If so, you need to invest in an expansion card. This is an add-on card that is inserted in the expansion slot of a computer to increase the PC’s capabilities. There are various types of expansion cards, including:

• Video cards
• RAID controllers
• Sound cards
• TV tuners
• Network cards
• Peripheral device cards

These are just a few of the expansion cards that you can have on your computer. Below are some the benefits of these cards and reasons why you should consider investing in one or a few for your PC.

1. Improve Video Capabilities

You can use a graphics card to improve or enhance the video capabilities on your computer, especially if its performance lets you down when you need to game, run sophisticated software, or watch high-definition video content. A graphics card upgrades your computer and allows you to play games that would otherwise not be possible. What’s more, you can watch HD movies and videos on your PC without experiencing picture distortion. A graphics card will also make it possible to run sophisticated software such as design, coding, and programming software without slowing down your PC.

Do you need extra storage space for your computer and aren’t ready to invest in a new PC? If so, there are expansion cards that you can use to make this happen. RAID controller expansion cards give you extra ports for connecting multiple hard drives to your computer. You can plug in additional drives to expand your space. Top computer repairs Sydney firms will recommend high-speed connections such as SATA cables to use with your expansion card.

3. Watch and record TV

TV tuners and sound cards make it possible for you to watch and record TV on your computer. This is a handy feature for those who wish to access TV at the office or other areas where they may not have access to a TV. They also allow you to record shows and watch later, a feature that is not available in most of the 19th and 20th-century televisions.

4. Increase USB port speeds

It is a no-brainer that standard USB ports can be slow and annoying. This is particularly true when you need to transfer large files from an external device into the PC or vice-versa. If you regularly carry out this kind of transfer, you can benefit from peripheral device cards which significantly increase the speeds on your USB ports. And allow you to transfer data faster.

Expansion cards can take your PC performance to the next level, but they need correct installation to function properly. Luckily, you don’t need to carry your desktop to a PC shop to get the device installed.

In 2005, more than a billion mice were estimated sold worldwide. Since the early 1990s, the mouse was used for almost all computer activities, along with the monitor and the keyboard.

The very first prototype of a computer mouse was built in 1963 by Bill English after drawings by Douglas Engelbart. In 1984, the Apple Macintosh, which shipped with a mouse as the primary input device. So this became a larger distribution for the first time.

How a computer mouse works

The user moves the mouse on a flat surface, the motion information is transmitted to the computer. Regarding operating system routines, a marker (cursor) is moved on the screen according to the mouse movement. In most cases, the graphical marker is displayed as a small arrow.

The mouse is equipped with buttons that convey a registerable activity for the appropriate keystroke (mouse click). In such an event, usually the current screen coordinates are calculated and a corresponding reaction is triggered.

For example, a user may point to a file icon and select it by pressing a button and activate it. The program registers the file icon and raises out graphically, which can be handled by Dell Computer Repair Sydney.

In a word processing program, a user can move the cursor in the text and with one keystroke (cursor) position in it. When the user starts typing, the text will be inserted at this point. Distinction between different processes for receiving mouse motion.

The first mice functioned with mechanical contacts . In the very first generation of sliding contacts yet been used for coordinate determination but were subject to heavy wear and are very energy efficient to evaluate.

Opto-Mechanical

Later optomechanical mice were common, in which the mouse movement is converted via a roller ball , two perforated discs and associated light sensors into electrical signals.

The rolling motion of the ball is transferred to two perforated segment slices over two rollers , from the direction of rotation and speed are incremental with small photocells electrical impulses it produces. The relative coordinates of the mouse cursor to be calculated in the computer with appropriate software (mouse driver).

However, ball mice are susceptible to pollution because the ball , usually a rubber-coated steel bullet, repeatedly pulls particles into the mouse inside and this stick mainly to the mechanism , which can reduce the accuracy and repeatability of the mouse.

Also, exposure to strong sunlight may affect some mice with slightly translucent housings by interfering with the light barriers.

An advantage over optical mice with an image processing processor is the lower power requirements (25 mA to 100 mA at an optical mouse). On older computers are still many of these mice in use.

Some mouse will get broken easily, try to visit computer repair store to check what’s the issue on it.
