what are the network types and explain(DCCN-4)

Network types

-The computers are interconnected to information among them which can for mean a computer N/w.
-the computer network type is 3 types:
                                                                 1.LAN(Local area network)
                                                                 2.MAN(Metropolitan network)
                                                                 3.WAN(Wild area network)

LAN(Local area network)

-LAN is usually private own network in which the computers are interconnected in a room or so many in a building or so many building on a campus with in a  specific geographic area depended the on organisation. 
-LAN can be as simple as two computer pointer in some one office and it can extent to through out of the company.  
-now days LAN size is the imitated to few kilometers. 
-LAN are designed to allow resources to be share among them  multiple number of valid user.
-LAN is different for other network by their transmission and topology in a general n/w is coaxial cable and twisted pair cable use in transmission medium.
-the most common topology is the star,bus and ring topology.
-the data rate is 4-10 Mbps of  LAN network.

MAN(Metropolitan area network)

 -The MAN network(metropolitan area network) is the high speed network(broadband) that covers to large geographic area such as city(tens to kilometers).
-These network design is extent over the entire city its may be a single network such as cable television network is may be connection of no of man which is form of long network so resources sharing LAN to LAN and devices to devices.                                                              
-MAN is only own to the own to private company such as telephone network.               


WAN(Wild area network)

WAN is provided to long distance voice.

-Process state means current activity of process. -When process is execute it changes the state generally state of process is determine by the current activity of process. -Each process may be in one of the following state. new- the process is being is oriented. ready- the process is waiting to be assigned to the processor. waiting - the process is waiting for some event (I/O operation) to occur. running - the process is being executed.  terminated -the process as finished the execution. process state diagram: -The pictorial is represented to the process changing from one process to another process during       there  execution is known as process state diagram. -A process can be change for one process in the following manner. new ready: The operating system(os) create a process and prepares the process to be executed ,then the os moved the process into the ready queue.  ready running: When it is time to select a pro...

What is demand paging(OS-9)

Image
Demand paging -Loading the entire program in the physical memory at program execution time is not so good because the user does not need the entire program in memory at a time. -An alternative strategy is to load pages only as they are need this technique is known as demand paging. -With demand paging virtual memory, pages are only loaded when they are demanded during program execution pages that are never accessed thus never loaded into physical memory.    -A demand paging system is a similar to paging system with swapping, -But here it uses a lazy swap where it never swap a pages into memory unless that page will be need. -In demand paging pager is more suitable than swap er.
