Although laptop and notebook computers are less expandable than desktops, you can still upgrade their performance so they can run today's demanding software. A laptop computer memory upgrade is an inexpensive and easy option that will provide a huge speed increase.
Can Your Laptop Upgrade?
The first step is to verify that your computer can accept more laptop computer memory. While most laptops can, your computer may already be running at full capacity. You may have already asked for the maximum amount of memory when you originally purchased it. If that's the case, you'll have to find other ways to improve the performance of the computer.
Check the manual to see how much laptop computer memory your machine can take. If you either didn't get a manual or don't still have it, look on the hard drive. Many laptops have a copy of the manual in My Documents or in a dedicated directory on the C: drive. You can also check the manufacturer's website either for a downloadable copy of the manual or for system specifications.
Once you know the capacity, check how much memory is installed. The easiest way is to right click on My Computer and select properties. You will see the amount of computer memory (RAM) already installed.
Installing The Memory
If you've installed memory into a desktop computer, installing laptop computer memory is pretty similar. In fact it's easier because the memory is more accessible than trying to reach down between the power supply and the video card without touching anything.
Unplug the laptop before working on it but also remove the battery. There's no reason to take chances of an accidental shock that could injure you or damage components. Put the laptop on its face and look on the underside for a panel covering the memory cavity. Unscrew it and lift it away to reveal the existing memory.
Locate an empty memory slot. There will probably be two slots and one will already be occupied. Cut open the anti-static bag that carries the new memory and touch a metal object to discharge any static electricity. Normally it's best to touch the computer case, but replacing laptop computer memory generally doesn't expose any metal part of the case.
If you've never installed laptop computer memory it can seem a little awkward. You slip the memory stick into the slot at an angle then push down on it until it snaps flat. Don't force the insertion. If it won't go in, take a look to be sure you aren't putting it in backward. Memory for computers is designed to go in only one way.
Once you are done, screw the cover plate back on, replace the battery, plug the computer in and turn it on. Double check My Computer as you did before to ensure that Windows sees the new memory. As you can see, this is a simple upgrade that adds years to a laptop's useful life.
It's safe to say that most modern businesses are highly dependent on the technology that facilitates their processes. In most cases, losing or accidentally erasing data can be extremely detrimental to a company's operations. In some cases, business will come to a complete standstill if data is lost. For this reason, data recovery strategies have become a necessity. Some businesses choose to create a disaster recovery site in-house. With this strategy, IT executives can choose to outsource disaster recovery or to train in-house staff to perform it. Case studies have shown that outsourced recovery service (whether with an in-house site or an off-site facility) is less likely to fail than outsourced disaster recovery service.
Your Company's Needs
There are several different factors to take into consideration when evaluating potential disaster recovery vendors. First, an introspective approach should be taken. Companies seeking disaster recovery services should review their business functions and their reliance on technology and data. This step will help define the organization's needs, especially in terms of timing and opportunity cost. In other words, a company must determine how much downtime they can afford and how much that downtime will cost. Since larger amounts will be paid to an outsourced provider for faster recovery, you must weigh the cost of downtime in relation to the cost of more expedient recovery.
Your Vendor's Capabilities
Another consideration for IT executives considering disaster recovery options is the breadth and depth of the services provided by any given vendor. Companies must determine whether they need a fuller range of services, such as data center space or workspace for employees. Businesses must also evaluate vendors' technical strengths in relation to the specific functions and processes that their business operations rely on. In speaking with representatives of a disaster recovery service provider, principles must feel confident that the vendor not only understands their business' needs, but that the vendor has the resources necessary to support the customer's core technologies.
Data Center Location & Layout
When choosing a data recovery site, a company must consider the location of the data center carefully. Choosing a site that is too close to it's own data center can mean that the data recovery site is also affected by whatever storm or power outage is causing problems. A site that is too distant can be difficult to get to in a timely way (or it may take more time for a representative from the data recovery service to arrive at your location). Layout of the data center is also important. Consider where the equipment is located in relation to windows, doors, and possible sources of moisture or heat. The best-case scenario is a hardened data center with excellent security, backup power, and communication links.
Experience and Continuity
When choosing any type of vendor, experience and general customer satisfaction must be taken into account. How long has the data recovery service provider been providing such services? How would present and past customers who have purchased this service from them rate the service? Is the company financially stable enough to have the resources necessary to support every type of emergency? What successes and failures has the service provider been through over the past few years?
Choosing a data recovery service and site is not to be taken lightly. In the event of an emergency that causes data loss, your company needs the peace of mind that business functions and processes can be restored quickly and fully. In order to achieve that peace of mind, IT managers need to have complete confidence in their disaster recovery plan. Choosing the right provider and facility can provide that confidence.
In today's world, most people own at least one computer at which they spend a great deal of personal and working time. By doing so, they are generating a lot of important data and using often expensive programs to perform various tasks. So what happens when the computer hard drive, the part of the computer that stores all this data and the programs, decides to "crash" or quit working? That can be very devastating to the computer owner when it happens, as you may have guessed already.
What precautions can a computer user take to avoid losing all of their important data and software in the off-chance that their system goes down? Computer professionals recommend that users regularly back up their data to an outside source. This can be to a portable digital device like a disk, a flash drive or a website designed specially for storing data securely. Likewise, software can be backed up as well and here are some suggestions on how to best go about doing this periodically.
Keep a spare hard-drive
Some computers, including laptops, come with removable hard drives that can be exchanged with other removable hard drives. This can be especially convenient when you have to travel away from your business computer and need to carry with you all of your computer contents. But this can also be very useful when you back up your computer software and other large files that will probably be too large for a simple disk file or flash drive. Using the default windows backup process that your computer came with, you can install backups onto the removable hard drive and then keep it in a safe place just in case you ever need to restore these files to your exiting or another computer.
Utilize a backup software
There are several reliable software products out there on the market that can make a copy of any software applications you are using on your computer, plus any files and store them securely on an outside and secure, web-based server. The software essentially makes a carbon copy of your entire hard drive that can be accessed if needed. This is less expensive than buying an actual backup hard drive as well. This type of software is often referred to as "PC Recovery" software. Be sure to review the different types available before settling on one that will work for you.
If you are using a computer at your employers, chances are it is already connected to a central server. Any programs you download will also be copied to that server, including any files or work you process on your computer. In the case of a system crash, the IT administrators for your company can pull up your data and software and restore it to your new or repaired computer easily.
It is always a good idea to get in the habit of backing up your data on a regular basis. Use your windows operating system backup function to do this or follow the instructions set forth by your company IT department.
You have probably heard about Twitter and if you haven't gone to the site and looked it over, you might wonder what the big deal is and why people seem so excited about it. First, it is a social networking site and can be used for a social marketing campaign, but that should be done carefully. It is also a micro-blogging service.

Remember the days when a computer room used to be the sanctum of pure air and a dust-free zone? All carpeted and air-conditioned? Today you have your computer in your den and your laptop lying on the floor. Does that mean that your computer is susceptible to malfunctioning? Yes, it is! Although computers today are better-built, saves power and generates less heat, still no computer is immune to dust and dirt. It is thus of paramount importance that you keep your computer clean in order to ensure that it functions properly.
What will dust cause?
Dust will affect the most important part of your computer; the fan that keeps your central processing unit CPU cool. Dust lodges itself on the fan blades and clogs it resulting into excessive heat generation. The fan then fails to cool the CPU which may eventually completely stop the working of the computer. A partially functioning fan due to dust clogging will make your computer work harder with less output but a definitely higher electricity bill. So yes, you would want to stay off the dust!
So what are the precautions?
You can follow these steps in order to clean dust from the fan of your computer. Keep the computer in a dust-free environment. Avoid smoking in front of your computer. Nicotine and tar residue harm the computer. Try dusting it very regularly and use a CPU cover if need be. Also it is a good idea to keep your computer in a cold environment. Even if air-conditioning is not possible, try keeping it away from the sun, or near open windows. That being said, do not keep your computer in a closed area either. This may heat up the CPU and make it work harder.
A casual dusting of the keyboard, the monitor or cleaning up the mouse will also help in the long run. Remember dust accumulates in the mouse ball and makes the mouse interactivities quite difficult.
However even after you have taken all the precautions, dust will still accumulate on the fan. There is no alternative to regular cleaning.
So how do you clean the fan?
Open up the back of your CPU. Use a can of compressed air and an anti-static cloth to clean the dust. Hold the can vertically and spray air such that dust is not sprayed on other parts of the CPU and the circuits. Now use the anti-static cloth to clean off the dust.
Do not attempt to use a vacuum cleaner as that might cause static electricity and may also draw in any loose wiring. Adopt a liquid free dusting method and do not use any oil-based cleansing agent.
If you are not comfortable with cleaning it yourself then drop it at a service center. It generally does not cost a fortune. To keep your computer running in a good condition and to give it a longer life, keep dust off your computer. Do not ignore the maintenance of your computer, even in the busy life find out time to clean your computer.
A data center is an outside location that houses equipment and information that is used for your business. This information or equipment can be accessed from a remote location. Many businesses use a data center, especially when customer information must be retrieved. This is especially true with customer service centers. When you call with a question or problem, you may get a different call center each time. However, they are able to pull up the same information every single time. This is because they are pulling that information from a data center. This allows for retrieval of information from all authorized parties at any time, which also results in consistency.
With such access, this may make one wonder how secure a data center really is. All of this information is being transferred to and from using a computer can seem somewhat dangerous, especially since much of the information is very sensitive.
That is why it is important that each data center be equipped with top-of-the-line security features that protect that information:
1. Encryption: Encryption is a code that cannot be cracked. The information is transferred in this encrypted form that only the computer it is going to can decipher. The information that leaves the computer is once again encrypted to be stored in the data center. This is what prevents a lot of the information that is going back and from being stolen by hackers.
2. Password protection: It is important for the password to remain protected. If the password is entered incorrectly, then it is important to have a security feature that locks someone out after three attempts. This prevents someone from intruding and in order to unlock it, they must answer a security question.
3. Individual security: This is when each individual receives their own username and password to access the data center. This means the encryption key for each user is unique.
4. Redundant power: A data center that runs on redundant power is one that is going to survive such incidents as blackouts. This means they are running from separate sources of electricity and they also have backup generators. That way, if the power goes out there and not at your facility, you're still in business.
5. Verification at each end: Every single time a file is written to disk at the data center, their integrity is verified. They are verified each time they are written to the disk. If verification fails, it is transmitted to an identical server.
6. Protocol security: Protocols such as HTTP are vulnerable to hackers, so a secure data security system uses one that hackers do not target.
7. Firewalls: The firewall that is used should be similar to those used on home computers so that the business can connect with backup software and not be locked out.
8. Restricting remote access: This only limits access to certain IP addresses. This is so someone cannot access the data center from another location when they aren't supposed to.
9. Virus protection: Viruses come in all shapes and sizes and the data center must be protected as well. Virus protection keeps the data center virus free.
10. 128-bit Secure Socket Layer (SSL): This is what you want to see to make sure information is not retrieved or corrupted in any way.
So if you're looking for a data center that can make your business as successful as you want it to be, these are ten security features that you can look for that will make a large difference in how securely you do business. You can also confidently ensure your customers that their information is safe.
