COMPUTERS TODAY
Computers are necessary in today’s society. We live in a fast-moving world where almost everything must come to us instantly.
The digital age has affected all of our lives and today’s society is no longer able to function without computer technology.
Therefore, we can say computers are vital in today’s society as they make life much easier for everyone.
Definition and characteristics of modern computers
What is a computer?
A computer is an electronic device that accepts user input (data), processes it under special instructions (programs), to produce the desired meaningful output (information).
Alternatively, a computer can be defined as a programmable machine that receives input, stores and manipulates data, and provides output in a useful format.
MAIN CHARACTERISTICS OF MODERN COMPUTERS
Characteristics of Computer
Computer and its components
Computer: Computer itself a combination of different type of separate electronic device. i.e. Computer only will be a computer if it has an INPUT DEVICE, PROCESS UNIT, and OUTPUT DEVICE.
There is a variety of monitor available in the market such as CRT Monitor, LCD Monitor, Touch Screen Monitor, TFT Monitor etc.
Universal Serial Bus (USB) : This is used to connect the external device to the computer.
Computer Software
Software is a logical programme to handle/solve a complex problem.
Open Source Software : This type of software may be freely available and cannot be used in commercially. We can modify, and use it under the same license.
Computer Languages
Number System
Operating System
Linux (Ubuntu ) Desktop Elements
File Management in Linux (Ubuntu)
Computer Security
Denial of Services: The main aim of this attack is to bring down the targeted network and make it to deny the service for legitimate users.
Sniffing: Data can be seen and watched when it travels one computer to other computer. Generation of the Computer Charlse Babbase is known as the father of the computer he has invented first analytical computer in the year 1822
The characteristics of computers that have made them so powerful and universally useful are speed, accuracy, diligence, versatility and storage capacity. Let us discuss them briefly.
Computers work at an incredible speed. A powerful computer is capable of performing about 3-4 million simple instructions per second.
In addition to being fast, computers are also accurate. Errors that may occur can almost always be attributed to human error (inaccurate data, poorly designed system or faulty instructions/programs written by the programmer)
Unlike human beings, computers are highly consistent. They do not suffer from human traits of boredom and tiredness resulting in lack of concentration. Computers, therefore, are better than human beings in performing voluminous and repetitive jobs.
Computers are versatile machines and are capable of performing any task as long as it can be broken down into a series of logical steps. The presence of computers can be seen in almost every sphere – Railway/Air reservation, Banks, Hotels, Weather forecasting and many more.
Today’s computers can store large volumes of data. A piece of information once recorded (or stored) in the computer, can never be forgotten and can be retrieved almost instantaneously.
WHY DO WE STUDY COMPUTER STUDIES?
computers to generate reports, type essays and research homework
assignments.
students during higher education courses and their careers. Students as young as 12 learn how to create Electronic Spreadsheets, Power Point presentations, Databases and Website Design.
low-income areas have access to the world at large.
almost impossible to predict what will happen in the future.
careers. Computer studies provides a foundation that serves as a competitive advantage in a career, in whatever field one chooses. Examples of such jobs include: Typists, Computer operators, Computer technicians, System analysts, Computer programmers, Software engineers, Computer engineers, Database administrators,
website masters, Graphic designers, IT Teachers, etc.
