A Few Common Computer Errors

A Few Common Computer Errors

(And What They Mean)

Computer errors can pop up when least expected, they can cause the entire system to suddenly shut down, and they can inadvertently corrupt data to the point where it can’t be deciphered. Although they can’t always be avoided, it’s important to remember that computer errors can be corrected. The key is to understand what computer errors are, understand what they mean when they show up, and understand how to minimize their occurrence in the first place.

Basically, computer errors are the result of a number of things that may or may not have anything to do with the way the computer is used. They “operate” whenever there’s a conflict among commands. Remember that computers essentially run off of a series of commands and it’s usually a smooth process. But when one command conflicts with another command – or when one command asks for a process or information that isn’t available, the computer returns results that aren’t useable. That’s an error.

A prime example of this kind of error is when users attempt to use software that isn’t applicable for their system. Almost all software accompanies a list of system requirements which dictates what a computer needs to have in order for the software to work properly. To minimize errors of this sort, always verify that your computer has the required components. A project management program that you’re interested in may require a specific operating system, like Windows XP for example. And although this program may install just fine on a Windows 98 machine, it will generate a multitude of errors once its started.

Insufficient memory will cause errors as well. That’s why software programs include minimum memory requirements. A program that needs 14MB of memory will generate errors on a computer that only has 4MB of memory if it runs at all. The same goes for disk space, monitor color depth and resolution. In these situations, problems occur the moment that a piece of software attempts to access the things (hardware, memory, space, resolution, etc.) that it cannot find.

Because some programs share common files, errors can also occur when these shared files are not up to date. For instance, let’s say that Program A is already installed on a computer and it’s working just fine. Then let’s say that the user of that computer downloads and installs Program B. Program B uses a file that Program A installed much earlier, but when Program B is run, errors popup. Those errors are the result of Program B attempting to use an outdated (shared) file that was installed by Program A. In order to fix that problem, the user would have to download an updated version of the shared file (which to say the least – is not an easy thing to find or do).

Sometimes, errors occur because a system doesn’t have the required drivers or the drivers that are on the system are the incorrect version. Both errors in these cases can be resolved by updating the computer on a regular basis. Microsoft provides a section on its website that can automatically update a computer online and it does this at no cost in an effort to reduce errors like this. Always try to keep your computer updated so that should a program share a file, it will share a file that has been updated on hundreds of thousands of computers, like yours.

This article doesn’t even begin to cover the entire gamut of computer errors – but additional information regarding how to get help with a computer issue (including computer errors) can be found in our article titled, “Computer Help” no matter what the problem is.

Identify And Understand Home Networking Components

Identify As Well As Understand Residence Networking Elements

If you have not decided already, you will soon want to network your two or even more computers in your home. You wish to be armed to the educate with expertise of simply what it takes to link your computers to one another.

You initially should determine which network is best your you. If your computer systems are in the same space, the Wireless network must not be considered.The wired by cable television network must function simply great.

Computer system that may be close to each various other however can not be seen may and also have phone jacks close by can conveniently be networked with the HomePNA Network.While Computers that are much from each other can be connected with the powerline network, presuming wall outlets are nearby.

And when there are computer systems in different spaces and also you desire the convenience of moving the systems from space to room, the extra expensive Wireless Network is the way to go.After you pick the type of network that is finest for you, understanding what components you’ll require to purchase will certainly be a wonderful help.Let’s have a look at each network as well as the parts needed to obtain it up and running.

The WIRED ETHERNET NETWORK

If your computer systems are in the same room, the standard network package can wire your systems together.Be sure to meticulously open any type of package or element you buy as well as do not damage package it came in.The objective for this is to make it very easy to return the element if required.

Standard packages will have guidelines and software for the network as seen as two NICs.Better called Network Interface Cards, these NICs are installed in empty slots in the system unit.The PCI slot is where the card is installed and there are the USB adapters as well.The network will certainly need cabling to link the computers and also the CAT 5 or Classification 5 cable television is the one to search for.

Ethernet networks are available in two speeds, which are 10 and also 100mbps or megabits per second.The wired network will certainly also require a Hub or a Switch over to route web traffic from each system.If you want rapid website traffic, and who don’t, you will wish to connect a Switch over instead of a Hub.If you want all PCs to attach to the Web, a lot of kits feature Special Bridging Software which links the systems together.

The WIRELESS HOME NETWORK

Wireless networks count on radio frequency to transfer as well as get data.Wireless network equipment will provide you the option of both wired as well as cordless links.

If your computer systems remain in straight line of each other, the IR or Infrared regularity can be used.But most wireless networks now make use of the Radio Transceiver innovation with computers being located practically anywhere.

You will need a Wireless Router to link each COMPUTER to the network.Wireless NIC Cards need to be mounted in each computer in the network.When you purchase your wireless set, remember of the interior array.

As you can see when looking at the wireless Router, you have the alternative to wire your computers together must something fail with any kind of cordless component.Take note of the distinction between the wired nic as well as the cordless nic cards.

The POWERLINE NETWORK

The powerline network uses the electric wiring in your house to move data to and from each computer.Present powerline networks run in between 50kbps or Kilobits Per Second as well as 350kbps.

This network has a disadvantage in back it will have whole lots of electrical sound which will trigger the network to shed speed.And other PC individuals can snoop in your computer if they know just how.

This network will need a Router for information transfer and nic cards for every system.A Bridge will be required for access to the internet.These Bridges can be utilized with your Router.

The PHONELINE NETWORK

The elements you will require in the Home Network are close to that of the Wireless network.In most situations, the 10mbps rate network is quickly enough for residence customers.

The computers are attached with a Change, an entrance, or Router to share Web access and also to send out information to each computer system via the phone line network.This network is considered the simplest to arrangement.

Phoneline Network adapters are mounted in each COMPUTER. The USB or Global Seriel Bus port connection is the most commonly utilized adapter for Phoneline networks.To lower line noise, a Phone Filter may be needed.If you intend to attach a phone and line in one phone jack.you will certainly need to purchase a Line Splitter.Be certain each computer in the network are close to a phone jack.

The Phoneline Network is assumed to be less expensive.more reputable and quicker when compared to the Powerline network.

Essentially, all networks will need some type of adapter inserted in the computer.Each network will certainly need a center, switch, or router to move data.Windows 98, Me, as well as XP will have the needed software application to make everything work together.Adapters and as well as various other equipment will certainly feature tool motorist software which allows the equipment to speak with the computer system.

We have taken a short take a look at the equipment needed to network two or even more computers.Connecting the equipment was instead basic when we networked our computers making use of the cordless technology.Learn all you can around COMPUTER networking and you will be thankful in having this expertise needs to you experience computer troubles.

Considering that we have actually seen standard network components, its time to see exactly how each element is set up and connected.Then we’re visiting how to move data from one maker to the other as well as share the web using broadband with a DSL or a Cable modem.Remember to enjoy discovering your computer by doing as several tasks as you can without causing damages to your system.

A Basic Introduction to Computer Programming Topics

A Basic Introduction to Computer Programming Topics

Computer programming is one of the fields under computer science. While computer science refers to the study of computer applications, computer programming deals with the basics of a computer program – how it works, how it is designed, how it is fixed and why. If you’re planning to learn programming soon, here is an introduction to computer programming topics you’re likely to encounter:

The basics of computer programming
Like most disciplines, you will begin by learning the fundamentals of computer programming. Depending on your instructor or curriculum, you will probably be introduced to the history of programming and its languages and find out about what has occurred over the years through a timeline.

You will also be introduced to the basic concepts and theories of programming and how they have evolved over the years. You’ll be able to see how fast programming has progressed over the centuries and learn the significant developments in this field. You will also encounter topics such as computer hardware, software, systems and language. You will have to learn these basics in order to understand how your field of specialization can contribute. This may seem too troublesome but really, you need to have a good background in the progress of programming to help give you a good grasp of its fundamentals.

Computer software
The result of all your hard work is actually the computer software, so expect this topic to be included in your introductory course. Some of the topics you’ll find under this subject include application software, programming software and system software. During classes dealing with these subjects, you’ll learn how to use programming tools, database management systems, assemblers, debuggers, text and source code editors, and the like.

Programming
Finally, you will be introduced to the topic you’ve been raring to learn – programming. Here you’ll learn different types programming processes, styles and methods. You will learn the different types of programming including concurrent, functional, declarative (event-driven), imperative, object-oriented and Parsing.

Probably the next topics you’ll learn are the basic components of every computer program, such as the source code and the API or application programming interface. You’ll also learn how instruction is carried out to command a computer to execute a particular set of directions.

You’ll also learn programming languages, which will introduce you to the kind of language you have chosen to specialize in. Your instructor might also present your class with a simple comparison of the different types of languages in use today and you’ll also probably learn the types of languages that have lost favor or are already obsolete. You’ll learn semantics, dialects and theories.

This is also where you’ll begin learning how to program or write codes. Although your learning at this point will consist of lectures, a good part of your class will be spent working hands-on so you can begin practicing what the instructor has taught you. This is how your progress as a computer programmer will be evaluated.

The process of programming
One of the earliest topics you will encounter when learning computer programming is the process with which codes and computer languages are designed and produced. The process of programming includes several steps, such as:

1. Definition of the problem.
2. Design or plan of the solution.
3. Design of the code to be used for the program.
4. Testing and evaluation of the program.
5. Documentation.

Debugging, testing and maintenance
Probably the final list of topics you’ll learn as your introduction to computer programming is application. In these topics, you’ll learn how to test the program you have written, spot and locate any errors and correct them.
