I got my TMA returned before Christmas and I was so happy, I got 99% just one mark away from 100%, I made a silly mistake on question 1 where I had to calculate my average score for the first 6 chapter exams, I did the calculations correctly but for some reason I put down the wrong answer. Nevertheless I am still happy with the score I recieved it is the highest grade I have ever had.
I am still enjoying TM257 and I was talking with my partner the other day and I said that these two modules I am doing I have not had any "boring" bits I have enjoyed all of it so far. I still find it challenging but I guess thats a good thing as it means it pushes me to do well and if I do not grasp the concept because of they way the material is written then I alway consult Google, and I do a little research of my own to try and fully understand the subject.
I will be going to the compulsary day school I think its about April this is where we can play with actual brand new Cisco equipment and set up scenarios I am looking forward to it but also a bit nervious as there is a test at the end. The other issue is that the closest day school to me is Wales which is about an 1 hour 40 minutes away.
I have not written on my blog for a while, mainly due to the reason that stage two of my studies is a lot more in-depth (as it should be). I have been enjoying both modules, I may talk more about each module later, but for now, I would like to say that I got the first TMA back today with a score of 70/100, it's not my best score I have ever had, but it's most certainly not my worst!
My tutor has given me some great feedback, it's mainly that I have not used all the course material as I should have with my report. To be fair I'm not a report writer, but I know that I need to do it as if I get a job in the IT sector as a network administrator then report writing may be a reality as I would have to write reports on proposals for implementing new technology to the existing network etc. I'm not shying away from report writing but I am not jumping up and down either!
I'm not a natural when it comes to writing HTML code, I don't have much experience and to think that I can understand what is going on the picture and what the element names mean and do is a bit step up for me.
As for TM257, I am progressing at a steady pace, I have already completed the first TMA, I have not submitted it yet just in case there is something I remember or I have to do as well before the cut off date of the 13th December. I have learned more about networking in the last couple of months than I have in my entire life!. It is a lot to take in and I am making good use of Packet Tracer as well as the hardware I purchased, I bought two Cisco 3560 switches and Cisco 2851 router.
Here is a picture of my little setup, they don't stay on all the time, mainly because they are noisy and secondly they eat electric! as the caption says, the comms cabinet was given to me by my boss, we had two of them both of which have been sitting in our warehouse for the best part of 8 years!
This is all I have to say right now, however, I am quietly confident that I have done well in TMA 01 for TM257. I completed the packet tracer activity and troubleshooting the network and got that working. and I have done all the other questions. the only question I'm a bit concerned by is question 2 where I have to draw a diagram showing an encapsulated packet being used to send a web page from a web server to a client. I have done the question but I'm not sure if it is correct. Time will tell!
I received my first TMA back for MU123 (Discovering mathematics), I am so pleased that I got 94%. I was quite confident that I did well, I re-read it and re-read it again before I submitted it and made any alterations with it. My tutor gave me some constructive criticism which I will take on board.
Well I need to continue on with the study material, obviously, MU123 gives you about 2 weeks to do one unit, so it has taken me a while to juggle my time with studying this module as well as TM129, I have noticed that TM129 isn't really as heavy as MU123 in terms of the amount of time I need to put aside to study, I can complete a whole unit in TM129 in a day straight.
I am doing TMA 01 for TM129 at the moment and I have had a bit of trouble with it, it seems to be more in depth than TMA 01 for MU123 was. I have only got question 4 and 5 to do. Question 4 wants me to write a short report on the use of robots in the logistics industry mainly warehouses. This has proved more difficult that I first thought. I will let you know how I get on when I get my results in.
I must say that I don't find robotics that interesting, and I'm not really sure why this block is included in TM129, I understand that the module is "technologies in practice" however, after this block there is nothing else to do with robotics in the entire course i.e in Stage two or stage three. so by the time I go on to the next stage which should be next October, I would of forgotten everything I have learnt.
I have nearly finished iCMA for MU123 as well, this needs to be finished and submitted by 5th December. The TMA 01 for TM129 needs to be submitted by 7th December and then TMA 02 for MU123 needs to be finished and submitted by 19th December (which I have not even started yet!)
I have received my TMA back and it has been marked, I am really pleased with myself I got a score of 38 out of 50 which works out to be 76%, This has given me a bit of a boost in terms of my abilities.
In TU100 I have learnt that there're 4 generations of computers, the first one being from around WW2 these are the computers which use thermionic valves, such as the Colossus which was used to break the codes by the germans.
This machine used paper tape for data input, for the output it would send it to an electric typewriter.
The public did not know about this machine until it went on to the public domain in the 1970's, it is now an attraction at Bletchley Park, Milton Keynes, the original Colossus was decommissioned at the end of the war and dismantled and destroyed, but a working replica was produced which stands in its place today.
Another example of the first generation computers was the ENIAC (Electronic Numerical Integrator and Computer) this was built by the University of Pennsylvania this also used thermionic valves the same as Colossus. This computer weighed 27 tonnes and occupied 63 square metres and was 26 metres long.
It was used to for lengthy calculations for the US Military. The ENIAC was not very user friendly like computers are today it used to take weeks and weeks to set up a program and errors could occur and then you would have to start again. You could not save your program state either and it was very unreliable, it was under repair more than it was working.
On a side note, Thermionic valves were very delicate and used to break a lot, they discovered that if you left the machine on then the valves would last longer.
The Second generation of computers were those that used transistors, these came out in the late 1950's. These computers where still very large and still very expensive for example one of the first computers that had this transistor technology was IBM's 608 at a price of $83,000 that was a huge outlay for most companies. Most of the computers of course as I mentioned above they were large but a lot smaller than the Colossus and the ENIAC, some of these transistor based computers were about the size of wardrobes.
These new transistors were a few millimetres in diameter so they were less than a thousandth of the volume of the thermionic valve. Transistors were much cheaper to manufacture than valves and of course they were more reliable as well. the switching speeds were also much faster than that of the valves.
The third generation of computers saw rise of the integrated circuit (IC) this was also known as 'chip' or 'silicon
chip' with these computers punchcards and tape were the thing of the past they were no longer used for input and output instead they had peripherals known as 'keyboards' for the input and for the output they had 'monitors' so for the out put of data they no longer needed paper printouts, also in this generation the Floppy disk was introduced, The IC was much faster in terms of processing speed than any of it's predecessors. Many minicomputers and mainframes moved onto this technology. These silicon chips were made from several components integrated onto a single chip. The IC computers were also able to talk to each other through telephone lines these were called terminals and could be distributed across the country and connected to a single shares computer.
The fourth generation of computers are basically the computers of today - the microprocessor (CPU) all computers and devices including Smart phones, tablets laptops, set top boxes, and even televisions have microprocessors, the microprocessor came out in the late 1970's, it has reduced running costs and manufacturers are able to make in large numbers. With the rise to the microprocessor, home computers were very much a reality, as these processors were cheaper to make and as I said before companies to make large amounts of them every day people started to have a personal PC in their home.
