What are the disadvantages of a computer?

One of them is that the power consumption required to read and decode instructions and to read and write registers is very high compared to the power used in the actual useful work of addition or multiplication or bitwise operations . Even with low-power embedded applications, silicon around the ALU consumes the most power.

Another disadvantage is the dedicated application's complexity and performance degradation. One reason is that the GPU bloomed in the late 1990s and early 2000s. Our general people are seeking to make the graphics in the game more beautiful, but the CPU can not provide the pixel we want. As a result, the industry is developing an increasingly powerful dedicated ASIC built to process floating-point numbers and provide the best graphics.

In contrast, I purchased Intel Core i 7 860 and Nvidia gtx 460 in 2012. It is said that the CPU uses about 80 W and the graphics card can be up to 200 W. The CPU tracks 8 threads simultaneously, and can process 4 of them simultaneously. This is a very complex circuit that attempts to minimize the computational delay using multilayer caches and instruction rescheduling, and multiple simultaneous internal pipelines to accomplish this. However, in terms of raw electricity, only 100 GFLOPS can be executed.

In contrast, the circuit configuration of the GTX 460 is not that complicated, but the number of concurrent processors is on the rise. It focuses on high throughput rather than low latency calculations. It can do about 1 TFLOP. This is 10 times the CPU, but power consumption is more than 2 times stronger.

In general, the more computer you use, the more power you consume than dedicated hardware. In other words, it is much cheaper to complete a complicated general-purpose computer and it is necessary to develop dedicated software to execute them instead of creating dedicated hardware (the speed really like a high-performance switch Unless necessary). Over time, the complexity of the graphics software has increased, so the GPU has approached a more general purpose CPU.

Disadvantages The main disadvantage of 4th generation computers is that the advanced technology required by microprocessor chip makers is the 5th generation computers (under development). Thinking Ability All these follow the user's instructions. Computer equipment with artificial intelligence is still under development, but some of these technologies are beginning to emerge and are used for things like speech recognition.

This includes the strengths and weaknesses of communication and information technology. While the advantages outlined are disadvantageous, today's computing technology requires communication via a computer. Anyone keeping up with the times will be left behind. Globalization means reaching out to people all over the world. If someone works in Canada, their families are in different countries, and they can connect with each other in a matter of seconds. You can also purchase online. You can purchase items from websites of other countries to transfer funds to accounts around the world.

By using a computer, the computer generation has reached different heights, and computers have advantages and disadvantages, making it easier to use tasks that previously were considered difficult. Briefly focus on each topic. From school to hospital business organization, computers are everywhere and I can not imagine that we will not use computers in our daily lives. The influence of PC on human beings is very large, and you can buy and sell products using computers. E-Learning searches almost everything online, plays video, uses it for commercial advertisement To do. And it can be found at your fingertips using a computer with internet. For its worldwide use and acceptance, students must use
