How do you take off toolbars on your computer?
The most thorough way to do this is to locate the toolbar in question in the Add / Remove Programs applet (in Windows XP and earlier) or the Programs and Features applet (in Windows Vista and later) in Control Panel, and select Uninstall there. If the toolbar is built properly, that will remove it.
Not all toolbars are honest, however; some do not provide an uninstall method. If the toolbar does not provide an uninstall entry, it may have to be removed by a spyware or adware removal tool; or a computer professional may have to be called in.
If you want to try to remove a toolbar that resists being removed correctly, two tools that seem suited to the job are AdAware and Spybot Search and Destroy.
Note: This editor uses both of the tools mentioned above, but has no financial interest in either of them.

Is there anything you can get to give your computer more GHz?
If by "get more GHz" you mean speed up your processor, it's a lot harder to do on a laptop. You could overclock it, but most laptops have very few options for overclocking and overheat easily due to the excess heat created. If you need a faster computer, I recommend buying a desktop (which you can actually overclock) or upgrading to a better laptop.
Here is a great overclocking guide:

What is the Role of computer in science and engineering?

What is the definition of a digital computer?
it deals with logic 1 and logic o where logic 1 is represented by a voltage and the other is also represented by a voltage
There are both digital and analog electronic devices. Digital devices use a binary input - that is, the electrical signals they use to perform functions are in one of two states - a predetermined high or low voltage threshold (sometimes referred to as "on" or "off, 1 or 0 or True or False).
Compare that to analog devices which receive electrical input that use either a constant, direct current, such as that supplied by a battery without any conversion process, or from an alternating current, such as that supplied by your home outlet. The alternating current rises and falls gradually through a series of different states (voltages), rather than the abrupt on/off states that digital equipment requires.
In reality, many electronic devices use a combination of both analog and digital input to accomplish a variety of tasks. For instance, your computer's fan may use an analog signal, while it's processor relies on digital signals to produce output.
What are the possible consequences of computer hacking?
A lot of bad things could happen. For example, the hacker could gain access to personal information like credit-card numbers, social security numbers, etc. You could also get a number of viruses that could render your computer unusable. If you really think your computer has been hacked, you should take it to a repair shop immediately.
This is very rare however, it's more likely that you just have a virus on your computer and it is extracting information from your hard-drive. A hacker is someone who actively take information from your computer and they can be taken to jail for doing so.

Why is it important to take breaks from looking at the computer screen?
Yes it is good but it is all up to you. unless you live by your parents rules (that sucks). Take a 5-10 min break every 2 hours. But for some reason people say take a 15 min break every halve hour. So have fun NOT wasting your time playing games on the computer. :) And it is good to take a break from the computer is because your eyes will get sore. But I am used to spending long lengths of time using a computer i can go for at least 9 hours with out taking a break. but i still have to go to the bathroom. soooo..... going to the bathroom can count as a break. and if your eyes get sore just wash your face with cold water. that should get some moisture into your eyes to make them feel better.

Why is it important to be safe?
As you know, the internet is full of hackers, viruses, spyware and malware. If you wasnt protected, you will get all of these. As its categorized in the Child Internet Safety too, I will tell you the common issues about child safety on the web. Basically, spyware will create pop ups which will display all over your desktop. The pop ups are not nice, they will contain rude images, videos and sounds. The only way to block these out is to get the right protection. Also, you will have to be careful where the child is looking and what the child is doing, for example; chatting sites like facebook are a big problem. The child might be chatting to a stranger?. You can get softwares to filter out all the chat, dating, porn and any other sites you dont want your child to look, you can do this in your firewall also :).
Do you have to hook the router up to a computer?
No - a router can connect to a computer, another router, a switch, a hub, a bridge or a modem. If you are connecting to the Internet via DSL or cable company you will need a modem/router to connect to them. You then attach your computer (or computers) to that router.
Routers are useful because they make decisions about which way a packet of data goes - this network or this network? If you have one network that doesn't go anywhere (connect to the Internet or another network) a router is of no use to you and a switch generally does wonderfully and is cheaper than a router.
