Personal Computer System Components
Can you imagine a world without computers? Computers have changed everyday life in infinite ways that we would have never imagined 50 years ago. Long ago, computers were primarily used to compute numbers and to do word processing. As times have changed, computers have also evolved to help us with our everyday tasks. Nowadays we even use our computers for personal enjoyment by using them for games and finding information on the Internet. One way computers play a vital role in everyday life is a computer that helps manage a nuclear power plant. One computer might take the place of numerous people by checking readings and calculating information. Having a thorough knowledge of how a computer operates and how the components interact is very important in understanding how a computer works.
When using computer terms, it is very confusing trying to refer to different parts. Computers are basically broken down into two groups so help organize parts. Hardware is the term used to refer to items that you can physically touch and move with your hands (Dais interview). Software is the term used when referring to items you cannot touch like programs and applications.
The motherboard is the main piece of circuitry inside your PC (personal computer). Like the downtown of a big city, it’s where everything happens. The motherboard is important because the most important things inside your PC cling to it (Dais interview). In fact, for the most part, the computer tower is simply a housing for the motherboard. Although the motherboard contains a lot of items, it is essentially one unit and is referred to as such (Gookin 114). As an example, a mall has many stores, but everyone calls it the mall.
At the heart of every computer beats the microprocessor. The microprocessor acts like a tiny, fast calculator (Ting interview). The microprocessor itself deals with other elements in the computer. These elements provide either input or output. Input is information flowing into microprocessor and output is information that it generates or splits up (Gookin 116). The overall performance of a computer of your PC depends in large measure of its microprocessor. Clock speed is measured in megahertz (MHz), or millions of pulses (cycles) per minute (Waters 61). You might think of a processor clock as a kind of metronome; with each beat of the clock -each cycle- the processor can execute an instruction from the software (Dais interview).
Softwares are instructions, commands, or data that direct the operation of computer systems. Hardware is the physical aspect of computers, telecommunications, and other devices. Hardware such as electronic circuitry and other components of a computer use software or programs to make technology do things. Hardware is permanent and not flexible, while software or programming can easily be varied and modified. You can put an entirely new program in the hardware and make it create an entirely new experience for the user. People can change the modular configurations that most computers come with by adding new adapters or cards that extend the computer's capabilities.
Computers have changed our lives in many, many different ways. We do a lot of things from computers and our portable devices such as get music, watch videos, pay bills, order dinner, keep connected with friends on social media sites like Facebook or Twitter, take college classes online, and many other things that I could make a 5 page list of all the things it can help us do straight from home but that would bore you to death. Now that I have told you how computers have changed our lives and how they are used in daily life, let me tell you the importance of the people working in computers and IT. These people are very important because without them who would you go to for help with your computer, make sure your information is safe, get viruses off your computer and keep it safe for kids from being attacked? That’s right, you wouldn’t be able to do any of this.
Software - the programs or language that controls the functioning of the hardware. Table of contents - a section on a CD that lists the locations of files to help a computer locate data.
Building a computer can be a useful skill in today's world. It allows you to
The motherboard is the main circuit board of a microcomputer. The motherboard contains the connectors for attaching additional boards. Typically, the motherboard contains the CPU, BIOS, memory, mass storage interfaces, serial and parallel ports, expansion slots, and all the controllers required to control standard peripheral devices, such as the display screen, keyboard, and disk drive. Collectively, all these chips that reside on the motherboard are known as the motherboard's chipset. On most PCs, it is possible to add memory chips directly to the motherboard. You may also be able to upgrade to a faster CP by replacing the CPU chip. To add additional core features, you may need to replace the motherboard entirely. (Glossary)
Processor speeds are measured in megahertz (MHz) and now come in speeds of up to 1000 MHz (1 GHz), which is very fast. This is almost ten times faster than the speed of most home computers, which average from 133 MHz to 166 MHz. Intel and AMD have been in a race to break the 1 GHz speed barrier, and the number of megahertz in the newest processors is not as significant as it was in earlier processors. For example, the difference between a 133 MHz processor and a 166 MHz processor is
“Computers play a key role in almost every sphere of life” (Berry, Terrie). Without them, everything would be different. People all around the world own or used a computer. Whether you are a professional in technology or just an average person, computers are still very important in your everyday life. “No other technology has accessed the world like computers and the use of the Internet have” (Maddox, Amanda). Without computers, consumers would not be able to do half the things as quickly as we can. Advances in computer design have increased its use for different industries, especially in the medical field.
Today, computers influence all lifestyles, and all different types of businesses. They have become an essential part of everyday life, from chatting, to e-mail, to commerce, to gaming. Almost every person in the United States has had some use on the computer. Since the technology age began, computers have become a mainstay in American and world society as much as the telephone, the automobile, and the television.
It’s prime role is to process data with speed once it has received instruction. A microprocessor is generally advertised by the speed of the microprocessor in gigahertz. Some of the most popular chips are known as the Pentium or Intel-Core. When purchasing a computer, the microprocessor is one of the main essentials to review before selecting your computer. The faster the microprocessor, the faster your data will process, when navigating through the software.
In designing a computer system, architects consider five major elements that make up the system's hardware: the arithmetic/logic unit, control unit, memory, input, and output. The arithmetic/logic unit performs arithmetic and compares numerical values. The control unit directs the operation of the computer by taking the user instructions and transforming them into electrical signals that the computer's circuitry can understand. The combination of the arithmetic/logic unit and the control unit is called the central processing unit (CPU). The memory stores instructions and data.
Hardware is a ware which you can touch and you can see. They need a computer function. It a hardware can be related to input, output and storage. They also can be call as physical component, such external hard disk (HDD), internal hard disk, mouse and etc.
Computers are helpful because they offer a wide range of functions and services that are not available anywhere else. There are four main uses: word processing, internet/communications, digital video/audio composition, and desktop publishing. Although one can create a typed paper with a typewriter, the computer has more features
There is a need for more computers in everyday life, in homes, schools and on the job. The advancement of computer technology today in all facets of the world, and life are growing to the point that everyone will need a computer to carry out their everyday life. Computer technology today is at the threshold of making life easier for everyone in the world.
CPU Stands for "Central Processing Unit." The CPU is the primary component of a computer that processes instructions. It runs the operating system and applications, constantly receiving input from the user or active software
From classroom activities to space flight and everything in between, computers are a vital part of daily life. Everything we do and every aspect of our life is affected by modern technology, like the computers. Computers let us dissect any sort of data. Computers make us reflect, hence we develop. Because of computers and the Internet, we can talk with individuals from diverse nations, and even see them via webcams.
