What is a computer terminal? What is a frame in a computer

So far, computing technology has gone through three development periods: the mainframe era, the PC era, and the network computing era. Terminals have adapted to the three stages of computing technology development, and applications have also gone through three forms: character dumb terminals, graphic terminals, and network terminals. People's work, life, and study are increasingly inseparable from computers. So today we will discuss what is a computer terminal? What is a frame in a computer? Let's learn more about it.

What is a computer terminal

Terminal, or computer display terminal, is the input and output device of the computer system. Computer display terminals were born with the centralized processing mode of the host era, and have continued to develop with the development of computing technology. So far, computing technology has gone through three development periods: the host era, the PC era, and the network computing era. Terminals are adapted to the three stages of computing technology development, and applications have also gone through three forms: character dumb terminals, graphic terminals, and network terminals. Currently, common client devices are divided into two categories: one is fat client and the other is thin client. Then, the devices represented by PCs that are based on open industrial standard architecture and have relatively powerful functions are called "fat clients", and the others are classified as "thin clients". The space and scale of the thin client industry are also very large, not less than the current scale of PCs.

What is a frame in a computer

Frame is the abbreviation of the number of frames generated. Due to the common usage, we usually confuse the number of frames with the frame rate. Each frame is a still image, and displaying frames in rapid succession creates the illusion of motion, so a high frame rate can produce smoother and more realistic animations.

The naked eye will think that static images with more than 24 frames per second are continuous dynamic videos, so you can shoot a video at 60 frames per second, and then adjust the frame rate to about 24 frames per second through software. Then the image you shot in one second can be played back in slow motion to two seconds, and it will be continuous and not stuck. If you can shoot a video at 90 frames per second, then you can at least slow down one second to three seconds of slow motion playback, and so on. High-speed video can capture many details and wonderful moments that we tend to overlook. Playing videos in slow motion will also make the videos more fun and interesting. This is why more and more manufacturers are beginning to pay attention to the high-speed video function.

What is a computer job title?

Computer professional titles are titles that demonstrate computer capabilities.

The national professional title computer examination can improve the popularization and application of computers and the Internet, strengthen the development and utilization of information resources, implement the national requirements for accelerating informatization construction, guide professional and technical personnel across the country to learn and master computer knowledge, and improve their computer application capabilities. According to the "Notice on the National Professional and Technical Personnel Computer Application Ability Examination" of the former Ministry of Personnel, starting from 2002, the professional and technical personnel computer application ability examination was promoted nationwide, and the examination results were used as one of the conditions for the evaluation and appointment of professional and technical positions.

The programs that can be directly executed by the computer are

Machine language program. The program that a computer can directly execute is a machine language program. Machine language is a program language or instruction code that a machine can directly recognize without translation. Each opcode has a corresponding circuit inside the computer to complete it, or it refers to a program language or instruction code that can be directly understood and accepted by the machine without translation. Machine language uses absolute addresses and absolute opcodes. Different computers have their own machine languages, that is, instruction systems. From the perspective of use, machine language is the lowest level language.
