A computer is an electronic device that stores, retrieves, and processes data, and can be programmed with instructions. A computer is composed of hardware and software, and can exist in a variety of sizes and configurations. Hardware is the physical equipment of a computer system, including the central processing unit (CPU), data-storage devices, terminals, printer, etc. Software is a program or set of instructions or rules that control the operation of a computer. The most obvious hardware component is the computer case. The case is where size comes into play. A bigger case allows more room for components. A bigger case is most often used for servers. For basic home computing needs, a small or mid-sized case is most common. Cases also come in many colors mainly for user preference. The most important component for a bare bones PC is the motherboard, a printed circuit board where the processing components are connected. The motherboard itself is just a piece of fiberglass. It's actually the hardware mounted on it that does all the work in the computer. The motherboard connects directly or indirectly to every other part of the computer. IT is the "heart" of your PC. It handles the CPU and all system memory. It accepts expansion devices such as sound and network cards, and modems. Without the motherboard everything is useless. The motherboard receives its power from the power supply. The power supply is the metal box usually found in a corner of the case. The power supply is visible from the back of many systems because it contains the power-cord receptacle and the cooling fan. This is what tells the PC to turn on or off. The cooling fan that is found at the power supply is used for cooling purposes. It draws cooler air into the case from the outside, expels warm air from inside, or moves air across a heatsink to cool a particular component. Another very…...

How to Build a Computer

...How to build a computer 1. Choosing a motherboard: There many different types of motherboards to choose from they all depend on: -What kind of processor you want -What size motherboard do you want to use -How many USB ports will you need. -What kind of graphics card will you be using. 2. Buying computer parts: you can order parts by mail or buy them at the store (although online is cheaper) CPU: Choosing the right brand and pin configuration to fit your motherboard/ RAM: Correct pin configuration that will match your mother board Power Supply: If the case you choose doesn't include a power supply you'll need to choose one. 300 watts is sufficient for the average computer. Video Card: choose a video card if you're not using the onboard video that comes with the motherboard. Optical Drive: CD/DVD drive and or burner Hard Drive: PATA or SATA depending on your motherboatd Operating System: There's a lot to choose from the latest is windows 7. 3. Installing the RAM and Microprocessor Caution: BEFORE this is done make sure you've relieved yourself of all sources of static electricity. Easiest way to do this is by grounding yourself. First, you'll need to unwrap the motherboard and the microprocessor chip. The chip will have one marked corner that aligns with another marked corner of its socket on the motherboard. You don't need to apply any pressure - if it's aligned correctly, it should fall into place. Once you have it in, cinch it down with the lever arm.......

Build a Speedy Windows 8 Pc with Under $500

...Although Windows 8’s controversial interface changes and obvious accommodations for mobile hardware may cause die-hard desktop users to approach the new OS with trepidation, Windows 8 offers many enhancements worth an upgrade. First and foremost, Windows 8 is streamlined to perform well on lower-end hardware than its most recent predecessors. Its minimum requirements are similar to Windows 7, but Windows 8 uses less memory, consumes less disk space, and its UI elements aren’t as graphically rich. Windows 8 also leverages most GPUs to accelerate more OS elements in hardware than does Windows 7. All of these changes in Windows 8 culminate in an operating system that simply doesn’t need high-end hardware to run well. Knowing that, we set out to build a speedy Windows 8-ready system for under $500. With such a limited budget, dedicating a significant amount of money to any single component isn’t a possibility. With the right balance though, half a grand should be plenty of cash to put together a nice Windows 8 system with minimal compromise. Choosing our components Let’s get what’s probably going to be the most controversial decision out of the way first: The heart of our sub-$500 Windows 8 system is an AMD A8-3870K APU, or Accelerated Processing Unit (basically a CPU + GPU combo). The 3870K sports a quad-core CPU running at 3.0GHz and an integrated, on-die Radeon HD 6000 series GPU. We chose this APU for a few reasons. First off, even though Intel’s desktop processors......

How to Build a Powerful Network

...Article – The real way to build a social network Reid Hoffman and Ben Casnocha This article is from the February 6, 2012 issue of Fortune. “Networking” is a very common word now-a-days. It is not only about what you know, but it is also about who you know. Reid Hoffman is a partner at Greylock and founder and executive chairman at LinkedIn Ben Casnocha is an award-winning entrepreneur and author. The article talks about building a social network. It tells about building a relationship with others requires two important abilities. First, one should be able to see the world from other perspective. Second, one should be able to collaborate with other by helping them and not by thinking what he/she would get in return. Keith Ferrazzi, author, New York Times #1 bestsellers, Who's Got Your Back and Never Eat Alone quotes: “The currency of real networking is not greed but generosity.” The article then goes on and describe the ways in which one can diversify and strength his/her network. The author describes that the best way to increase the efficiency of your network is by strengthening your relationship with people who you already have in your network. The article also talks about the weak ties and how they can help you increase the effectiveness of your network. Weak ties are normally outside one’s inner circle and hence have a greater probability to give new information that your close relationship might not. The article then goes on to talk about the three degree of......

How to Build a House

...The proper way to build a house By Jeremiah Archambault Homes today is what is needed in everyone’s existence, and range from being as simple as a tent or shelter of branches and leaves, and all the way up to a multi-story palace with several bedroom and bathrooms to your basic single story home. Whatever the structure may be it provides shelter and simplifies one’s life. Here are the proper steps involved to successfully construct a home. Selecting a location for your house has several items to consider before the construction begins. You should consider the climate, ground stability, availability of utilities, community infrastructure, and available building materials. When looking at the climate of the site one needs to make sure they are not in a flood plain, and also taking in to consideration of the temperature that the house will be built in whether it is intense heat to frigid cold. Ground stability is making sure that the soil is suitable. If the soil is mucky, shifting sand or other unstable earth will likely fall over a short period of time unless they are not built on special foundations or pilings. The availability of utilities is also important if you intend to have power, potable water, telephone and other conveniences, make sure these utility providers offer them at the location. The community infrastructure is also important to look at. Make sure good quality schools are available. Check to see if you are in a police jurisdiction to protect you from......

Cheap Pc Build

...For my cheap pc project I came in at just under $220 for the pc itself and a total of just under $320 including monitor and printer. Finding the cheapest parts I could while retaining some form of plausibility was a little difficult at first but once I found the right sites it became pretty simple. The entire pc was purchased from newegg.com. For the mother board I selected was a biostar AM1ML AM1. For the price this motherboard is listed it’s a good piece of equipment. While it isn’t going to run some of the programs and games I use on my home system, it should be more then alright for your average internet user. The same goes for the CPU, running only one core at 2.8 GHz, this chip doesn’t exactly scream performance. Perfect for Facebook games, not so much for PC gaming. For the ram in the computer I went with two sticks of 1GB ddr3 memory. Two gigs total should be plenty of ram to run the operating system and internet browser. For the disk drives I went with an Asus DVD drive, non-rewritable, and a Western Digital 250GB hard drive, more than enough to keep the casual computer user happy. The case I selected came with a preinstalled PSU, at 480 watts of power. Without the need for extra cards to run the computer 480 watts would actually be a little overkill for this system, but better to have more then not enough, plus it came with the case for a good price on both. Inexpensive keyboard, mouse, and USB pc speakers finish out the hardware on my PC. At very least, in...

How to Assemble a Pc

...How to Assemble a PC In the first place one must make sure that they have all the proper tools required to build the PC. Basic tools that will be needed are: Phillips-head screwdrivers, needle nose pliers, and most importantly an anti-static wrist strap. The ant-static wrist strap is one of the most important tools that will be used because a small static shock that you will barely feel, to the computer it can cause a lot of problems as to even ruining the computer or parts of it. Next the assembly of the motherboard will be required. The motherboard is often sold with all the components in exception to the CPU. Usually good motherboards to use for a computer would be Inter G31, GMA3100, or AMD 780. The CPU must then be placed on the socket of the motherboard (make sure that the CPU is installed properly as it could short-circuit and damage the motherboard). Installing the CPU cooler would be the next step. While installing the CPU cooler make sure to use thermal paste. The installation of the RAM modules would be the next step. The RAM modules would go on the corresponding slots; the motherboard usually has 2 or 3 slots for RAM modules. The power supply should be mounted to the case and connect all the connections to the drives and motherboard. The motherboard back plate should be attached to the case and it should coincide with the motherboard once it’s placed onto the case (which is the next step). Next the hard drive should be installed.

Whether swimming or surfing, playing volleyball or snoozing in the sand, a visit to the beach means fun. Making sand castles is a project for beachgoers of all ages. Some castles are very elaborate while others are plain. “Why spend money on clay when you can use beach sand for free?” (How to Build a Sand Castle) Move this quote into a supporting paragraph. Quotes cannot be inserted in the introductory – or concluding – paragraphs. Remember your thesis statement must be in your own words, too. Is this meant to be your thesis? Be sure to create a sentence in your own words which encompasses the WHOLE main idea/purpose of your paper. The only equipment needed in the process of creating a sand castle is a twelve inch deep bucket, a small plastic shovel, carving tools, and an abundance of moist sand.
