 Definition of computer ports and types of ports

What is the definition of Ports : 

A port is a physical docking point using which an external device can be connected to the computer. It is important because information flows from a program to the computer or over the intern ate.  A port is a interface between the computer and other computers or peripheral devices. Two types of computer are used in the computers which are known as internal port and external port. 

Internal ports are connects to the internal devices such as  hard drives, DVD drives. External port are connect to the external devices such as modem, printers and many other external devices.

Characteristics of ports : A port has the following characteristics 

  1. External devices are connected to a computer using cables and ports.
  2. Ports are interface between external device as well as a computer.
Types of computer ports :
  1. PS/2 port
  2. VGA port
  3. Modem port
  4. Ethernet port
  5. HDMI port
PS/2 port : PS/2 port is stands for personal system/2 it is also known as the mouse port or keyboard port . It is used to connect mouse or keyboard to motherboard and it is developed by IBM.

VGA port(Video Graphics Array (adapter) ) : VGA port is used to connect monitor to a computer motherboard. It is also use to connect projector and Television sets. 

Modem port : Modem port is also known as phone connector, phone jack or phone jack. It is used to connect a computer modem to the telephone network.    

Ethernet port : Ethernet port is used to to connects the network cable to a computer and we can say that it used to connect to a network and high speed inter networking.
Ethernet port is also known as network connection port, LAN port and network port.

HDMI port (High definition multi) : The HDMI technology is used with devices such as projectors and DVD player. A single HDMI port replace the three composite audio/video cables, making it easier to connect two devices together for transmitting audio and video signals.

Deadlock in operating system-computer world

  Deadlock in operating system-computer world Deadlock :  In a multi-programming environment, many process may complete for a minute number of resources. A process make a request for a resource and if the resource is not available at that time, the process enter In a waiting state. A waiting state process is never again-able to change state because the resource it has requested is held by other waiting process. This situation is called deadlock. So we can say that a process is said to be deadlock when it is waiting for an event or resources which will never occurs.   so we can say that in this situation none of the process gets executed  since the resource it needs, is held by some other process which is also waits for some other resource to be released.  Let's assume that there are three process P1, P2, p3 and three different resources R1, R2 and R3. R1 is assigned to p1, R2 is assigned to P2 and R3 is assigned to P3.   After somet...

Memory management in operating system-computer world

Memory management in operating system-computer world Memory management :   The function of operating system which manages the memory of a computer for the processing of the program this management is known as memory management. There are several programs that consist in memory, so it became to move programs and data around the memory of a memory management system is the collection of hardware and software procedures for the Managing various program consisting in the memory. Memory management play an important role in operating system to improve the speed speed of the computer system.   Memory management determines how  memory is allocated between the processes,  deciding which gets memory, when they receive it and how much they are allowed. When memory is allocated it determines which memory location will be assigned. Main memory refers to a physical memory that is the internal memory of the computer. Main memory is also known as RAM. The computer is able t...
