Main performance indicators: 1. Word length refers to the number of binary data bits that the CPU can directly process. It is directly related to the calculation accuracy, function and speed of the computer; 2. Operation speed refers to the number of seconds the computer can process per second. The number of instructions that can be executed is an important indicator of computer performance; 3. The main frequency refers to the number of pulses sent by the computer's CPU in unit time, which largely determines the running speed of the computer; 4 , Memory capacity reflects the computer's ability to store information instantly. The larger the memory capacity, the more powerful the system function, and the larger the amount of data it can process.
The operating environment of this tutorial: Windows 7 system, Dell G3 computer.
Computer, commonly known as computer, is a modern electronic computing machine used for high-speed calculations. It can perform numerical calculations, logical calculations, and also has storage and memory functions. It is a modern intelligent electronic device that can run according to the program and process massive data automatically and at high speed.
The main technical performance indicators of the computer
1. Word length:
The computer is in the same A set of binary numbers processed within a time period is called a "word" of a computer, and the number of digits in this set of binary numbers is the "word length". The word length is the number of binary data bits that the CPU can directly process. It is directly related to the calculation accuracy, function and speed of the computer. The longer the word length, the stronger the processing power. Common microcomputer word lengths are 8 bits, 16 bits and 32 bits.
#When other indicators are the same, the larger the word length, the faster the computer processes data. The word lengths of early microcomputers were generally 8 and 16 bits. Currently, most 586s (Pentium, PentiumPro, PentiumII, PentiumIII, Pentium4) are 32-bit, and most people now have 64-bit installed.
2. Operation speed:
The operation speed refers to the number of instructions that the computer can execute per second, generally in MIPS.
Operation speed is an important indicator of computer performance. The commonly referred to computer computing speed (average computing speed) refers to the number of instructions that can be executed per second, which is generally described as "million instructions/second" (mips, MillionInstructionPerSecond).
The same computer may take different times to perform different operations, so different methods are often used to describe the operation speed. Commonly used ones include CPU clock frequency (clock frequency), average number of instructions executed per second (ips), etc. Microcomputers generally use the main frequency to describe the computing speed. For example, the main frequency of Pentium/133 is 133 MHz, the main frequency of Pentium III/800 is 800 MHz, and the main frequency of Pentium 41.5G is 1.5 GHz. Generally speaking, the higher the main frequency, the faster the computing speed.
3. Main frequency:
The main frequency is the clock frequency, which refers to the number of pulses sent by the computer's CPU in unit time. It largely determines how fast your computer runs. The unit of main frequency is megahertz (MHz), and the most common one nowadays is gigahertz (GHz).
4. Internal memory capacity:
The performance indicators of memory mainly include storage capacity and access speed.
Internal memory, also referred to as main memory, is a memory that the CPU can directly access. Programs that need to be executed and data that need to be processed are stored in the main memory. The size of internal memory reflects the computer's ability to store information instantly. With the upgrade of operating systems, the continuous enrichment of application software and the continuous expansion of functions, people's demand for computer memory capacity is also constantly increasing. Currently, running the Windows95 or Windows98 operating system requires at least 16M of memory capacity, while WindowsXP requires more than 128M of memory capacity. The larger the memory capacity, the more powerful the system is and the larger the amount of data it can handle.
5. CPU frequency:
CPU is the most important factor that determines the performance of a laptop. Computer computing speed refers to The number of instructions that a computer can execute per second, that is, the average number of times the central processor runs per unit time.
