Knowing Basic Computer Terminology Helps Support Staff Help You
Knowing Basic Computer Terminology Helps Support Staff Help You
When you know and understand the correct terms to use, getting assistance for your computer software is much easier. Not knowing how to describe the problem correctly to technical support is one of the biggest problems for new computer users. Below, you will find the correct terminology for the common components of software.
1. User Interface
This is the programs outward visual design. It can contain buttons, icons, boxes, words and squares. If your PC experiences insufficient memory, there may be black rectangles that appear across the user interface of your software programs.
2. Menu Bar
This will display menu items or options. The most common parts of a menu bar will grant access to File commands, Save commands, Open commands and Print commands. An error in this part of the interface will produce a missing option or one that is of a lighter color.
3. Title Bar
This is the area at the top of the program, where its name is displayed as well as where there may be a description of the contents displayed on part of the interface. An incorrectly coded program may produce a wrong description in this part of its interface.
4. Status Bar
This is located at the bottom of the interface, generally displaying small messages, indicating the progress of a command or task. Incorrectly programmed programs may display the wrong information in this area.
5. Tool Bar
This will display small icons on the top of the screen as representing tools. Clicking, an icon opens a tool or processes a command that might also exist on the menu bar. Problems in this part of an interface are uncommon.
6. Minimize, Restore, and Exit buttons
These three buttons are normally located on the right upper part of a program interface, each allows you to minimize the screen, restore it to original size, or shut the program down.
7. Context Menu
Right clicking on something will display the context menu. It displays in much the same way as a Help menu.
8. Scroll Bar
This tool allows a user to move the displayed part of the user interface up and down on the computer screen.
9. Buttons
Buttons perform commands with the click of a mouse. Problems may exist when the text button is grayed out or if it does not seem to sink into a screen when clicked.
10. Input Box
These normally small rectangles allow for entering data into a web page interface. If you cannot use one of these boxes, it may indicate that the program is faulty or that communication with the external network has been compromised.
11. Check Box
This small box displays several choices. When clicked a small x displays inside a box, it allows you to choose between many options displayed on the user interface. Inability to enter an x may indicate that the program has stopped functioning and must be restarted.
CNC Programming Tips the Professional Way
CNC Programming Tips the Professional Way
When a program is completed and sent to the Computer Numerical Control Machine, the programming process is over. All calculations were made and the algorithm fully written. But the question is the programmer’s job really finished? When is the programmer’s responsibility really over? And how can we evaluate the type of program that the Computer Numerical Control Machine programmer did?
The fairest and reasonable answer to those questions would basically when a part has been machined under the most optimized working conditions. Therefore the Programmer’s responsibility does not end after he or she finishes the program. We could say that the program at this stage is still very much in the development process, because most of the programming considerations were based on certain assumptions and there are a lot of external factors that may affect the outcome of the product.
Every Computer Numerical Control programmer should have an effort to be in the touch with the actual production. In the field of software development, Constant communication with your colleagues as well as actual machine operators of the CNC will help you to improve your own program. Because most of the time the CNC machine operators are a good source of constructive ideas, improvements and suggestions.
A good CNC programmer should talk, ask questions to them and most importantly listen to what they have to say. Programmers who never put their foot in the actual machining process and think they are always right are all on the wrong track. Exchanging ideas with CNC machine operators, asking questions and seeking answers is the only way to be fully aware of what is going on in the machine.
Whenever you start a Computer Numerical Control Program the first time it is important to check its Program Integrity. A new and unproved program is a potential source of problems. During Manual Programming in CNC, mistakes are more common than when the program is made in a CAM program.
A good way to look at a new program is through the machine operator’s perspective. Experienced Machine Operators take a direct approach when running a program for the first time. That means that they wont take any chances of mistakes with the actual running of a program therefore a good programmer must take note of any comments that the Machine operator will say about the program.
What does an experienced Machine Operator look for in a new part of a program? Most of the Machine operators would say that the first and most important thing to be checked on a Computer Numerical Control Program is its consistency. Therefore a machine operator looks at how a CNC programmer does its own programming, is the way you create your own algorithms the same as the other ones. Machine Operators take note with this kind of Information.
Upgrading your CNC Program
Whenever you upgrade your own program, it means that you are strengthening or enriching it, therefore making it better than it was before. Upgrading would be based on this standard, It is to decrease the production cost without compromising the quality of the part being manufactured or the safety of the Computer Numerical Control Machine Operator.
One of the Most Common forms of Program Optimization is doing some minor changes to the spindle as well as the feed rates of the machines. This process is called cycle time optimization, slightly increasing the spindle speed and feed rates of these machines will decrease the time it takes to finish the part.
And when we compare it to mass production, saving one second for each part in a batch of 3600 pieces would mean an hour saved. Efficiency in the rate of production is a very important aspect in Mass Production.
The Computer Forensic Toolkit
The Computer Forensic Toolkit
Computer forensics has been garnering a lot if interest due to the increase of cyber crimes. The need for computer forensic experts is steadily increasing. As the technology continues to develop criminals and offenders find a way to catch up. The Computer has become an important part of your lives.
It has changed the way we work and live. This is why it has become the target of criminals and offenders. Computer forensics helps combat crimes. It is also necessary for them to avoid mistakes and make sure that they do their job. Fortunately a computer forensic toolkit is available to make sure that they got all the bases covered.
Computer forensics is complex. It needs careful preparation and procedures must be followed diligently. It may look easy in television but computer forensics takes a lot steps. If any of these steps are missed the evidence can be tampered. The evidence will be inadmissible in court and the computer forensic analyst may face a lawsuit.
The right tools for the right job
Like any other job we need the right tools for it. These tools are important to be able to do your job well and avoid mistakes as much as possible. If you’re a computer forensic expert you cannot afford to make a mistake. Any evidence should be handled carefully and properly.
Any IT professional can retrieve data but they are not trained in evidence techniques that are necessary for the job. In most cases the computer system is taken from owners even though they have provided consent. If the data and the machine are compromised the computer forensic analyst may face a lawsuit.
The computer forensic toolkit reduces the risk of making mistakes while doing your investigation. It also serves as a guide and framework to be able to have a smooth investigation. It also serves as en educational guide for newcomers that will provide the technical and legal know how to a forensic investigation.
A computer forensics toolkit is available online. Unfortunately it not free and costs 9. It’s a comprehensive guide for both the beginner and the veteran. To keep with the continuing changes in the technology tools such as these are important for a faster and more efficient forensic investigation. Computer forensics is not exactly one of those jobs wherein you can erase your mistake and begin over.
The whole tool kit can be viewed in MS word format for easier reading. The first part of the toolkit is the Introduction and Guide. It contains a comprehensive overview of computer forensics with an outline for the whole procedure. The next is Management Presentation. It is followed by forensics report template which provides a guide in making consistent reports.
Essential Forensics Forms, as the name suggests contains all requisite forms for documentation. Manuals and Procedures contain all the steps done in the forensic laboratory. Forensic glossary contains all the terms. Forensic resources contain the FAQ, cost estimator, case studies and valuable tips.
There’s checklist to keep track of your progress. The last but not the least is the Tool Reference Catalog which contains the list of documents and software tools that you need.
The toolkit will provide the know how for any newcomer and a reviewer for the veteran. Every analyst should keep abreast with the times to make sure that the criminals won’t overtake them.
Scuba Diving Computers Required
Scuba Diving Computers Required
More and more dive operators are making them mandatory. Some even include a wrist dive computer as part of the gear provided to their customers. This is especially true for live-aboard dive boat operations.
Of course that only makes sense for these “dive your brains out” deals. You’re doing a ton of diving, spending serious time underwater, and a computer not only makes it easier, but helps avoid compromising safety.
And don’t misunderstand, live-aboards are great. It doesn’t get much better than five or so dives a day, and merely rolling out of bed to get to the site. Put that together with great food, pristine reefs off the beaten path, & falling asleep under the stars, and it’s a super vacation recipe.
Aside from their obvious usefulness in the live-aboard world, dive computers make sense for most all diving situations. In fact, anyone serious about the sport shouldn’t make another dive without one. From maximizing bottom time to calculating complex dive plans without compromising safety, these wrist computers are invaluable.
Even the dive operators who don’t make them mandatory, will separate the computer divers from the non-computer divers, requiring those without personal dive computers to follow a much more conservative profile, which most often results in a shorter dive.
Now there’s nothing wrong with being conservative, but not to the extent of cutting a dive needlessly short. And that’s the whole point behind using a computer. It allows more time at depth and/or underwater while still helping you stay within safe limits.
There may be a handful of very experienced scuba divers who are so skilled with the dive tables, they can recalculate complex dive plans on the fly during their dive with some proficiency. But even they can’t beat a computer in terms of speed and accuracy. And most, if not all those guys, still use a computer simply because they prefer to get the most from their diving.
Whether you need the full functionality of variable gas mixtures, extensive dive logging, complicated multi-level dive profiles, deep or decompression dives, etc., or just want to stay safe while allowing for slight changes to your dive plan, a good dive computer is an excellent investment.
They really should be considered required equipment. Prices have come down so far that cost just isn’t an excuse anymore, especially when thinking about safety. Get the most out of your diving by making a wrist computer an integral part of your dive gear.
