You are asking what the processing speed is and the answer varies for individual madels. The speed is measured in parts of a second (rather than by the second) and many newer computers are now built with two processors that work together to further increase the processing speed and capacity.
they speed it up
Computers have changed considerably in size and speed in the last 20 years. This has made it possible for computers that would once fill a room to fit in your hand.
How Are Computers Used Today?
High speed computers,RFID chips,xenon bulbs,maintenance free batteries
Computers in the 1950s were much slower compared to modern computers. They had processing speeds measured in kilohertz (thousands of cycles per second) or even less, whereas today's computers commonly operate in gigahertz (billions of cycles per second). The average processing power was limited by the technology of the time, with rudimentary transistor-based machines that were much less powerful than today's silicon-based processors.
The invention of the microchip in 1949 - dramatically reduced the physical size of computers.
Speed, Reliability, Storage Capacity and ProductivityComputers of all sizes have common characteristics -- speed, reliability, storage capacity, and productivity. Computers are the foundation of business, travel, and leisure life today. Computers provide the processing speed required by all facets of society. The quick service we expect at the bank, at the grocery store, on the stock exchange, and on the Internet are dependent on the speed of computers. Can you imagine our world without computers?Computers are extremely reliable as well. Most errors are caused by humans, not computers. Computers are capable of storing enormous amounts of data that must be located and retrieved very quickly. The capability to store and retrieve volumes of data is at the core of the Information Age.
The speed of a modem is measured in bits per second (bps), typically expressed as kilobits per second (Kbps) or megabits per second (Mbps). This metric represents how quickly data can be transmitted and received over the internet connection provided by the modem.
Early Computers were large in size while today computers are compacted .Early Computers were Vaccum tube and transistor based while today computers are ICs based.Early Computers were slow and today computers are fast.Early Computers were used punch card for storage while today computers used Secondry storage ( Hard Disk) for storage.Early Computers were not user friendly todays computers are user friendly
