Advantages of Using 64-Bit Editions of Windows 7
The 64-bit editions of Windows 7 overcome the application incompatibility issues that affected the 64-bit edition of earlier versions of Windows. The 64-bit drivers are now readily available for most commonly used devices in the 64-bit edition of Windows 7.

Deferences between Master Boot Record (MBR) and Globally Unique Identifier(GUID) Partition Table (GPT) Disk?
The following are common reasons to partition a disk:
1. Separate operating system files from data and user files
2. Place applications and data files in the same location
3. Put cache, log, and paging files in a location separate from other files
4. Create multiboot setup environments
You can use Disk Management to perform disk-related tasks such as creating and formatting partitions and volumes, and assigning drive letters. In addition, you can use the diskpart command, along with other command-line utilities, to perform disk management tasks such as partitioning disks or converting disks from one partition scheme to the other.
What is an MBR Disk ?
The Master Boot Record (MBR) contains the partition table for the disk and a small amount of executable code called the master boot code. A bootable hard disk that contains an MBR is an MBR disk. The MBR is created when the disk is partitioned, is on the first sector of the hard disk, and contains a four-partition entry table describing the size and location of a partition on a disk using 32-bit Logical Block Address (LBA) fields. The size of the partition cannot exceed 2 TB. Most Windows 7 platforms, such as 32-bit and 64-bit SKUs running on motherboards with Basic Input/Output System (BIOS) firmware, require an MBR partitioned system disk and are not bootable with a larger capacity disk.
How MBR-based disks work ?
The MBR is stored at a consistent location on a physical disk, enabling the computer BIOS to reference it. During the startup process, the computer examines the MBR to determine which partition on the installed disks is marked as active. The active partition contains the operating system startup files.
Note: You can install the rest of the operating system on another partition or disk. In Windows 7, the active partition must contain the boot sector, boot manager, and related files.
Features of MBR-based disks
The MBR partition scheme has been around for a long time and supports both current and early desktop operating systems, such as the MS-DOS and the Microsoft® Windows NT® Server 4.0 operating system. Consequently, the MBR partition scheme is widely supported. However, the MBR partition scheme imposes certain restrictions. These include:
1. Four partitions on each disk: MBR-based disks are limited to four partitions. All of these can be primary partitions, or one can be an extended partition with logical volumes inside. You can configure the extended partition to contain multiple volumes.
2. A 2 Terabyte (TB) maximum partition size: A partition cannot be larger than 2 TB.
3. No redundancy provided: The MBR is a single point of failure, and if corrupted or damaged, it can render the operating system non-bootable.
Question: What are three restrictions of an MBR partitioned disk? Have you encountered these limitations in your organization, and if so, what did you do to work around them?
Answer : The restrictions are that MBR partitioned disks are limited to four partitions, a 2 TB maximum partition size, and there is no data redundancy provided.

What is a SUBNET MASK ?
In simple IP networks, the subnet mask defines full octets as part of the network ID and host ID. A 255 represents an octet that is the part of the network ID, and 0 represents an octet that is part of the host ID. In complex IP networks, octets can be subdivided.
Why a subnet mask is required ?
When a computer delivers an IP packet, it uses the subnet mask to validate whether the destination is on the same network or on a remote network. If the destination is on the same network, the packet can be delivered by the computer. If the destination is on the different network, the computer must send the packet to a router for delivery.
To make you understand about subnet mask, I give you a simple example

What Are Public and Private IPv4 Addresses?
Public IPv4 addresses
Public IPv4 addresses must be unique. IANA assigns public IPv4 addresses. Usually, your ISP allocates you one or more public addresses from its address pool. The number of addresses that your ISP allocates to you depends upon how many devices and hosts that you have to connect to the Internet.
Private IPv4 addresses
The pool of IPv4 addresses is becoming smaller, so IANA is reluctant to allocate superfluous IPv4 addresses. Technologies such as Network Address Translation (NAT) enable administrators to use a relatively small number of public IPv4 addresses, and at the same time, enable local hosts to connect to remote hosts and services on the Internet.

What is the differences between Internet Protocol Version IPv4 and IPv6 ?
Limited address space: IPv4 uses only 32-bits to represent addresses. IANA has allocated the majority of these addresses.
Difficult routing management: IANA has not provisioned allocated IPv4 addresses for efficient route management. As a result, Internet backbone routers have over 85,000 routes in their routing tables.
Complex host configuration: Automatic configuration of IPv4 hosts requires that you implement DHCP.
No built-in security: IPv4 does not include any method for securing network data. You must implement Internet Protocol Security (IPSec) and other protocols to secure data on IPv4 networks, but this requires significant configuration and can be complex to implement.
Limited Quality of Service (QoS): The implementation of QoS in IPv4 relies on the use of TCP and User Datagram Protocol (UDP) ports to identify data. This may not be appropriate in all circumstances.

What is Malicious Software ?
Malicious software, such as viruses, worms and Trojan horses, deliberately harm a computer and is sometimes referred to as malware. Spyware is a general term used to describe software that performs certain behaviors such as advertising, collecting personal information, or changing the configuration of the computer, generally without appropriately obtaining consent first. Other kinds of spyware make changes to the computer that are annoying and cause the computer to slow down or stop responding.
There are a number of ways spyware or other unwanted software appears on a computer, including software flaws and some Web browsers. A common method is to covertly install the software during the installation of other software that you want to install. Preventing the installation of malicious software requires that you understand the purpose of the software you intend to install, and you have agreed to install the software on the computer. When you install an application, read all disclosures, the license agreement, and the privacy statement. Sometimes the inclusion of unwanted software is documented, but it might appear at the end of a license agreement or privacy statement.
Consider the following scenario: You are deploying Windows 7 throughout the organization. To decide upon which operating system features to implement, you need to understand security risks that might be relevant to the organization. Take part in a class discussion about this scenario.
Question 1: What are common security risks that you must consider when deploying a new operating system?
Answer
During a desktop deployment, it is important to address any security risks that affect application compatibility, data loss, and user functionality. Some of the more common security risks are categorized as follows:
