Study Notes

Early Calculating Devices

The abacus was the first calculating device with beads sliding on a wooden frame.
It is still used in many countries and is used for teaching basic arithmetic operations to children and blind students.
The abacus is thought to improve concentration and memory skills.
John Napier created Napier's bones in 1616, with numbers carved on bones or strips of wood.
Napier's bones were used for basic calculations, including finding square roots.
Blaise Pascal invented the first mechanical calculator, the Pascaline in 1641.
The Pascaline was a rectangular box with movable wheels for performing calculations.
Charles Babbage invented the difference engine in the 19th century, which was used to prepare mathematical tables.
Charles Babbage is considered the father of modern computers for his contributions to computing.
He also invented the first general-purpose computer, the analytical engine, which included the basic elements of a modern computer.

First-Generation Computers

First-generation computers used vacuum tubes and were very large and expensive.
They had small internal storage and relied on punched cards and paper tape for input.
The Mark I, designed in 1944, was a fully automatic calculator.
ENIAC was developed in 1946.
It was the first fully electronic computer using 18,000 vacuum tubes.
ENIAC occupied over 63 square meters and weighed over 27,000 kilograms.
ENIAC was designed to assist the army in launching bombs and missiles accurately.
EDVAC was proposed in 1944.
John von Neumann joined the design team and helped develop the concept of stored programs.
UNIVAC I was the first commercially available computer that could process numeric and textual data.
First-generation computers had limitations including slow speed, high power consumption, limited programmability, and high cost.
EDSAC was the first electronic computer using stored programs.

Second-Generation Computers

Second-generation computers used transistors.
They were smaller, faster, cheaper, and more efficient than first-generation computers.
They included components seen in modern computers, like printers and disk storage.
They used punched cards for input and introduced programming languages like COBOL and FORTRAN.

Third-Generation Computers

Third-generation computers used integrated circuits (ICs) or chips.
They were smaller and had enhanced storage capacities than second-generation computers.
They used operating systems to run multiple programs simultaneously.
They incorporated keyboards for input and monitors for output.
They were cheaper than second-generation computers.
Examples include the IBM 360 and 370 series.

Fourth-Generation Computers

Fourth-generation computers use microprocessors (VLSI chips) that contain all CPU components on a single chip.
They are smaller, more efficient, and have greater computing power and storage capacity compared to previous generations.
They use improved and cheaper storage devices.
They can be networked to share resources.
Examples include IBM PCs and Apple Macintosh.
Laptops, palmtops, and tablets are common now.
The drawback of fourth-generation computers is their lack of ability to think.

Desktop computers are the most common type of microcomputer, found in offices, homes, etc.
They are sometimes called personal computers (PCs).
Mainframes are large computers used in businesses like airlines and banks.
Supercomputers are the most powerful computers used for complex calculations in industries like weather forecasting.

Mainframes

Mainframes are large, powerful, and expensive multi-user computers.

Examples include IBM Z16 and NEC 610.

Supercomputers

Supercomputers are the biggest and most powerful computers.
They occupy whole rooms and can process trillions of instructions per second (TIPS).
Government organizations and large industries use them for tasks requiring complex calculations.
Examples include Frontier and Fugaku computers.

ICT Devices and Applications

ICT stands for Information and Communications Technology.
It covers communication devices and applications such as computers, mobile phones, tablets, printers, scanners, software programs, and projectors.

IT is a rapidly growing industry with applications in education, health, finance, entertainment, agriculture, business, and more.

Advantages of ICT

ICT has improved quality of life by enabling faster communication and remote work and study.
It saves office space for businesses.

Disadvantages of ICT

Disadvantages include network failures, reduced social interaction, and the risk of cyber attacks and hacking.

Communication Applications

ICT devices are used to access information, transfer data, and enable electronic communication like text messages, video calls, and broadcast media.
It is used to transfer files between devices.

Manufacturing Applications

Manufacturing industries employ robots and manage production lines using ICT.
ICT makes the manufacturing process efficient and effective, enabling mass production and distribution in a short time.
It reduces production costs by minimizing human labor.

Measurement Applications

Computers can accurately measure incredibly large or small amounts of data.
ICT is used to measure sports performance, monitor vital signs of patients, and measure environmental data like temperature, pressure, and humidity.
Navigation systems use ICT to help people locate places using online maps.

Business Applications

ICT is extensively used to manage businesses for e-commerce, communication, advertising, trading, customer care, and data handling.
Surveys and polls are used to collect opinions about products and services.

Data and Information

Data is a collection of facts, while information is the organized and interpreted data.
Raw data does not carry meaning, but when processed, it becomes meaningful information.
Computers cannot make decisions based on raw data, but information can help in forming decisions.
