Computers are devices designed to facilitate human work. Computers are designed to run applications and provide a variety of job solutions. In fact, today the computer becomes an essential daily need.
PC is a term synonymous with personal computers such as desktop computers. Knowing the meaning of a computer can help identify the function of this device. Understanding the computer is related to how it works, its history, to its components.
Computer Components
A computer or PC is an electronic device that consists of several components. The components of a PC are Hardware and Software. The following is an explanation of the PC components:
Hardware (Hardware)
Hardware is all types of components on a computer or laptop whose physical parts can be seen with the naked eye and can be felt directly. So it can be said that hardware is physical computer equipment that is useful for processing input, processing, and output.
Hardware Type
– Input Device (Input or input device). This type of hardware is useful for entering information and data in the form of video, text, images, audio, and others into a computer. Here are some examples of such hardware, namely Mouse, Keyboard, Scanner
– Process Device (Device process). This type of hardware can be useful in processing data as well as running processes that exist on a computer system. Examples of these process devices are CPU, RAM, VGA, and many more.
– Output Device (Output or output device). This type of hardware is useful in displaying information and printing the results of data input that the user does. The data or information comes from hardware input that has passed the hardware process. For example, such as monitors, projectors, to printers.
– Storage Device (Device for storing). The next type of hardware is a storage device or better known as a storage device. Storage device is one type of hardware that functions to store computer data. Examples such as hard disks, flash disks, and optical disks.
– Peripherals (Enhancements). Additional tools are useful in helping the computer execute user commands. These devices are generally referred to as peripherals which are useful in connecting computer devices to the internet network. One example is a modem. Modem here can be used as a communication tool to convert digital signals into analog signals or analog signals into digital signals.<\/p>\n\n\n\n
Software (Software)
Software is digitally programmed, stored and formatted data, which has a specific function. Software or software does not have a physical form, but this software is a program that is useful for executing commands or instructions on a computer.
Software Type
– Operating system. The operating system or operating system (OS) is software or software that functions to control all the components contained in a computer machine. An example of an operating system is Windows, as a commonly used operating system.
– Application Software. Application software is a program written in a particular programming language to be applied to a particular field. Examples of application programs that are often used on computers are Microsoft Office to Adobe Photoshop.
– Helper Software. Assistive software is a program to assist the operating system. An example of this type of software is security software, such as AVAST Antivirus, Kaspersky, to Smadav. Its function is to protect computers from various kinds of attacks by destructive programs such as malware, spyware, adware, trojans and so on.
– Destructive Software or Programs. This malicious software or program may be better known as malware. Malware is a computer program that was created with the main intent and purpose of finding software weaknesses. Generally Malware is created to break into or damage a software or operating system. Examples are viruses, programs that have the ability to reproduce, manipulate data, infect, and change and destroy other programs.<\/p>\n\n\n\n
