RAM (Random Access Memory )

RAM is a moniker for Random Access Memory. It acts as a short-term memory much like the human brain to store a wealth of information. The RAM is accessible through the computer's brain called the CPU which stands for Central Processing Unit. RAM has the capability of being retrieved only while a computer is on. When the computer is turned off the RAM is no longer accessible. ROM chips along with BIOS (computer boot firmware) allows the RAM information to be retrievable when the computer is rebooted.

RAM size and Location on the Computer System

Most computers come equipped with 256 million bytes of RAM already on the computer. Additional RAM can be placed within the system. However, there is usually a limitation placed upon just how much RAM can be added to a computer system. RAM is not random as its name would lead one to believe. The RAM is highly controlled and the storage can be directly ascertained. There is a decisive method that RAM utilizes to make its memory available to certain areas of the computer system.

Forms for RAM

RAM is what is known as discrete microchips which means that it is separate. An additional form of RAM is modules which attach into outlets in the motherboard of the computer. A network of electrical pathways to the processor allows the connection to spark for the RAM.

Why is RAM Important

RAM serves the very important function of retrieving information that must be accessed in a quick manner. This operation is very similar to the human brain's function in retrieving necessary facts from short term memory. Open files and the utilization of applications on a computer systems requires the assistance of RAM. Users that play alot of video games with detailed graphics or keep alot of folders open while on their computer, will need the use of additional RAM. This will allow them to better access the information they need when the time comes. RAM is held onto a limited time, but it allows the information to come up quickly and without much fuss on the part of the computer user.

Tips For Selecting The Right Notebook Computer

These days it is very common to find people taking their notebook computers with them everywhere they go. Having one can be very convenient and make working on the go less of a hassle. It can be confusing though to figure out which one you should buy because the market is saturated with different brands and models of notebook computers.

Before you go out and look at notebook computers write down what your needs are. This will help you narrow down your selection. How often will you be taking the notebook computer with you? If you plan to use it often when you travel for work or for other activities you want one with a long battery life and that is very light. You also want one with a good warranty in case it gets damaged.

The size of the screen is important. Nothing is more frustrating than trying to complete work on a screen that is so small you get distracted from what you are trying to accomplish with it. Think about the different features you are going to need for your notebook computer. It doesn’t make sense to pay for features you won’t every use. Some of your options include a memory card and a disk drive.

It is very important to consider the amount of RAM you will need for your notebook computer. You definitely don’t want to be limited in the amount of work you can perform on it because you don’t have enough memory.

Once you have decided all the components of a notebook computer you need you are ready to take a look at what is available on the market that offers those items. You can compare prices as well as read consumer reviews to help you make the right purchase.

How to find Cheap Laptop

Ah yes, I want a laptop but I am not going to spend a couple of thousand dollars for one. Well guess what you don't have to. Laptop prices have come down dramatically over the past year alone and they will continue to do so as technology advances. But the trick here is to find good quality laptops that fit your needs at the cheapest prices available today.

I would say that there probably is a store near you right now that has cheap laptop computers. In fact, many stores already have them. The reason being, like any other new product, laptops were once considered the cream of the crop in the computer world which made them very expensive. However, all that has changed now. Laptops are a dime a dozen! The hand held digital assistants, Bluetooth cell phones and tablet pads are the new rage making laptop computers cheap.

Now, don't get me wrong, this does not mean that they are cheaply made. Thanks to the wonders of the technological cycle, laptop computers are decreasing in price as their capabilities rise. Of course, there are the latest and greatest monsters out there that are made for gaming or high powered multimedia applications and these babies still cost a pretty penny.

But for the average user, you can find cheap laptop computers that provide all the power you need and then some. Every major manufacturer out there, there have lower end and intermediate models that come with more than enough speed and usability.

Now here is the key to finding the right cheap computer laptop for you, and that is to figure out exactly what you need it for.

Are you going to use it mainly for surfing the web or word processing? Do you need it to work from home or mainly to save your MP3 and digital pictures?

OK, so now you have an idea of what you want to use your laptop for. Now let’s go out shopping and compare. You can visit any of the top manufacturer’s websites or visit your local store and find their low end or intermediate models that may suit your needs. The three top components of a computer you want to look for is the hard drive size, memory, and processor speeds and takes notes of each model you find on each component and model.

The hard drive, you can consider this the brain of your computer; this is where all your files, applications and folders are stored. If you plan on using your computer for MP3 and digital pictures your hard drive should be large since these files are usually very large. I personally would look at 1000 GB as minimum.

Next would be the memory, memory can be considered the thought processes of your computer. As a minimum I would look at 8 GB but if you plan on using your laptop for gaming of course this should be much larger, in the area of 1 to 2 GB. Now memory is used whenever a program or application is running. So the more memory you have the faster your computer can process the program.

And finally your processor, now your processor is just that it processes all the inner workings of how each program runs. The faster the processor is, the faster the program instructions are processed. Again if you’re looking for a laptop for gaming uses you want your processor with high speeds 2 GHz or more. For other uses you can go less.

Other parts of the computer to also consider are the ports involved that can connect your computer to your digital camera or your MP3 player for example. You also want to check that your laptop has wireless and broadband connectivity. Many cheap computer laptops today already come with this but you want to make sure or you will have to pay additional, for example, a wireless card to install in your laptop to have this capability.

How To Make Children Smart Computer

Although research on the use of computers in education plods along slowly compared to the progression of the technology itself, there are already positive correlations between children’s education and computer use. If employed effectively and within a comprehensive educational program, computers can: help a student increase critical thinking skills, allow for customization and learning based on the individual students’ interests and pre-existing knowledge, aid in memorization through interactivity, enhances collaboration among students who are not in the same geographical location, and can simulate complex or real-life tasks. In short, programs that incorporate computer use and technology for learning are many times, more effective than instruction that does not.

The use of computers for learning does not need to stop once school lets out. Creating a home “computer learning center” for your child will create an environment that encourages learning outside of the classroom. To create an educational home computer environment, you will need to do the following:

The physical computer workstation your child will need a comfortable computer desk. Because children are smaller than adults with a shorter reach, it’s important to find a desk that’s ergonomically designed to fit his/her body. We found several high-qualities, affordable options at Versa Products, Inc. (an American manufacturer or classroom tables with adjustable heights and various desktop sizes that sells direct to the public). They will also need a comfortable chair.

Buy a computer. If this isn’t a computer that will be shared by the whole family (for example to be used for financial management, online shopping, etc.), don’t spend a lot of money. The computer needs to be reasonably fast with a high speed internet connection, but it doesn’t need extra hard drive storage space or other fancy features available for exorbitant prices.

Make the computer internet-safe. Your child will need internet access for research purposes and email. The internet allows children to explore new places and learn things they wouldn’t otherwise. But the internet can also be a dangerous place for a child with the prevalence of easily accessible adult websites, chat rooms, etc. Take time block inappropriate sites, create filters, and actively monitor the history of the sites visited after your child is done with his/her session on a daily basis.

Although the computer is a tool to enhance education and exploration, too much of even a good thing can reduce its benefits. Children still need to be involved in group activities with other children and adults (in-person) as well as physical activities and non-computer play. The American Heart Association suggests limiting computer activities at home to no more than two hours per day. If those two hours are well spent doing internet research or playing educational games, that amount of time should be sufficient. Encourage your children’s learning by taking an interest in their progress on games and becoming involved in conversation about interesting topics they’ve discovered.

Computer Accessory

The spare room or a quiet corner can be a perfect place for productivity. To outfit your workspace, you might need to invest in some new hardware like a second computer, a bigger monitor or a high-quality printer. Once you've got your home computer set-up, you'll need to connect it to the Internet or network it to other computers and peripherals in the house. With a good grasp of the facts and a firm idea of your work habits, you'll be ready to make sensible choices for your home-made office.

• The Computer. Not everyone needs the same level of performance in a home office computer. You might use your computer primarily for word processing and email which requires little processing power. On the other hand, you may want more power to run database analysis, large spreadsheets or graphics applications. The type of work you do and your work load will determine whether you need a computer with a lot of brawn or just a little.

• Processor. A computer's processor or central processing Unit (CPU) is the engine that powers the device. The speed of the processor is called the clock speed which measures how fast the processor can carry out instructions. Speed is measured in MegaHertz (MHz) and is one measure of a computer's power. A typical home office Windows PC should have at minimum a 500 MHz processor. A power user would probably prefer 800 MHz or higher. If you know your computing needs are modest, and you want to save some money, an older machine with a slower processor is worth considering. When looking at an Apple Macintosh, keep in mind that you can't simply compare processor speeds with Windows machines, as the two types of computers have different system designs. Macs generally have lower processor speeds in MHz but don't let that fool you. Newer Macs like the iMac can definitely keep pace with PCs.

• Random Access Memory (RAM). When the computer is turned on, RAM is used to hold the operating system, applications and data that you're currently running. Information in RAM is rapidly available to the processor. When RAM fills up, the computer slows down because it now has to retrieve information from the slower hard drive. Imagine documents on your desk in front of you, readily at hand when you need them. But when your desktop is full, you have to file and retrieve documents elsewhere, which takes more time. The amount of RAM you need is influenced by the type of applications you use. Graphics programs like Adobe PhotoShop or Illustrator use a fair bit of memory. Word processing and spreadsheet programs use somewhat less memory. Users who like to multi-task and prefer having multiple applications running simultaneously will definitely want plenty of memory. More memory gives you a larger "workspace" and makes your computer perform faster with fewer glitches. A typical user needs at least 64 MB of RAM with 128 MB becoming the norm. In virtually all computers, you can expand the memory as you need more.

• Hard Drive. This is the computer's filing cabinet where all your applications and data are permanently stored. Most users can fit many years of productivity into a 6 to 10 GB hard drive. If you need to store a lot of information like several years of business records or image catalogues, then you may want a more spacious hard drive. Luckily, a bigger hard drive won't cost you that much extra. Alternately, you could invest in a removable storage drive.

• Expansion. It never hurts to get a system with room to grow, especially if you foresee your home office needs evolving. Find out how many RAM slots a system has and what the maximum amount of RAM is. Adding expansion cards to your system for 3D graphics or ethernet will increase the functionality of your computer. Look for a system with two or three free expansion slots and room for additional disk drives.
