Computer a powerful tool

Midrange servers are bigger and more powerful than workstation computers. The quickest and most powerful type of computer is called a supercomputer. Another extremely efficient computer is the mainframe, which can simultaneously manage thousands of linked users.

Why Is a Computer a Powerful Tool? For example, the first computer processor was the Intel , which was only a kHz processor capable of processing approximately 92, instructions per second. Today's processors are multi-core GHz processors capable of processing over billion instructions per second. Although today's computers can execute billions of instructions every second, the processor is usually waiting for those instructions from the slower types of memory in the computer.

Because RAM and the hard drive are slower than the CPU, computer processors and motherboards use cache to transfer data between the processor, memory, and other components.

The cache is the fastest type of memory, and a computer with more L2 cache or L3 cache can store more instructions and send them to the processor more efficiently. A computer with more memory RAM is capable of storing more programs that are currently running in memory. If your computer runs out of memory, the computer must swap unused data stored in memory to the primary storage device until it is needed again. By adding this extra step, and because hard drives and SSDs are the slowest types of memory , your computer can become much slower without enough memory.

For older computers, the bus speed of the motherboard increases the speed at which data is being transferred between all the hardware components. Computers are powerful tools because they can process information with incredible speed, accuracy and dependability.

They can efficiently perform input, process, output and storage operations, and they can store massive amounts of data.

Computers are designed to perform some task well, not to survive and replicate. Computers have changed the world in many ways. They allow huge amounts of information to be stored in a small space. They also allow a person to calculate mathematical problems with ease. Finally, computers allow people to communicate with one another through internet sites such as Facebook, My Space, and Twitter. The computer will be much faster and more powerful when it is capable of executing more instructions every second.
