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.
Fifth-Generation Computers
- The focus of fifth-generation computers is achieving the ability to think.
- They are still under development.
- Supercomputers have high storage capacities, high speeds, and the ability to conduct advanced operations.
- The CRAY CS300 series is an example of a supercomputer.
- AI is a branch of computer science that aims to create computers that can think and behave like humans.
- Fifth-generation computers are expected to overcome the limitations of previous generations.
Classification of Computers by Size
- Mobile computers are the smallest and portable.
- Examples include laptops, ultra-books, netbooks, tablets, e-book readers, smartphones, and PDAs.
- Laptops are portable versions of desktop PCs.
- Notebooks are smaller than laptops and typically do not have DVD drives.
- Ultrabooks are slimmer and lighter laptops that offer the same performance as standard laptops.
- Microcomputers are used by a single person at a time.
- Desktop computers are the most common type of microcomputer, found in offices, homes, etc.

- They can process billions of instructions per second (BIPS).
- 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.
- ICT is used in daily life for activities like applying for jobs, communicating, booking tickets, making complaints, accessing news, etc.
- 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.
