Computers

Computers do not use waves, they use a digital signal. Unlike a wave, a digital signal is composed of a sequences of high and low voltages. These voltages remain at a constant voltages for both high and low. For example, a high voltage may be 5v while a low voltage may be -5v. Computers are designed to interpret these as 1s and 0s, or binary - the language of computers.

The physical components that make ups computer system are the Central Processing Unit (CPU), the Hard Drive (data storage), the Motherboard, the Optical/Disc drives (CD readers and the like), the Power Supply Unit (PSU), the external parts (the case, speakers, monitor, mouse, keyboard, etc.) and numerous fans and cables inside the computer.

Once the CPU has been allocated to a process, the process keeps the CPU until it releases the CPU either by terminating or by switching to the waiting state. In a general purpose computer system, users share the CPU and care about system responsiveness. If the system uses non-preemptive scheduling, some users may sit before the monitor for several hours without doing anything other than waiting for the set of processes in front of them in the system queue to finish. So, strictly non-preemptive scheduling is unlikely to be used in a general purpose computer system.

There are several reasons why the computer got frozen/ not working or hanging up. One of possible reasons are 1.virus -some of this are deleting files and reduce the performance of the computer. Once the virus is loaded in the main memory it's affect the speed in accessing data in the computer.2.Worm-worms,its occupy the disk space that sometimes if the disk space is occupied it slow down the speed of the computer.3. Users-sometimes the way we use can cause computer to hang or get frozen. Multitasking or opening of a 1 software at the same time can slow down the computer operations.We can compare it to ourselves eating while mouth is full is not good,we chew the food while putting another food while our mouth is full.

Compressed file means files with rar/zip extension .There are some reasons for compressing files. Compressed files can not be affected by virus. It can save disc space. You can use it if you want to back up some folders/files.

i guess there are pros and cons to this.

pro being data (say a document for example) can be sent straight over the internet, instant copies can be made and modified, printed etc. its an overall win for convenience and professionalism.

and of course a con being there is always the chance (however unlikely) that your computer may die and you'll lose everything. however there are steps you can take such as keeping another virtual copy on an external drive or another computer.

i personally think the option on keeping data virtual is a win.

hope this helped.

Well there are many ways to buy a decent good PC or laptop, If i were you depending on what you are willing to spend. The best options would be eBay or amazon, If you are stuggling to find a cheap PC or laptop go to a local 2nd hand shop and at a last resort you could go to a local electrical store and look for sales. =D

hubs, switches or routers.

The CPU is also called the Central Processing Unit, which is exactly what it does. It runs all of the processes for every little program running on your computer. It decides which system resources go to which program, and closes and opens programs. Without a CPU, the computer is useless, as it even controls the Operating System. You can view the CPU's current processes by open your Task Manager. To do this is different on different operating systems, so you will need to look that up on Google.

hello

No. The smallest practical unit of information is the bit - which is what you get when you can have two choices, often called "yes/no", "true/false", or "one/zero". In theory, a byte can have different sizes, but it is normally standardized as 8 bits. It is the smallest amount of computer memory that can be directly addressed.

Some examples of data storage devices include:

* Hard drives * CD, DVD, and Blu-Ray drives

* Floppy drives * Zip drives * USB Flash drives * CompactFlash cards * SD cards * Tape drives

Hi guys, sorry this isn't the answer, it's my question but i thought i'd put a bit more info on it to help anyone work out the problem.

I have a Dell Inspiron 640m laptop, it's pretty old but works okay and recently it won't go past a blue screen that appears saying:

A problem has been detected and windows has been shut down to prevent damage to your computer.

If this is the first time you've seen this stop error screen, restart your computer. If this screem appears again follow these steps:

Disable or uninstall any anti virus, disk defragmentation or backup utilities. Check you hard drive configuration, and check for any updated drivers. Run CHKDSK /F to check for hard drive corruption, and then restart your computer.

Technical information:

*** STOP: 0x00000024 (0x00190203, 0x82EE52C0, 0x0000102, 0x00000000)

So yeah any info or help will be greatly appreciated!

Cheers,

PS. if you could use English instead of computer language that would be great :)

Refurbished computers (both laptop and desktop) are commonly available on Amazon.com. There is so much variety on their site, you are primed to get a great deal. Another solid option is going direct from the manufacturer. In many instances, there are computers they personally refurbish and sell at a fraction of the cost.

Locating computers for sale is not difficult in this day and age. More than a handful of models are available at any given time - new and used. With that in mind, an individual should be able to find something within their price range. A small fortune is not required to purchase a laptop or desktop computer that will get the job done. Millions of people own these machines nowadays, so they could not be easier to find. However, making a decision on any particular option is not as simple.

A potential buyer must first figure out what type of computer they are going to need. Obviously, these devices are designed to do different things. For instance, one machine might be optimized for gaming with a great video and graphics card. Another one might be more suitable for business applications with better security features and whatnot. No computers are completely identical under the surface. In any case, the chances of buying the right device increase once a person figures out exactly what they require.

From there, it is wise to look at a few models of computers for sale at a local store or online. Failure to do some basic research can lead to plenty of problems later on. Visiting an electronics store allows someone to test out the models that they are taking into consideration. Undoubtedly, this is the best course of action to take so that an individual can wind up with the right computer. Nobody wants to purchase the wrong thing and regret it later on. In reality, that is exactly what will happen for those that do not take enough time.

In the end, it could not be any easier to find computers for sale. That does not mean that a person should take the whole process lightly. Research and caution are necessary to end up with the best buy possible. Sadly, too many people rush through the process and end up with a machine that does not suit their needs or tastes. Of course, that is a completely avoidable outcome. All a person needs to do is tread carefully and consider every variable.

To type on a computer, you must lift up your finger then pressing it down on to a letter displayed on the keyboard, After you get the hang of it you use those letters to make complete words and sentences, paragraphs, etc. and then you can type!
