IOS and Android

 

The main difference between the two OS is the Android is the most open source of the two. This gives the added benefits of more customisation option and easier development for games programmers. This is mostly because it is based on the Linux operating system. IOS is more restricted which is better for security but will also make it harder for games business to get their games on the app store which is the equivalent of the google play store.

Both operating systems stores have to go through a process to get their games on the stores. How apple is more protective about what is on their stores. This means it will have to follow the guidelines and terms of service. There is also a fee for uploading your game. For Apple this is a $99 a year charge buy on Android the is only a $25 charge per game. Each system has its benefits. For IOS this is the fact that users with IPhone are more likely to pay for app and in app purchases. For Android this is the fact that a larger amount of users has them, this means that your app will reach a larger audience.

In terms of development Android has the upper hand. This is because games can be made on almost every engine and can be exported as an APK which is the extension that Android uses for apps. As the user of Android are less restricted then IOS these APKs can be downloaded and ran even if they are not on the play store.

Different types of Ram

SDRAM: Synchronous Dynamic Random Access Memory

Started to be used in systems in 1996 Unlike older variants it timed its processes to the CPU clock speed. This makes the system more efficient as the CPU does not have to wait for the memory to catch up to receive the information ready for processing. This type of memory is only Single Data Rate which means the I/O, internal clock and bus clock are the same. This has the negative of this type of Ram only being able to read/write once per CPU cycle. This means it will have to wait for the next cycle to give new information.

DDR SDRAM

This stands for Double Data Rate SDRAM. This allows the transfer of data twice per clock cycle. This improves the rate at which tasks are performed as it does no limit the the rate the CPU and process the information. This doubles the speed at which data can be passed without changing the overall clock speed or speed of the Ram.

DDR2

This improves the bus signal from normal DDR. This increases the overall transfer speed so that information is transferred faster. As well as the voltage and power consumption has been reduced. This means less power will be wasted which is useful for machines like servers that are on all the time.

DDR3

The trend of reducing power consumptions continues with it being cut by 40% since the last iteration. The prefetch buffer width has also been doubled since last time which means that it can transfer the same amount of data in half the time of DDR2.

DDR4

The reliability of data transfers is heavily improved with the addition DBI (Data Bus Inversion) and CRC (Cyclic Redundancy Check). This will improve the stability of the memory. The overall transfer rate has also been drastically improved.

Arcade controls

DDR (dance dance revolution) was made in 1999 and changed the way that users play games with the use of new controls. DDR was a game where users had to follow arrows on a screen and match them by pressing on the correct arrow. This was done with the use sensors that tracked what button was being pressed on. DDR was a popular game in Japan until it became more competitive and came over to western audiences. The popular aspect of this game and controller scheme was that it relied on fast reaction and to some sense a form of physical finance to stay in time. This was not seen from games of the time. It saw the owner of the game Konami double their net income. This was mostly down to the simplicity of the controls and the fact that the game was safe for all audiences.

Later into the 2000s racing games started to be popular this was due to the use of racing wheels that gave the user a level of realism that was not seen before with the use of basic joystick controls. Wangan Midnight MAXIMUM TUNE 5 was one of the games that included this type of control. As well as this some system included a gear stick and foot pedals. This was an early simulation experience.

The invention of the joystick was in 1910 in England. However, it was only used in games from the early 70s with notable games like space race. This allowed the player to used two joysticks with one to make the character go left and right and a second to make the character go up and down. This was revolutionary at the time as before player where only restricted to one axis of movement. This allowed a more enjoyable experience with more user freedom. This was later improved in the 80s when Pac man came out. This combined the two joysticks into one creating an easier player experience. This could be done with the improvement of circuits so the game easily knew what direction the joystick was.
