Computer lessons for beginners : how to use a computer mouse

Learn how to hold the computer mouse:
Hold the sides of the mouse with your thumb on one side and ring finger or pinkie, which ever feels more comfortable to you, on the other side. Your index finger goes on the left button and your middle finger on the right button. (Some computer mice only have one button, some have several, some have a wheel which you can use your middle finger to depress the wheel then turn it up or down to scroll pages very quickly or slow depending on how quickly you turn the wheel. Personally I love the wheel and would not have a mouse without it!) When you are told to ‘click’ use the button under your index finger, or the left button.

Learn how to move the computer mouse:
Slowly slide the mouse around on the mouse pad. See what happens to the arrow on the screen as you slide it around.

Do you need a mouse pad:
You should have a mouse pad under your mouse, (although the new optic mice do not require one). You will have an array of choices when purchasing a mouse pad; find the one that is comfortable for you. Rest your hand on the mouse pad or desk and move it slowly, there is no need to lift the mouse off the mouse pad unless you run out of room, then you just lift it up and reposition where needed. You don’t need to move the mouse to the left or right, simply slide it left or right with the buttons still facing away from you.

6 Tips For Saving Money On Your Next Computer Purchase

Buying a Computer does not need to be a budget breaker. A Computer purchase often includes additional components and software that are not needed and can be avoided…if you are well prepared with the correct information.

To help, the following tips can be used to save money on your next Computer purchase:

Tip #1 – Take a look at your Computer case. If it is not a name brand Computer more than likely the case is expandable and can be reused. Cases can cost anywhere from $25 to $100. If you have a mid tower case, check how many bays are available for CD/DVD drives, and other peripherals, Are the USB and audio ports in the front?

Cases are often an over-looked item that usually can be used over and over again.

Tip #2 – Monitor Keyboard and Mouse – Just because you are purchasing a new Computer does not mean the keyboard and mouse need to be replaced. An Optical mouse last longer than the ball style mouse. The same principal applies to keyboards, unless you are a heavy Computer user and the keys are worn and do not respond, you probably don’t need a new keyboard.

Monitors may need to be replayed if want to upgrade to a larger screen size. If you are happy with your monitor and are having no problems with it, you are better of keeping it a little longer until you can afford a new Monitor.

Tip #3 – Software License – Many people forget when purchasing a new Computer the cost of the Operating System license is included in the price. If the new Computer has the same OS installed, don’t pay for another license.

The same applies for other software such as Microsoft Office. Unless you want to upgrade to another OS or Office version, save your money. Significant savings can be realized by not purchasing un-needed software license costs.

Tip #4 – Consider No Name Brand – While Dell, Hp and Sony are some of the big names with Computers, the reality is that most Computers originate from the same area in Asia, specifically laptops. Consider shopping for lesser name brands, or visiting your local Computer repair store.

Unknown brand names such as Acer, are usually cheaper, yet inside the case or laptop, the parts are the same. Computer repair stores allows for customization, so you can tailor to your need, not by what is on the shelf allowing for more savings.

Building a Computer From the Bottom Up

Before you even think about building your own computer make sure that you go for the best technology possible. This is an important task and you want it to turn out as close to perfect as possible. When your PC is complete you want it to have the best hardware available.

One of the biggest benefits of building your own computer is that you can customize it. You know what is most important to you. Maybe you are a graphics user. MP3’s might be the closest thing you have to a best friend. Perhaps you are writing the great American novel and you are mainly interested in text. If you are building your own machine, you can concentrate on what you want but if you’re building it for a third party, you obviously need to consult them first.

Collecting the hardware for your new computer is the most time consuming part of the process. You want to make sure that you get high standard equipment that works well with your needs. Take your time and don’t try to skimp on your hardware. If you don’t heed both of these suggestions, your computer could bite back later.

If you are building your own PC, you probably know that the Motherboard is the most important part of your computer. Everything that you plug into your computer will meet here. Be especially choosy when buying a motherboard. And make sure that there is an instruction manual. Some cheapies will not have one.

Be aware that the Motherboard will control the future of your computer. All upgrades will have to be compatible with your Motherboard. The chipset in the Motherboard deserves careful investigation. What will it support? Find out before you buy. Take your time. There are a ton of chipsets out there.

Pay close attention to how many PCL slots the Mother board has. The more, PLC slots the better because they fill up quickly. How is the board laid out? Check for any problems such as something blocking your long PCI slots.

When selecting a case, be aware of the form factor. You want an ATX form factor because that is what almost all new systems are operating on. Try to go with a screw free form factor because it will be easier to work with. One equipped with fans would be optimal.

Three are three groups of processors; low end, average and high end. The low end processor is okay for simple tasks. Letters, invoices and other noncomplex applications can be performed on a low end processor. If you do choose to go with a low end processor, realize that these are fast becoming outdated.

Average processors are faster and they are just a bit more expensive. For a few extra dollars you will be able to access higher level applications without hassle. This will provide more speed as well satisfying the average computer user.

High end processors are the cream of the crop. They are expensive and usually reserved for those on the high end of the pay scale. You will have high memory and no problem accessing complex CPU programs.

Cabling your home for computer network – still a requirement?

Cabling your home for computer network – still a requirement?

With proliferation of wireless networking and communication equipment it is oh-so-tempting to cut the cord and save a significant sum of money in the process. But is everything that a regular computer networking user needs can be done using just wireless network? Let’s take a look at some pros and contras:

1. One important advantage of having a cabled network is the available bandwidth or simply speed. At the present point in time the speed of connection via a simple and inexpensive CAT5E cable can be 1000Mbit/sec, whereas the best that IEEE802.11g (one of the many flavors of Wi-Fi) can offer is only 54Mbit/sec. It may not seem so significant if you think you are only browsing Internet, and the DSL speed available to you is 1.5Mbit/sec. However, if you need to print via your network connection on a remote printer, you should realize that the print jobs, depending on the amount of graphic data in them, can easily reach dozens and even hundreds megabytes. Since 1Byte=8bit one 100MByte print job will take 15 seconds (and in reality this time can be much longer) to transmit via a Wi-Fi wireless connection, and this time shrinks to mere 1 sec or less on wired 1000MBit/s Ethernet connection. Same principal applies to transferring files, backing up files on other computers in the network etc.
2. It is not possible today and with all probability will not be possible in the future to transmit power needed for your networking device via the wireless link. Unless, of course, you would be willing to be subjected to very high levels of microwave radiation. Thus a device that was marketed to you as “un-tethered” will in fact be very much tethered via the power cord or will have to be re-charged every so often. The power requirements are increasingly important for devices that are expected to be always online, such as phone sets. Therefore it is best to have it connected via a cable that can deliver both power and the communication signal at the same time.
3. Wireless communications are very much proprietary and require whole gamut of conversion equipment to transmit multi-media signals. The same CAT5E cable can without any modification support phone, computer network, balanced line level audio signal, baseband video signal as well as host of other, more specialized, control applications’ signals. With inexpensive adapters called “baluns” the same cable can carry significant number of channels of broadband television or carry a baseband video, such as security camera output, through great distances. All of those applications, except the computer network of course, will require specialized expensive conversion equipment if they needed to be transmitted via a Wi-Fi link.
