Computer Science: Personal Computers

Personal Computers

Hello, everyone! I hope you're having a good day, just like I am. The purpose of me writing today is to spread a little of information that I've gotten about personal computers. First of all, allow me to define the term.

According to Wikipedia, a personal computer (PC) is a computer of general-purpose whose size, capabilities, and original sale price make it useful for individuals, and is intended to be operated directly by an end-user with no intervening computer time-sharing models that allowed larger, more expensive minicomputer and mainframe systems to be used by many people, usually at the same time.

Although "PC" is an initialism for "personal computer", it is sometimes used in a different sense, referring to a personal computer with an Intel x86-compatible processor. Some PCs are equipped with x86 or x64 processors but not designed to run Microsoft Windows. "PC" is used in contrast with "Mac", an Apple Macintosh computer. Since Apple's transition to Intel processors starting 2005, all Macintosh computers are now PC.

There are two types of personal computers, namely stationary and portable. Examples of stationary personal computers are workstation, desktop computers, gaming computers, nettop, etc. Meanwhile for portable, the examples are of those we often hear nowadays all around us - laptop, netbook, tablet, and so forth. In the pictures above, netbook can be seen on the left side and nettop on the right side.

Generally, a computer user uses application software to carry out a specific task. System software supports common services such as memory management, network connectivity and device drivers. Typical examples of software applications are word processors, spreadsheets, and media players. Multiple applications bundled together as a package are sometimes referred to as an application suite.

End-user development tailors systems to meet the user's specific needs. User-written software include spreadsheet templates, word processor macros, scientific simulations, graphics and animation scripts; even email filters are a kind of user software. Users create this software themselves and often overlook how important it is.

This concludes my post today. Feel free to send comments or criticisms whereby I can try to fix what's lacking in order to be able to publish a better post in the near future. Thank you for spending your time to read my post. Have a good day, everyone!
