yi yi yi yi yi yi yi yi yi yi yi yi yi yi yi yi yi yi
gateway IP, subnet mask, DNS server IP. It can be used to communicate with the other PCs in the
yi yi yi yi yi yi yi yi yi yi yi yi yi yi yi yi yi yi yi
network. The superscope becomes when you combine two or more scopes together.

yi yi yi yi yi yi yi yi yi yi yi yi yi yi yi yi
understand the number and not the alphabet. For example, if we type like hotmail.com, the computer
yi yi yi yi yi yi yi yi yi yi yi yi yi yi yi yi
doesn't understand this, so they use DNS which converts (hotmail.com) into (numbers) and then
yi yi yi yi yi yi yi yi yi yi yi yi yi yi
executes the command.

yi yi yi yi yi yi yi yi yi yi yi yi yi yi yi yi yi yi yi
record, and it can map the IP address by name. It is with this record that DNS can find out the IP
yi yi yi yi yi yi yi yi yi yi yi yi yi yi yi yi yi yi yi yi yi yi
address of a name. While, 'MX record' also known as mail exchanger record, by the help of 'MX' record,
yi yi yi yi yi yi yi yi yi yi yi yi yi yi yi yi yi yi yi
location of the mail server is identified. The record is also found in DNS.

yi yi yi yi yi yi yi yi yi yi yi yi yi yi yi yi yi yi
the internet. It can be used by centrally administer computers. It is created when you install active
yi yi yi yi yi yi yi yi yi yi yi yi yi yi yi yi yi
directory.

10) Tell me if your system is infected by a virus how you will recover the data? - (correct answer) -You
yi yi yi yi yi yi yi yi yi yi yi yi yi yi yi yi yi yi yi yi
need to install another Hard Disk with the latest anti-virus software, and an O.S with latest patches.
yi yi yi yi yi yi yi yi yi yi yi yi yi yi yi yi yi
Before you start your system, connect the infected HDD as a secondary drive then scan and clean the
yi yi yi yi yi yi yi yi yi yi yi yi yi yi yi yi yi yi
infected hard drive. Once done, you can copy the files into the system.
yi yi yi yi yi yi yi yi yi yi yi yi yi
11) What is the operating system? - (correct answer) -Operating system acts as an interpreter between
yi yi yi yi yi yi yi yi yi yi yi yi yi yi yi
computer application and hardware. It works as a user interface.
yi yi yi yi yi yi yi yi yi yi
, 12) What are the types of the operating system or O.S? - (correct answer) -The two types of operating
yi yi yi yi yi yi yi yi yi yi yi yi yi yi yi yi yi yi
systems are:

yi yi yi yi yi yi yi yi yi yi yi yi yi yi
operating the tool or information that typically resides on a network or IT devices through a
yi yi yi yi yi yi yi yi yi yi yi yi yi yi yi yi
combination of hardware and software, for example connecting to a printer or file. It is usually used for
yi yi yi yi yi yi yi yi yi yi yi yi yi yi yi yi yi yi
mobile users who are in the network. It uses a telephone line to provide connectivity to its users. It can
yi yi yi yi yi yi yi yi yi yi yi yi yi yi yi yi yi yi yi yi
also connect two or more than two offices in the network.

in the network. It can be used to define a user's security and networking policies. By group policy, you
yi yi yi yi yi yi yi yi yi yi yi yi yi yi yi yi yi yi yi
can keep control over certain function like not allowing the users to shut down the system or using the
yi yi yi yi yi yi yi yi yi yi yi yi yi yi yi yi yi yi yi
control panel or running the command. Group policy is applicable to active directory containers like
