A computer networking IT is a set
of devices connected through links. A node can be computer, printer, or any
other device capable of sending or receiving the data. The links connecting the
nodes are known as communication channels.
Computer Network uses distributed processing in
which task is divided among several computers. Instead, a single computer
handles an entire task, each separate computer handles a subset.
Following
are the advantages of Distributed processing:
- Security: It provides limited interaction that a
user can have with the entire system. For example, a bank allows the users
to access their own accounts through an ATM without allowing them to
access the bank's entire database.
- Faster problem solving: Multiple computers can
solve the problem faster than a single machine working alone.
- Security through redundancy: Multiple computers
running the same program at the same time can provide the security through
redundancy. For example, if four computers run the same program and any
computer has a hardware error, then other computers can override it.
A computer network
is a group of two or more interconnected computer systems. You can establish a
network connection using either cable or wireless media.
Every network
involves hardware and software that connects computers and tools.
