If you have a computer it is always a good thing to make copies of the things you are interested the most. If you have some important files or pictures you should use any kind of storage device to put them. Sometimes it happens that our computer breaks and there is no way of retrieving the data you had and that is why you need to think in advance and take action. You can buy a CD, DVD or a memory stick and you can store anything you want on them.

Electronic data storages require electric impulses to process the information you need to backup. For example you can create a backup to your files on a CD. The moment you shut down your computer the data that is on the CD isn’t lost. It stays there and you can use it anytime you want. There are electronic devices that lose their data when they have no electric power. For example, the RAM memory of a computer is a storage device for the computer but the moment the computer is shut down it loses the information. When you open it again you have to take from the beginning.



Having a computer is critical nowadays. But people abuse it. When you have many data on your computer you should definitely clear some space from your hard drive. It is difficult to decide which data to put on CDs or DVDs but it is crucial that you do it. You must know that electronic storage isn’t infinite. At some point it remains with no space. Then you are forced to clear some space and it will so much that you will never be able de decide which to erase or which to write it o a CD or a DVD.

The first computers that were built were very expensive and very large. The size of the first computer was like a medium room. The only thing it did was calculations. These calculations were very complicated and they were used by the military. Nowadays, the computer is used in all the domains. Now you can do anything on it: you can play games on it, you can listen to music, you can movies, you can talk to other people and also you can see them if you have a web cam, you can do designs and you can keep all your important data on it.



It is a good thing that technology advances especially computer technology. It is very well related to the other domains. Having a computer and a connection to the internet is like you don’t need a cell phone any more. You can talk to anyone you want from anywhere in the world. Also, if you have a web cam you can see the person you are talking too. Besides, you can make a lot of friends online and you can play games without leaving the house.

In conclusion, if you have some important data on your computer that you definitely want to keep you should probably create a copy by using a CD, a DVD or a memory stick because in some cases when your computer breaks you won’t be able to recover the information you need.

Nowadays the computer industry is very advanced. The companies invented different components for a computer that help us keep our data intact. If we want to create a backup to what wee need like pictures, music or movies it is very easy. There are CDs, DVDs or flash drives. They are easy to use and they are affordable by anyone.

An interesting component of the computer or better said an accessory is the memory stick. It is very interesting and very practical. You can store any type of data on it and you can even install an operating system from it. Some time ago there were the floppy disks. They were critical for a computer because there was no other way to install an operating system on you computer. Now, there are CDs or DVDs that store such operating systems like Windows, MAC or Linux.



It happens sometimes that a computer doesn’t recognize removable storage. If that happens the first thing that comes in mind to do is unplug it and plug it back in. Sometimes the computer just needs a little more time to figure out the type of the stick you plugged in the computer and see what you have on it. In case you have an older computer you may have a problem. If the stick is very new he may not recognize it. And now you really have a problem. A solution could be transferring your data on a CD and keep it there.

Newer versions that have been upgraded might not be supported by older computers. So, if the computer doesn’t recognize removable storage you may have a problem. Removable storage is a new concept nowadays. It still has its flaws and the companies try to make it compatible with any type of computer. The thing is if your computer doesn’t recognize removable storage it is probably a good idea to upgrade it. You need to advance as well once with the technology.



The hard drive is a removable storage device. If you access data from the disk it might take some time sometimes but the thing is that disks are cheaper than RAM memory. You keep all your data on a removable storage but this isn’t always the best thing to do. If you have important stuff on your computer it is bets if you make a backup and keep it somewhere safe. Disk drives are very advanced but like any other component in the technology industry sometimes it can break. And if you have really important data on it you may never recover it.

Everyone one of us has a computer and any one of us had a problem with it at some point. The important thing is that we stay in touch with technology because it could happen that we lose some important data on our computer. If you don’t know what to do just ask a friend for help or you can ask for a professional to help for a small fee.

Nowadays having a computer in your home is crucial. It keeps us connected with everything in the world. If you have a computer you don’t need other things like a phone, a cell phone or a TV. If you want to watch TV you go online and you search free TV. Networks have online all the programs you watch on a TV. If you want to talk to a friend, you login into Yahoo or other application like this one and you can talk to anyone anywhere in the world. And most important it is free of charge. Also, you can get a video reception if you have a web cam.

Today, laptops have become very popular. They are easy to use just like a normal computer but the important thing is that they are very practical. They don’t require that much space to deposit and you don’t have to worry that you don’t have the necessary space for it. Also, it is very useful when you go on a ride because it has a battery that allows you to use it for 3 or 4 hours depending on the model.



But, if you are a traditional man and you want a normal computer you can go and buy one. Some people prefer to buy a computer that is whole from the beginning. It has warranty for the whole thing and if it breaks something you can go to the store’s service where you bought it from. It is not that much of a trouble for you and you don’t really know what it has inside. If you break the warranty and you want to upgrade a component you have to bring to the service, pay a fee and they will upgrade it for you.

For those who don’t know you can build a computer with custom hardware. You just have to buy the components separately. Of course, you shouldn’t do this on your own if you don’t know which the best components are. You have to know of course if the components you buy are compatible with each other and if you will have an advanced computer. For this you need a friend who knows about computers or if you really are interested in an advanced computer you can hire someone who does.



So, if you want to build a computer with custom hardware you will need: the main board which is the most important component because this makes the connections between the rest of the components; the video card which allows you to watch 3D movies if you are interested in this kind of movies and play advanced games; the RAM memory which is important because it determines the speed of your computer; the processor is important as well because it determines the computer’s frequency; at last but not least you have to buy a monitor. This one is important too because otherwise we won’t be able to see anything. These are the major components of a computer and if you really want an advanced one you should consider asking someone for help if you are not into this type of technology. In any case, what you buy today and is considered to be very advanced, tomorrow it might be less advanced. And this is because technology evolves and companies upgrade every day the components making them better and better. This is the way things evolve and we must evolve with them.

A video card is also known as a video adapter. The function of a video card is too generate images that we can see on a screen. A lot of video cards have additional features such as accelerating 3D scenes. Others can be connected to different screens at the same time. The most important thing that a video card is made for is games.

When we buy a computer we want the best video card there is. If we use the computer only for music, pictures or talk to people online we don’t need a very advanced video card. If the main board has one incorporated it is as good as it gets. But, if we want to play a new game, an upgraded version of a game that we played before we definitely need an advanced video card.

The first video card ever made was back in 1981. It worked only in text mode but back then there weren’t movies made like today will all kind of special effects or 3D movies or too advanced computer games. It had 80 columns and 25 rows on the screen. The first video card was a MDA, meaning Monochrome Display Adapter. Trough the years the companies developed more and more advanced video cards. The VGA video cards were very quickly accepted on the market. This way, the others companies that made video cards were forced to make improvements to their video cards too.


In 1995 the number of people that bought a 2D/3D video card exploded. Everyone was impressed with what it can offer. Movies were like in the cinema and the games were very real. Today, the battle for dominancy is between ATI and NVIDIA and they control 90% of all the market. Smaller producers are forced to sell their products on a smaller scale.

A modern video card is made of circuits on which are mounted the components. These components are: the GPU, meaning the graphic processing unit, used for graphic acceleration required for the 3D pictures; the BIOS, which is the main program of the video card and it is usually hidden; this BIOS is the key component of the video card because it makes the connection between all the other components and between the video card and the computer. It offers instructions like information about the memory calendar, operation speed, RAM memory and other types of information.



The video memory is another component of the video card. Capacity of this component may vary between 128MB and 4GB but there are few video cards that have over 1 GB. The video memory can be used for other things like the picture on the screen or the Z-buffer that is connected to the 3D technology.

The bottom line is that technology evolves. Companies try to make better and better products for us to buy. Video cards are for those who love movies in 3D and games. Nowadays, there is technology that makes you believe that you are a part of the movie you see or that you are actually in a game. It creates a virtual world in which no one can see you but you can see everyone else.

Computer storage is a device that helps us keep the information wee need. There are different computer storages that we can refer to: hard disk, flash drives, CDs, DVDs an others. All of these advanced very much in the past years and they still advance. The computer technology is a branch of technology that advances very fast and no matter how hard we try to keep up it is a bit difficult. There are always changes made to computers and the companies try to make them more attractive for us to buy. I believe their best invention is the laptop. You can carry it with you anywhere you go and it is very practical. It doesn’t use that mush space to deposit and you don’t have to be afraid that you don’t have the necessary space to put it.

An interesting component or better said accessory to a computer is the flash drive. At first there was the floppy disk. It was a component that never missed from a computer. Now, the companies don’t even bother of attaching it to the main unit of the computer because it has no longer a use. It was used to install an operation system on the computer. Now, there are CD ROMs that help us do this. The flash drive is a very popular accessory. It is like a smaller hard drive. You can store different data on it like music, pictures, videos or anything else you might need.



The first computer was very big. They said that the main unit was the size of a medium room. The only thing that that unit did was calculations. Year after year, the companies tried to make it smaller and smaller. And we all see that they succeeded. All the components of a computer are made smaller and smaller in size and weight but very capable. In this case, size really doesn’t matter. If you look to a computer and you see it is smaller than others is doesn’t mean it is less advances. Even the smaller computer can be the most advanced device you see in a store.

Today, you can connect a cell phone to a computer. This wasn’t possible in the past. Now all you need is a cable. Trough this cable you can copy from the cell phone to the computer music, movies or pictures or the other way around. It also charges the battery of the cell phone meaning that the cable works as a charger. This is a very reliable thing because the cell phone charges when it is connected to the computer while you do the transactions you want. Of course, it is important to have a cable for your cell phone because in case you forget your charger at home and you have with you the cable from the phone you don’t enter the situation where you need to find a charger before your cell phone battery dies.



In conclusion, trough the years companies try to upgrade computers. Every second that passes means that another thing is discovered in technology. They try to find different things to invent and to create. It is a good thing that there is so much competition between the companies because this way the prices can sometimes be very low. For example, they recently invented the cheapest laptop and it cost only 35 dollars. The price can even go lower in case the company deals with the marketers.
