What is the advantage and disadvantage of defragmentation?
Traditional hard drives arrange data on metal platters in a circular track similar to a vinyl record. The drive functions best when the data is arranged sequentially.
During the normal use of a computer files are created, change size, and are removed. When this happens small fragments of the files are created throughout the drive. This fragmentation of data is normal, but gradually degrades the speed of the hard drive.
To load a specific file the hard drive must read from many different areas and assemble the file in the system memory from the many small file fragments. Defragmentation is the process of re-organizing the hard drive data including the file fragments into a sequential order. Regular defragmentation will allow a hard drive to load files and programs faster than one which is not defragmented.
Newer solid state drives do not have the same performance loss issues from fragmentation that traditional hard drives do. Solid state drives should not be defragemented as it decreases the life of the drive.
What credentials are needed to work in computer science?
Computer engineers must have analytical skills and a strong attention to detail. A professional in this field also must have strong communication skills to lead a design team on a project. Computer engineers must be able to organize a project and have time-management skills to coordinate different areas of a project. The field of computers changes rapidly, which requires the computer engineer to continue pursuing education and training.
Advantages and disadvantages of digital jewellery?
THE ADVANTAGES ARE
1) IT PROVIDES SECURITY for example JAVA RING is used to lock or unlock doors or computers...as we use passwords and keys to lock our doors and computers we dont need to remember all those passwords and carry all those keys.SO java ring is designed to provide security
2)AS COMPUTING DEVICES are embedded it is not neccessary to carry CELLS r COMPUTERS...hence it is easy to carry everywhere
What does the motherboard hold?
The motherboard holds most of the essential circuitry needed for the computer. It contains the CPU, the chipset, the buses, the memory, voltage regulators, the BIOS, the CMOS battery, and various controllers. The motherboard may or may not have integrated graphics. If not, the machine will need a separate video card.
Why a computer might have more than one MAC Address?
The best way to understand a mac address is like a house.
If you add another networking device then you have another different mac address for it. Maybe like a neighbors house, just the other house is still on your street.
The IP address is like an apartment meaning 1 MAC address and several IP addresses(apartment a, b c and so on).
To have one networking device and more than one mac address would mean that virtual networking has been added and a quick system restore to the point prior to the date the new project started will return all configurations to normal, except there may be a few adjusments.
A computer might have more than one MAC address, if two or more NIC are installed, for example one wired and one wireless Ethernet card.
When was the first tablet PC made?
History of Touch Screen Technology
1960sHistorians consider the first touch screen to be a capacitive touch screen invented by E.A. Johnson at the Royal Radar Establishment, Malvern, UK, around 1965 - 1967. The inventor published a full description of touch screen technology for air traffic control in an article published in 1968. 1970sIn 1971, a "touch sensor" was developed by Doctor Sam Hurst (founder of Elographics) while he was an instructor at the University of Kentucky. This sensor called the "Elograph" was patented by The University of Kentucky Research Foundation. The "Elograph" was not transparent like modern touch screens, however, it was a significant milestone in touch screen technology. The Elograph was selected by Industrial Research as one of the 100 Most Significant New Technical Products of the Year 1973.In 1974, the first true touch screen incorporating a transparent surface came on the scene developed by Sam Hurst and Elographics. In 1977, Elographics developed and patented a resistive touch screen technology, the most popular touch screen technology in use today.
In 1977, Siemens Corporation financed an effort by Elographics to produce the first curved glass touch sensor interface, which became the first device to have the name "touch screen" attached to it. On February 24, 1994, the company officially changed its name from Elographics to Elo TouchSystems.

The very first complete TouchScreen Tablet can be defined when in 1994 the European Union initiated the 'OMI-NewsPAD' project (EP9252), requiring a consumer devise be developed for the receipt and consumption of electronically delivered news / newspapers and associated multi-media.
The NewsPad name and project goals were borrowed from and inspired by Arthur C. Clarke's 1965 screenplay and Stanley Kubrick's 1968 film: 2001: A Space Odyssey. Acorn Computers developed and delivered an ARM based touchscreen tablet computer for this program, branded the NewsPad. The device was supplied for the duration of the Barcelona based trial, which ended in 1997.
In 1996, The Webbook Company announced the first Internet-based tablet, then referred to as a Web Surfboard, that would run Java and utilize a RISC processor.
In 1999 Intel announced a Strong ARM based touch screen tablet computer under the name WebPAD, the tablet was later re-branded as the "Intel Web Tablet"
One early implementation of a Linux tablet was the ProGear by FrontPath. The ProGear used a Transmeta chip and a resistive digitizer. The ProGear initially came with a version of Slackware Linux, but could later be bought with Windows 98.

Where can you get an acting agent?
There are lots of agencies so all you have to do is send in your resume and headshot to as many agencies as you can! Keep trying until one of them ask for an interview.
It's best to ask The Screen Actors Guild for a list of SAG franchised agents to ensure that you are not going to be taken advantage of. If you are a youth (under age 22) your chances are better than if you are an adult, to be interviewed unless you are an adult with strong credits and experience. You can visit their website at https:/www.sag.org/home. I also suggest that you call each agent to make sure the address is correct and to ask if they are seeking actors your age RANGE and type. If so, get the person's name that you spoke with and send your submission to their attention. And remember, acting is more than a picture and resume! Study the craft wherever you can; school, a private class etc.. FYI: Kids do NOT have to have professional pictures to submit to agents, they aren't necessary until you audition for Casting Directors and they can can cost upwards of $200 plus the cost of duplicates, be prepared. - A Talent Manager
Hey, thanks so much, you really helped me :)
but do you know any acting agencies in Canada? my dream is to be an actor and a singer, and I'm not gonna give up, but i need an agent, and i live in Toronto Canada.
I'm not really familiar with agents in Canada so you might want to start with contacting the union there and ask them if they have a list of agents or just find out what their protocol is. Here's the link:

Best wishes!
OK, Thanks! I'm gonna try it. Thanks so much :)
You know, since I was a kid I have this dream. I used to sing in front of my grandparents and my aunt, and then they started to invite neighbors and other people, and when I was about 5 or 6 years old I started to love music, then I sang in marriages and stuff... And know, honestly, I think I'm a better actor than singer xD I don't think I'm a really good singer, but I love to act! I just wish I'd live in California or something. I lived in New York, but I never had the opportunity to go to show bizz.... Once again. Thanks so much for the answer. Byee :D
What kind of education is necessary for computer programmers?

How do I get my computer to remember my passwords?
To have your computer remember your passwords, you can use a password manager, which securely stores and autofills your credentials for various websites and applications. Many web browsers also offer built-in password management features; simply enable the option to save passwords when prompted after logging in to a site. Make sure to use a strong master password for your password manager or browser to ensure your data remains secure. Additionally, consider enabling two-factor authentication for added security.

Health and safety on the computer?
The internet is both safe and unsafe. It is only unsafe if you share personal information or download programs from untrusted sites. If you, your children, or your parents talk about the dangerous of the internet and you understand there are risks involved with things done on the internet then the internet is perfectly safe.
Remember, it's better to be safe than sorry.
Tell your children not to share the personal information like address, password, name, phone number etc. Be sure to keep an eye on your kids contacts, you never know who the person pretending to be another kid really is.
Internet shopping is very popular nowdays so be careful with internet payments. Invisible fraudsters can steal your real money if you share your credit card or bank account detail on untrusted websites which pretend to be a shop or something like that. Avoid using a credit card online. Use a prepaid card like paysafecard with online games, Skype etc.
