Use Pen Drive as ram memory in windows 7

Hi friends, Windows 7 and Windows vista comes with a ready boost option. 

"ReadyBoost" is a disk cache component of Microsoft Windows, first introduced with Microsoft's Windows Vista in 2006 and bundled with Windows 7 in 2009. It works by using flash memory, a USB flash drive, SD card, CompactFlash or any kind of portable flash mass storage system as a cache.
If you are using a high configuration PC, It doesn't show any effect on speed because if you are a normal user I think only a few times you use your full ram memory but if you are using an old pc with low ram memory(Like 512 MB or IGB) and harddisk & using vista or 7. It speed up your PC and you will see the result, reduced application data loading time, reduced shutdown and restart time and many more you can't imagine without High ram memory. How to use this feature

  • Plug in your pendrive-> Format with NTFS or FAT32
  • Now go to properties->Select ReadyBoost
  • Check Use this device->Choose maximum space to reserve system speed
  • Click on Apply and OK. 
Your readyboost PenDrive is ready Now to Use.

Windows 7 Contacts


Using contact in window 7
If you choose to use window mail, windows contact is integrated with windows mail.

What's in a contact?
You can store as much or as little information as you like about each contact, including any of the following:

E‑mail addresses: Store as many e‑mail addresses as you want for a contact, and set one as the preferred address.
Picture:  Adding a picture of a contact can help you remember the person.
Phone numbers: You can store home, work, cell, and fax phone numbers for a contact.
Street addresses: You can store both home and work street addresses for a contact.
Family information: You can enter information here about a contact's spouse or partner, children, gender, birthday, and anniversary.
Website addresses: You can store both home and work website addresses for a contact. 

Finding the Contacts folder
Open Windows Contacts by clicking the Start button, clicking All Programs, and then clicking Windows Contacts.

Address book are available in both your desktop mail tools and in web mail tool. Such as yahoo, hotmail and Gmail address book.

Adding a contact.

Click New Contact, and then type the information you want for the contact in any of the boxes on the available tabs. You don't have to fill in all the boxes; just enter as much information as you want about the contact.


Adding information to a contact
Open Windows Contacts by clicking the Start button, clicking All Programs, and then clicking Windows Contacts. Double-click the contact you want to change. Click the tab where you want to add information, and then type in any of the available boxes.

Adding a new picture to a contact
On the Name and email tab, click the contact picture, and then do one of the following:
To add a new picture, click Change picture, locate the picture you want to use for the contact, click it, and then click Open.

Creating contact groups (mailing lists):
You can also create contact groups, which combine multiple individual contacts into a single group. Creating a contact group enables you to send e mail to many people at once. If you send an email message to a contact group, it will be sent to everyone you added to the group. Sending email to a contact group can be a lot easier than adding names one at a time to an email message, especially if you often send messages to the same group of people.

Email Guidelines ...


DO’S
Timeliness :  Answer swiftly.
Customers send an e-mail because they wish to receive a quick response. If they did not want a quick response they would send a letter or a fax. Therefore, each e-mail should be replied to within at least 24 hours, and preferably within the same working day. If the email is complicated, just send an email back saying that you have received it and that you will get back to them. This will put the customer's mind at rest and usually customers will then be very patient!
Comprehensiveness : Answer all questions, and pre-empt further questions.
An email reply must answer all questions, and pre-empt further questions – If you do not answer all the questions in the original email, you will receive further e-mails regarding the unanswered questions, which will not only waste your time and your customer’s time but also cause considerable frustration. Moreover, if you are able to pre-empt relevant questions, your customer will be grateful and impressed with your efficient and thoughtful customer service. Imagine for instance that a customer sends you an email asking which credit cards you accept. Instead of just listing the credit card types, you can guess that their next question will be about how they can order, so you also include some order information and a URL to your order page. Customers will definitely appreciate this.
Crisp : Be concise and to the point.
Do not make an e-mail longer than it needs to be. Remember that reading an e-mail is harder than reading printed communications and a long e-mail can be very discouraging to read
Language :  Use proper spelling, grammar & punctuation.
This is not only important because improper spelling, grammar and punctuation give a bad impression of your company, it is also important for conveying the message properly. E-mails with no full stops or commas are difficult to read and can sometimes even change the meaning of the text. And, if your program has a spell checking option, why not use it?
Readability :  Use proper structure & layout.
Since reading from a screen is more difficult than reading from paper, the structure and lay out is very important for e-mail messages. Use short paragraphs and blank lines between each paragraph. When making points, number them or mark each point as separate to keep the overview.
Contemplate : Read the email before you send it.
A lot of people don't bother to read an email before they send it out, as can be seen from the many spelling and grammar mistakes contained in emails. Apart from this, reading your email through the eyes of the recipient will help you send a more effective message and avoid misunderstandings and inappropriate comments.
Clarity : Take care with abbreviations and emoticons.
In business emails, try not to use abbreviations such as BTW (by the way) and LOL (laugh out loud). The recipient might not be aware of the meanings of the abbreviations and in business emails these are generally not appropriate. The same goes for emoticons, such as the smiley :-). If you are not sure whether your recipient knows what it means, it is better not to use it.
Neatness : Be careful with formatting.
Remember that when you use formatting in your emails, the sender might not be able to view formatting, or might see different fonts than you had intended. When using colors, use a color that is easy to read on the background.
Readability : Take care with rich text and HTML messages.
Be aware that when you send an email in rich text or HTML format, the sender might only be able to receive plain text emails. If this is the case, the recipient will receive your message as a .txt attachment. Most email clients however, including Microsoft Outlook, are able to receive HTML and rich text messages.
Relevance : Use a meaningful subject.
Try to use a subject that is meaningful to the recipient as well as yourself. For instance, when you send an email to a company requesting information about a product, it is better to mention the actual name of the product, e.g. 'Product A information' than to just say 'product information' or the company's name in the subject.
Active : Use active instead of passive.
Try to use the active voice of a verb wherever possible. For instance, 'We will process your order today', sounds better than 'Your order will be processed today'. The first sounds more personal, whereas the latter, especially when used frequently, sounds unnecessarily formal.
Neutral : Keep your language gender neutral.
In this day and age, avoid using sexist language such as: 'The user should add a signature by configuring his email program'. Apart from using he/she, you can also use the neutral gender: ''The user should add a signature by configuring the email program'.
Clarity : Use cc: field sparingly.
Try not to use the cc: field unless the recipient in the cc: field knows why they are receiving a copy of the message. Using the cc: field can be confusing since the recipients might not know who is supposed to act on the message. Also, when responding to a cc: message, should you include the other recipient in the cc: field as well? This will depend on the situation. In general, do not include the person in the cc: field unless you have a particular reason for wanting this person to see your response. Again, make sure that this person will know why they are receiving a copy

DONT’S
Do not attach unnecessary files.
By sending large attachments you can annoy customers and even bring down their e-mail system. Wherever possible try to compress attachments and only send attachments when they are productive. Moreover, you need to have a good virus scanner in place since your customers will not be very happy if you send them documents full of viruses!
Do not write in CAPITALS.
IF YOU WRITE IN CAPITALS IT SEEMS AS IF YOU ARE SHOUTING. This can be highly annoying and might trigger an unwanted response in the form of a flame mail. Therefore, try not to send any email text in capitals.
Don't leave out the message thread.
When you reply to an email, you must include the original mail in your reply, in other words click 'Reply', instead of 'New Mail'. Some people say that you must remove the previous message since this has already been sent and is therefore unnecessary. However, I could not agree less. If you receive many emails you obviously cannot remember each individual email. This means that a 'threadless email' will not provide enough information and you will have to spend a frustratingly long time to find out the context of the email in order to deal with it. Leaving the thread might take a fraction longer in download time, but it will save the recipient much more time and frustration in looking for the related emails in their inbox!
Do not overuse Reply to All.
Only use Reply to All if you really need your message to be seen by each person who received the original message.
Do not forward chain letters.
Do not forward chain letters. We can safely say that all of them are hoaxes. Just delete the letters as soon as you receive them.
Do not request delivery and read receipts.
This will almost always annoy your recipient before he or she has even read your message. Besides, it usually does not work anyway since the recipient could have blocked that function, or his/her software might not support it, so what is the use of using it? If you want to know whether an email was received it is better to ask the recipient to let you know if it was received.
Do not ask to recall a message.
Biggest chances are that your message has already been delivered and read. A recall request would look very silly in that case wouldn't it? It is better just to send an email to say that you have made a mistake. This will look much more honest than trying to recall a message.
Do not use email to discuss confidential information.
Sending an email is like sending a postcard. If you don't want your email to be displayed on a bulletin board, don't send it. Moreover, never make any libelous, sexist or racially discriminating comments in emails, even if they are meant to be a joke.
Avoid using URGENT and IMPORTANT.
Even more so than the high-priority option, you must at all times try to avoid these types of words in an email or subject line. Only use this if it is a really, really urgent or important message.
Avoid long sentences.
Try to keep your sentences to a maximum of 15-20 words. Email is meant to be a quick medium and requires a different kind of writing than letters. Also take care not to send emails that are too long. If a person receives an email that looks like a dissertation, chances are that they will not even attempt to read it!
Don't send or forward emails containing libelous, defamatory, offensive, racist or obscene remarks.
By sending or even just forwarding one libelous, or offensive remark in an email, you and your company can face court cases resulting in multi-million dollar penalties.
Don't forward virus hoaxes and chain letters.
If you receive an email message warning you of a new unstoppable virus that will immediately delete everything from your computer, this is most probably a hoax. By forwarding hoaxes you use valuable bandwidth and sometimes virus hoaxes contain viruses themselves, by attaching a so-called file that will stop the dangerous virus. The same goes for chain letters that promise incredible riches or ask your help for a charitable cause. Even if the content seems to be bona fide, the senders are usually not. Since it is impossible to find out whether a chain letter is real or not, the best place for it is the recycle bin.

What is RAM and ROM ?

Random Access Memory (RAM) provides space for your computer to read and write data to be accessed by the CPU (central processing unit). When people refer to a computer's memory, they usually mean its RAM.If you add more RAM to your computer, you reduce the number of times your CPU must read data from your hard disk. This usually allows your computer to work considerably faster, as RAM is many times faster than a hard disk.
RAM is volatile, so data stored in RAM stays there only as long as your computer is running. As soon as you turn the computer off, the data stored in RAM disappears.When you turn your computer on again, your computer's boot firmware (called BIOS on a PC) uses instructions stored semi-permanently in ROM chips to read your operating system and related files from the disk and load them back into RAM.




Read Only Memory (ROM) is an acronym for Read-Only Memory. It refers to computer memory chips containing permanent or semi-permanent data. Unlike RAM, ROM is non-volatile; even after you turn off your computer, the contents of ROM will remain.


Almost every computer comes with a small amount of ROM containing the boot firmware. This consists of a few kilobytes of code that tell the computer what to do when it starts up, e.g., running hardware diagnostics and loading the operating system into RAM. On a PC, the boot firmware is called the BIOS.
Originally, ROM was actually read-only. To update the programs in ROM, you had to remove and physically replace your ROM chips. Contemporary versions of ROM allow some limited rewriting, so you can usually upgrade firmware such as the BIOS by using installation software.


Re-writable ROM chips include: 
  • PROMs (programmable read-only memory)
  • EPROMs (erasable read-only memory)
  • EEPROMs (electrically erasable programmable read-only memory)
