You wake up one morning from a rather tiring overtime in your home office; you turn on the PC and went to the kitchen to prep up some coffee. When you got back to your desk, your PC still seems asleep so you went out to fetch the newspaper. You go back to your desk, and you just say to yourself, "Why is my computer running slow?"

You are not alone; so don't fret about it too much. There are so many computers that go through this stage for so many reasons. One of these reasons is a cluttered registry.

The Windows operating system depends on the registry to tune things up with the hardware components and software installations. The registry serves as the cache or database that collects all the information about anything that is attached to the computer, be it hardware or software.

Over time, this cache gets really cluttered and disorganized. When this happens, the OS will have difficulty accessing the necessary files to boot the computer well. You see, at startup, the computer will refer to the registry for all the events that are programmed to occur based on the installations of the user.

If a person decides to uninstall an application, that program is no longer able to run but its tail and so many traces of it are still residing in the registry. If all uninstall procedures fail to pull all their files from the registry for deletion, then the registry will be in such a mess - and the computer will tend to slow down.

When it happened to me it also hit me that the other major factors that make me ask, "Why is my computer is running slow" are the spyware, malware, and viruses, which often come with the programs I installed carelessly.

If you are asking, "Why is my computer running slow?" - you might be in need of a registry cleaner. This program will help you take care of the clutter in the registry and give it a nice, organized space for the next installations.

There are two types of registry cleaners - the stand-alone, or the one, which is part of a utility suite. Any people prefer to use the stand-alone since they think these programs run more efficiently because there are no other unnecessary functions aside from cleaning and clearing. Other users get the utility suites that include sets of tools that are packed together in one interface for so many uses.

The computer's registry can be likened to a brain that is too full of trash or unnecessary information. Often, the person will have senseless thoughts or mental blocks and that affects his overall function as a social being.

"Why is my computer running slow" is a question that can be addressed by making sure that you take care of your personal computer properly. That is part of your responsibility if you want to continue getting the best out of your machine. It is also best to be very careful with whatever you install since all the files that go with the program will sit in the registry and contribute to it's being bloated and dysfunctional.

Almost all advanced Cisco routers and switches are equipped with the Cisco proprietary operating systems called the IOS (Internetwork Operating System). Cisco PIX firewalls have a special operating system, the PIX Finesse OS.

In some versions of the IOS, there is a MIB (Management Information Base) module integrated into the IOS operating system. The MIB is an operating system component included with all recent IOS distributions that allows network administrators to view and manage device memory over the network. MIB is prerequisite software for other applications that deal with Cisco memory management, reporting data to RME (Resource Manager Essentials) and during installation of other additional software to a given device.

Before discussing the reasons to upgrade your router's memory, the following is description of the different types of memory that used in a Cisco product.

Processor Memory

This memory acts similar to the CPU cache in a computer, controlling all basic computing operations of your switch or router. Regardless of any other memory being used, the processor memory is always the first memory that is accessed and used. All the files needed for booting and essential system files required for functioning for any Cisco device are stored in the processor memory. If you are using a product that has IOS before 11.1, then the total of all types of memory is reported as the processor memory.

Flash Memory Card/Disk or Cisco Memory Card

The flash memory is a special type of programmable memory that is used to store images of the IOS software on it, in addition the flash memory is used to upgrade versions of the router or switch being used. The term 'flashing a product' means upgrading the version of IOS stored on the flash memory card.

Shared Memory/RAM (Random Access Memory)

The reason this is often referred to as the shared memory, is that it is erased every time the router is restarted or when the memory is deliberately cleared. This memory is usually the easiest to upgrade. The RAM stores all data that is temporary in nature, and upgrading the RAM usually helps improve the speed and the computing power of the Cisco product. It is generally cheaper than Flash memory, and manufactured both OEM by Cisco and by third party manufacturers, such as PC Wholesale.

While PIX firewalls and the routers that IOS runs on ultimately have finite processing power, this is often not the bottleneck that first limits their ability to grow. More often, IOS is hampered by having allocated as much (or more) dynamic Random Access Memory (DRAM) than it has available. Older firewalls and routers, which shipped with very small Cisco memory (Flash) cards, the factor limiting the usefulness of the hardware may be the Operating System installed on it.

IOS and PIX OS each have vastly larger memory footprints than they did as recently as a few years ago, and the current versions of these operating systems require more memory than many devices are equipped with. Both the RAM and Flash memory of a Cisco router can be upgraded. Such an upgrade may significantly extend the longevity of a network operating with older equipment. Two of the principal reasons to upgrade your devices memory to increase its speed and to run the most current version of Cisco IOS.

Increasing speed

Just like conventional computers, increasing the memory of a Cisco product increases its speed. If the product is a Cisco router or switch that handles large amounts of data over the network, increasing the RAM of the product can improve both the processing speed and the device's performance.

Upgrading the IOS

For devices with Cisco IOS 11.1 or older the only way to improve its performance is to upgrade the IOS. However, older Cisco hardware is usually not equipped with sufficient flash memory to store a newer version of the IOS. In this case, the only option is to upgrade the flash memory of the Cisco product. All versions of the Cisco IOS after version 11.1, used by most Cisco routers and non-firewall hardware around the world, has functionality to report MIB values over the network via SNMP (Simple Network Management Protocol), allowing network administrators and other authorized device managers to make queries to the database from across the network. Obsolete versions of the IOS, without the MIB module, do not have this functionality and can only report the size of processor memory.

Family and friends can be pretty far flung these days, so how do you keep in touch? Snail mail and phoning are good options, but it's fun to be able to share pictures. With the advent of digital cameras, it's easy to post pictures on a blog or website, or send pictures via email.

Of course, film cameras will work, as you can scan and convert pictures to digital files, but the easiest way to send pictures quickly and cheaply is to use a digital camera.

How To Find What's Best For YOU When Buying A Digital Camera

There are all kinds of digital cameras available these days, so the trick is to find the one that suits your needs and budget. If you are buying your first digital camera, the lingo and technology are a bit different than for film cameras, so before shopping take time to learn a little and figure out what you'd like to buy.

First, what kind of photographer are you? Do you like total control over the picture taking process, or would you rather just aim the camera and push the shutter button? Then it's also helpful to decide what you want to do with your pictures. Do you just want to put them online or send them via email, or do you want to be able to print them, and if so, how large do you want your prints?

If photography isn't your passion, and you just want to have pictures to share, buying a simple point-and-shoot digital camera is probably best. It has automatic settings, so all you have to do is aim the camera, press the shutter and viola! Instant picture!

However, if you prefer more control over the picture taking process, try buying a mid-range digital camera. There is a wide range in both price and features. For the more serious hobby photographer, there are "prosumer" cameras midway between point-and-shoot cameras and digital SLR cameras. They offer better lens quality and usually more features than a point-and-shoot, though those little cameras can come pretty loaded these days!

Digital SLR cameras are top of the line and more expensive. These work more like traditional cameras, having a body with detachable lens. This gives you more options with being able to change lens, but it's also much more expensive. Just one lens can cost as much as a point-and-shoot digital camera! There's also usually a steeper learning curve to figure out how to use all the options on a digital SLR camera.

However, if you're buying your first digital camera, intermediate, "prosumer" and digital SLR cameras probably aren't the best choice. All the settings and features can be a little overwhelming for the beginner, and your expensive camera may end up collecting dust somewhere. Try a low to midrange camera first and get a feel for digital cameras and what features are most important to you. Then when you're ready to move up and buy a better digital camera, you'll have a better idea of what to look for before you lay out your hard earned cash!

What To Look For When You're Ready To Buy A Digital Camera

You can buy digital cameras in all sorts of places these days, from fancy department stores to discount stores, photography/camera shops and many stores online. While you can sometimes find great deals on-line, if this is your first digital camera, go to shops and look at different cameras if at all possible. It helps to pick it up and get the feel of the camera in your hand to see if it's comfortable and the controls are easy to use, and you can check out what features it has and how they work.

But what exactly are you looking for?

A pixel makes your picture....

One of the first things to check out when buying a digital camera is the MEGAPIXELS. A pixel is a single dot in a graphics image. A megapixel is equivalent to one million pixels. A 1-megapixel camera would produce an image roughly 1200 pixels wide by 900 pixels high, a 3 megapixel would be 2048 x 1536 megapixels, and so on. Higher megapixels mean better resolution, but aren't the whole picture. The main thing to keep in mind is the more megapixels, the bigger image you can print.

Approximate Megapixels vs. Print Size

2 Megapixels prints well up to 4x6 inches
3 Megapixels prints well up to 5x7 inches
4 Megapixels prints well up to 6x8 inches
6 Megapixels prints well up to 7x10 inches
8 Megapixels prints well up to 10x14 inches
12 Megapixels prints well up to 16x24 inches

For email, websites and printing snapshots, a 3 to 5-megapixel camera is a good choice. If you want to make high quality 8x10 prints or larger, you need more megapixels. Higher megapixels also allow you to crop down to a smaller portion of the picture while still retaining sharpness in prints.

One other thing to keep in mind when considering megapixels and resolution, be sure you are getting optical resolution. This is the actual number of megapixels the camera records. Some cameras offer interpolated resolution to get bigger pictures from the same number of megapixels by using software algorithms to determine what color pixels to add, so the picture becomes bigger at the expense of clarity.

Opt for optical...

Digital cameras have two kinds of zoom, optical and digital. In this case, focus on the optical zoom. It's the one that actually uses the lens' optics to bring the subject closer. The higher the number, the further away you can "pull in" your subject. The digital zoom merely takes the original information and makes it bigger, and once again, clarity is sacrificed. Most serious photographers turn off digital zoom. Stick to optical!

For Your Viewing Pleasure...

Digital cameras commonly use an LCD screen instead of a viewfinder to focus on your subject, though some come equipped with both. Check the size of the screen when buying a digital camera to be sure you can comfortably see your subject. It's also really handy to have a flip screen that allows you to hold your camera low or high, and still be able to see what's on the screen.

Fun features...

Many digital cameras offer settings for such things as burst shooting mode, which is handy if you want to take pictures of moving subjects. The camera shoots a series of pictures without pause, then writes the files to memory. Other features allow for manually changing settings, special effects, short digital movie files, using an external flash, and much more. Look over several different cameras, decide what features you just have to have, and which are on the "nice to have but not vital" list. No one camera will do everything well.

Get the Picture...

You've got to get the pictures out of the camera to share them. Usually the files are downloaded to your computer through a USB port, so make sure your computer has one. Also, keep in mind when choosing a camera, the more megapixels, the bigger the files. You've got to store those files somewhere, so how much memory is available on your computer? Does it have a CD burner?

However, you can still buy a digital camera even if you don't have a computer. Many photo labs, even in places like Walmart or Kmart, have machines with the capability of making prints and/or photo CD's from memory cards, and will make a disk of the files, sort of like digital negatives. There's also the option of buying a photo printer with a docking station for your camera. Just plug the camera into the docking station, and bypass the need for a computer to print.

Cash After Camera

When buying your digital camera, keep some cash in reserve, because there are two more important purchases you need to make.

1. Memory - The digital camera's equivalent of film, the amount of memory determines how many pictures you can take. Different cameras use different types of memory, so the first step is to find out what your camera uses. The most popular types are: Secure Digital (SD), CompactFlash (CF), SmartMedia (SM), Memory Stick (MS), MultiMediaCard (MMC), and xD-Picture Card (xD).

Cameras are usually packaged with a small MB-sized card. A second card of 64 MB is good, but of course the more MB and the more cards, the more pictures you can take before having to download and erase the images. The different cards are NOT interchangeable, so be sure to buy the right kind for your camera!

2. Battery - There's nothing more frustrating than being in the middle of snapping pictures and the battery dies. Get extras. It's worth the expense to have a second battery charged and waiting should the one in your camera lose power. The rechargeable ones are more expensive, but the ability to use them over and over makes them worth the initial outlay of cash.

That's The Total Package!

There you have the basics for choosing a digital camera. Decide what kind of pictures you are likely to take, what size prints you want to make, how much zoom, and are there any extras you can't live without? Look for the camera that most closely matches your list in your price range, buy a bigger memory card and an extra battery set, and you're good to go!

Have fun sharing those pictures with friends and family!

Upgrading, instead of buying a new laptop is a more practical way to save you hundreds of dollars. Understanding the needed specifications and following the easy step by step process will help you find the right materials for the upgrade, at a very low price.

Upgrading your laptop hard drive can be done easily. If your laptop was manufactured last 1997and has 3.0 GB or a bigger hard disk drive, the choices to upgrade it are unlimited.

Laptop hard drive that uses a 9.5 mm hard drive height is an exemption. The exemption pertains to laptops that were manufactured before 1997. The mounting hole patterns of these laptop hard drives are standardized. It has separate screw holes situated 3 inches on the longer side.

CHOICES OF HARD DRIVES

Laptop hard drives are not owned by laptop manufacturers. Therefore, laptop hard drives will work with any type of laptop. Almost all laptops have a 2.5" mobile hard disk drive. There are also few ultra-portable laptops that use 1.8" drives.

Four things to consider when buying new hard drives:

1. The Capacity

Not all laptops can take advantage of hard drive capacities that are in excess of 80 GB. This is due to the BIOS or Operating System's limitations. To access the full capacity of an ATA interface hard drive, a minimum OS configuration of Windows XP or Windows 2000 is required.

2. The Speed

Present hard drives are available with the following spindle speeds:

- 4200 RPM - this is the spindle speed found in older laptops. It takes less power to turn the platter at this speed. It has extended battery life.
- 5400 RPM - New 5400 RPM disks gives an improve performance with very little reduction in the life of battery.
- 7200 RPM - It has high performance. However, you need to sacrifice the battery life.

3. The Interface

Many laptop hard disk drives use an ATA interface like:

- IDE
- EIDE

New laptops are currently set up to use a Serial ATA (SATA) interface. Your laptop can be set with one or the other. ATA and SATA laptop hard drives are not exchangeable.

4. The Buffer

The temporary data storage buffer cache is being used to enhance drive performance. The buffer cache can be checked initially when data is requested from the hard drive. It is a lot faster to retrieve it from the cache as compared to the drive. Many laptop hard drives incorporate 8 MD buffers. Others are limited to only 4 MB while others may offer a 16 MB cache.

TRANSFERRING OF DATA

Transferring the files, programs and operating system from your old laptop hard drive require new steps to be followed. These are:

1. Use a Desktop Personal Computer

- Removed the old laptop drive
- Connect it to an open ATA or IDE channel on the desktop. Use an adapter.

2. Use a utility like NORTON GHOST to create the image of the drive. Store it on the desktop's hard drive.

3. Desk top must be shut down.

- Removed the old laptop drive
- Install the new laptop drive
- Reboot the desk top
- The image stored on the desktop hard drive is then transferred onto the new drive.

4. Use an external hard drive

Using of an external hard drive and a back-up utility is another method.

5. Others

The Universal EZ Hard Disk Drive Upgrade Kit for All Laptop Computers of Apricorn shortens the task. You can also use the Apricorn EZ Hard Drive Upgrade Kit of your old laptop hard drive as an external hard drive.

It also has a kit for upgrading SATA drives. It is known as the APRICORN EZ Upgrade Universal SATA 480 Mbps USB 2.0 Kit.

Removing and Replacing Laptop Hard Drives

It is necessary to know the procedure in removing and replacing hard drive units. This information must be given by your laptop manufacturer.

Step-by-Step Procedures:

1. Universal EZ HDD Upgrade Kit for All Notebook Computers:

Upgrading your laptop's hard drive fast and easy can be done via EZ Upgrade. It includes:

- External Hi-speed USB 2.0 drive enclosure

There has to be an end to the increasing burglaries and corruptions in the atmosphere and the surroundings either it is a house or a public place. We as responsible natives and the government have also to think about the precautionary procedures which we can give our selves and our family. The invention of the spy cams, the concealed cameras and rather many other types of cameras have been created evidently for all surveillance purposes. Surveillance is a process and a method by which developing business organizations can make their growth rapid and reliable. Some business organizations have not yet installed the hidden cameras in spite of the availability of the same very easily in the market. In the ultimate analysis, all the factors would result in a successful and growing organization. If the spy cams are installed at the work places, the public places and homes, then the burglaries can be prevented to a great extent, because the images captured by these cameras help to catch the culprits very easily.

This multi purpose piece of equipment can be bought and easily installed where ever we want to. We have to find the best camera for our work place and our home and see how we can make the most use of this fabulous and magnificent equipment. Modern concealed cameras are laden with modern features especially designed for surveillance principles to make every place where they are being used very functional and safe. With the use of the concealed cameras, we can get excitement and satisfaction in our life. The latest creations and the spy cams can improve and help us to expand our views and security with good organization. By using good equipments, we can concentrate on our other work and be relaxed always.

I own a fashion design institute and I have to be very alert with my work always. There are many people who come to learn the fashion designing course. I always have to be attentive about the safety of my customers and the staff. I even have to survey every action of my staff members and see that they are teaching the designs to people very tactfully. For this purpose I have installed the spy cams at my institute so that everything runs smoothly. Earlier I had not installed the spy cams because I did not feel its need. But few months ago, I noticed that there was someone who was creating a mischief and was stealing the important designs from my cabin. I was to put an end to all this mischief and so I had decided to install the spy cams so that everything would be clear. Likewise, buying the spy cam was such an easy procedure. One day I was going through the internet for some information related to my fashion designing course. Then I read an article about the advantages of the spy cams and how easily they can be available through the internet. I logged on to the website and choose the spy cam which I required and placed an order for it on the internet itself and it was shipped to my house directly with great ease.

To give a child proper education and a better living many women are deciding to step of the house to earn and also they want to help their better half in some way or the other. This way even she can be recognized with her own identity. Stepping out of the house to earn more is not very easy for a lady. But the central crisis of a woman capitalist is that she is a lady. This is for the reason that she has to think of her twin conscientiousness towards children and place of work. Women have to keep a suitable stability between their responsibilities towards their children as well as their work. Earlier they had to suffer when they would not get support from their families or husband. But today everything has changed. According to the changing trend, many couples are opting to work and there are many people who are helping their wives even with the house hold tasks. Earlier it was the sole responsibility of a woman to take care of the child. But today even the men are considering this and they are helping the women to take of both the responsibilities together.

She even has to think about the safety of her child and how and where to leave her/him. Obviously there are many alternatives like the day care centers or hiring the baby sitters for the care of the baby. But the question which arises among many working couples is how far it is safe to leave their young one with the baby sitter or the nanny or to leave the child in the day care centre? If the working couple thinks to send the child in the day care center, then they are also thinking about the child's psychology. Will the child not miss the cozy bed of her/his home? Will the child not miss those familiar toys which he/she is used to play with? Well, their thinking says that their child will evidently miss the surrounding in which she/he will feel safe and secure. Though the young one's cannot communicate their feelings, but we as parents have to understand their uneasiness and we have to try to keep them away from this insecurity. The solution to all these questions and problems is there. If we want our child to be in a safe environment in our own house, then we can employ a baby sitter for her/his care and for more precautions, we can even install a spy cam or a nanny cam in our house for the observation of the baby sitter.

Is it not easy nowadays for a lady to move out of the house without any tensions? The innovative spy cams and the nanny cams are of great use for the working couple who can leave behind their child easily at home under the guidance of the baby sitter. Above that the spy cams or the hidden cameras can be used at the work places also to see that there are no interruptions created.
