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.

Nowadays, everyone has a computer and a connection to the internet. It has become a thing that no one could live without. Having a computer and a connection to the internet is like having what to eat every day. With its help we can watch movies, listen to music or watch videos online. We can connect with other people and we say that we socialize. We can create for us a virtual society where no one know what the other person looks like, we don’t know what we do for a living or what kind of people we are. Online we can be anyone we want.

What some of us don’t know is that some sites are dangerous. You can find anything on the internet. Games, music, pictures videos and we can even buy things online and we don’t have to go to a store or just leave the house. There are sites that can freeze our computers. All it takes is one click and it is done. When you search something online you don’t always know on which website enter to look for what you are interested. There are some suggestions but we don’t know exactly if that site is 100% safe. There are many viruses online and they are very dangerous. It takes just one click and you can lose all the information you have on your computer. That is why it is important that you have a good antivirus and a firewall.



There are free online scanners that help you detect if you have viruses on your computer. But this doesn’t help get rid of them. You have to buy an antivirus from a known company to make sure that your computer is safe. If you use an online antivirus you can see if your computer is infected. After you scan your hardware, different colors appear that let you know which the most infected areas of your computer are and which are critical. This means you have to remove them from your computer.



When we click on a website, we don’t always know if it is secure. That is why when you search for something in a search engine, the application you use (Mozzilla, Google Chrome or Internet Explorer) shows you the health of the sites it finds. This is why it is very important to be up to date with all upgrades for any application you have on your computer. It is not too difficult to be up to date, especially because these applications are free of charge and all you have to do is just click help for updates. If a site has a very small health, it is definitely not a good idea to click it. If you think you need something from that website you should probably search for another because it obvious there is a problem with that one.

The storage of data on different devices can be magnetic, optic or electric. A storage device can be anything that records or storage data in different forms. This type of definition on data storage devices includes a variety of elements and methods, like memory cards, audio or video cassettes, hard drives or perforated cards. Any of these devices can store data. The way of recording data is different for all of these.

The methods of recording the information you need later are digital inscription or analog. At first there were used only analog methods. For example, the recording of sounds on cassettes or the recording of video signals on video cassettes was very useful. Computer devices have evolved so digital methods of storing data have evolved too. Today they are necessary and very popular.



A computer has two categories of data storage devices: internal and external memory. The external memory of a computer is composed of all storing components portable or semi portable. The portable storing devices are easy to detach and easy to replace. Some of these storage devices are: flash drives, CD ROMs, DVD ROMs or memory cards. Not long ago, hard drives were known as semi portable components.

When smaller laptops known as notebooks appeared they had to make an adjustment to increase the capacity of staring data without removing any component from the computer and so external hard drives were created. As we said before, the storage of data can be magnetic, optic or electric. The magnetic storage is for hard drives and it was for floppy disks too.

Nowadays, the floppy disks disappeared and were replaced by electrical and optical storage devices. The electrical storage is made on flash disks. Flash drives have become very popular because they are very easy to use, they last long and they have a big storage capacity. They connect to the computer or a mobile phone trough a USB. The process that stores data on a CD or DVD is called optical storage. There is a laser in the computer that writes the data we need or that reads the data that was written on it.



External memory comes in handy when you have a computer and cell phone for example. The cell phone has some internal memory but if we have pictures, music or even movies on it we might need to empty some space for other things to store on our phone. So, what do we do? We use the computer to store the data from the phone. This way we free space from the phone and we can use it to other things on it. If you want to get a memory stick you need to pay attention to some details.

It has to be compatible with what you need it for, the transfer speed must be very good and you can install different programs that allow even a faster speed of transfer for data.

Not everyone is interested in this domain but it is good to know how you can create a backup of your pictures, music or movies. If someone asks you to give him something you have on your computer you just use a flash drive. You copy it on the flash drive and you give it to him.

Computers are highly important these days because they are the ones that offer their users countless possibilities. In these days, all of us depend on a computer a lot and we can even say that they are vital electronic devices that have to be used day by day for doing certain activities.

PCs can be found in the homes of every family and most members of the family use them daily for doing diverse things. Because the technology that is found inside these devices is in a continuous development, many people use to change their computers after a certain period of time or more easily upgrade them. By doing these activities they have to go to a special store in order to buy their desired components. From my point of view, all the components, both internal and external are highly important because they all are made for doing certain things. All of them can be purchased with needed b many places such as city stores. The electronic stores that are found in every city that sell them are quite numerous and you can buy them without any kind of problem.

The HDD plays a vital role in the good functioning of every PC because it is the one that permits storing diverse information like Microsoft Office documents, pictures, games, movies, applications and others. You can read here all about the hardware of a computer and I am sure that many things you will find interesting. The history of computer storage devices is quite unknown and not many PC users how it evolved. Well, you will find on this website the hole history of computer storage devices and I am sure that you will find it very interesting especially that it is explained also in pictures. You will see how technology evolved in 30 years and I bet that you will be at least impressed.



All in all, knowing the history of computer storage devices is great because you manage to know how technology advanced in about 30 years and you knowing the first storage devices is from my point of view cool and very interesting.
