Difference Between Netbook And Notebook

We have all heard of a Netbook as well as Notebook. Before we get into the difference between them both, let us see what exactly is a Netbook and a Notebook.

Notebook: Notebook is a term used for portable computer, sometimes interchangeably in place of a laptop. However it is thinner and lighter and has a better battery life than a laptop.

Netbook: Netbook is a small version of a Notebook, which is used mainly for travelling purposes.

Besides this one liner definition for each of them, we will understand them better once we see the difference in their functionality and architecture. So, what really makes them different?

Here are a few points listed that would clear how a Netbook is different from a Notebook.

1. The screen size for Netbook is between 7 and 10 inches and the screen size for Notebook is between 10 and 17 inches. So the Notebook is bigger in size, while the portability of Netbook is better since it is lighter in weight.

2. A Netbook does not have an additional Storage Drive but instead has ports so that external drives can be used along with it and a Notebook has all the inbuilt drives as present in a Desktop.

3. A Netbook, because of limited features, is less expensive than a Notebook. A Netbook is used mainly for surfing the net and using basic computer accessories, while a Notebook is used for all functions since they are equipped with powerful processors and a better resolution than a Netbook.

4. With respect to processor Netbook uses a processor that would use less power like Intel Atom Processor, and since the processor would have less speed, as the hardware is less there, the battery stands for a longer duration. The battery can continue for as long as 10 to 12 hours without charging intermittently. On the contrary, a Notebook uses either Intel or AMD processors and works well since it has a large hard drive and can handle the power used by the same. In Notebooks, the battery drains much faster since they have a larger screen size.

Difference Between HTTP and HTTPS Protocols

When we wish to surf pages on the net, we usually write the URL in the address bar for each of them starting with http:// or https://. What makes the web address different while using any one of them, keeping the entire address same besides this and where lies the difference? Let us understand what each of these, http and https stands for followed by their difference.

HTTP:

HTTP or Hyper Text Transfer Protocol symbolizes how information is transferred in to and fro direction between the client machine and the web server. Here, protocol signifies the language in which the information is transferred. Hyper Text Transfer Protocol transmission would take place over PORT 80, via a wire. When you write http:// in the address bar, it indicates that the website you are visiting is lacks security features, enough to caution you, not to share confidential information across the net. The information transferred to the website can be available to third party making it vulnerable.

HTTPS:

HTTPS or Hyper Text Transfer Protocol Secure is a safe and secure way of transferring information from the client machine to the web server. The ‘S’ in the end is what makes HTTPS different from HTTP, tagging it with extra security. HTTPS Protocol was brought forward by Netscape and was introduced as an inbuilt feature into Netscape’s browser. PORT 443 is used in HTTPS while interacting with TCP/IP, instead of PORT 80 as used in HTTP.

While we use http, for surfing normal websites, https, on the contrary is used while logging into online shopping sites where the credit card information is disclosed to maintain the security of information passed. The first page that you encounter while entering https in the address bar is “You are about to view pages over a secure connection.” The moment you type https, the interaction with the website is made secure where no third person can have an access to the details you put forward, there.

For this reason, you need to be careful that you never enter your bank or login details into any http website. The risk factor is maximum for such websites to be given your sensitive information across.

Safety Tips For Social Networking Websites

Social Networking sites are a way for users to interact on the internet. There are many of such sites that have come up and are a platform for people to form their communities, make online friends and discuss common things that interest them. A few among such are Facebook, MySpace, Orkut, LinkedIn etc. One needs to be careful what information you share on these profiles and what information needs to be kept under the covers. Here are a few of those things that you must take precaution on not sharing with others on a social networking site:

1. Personal Messages: As a net etiquette, one must not share personal information on a social networking site. In many of them, such as Facebook, the information shared is displayed on the wall, which is visible to everyone. If it’s a personal note, it may not be appreciated by a lot of others.

2. Sharing of Contact details: One of the major security threats would be to post your contact details on the net. It would be an open invitation to the intruders. If you are going on a vacation and post those details on the net as well, you are inviting burglars indirectly to pay a visit to your house in your absence.

3. What you feel about your workplace and employers: You must be careful in not to disclose information related to your workplace as well as gossip or talk ill about your seniors on a social networking site. This can stake your job as well as create bad relations with people at work. Some organizations even fire employees and take things discussed on such sites in very serious terms. For this matter, websites such as Facebook are blocked and employees don’t have an access to those in their organizations.

4. Inter-linked sites: People who use one social networking site are bound to use one of the others too. Many of us are a part of Facebook and LinkedIn at the same time. Considering the same scenario, if you share some information on Facebook, it is quite likely that the information may be accessible on LinkedIn too. This applies more so, when two sites are linked to each other on one of your profiles. So what you post on one is accessible on the other too. Considering that you post contradictory information on both these sites, it can affect your job and your employee status.

5. Password: This is the worst bit of information that can be shared on the net. Passwords and password retrieval questions need to be kept as secure as possible. For password retrieval hints, don’t choose a very common question, the answer to which can be guessed by anyone. Once your password is taken by another person, your account can be misused.

Social networking sites are meant to socialize and keep in touch with your friends and create and add more to your existing circle and keeping these few criteria’s in mind, it is all safe.

What Is New About Windows 7 ?

Windows 7 was introduced with 6 editions, each unique in its own way and yet supporting some common functionality. Each edition supports 32 bit processor. For those users who have been using the earlier introduced Operating systems, Microsoft came up with ‘Windows anytime upgrade’ which enables you to upgrade your machines to Windows 7 edition of your choice. However before upgrading, you would need to know which edition you would like to go in for. So let us have a look at what is new and different in basic features offered in each of these editions and how it makes one different from the other.

The 6 editions offered by Microsoft Windows 7 are:

1. Windows 7 Starter
2. Windows 7 Home Basic
3. Windows 7 Home Premium
4. Windows 7 Professional
5. Windows 7 Enterprise
6. Windows 7 Ultimate

Windows 7 Starter

This edition of Windows 7 has the least features amongst all other editions. It is basically meant for surfing the net. This was made for less 32 bit computers and one major feature that is missing in this is the Aero theme. This edition is not available in the retail stores and comes installed with new notebook purchase.

Windows 7 Home Basic

For users who prefer using Windows 7 Home Basic, they need to activate Windows as it includes geographical activation. It has better features than the Windows 7 Starter edition but is sold only to developing countries.

Windows 7 Home Premium

This edition is for home usage and comes with a great user interface. This edition has Windows Media Center to enable users to play, create and burn Media files with ease. It has advanced Windows navigation too like multi touch support.

Windows 7 Professional

Besides encompassing features of Windows 7 Home Premium, there are good amount of networking features added to this edition of Windows, the most prominent of them being Location Aware Printing. This works if you have to use your laptop in different places and thus default printers for each location can be selected. Another important feature which cannot be neglected here is the Remote Desktop where other PC’s can get an access to yours through internet. Another highlight that is available in Windows 7 Ultimate besides Windows 7 Professional is that a licensed version of Windows XP can run inside Windows 7 through Virtual PC.

Windows 7 Enterprise

It is sold only to companies which have Microsoft Software Assurance.

Windows 7 Ultimate

It encompasses all features of Windows 7 Enterprise, but to be used by home users. Windows 7 Home Premium and Windows 7 Professional users are allowed an upgrade to Windows 7 Ultimate using Windows Anytime Upgrade feature. The biggest advantage of Windows 7 Ultimate is that multiple languages are allowed on one computer.

Other than these 6 editions that were declared officially with the release of Windows 7, another upcoming edition is the Windows thin PC which will be up in the market in 2011, as declared by Microsoft.

Tablet PC Comparison 2010

A tablet pc is a bridge between a laptop’s functionality and a Smartphone’s portability. Let us have a glimpse at top 3 of them and compare what makes them better than the other to enable us to decide on our choice before going ahead and purchasing one of those fancy as well as a handy and a useful piece of tech item for all those who are forever on the go!

Apple iPad

Apple iPad is clearly the most dominating tablet as of today and best one to invest your money in. Along with a good display and a cool interface it is also equipped with a good battery life extending up to 10 hours. Since Flash is missing, it makes many applications handicapped and the lack of camera brings down the dimensions of this tablet multifold. But the fact that it carries the trademark of Apple, itself convinces that users would not regret purchasing this piece. For a couple of features missing, it still is the most promising tablet available in the market.

HP Slate 500

One of the most promising and ubiquitous tablets that has genuine Microsoft Windows 7 Professional 32 bit installed on it and an Intel Atom Processor. For those users are comfortable using Microsoft operating systems, this one is a strong recommendation. All applications that have been built for windows are applicable here. Appearance wise, it’s got a good, solid built. The screen is good but it’s recommended not to use this under direct sunlight. Since the VGA output is missing, there might be a problem connecting to projectors as majority of the projectors use VGA.

Performance wise, the tablet is quick and boots within seconds with a fast screen rotation. Finger print reader is however missing, which is meant to be an integral part of business tablets. Cameras have a low resolution but works well for video conferencing. As with all tablets, if used a lot for typing, a traveling keyboard is recommended.

Dell Streak 7

Before Dell Streak was introduced, there was a wave whether the Streak Tablet will top the iPad or not? It is 5 inch high resolution tablet which comes with sufficient accessories and uses Android 1.6 Operating system. The screen is visually appealing but takes time to switch between both the modes of the tablet: portrait and landscape. It has a Qualcomm 1GHz mobile processor. Now this one carries a front facing VGA camera and it supports 3G, is Wi-Fi enabled and has Bluetooth to facilitate smooth internet surfing experience while you are on the go. Battery life is a drawback and just like HP’s Slate, the touch screen feature isn’t too good either. Besides few of these drawbacks, the design of Dell Streak stands out. Booting time hardly takes few seconds so speed is placed at a good average. It’s a multipurpose tablet with which you can use the phone, browse the net and the camera is a wonder which gives clear and sharp images.

What Is A Computer Virus And What Does It Do?

A computer virus is basically a program which enters and gets installed on your computer and which can simultaneously execute or run on its own when a specific type of file is clicked. A virus can enter a computer either when you receive an email or you transfer a file, which is infected from one computer to the other.

The effect of a virus can be fatal to the machine to the extent that it gets damaged, files can be deleted, corrupted, boot sector over–ridden and hard drives could stand formatted. A virus would be generally a program which either executes on its own or asks for execution such as an exe, SYS, OVL, OBJ, PRG, MNU and BAT files.

Generally a virus would be attached along with legitimate program and would execute as soon as a genuine program is executed. This is done so that the user is not aware about the virus getting executed and in the meantime the virus would have done its part.

Many times a virus changes its code on its own when it moves from one computer to other. This is done so that user is not able to make the virus ineffective.

In India generally W32/Coronex-A viruses are found which will affect the address book and start phishing mails or fraudulent mails and fool other users.

Various types of Computer Viruses are:

1. Resident virus: These are the viruses which reside in your PC’s RAM. These viruses end up corrupting various programs that are installed and running on your machine.

2. Boot Virus: These viruses reside on the boot sector of your hard drive and thus it affects the operating system.

3. File Virus: These affect the .exe files to which they get attached.

4. Multipartite Virus: These viruses are a combination of Boot and File Virus. These viruses cause maximum infection to the machine since they affect both the boot sector of the hard drive as well as the files stored on the PC.

5. Network Virus: This is the virus which spreads through LAN and via Internet.

6. E-mail Virus: This virus gets attached to all the contacts in your Email list and it spreads once the mail is opened and viewed.

7. Macro Virus: All programs like MS Office that use macros get infected by this virus. These viruses are operating system independent meaning they can affect any system irrespective of the operating system it uses.

There are various anti-viruses and firewalls that have come up to counter affect these viruses and stop them from attacking your PC. Some of the common and most widely used are BitDefender, Norton, F-Secure, ESET NOD32, Kaspersky, TrendMicro, Panda, AVG, McAfee, ZoneAlarm and GData. The best way to protect your PC is to use a good anti-virus program that is updated regularly and simultaneously use a good firewall too.

What Are Internet Cookies?

You must have heard of ‘cookies’ stored on your computer and that at times you need to clean them regularly while at other times they are useful for fast and easy filling in of forms and information on the net. So what exactly are these internet cookies or web cookies and why are they needed?

Internet cookies are the files that store data on the user computer and the server. The reason for storing this data is so that when required, it can read it for a fast access and simultaneously, saving in a lot of time while entering information in a website, since that bit of information has already been collected and stored on the user’s PC. Cookies are mainly stored by online shopping websites to keep a track of your purchases and information entered and save you from entering them again and again.

How these web cookies function can be understood better following this example. When a user visits a website, the first time the web server tracks the visit and with every subsequent visit thereafter, it checks on which pages are visited more often than the others by the server gathering cookies from your browser and keeping a track of your surfing.

The kind of information cookies trace are your computer’s operating system, browser that you are using, your internet connection, and IP address. Cookies are usually safe but all cookies can’t be trusted that can track confidential information you share on the net. Cookies can be classified into two types:

1. Session cookies: The life span of these cookies is till an individual’s stay on a particular website. The moment that particular website is closed, the cookies associated with it are gone too. Session cookies are there to enable a user to surf easily, where the information about each page visited, gets accumulated simultaneously.

2. Persistent cookies: These cookies are stored on the PC and each time the user visits a particular website, the cookies enable the user to enter information that has been entered before and now saved as cookies. Every browser has settings where you can fix the amount of time you want the persistent cookies to be stored.

Pros

Once cookies are stored on a website, the user need not enter the same information manually every time. Information that has been fed the first time can be retrieved later.

Cons

One security lapse that a cookie has is, anyone using your computer can access your important information stored via cookies.

What Is RSS Feed And How Does It Work?

RSS Feed is a short form for either of the two: Really Simple Syndication or Rich Site Summary. To explain the concept of RSS in simple terms, it is used to let the readers of a particular website or a blog know that the website they have subscribed to, has been updated.

To understand better, RSS is an improved version of bookmarking a site, where the reader does not need to do things manually as they are expected to do, while maintaining bookmarks, which usually gets messy when you are required to keep a track of a lot of websites in one go. RSS feeds rather get updated about every minute change in the website through a feed-reader which allows one to read updates from a particular site that you have been subscribed to.

RSS Feed Benefits

1. Easier to maintain a track of your favorite websites and get regular updates from them without the need to manually check each one, on a regular basis.

2. Website owners can easily get to let their subscribers know of any change to the website, once they submit regular feeds to RSS feeds.

3. Rather than searching all over the place, you can get all your favorite information in one place.

4. It’s literally impossible to miss out on important information, once you are subscribed to RSS feeds.

5. It saves a lot of your time and you get the most handy information right on your PC as quickly as a webmaster updates the website.

6. Email need not be shared for you to get updates, so your inbox is free of unnecessary spam and there are no security issues.

How To Setup RSS Feed?

Now that we have an idea, what a RSS Feed is, let us come to the next part and learn how the RSS Feed actually works.

The way a RSS feed or RSS channel works is based on a very simple technology. RSS feeds are XML files which are coded and safely stored on a server. Once these Feeds are created, they are linked to your website where when the users subscribe they get details brought across to them on a regular basis with the help of RSS Aggregators. RSS Aggregators or RSS readers, explained simply are computer programs that collect all the information or feeds in one place and organize them for the subscriber’s easy reading.

Example, there is a feed called Paint shop pro tutorials, once you are subscribed to it, you will get all the stuff related to this from different websites, in one place which helps in saving a lot of time, searching for the details on the net, visiting each website individually. Thus RSS feeds are useful to every web surfer to a large extent besides having great features for website owners too at the same time.

What Is Cloud Computing And Its Benefits?

Cloud Computing is one of the most talked about concept in Technology. In simple terms it can be explained as Internet computing. Let’s see how Cloud Computing works. When we say that the computing involves working on the net, in simple terms it implies that you do not install any of the software programs or upgrade your PC’s hardware for it to comply with those programs. The internet would take care of both the software as well as the hardware. Since both of them are virtual, this computing is referred to as, within the cloud or Cloud computing.

Just to give an example it would mean, instead of installing the Microsoft Word, you can access your word applications via Google docs, available to us on the Internet. Thus this “cloud” manages all your applications in a similar manner.

Next question that arises in mind is why we need Cloud Computing, when we can manage using each of these applications on our individual PC’s. Well, there are definitely a whole lot of advantages that would compel any user to opt for this technology. Here are a few of them:

1. We don’t have to worry about purchasing expensive software and installing them on our PC. This way we would save a lot of money. Any software can be accessed remotely for us to use at our convenience. There would be no compatibility issues as the software is not running on our PC.

2. We save a lot of time, that otherwise would be used to install and update every software, present on the PC. Just the way our email client like Hotmail, Yahoo and Gmail gets updated automatically, same would be the case with each of these applications.

3. It is safe and risk free. Today when you need to take the responsibility of backing up your data, lest the hard drive crashes, in Cloud computing, the respective vendor will do the needful. We don’t have to worry for any of it.

4. Server issues are not new. We’ve all had our share of trouble with them. In this scenario, Cloud computing would take care of them again. In the first place, there won’t be any server issues, because there will be multiple servers ready to take over, even if one of them crashes down.

Cloud Computing as we can see forms the base for the future of technology and has lot of benefits. There seems to be a lot in it to look forward to and seeing the impact that it has already created it is bound to take the technology world to new heights.

What Is A Good Web Browser To Use?

A browser is a platform which enables us to view the world wide web (www) pages. Some of the most popular browsers are Internet Explorer, Mozilla Firefox, Opera, Google Chrome and Apple Safari. Besides some common features, each of these browsers is equipped with some unique ones to help you decide which one would you like to pick up for your internet usages.

The kind of Internet browser you have, will determine on the kind of web surfing experience you enjoy. Even though most people download a couple of browsers to use them for different activities, it is however recommended, not to. Using too many browsers at the same time can create a conflict amongst them and you may find many of your web applications not responding properly.

Now coming to which browser would be the best to surf the net, here are a some basic features one needs to keep in mind:

Ease of use: Along with a stylish look, the browser needs to be such that even novice users feel comfortable while surfing the net. Too many complicated features will create confusion in the user’s mind. In contrast it should provide an easier way to surf, such as tabbed interface and inbuilt web-search.

Good Security: This is a prime factor while deciding on the browser one chooses. We are all aware of certain websites giving a virus attack to our PC’s, as soon as we visit them. Most of the times, we are unaware which of these websites are harmful to browse. A browser should not be vulnerable to such attacks. At other times, pop-ups intrude and hamper the smooth browsing. So a browser needs have an inbuilt pop-up blocker too. Another aspect one needs to take care of is ongoing phishing, where a user’s sensitive information like password and credit card details can be easily leaked out. A browser with good security features would see to it, that you can have a relaxed online experience.

Speed: A browser should be equipped to provide good surfing speed. It should not take ages to open a graphic intensive page and java enabled applications. Along with the internet speed, browsing speed also depends on how long your browser takes to process the pages and run scripts on them.

These are a few things that you would need to keep in mind while selecting web browser, so as to make your surfing experience an enjoyable one.
