Computer Performance
Factors those affect computer performance
There are a wide range of factors that can affect the performance of your computer. These include CPU speed, RAM size, type of graphics card processor and memory plus the number of applications running. It is important to realist that it is not just the speed of the CPU that affect the overall performance of your computer. There is no point in having a very fast CPU if the other parts of a computer may slow down the real world performance.
CPU speed
The computer speed or better say the processor speed governs how fast the CPU will run. The higher the speed the faster the computer will work for you. The speed is given in Gigahertz (GHz). The higher the GHz speed the faster the computer.
RAM size
Computer keeps all its working files in RAM while working. So the larger the RAM size is, the more
comfortable and faster computer can perform. Like, if a person has a large table top space he will be able to work easily on many files open at a time.
Graphics card processor and memory
To display what user wants, computer uses its graphics card. If the graphics card memory is a little bit lower than the graphics card shares the RAM to complete its task. While a portion of the RAM is used to display things, the user is not getting the RAM at its full performance. As a result, affecting on the computer’s performance.
Number of applications running
Windows is a multitasking system, which means that it can run more than one program at a time. However the more programs which are running at the same time, the slower each one will run. To some extent this slowing effect depends on what each program is doing. Editing a large high definition video for instance can take up a lot of CPU time.
MHz and GHz
MHz is short form Mega Hertz and GHz is short form of Giga Hertz. Hertz is usually the unit of frequency measurement. It indicates the speed of the computer’s CPU or of any other component whose performance is given in terms of frequency. Generally, higher Hertz indicates faster performance
1 MHz = 1,000,000 Hertz (1 million Hertz)
1GHz = 1,000,000,000 Hertz (1 billion Hertz)
CPU speeds
The speed (operating frequency) of the CPU is measured in megahertz (MHz) or gigahertz (GHz). The higher the value the faster the CPU will operate. The original IBM PC released way back in 1981 ran at 4.77 MHz whereas modern PCs can run at over 4000 MHz, which gives you an idea of how far things have progressed. 1 MHz means that the device will run at one million cycles per second. 1 GHz is a thousand times faster, so that 1 GHz = 1000 MHz.
