Is a microwave considered a computerized device?

No, a microwave isn't a computer. Most microwaves have a little (really little by modern standards) microprocessor chip in them to provide the "brainpower" to allow a user to program the appliance to perform a number of functions. A microprocessor is at the heart (it's the "brain") of a modern computer, but the microwave itself is not classified as one.

Four steps to protecet your computer from computer viruses?

1✦ Windows configuration-Virus spread can be stopped by disabling workstation
vulnerabilities, such as NetBIOS shares. NetBIOS is discussed in more
detail in the "Operating Issues" section of this chapter. A virus can exploit the
trust established between two users when a NetBIOS share is set up between
workstations.
2✦ User training and awareness-Most viruses (as well as worms and Trojan
horses) can be stopped in their tracks by an aware user.
3✦

One may also minimise the damage done by viruses by making regular backups of data (and the operating systems) on different media, that are either kept unconnected to the system (most of the time), read-only or not accessible for other reasons, such as using different file systems. This way, if data is lost through a virus, one can start again using the backup (which should preferably be recent).

4✦

One possibility on Windows Me, Windows XP and Windows Vista is a tool known as System Restore, which restores the registry and critical system files to a previous checkpoint. Often a virus will cause a system to hang, and a subsequent hard reboot will render a system restore point from the same day corrupt. Restore points from previous days should work provided the virus is not designed to corrupt the restore files or also exists in previous restore points.[24] Some viruses, however, disable system restore and other important tools such as Task Manager and Command Prompt. An example of a virus that does this is CiaDoor.

Why did you choose computer science b.tech?

Masters is always MORE and HIGH VALUE than a Bachelors.

It's really very Wrong to Compare BE / Btech to MCA, because, as you all know that BE / Btech is NOT Eligible for doing Ph.D (CS/IT), as MCA degree is Eligible for Ph.D

The Person, Who Compare BE / Btech to MCA should study about the Difference between a Bachelor's and a Master's Degree.

MCA is equivalent to ME (Computer Science and Engineering).

Particularly, MCA with Only B.Sc. (Computer Science) background is equivalent to ME (Computer Science and Engineering).

B.Sc. Computer Science (3 Yrs) + MCA (3 Yrs) = 6Years.

BE Computer Science (4 Yrs) + ME (2 Yrs) = 6 Years.

MCA and ME both are equal.

Companies are giving equal priority to both MCA and ME.

Two Master's Degrees, MCA and ME, are treated Same for jobs and there is no difference in the competence ratings.

Both MCA and ME (Computer Science and Engineering) Professional Degree courses, the contents of theory and practical syllabus are Same.

MCA and ME Degree holders are Equal to each other.

MCA - Master of Computer Applications.

ME - Master of Engineering (Computer Science and Engineering).

When Your Home PC Needs a Repair?

Computers are becoming as commonplace in homes as television sets. Many people use their home PC for many reasons. If your PC begins to lose performance or stops working altogether, then you may need to take it to a pc repair shop.

Make sure you backup all of your personal files before taking your computer into a pc repair shop. This is assuming that your PC is still working. By making a backup, you already have your important files. If the technician backsups your harddrive, then it is likely to cost you more money. Save his time and your money by doing your own backup.

Find the most reasonable pc repair shop by getting quotes. You will know the prices of the pc repair shop you select are fair. Doing a little homework about the costs of fixing your computer can ensure a good deal. If you know someone who has had their computer repaired, then ask them for a referral.

Ask the technician to diagnose your problem but not to replace any parts without your approval. You do not want a surprise on the bill. The pc tech should be able to give you an estimate of the cost to replace the component. You may opt to not have the part replaced. If the cost is too steep, then a new computer might be your best bet. If you are not afraid to open up your computer case, then you might want to replace the part.

Home pc repair can save you money and can be relatively simple. It all depends on what hardware needs to be replaced. Power supplies and memory sticks are the easiest components to replace. Physically replacing a harddrive is not that difficult but loading all of you software will take some time. Replacing the motherboard and CPU can be expensive and difficult.

If your pc needs to be repaired, then check into all of your options. If your computer is still under warranty, then get in contact with the manufacturer. Should you decide to take a technician, do some homework to find the best quote. Fixing your own pc might be a daunting task but with the right support can be the least inexpensive way to get your computer running properly.

Can computers learn?

Not in the sense that humans do. However computers can be programmed to develop their abilities and broaden their range of tasks. On the internet there are examples, like intelligent routers. Over a period of time they will build a database of other computers and routers that communicate with them. They can then become more efficient at sending data across the internet, by sending it to a router that it will know can pass it on a shorter or quicker route. This is just one of many examples of how computers can learn. But they have to be designed to do so, so the ultimate control still remains with those that design the hardware and software.
