Types of RAM
Right now DDR SDRAM is the most popular memory module. DDR stands for Double Data Rate, which means that the memory can be accessed twice per clock-cycle. SDRAM, the acronym for Synchronous Data Random Access Memory, has been the standard for memory modules for nearly a decade.
To add memory to your computer, you must install modules with the correct contact layout. Before purchasing new memory, you must know which type your motherboard will accept. The most common form factors are 168 pin, 184 pin and 200 pin.
You'll also need to know whether there are slots available on your motherboard. If all the slots are already in use, you'll have to replace 1 or all of the current modules with higher capacity ones. If there is at least 1 free slot, you can simply buy a new memory module and insert it in the empty slot.
A word of caution: whereas some motherboards can accept either SDRAM or DDR SDRAM, the 2 types cannot be mixed. You must decide on 1 or the other. Check the motherboard manual first to determine which kind of memory your computer requires.
And finally, when you are ready to install your brand new memory module, make sure of 2 things: the power is off (for your safety) and you are electrically grounded (for your computer's safety).

Basics of Computer Memory --part 2
Adding more memory is one of the best ways to maximize computer performance. If you compare 2 identical computer systems, the one with the most memory will over-all be the faster. More RAM allows the computer to place more program instructions into memory, relying less on the slower hard drive.
Think of 512 Megabytes (MB) as the base standard for a modern computer. With that you can multi-task (run several applications concurrently). For instance, you can check email and download MP3s, without noticeable sluggishness.
Some applications, however, are more memory-hungry than others. Graphics programs, for example, are notoriously greedy. Memory needs are further exagerated by the operating system used. Microsoft Windows is far more demanding than, say, Linux. Currently, most PCs use Windows, though.
Should you notice your computer slowing down, consider adding more memory. Before committing to that option, however, try de-fragmenting your hard drive with a utility (program) designed for that sole purpose. A fragmented hard drive is a common cause of stalled computer performance.

Basics of Computer Memory
Computer memory is called Random Access Memory (RAM). The information stored in RAM can be accessed randomly, rather than sequentially. This means that data can be found in any location at the same rate of speed. Other storage media, such as CD-Rom and hard drives, must wait while the drive spins to the correct location before the data can be accessed.
Computer memory is simply a storage area for the program code and the data that program uses. Computer programs use RAM to write and retrieve information, allowing for fast data retrieval and manipulation.

Components of a Home Network -- Print Server
Just like you can buy a device to allow you to share a hard drive, you can do the same with a printer. A print server connects directly to your printer. Your printer is then shared to all of your computers on the network. This is convent because you do not need to leave the printer hooked to a computer, which must be turned on to print.
Components of a Home Network -- Network Attached Storage (NAS)
A network attached storage device is s device that allows a hard drive to be shared across the network. This hard drive is NOT attached to any of your computers. It is simply made available by the NAS. This can be a convent way to add a hard drive that can be accessed by several computers on your network. The other common way to add a network hard drive is to simply share a folder on one of your computers. However, with the NAS, you do not need to keep one of your computers on at all times.
There are two types of NAS commonly available. The first type comes with a build in hard drive. The second accepts a USB or Firewire external hard drive. The advantage to using a USB or Firewire hard drive is that you can upgrade the hard drive if it ever were to become too small.

Components of a Home Network -- Firewall
A firewall controls traffic flow between your network and the Internet. A firewall can be either hardware or software. Windows XP SP2 or higher includes a software firewall. A hardware firewall is included with most routers.
A firewall is a very good idea. It can protect you from inbound virus attempts. By inbound virus attempt I mean other computers that will connect to your computer and attempt to infect your computer. You do not want to run a computer directly connected to the Internet, without a firewall. There are just too many other computers out there that can connect and infect you without you even noticing.

Components of a Home Network -- Router
A router is a device that has several Ethernet ports on the back of the device. One of the connectors will be labeled WAN. You should connect the WAN port to the Ethernet connection on a broadband source, such as a cable or DSL modem. The other ports on the router can be connected other computers or switches/hubs that will share the WAN connection.
Routers allow you to share your broadband connection with multiple computers in your house. Rather than connecting your computer directly into your cable or DSL modem you connect the router to the cable or DSL modem. Now any computer that you connect to the router will have access to the Internet.
If you run out of ports on your router you can always connect an additional switch to the router. To connect a switch to a router simply connect the switch’s "uplink" port to one of the routers Ethernet ports. Of course, don’t connect to the router’s WAN port. The WAN port should only be connected to something such as a cable or DSL router.
Some routers come with additional features installed. Most routers also include a firewall. Firewalls are discussed in the next section. Some routers will also include a wireless access point (WAP). The WAP allows you to use wireless devices, such as wireless laptops, with the Internet.

Components of a Home Network -- Switch
A switch is a device that has several Ethernet ports on the back of the device. One of these ports will likely be labeled “Uplink”. This port allows you to connect multiple switches together, if you run out of ports on your switch. If you do not have an uplink port on your switch, the switch can not be easily extended if you run out of ports.
A switch serves the same function as a hub. It allows you to connect multiple computers together, so that they can exchange packets. However, a switch is much more efficient than a hub. A switch will only send Ethernet packets to the computer that the packet was intended for. Because of this you should always use a switch in place of a hub.

Components of a Home Network -- HUB
A hub is a device that has several Ethernet ports on the back of the device. One of these ports will likely be labeled “Uplink”. This port allows you to connect multiple hubs together, if you run out of ports on your hub. If you do not have an uplink port on your hub, the hub can not be easily extended if you run out of ports.
A hub is a device that attaches multiple computers on an Ethernet network. If you have a number different computers that you want to connect together, you could connect each to the hub. Any packet that is sent out by any computer on the network will immediately be transmitted to the other computers. Each computer will determine if the packet was really intended for it, and filter out packets that were intended for other computers.
You really should not use a hub in a modern home network. You should always use a switch in place of a hub. Switches will be discussed in the next section

Components of a Home Network
Home networks are becoming more common. People want to be able to share a single broadband Internet connection to several computers in the house. There are many different devices that you can use to make up your home network. If you have never heard network terminology device names like router, hub, etc may seem confusing.
The purpose of most of these devices are to control how the network passes around information. This information is sent in the form of "packets". I will refer to the term packet several times in this article. It simply means the data that the network is transporting. I will now explain the purpose of the major components of a home network.

Tips for Buying a Computer (Part 3)
Most computers will come installed with software. Find what software the PC will come with and work out if this is all you need.
Basic word processing, spreadsheet and email/organizer software is adequate for most people and the ability to access the internet will require a modem installed as well.
If you are worried about learning to use your computer, don't be. There are tutorials within Windows XP to help get you started, and "wizards" are easy to use, step by step programs built into Windows that will help you learn a lot too.
Plus, once you get hooked up and online with your own computer, you will have access to millions of sites ready and willing to help you learn all about your new desktop PC, the software you have, and even learn how to do things you never imagined!

Tips for Buying a Computer (Part 2)
Of course notebook computers are really great if you want to take advantage of the portability that they offer, although you really need to weigh this against the cost -- as laptops are still much more expensive than your average PC with the same functionality.
You need to determine what capabilities you want your computer to have – the size of the hard drive, the memory and the types of cards – video and audio – that it comes with.
For a standard home or basic office use you should be adequately served by 256Mb of RAM memory with a 80Gb hard drive for storage.
Two other things to consider are that you will need a monitor and software.
For a monitor, try for a 17 inch so that you don’t have to squint to see what is on your screen. Flat panel displays are great for saving space too and the clarity of the displays now are quite impressive.

Tips for Buying a Computer
The first question you need to ask yourself is why you need a computer and for what purpose you will use it:
* Surfing the Internet
* Sending and receiving e-mail
* Word Processing
* Spreadsheet and Money management
* Listening and recording music
* Storing and manipulating images
* Playing games
When you are certain that you really need a computer then you need to consider what computer to purchase.
The most common type of computer is the PC. Fewer and fewer people these days use Macintoshes and while Apple still makes them they are used primarily for graphics work at the high end multimedia level.
For home or office use you may be far better purchasing a desktop PC with pre-installed software. And PC prices are on the way down.

Protect Yourself From Computer Viruses -- Part 2
If you use floppy disks or USB drives on public computers like your school computer lab, Kinko’s, or even digital photo printing store make sure you scan them for viruses. Public computers are notorious for not being up to date and properly protected.
Be wary of email attachments. Treat any email attachment as potentially dangerous. Never open attachments from people you weren’t expecting. Also be careful of attachments from people you know but weren’t expecting. Many computer viruses replicate themselves by reading the contacts from an infected computer.
Use text email if possible. While HTML email is prettier and allows you more control over formatting it also can carry computer viruses. If you use text based email the only way to get a virus is by opening an attachment.
Use downloaded freeware and shareware files or software with caution. Try to download them from popular reputable sources that scan the programs before they are uploaded. To make sure you are safe scan the program before you install it on your computer.
Be wary of links in IM or instant messaging software. Don’t accept invitations from people you don’t know and never click a link from someone you don’t trust, they can easily redirect you to another website that will try to install a virus on your computer system.

Protect Yourself From Computer Viruses
Use a high quality anti-virus program. There are many different anti-virus computers programs on the market some of them are better than others. Look to reputable computer magazines or websites for ratings to help you find the one that matches your needs.
Always use your anti-virus software. Make sure your anti-virus software is always turned on and scanning, incoming and outgoing email messages, and any software programs you run.
Keep your antivirus programs up to date. Most programs come with a yearly subscription make sure you take advantage of the updates. More advanced programs allow you to schedule updates or full system scans for “off hours” like 2AM when you aren’t likely to be using your computer.
Keep your computer up to date. From time to time operating systems fall victim to security holes or issue updates. Make sure you check periodically to make sure you are running stable up to date versions of your software.
Backup your data regularly. Most windows computer users keep their documents in the “My documents” folder. This makes it easy to back up all of your important documents. Make weekly or monthly copies to CD or USB drives.

Introduction To Spyware
Spyware is the most troublesome software to appear on the
Internet in recent times. When spyware infects a computer
system, it may be relatively harmless or it may be
devastating.
Spyware like coolwebsearch and new.net are capable of
paralyzing a computer system. Laws to regulate spyware are
pending in many states and may take years to enforce.
What Is Spyware?
Spyware is any software that collects information about
computer usage and/or the computer user. It is installed on
one computer and sends information to another computer.
Some spywares like the Weather Bug, Bear Share and Kazaa
are knowingly downloaded and installed by users. Other
spyware is installed without the knowledge or permission of
the user.

A Guide To Basic Computer Terminology (contd) part 2
Mouse: The mouse is another input device that makes getting around in your computer easier. It is a handheld object that is good for doing tasks such as moving and pointing to objects on the screen, and can replace the function and control keys of the keyboard. (If you need a lesson on how the mouse works and how to use it click here for a tutorial.)
Printer: A printer is an essential part of the computer if you want a hard copy of your work. There are four types of printers on the market: dot matrix, inkjet, bubble jet and laser. The dot matrix is the most basic. Most inkjets and bubble jets can print color and graphics, and a laser printer offers the best resolution at the highest speed.
RAM:Computers save data in two ways: on the hard drive and in random access memory or internal memory. New computer buyers should look for models with at least 16 MBs of RAM (or more, depending on what types of programs you'll be running). Make sure that the computer can be upgraded.
Scanner:A scanner is a useful accessory to have if you are working with lots of artwork or photos. This device can copy written documents, pictures or photographs directly into your computer. There are three types of scanners: handheld, hopper-feed and flatbed.
Sound Card: This device allows your computer to reproduce music, sounds and voices. Make sure you have a sound card if you're planning to play multimedia games.
Video Card: The video card is the part of the computer that sends the images to the monitor.

CPU: The CPU, or central processing unit, is the brains of the computer. Most new Windows based programs use a Pentium processor or a AMD Athlon XP. New Macs use a different type of CPU called Power PC.
Disk Drive:Virtually all computers come with a disk drive that can read and save information on portable diskettes, also called floppy disks. You can use floppy disks to save information or to load new software onto your computer.
Hard Drive: The hard drive is also called the hard disk. You'll probably never see it because it is nestled inside your computer. It's the computer's electronic filling cabinet, and it stores the computer's operating system, files, programs and documents.
Keyboard: Just like a typewriter keyboard, this device is the primary way of inputting data into the computer programs.
Megahertz (MHz): This is the clock speed of the microprocessor. The higher the number, the quicker the information is processed. MHz relates to how many millions of instructions can be processed per second.
Memory:This is the circuitry or device that holds information in an electrical or magnetic form. There is read-only memory (ROM), which is information primarily stored on a disk, and random-access memory (RAM), which is chip-based storage inside the computer. Memory is typically measured in megabytes (MBs).

Ram? Mouse? One is an animal and one is a rodent right? Ram...that is the zodiac sign for Aries... If this is what these words mean to you than you can surely use this quick glossary of computer terminology. It would be a good idea to read through them before purchasing a computer because these are things you should know about first. If you already have a computer then these computer terms can help you know what to do if your new computer equipment is unfamiliar. Also, this computer terminology can help you if you have to call in for technical help.
Okay lets go!
Cache: Cache is another type of memory kindred to RAM. The computer uses cache to quickly move data between the RAM and the CPU.
CD-ROM Drive: Most new computers now come with a CD-ROM drive as standard equipment. A CD-ROM drive reads data from a disc. These CDs look like a music CD, but hold data instead of music. CD-ROMs also contain games, dictionaries, recipe files, and lots of other things that you can load onto your computer

Data-Recovery (contd)
There are many more ways in which you can lose all of the personal data that is stored on your computer. You don’t even have to have the programs running to lose it. Nevertheless, many people mistakenly believe this will not happen to them and therefore do not do anything to prevent this total loss. Data recovery is necessary for this not to happen. The strange thing is, it takes only minutes to install and use and it virtually and it takes care of itself. It is not overly costly either. So, why don’t more people use data recovery? They just don’t realize its importance. And that is one mistake we don’t want to make. Data recovery is a need all computer users have.
Data-Recovery
Data recovery is something we hope that we will never need. Whether you simply make the mistake of deleting important software or you lose it all in a computer crash, that valuable asset of information may seem like it is lost forever. But, if you have complete and quality data-recovery software on your computer or through your system, you can be confident that it has a backup and it is there even though these things will happen to you. This can be so important when it comes to safeguarding your business or your personal information.
What people do not realize is that there are a number of ways that things can go wrong on their computers. Whether you are responsible for the computers of a large corporation, a small business or even just your own personal computer, having a way to restore information when things go wrong is quite important. Here are some things that could happen to you, well, anytime, even right now. Your computer could be running slowly or be loaded with powerful spyware that can destroy files, transmit personal data or, even worse, cause the computer to crash. All of a sudden, it’s gone. Or, you could be working along nicely without a care in the world and bam! A power surge, an electric storm or something else electrical happens and it’s all gone.

#3 -- Stop Popups!
Never click inside the window of a popup. Instead, close it by clicking on the X in the upper right corner. Many people are fooled into installing spyware applications by popups that promise to clean their system. If you receive a message saying it can help, assume it’s spyware and don’t click!

#2 -- Should You Leave Your Computer Running?
One question we hear frequently is, "Should I leave my desktop computer on or turn it off?"
There are 2 schools of thought…
Turning it on and off numerous times during the day subjects the microcircuits to flexing and fatigue due to change in temperatures. Over time this could lead to a break in the circuitry and result in system failure.
Leaving the computer on all the time puts excess wear on the mechanical components (the hard drive spindle motor and cooling fans).
Best compromise. First user in the morning turns it on; last user turns it off.
We leave our desktops on all the time allowing for scheduled utility tasks to run during overnight hours. We also restart the systems (to flush the RAM and reset the operating system) on a regular basis and routinely remove the case covers to clean out any dust that may have accumulated, especially around the fans and screens.

3 Summer Computer Tips
#1 – Summer Computer Travel
Holiday travelers should be on alert when arriving home from long weekends, such as the Fourth of July, a popular time for computer viruses to spread.
Most computer users have a tendency to turn off their computers when away on trips, which means you’re not getting newly-released anti-virus patches or anti-spyware updates; the two most common areas that cause computers problems. We recommend you update anti-virus and anti-spyware scans before opening e-mail or going online after an extended absence.
We consistently see an increase in calls for virus related problems immediately following long weekends. Avoid the problems altogether by updating your security software before using your computer. For a free listing of viruses, spyware threats and trends,

Notebook or Desktop Computer (contd)
Screen Resolution
Computer monitors -- the bulky ones, anyway -- can be set at different resolutions. In other words, you can change the fineness of the image on the screen. The range is typically 640x480 -- that is 640 pixel across and 480 pixels up and down -- to 800x600, 1024x768, or even higher. At 640x480, the icons and such appear quite large; at 1024x768, they are substantially smaller. The most common resolutions today for desktop computers are 800x600 and 1024x768.
Something They Don't Tell You
Laptop displays, on the other hand, have a fixed, or native, resolution. You can change the setting, but then the images and text don't look good. While people tend to think that bigger numbers are better, a higher screen resolution may not work as well for you. It may make everything too small to see comfortably.
Remember, the laptop's screen is smaller that a desktop's. While a typical desktop computer screen is 17" or so a laptop's is usually in the range of 12" to 15." That is a big difference. Make sure you can see everything clearly before choosing a high-resolution laptop

Be Mindful of Ergonomics
Ergonomics is the science of designing and arranging things so that people can interact with them more comfortably and safely. The basic ergonomic principals for computer use tell us that, 1) the keyboard should be as close to your lap level as possible (assuming you touch-type), 2) the monitor should be about arm's length in front of you, and 3) the top of the monitor should be at about your eye level. Try achieving that with a laptop computer! Two words: im-possible.
It is obvious then, that a desktop computer is much better ergonomically than a laptop is. For prolonged use, especially, you're much better off with a desktop computer.
And Don't Forget Usability
Another aspect of ergonomics is usability. Because of size constraints, laptops also are lower on the usability scale than desktop PCs are. For one thing, laptop keyboards lack the separate groupings of the different sets of keys with space between them. For another, there are fewer keys on a laptop's keyboard, so some of them have to perform double duty. On a standard keyboard, you don't have to deal with that.

Notebook or Desktop Computer -- Which Should You Choose?
Portable computers cost more, so unless you really have the need for one, you get a lot more computer for your money with a regular desktop PC. The main thing is portability. If you need a portable computer, get a laptop. ("Laptop," "portable," and "notebook" all refer to the same thing, by the way). Otherwise, a desktop computer is a better buy, and better ergonomically.
The Price Difference
You might wonder why laptops cost more than desktop computers with comparable features and power. That is largely because it is more expensive to manufacture laptops and their parts. For portable computer components, factors such as compactness, the amount of heat they generate, their weight, and power consumption are more important than they are for desktops. Those factors add to their manufacturing costs.
Space Requirements
While laptops are certainly compact, a desktop computer with a flat panel monitor can take up almost as little space. While called a "desktop" computer, the computer itself is most often kept on the floor. That leaves just the monitor, keyboard and mouse on the desk, which is really very similar in footprint to a notebook computer.
A great way to further reduce the space taken up on the desktop computer is get a keyboard drawer to hold the keyboard and mouse. That way, they slide out of the way under the top of the desk when they aren't needed.
