Study Notes

Introduction to Information and Communication Technology (ICT)/Computer Systems

ICT is a diverse set of technological tools and resources for communication, creation, dissemination, storage, and information management
Includes computers, internet, broadcasting (radio/TV), and telephony
Computer is an electronic device that takes input, processes it, produces output, and stores results
A computer can also be defined as a machine accepting data from input, performing calculations, and transmitting data to an output device
Computer peripheral is an auxiliary device connected to the computer, not part of the core architecture (e.g., printer)
Peripherals extend computer functionality
Three types of peripherals: Input (mouse, keyboard), Output (monitor, printer), and Storage (hard drive, flash drive)

Concepts of ICT

ICT is a broad umbrella term encompassing communication devices, applications, encompassing computers, networks, hardware, software and their applications
ICT is used in various sectors, for example, in Agriculture, banking, manufacturing
ICT supports and disseminates information using resources like economic growth (e-commerce), and management (automating processes)

History of Computers/Generations

First Generation (1940-1956): Vacuum tubes, large in size, consumed lots of electricity, generated heat; used machine language, solved problems one at a time, input via punched cards/paper tape, output via printouts (e.g., UNIVAC, ENIAC)
Second Generation (1956-1963): Transistors, smaller, faster, cheaper, more energy-efficient that that of vacuum tubes; Input through punched cards and output through printouts; transitioned to symbolic languages (assembly languages); and early high-level languages like COBOL and FORTRAN
Third Generation (1964-1971): Integrated Circuits (ICs), reduced size; used keyboards and monitors, operating systems allowed multiple applications to run concurrently; improved speed, mass accessibility
Fourth Generation (1971-1984): Microprocessors, very complex circuitry (LSI, VLSI), led to the development of GUI, mouse, and handheld devices; marked the origin of mini-computers
Fifth Generation (1984-1990): VLSI (Very Large-Scale Integration) technology; microcomputers (PCs, IBM PCs, BBC Micro); designed for single-user, later transitioned to multi-user systems
Sixth Generation (1990-present): Incremental improvements, not fundamental changes; parallel computing, improved workstation technology (combination of RISC, pipelines, parallel processing); Wide Area Networks (WANs), faster networks, and high-bandwidth connections; use of graphics, and GUI, microcontrollers

Classification of Computers

By Purpose: General-purpose (handles a variety of tasks), Specific-purpose (performs a specific task)
By Data Handling/Functionality: Analog (continuous physical phenomena), Digital (discrete digits), Hybrid (combines both analog and digital)
By Size: Supercomputers (fastest, most powerful; e.g., weather forecasting), Mainframe computers (large, support many users), Minicomputers (midsized), Microcomputers (personal computers (PCs))

Components of a Computer System

Hardware: Processor, storage devices, input devices, output devices
Software: Application Software (e.g., spreadsheets, word processing), System Software (e.g., operating systems, utility programs, translators)
