The world’s first computer came out on February 14, 1946, at the University of Pennsylvania in the United States. People called it ENIAC. It covers an area of 147 square meters, weighs 30 tons, and is as high as three floors. We can just call it a monster.
Technology and transistor technology develops. The second generation of computers is coming. Transistor technology is in new design. That makes its volume smaller than that of the first one. The application of integrated circuit technology in intelligent devices is hotter and hotter. The third generation computer developed and produced by IBM came out in 1964. It is the first general-purpose computer family to adopt integrated circuits: IBM360 system. This is a milestone for computers. The new era is coming with the development of large-scale integrated circuit technology. The fourth generation of computers, that is, the personal computer that we use in our daily life, has come out.
Today, the laptops used by many people in their daily life are based on IBM-compatible laptop computer launched by Compaq in November 1982. The first real laptop was the T1100 laptop introduced by TOSHIBA in 1985. Its launch attracted extensive attention from the industry. The development of laptops has started.
Regarding the hardware knowledge of laptops, consumers should have a knowledge of some basic parameter information. What is worth paying attention to is CPU, graphics card, memory and hard disk.
CPU is the core component of the whole laptop. Its performance will affect the running speed of the whole computer. At present, the CPU market in the market is occupied by Intel and AMD. They both have certain advantages and disadvantages. Different computers are equipped with different CPUs. For example, HUAWEI HONOR MagicBook Pro chooses AMD Ryzen 5 4600H processor. Samsung Galaxy Book S is equipped with Intel i5-L16G7 processor.
Graphics cards includes three categories. They are integrated graphics cards, core graphics cards and discrete graphics cards. The main ones on the market are core graphics cards and discrete graphics cards. The core graphics card is integrated into the CPU. Requirements of the basic picture can be met. The performance is poor compared with that of the independent graphics card.
The brand of memory has little influence on the performance of laptops. It depends on capacity and frequency. The capacity should be at least 4G or more to ensure the normal operation and use of the computer. 8G is the commonest for capacity. Hard disks mean solid-state hard disks and mechanical hard disks. Their significance is to store data. Solid state drives can shorten the start-up time and reaction time of laptops. The price is higher. Many laptops on the market contain the combination of solid state disk and mechanical hard disk.
This is some knowledge about laptops.
