HL01- computer system corrections
Microcomputer: This type of computer is going to use micro- processor for the central processing unit instead of using the vacuum tubes which were quite popular before the micro-processors, however these microcomputers are small enough to fit on a normal sized desk, in today’s computer these are known as the microcomputers, however the computer use to be quite slow and very expensive between 1940’s to 1960’s as it needed a large amount power to keep it on compared to the ones that are a lot smaller and easier to use on a daily basis. Cost of microcomputer

The cost of the microcomputer can range from starting at low end £200- £700 depending on the hardware or software and also how much can you afford when purchasing one. High end cost from £800 -£ 18, 00

Speed of microcomputer
Microcomputer has a CPU, RAM, Sound Card, Modem, and Video Card and is slower than other high performing computers such as a server or a mainframe, companies that are well known brands such as Sony, compact and other have given the processor speed of 1.2 or 1.4 GHZ, however smart phones run on even higher GHZ making temporarily out of date until 2009 when there were all upgraded to windows 7 which made them better again. Minicomputer: This is a type of computer that was made by transistors and Ram, however this particular computer fall under the category in between the size of a large mainframe or microcomputer. The first minicomputer had just only had a maximum of just 12 bit processor which is nothing compared to today’s computers which are way better in terms of hardware and software which are now available for everyone buy. Cost of minicomputer

A standard minicomputer can cost from £300- £500 depending on the brand and quality of the product. Speed of minicomputer
Most minicomputers are usually 200- 500 kilo bytes per second when processing a piece of data. Mainframe computer: These are computers are powerful computers that can handle multi tasking operations which are made out to be very fast yet it has a high performance than all the other computer out there, however this can help assist smaller server that businesses may use in various sectors within the investment or banking sectors. This particular computer is a little bit slower than a super computer meaning that the mainframe is less expensive than the super computer, but still for a normal person it still far too expensive to even think about buying. Speed of the Mainframe computer

The speed of the mainframe computer is at 5.5 GHZ which is incredibly fast.
Super computer: These are the fastest and the most expensive in the world of computers, however they would cost around 100 million pounds to build as only a few major cooperation can afford to buy them, however these are the types of people who may use these computer and they are; university professor who may use it for research projects, investment management, scientific research and drug companies. Cost of supercomputer

The whole computer system is going cost around 2 to 5 thousand pounds. Speed of supercomputer
This particular computer performance speed is around 5.5 petaflops when processing data which is extremely fast as this is the only computer which has it. Computer modelling: Process of creating an object l to simulate the behaviour and response of a wide range of systems and prototypes. This particular technology is used in the physical sciences known as medicine, and architecture as an aide to the design process. Mobile computers: Mobile computing are portable technologies that makes Internet access on the go easy accessible yet possible, however this technology has been incorporated in to our day to day life. Notebook computers to personal digital assistants (PDAs) like the Blackberry and iPhone, to standard cell phones; mobile computing has become a way of life. There are two types of wireless access services when away from the home or office, most commonly...
