More fun with your laptop

Posted on April 6, 2010, 2:52 pm

A laptop is a personal computer designed for mobile use and small and light enough to sit on the lap of a person in use. [1] A portable computer incorporates many elements of a typical desktop computer, including monitor, keyboard, pointing device (a touchpad, also known as a trackpad, and / or a pointing stick) , speakers, and often including a battery, into a single unit small and light. The rechargeable battery (if present) is charged from an AC adapter and generally stores enough energy to power the laptop for two to three hours in its original state, depending on the configuration and management of power of the computer. 1. Laptop Processors: The microprocessor or CPU, works with the operating system to control the computer. It essentially acts as the brain of the computer. The CPU produces a lot of heat, so a desktop computer uses circulating air, a fan and heat sink – a system of plates, channels and radiator fins used to draw heat off the processor – for cool. Since a laptop can hold much less for each of these cooling methods, its CPU usually: i) operates at a lower voltage and clock speedii) mounted on the motherboard without using pinsiii) Has a sleep mode or slow 2. Laptop Memory and Memory: A portable computer can compensate for some of the reduced performance that comes from a slower processor. Some laptops have cache memory on or very near the CPU, allowing it to access data faster. Some also have more bus, allowing data to flow between the processor, motherboard and memory more quickly. Lapto ps often use smaller memory modules to save space. types of memory used in portable computers: i) Small Outline Dual Inline Memory Module (SODIMM) ii) Double Data Rate Synchronous RAM (DDR SDRAM) iii) Single Data Rate Synchronous RAM (SDRAM) iv) Owner memorymodules AREL < = “nofollow” onclick = “javascript: pageTracker. _trackPageview (‘/ outgoing / article_exit_link’);” href = “http://www. freecouponsbuzz. com” www “. freecouponsbuzz. com </ a> 3. Portable screen, graphics and sound: A graphics processing unit (GPU) is a microprocessor that manages the calculations necessary for 3-D graphics rendering. As a processor, a GPU produces a lot of heat. Most laptops have graphics capability built into the motherboard or smaller graphics cards with a GPU designed specifically for portable use. GPU manufacturers ATI and nVidia are both GPUs specifically for laptops. portable memory is often shared between the CPU and the GPU, saving space and energy consumption reduction. A laptop display its graphics on a liquid crystal display (LCD). Most screens are between 12 and 17 inches, and the size of the screen affects the overall size of the laptop. 4. Batteries: laptops and desktops in both electricity. Both have small batteries to maintain the real time clock and, in some cases, the CMOS RAM. However, unlike a desktop, a laptop is portable and can run on batteries alone. 5. Whitebook: A laptop or at home is called WhiteBook modded. Whitebook represent about 5 percent of the notebook market right now, and this number increases gradually. The industry has done a very good job of keeping the end users of portable computers. They have made it difficult to open, edit and get parts for a laptop. In addition, the opening of the portable frame voids the manufacturer’s warranty in most cases. 6. Keep your laptop: Always take care when connecting to a wireless network open. Install a solid firewall, like Zone Alarm, and make sure you set its security level settings for optimal protection. Sharing files on an open network is just asking for trouble, so make sure you enable this setting and others it off.
