How Computers Benefit Society

March 15th, 2010



Computers are wonderful machines. They are everywhere and society depends on them to manage our world. It is no wonder that computers have almost unlimited applications, and that they are multiplying at a steady rate. Many of these applications are benefiting society directly or indirectly. The three most important ways computers are benefiting society, is by, creating more information technology professions, creating new automobile safety features, and opening ground-breaking communication methods. There currently exist many other beneficial functions of these machines, such as their use for diagnosing patients, running weather simulations to predict future weather patterns, and calculating large, complex data sets. As new applications emerge for computer systems, so will the benefits society will derive from them.

Creating more information technology (IT) professions is proportionally related to how many new computer systems are put into use. As new computers are sold to consumers, the demand for more IT professions will rise because consumers will need these professionals to maintain, upgrade and repair their new computer systems. . More employment is also made available when new computer applications are discovered. This makes sense because new applications require new professionals that are trained to deal with that specific application. For example, when the World Wide Web was introduced, many new professions arose. Some of these professions range from website designers and server administrators to online marketers. These factors show that computers are benefiting society directly by creating new information technology professions, which is vitally important to the development of any countries labor force.

Computers were introduced into cars in the late nineteenth century, for such effects as controlling engine functions, fuel injection, and signal light timing. It is not until recently, that computers have started to play a role in helping to save peoples lives by enabling car manufacturers to create new automobile safety features. Air bags are an extremely important safety feature in an automobile. A computer is located in the steering wheel of an automobile, which is equipped with airbags and is the only device capable of signaling the airbags to deploy in the case of an accident. According to McCormick (1999), it is an estimation that “between 1990 and 1997, air bags saved about 150 lives in Canada. In the United States, the National Highway Traffic Safety Administration (NHTSA) estimates that airbags, as of September 1, 1999, have saved the lives of over 4,600 Americans involved in car crashes.” This would not be possible without computer systems. Another popular safety feature is the anti-lock braking system, or ABS. The purpose of the anti-lock braking system is to stop a vehicle from locking its tires, which has been shown to dramatically increase a drivers control in a potential crash. These safety features have proven to be beneficial to society thanks to computers, by decreasing the number of automobile accidents, and the number of fatalities involved in such accidents.

Society is dependent on rapid and reliable communications. Computers have allowed us to open ground-breaking communication methods that satisfy those dependencies. One communication method is known as electronic mail (e-mail). E-mail has become a common form of communication because it is free, reliable, and most importantly, incredibly fast. Due to the nature of e-mail, being electronic data, it relies on computers to deliver and receive messages. Another popular method of communication making rapid headway is instant messaging, or IM. According to a survey (Shiu & Lenhart, 2004) “53 million American adults use instant messaging and its appeal is especially apparent among young adults and technology enthusiasts.” Similar to e-mail, instant messaging allows many people to send textual information to each other simultaneously. This form of communication is similar to a telephone conversation, but using electronic text as a medium instead of a person’s voice. As instant messaging is based on electronic text, it is dependent on computer systems to operate because they are the only devices capable of transmitting and manipulating electronic data. Both of these new communication methods are bringing people closer together, in a global sense, and this is benefiting society.

New problems for society will continually emerge, and as a result, computers will be applied to such problems. These machines are the work horses of the future and as such, society will greatly depend on them. As stated, the three most important ways computers are benefiting society now is by creating more information technology professions, developing new automobile safety features, and opening ground-breaking communication methods. Therefore, computer systems have been shown to be a great benefit to society through these three examples and society will continue to depend on the benefits these systems provide in the future.

Save Money by Setting Up a Home Network System

January 21st, 2010

Setting up a home network can potentially save you some cash. A network allows computer users to share printers, resources, data, other hardware, and Internet access. A Network Interface Card (NIC) will help you accomplish this.

In order for a network to work the way it should you will need to have a least 2 or more computers.

Installing a network card is as easy as using it. The card gets installed directly into a freeport on a desktop, or just slide it into a free PCMIA slot for a laptop. After you have done this, you will need to install the proper software along with device drivers into your computer. The last step is to connect the router via cables.

If you are using a wireless system, your network card and router must also be wireless. Today most new computers are equipped with network cards already. This makes setting up a network even faster.

There are several manufactures of network card. Below are some of them with some details about each one.

*3 Com: Producing network cards for the enterprise market. They provide secure type network cards with encryption, remote management, and server features.

*Broadcom: This company’s network cards are usually not visible on retailers shelves because they are already installed in other companies products. Companies were you might find Broadcom network cards are Apple, Dell, Gateway, AP, IBM, Fujitsu, Micron, and NEC.

*Belkin: Presents products that can be used at home, in the car, or just on the go. One option they have is selling network cards, hubs and routers as a set.

*Intel: this is the leading company for network cards for consumers and enterprise organizations. Their products include standard Ethernet, Fast Ethernet, and Gigabit Ethernet adapters.

How to Create a Small Network for Home or Office

October 26th, 2009

Networks are a wonderful thing. They allow people to exchange information, share resources such as printer and folders, and access a common Internet connection. They used to be expensive and complicated to setup. But, no longer are networks only for large businesses. They can now be setup within minutes in a small office or home.

 

A network by definition is two or more computers connected together for the intent to share data. Therefore, each computer has to have a way to receive data and that means is through a network card whether it be wired or wireless. Nowadays, most new computers (desktop or laptop) have network cards built into them. Wireless ones you most likely will not see if already installed as in laptop computers. Wired network cards, however, have a distict plug on the back of the computer, they look like oversized phone jacks.

 

Now you might wonder, “OK, how do I connect the computers together?” Well, there has to be a point of connection. That connection is through a router. These devices serve two purposes, a hub and gateway to the Internet. Their main purpose is to take the data coming in from one computer and relay it to the receiving computer. The connections to each computer are made with Ethernet cables which are available at most electronics stores.

 

Once the computers are connected with cables to the switch, some minor configurations have to be made on each computer. Depending on whether you’re using MAC or PC, the concept is the same. Open your network connections window and open the configuration for the Ethernet network connection. Here you want to make sure that your options are set to use DHCP, which allows the computer to automatically get a network address from the router. You also want to make sure that DNS server settings are set to be automatic. The router will issue these settings as well. Repeat these steps on any other computers you wish to include in your network.

 

If you are opting to create a wireless network, review the instructions provided to you by your router manufacturer as to the installation and configuration of your computers. In general, without any additional configuration of the router, your computer should automatically find the wireless network and connect. (However, it is recommended to improve your security so that outside parties cannot access your personal network.)

 

At this point, you have created a basic network; your computers now can talk to each other giving each other potential access to files and devices. If you’ve set your router up to the Internet, at this point you should be able to browse the Internet as well from both computers.

 

To share folders and printers, one needs to setup sharing on the computer. Depending on what type of computer you are using and what version of operating system, the proceedure to setup sharing differs. However, for the most part, it is a matter of creating a “share” name for the folder or device and then connecting to that folder or device from the other computers.

 

That is how a basic network is created in a small environment. In a larger environment, the equipment is larger and generally more expensive and involved, but the same access proceedures apply.

 

SAK Information Systems, LLC has installed many small networks in homes and offices for the general purpose of accessing the Internet and sharing files. If you are interested in having a network setup, please contact us via our web site.
