Web Cameras
Web cameras are great equipment for your computer. They are basically digital cameras that transmit images to the computer. Web cameras have increased in popularity with the higher number of people using them to chat with friends and family around the world.
A Web camera functions by taking a number of frames, or still images, within a short period of time. Using computer software, these frames are then played together quickly to generate the look of streaming video. A frame rate of 30 fps is recommended for any web camera you purchase.
When selecting the right Web camera, it is necessary to think about the resolution that the Web camera offers. If the Web camera is to be used for video conferencing, choosing a camera with the highest resolution, or your image might appear blurry or grainy.
Computer Speakers Are a Must Have
Even if your computer is a laptop and comes with speakers, it is beneficial to buy another set of computer speakers. Computer speakers can be purchased either online or at your local computer store. Have an idea of where you will place your new computer speakers before selecting them. Since computer speakers vary in size, there might not be enough room on your desk to place them near your computer.
It is definitely recommended that you listen to the sound quality of the speakers before deciding to buy them. It is possible to determine the quality of computer speakers by testing them using music or a CD. Many computer stores will have computer speakers on display, which are hooked up to a radio, so you can judge the sound quality for yourself.
Ergonomic Keyboard
Repetitive typing on a keyboard is one of the most common causes of carpal tunnel syndrome. In order to reduce your chances of developing injury to your wrists, arms, shoulders, and neck, consider purchasing a keyboard that has been designed ergonomically.
A keyboard that has been ergonomically designed will reduce the injury caused by constantly typing. Ergonomic keyboards vary in design from keyboards that are split or bendable, to keyboards that provide a resting area for the wrists. Regardless, of what design you choose, investing in an ergonomic keyboard can reduce injury to the muscles, tendons, and nerves of the hands, arms, and shoulders.
Not All Mice Are Created Equal
Other than how the mouse feels, there are other features to think about. Some mice can be purchased with more than one button and commands can be attached to the extra buttons. It is also possible to buy a mouse with a scroll wheel located on top. A scroll wheel is ideal for people who spend time surfing the Internet and scroll through lots of pages. Another Web surfer favorite is the optical mouse. An optical mouse does not have a rolling ball to the bottom of it and can be used on almost any surface.
Choosing The Right Scanner
There are three basic types of scanners to choose from, and the one that is right for you will depend on how the scanner will be used.
Flatbed scanners are the most well known. They are constructed using a glass plate, and the object to be scanned is placed face down onto this glass plate. The scanner head will scan the book, photo, or document and transmit the scan image to the computer.
The second type of scanner is the Sheet Fed Scanner. This is often used in offices to scan documents or business cards. Instead of placing the document face down on a glass plate, the document is pulled through the scanner and a copy of the document is transmitted to the computer.
Handheld scanners were welcomed with open arms when they were first introduced. Think carefully about buying a handheld scanner when you would like to scan only different parts of a document and not the whole page. This will save time and allow you to compile reports faster. Usually a handheld scanner is quite small and resembles a pen.
Protecting Yourself
A surge protector is an efficient way in which to protect your computer from sudden surges in electricity. These surges can send a bolt of electricity throughout your computer resulting in damage to essential parts such as the hard drive or motherboard.
When choosing a good surge protector, look for one that is designed especially for computers with indicators to tell you it is working properly.
Can My Computer Support a Scanner?
Not only is checking how the scanner will connect to your computer important, try to discover if your computer is able to support the use of a scanner. This would include having enough space to install the scanner software, having enough disk space to store the scanned images, possessing a fast enough microprocessor, and having enough memory to run the program. To avoid any problems, write down your computerĄ¯s specifications and take these specifications with you when looking for a new scanner. All scanners will have the recommended computer specifications in which they work best at, written on the outside of the box.
Types of Modems
All the latest dial-up modems will connect at a speed of 56K, meaning it can transmit data at 56 kilobytes per second. This type of modem also has the ability to send and receive faxes as well.
If you would like a better ISP package, consider signing up for cable or DSL Internet. Using a DSL or cable modem gives you the ability to surf the Web and still talk on the phone at the same time. This option is not possible with a dial-up connection, which is often slow and blocks you from receiving calls while you are online. A DSL connection will use your existing telephone line, whereas a cable Internet connection will use your existing cable television line.
Test Drive Your Mouse
For most people, buying a new computer mouse might seem like a quick task ¨C walk into the computer store and buy the cheapest mouse. However, the cheapest price does not always guarantee quality. It a good idea to spend time test driving a variety of different mice before selecting the right one, which may not be the cheapest one.
Wireless Keyboards
Eliminating the use of wires dangling from computer cases or other electronics is turning into a very popular trend. Wireless keyboards allow the user to be able to move around the room, but still be able to type information into their computer and watch it show up on the screen.
Wireless keyboards depend on infrared beams for communication between the keyboard and the computer. Wireless keyboards are especially handy for someone who might be bed-ridden or for any other reason in which they are unable to sit in front of the computer.
Scanner Interface
As with any electronic equipment, it is good idea to make sure it is compatible with whatever you are going to attach it to. Scanners often need a USB cable to attach to the computer case. Some scanners can attach using FireWire, SCSI, or a parallel port. Usually older scanners will have only the ability to attach through a parallel port. Therefore, it is possible to see the different problems that can arise with an old computer without USB and a USB scanner, or a new computer with USB and an old scanner with only parallel port attachment. This is why it is necessary to check the interface before buying your new scanner.
How Comfortable Is Your Mouse?
It is encouraged that you see how your new computer mouse feels in your hand before making the purchase. This point is especially important for people suffering for carpal tunnel syndrome, or anyone with arthritis in the hands and shoulders. By holding the mouse and practicing opening documents and dragging files, it is possible to determine if the mouse is comfortable for you to work with. Buying an ergonomic mouse can help increase your level of comfort as well.
Buying a Modem
A modem is needed for anyone wanting to surf the Internet. These days most desktop and laptop computers can be obtained with a modem already included with the unit.
However if you need to buy a modem, there are a number of choices to make. First, it is necessary to decide if you want an external or internal modem. An external modem is usually a little more expensive than an internal modem, but the setup for an external modem is easier.
The second choice you will have to make is the type of modem to purchase. There are basically three types of modems to choose from: dialup, DSL, and cable modems. The modem you select would depend on the type of connection your ISP is providing.
Connecting a Mouse to a Computer
First it is necessary to investigate how the mouse will connect to your computer. All new computers will have USB ports and these ports can be used to connect the mouse to your computer. However, if you have an older computer without any USB ports, and have purchased a new mouse, you might realize there is no way to connect it to your computer. Therefore, it is important to consider how the mouse connects to your computer.
