Define ICT, its tools, components, hardware, software, and the functions of CPU and printer.

SECTION A 1. The term "ICT" stands for Information and Communication Technology. 2. ICT tools are digital devices, applications, and systems used to create, store, retrieve, transmit, and manipulate information. Examples include computers, the internet, and mobile phones. 3. One component or tool commonly associated with ICT is a computer. 4. A computer is an electronic device that manipulates information or data. It has the ability to store, retrieve, and process data. 5. Hardware refers to the physical components of a computer system that can be seen and touched. 6. Two examples of computer hardware are keyboard and monitor. 7. The work of the printer is to produce hard copies of electronic documents, images, or text onto paper. 8. Hardware are physical components of the computer. 9. Microsoft Word is an example of application software. 10. The work of the CPU (Central Processing Unit) is to execute instructions, perform calculations, and manage the overall operations of the computer. SECTION B QUESTION 11 a. An abacus is an ancient manual calculating tool consisting of beads or counters that slide on rods or in grooves. It was used in ancient times primarily for performing arithmetic calculations like addition, subtraction, multiplication, and division. b. Three early mechanical calculating devices and their inventors are: • Pascaline by Blaise Pascal • Stepped Reckoner by Gottfried Leibniz • Difference Engine by Charles Babbage c. Blaise Pascal's Pascaline was an arithmetic machine designed for addition and subtraction, using a series of gears. Charles Babbage's card system, used in his Analytical Engine, was a programmable system that used punched cards to input data and instructions, allowing for more complex and general-purpose calculations. d. The ENIAC was a second-generation of computers (true or false) False. The ENIAC was a first-generation computer. e. third generation of computers introduced microprocessors. (true or false) False. Microprocessors were introduced in the fourth generation of computers. The third generation introduced integrated circuits (ICs). SECTION B (Continued) a. Computer hardware refers to the physical, tangible components of a computer system that can be seen and touched. b. Two examples of computer hardware are mouse and hard drive. c. The two main components of the computer system are hardware and software. d. Computer software is a set of instructions, data, or programs used to operate computers and execute specific tasks. It is the non-physical part of a computer. e. Two examples of computer software are operating systems (e.g., Windows) and web browsers (e.g., Chrome). Send me the next one 📸
