In conclusion, i have actually achieve half of my goal.I have studied for the Digital Electronics and all i need to do now is concentrate on the new chapters and wait for my results.

New topic for Digital Electronics.I started learning Decoder, Multiplexer and Demultiplexer this term.It is a more difficult subject and i will have to spend more time just by understanding.

common test over

Common test has just ended.For the past 1 week, i have been studying on my common test, especially digital electronics. I do the tutorial questions and read notes on it.i spend more time on this subject then the other subjects.

Common Test is right round the corner. I have been focusing on my Digital Electronics and spending more time as this is one of the harder subject. i have spent 3 hours per day just to revise on it.

Busy Holiday

Holiday is finally here but no time to slack. I have been following my schedule and studying hard for the upcoming tests, especially digital electronics. The topics is getting harder and i will definitely go for the holiday lesson this Thursday.

It is complicating but it is fun.I also manage to finish the circuit.I have also presented the powerpoint for creativity and innovation.

Recently I have the digital electronics lab test and it really look like a bomb

The development of the digital computer over the last 30 years has really been synonymous with developments in semi-conductor technology. From the invention of the transistor at Bell Telephone Labs in 1947, the rate of progress has been ever quickening. In 1968, Jack Kilby, then working at Texas Instruments, produced the first 'integrated circuit', which contained just a couple of transistors on a chip about 1 centimetre square. A few years later, the first 'microprocessor' chip appeared. This came about as a result of some lateral thinking on the part of the team at Intel who were producing calculator chips. It was realised that it would make more sense to produce a single device which could be programmed to do different jobs, rather than a number of dedicated devices.

Since then, ever more powerful devices have been produced with associated improvements in all manner of silicon support devices, from ROMs to RAM's and everything in between! This pace of development seems to show no sign of halting and the next step will probably be towards silicon systems, with all the back up store contained in non-volatile RAM. One particular development in this direction is the wafer- scale integration which Sinclair are known to be working on. Here, individual chips are left all together as a wafer, rather than being individually packaged. The main problem is that software accessing of these devices will need to be adaptive in order to avoid any defective locations within the interconnected chips. By this means, it is anticipated that a silicon 'disk' of up to 3 megabytes could be produced but without any of the usual hardware.

Computers

understand only two numbers, 0 and 1, and do all their arithmetic operations in this binary mode. Many electrical and electronic devices have two states: they are either off or on. A light switch is a familiar example, as are vacuum tubes and transistors. Because computers have been a major application for integrated circuits from their beginning, digital integrated circuits have become commonplace. It has thus become easy to design electronic systems that use digital language to control their functions and to communicate with other systems.
