IT Sector May lose 50,000 Jobs
"...there would be 50,000 job losses (IT and BPO put together) over the next six months," Karthik Shekhar, general secretary of UNITES India, a politically neutral union of ITES professionals said.
The job loss in the IT and BPO sector in the country topped 10,000 in the September-December period, Shekar said.
While employees of medium-sized companies bore the brunt of job losses in the September-December period, it's going to be their counterparts in the big and small firms who would increasingly face the axe in the coming six months, he said.
UNITES India, affiliated to the global union United Network International, suggested that the companies in trouble could resort to salary and incentive cuts without trying to "squeeze" the staff, rather than adopting the "layoff path".
Employees are willing to take such cuts for 12-16 months till the demand picks up again, when such benefits should be restored to them.
Shekhar said senior officials of the industry had concurred with the figure of 10,000 job loses in September-December, stating that it accounted for "bottom five per cent of the performers".
Consultations with the union's counterparts in the US and UK suggested that slowdown would continue to hit the offshore sourcing space, he said.
He said factors like continued slowdown, likely "tax application" to companies outsourcing jobs under the new US regime and tightening in regard to H1B visas were among the key reasons cited for the acceleration in issue of pink slips.
சர்வதேச அளவில் ஏற்பட்டிருக்கும் பொருளாதார மந்த நிலை மேலும் மோசமடையும் பட்சத்தில் இந்தியாவில் 2009 ஆம் ஆண்டு ஜீன் மாதத்திற்குள் 50000க்கும் அதிகமான ஐடி, பிபிஓ ஊழியர்கள் வேலையிழக்கும் அபாயம் இருப்பதாக கணிப்பு ஒன்று தெரிவிக்கிறது.
பெரிய ஐடி நிறுவனங்கள் தங்களது பொருளாதார நெருக்கடி காரணமாக செலவினங்களை குறைக்கும் விதமாக ஊழியர்களுக்கு வழங்கி வந்த சலுகைகளை குறைத்து வந்தது. தற்போது ஏற்பட்டிருக்கும் மந்த நிலை நீடித்தால் கட்டாய விடுப்பு எடுக்கும் சொல்லும் நிறுவனங்கள் அடுத்து ஊழியர்களை நிரந்தர பணி நீக்கம் செய்யும் அபாயமும் ஏற்படலாம் என்ற கணிப்பு நிலவுகிறது. பெரிய நிறுவனங்கள் ஊழியர்களை பணிநீக்கம் செய்யாமல் தற்போது பல வழிகளில் செலவினங்களை குறைத்து வருகிறது. சர்வதேச அளவில் ஏற்பட்டிருக்கும் நெருக்கடி காரணமாக புதிய ப்ராஜக்ட் வர தவறினால் நிறுவனங்களுக்கு ஊழியர்களை பணியில் இருந்து நீக்குவதைத்தவிர வேறு முடிவு எடுக்க முடியாத சூழ்நிலை உருவாக வாய்ப்புகள் இருக்கிறது. பெரிய நிறுவனங்கள் ஒருபுறம் இருக்க சிறிய நிறுவனங்களின் நிலை மிகவும் மோசமடையும் நிலை உருவாகலாம். இதன் மூலம் பல்வேறு தொழில் நுட்ப பொறியாளர்கள் வேலையிழக்ககூடும். இதே போல பிபிஓ நிறுவனங்களுக்கும் இந்த ஆபத்து அதிகம் இருக்க வாய்ப்பு உள்ளது.
கடந்த 3 மாதங்களில் மட்டும் நாட்டில் ஐடி துறையில் மறைமுகமாகவும் நேர்முகமாகவும் 10000த்திற்கும் அதிகமானோர் வேலை இழந்துள்ளனர் என்பது தான் உண்மை. பல பெரிய நிறுவனங்களில் கூட ஊழியர்கள் அடுத்த ஒரு வருடத்திற்கு சம்பள உயர்வு மற்றும் போனஸ் இல்லாமலும் வேலை பார்க்க தயாராக இருப்பதாக சில நிறுவனத்தலைவர்களே தெரிவித்துள்ளனர். சம்பள குறைப்பு மற்றும் ஊதிய உயர்வு நிறுத்தம் போன்றவை ஊழியர்களை பெரிய அளவில் பாதிக்காது. ஐடி துறையை பொருத்தமட்டில் ஒரு நிறுவனத்தில் இருந்து மற்றொரு நிறுவனத்திற்கு இடம்பெயர்வது என்பது மிகவும் சாதாரணமான ஒன்று. ஆனால் இந்த பொருளாதார நெருக்கடி தருணத்தில் இது மிகவும் அசாத்தியமாக வாய்ப்புகள் உள்ளன. பல நிறுவனங்கள் தற்போது புதிதாக ஆட்களை எடுக்கும் பணியை அடியோடு நிறுத்தி வைத்துள்ளன. புதிய ஃக்ளைண்டுகள் கிடைக்கும் வரை ஆட்களை பெரிய நிறுவனங்கள் எடுக்க யோசிக்கின்றனர். 2001 ஆம் ஆண்டு இதே போன்ற சூழல் உருவாகி பின்னர் ஒரு ஆண்டுகள் கழித்து நிலை சீரானது. அதைவிட தற்போது நிலை மோசமாக செல்லவும் வாய்ப்புகள் உள்ளது. தன்னை ப்ராஜக்ட் களில் தக்கவைத்துக் கொள்ளாதவர்கள் உடனடியாக அடுத்த நிறுவனத்திற்கு மாறுவது நல்லது என்று உயர் அதிகாரிகள் ஊழியர்களிடம் நேரடியாகவே சொல்லும் கட்டாயத்திற்கு பலரும் தள்ளப்பட்டுள்ளனர். கிடைக்கும் பொழுது நல்ல வாய்ப்பையும் பயன்படுத்தி பாதுக்காப்பான கம்பெனிகளில் அமர்வதே தற்போதுள்ள நிலைமைக்கு முடிவாகும்.

ஐடி நிறுவனங்களில் கட்டாய விடுப்பு
சர்வதேச மந்தநிலை காரணமாக பல்வேறு ஐடி நிறுவனங்கள் பணி நீக்கம் மற்றும் செலவினங்களை குறைக்கும் முடிவில் இறங்கியுள்ளன. இவற்றில் ஊழியர்களுக்கான போக்குவரத்து வசதிகளை குறைப்பது, கட்டாய விடுப்பு, போனஸ் குறைப்பு, நிறுவனத்தில் பல்வேறு சலுகைகள் நிறுத்தம் என்று பலவிதங்களில் ஊழியர்களுக்கு நெருக்கடி கொடுத்து வருகிறது.
பெரிய ஐடி நிறுவனத்தில் வேலை என்றாலே பல்வேறு சலுகை, 6 மாதத்திற்கு ஒரு முறை ஊதிய உயர்வு, போனஸ், பார்ட்டி, டூர் என்று பல்வேறு வசதிகளை இளைஞர்கள் அனுபவித்து வந்த நிலை இனி இருக்காது என்று நிலை உருவாகியுள்ளது. தற்போது நிலவி வரும் பொருளாதார மந்த நிலை காரணமாக ஐடி நிறுவனங்கள் கொடுத்த வந்த சலுகைகளை கொஞ்சம் கொஞ்சமாக குறைத்து வருகிறது. ஆரம்ப கட்டத்தில் ஊழியர்கள் பயன்படுத்தி வந்த போக்குவரத்து வசதிகளை குறைத்து மிக குறைந்த தூரத்தில் இருப்பவர்கள் தாங்களாகவே நிறுவனம் வர வேண்டும் என்று உத்தரவு பிறப்பித்தது. தொடர்ந்து பல்வேறு வழிகளில் ஊழியர்களுக்கு ஆகும் செலவுகளை குறைத்து வருகின்றன. தற்போது பல்வேறு நிறுவனங்கள் ஊழியர்களை கட்டாய விடுப்பில் செல்லும் படி வற்புத்துக்கின்றன. ஊழியர்களுக்கு கொடுக்கப்படிருக்கும் விடுப்பு நாட்களுக்கு குறைவாக ஊழியர் விடுப்பு எடுத்திருக்கும் பட்சத்தில் அந்த நாட்களுக்கு நிறுவனம் சம்பளம் கொடுக்க வேண்டும். அத்தகைய மீதியுள்ள நாட்களை கட்டாய விடுப்பு எடுக்கும் படி நிறுவனங்கள் தற்போது நிர்பந்தனை செய்கின்றன. 2008 ஆண்டு முடியும் நேரத்தில் பல நிறுவனங்கள் ஊழியர்களை இரண்டு வார விடுப்பில் செல்லும் படி உத்தரவிட்டுள்ளது. இந்த விடுப்பு நாட்களுக்கு ஊதியம் கிடையாது. போனஸ், ஊதிய உயர்வு போன்றவற்றை அடுத்த ஆறு மாதங்களுக்கு பல நிறுவனங்கள் நிறுத்தி வைத்துள்ளது.
பெங்களூருவைச் சேர்ந்த அகிலண்ட் என்ற நிறுவனம் நாடு முழுவதும் 1800 ஊழியர்களை கொண்டுள்ளது. இந்நிறுவனம் தனது அனைத்து ஊழியர்களையும் ஒவ்வொரு மாதமும் 2 நாட்கள் கட்டாய விடுப்பில் செல்லும் படி உத்தரவிட்டுள்ளது. சென்னையிலும் பல ஐடி நிறுவனங்களில் பல ஊழியர்கள் வேலை வாய்ப்பை இழந்துள்ளனர். இந்த எண்ணிக்கை 500 தாண்டியுள்ளது. இந்த பணி நீக்கம் கொஞ்சம் கொஞ்சமாக நடைபெற்று வருகிறது. புதிதாக ப்ராஜக்ட் கிடைக்காத காரணத்தால் பல நிறுவனங்கள் ஆட்கள் சேர்ப்பதை தற்போது குறைத்துள்ளன. கட்டாய விடுப்பில் ஊழியர்கள் பலருக்கு விருப்பமில்லை என்றாலும், பலர் இதை எதிர்பார்த்து சந்தோசப்படுபவர்களும் உண்டு. குடும்பத்துடன் சில நாட்கள் சந்தோசமாக இருக்க முடியும் என்ற காரணமும் ஒன்றாக இருக்கிறது. இந்த நிலை இன்னும் சில மாதங்களுக்கு நீடிக்கவும் வாய்ப்புகள் இருக்கிறது. பெரிய நிறுவனங்கள் ஊழியர்களை நீக்காமல் கட்டாய விடுப்பு மூலம் சம்பள குறைப்பில் ஈடுபட்டால் ஊழியர்கள் ஏற்படும் பாதிப்பு அதிகபட்சம் குறையும் என்பதில் சந்தேகமில்லை.

Chinese mobiles get new life
This comes after a government directive asking all telcos to cut off mobile services to handsets that do not have an IMEI number by January 6, 2009. The government is likely to extend the deadline by another three months to March 31 even as some operators have sought that they be given time till July 2009.
IMEI is a unique 15-digit code that comes with every mobile and helps uniquely identify the handset. This number is reflected in the operator?s network whenever a call is made or received from any handset and therefore allows lawful interception of all calls. Mobile operators store these numbers in Equipment Identity Register (EIR) ? so if a handset is stolen, and its owner can provide the IMEI number to his operator to ensure that all calls from this device is barred.
In October the DoT asked telcos to install EIR so that calls without IMEI or with IMEI consisting of all zeroes are not processed. This followed investigations by security agencies looking into the bomb blasts in several Indian cities this year, which revealed that mobile phones used by terrorists did not bear valid IMEI numbers. Industry bodies representing Cellular Operators Association of India (COAI) and the Association of Unified Service Providers of India (AUSPI) will formally approach the DoT this week seeking an extension, the representatives in these told ET.
The industry will inform the DoT that customers who use these cheap Chinese handsets without IMEI numbers will not be able to afford a new handset. The industry therefore wants time to educate these customers to go in for a software update to get an unique identity number for their handsets. ?We need time to inform and educate the customer to have this software installed. This software is just being perfected and we will submit this solution to the DoT this week,? explained COAI?s director general TV Ramachandran.
These are genuine citizens who were ignorant about the IMEI number when they bought these handsets we have to give them an alternative. Customers will have to pay a small fee, maybe about Rs 100, for the software, but this is better than throwing away the handset,? he added.
Telcos are also set to tell the DoT that since the EIR equipment has to be imported and also tested extensively before it can be installed on the networks, the process cannot be completed by January 6. ?In some cases, the ordered equipment is yet to arrive, while in other cases, the equipment that has been obtained is being tested,? Mr Ramachandran added.

Nice One
"What's the difference?" Asked the puzzled father. "There's a big difference," replied the little girl. "If I hold your hand and something happens to me, chances are that I may let your hand go. But if you hold my hand, I know for sure that no matter what happens, you will never let my hand go."
In any relationship, the essence of trust is not in its bind, but in its bond.
So hold the hand of the person who loves you rather than expecting them to hold yours...
This message is too short......but carries a lot of Feelings.

SMS while chat in Google
A few weeks back, google ran into a few snags when we first started rolling this out, but starting today you can turn on text messaging for chat. Just click on Settings, and go to the Labs tab. Scroll down until you see "Text Messaging (SMS) in Chat" and select Enable and Save Changes.
We're just trying it out for cell phones in the United States right now, but you can send texts to your friends with US phone numbers from anywhere in the world. You can start by just typing a phone number or into the search box in the chat window on the left, then select "Send SMS." You can also select the contact you want to SMS first and then add their phone number.
Once you give us a name for that phone number, you'll be able to start chatting.
We'll save your friends' numbers in your Contacts, so next time you can just type their name in the chat box and select Send SMS.
On the receiving end, when you get a text message from Gmail on your phone, it will come from a number in the 406 area code. (The l33t folks in the crowd will note that this spells G0O.) You can reply to this text on your phone just like you'd reply to any other text. The reply gets routed back to our Gmail servers and shows up in your friend's Gmail chat window. Each of your friends' messages will come from a different 406 number so you can reply to any message and it will get back to the right person. Messages from the same person will always come from the same number, so you can even bookmark it in your phone.
If you get a message from somebody you don't want to chat with from your phone, just reply with the word BLOCK. If you don't want to get texts from anybody using Gmail, reply with the word STOP and we'll leave you alone. Keep in mind that all these text messages count as part of your regular mobile messaging plan and might incur fees. So unless you know your friends have unlimited text message plans, please be sensitive to their phone bills.

Computer Glossary
Accelerated Graphics Port is a type of expansion card slot on the mother board that is optimized to work with high performance video cards. They enable better viewing of 3D graphics and full motion video on your display.
BIOS
Basic Input Output System is code used when a PC first starts up. It contains configuration information about all the Input and Output devices in the PC so that the processor chip knows how to connect to and work with them.
BIT
This is binary digit and is the smallest piece of information a computer uses. A bit is always in one of two states, either 0 or 1, except for the tiny instant of time required to switch from one state to the other.
BYTE
A byte is eight bits. The data and instructions (code) that a CPU uses are coded into bytes. For example capital letter ‘A’ in ASCII (PC) code is byte 0100 0001. A lower case ‘a’ is byte 0110 0001.
BROWSER
Software on a computer used to request and display web pages from a Server.
CABLE MODEM
A type of modem that provides very high speed access to the Internet over the same cable that your cable TV service uses. Rates are asymmetric. This means that downloads are much faster than uploads. Typical download rates are 2 to 3 Mbps and uploads are in the 500Kbs range. This is blazing speed compared to a 56Kbps dial-up modem.
CACHE
Cache is a small fast SRAM type of memory. It prevents CPU slowdown, which happens when the CPU has to wait on slower devices like RAM memory and the hard drive. There are two levels of cache.
Level 1 or L1 cache is a small fast memory located on the same chip as the CPU. When files are first requested by the CPU they are read into the CPU from the hard drive and written into the L1 cache at the same time. When the CPU needs data again it checks the L1 cache and if it finds it there it gets it instantly. If not, it looks successively in the L2 cache, RAM and finally the hard drive, each of which is a little slower in delivering the data the CPU has requested.
If the CPU finds the data it wants in a cache it’s called a ‘hit’ and that’s good. If it doesn’t it’s called a ‘miss’ which makes the CPU wait a little longer to get the data or instruction it needs from one of the other slower devices.
This little bit of time saved by cache hits may not seem significant, but keep in mind that millions of accesses can be performed in a second. Every cache hit shaves time off the data access. Every cache miss adds time to the access. Cache misses lower performance and cache hits raise it!
Because level 2 or L2 cache is located in chips on the motherboard or on the board that holds the CPU it takes a little longer to access than the L1 cache.
L2 cache is becoming more important as it grows in size and performance. The L1 cache is very small because it is on the same chip as the large CPU. Due to it’s small size, chances are high that the CPU won’t find the data it needs there. An L1 cache miss causes the CPU to look in the L2 cache for the data.
The long and short of all this - If the data the CPU needs is not found in the L1 cache or L2 cache, the CPU must to wait to get it from the RAM memory. And if it isn’t in RAM, then the CPU goes on vacation for a number of milliseconds, which is a long time in the CPU world, while the data is retrieved from the hard drive.
CDD
Compact Disk Drive is a storage device that uses optics to read data from compact disks. CDDs that can read as well as write are very popular now.
CPU
The Central Processing Unit is a special chip that controls what happens in a PC. It fetches instructions and does high speed computations on data. It is somewhat like our brain in that it controls everything we do.
DIMM
Dual Inline Memory Module is a small printed circuit board that contains DRAM memory chips. When we say a PC has 256 MBytes of memory we are talking about the total capacity of all the DIMM modules installed in it.
Modern motherboard provide two to four sockets that accept DIMMs.
DOMAIN NAME
A unique name, formed with letters and numbers, that points to the actual numerical Internet address which locates a particular computer connected to the Internet. For instance, The Yahoo domain name points to Internet address 66.218.71.198.
So when you enter www.yahoo.com in your browser and click go, a special server called a domain name server intercepts and directs your request to the server located at address 66.218.71.198.
DRAM
Dynamic Random Access Memory is type of memory that must constantly be refreshed to retain it contents. It is used as the main memory in a PC and is packaged in DIMMs which plug into the motherboard.
DSL Modem
DSL stands Digital Subscriber Line. The DSL modem is a fairly new device, which allows high speed data to move between your PC and the telephone company on the same line that you use for your telephone calls. Yes. you can use your PC and talk over this line at the same time without interference!
How? Picture of a double-decker bridge with two levels. The traffic on the two levels does not interfere with each other even though it is the same bridge, right? Think of your phone call using the lower level and your PC using the upper level. Instead of being separated by different levels in space, the separation is done by your PC and voice each using a different carrier frequency, just like two different radio stations.
FAT16
FAT is the abbreviation for File Allocation Table. It is a table where the system keeps basic information for each file on your hard drive. The 16 indicates the number of bits used to address the hard drive. The largest partition FAT16 can access is 2MB. When used on a hard drive that is bigger than 2MB the drive space will be divided into a number of partitions.
For example a 10MB drive would be divided into five partitions of 2MB each. If the drive were the only one in the system the partitions would be called C:, D:, E:, F:, and G:.
FAT32
FAT is the abbreviation for File Allocation Table. It is a table where the system keeps basic information for each file on your hard drive. The 32 indicates the number of bits used to address the hard drive. The largest partition FAT32 can access is 2 Terabytes (two trillion bytes)! So far there are no hard drives I know of that begin to approach this size. Windows 98 was the first of the Windows OS to support this file structure.
FDD
Floppy Disk Drive is a device which provides a way for the PC to read and write floppy disks, which are a type of removable storage media. Floppy disks (3 1/2 inch) have a capacity of 1.44 Mbytes. When PCs first came out, floppy disks were 5 1/4 inch and held 720 Kbytes.
FIREWIRE
Firewire also known as IEEE 1394 or iLink is a very fast serial bus that runs at 400 Mbps. It competes directly against USB 2.0. Transmit and Receive data are carried on two separately-shielded twisted pair transmission lines. There are two other, rarely used, wires that provide power to remote devices.
Many newer computers have Firewire ports that are used to connect them to very fast external devices.
FTP
File Transfer Protocol is the method used by computers to send and receive files over the Internet.
HTML
Hyper Text Markup Language is the coding that is used to format web pages on Servers so that Browsers can display them.
HTTP
Hyper Text Transport Protocol is used by browsers and servers to facilitate the transport of web pages across the Internet.
HDD
Hard Disk Drive is a device that provides a large fixed typically (non removable) storage area. Some units today easily removable from the front of the PC. The capacity of HDDs has continued to increase. 40Gbyte drives are readily available and inexpensive. The HDDs used in the first PC had only 10Mbytes of storage.
IDE
Integrated Drive Electronics refers to the electronic control section of a Hard or Floppy Drive. This control section coordinates the electromechanical operation of the drive so that data can be written to and read from the spinning disk inside it. The motherboard connects to Drives over an IDE ribbon cable.
I/O
This means Input/Output. Input is data or signals that are fed into a device. Output is data or signals that a device drives to the outside. Some devices can do both, others are only one or the other.
ISA
Industry Standard Architecture refers to a type of expansion slot on the motherboard. It is the oldest of all expansion type slots and first appeared in the IBM PC XT. Thousands of expansion or add-on cards as they are also called, have been designed to plug into the ISA slot. The use of expansion cards vastly extends the function and capability of the PC.
MEMORY NON-VOLATILE
Memory is a device that retains information electronically. When power is removed the information is retained.
MEMORY VOLATILE
Memory is a device that retains information electronically. When power is removed the information is lost. The DRAM memory used in a PC is the volatile type.
OS
Operating Systems are the basic foundation or platform programs that allow you to load and run other programs on a PC. Windows 95 is an example of an Operating System.
PARALLEL PORT
The parallel port is a standard port on a PC and moves data out of the PC. One byte (eight bits in parallel) are sent out on 8 pins for each data transfer. Historically this port is connected to your printer. It also known as a ‘Centronics’ port, named after the manufacturer of the 38- pin connector first used on the parallel port.
PCI
Peripheral Component Interconnect refers to a type of expansion slot found on PC motherboards. It is a newer type of expansion slot than ISA, and many types of Add-On cards have been designed to use it.
RANDOM ACCESS
This refers to an access method. It means that any random location in a storage or memory device can be immediately accessed, with out going serially to get there. It’s like a cassette where your at the beginning and have to wind through everything on the tape to get to the last song! Compact Disks and PC Main memory are random access devices.
SERIAL ACCESS
This access method is found in audio or video cassettes. It means you can not access any location you choose to instantly. You might have to rewind or fast forward through lots of information you are not interested in to get to where you want to go.
SERIAL PORT
The serial port is standard port on a PC and can move data in and out of the PC. The serial port moves one bit on each data transfer. Many different types of devices connect to a PC through it.
SERVER
Software on a computer that serves web pages in response to requests from a Browser.
SIMM
Single Inline Memory Module is a small printed circuit board that contains DRAM memory. This is an older board style that was used in PCs before DIMMs were developed.
SRAM
Static Random Access Memory is type of memory that retains data without being refreshed. It is used in the cache memories of the PC.
TROJAN HORSE
Trojan horses are dangerous programs that appear like they might perform some useful task, or provide entertainment. This false appearance encourages people to run them. When they are run, they can damage files or place a virus on your computer.
Unlike a virus a Trojan horse does not replicate and spread. Since it isn’t a virus it can’t be repaired and must be erased from your computer.
USB
Universal Serial Bus is a high speed serial bus found on all newer PCs. Eventually it will obsolete the serial and parallel ports still found on most PCs.
USB specifies three data rates. Every USB port may not support the highest rate. If you buy a device with a USB port, make sure out find out which rates it does support.
Low speed - 1.5Mb/s
Full Speed - 12Mb/s
High Speed - 480 Mb/s
VIDEO ADAPTER
The video adapter is circuit board found in the PC or monitor that controls how data is converted and sent to the monitor for viewing.
Most displays and video adapters adhere to the Video Graphics Array (VGA) standard, which describes how data - the red, green, blue data streams - are passed from the computer to the display.
In addition, it defines the frame refresh rates in hertz and the number and width of horizontal lines, which in turn identifies the screen resolution in pixels.
Here are some of the video standards that have been used:
* CGA is 320 x 200 - developed in 1981 by IBM, no longer in use.
* EGA is 640 x 350 - developed in 1984 by IBM, no longer in use.
* VGA is 640 x 480 - developed in 1987 by IBM and still in use.
* Super VGA is 800 x 600.
* Extended Graphics Adapter, XGA is 1024 x 768.
* Super XGA is 1280 x 1024.
* Ultra XGA is 1600 x 1200.
VIRUS
It is a program designed to change the way your computer operates without your permission or knowledge. When a virus attaches itself to another file, it infects it. Any time you activate an infected file it can damage files, cause erratic system behavior, or display messages. Some system viruses are programmed specifically to corrupt programs, delete files, or erase your disk.
Viruses are inactive until you run an infected program, start your computer from a disk with infected system files, or open an infected file. Once a virus is active in memory it can infect any other programs, local or network, that you run.
Files infected with a virus can be inoculated (the virus is removed from the program).
WORM
Worms are a close cousin to viruses and Trojan Horses. Unlike a virus they don’t infect other programs. They do however make many copies of themselves in memory, which effectively consumes all your memory. This leaves no memory to run you regular programs. Your PC may behave very erratically, or just grind to a halt!
Some worms get into your e-mail list and e-mail themselves to everyone on your e-mail list without you knowledge. When each unsuspecting recipient opens such an e-mail, it broadcasts itself to everyone on their e-mail list. This is how worms rapidly travel throughout the Internet! Worms can not be repaired since they are not viruses. They must be erased from your computer, the sooner the better!

Nice one to follow
Monica's mother gave her a newly opened bank saving passbook. With Rs.1000 deposit amount.
Mother: 'Monica, take this passbook. Keep it as a record of your marriage life. When there's something happy and memorable happened in your new
life, put some money in. Write down what it's about next to the line. The more memorable the event is, the more money you can put in. I've done the
first one for you today. Do the others with Hitesh.When you look back after years, you can know how much happiness you've had.'
Monica shared this with Hitesh when getting home. They both thought it was a great idea and were anxious to know when the second deposit can be
made.
This was what they did after certain time:
- 7 Feb: Rs.100, first birthday celebration for Hitesh after marriage
- 1 Mar: Rs.300, salary raise for Monica
- 20 Mar: Rs.200, vacation trip to Bali
- 15 Apr: Rs.2000, Monica got pregnant
- 1 Jun: Rs.1000, Hitesh got promoted
..... and so on...
However, after years, they started fighting and arguing for trivial things.They didn't talk much. They regretted that they had married the most nasty people in the world.... no more love...Kind of typical nowadays, huh?
One day Monica talked to her Mother: 'Mom, we can't stand it anymore. We agree to divorce. I can't imagine how I decided to marry this guy!!!'
Mother: 'Sure, girl, that's no big deal. Just do whatever you want if you really can't stand it. But before that, do one thing first. Remember the saving passbook I gave you on your wedding day? Take out all money and spend it first. You shouldn't keep any record of such a poor marriage.'
Monica thought it was true. So she went to the bank, waiting at the queue and planning to cancel the account.
While she was waiting, she took a look at the passbook record. She looked, and looked, and looked. Then the memory of all the previous joy and happiness just came up her mind. Her eyes were then filled with tears. She left and went home.
When she was home, she handed the passbook to Hitesh, asked him to spend the money before getting divorce.
The next day, Hitesh gave the passbook back to Monica. She found a new deposit of Rs.5000. And a line next to the record: 'This is the day I notice
how much I've loved you thru out all these years. How much happiness you've brought me.' They hugged and cried, putting the passbook back to the safe.
Do you know how much money they had saved when they retired? I did not ask.I believe the money did not matter any more after they had gone thru all the good years in their life.
Moral is with yours.........

Salary cut for PM too...
The economic recession has hit politicians in Singapore, who are amongst the highest paid in the world. Their salaries will be cut by up to 19 per cent next year.
The Singapore prime minister, who earns more than the American President has set a precedent by taking a salary cut.
Lee Hsien Loong
Singapore Prime Minister Lee Hsien Loong salary of $2.46 million (Rs 123,079,932) is five times higher than that of the US president George W. Bush. His salary will be slashed to $1.99 million (Rs 99,505,769).
Singapore cut its growth forecast for a fourth time this year and the economy is expected to fall further in 2009.
Section 49–O of the Constitution
Did you know that there is a system in our constitution, as per the 1969 act, in section "49–O" that a person can go to the polling booth, confirm his identity, get his finger marked and convey the presiding election officer that he doesn't want to vote anyone!
Yes such a feature is available, but obviously these seemingly notorious leaders have never disclosed it. This is called "49–O".
Why should you go and say "I VOTE NOBODY"... because, in a ward, if a candidate wins, say by 123 votes, and that particular ward has received "49–O" votes more than 123, then that polling will be canceled and will have to be re–polled. Not only that, but the candidature of the contestants will be removed and they cannot contest the re–polling, since people had already expressed their decision on them. This would bring fear into parties and hence look for genuine candidates for their parties for election. This would change the way; of our whole political system... it is seemingly surprising why the election commission has not revealed such a feature to the public....
Please spread this news to as many as you know...Seems to be a wonderful weapon against corrupt parties in India... show your power, expressing your desire not to vote for anybody, is even more powerful than voting... so don't miss your chance. So either vote, or vote not to vote (vote 49–O) and pass this info on...
"Please forward this mail to as many as possible, so that we, the people of India, can really use this power to save our nation". Use your voting right for a better INDIA.
