English names of common hardware and equipment

CPU: the central processing unit, which is the central processing unit.

 

Ram: Random Access Memory, random memory, which is commonly referred to as "Memory ".

ROM: read-only memory, read-only memory.

Edo: extended data output. When the processing speed of the CPU continues to increase, it is also required to continuously increase the speed of DRAM data transmission. Generally, the speed of data transmission by FPM (fast page model) DRAM is at 60-70 ns, edo DRAM is 3 times faster than FPM, reaching 20 NS. Currently, the fastest access speed is SDRAM (synchronous DRAM, synchronous dynamic memory), and its access speed is as high as 10 ns.

SDRAM: synchronous dynamic random access memory, synchronous dynamic random memory, also known as synchronous DRAM, is a new generation of dynamic memory. It can use the same clock as the CPU bus. Therefore, compared with the Edo memory, the SDRAM memory can greatly improve the computer performance.

Cache: "(exploration personnel and other food and equipment storage ". High-speed buffer memory in the computer is located between the CPU and the primary Memory DRAM (Dynamic Randon Access Memory). The memory is small but fast, it is usually composed of static random access memory static memory.

CMOS: Abbreviation of Complementary Metal Oxide semicondu. it refers to a complementary metal oxide semiconductor (referred to as a complementary metal oxide semiconductor memory ). CMOS is a battery-powered memory (RAM) used in most computers ). It is an important tool for determining the hardware configuration of the system, optimizing the overall performance of the microcomputer, and maintaining the system. It stores information about system hardware settings. After the system is shut down, the information continues to exist (which is totally different from Ram ). This information is required for the computer to start the system. If the information retained in CMOS is messed up accidentally or accidentally, the computer system cannot start properly.

PCI: Peripheral Component interconnection, a local bus (bus is the high-speed channel used by a computer to transmit information from one device to another ). PCI bus is a more advanced bus structure. Its functions are much better than those of other bus. It can be used to support the sticky-ysh of the delayed-ring hybrid column bed? 32 Mbps, one of the fastest data transmission bus, supports multiple groups of peripheral devices at the same time. PCI is not subject to CPU processors, and is compatible with various existing buses. The size of the Main Board slots is small, so the cost is low, which is conducive to promotion.

Seagate: US Seagate hard drive manufacturer. The English meaning of Seagate is "the portal to the Ocean", which usually refers to the canal of the sea.

Quantum: The English meaning is "quantitative, total ". The famous hard drive trademark is quantum Corporation ).

Maxtor: "Crystal", an American maxtor hard drive company.

Ld: laser disk, which is also called a laser video disk.

CD: compact disc, compression disc, also known as a laser recording disk.

CD-ROM: compact disc-read only memory, compressed disc-read-only memory (storage), also known as "Read-Only disc ".

VCD: video compact disc, a compressed video disc, which is commonly referred to as a "small album ".

DVD: many people regard it as the abbreviation of digital video disc. In fact, from September 1995, after the two major DVD development groups Sony/Philips and Toshiba/Time Warner have reached a unified DVD standard, the meaning of the DVD has changed a lot and it has become a universal digital CD, that is, the abbreviation of digital versatile disc. Versatile's "general" meaning indicates the diversified usage of DVDs. It can be used not only in film and entertainment, but also in multimedia computer and other fields. At present, according to its use can be divided into five types: 1, computer read-only disc-DVD-ROM; 2, home-type audio and video disc-DVD-movie; 3, dedicated for Music Appreciation of the DVD Audio; 4, write only one disc-DVD-R; 5, can read and write multiple disc-DVD-Ram.

Modem: a necessary tool for the Internet (Internet) Network on a modem and home computer. The word modem cannot be found in the English-Chinese dictionary. It is a modem) and demodulator. Modem is an essential external device for computer communication. Because the data of a computer is a digital signal, it is intended to be transmitted over a transmission line (such as a telephone line) to another computer or other terminal (such as a telex typewriter) at a long distance ), digital signals must be converted to analog signals (modulated signals) suitable for transmission ). The receiver must recover the received analog signal to the original digital signal, which requires the use of a modem.

UPS: Short for uninterruptible power supply (uninterruptible power supply. It emerged along with the birth of the computer and is one of the important peripheral devices of the computer. UPS is a constant-voltage, constant-frequency, uninterrupted power supply consisting of inverters. It is used to protect computers from losing important data during sudden power outages.

TFT: an active matrix color display, or TFT display, used in laptops. TFT display has the advantages of fast refresh speed, vivid color, and clear brightness. In addition, it also has no flickering, no radiation, no static electricity and other "Green Computer" necessary features.
