How Video Games Systems Work

December 4, 2011, 3:20 pm

Individuals have always liked to play games after work or school and that has not changed today, but what has altered is the complexity of the item supplying the game. Before the Second World War, the most complicated popular games were almost certainly chess and Bridge and most kids played football. Nothing complicated in the games systems there.

In the Fifties and Sixties, the pinball machine was probably the most complicated device available but it was too expensive for most people to have in their homes.

However, despite the fact that they were complicated (for the day), they were made up of transistors, diodes, springs, light bulbs and rubber bands. You could see the moving parts and the scorch marks where something had burned out.

However, since the Seventies, the machines that supply our distraction have no moving pieces except perhaps a joystick and hardly anyone has a clue what happens inside that appropriately-named Xbox and they have no clue about repairing it themselves.

So what does go on inside that mysterious video games machine and how can it produce so much enjoyment for so many without a single rubber band or spring to be seen?

First, there is a big difference between a games computer and a video game console. A normal office computer to be used for routine admin and the Web does not have to be anything extraordinary, but a games computer has to have more RAM, the fastest CPU and the fastest graphics card to be any use.

A games console strives to emulate a games computer, but strips out any component that is not absolutely vital to play games. The distinction is becoming more and more blurred as gamers demand more powerful interactive, multi-player games that they can use over the Internet while chatting with their mates in chat rooms, which are frequently dedicated to the game in hand.

Games machines will have a cut-down operating system, because it does not have to be ‘ready for anything’, so games load far more quickly. They are typically stronger than a computer too, because manufacturers realize that some gamers get carried away.

They may even get more waterproof than your average laptop. They are often easier to connect to a screen or home movie theatre system as well because numerous crowd who use them are not technically minded, but may would like to take the console to a friend’s house.

The insides of the games console have not changed a lot since the Ataris of the Eighties. That is to say the degree of sophistication has, but the names for the components have not. A games console still has a CPU, RAM, audio out, video out, a user control interface, a power supply and a way of loading the game. The sole new things are the DVD and Net connections

There is no question that modern gaming machines are a lot better than the old Ataris of 30 years ago, but the technology is merely better, not different, which goes to show either how imaginative Atari were or contemporary console makers are not.

Owen Jones, the writer of this piece, writes on many subjects, but is currently concerned with Mortal Kombat Trophies. If you have an interest in gaming, please go over to our web site now at Mortal Kombat 4.

What Are Asset Management Techniques?

November 26, 2011, 4:47 pm

How does one go about taking care of one’s property – one’s worldly possessions? Well, the majority of people put their money in the bank, put the jewellery in a safe and insure the rest. But insurance is not really taking care of your possessions, is it? It is taking care of yourself so that you do not have renew them with your own money.

In the old days, and even now, I suppose in some countries, you would employ a boy to watch over your sheep or cattle or bring them in at night for fear of lions, wolves or thieves. These were an early kind of security guard and indeed wealthy people had and frequently still do have private body guards.

What if you had a large office with a hundred laptop computers – laptops because employees had to do field work too? How would you keep track on all those? A car is another good case in point and construction site machinery is being stolen all the time even from under the noses of (or with the help of) private security firms.

So what can you do? Get dogs? That works usually, but they can be poisoned. Install video cameras and passive infra-red movement sensors connected to a control centre? That works and a lot of firms and private houses have it, but it is very expensive.

As a low-priced alternative, the police were giving out free pens in the UK, which wrote in invisible ink. The idea was to put your postcode and house number. This ink became visible under a certain kind of light. That is fine if you have a suspect or found goods.

Bar codes are not practical, the pen is better. It all comes back to insurance or surveillance.

However, there is another technique that is becoming affordable. The concept has been around for about 85 years, but it was too expensive to use on anything less significant than an airplane or a battle tank.

I am talking about radio frequency identification or RFID for short. The idea is the same one that aircraft have been using since during the Second World War – a transponder emits precoded information in response to a demand from an RF reader.

Information regarding ownership and details of what the item is can be written to an RFID chip also called a tag and the tag can then be glued inside the object that it is to protect.

There are two varieties of tag: the passive and the active. Passive tags will only reply if information is requested by a reader, whereas an active tag is always broadcasting.

Many entrepreneurs use RFID tagging to keep track of their goods. In the case of farm animals, most cattle are tagged nowadays. Most large offices have their IT goods tagged as well and we all know that fashion stores have been tagging clothes for years, although maybe you did not realize what that button was that they were removing at the till.

Individuals are already tagging their dogs, cats and cars and it will not be long before these asset management techniques will be used extensively at home as well. Insurance companies may demand on it.

Owen Jones, the author of this article writes on quite a few topics, but is currently concerned with the RFID asset management. If you would like to know more, please go to our website at Active RFID Management.
