Registers are high-speed internal memory-storage units within the CPU. Some registers are user-visible; that is, available to the programmer via the machine instruction set. Other registers are dedicated strictly to the CPU for control purposes. An internal clock synchronizes all CPU components.

What is a port of the CPU?
In computer terms, a port generally refers to the part of a computing device available for connection to peripherals such as input and output devices. Computer ports have many uses, to connect a monitor, webcam, speakers, or other peripheral devices.
What is the purpose and function of a computer central processing unit?
A central processing unit (CPU), also called a central processor, main processor or just processor, is the electronic circuitry that executes instructions comprising a computer program. The CPU performs basic arithmetic, logic, controlling, and input/output (I/O) operations specified by the instructions in the program.
What is communication port?
Alternatively referred to as the com port, the communications port is a serial communication used to connect devices such as your modem. Usually, communication ports are designated as COM1, COM2, COM3, and COM4 on computers running Microsoft Windows.
What is the importance of port in computer system?
Ports provide the input and output interfaces the device needs to communicate with peripherals and computer networks. The most important ports on computers are used for networking, for without them, the computer would be completely isolated and unable to communicate outside of itself.
What is the 10101 port for?
Serial port pin information
With many computers, the serial port is labeled as "10101" which are ones and zeros to represent binary. ... Most of today's computers are eliminating the serial port in favor of USB ports.
What are the three types of ports?
The port numbers are divided into three ranges: the well-known ports, the registered ports, and the dynamic or private ports. The well-known ports (also known as system ports) are those numbered from 0 through 1023.
What best describes of central processing unit?
The central processing unit (CPU) or processor, is the unit which performs most of the processing inside a computer. It processes all instructions received by software running on the PC and by other hardware components, and acts as a powerful calculator.
What does the central processing unit consists of?
The central processing unit (CPU) is the core of a computer system and consists of the arithmetic logic unit (ALU) and the control unit. The ALU can come in a variety of configurations—from a single simple unit, up to extremely complex units that perform complex operations.
What is garbage in garbage out GIGO?
GIGO (garbage in, garbage out) is a concept common to computer science and mathematics: the quality of output is determined by the quality of the input. ... A variation on the term, "garbage in, gospel out," refers to a tendency to put unwarranted faith in the accuracy of computer-generated data.
What is my port?
All you have to do is type “netstat -a” on Command Prompt and hit the Enter button. This will populate a list of your active TCP connections. The port numbers will be shown after the IP address and the two are separated by a colon.
How do ports work?
Ports work the same way. You have an IP address, and then many ports on that IP address. ... When a program on your computer sends or receives data over the Internet it sends that data to an ip address and a specific port on the remote computer, and receives the data on a usually random port on its own computer.
What E is describes the way a port receives communication?
There are also registered ports, which organizations or software producers have registered for their applications. The Internet Assigned Numbers Authority (IANA) is responsible for registration. There is also a wide range of port numbers that are assigned dynamically.
Why having more ports and slots are important in a motherboard?
Computers have expansion slots to give the user the ability to add new devices to their computer. For example, a computer gamer may upgrade their video card to get better performance in their games. An expansion slot allows them to remove the old video card and add a new video card without replacing the motherboard.
What is the D ++ port?
DisplayPort looks similar to HDMI but is a connector more common on PCs than TVs. It still allows for high-definition video and (in many cases) audio, but its standards are a bit different. ... DisplayPort 1.2: Supports up to 4K at 60Hz, some 1.2a ports may also support AMD's FreeSync.
What is parallel port used for?
See parallel interface. (2) A socket on a computer used to connect a printer or other device via a parallel interface (eight data bits transferring simultaneously). In the past, the parallel port was widely used for printers and occasionally for connecting other devices externally, but was superseded by USB.
What rs232 port is used for?
An RS-232 serial port is most often used by repair technicians to perform diagnostics and service updates. It may also be used to control a device when connected to a computer running a home automation system or Custom Integrated Audio/Video (A/V) system, such as the CAV-M1000ES Multi-room A/V Distribution System.
