Why computers are powerful? Flashcards
What are the various reason that makes a computer powerful?
remarkable speed, reliability, consistency, and accuracy
can store large amounts of data and information. it also allow users to communicate with other users or computers
computer
is anyone who communicates and interacts with a computer or makes use of the information it generates.
user
In the system unit, operations get done through electronic circuits. When data, instructions, and information drift along these circuits, they travel at incredibly fast speeds. Most computers bring out billions of operations in a single second. The world’s fastest computer can perform trillions of operations in one second.
speed
The electronic components in modern computers are dependable because they have a low failure rate. The high reliability of components enables the computer to produce consistent results.
Reliability and consistency
Computers process large amounts of data and generate error-free results, provided the data is inputted correctly and the instructions work properly. If data is inaccurate, the resulting output is also incorrect. A computing phrase known as garbage in, garbage out points out that the accuracy of a computer’s output depends on the accuracy of the input.
Accuracy
happens between two or more people sending and receiving messages from one another.
communication
The one sending the message is referred to as
sender
the one receiving the information is known as
reciever
can be classified based on size and computing power.
computers
have become smaller, yet more powerful, and relatively cheaper.

The general classifications of computers
Personal computers, workstation, minicomputers, mainframe, supercomputer
is a small, single-user computer based on a microprocessor. In addition to the microprocessor, a —- has a keyboard for entering data, a monitor for displaying information, and a storage device for saving data.
Personal computer
is a powerful, single-user computer. A —— is like a personal computer, but it has a more powerful microprocessor and a higher-quality monitor.
Workstation
is a multi-user computer capable of supporting from 10 to hundreds of users simultaneously.
Minicomputer
is a powerful multi-user computer capable of supporting hundreds or thousands of users simultaneously.
Mainframe
is an extremely fast computer that can perform millions of instructions per second.
Supercomputer
are computers designed to be placed on a desk, and are normally made up of a few different parts, including the computer case, central processing unit (CPU), monitor, keyboard, and mouse
Desktop computer
are hand-held computers with touch- sensitive screen for typing and navigation
Tablet computers
include fitness trackers and smartwatches that can be worn throughout the day.
Wearables
are the latest television sets that include applications present in computers. For example, videos can be streamed from the internet directly onto the TV. The TV can also be used as a computer monitor and gaming monitor.
Smart tv
are hand-held telephones which can do things that computers can do, including browsing and searching the internet and even playing console games.
smartphones
are battery-powered computer devices whose portability makes them possible to use almost anytime, anywhere.
