Introduction
In this high-technology generation, information technology (IT) had become very important for every human being in this world. As information technology and information systems is very important to business too, so we have to learn IT. But, to become IT genius, we have to know how to access IT with the help of computer. After this lecture, I learn that computer is not that simple as I thought. I also learn different types of computer’s component which very important to access computer.
This lecture also gives information about what is input., what are the input devices, and what is the importance of input devices. After this lecture about computer hardware, I feel that I have neglected the most important element about understanding the computer hardware and how an input devices functions.
What Is A Computer?
A computer is an electronic device, operating under the control of instructions kept in its own memory. The computer can accept and process data according, then it produce and save the results for future use (Gary B. Shellly 2012). In short, computer is devices that use to process information. In the help of computer, data or raw fact (input) can be transform into useful information (output).
A computer contains hardware and software. These two components is very important to functioning a computer. Basically, hardware refers to the electronic and mechanical components of computer. Software which also refers as program uses to operate computer. Let’s put our focus on the computer hardware.
Hardware
Like what I say just now, hardware is the electronic and mechanical components of computer. Without the hardware, computer cannot function well. Some example of these components is input device, output devices, storage device, communication devices and a system unit (Gary B. Shellly 2012). Hardware is important for processing data in computer.
What Is Input?
Input is any data and instructions entered into the memory of a computer (Gary B. Shellly 2012).
Input Devices
An input device is hardware component that allows you to enter data and instructions into a computer (Gary B. Shellly 2012). Input device is a peripheral device. Peripheral devices mean that the components are outside the main computer system unit (Kenneth C. Laudon 2009). Some examples of input device are keyboard, computer mouse, scanner etc.
Keyboard
Keyboard is an input device. It contains keys users press to enter data and instruction into the computer (Gary B.
1. A device is a computer if it has an input device, central processing unit (CPU), internal memory, storage, and an output device.
Computer hardware engineers research, develop, and test computer systems and components such as processors, circuit boards, memory devices, and many more (Bureau of Labor Statistics). They design new computer hardware, create blueprints of computer equipment to be built. Test the completed models of the computer hardware that they design. Update existing equipment so that it will work will new software. Oversee the manufacturing process for the computer hardware. Maintain knowledge of computer engineering trends and new technology(Bureau of Labor Statistics).
Software - the programs or language that controls the functioning of the hardware. Table of contents - a section on a CD that lists the locations of files to help a computer locate data.
Softwares are instructions, commands, or data that direct the operation of computer systems. Hardware is the physical aspect of computers, telecommunications, and other devices. Hardware such as electronic circuitry and other components of a computer use software or programs to make technology do things. Hardware is permanent and not flexible, while software or programming can easily be varied and modified. You can put an entirely new program in the hardware and make it create an entirely new experience for the user. People can change the modular configurations that most computers come with by adding new adapters or cards that extend the computer's capabilities.
Hardware is the term used to refer to items that you can physically touch and move with your hands (Dais interview). Software is the term used when referring to items you cannot touch, like programs and applications. The motherboard is the main piece of circuitry inside your PC (personal computer). Like the downtown of a big city, it’s where everything happens. The motherboard is important because the most important things inside your PC cling to it (Dais interview).
Hardware and software combined with several other devices work together to makes up a computer system. One part has little value without the other. The components need each other to fulfill their potential. The way the components interact allows people to use the computer to complete many different tasks (Ambrose, 2005, p. 58). The purpose of this assessment is to recognize computer system hardware components including devices that perform the functions of input, processing, data storage, and output. The document will briefly describe each of these functions and give examples of the device that perform them. Furthermore, it will mention and describe the different classes of computers as well as briefly describe two classes of software with their examples.
Pointing device is an input devices that is used to allow user to input data to a computer. It is connected to the computers or laptops using a USB, PS/2, serial, or Bluetooth connection (Tyler, 2008). It functions to point somewhere on the monitor, click and drag item in the computer. It plays an importance role enables user interact with the computer for many purpose such as surfing the web, editing document, editing images, computer games (Kirschner, 2010) and many others. It is defined as a piece of equipment used for moving a cursor on a computer screen (Mac-Millan Dictionary). There are many types of pointing devices nowadays such as mouse, trackball, pointing stick, joystick, touch pad, touch screen, light pen and digitizer tablet.
A processor is a small chip that exists in computers and most, if not all computer devices (TechTerms, 2012). It can also be known as the Central Processing Unit or CPU. Its basic job is handling all the basic system instructions, such as processing the signals from the mouse, keyboard input and any other peripherals, while/and run...
Input devices are very important for computer system. Without input devices there have no any data and information can enter to the computer, the computer will become useless. There can input many types of information to the computer, such as videos, images, audios and the others by using difference types of input devices. Input devices transform the user's actions and data such as graphics, sound and pictures into the digital data that can be read by computer. The two most common input devices that are operated directly were the mouse and keyboard. A keystroke contains keys for numbers and letters for their specialized task, such as PgUp, Ctrl, and Shift. Sometimes user need to press more than one key for some functions. For example, as a user you need to get a capital letter P then you need to press the shift key and P key at the same time, like Shift+P it function also same like Caps Lock. If you want to copy some words you can press Ctrl+C. Next input device is the mouse. The mouse was developed as a pointing device when start to use graphical user interface (GUI). This input device was important for user to interact with computer by manipulate on monitor screen objects such as folders and files. It follows the user fingers motions to
A computer is a combination of several parts. These parts are Random Access Memory (RAM), a Central Processing
A computer is defined as “A computer is an electronic device that manipulates information, or data. It has the ability to store, retrieve, and process data” (Computer Basics: What is a computer?, n.d.). Similar to a typewriter, it’s able to create documents; however, the difference between a typewriter and a computer is that a computer has more functions. A computer allows one to not only create documents, but “play games, and browse the Web. You can also use it to edit or create spreadsheets, presentations, and even videos” (Computer Basics: What is a computer?, n.d.). Most people only think of a desktop and a laptop as a computer; nevertheless, computers have different forms. Tablets, game consoles, smartphones, and more are all computers. The first ever computer happen in
I do not know much what an input device is even I have been using computer for many years. I thought that an input device is just a component inside the computer. I also did not know the role of input device play. I am among those people who do not care much about the component inside the computer. Now as I reflect, seems like I have ignored the importance of an input device.
You usually say that the computer has 2 types of components. The hardware and software. The big difference between these 2 are that, you can touch and react with
An input device is any device that is connected to a computer and transfers information to react or appear on the monitor screen. Code is translated from the device to the machine. For example, a keyboard connected to a computer through a USB cord will tell the computer what letters or characters should appear on the screen. Some example of input and output devices on a computer are printers, mouse, camera, external drives, internet, microphone, and audio speakers. Storage is where information and documents are stored (computer technology, n.d.). The C drive is the primary internal storage on a computer, while a D drive is the secondary. There are also external drives and clouds used for storage. A television is also a device with inputs and
Do you see or use computer every day? Do you know what are considered computer? Living in the modern age, almost everyone has his own computer beside them such as desktop computer, laptop, cellphone and other gadgets. Because of its uses especially when it is connected to the Internet, people can’t live without it and they believe that they must have their own computer. In the article “Introductions to Computer” by Singh (2009), he defined computer as an electronic device that is controlled by the user. Using the input device, the user give the computer task to do which it will perform the set of instructions to satisfy the user’s wanted output. For example in searching informations, using the keyboard, the user will type what he wanted to
