Introduction to Personal Computers

What is a Personal Computer?

***** personal computer ***** a sm*****ll computational device that relies in a microprocessor ***** manage the coordination of system software, inputs, outputs, application software and increasingly, integration to the Internet. ***** computers have progressed from large, desktop systems to increasingly thin ***** light lap*****p computers which can connect to ***** Internet through WiFi connections through 802.11 3G support (Malykhina 45). Forrester Research, a consult*****ncy that specializes in tracking laptop purchasing trends, predicts that there will be a 30% incre*****se in ultralight laptop demand. The basic components of the personal computer have been augmented to support the increased mobility and security ***** users as the ***** h***** become pervasive (Mossberg 1).

***** Does a Person*****l Computer Do?

***** ***** computer runs software application programs that enable them to be used in a wide v*****riety ***** contexts. From writing, ***** analyzing data using spreadsheets, to designing graphics, playing games, communicating and collaborating over the Internet including writing websites ***** blogs, personal ***** have ***** the most commonly ***** device in many peoples' lives. What's made the personal computer such an important part of many peoples' ***** globally is the ability ***** *****se devices to provide support both for individual tasks that rely on application programs, or more distributed and networked tasks ***** are completed either ***** networks or over the *****. It ***** be used for *****, video production, music composition, graphic design or a literally thousands of other uses, all constrained only by the ***** applications available for ***** specific ***** computer model and operating system.

What Are the Six Primary Components of a Computer?

***** six primary components of the computer ***** the input, output, processor, secondary storage, memory ***** software. Input devices include keyboards, mice, all *****ms of scanners including optical character recognition (OCR) and in older PCs, support for floppy diskettes. The ********** ***** are required ***** sending data and instructions to ***** Central processing Unit (CPU) which is where the ***** ***** the system is located. Output devices include the monitor or screen, supp*****t for printing, and support for saving ***** output of ***** to other forms of electronic media.

What Are Some Examples ***** Input and Output Devices?

***** of input ***** include *****, mice, voice-response *****s for the handicapped, touch-screen systems and scanning devices for reading Optical Character Recognition (OCR) *****. Output ***** ***** often based on technologies that produce hard-copy output ***** ***** and plotting techniques, including inkjet and laser printing technologies. ***** devices can also be based on visualizati***** technologies ***** LED and plasma screens, in addition to the previous-generation Cathode Ray Tube (CRT) ***** as well. Output devices can also be entirely electronic, ***** is increasingly ********** the case with the ability to ***** Hypertext Markup Language (HTML) for use directly on the Internet.

***** is System Software?

This is the component of any personal ***** that is also considered the operating system. ***** ***** acts as the coordination point between the microprocessor
