PPT-Lecture 2-2 Domain Name System

Domain Name System DNS Developed by Postel amp Mockapetris wwwinternicnet is a good site to browse The phone book of the internet But more restrictive Each entry must be Unique Authentic. e LSI Linear shift invariant systems We shall define the term Impulse response in context to LSI systems We shall learn Convolution an operation which helps us find the output of the LTI system given the impulse response and the input signal NOTE I Memory Memory is a property relev ant o nly to systems whose input and output signals have the same independent variable A system is said to be memoryless if its output for each value of the independent variable is dependent only on the input signa DNS is the system that provides name to address mapping for the internet.. Name Space. The names assigned to machines must be unique because the addresses are unique. A name space that maps each address to a unique name can be organized in two ways: . Introduction. There are several applications that follow client server paradigm.. The client/server programs can be divided into two categories:. Those that can be directly used by the user, such as e-mail..
