HARDWARE AND SOFTWARE
1. What do you know about the hardware and software?·
Hardware or hardware is often referred to as an object of the present
computer can be viewed and in touch with our sense of touch. hardware is forming device of the computer, while software and other supporting components of a computer.Components - Basic Hardware Components:- Monitor- Keyboard- Mouse- CPU·
Understanding Software is a collection of electronic data is stored
and regulated by the computer, electronic data stored by the computer
it can be either programs or instructions that will run a
perintah.Software or computer software based on its distribution can be
divided into several types, namely paid software, free software or free (freeware, free software, shareware, adware)2. Why is the role of hardware is needed in the processing of information? Explain!Because the hardware can work on orders that have been specified therein, or also called by the term instruction set.Dengan of commands that can be understood by the hardware, the hardware can meelakukan various activities that have been specified by the command.Physically, the computer consists of several components, which is a component system.Sistem are working together to form a union, if one component does not work, will result in malfunction of computer processes well. Computer components are included in the category of hardware elements.Computers are divided into:· Input device (input units)· Process device (processing unit)· Output device (output units)· Backing Storage (storage unit)· Peripherals (additional units)
The basic components of the computer consists of input, process, output and storage. Input device consists of a keyboard and mouse, the process device is a microprocessor (ALU, Internal Comminication, Registers and Control section), Output devices consist of a monitor and printer.
3.Apa you know about Operating System Software?Computer operating systems are computer software or software that is tasked to perform the control and management of hardware and basic system operations, including run software applications such as data processing programs that can be used to facilitate human activity. Operating Systems in English is called Operating System, or usually in short with the OS.Operating system software on your computer is a first layer that is placed on computer memory, (computer memory in this case there are hard drive, rather than ram memory) when the computer starts up. While other software is run after running the Operating System Computer, and Systems Operations will perform the core public service for the software. Common core services such as access to the disk, memory management, task scheduling, and user interface. So that each software no longer need to perform the core duties of the public, because it can be served and performed by the operating system. Section of code that perform the core duties and the general was named by an Operating System kernel.Operating system serves as a liaison between the hardware layer and software layer. in addition, the computer Operating System is also doing all the important commands in the computer, and ensure that different applications can run smoothly functioning simultaneously without a hitch. Computer Operating System ensures other software applications can use the memory, perform input and output to other equipment, and have access to the file system. If multiple applications running simultaneously, then the Computer Operating Systems will arrange a proper schedule, so that as much as possible all the processes running on computers that have enough time to use the CPU and not mutually interfere with other devices.Examples of such computer operating system is Windows, Linux, MacOS, etc.
4. Why Software applications desperately need the operating system? Explain!Software application is a program that has a command processing activities necessary to execute user commands with a specific purpose. So if the lack of the operating system command given by the user to the software can not be processed, because everything comes from the operating system.
