GOOGLE BUZZ

Google Buzz - Social Networking Website

Google Buzz is an extension of the Google Mail service offered by Google which the Internet giants hope will lure users away from alternative services such as Facebook.

Google Mail initially created shockwaves when first introduced as they offered a huge 1GB of storage space for messages and attachments compared to most of its competitors who at the time offered a feeble 2 to 4MB. Today they offer a huge 7GB as standard however times have moved on and alternative providers such as Yahoo Mail and Hotmail also now offer an almost unlimited amount of storage space free of charge.

Despite not having the advantage over the competition in this respect any longer, Google Gmail continues to be a popular service due to its ability to integrate well with other e-mail accounts and the way in which it allows you to manage your messages. As an example, Gmail groups together messages that are of the same subject, making them part of a conversation file. In this way you can manage large number of e-mails grouped into the same conversation quickly and easily so that deleting or achieving them doesn’t cause a headache.

Google Gmail is free to use and paid for by advertising however the adverts are very small, non-intrusive and are targeted so that they are more relevant to subject matter that you might find of interest. There are no large graphic adverts and no pop-up or pop-under adverts to clutter your browser.

Google Buzz is a social networking application integrated into Gmail. It aims to offer a better method to share photos, links, videos, and events with your Gmail contacts and personally I believe it is rather coincidental that this was developed after Facebook announced plans they were developing their own email system.

Buzz has all the basic features that you would expect from a social networking application including the ability to share status updates, photos, links and videos both privately and publically. You can choose who you’d like to follow by simply entering their Gmail address at which point they can be added as a friend for you to see a steam of all their updates that have been shared either publically or privately with you. As with Facebook, other users can comment on public posts and show their appreciation for an update or users status by clicking the ‘like’ button.

You can direct a comment into a fellow users Gmail inbox by simply putting @ the beginning of your comment and the user name of that person is then hidden to protect their privacy. This feature can only be used with people that are in your Gmail contact list. Also by clicking on the arrow to the right of any post, you can link content to the post, email the contact directly and mute the buzz that appears in your inbox.

Google Buzz also integrates with Picasa, Flickr, Google Reader, YouTube, Blogger, and Twitter meaning that you are able to share content from these applications directly. This is a nice feature as it allows you to post files and albums you may have already created without having to go through the hardship of creating them twice.

The social networking market has the potential for huge rewards, especially for a company such as Google that makes such a large amount of its profits from revenue generated by advertising. With news that Buzz will soon be available on the Android phone and iPhones platforms, it will almost certainly give the more established social networking sites a run for their money.

Hello Guys,

I am Ryan Mendoza, a computer enthusiast, but as you may know, I am not a graduate of any computer courses that we have in schools. I am just a computer hobbyist who want to explore more about computers. Actually, I am a graduate of Commerce. When I was college I don't know what course I'm going to take until I finished my degree. It is when I was working as a Transcriptionist got my passion in computers. The technical supports in my previous company really influenced me to learn more about computers. Since then, i hone my skills that I have right now. I am more into hardwares (basic troubleshooting skills). When there are things that I want to know or things that I encounter that I don't know when I am troubleshooting a computer, I research it and I don't stop until I found the answer for that. There are a lot of sites that can help you learn in today's computing and one of those is tipidpc.com. Just create an account there and browse on their forums, and poof, you'll gain knowledge. Or post a forum, ask what you want to learn or know, then there are a lot of helpful guys and gals out there who can help you out.

4 Main parts of a computer

There are four main parts which a computer system needs to function effectively and that are critical to system performance. If a part is malfunctioning, it can cause the system to stop operating, it can cause program errors or it can slow down the performance of other devices. Understanding how these parts and devices interact within the system can optimize hardware and software performance.

Motherboard

The motherboard is a printed circuit board which uses "bus" architecture to map out critical system components and provides connectors for devices such as, the power supply, memory, hard drive, input/output slots and the central processing unit (CPU). If you examine a motherboard, it looks like a street map. The lines on the motherboard are physical addresses to a device which carries instructions to the central processing unit which is the brain or scheduler of the computer system.

Central Processing Unit (CPU)

The central processing unit (CPU) or brain of the computer system processes complex functions in the system. The CPU chip receives instructions from the system board and software applications. Today's CPUs can process data measured in milliseconds. The CPU also has a co-math processor built into the chip to handle mathematical functions. For example, when a spreadsheet program, such as Microsoft Excel calculates formulas, the program is accessing the co-math processor function of the CPU.

Hard Drive

Since the days of 20 megabyte storage, hard drive devices have come a long way. A hard drive stores programs, data and information. The most important attribute of the hard drive is the boot sector record which reads information from the disk to "boot up" the operating system for a person to use software applications. Modern hard drives have RAM memory chips sets built in to help send a program application to the CPU.

RAM/ROM Memory

Random Access Memory (RAM) is an integrated computer chip used to access any memory location or address on the motherboard directly. The RAM chips are made up of millions of circuits and capacitors. RAM is active when the computer is turned on and while the computer is on, it helps allocate memory to system operations, especially the CPU while releasing other devices and processes which are not actively using RAM resources. Random Access Memory (ROM) can only be read from the system and primarily holds the instructions for the performance of low-level system devices. Without instructions located in ROM, a user would not be able to power up a computer.

FACTS ABOUT COMPUTERS

Computers organize business information, manage household budgets, provide entertainment and fun, and connect us with the world. In short, modern life would be unimaginable without these technological marvels. However, the computer is not just a single device, but a system of different parts.

System Box

The computer case is what we normally think of when they talk about a computer. This box contains, at minimum, the CPU (Central Processing Unit), a collection of electronic circuits that act as the brain. It can also house RAM (Random Access Memory), which stores temporary information as you operate the computer.

Hard Drive

The hard drive is a long-term storage device that preserves information on a disk even when the computer is turned off. Though typically stored within the system box, a hard drive can also be external and attached via cable. The cost of hard drives are constantly dropping, making it cheaper to buy a system with less capacity, and then to expand storage by buying drives later.

Input Devices

Input devices let you enter information into the system. Common examples include a keyboard, for entering text, and a mouse, for moving and activating icons in a graphical environment. Other devices include: for multimedia, a webcam for captures of still and moving images, and a microphone for transmitting audio communications.

DVD/CD Drives

CD and DVD drives are typically built into the system box, and allow the transfer of information through the use of hard media. CDs typically play music while DVDs play videos. However, both types store files and documents, since the typical drive cannot only retrieve data, but record it as well.

Monitor

1. A monitor is how we receive information in a visual form, which can consist of text, images and video. Though these display devices used to consist of bulky CRTs (Cathode Ray Tubes), they now appear as compact, energy-saving LCDs (Liquid Crystal Displays). This external device is controlled by video card, which is located inside the system box.

Speakers

2. Speakers deliver audio information such as music from CDs, sound from games or voice from Internet chat. Though they may be built into the box or monitor, the best ones typically stand alone and may consist of an amplifier, multiple speakers and a subwoofer. They require an audio card that is located inside the system box.

Printer

3. A printer produces hard copy versions of computer information in color, and black and white. This information can consist of text from word-processing documents, photographs from digital cameras or artwork from graphics programs. Inkjet printers are initially cheap, but use expensive inks. Laser printers are faster and initially expensive, but their long-lasting cartridges produce cheaper printouts.
