1) Differentiate Between NTFS & FAT
1) Differentiate Between NTFS & FAT
1) Differentiate Between NTFS & FAT
NTFS is the current file system used by Windows. It offers features like
security permissions (to limit other users' access to folders), quotas (so
one user can't fill up the disk), shadowing (backing up) and many other
features that help Windows.
FAT32 is the older Microsoft filesystem, primarily used by the Windows 9X
line and Window could be installed on a FAT32 parition up to XP. In
comparision, FAT32 offers none of what was mentioned above, and also
has a maximum FILE (not folder) size of 4GB, which is kind of small these
days, especially in regards to HD video.
2) What Is VOIP.
VOIP - Short for Voice Over Internet Protocol, a category of hardware and
software that enables people to use the Internet as the transmission
medium for telephone calls by sending voice data in packets using IP
rather than by traditional circuit transmissions.
3) What is loop back.
Loopback address is 127.0.0.1,
An address that sends outgoing signals back to the same computer for
testing.
4) What is Proxy Server.
A proxy server is a computer that acts as a gateway between a local
network (e.g., all the computers at one company or in one building) and a
larger-scale network such as the Internet. Proxy servers provide
increased performance and security. In some cases, they monitor
employees' use of outside resources.
5) Differentiate between FIREWALL/ANTIVIRUS.
Antivirus:
The prime job of an antivirus is protect your system from computer
viruses. Your computer may be standalone or part of network or
connected to Internet you need an antivirus program. It actively monitors
when you are using your system for any virus threat from different
sources. if it found one it tries to clean or quarantine the virus ultimately
keeping your system and data safe.
Firewall:
Firewall is in other hand a program which protects your system from
outsider/intruder/hacker attacks. These attacks may not be virus type. In
some cases hackers can take control of your system remotely and steal
your data or important information from system. If your system is directly
connected to internet or a large network than you can install a software
firewall in your PC to protect your self from unauthorized access. Firewall
is available either in software or in hardware form. For a single PC you
may need a software firewall while a large corporate implements
hardware firewall to protect all of their systems from such attacks.
6) Differentiate between Frond end & Back End Server.
Backend server:
A back end server is a computer resource that has not been exposed to
the internet. In this regard the computing resource does not directly
interact with the internet user. It can also be described as a server whose
main function is to store and retrieve email messages.
Frontend server:
A frontend server is a computer resource that has exposed to the
internet.
7) What is APIPA.
Stands for Automatic Private IP Addressing
APIPA is a DHCP fail over mechanism for local networks. With APIPA,
DHCP clients can obtain IP addresses when DHCP servers are nonfunctional.
APIPA exists in all modern versions of Windows except Windows NT.
When a DHCP server fails, APIPA allocates IP addresses in the private
range 169.254.0.1 to 169.254.255.254.
8) How Release and renew IP address from Command prompt.
Ipconfig / release
ipconfig / renew
9) What is wins server.
faster than PATA (IDE) drives. For many years ATA provided the most
common and the least expensive interface for this application. But by the
beginning of 2007, SATA had largely replaced IDE in all new systems.

DHCP:
1) How DHCP work?
DHCP Stands for Dynamic host configuration protocol.
DHCP is a protocol used for automatic configuration IP address in
client computers connected to IP networks. DHCP operates on a
client server model in four phases.
DNS
1) Define DNS .
Domain Name System, DNS is an Internet service that translates domain
names into IP addresses. Because domain names are alphabetic, they're
easier to remember.
Schema Master

Vertualization
1)Define virtualization.
Hyper-V virtualization will provide an environment in which we can run
multiple operating systems at the same time on one physical computer,
by running each operating system in its own virtual machine.
2) What are the benefits of virtualization ?
Reduce the number of physical servers
Reduce the infrastructure needed for your data center
3) What is a Hypervisor.
A hypervisor, also called a virtual machine manager, is a program that
allows multiple operating systems to share a single hardware host. Each
operating system appears to have the host's processor, memory, and
other resources all to itself. However, the hypervisor is actually controlling
the host processor and resources, allocating what is needed to each
operating system in turn and making sure that the guest operating
systems (called virtual machines) cannot disrupt each other.
4) What are a host, guest, and virtual machine.
A host system (host operating system) would be the primary & first
installed operating system. If you are using a bare metal Virtualization
platform like Hyper-V or ESX, there really isnt a host operating system
besides the Hypervisor. If you are using a Type-2 Hypervisor like VMware
