Question

Answer the questions: 1. What does the term “computer” describe? 2. What are five components of computer system? 3. What is connectivity? 4. What’s the difference between hardware and software?

Answer 1

Ответ:

1. A computer is a programmable device for storing and processing data.

2. Five basic components of computer system are input unit, output unit, storage unit, CPU (central processing unit), ALU (arithmetic & logic Unit) and control unit.

3. Connectivity is the transfer of information between computer devices (hardware and software).

4. The difference is that the hardware is a set of electronic and mechanical devices located in the computer case (and not only) and necessary to run PC (and expand its functionality), and the software is a set of programs stored in the computer's memory.

Answer 2

1. The term "computer" generally refers to a device that is capable of processing information and executing tasks according to a set of instructions. It can perform various operations, such as calculations, data storage, and communication.

2. The five components of a computer system are:

   a. Central Processing Unit (CPU): It is the "brain" of the computer responsible for executing instructions and performing calculations.

   b. Memory: It is used to store data and instructions that are currently being processed by the CPU. It includes primary memory (RAM) for temporary storage and secondary memory (hard drives, SSDs) for long-term storage.

   c. Input Devices: These are devices through which users provide data or commands to the computer, such as keyboards, mice, touchscreens, scanners, etc.

   d. Output Devices: These devices display or present the processed information from the computer to the user, such as monitors, printers, speakers, etc.

   e. Motherboard: It is the main circuit board that connects and allows communication between various components of the computer, including the CPU, memory, storage devices, and other peripherals.

3. Connectivity refers to the ability of a device or system to establish connections and communicate with other devices or networks. It enables data transfer, sharing of resources, and communication between devices, either locally or over long distances. Connectivity can be achieved through various means, such as wired connections (Ethernet cables, USB), wireless connections (Wi-Fi, Bluetooth), or network technologies (Internet, LANs, WANs).

4. Hardware and software are two fundamental components of a computer system:

   Hardware refers to the physical components of a computer system that can be touched and seen. It includes devices such as the CPU, memory modules, hard drives, graphics cards, input/output devices, and the physical structure of the computer itself. Hardware provides the necessary infrastructure and resources for executing software and processing data.

   Software refers to the non-tangible programs, instructions, and data that are stored and executed by the hardware. It encompasses the operating system, applications, utilities, and other programs that enable users to perform specific tasks on a computer. Software provides the instructions and algorithms that the hardware follows to carry out different operations.
