LCD/Flat panel monitors- LCD is Short for liquid crystal display. LCD technology can be found in computer monitors. LCD displayer is the monitor; the main purpose of a monitor in a computer system is to show text and graphics, which are generated by the computer. The LCD monitor is connected by a cable. One side of the cable is plugged into the back of the monitor and the other side of the cable is plugged into the hard drive cable port. Computer case- A computer case is also known as a computer chassis, system unit, base unit or simply just a case. Sometimes they are referred to as a CPU or hard drive. The cases are mainly made by steel solid cover. Inside the Computer case there is the hard drive and inside the hard drive there are other components such as the motherboard, USB ports, power supply, Central Processing Unit (CPU) and Random Access Memory (RAM) Hard Drive- A hard drive is the scale of a paper-back book however heavier .The sides of the hard drive have been pre drilled, threaded holes for easy mounting in the 3.5 inch drive bay in the computer case. The back of the hard drive contains a port for a cable that connects to the motherboard. The Hard Drive has many components inside it such as the motherboard, USB ports, power supply, Central Processing Unit (CPU) and Random Access Memory (RAM) Power supply unit (computer)- If there is any component that is completely important to a computer, it is the power supply, without it, a computer is just a box full of metal and plastic junk. The power supply converts the alternating current (AC) line from your home to the direct current (DC) which is needed by the personal computer and then pass the current to each component for it to perform its task. Motherboard- I... ... middle of paper ... ... will not be able to function. Make sure all the cables are plugged in and that the Liquid Crystal display (LCD) Monitor, the keyboard and the mouse is plugged in as well. 2. When the computer is starting up, the monitor will have a blank and the computer will be loading and setting up. After it is set upped, it will show that everything in the computer is functioning well. 3. After that is done I will log on to my user, by using my keyboard and pressing ALT, Ctrl and Delete. After that I will type in my username and password. 4. When the computer is ready for usage I will use my mouse to go on the Start icon and left click on it. 5. When on the start menu there will be a list of various applications, but the only application I will need to use is Microsoft Word 2010. I will drag my mouse on to that icon and left click on it once and wait for it to load up. 6.
Power down the computer. If the power supply has an on/off switch, turn it off as well.
Hold down the Windows Key and Press the “R” key on the keyboard. This will prompt the RUN window, type “gpedit.msc” in the text field and Click
article # 1 it gives you tips on what to do if your computer is not turning on. I learned that sometimes the USP and others are not plugged in the right way and sometimes people can trip over to make them unplug a little. My mom has a computer and her computer never turns on so she checks if her cords are plugged in properly and it turns on.
1. A device is a computer if it has an input device, central processing unit (CPU), internal memory, storage, and an output device.
...g, the price of a power supply could be $175-$350. Items such as thermal paste or extra fans or water cooling parts to prevent overheating are very smart investments. These items listed are just a part of the main factors to look at when considering building a computer from scratch, no matter what its use will be for. You still will have to buy a monitor, mouse, keyboard, webcam, microphone, and speakers if not already obtained. I hope this guide will serve you well in your journey to your dream computer. Just watch prices, view ratings, and use common sense when shopping. If you don’t feel confident in building it yourself, try and find a friend do so, or try to hire a computer specialist to build it for cheap. You would rather have it built by someone who knows what they’re doing and have it run perfectly, than getting confused and accidentally mismatching pieces.
3. Hit “Ctrl ]” to exit. IMPORTANT – Do NOT exit HyperTerminal until you have logged out of BOTH the VOICEMAIL and PBX Command System (“logo” is the PBX logout command). Basic commands. LOGI =
Well, Before anything else, here is a few names of components that need to be known to not be completely lost. The CPU(Central Processing Unit) (It processes everything from basic instructions to complex functions.) (Techterms.com). The Hard drive (the location of all the computer’s folders, files, and information, saved magnetically so even if turned off it’ll all stay saved). The RAM (Random Access Memory) (The more RAM your computer has, the more data can be loaded from the hard drive into the RAM, which can effectively speed up your computer.)(Techterms.com), The OS (Operating System) (just what it sounds like, this is the system that works the computer, as in Windows, Linux, and Apple OS.) The Graphics card (helps the CPU by processing the graphics portion of what the CPU has to process). The Disk Drive( this is the CD,DVD, or Blu-Ray driver that is installed to use CD’s DVD’s and or Blu-Ray disks.) The last major term to know is the Motherboard ...
These devices are attached to the motherboard through different connections. The output devices like monitors and printers can be used by a file server to show different files or print hard copies of files. These devices take the data from the computer and put it into a format that users can read and understand. I would like to take a moment here and go over the different kinds of monitors that a person can use as an output device. The first is the regular CRT monitors are heavy and use a lot of electric power to display objects, but are preferred by graphical artist for the color rendition. Then there are the flat panel monitors, which can use liquid Crystal Display (LCD) or a plasma display. These displays use electronically at each pixel to control the color. The input devices like a keyboards and a mouse. These inputs take the movements from the users and turn it into data that the computer can understand. (Beach,
Some systems use a conventional computer monitor to display the visual world. This sometimes called Desktop VR or a Window on a World (WoW). This concept traces its lineage back through the entire history of computer graphics. In 1965, Ivan Sutherland laid out a research program for computer graphics in a paper called "The Ultimate Display" that has driven the field for the past nearly thirty years.
Computer icons within a GUI are supposed to resemble some real object. The success of an icon on communicating the right meaning to the user depends on the accuracy of the representation and, of course, the user's ability to recognize the relationship. Notice that a computer system will have all kinds of signs built in to communicate with the user. Key words and sentences that provide instructions or alert the user of the status of the system are symbols. A user is considered computer literate when he or she can understand those symbols. Another way in which a computer system communicates with a user is by means of indices. When a system is turned on or off, a light that indicates the status of the system is an index.
The monitor is likely the most important part of the computer. Without it, you would have no idea what you were doing. Imagine trying to write a term paper, or surf the Internet without one. It would be impossible. While the technology powering the displays doesn’t change as fast as it does for other parts of the computer, there are advances which provide consumers with many choices for displays. Today, the most popular displays come in two types, Cathode Ray Tubes (CRTs) and Liquid Crystal Displays (LCDs). CRTs have been around longer, and are the most common due to the fact that they are cheaper. However the convenient size of LCDs along with falling prices has made them a popular choice as of late. This paper will examine the similarities and differences of the two, and try to determine if one is better than the other.
How hard disk drive works? Firstly we should know the two important parts of the hard disk drive. 1. platters and media. We put all of the data onto the platter. They are inside of the hard drive.
The motherboard is the main circuit board of your computer and is also known as the mainboard or logic board. If you ever open your computer, the biggest piece of silicon you see is the motherboard. Attached to the motherboard, you'll find the CPU, ROM, memory RAM expansion slots, PCI slots, and USB ports. It also includes controllers for devices like the hard drive, DVD drive, keyboard, and mouse. Basically, the motherboard is what makes everything in your computer work together.
What I knew about my computer was how to turn on and off by pressing the big button at the bottom of my computer. I turned on the computer and had no idea what to do next, but I was still happy. I just clicked on everything and did not know how t o go back to the previous screen. Whenever I had problems with my computer, I just turned off the computer. It was pretty simple to clear my computer problems by pressing the power switch. The power switch was a problem solver.
