A desktop computer is a machine which is meant to be used at a single location. All the basic parts of desktop computers are considered hardware. The monitor, computer case, keyboard, mouse and power cord are considered the basic parts of a computer. The computer case is the plastic or metal box that contains the main components of the computer.
It comes in different shapes and sizes. It houses the motherboard, central processing unit and the power supply. The monitor is located outside the computer case and it works with a video card to display the text and images on the screen.
The power cord is the link between the power outlet and the power supply unit in the computer casing. If the power cord is not plugged in then the computer will not get on.
The next basic part is the keyboard which is a piece of hardware that resembles to a typewriter keyboard. It is one of the primary ways to enter data into the computer system.
The mouse is a peripheral that is also known as pointing device and helps one to point objects on the screen, click on them and move on. There are two types of mouse one is optical and other one is mechanical. A mechanical mouse uses a rolling ball to detect movement and is more difficult to clean. But it is less expensive and most of the desktop computers come with a mechanical mouse only.
Beyond these parts are the hardware items which are located inside the computer case and peripherals. These are optional pieces of hardware that makes the computer system more useful and enable one to accomplish additional tasks.
Inside the desktop computer is a central processing unit, which is often called the brain of the computer. Its job is to carry out the commands. Whenever one presses a key, click a mouse or starts an application, one is sending instructions to the CPU. This processor determines how fast a computer can execute the instructions. The speed of processor is determined in megahertz or gigahertz. The higher the hertz will be, the faster the computer will work and send instructions.
The CPU is generally of a two inch ceramic square with a silicon chip located inside. This chip is usually about the size of a thumbnail. The other part is RAM which is system's short term memory. The data is temporarily stored here until one saves his work to the hard disk.
The computer's work takes place in RAM. This is where programs run when one uses Word for creating a letter or Excel to produce a company spreadsheet. The RAM is also measured in megabytes or gigabytes. The other internal part is motherboard which is the computer's main circuit board that holds the CPU, memory, connectors for the hard drives and optical drives as well as various external ports and peripherals.
Besides these some of the other internal parts are network card, power supply unit, hard disk drive and expansion card, video card and sound card.
These days, the computer technology industry is rapidly growing and changing. Along with that growth and change of computer technology are the people who almost instantly adapt to the changes.
Computer technology has made our lives a lot easier and convenient. For instance our banking needs. Years ago, people had to manually file the important data of their customers; now they just use the computer to find these data. In just one click, they would instantly find the name of the customer, the birth date, the address, e-mail address, phone numbers and etcetera. As for the clients of these banks, they can also easily get a quick look at their account balances through logging in to the bank website; in addition to that a lot of people are able to apply for a loan with the use of the computer.
Because of the birth of computer technology, we now have credit cards or what others call plastic money, which are very useful especially when we do not have cash on hand or when you are ordering a certain product through the internet. It's amazing how computer technology has changed so much our way of living. Nowadays, purchasing products such as cellular phones, bags, household utensils, and clothes or even paying the bills can be effortlessly done at the comfort of your own home.
With the use of the computer a lot of students especially those with unfortunate disabilities or severe illnesses are able to enroll to different schools through home schooling. Students are even able to take their examination tests or check out their grades by the use of the computer.
As far I know computer technology has helped a lot of businesses to better serve the community. But the computers have not only helped us in the business industry; it also has an effect on our communication systems. Long before the computers were born, writing letters were the main source of communication, which would be such a hassle most especially to those people who lived in far away places; plus telephones were quite expensive so people would pretty much prefer writing to their loved ones. And for that reason, people 메리트카지노 who are far away from civilization would really have a hard time communicating with others. Now, we have e-mails, and live chat, or even voicemails. We now already have video calling in which we would be able to see the person that we are talking to. This would be really great for people who have loved ones that are away from home. Getting in touch with one another is now a piece of cake.
Computer technology has changed our lives for the better. Without it, we would still be living in the pre historic times.
