| | Freezes all time! Please help.. | | My computer hasn't been working very well for the last few days.It all started just a few days ago. I just wanted to do a summer-cleaning in my chasis and opened it. Then I used vacuum to take out some dirt.After making some cleanings very carefully, I re-assembled the chasis and pressed power-on. Then.. nothing..
The fans didn't work, no any sound from the pc but only the power led on.After that, I just went to a computer service to learn what the wrong thing is. They said my motherboard is dead. They sold me a secondhand one for a high price. Then they said my power is also dead. (While their motherboard was working with my pc it suddenly went out and the situation was just like the beginning) and as a result they told me that my power supply is faulty and causes death of motherboards. So, they sold me a power supp and then everything was looking fine.When I got home I found out that my pc freezes alot. Especially whenever I run a game, or WHENEVER I click "Test Direct 3d" in dxdiag it freezes immediately. I tried making a clean install of windows xp but even that was so hard due to lock ups during the installation and even the copying process which takes place... | |
| | Generation of computers............... | | The term 'computer generation' is used in relation to the hardware of the computers.Each phase computer development is chractrerised by the type of switching circuits used in them.There are five generations of computers namely,first,second,third,fourth and fifth.Computers which are used vacuum tubes are considered as first generation computers.They were very large in size and their programming was very difficult.The operating speed of first generation computers was very slow.These computer's consuption of power was high.ENIC,EDVAC,EDSAC,AND UNIVAC-I were some computers belonging of the first generation.Second generation computers used transistor,instead of vaccum tubes.these were highly reliable and cheaper than vaccum tubes Development of magnetic cores for storage was done in this period.Also second generation computers used high level languages,such as COBOL,FORTRAN etc.Operating systems also developed in this period.IBM_1401 and UNIVAC_1108 are examples of second generation computers.The third generation computers used 'Integrated Circuits' known as chips.These computers were highly reliable,cheaper and faster than second generation computers.Third generation computers used... | |
| | can electronics completely change the components used at the past? | | electronics is a field where there is always an advancement time to time. at the first we used vacuum tubes to be the best electronic component. but as the years went on there came the transistors and the diodes to replace these vacuum tubes. advancement must always be there in all the fields. but is this advancement is solely in dependent,that is, is this advancement does take the idea of its design of the new component from the past components.

Computers take numerous physical forms. Early electronic computers were the size of a large room, consuming as much power as several hundred modern personal computers.[1] Today, computers can be made small enough to fit into a wrist watch and be powered from a watch battery. Society has come to recognize personal computers and their portable equivalent, the laptop computer, as icons of the information age; they are what most people think of as "a computer". However, the most common form of computer in use today is by far the embedded computer. Embedded computers are small, simple devices that are often used to control other devices—for example, they may be found in machines ranging from fighter aircraft to industrial robots, digital cameras, and even children's toys.A computer in a wristwatch.The ability to store and execute programs makes computers extremely versatile and distinguishes them from calculators.
