ai dịch dùm e mấy đoạn chuyên ngành av cntt đi , thanks nhìu

Most input/output devices reside the computer case. These devices communicate with what is inside the computer case through cables attached to the case at a connection called a port, sending data and/or instructions to the computer and receiving them from the computer. Most computers have their ports located on the back of the case, but some models put the ports on the front of the case for easy access. The most popular input devices are a keyboard and a mouse, and the most popular output devices are a monitor and a printer.
The keyboard is the primary input devices of a computer. The keyboards that are standard today are called enhanced keyboards and hold 102 keys. Some keyboards curved to be more comfortable for the hands and wrists, and are called ergonomic keyboards. In addition, some keyboards come equipped with a mouse port – a plug into which a mouse (another input devices) can be attached to the keyboard – although it is more common for mouse port to be located directly on the computer case. Electricity to run the keyboard comes from inside the computer case and is provided by wires in the keyboard cable.

Most applications software fits into eight categories: word processing, spread sheet, database management, graphics, communications, games, mathematical modeling, and software development tools. There are many different products in each software category. For example, some popular database management packages include Access, Paradox, and Film make, and two popular word – processing packages include Word and WordPerfect.
Some applications software manufacturers are producing suites of software, which combine a word – processing program and spreadsheet program, and usually include a database management program, a presentation package, an e – mail package, and a Word Wide Web browser package. Suites provide many advantages, including the fact that the programs tend to use the same basic instruction sets; the programs are designed to make it easy to move data from one suite program to another; and files within a suite’s programs can be linked, so that updates to data or text are automatically recorded in all linked files.

It is common practice in computer science for the words “computer” and “processor” to be used interchangeably. More precisely, “computer” refers to the central processing unit (CPU) together with an internal memory. The internal memory or main storage, control and processing components make up the heart of the computer system. Manufactures design the CPU to control and carry out basic instructions for their particular computer.
The CPU coordinates all the activities of the various components of the computer. It determines which operations should be carried out and in what order. The CPU can also retrieve information from memory and can store the results of manipulations back into the memory unit for later reference.
In digital computer the CPU can be divided into two functional units called the control unit (CU) and the arithmetic – logical unit (ALU). These two units are made up of electronic circuits with millions of switches that can be in one of two states, either on or off.
The function of the control unit within the central processor is to transmit coordinating control signals and commands. The control unit is that portion of the computer that directs the sequence or step – by – step operations of the system, selects instructions and data from memory, interprets the program instructions, and controls the flow between main storage and the arithmetic – logical unit.
