There is an area of study that attracting me recently, besides programming (well…the reality is I attracted to many things). OK, the post ahead will discuss about the computer’s hardware beside a lot of post about programming, me and every area I interested in, yaay. I am about to make a specific categories about the computer’s hardware and software.
Computer nowadays has been known trough out the world, but some of them know computer just as form of a desktop computer or notebook computer. Where they were slightly misunderstood the main idea of computer.
Computer is electronic device, operating under the control of instructions stored in its own memory.
or according to wikipedia
Computer is a general purpose device that can be programmed to carry out a finite set of arithmetic or logical operations. Since a sequence of operations can be readily changed, the computer can solve more than one kind of problem.
So, Computer is not only about PC, but every electronic device who process the input to produce an output and capable of storing the file. a computer it self contains many electrics, electronics and mechanical components known as hardware. And this hardware things divided to :
- Input Device : allows you to enter data and instruction into the computer
- Output Device : Hardware component that conveys information to one or more people
- System Unit : Case that contains the electronic components of the computer that are used to process data
- Storage Device : Holds data, instructions, and information for future use
- Communication Device : Enables a computer to send and receive data, instructions, and information to and from one or more computers or mobile devices
Computer also grouped into several categories according to size and purposes.
- Personal Computer
Personal computer can perform all of its input, processing, output and storage activities by itself.
- Mobile Computers and mobile devices
Mobile Computer : Personal computer you can carry from place to place. Ex : notebook
Mobile device : Computing device small enough to hold in you hand. ex : Smart phone, PDA.
- Game consoles
Game console is a mobile computing device designed for single player or multiplayer video games.
A server controls access to the hardware, software and other resources on a network.
is a large, expensive, powerful computer that can handle hundreds or thousands of connected user simultaneously.
is the fastest, most powerfull computer
