GROUP 1 PRESENTATION INTRODUCTION TO COMPUTING  Title: Overview of Computer Systems and Key Concepts  Subtitle: Understanding the Core Components and Concepts  Presented by : Llamado, Guevarra, Cabiling, Adiarte, Alcoser, Gigante  Date Presentation: November 25, 2024 Overview of Computer System and Key Concepts  Computer System - is a group of devices (hardware, software, and liveware) intended to manage, process, receive, and display data in an understandable way. Components of Computer System  Computer hardware - are a computer's tangible and intangible components.  Computer software - Also referred to as programs or apps. They are split into two classes: system software and application software.  Liveware - is the person who uses the computer. known as humanware or orgware as well.  COMPUTER HARDWARE  The actual, tangible components of computers that facilitate key operations including input, processing, output, secondary storage, and communication are referred to as hardware. HARDWARE CATEGORIES (Functional Parts)  A collection of interconnected devices that can input, output, process, and store data and information is called a computer system. A computer system's input, processing, storage, output, and communication devices are its five primary hardware components.  Hardware Components  Central Processing Unit (CPU): The CPU, usually referred to as the "brain" of the computer, is the main element in charge of calculations and commands.  Memory: The CPU uses memory, commonly referred to as "RAM," as a temporary storage space. It keeps information and commands that the CPU needs to access rapidly.  Input/Output Devices: Input devices allow users to enter data and instructions into the computer.  Hardware Components  Storage devices: Hard drives and solid-state drives are examples of storage devices that offer long-term data and file storage. Even when the power is off, they enable the computer to save data and recover it later.  Motherboard: The motherboard links and facilitates communication between the computer's parts.  Power Supply: The power supply unit delivers power to all computer components.  Hardware Components  Cooling systems: Computers need fans or liquid cooling systems to prevent overheating and hardware damage.  Network Interface Card (NIC): The NIC is a piece of hardware that links a computer to a network and enables communication with other networked devices.  Peripherals: A computer can link to extra devices called peripherals to expand its functionality. External hard disks, printers, and scanners are a few examples. Software Components  Operating systems: A computer's hardware and software resources are managed by an operating system (OS). It preserves storage and memory as well as the computer's interface with input/output devices. Software Components  Applications: Also referred to as "programs" or "software," applications are the specific tools users utilize to carry out activities. Word processors, online browsers, and video games are a few examples. Software Components  Drivers: Specialized software programs known as drivers provide the operating system access to hardware components. The computer can use input/output devices and other hardware reasonably because they link the operating system and the hardware. Memory  The processor performs all the fundamental computation of the computer system. Other components contribute to the computation by doing such things as storing data or moving data into and out of the processor. But the processor is where the fundamental action takes place.  A processor chip has relatively little memory. It has only enough memory to hold a few instructions of a program and the data they process. Complete programs and data sets are held in memory external to the processor. This memory is of two fundamental types: main memory, and secondary memory. Main Memory  is sometimes called main storage.  is sometimes called volatile because it loses its information when power is removed  closely connected to the processor.  stored data are quickly and easily changed.  holds the programs and data that the processor is actively working with.  needs constant electric power to keep its information. Secondary Memory  iswhere programs and data are kept on a long-term basis. Secondary memory is sometimes called secondary storage or mass storage. Secondary Memory  stored data are easily changed, but changes are slow compared to main memory.  used for long-term storage of programs and data.  does not need electric power to keep its information. Networks  A computernetwork consists of two or more computers connected so that they can exchange data and programs.  Local-Area Network  In a local-area network only a few dozen computers are connected together, usually all located within the same building. Wide-Area Networks  A wide-area network can connect thousands of computers together over great distances.  Wide-Area Networks  A wide-area network can connect thousands of computers together over great distances. The long distance connections are made by using optical fiber, telephone lines, microwave radio, and satellite communications.  Internet Protocols  Internet protocols are a set of rules that allow computers and other devices to communicate over the Internet. These protocols ensure that data is sent, received, and understood correctly between different systems.  Internet Protocols  TCP/IP(Transmission Control Protocol/ Internet Protocol): ensures that each computer that is connected to the Internet is having a specific serial number called the IP address.  SMTP(Simple Mail Transfer Protocol): is important for sending and distributing outgoing emails.  FTP (File Transfer Protocol): is used for transferring files from one system to the other.  HTTP(Hyper Text Transfer Protocol): is used to transfer hypertexts over the internet and it is defined by the www(world wide web) for information transfer. References  https://peda.net/kenya/ass/subjects2/co mputer-studies  https://learn.saylor.org/mod/book/tool/pri nt/index.php?id=67412  https://www.geeksforgeeks.org/types-of- internet-protocols/  https://www.javatpoint.com/what-is-a- computer-system THANK YOU
