also offered by CompTIA, gives you a solid background for a great deal of the information. Second, the company also recommends nine months in the networking field before you proceed. While these are only recommendations before you take the test, following them will insure you have a leg up come test time. If need be, there are also prep classes and practice tests.
If you are someone who is invested in making sure that you have the right certifications that will allow you to move forward, in the technical field, see what Network+ can offer you.Read More
One of my students ran into a question on the CompTIA A+ Certification 801 exam the other day that had me scrambling for a Web search. The question asked about the type of memory used on a SIMM. What? SIMM? I haven’t talked about SIMMs in class or in print for a decade.
Historical scoop: We used single inline memory modules (SIMMs) back in the days when the fastest processor was an Intel 486 running at a whopping 66 MHz. Seriously. Today (read: since Intel came out with the Pentium CPU) every computer uses some kind of dual inline memory module (DIMM). A SIMM has identical electrical contacts on both sides of the stick; a DIMM has contacts that are unique on each side.
When my student mentioned the SIMM question, my response was historical: fast page mode (FPM) or extended data out (EDO). Those were the two memory technologies used on SIMMs. He just shook his head.
The SIMM question gave as possible answers only modern RAM types, like DDR or RDRAM.
An extensive Google session later revealed an obscure (to me) printer-only memory module on a SIMM . . . and it uses SDRAM. Here’s a link, in case you’re curious:
Don’t miss this question when you take the CompTIA A+ exams!Read More

The Value Of Certifications In The IT Industry
The IT industry is build on certifications and experience, which means if an individual doesn’t have one then they need the other. The tech industry is a large and varied industry with many specialties. Unlike other industries, it also doesn’t have a strong emphasis on traditional degrees. Instead, the tech industry focuses on many specialized certifications in different fields, one of the most notable being Network+. These certifications show two things: that you have the basic knowledge necessary to fulfill your job, and that you keep on top of current technology and protocols.
Certifications range from entry-level and student certifications to advanced certifications that command a high salary. In general, those with certifications will command a higher salary than those without. Many positions within the IT industry need certifications such as the Network+ to even be considered for hire, especially in lucrative government contracts.
The Different Types of Certification
There are three main types of certification that an IT professional would consider: Microsoft, Cisco, and Comptia. Each of these certification companies have a variety of certification paths that one can go down to advance and specialize their knowledge.
Microsoft certifications focus on supporting Microsoft products for the use of systems administration and help desk support, where Cisco certifications focus on supporting Cisco products for network and routing capabilities. These are two very different industries which means that an IT professional should choose the industry that they prefer before deciding which certifications they want.
Comptia is different from the other certificate vendors because they are not based on any specific product line. Rather, Comptia certifications test entry-level capabilities in general technology, and thus show an individual’s ability to work in any environment.
When To Get Network+ Certification
Network+ certification is an entry-level certification that is usually taken at the beginning of one’s career or even while still in school. The Network+ certification will show employers that an individual is aware of the basic concepts of networking and routing. This differentiates an individual from other job applicants and proves that they have the basic knowledge required to be a network administrator.
Network+ certification is required for many positions, and is often preferred over Cisco Certified Network Associate certifications for positions that want all-around knowledge and not Cisco-specific knowledge. Network+ certification is a single exam that can be arranged through a local testing center.
How To Study For Network+ Certification
There are many different ways to study for Network+ certification, depending on an individual’s preference for learning. There are physical classes by local IT centers, video lessons, audiotapes, textbooks, and interactive practice tests. The Network+ certification is best taken by people that have at least a small amount of experience in the industry.
What To Do After The Network+ Certification
Since the Network+ certification is an entry-level certification there are a couple of options an individual can take after Network+. There are other Comptia certifications for a variety of technologies that can help grow an individual outwards. Obtaining a Microsoft certification or Cisco certification after Network+ can similarly make an individual look more well-rounded and professional.
The Cisco certification path for networking is more involved than the Network+ certification, so it is often easier to take Network+ before the Cisco exams. The Microsoft certification paths, however, can show that an employee is able to handle both the networking and the system administration side of technology as well as opening up different positions to a job seeker.Read More

If you are someone who is interested in working in a technology related field, or even if you are considering how you can better your chances of getting a job in general, you will quickly need to learn more about A+ certification. A+ certification is something that is generating attention, but what does it cover and why should you have it? Should you have it at all? Before you decide on whether you want this certification or not, take a moment to review a few key facts.
What Does A+ Certification Cover?
At the most basic level, A+ certification declares that you are a competent computer technician. A+ certification is a vendor-indepdendent certification that allows you to state that you are familiar with computer software and hardware and that you have had some training when it comes troubleshooting. The test covers everything from hardware to computer safety to networking to personal devices like laptops and PDAs. Having an A+ certification states that you have a broad and generalized amount of information about computers and networks.
If you are not someone who is computer savvy, that is, you do not have a strong desire to work with computers or ascend through computer repair and design departments, then you will find that the A+ certification is an excellent workhorse certification to earn. While it does prepare you for work as an IT assistant or an IT helpdesk person, it is not designed to advance you into an upper-division IT personnel the way that more elaborate certifications will. However, becoming certified will show that you have more information than a layperson.
An A+ certification will earn you approximately 11 percent more within your first year of certification than you would receive without a certification. A+ certification is excellent to have in conjunction with other certifications, like Network+. Both on its own and as a supplemental certification, the A+ certification is an excellent choice for you.
Increased Familiarity With Computers
There is far too great an impulse to see our computers and our networks as complex machinery that few people understand. We set them up clumsily and with no idea why they go together, and when they break, it takes hours, days or even weeks to fix. If you are someone who uses computers on a regular basis, it is often worth your while to find out how to repair them. Instead of handing your computer over to repair personnel who will charge you for parts in addition to an hourly wage, you will know how to do the vast majority of simple computer fixes on your own. This is invaluable for an independent worker.
Foot in the Door
With so many IT professionals looking for jobs, it is important to distinguish yourself from everyone else. By making sure that you have A+ certification, you will be able to make sure that the individuals who are looking at your resume will give it a thorough inspection. A+ certification shows that you are someone who is interested in a wide range of training and that you can follow through with a project.
Take a moment to think about what A+ certification could do for you, your career and your ability to get ahead!
