Choosing a Computer System
When considering the purchase of a system there are several components involved and those components are software, hardware, data, procedures and people. (Kroenke, 2008, pg.5) Also when purchasing a new computer system it can be extremely unnerving and costly. When thinking of the hardware of a computer system one would look for the following components: the size of the monitor, the CPU type and/or speed and the warranty that generally is offered with a new system.
In terms of a computer monitor, it is the most important part of a computer because it is the part that we rely on and use the most. There are several types and sizes of monitors that you can use with a computer system, a CRT or a flat panel monitor. The CRT (cathode ray tube) is the larger monitor and it generally costs less than a flat panel monitor.
The type and speed of the computers CPU varies. The CPU speed in a desktop is much faster than the speed of a CPU in a laptop. Over the past few years costs have been significantly lowered in regard to CPU’s in laptops and CPU’s in desktops. These cost have almost balanced themselves and the speeds have also being the same.
Warranties on a computer system are often expensive. Most computer buyers would want a warranty in case the hardware breaks or becomes damaged. Getting a warranty on a computer may seem expensive in the beginning, but in the event sometimes breaks down one is covered at no cost.
The software of a computer is the programs of that computer. There are many programs that computers can and will use depending upon the tasks that one wants to perform. (i.e. Microsoft PowerPoint) In terms of costs the more software that a new computer use has the higher their software costs will be. Many new computers come with certain programs already installed, any additional needed programs will be at additional cost to the consumer. In the workplace computers often need licenses to run programs throughout the office. Licenses can be costly depending on the total number needed and how often the licenses will need to be renewed.
Databases are what most companies use to collect and store their data.
PC industry is affected by two opposite forces: technological advance that pushes the industry forward and the industry sensitivity to economical stagnation (if the economical situation is bad customers won't upgrade their computers).
5. Although the lines between the different computer classifications have blurred over the years, thanks to higher quality personal computers (PCs), mainframe computers still require their own classification. Mainframes have similar speeds to personal computers; however, they
Financial resources are of the utmost importance as this will be needed to purchase any software or hardware required in order for the newly implemented system to perform as proposed.
Softwares are instructions, commands, or data that direct the operation of computer systems. Hardware is the physical aspect of computers, telecommunications, and other devices. Hardware such as electronic circuitry and other components of a computer use software or programs to make technology do things. Hardware is permanent and not flexible, while software or programming can easily be varied and modified. You can put an entirely new program in the hardware and make it create an entirely new experience for the user. People can change the modular configurations that most computers come with by adding new adapters or cards that extend the computer's capabilities.
“Supply manager Joe Smith was considering the purchase of 1,000 desktop Personal Computers (PC’s) for his organization.
Historically the personal computer (PC) industry has sold its products at reasonably high prices yet garnered only small profit margins. One reason for this is the high competition in the PC industry which led to competitive pricing among producers. Analyzing the competitive environment of the PC industry, it is evident that there is very little barrier to entry in this market. PC's have very low physical uniqueness and are made of standard components that require very little expertise to assemble.
Derene, Glenne. (2009). Mac vs. PC: The Ultimate Lab Test for New Desktops & Laptops.
There are a lot of things to consider when choosing to invest in something such as a computer. Things like size, colour, and company name are all things one might consider. A major component in choosing which computer to buy is also price. People will want to get the best quality laptop for the least amount of money they have to invest in it. When a customer buys a computer, they expect that they are getting the best deal from their provider. However, some companies may choose to sell the computers for a higher price than they need to be. By not revealing the actual price the computer is supposed to be sold at, the company will lose customers, the customers will feel like they are being scammed, and the company managers will end up being called selfish and
Building a computer can be a useful skill in today's world. It allows you to
The monitor is likely the most important part of the computer. Without it, you would have no idea what you were doing. Imagine trying to write a term paper, or surf the Internet without one. It would be impossible. While the technology powering the displays doesn’t change as fast as it does for other parts of the computer, there are advances which provide consumers with many choices for displays. Today, the most popular displays come in two types, Cathode Ray Tubes (CRTs) and Liquid Crystal Displays (LCDs). CRTs have been around longer, and are the most common due to the fact that they are cheaper. However the convenient size of LCDs along with falling prices has made them a popular choice as of late. This paper will examine the similarities and differences of the two, and try to determine if one is better than the other.
The computer processor is the brain of the system. Our client requires a heavy punch, multi tasking brain. Due to his low income and student status, he does not have a large budget to put towards his computer. The AMD AthlonXP 1900 was chosen because of it's low cost and it's higher performance rating than that of the higher priced equivalent Pentium 4. The AMD AthlonXP 1900's speed is 1.6GHz. This means 1600Hz, which is a very fast processor. Amazingly, the clock speed of this processor is faster, albeit barely, than the Pentium 4 2.0GHz processor, and is much cheaper as well. This is important, as, for less cash, our student can afford a better processor.
Processor speeds are measured in megahertz (MHz) and now come in speeds of up to 1000 MHz (1 GHz), which is very fast. This is almost ten times faster than the speed of most home computers, which average from 133 MHz to 166 MHz. Intel and AMD have been in a race to break the 1 GHz speed barrier, and the number of megahertz in the newest processors is not as significant as it was in earlier processors. For example, the difference between a 133 MHz processor and a 166 MHz processor is
A computer is a device which is used for several applications; business, gaming, or school. It’s important for people to know how computers work because in this day and age, operating a computer is an everyday task. This complex electrical device utilizes several parts inside of it to keep itself cool, conduct the proper tasks, and maintain stability. These devices can be found several places whether it be on the job, in one’s room, or on a school campus. Computers are essential for everyday use in order to complete what is required. What each component is and its function will be described.
We often dream of owning the best computers in the world. However, various options from the wide range of manufacturers tend to make it difficult to do a selection. Therefore, picking a reliable model that is stupendous is inevitable; a computer that even after four years, it will still be outstanding. Knowing the chances of its success is fundamental. This means that a good machine should break less often. Additionally, a company that has a great technical support, which helps a computer owner to receive timely and reliable customer support services. What is ignored are the outliers. There are companies that have had awful record of accomplishment of crappy and extremely expensive computers. One must ensure they purchase from established and genuine dealers.
The computer has progressed in many ways, but the most important improvement is the speed and operating capabilities. It was only around 6 years ago when a 386 DX2 processor was the fastest and most powerful CPU in the market. This processor could do a plethora of small tasks and still not be working to hard. Around 2-3 years ago, the Pentium came out, paving the way for new and faster computers. Intel was the most proficient in this area and came out with a range of processors from 66 MHz-166 Mhz. These processors are also now starting to become obsolete. Todays computers come equipped with 400-600 Mhz processors that can multi-task at an alarming rate. Intel has just started the release phase of it’s new Pentium III-800MHz processor. Glenn Henry is
