Design and build
             Apple's aluminum-and-glass iPhone 5 retains its super-industrial aesthetic, metal buttons and all. Its new, all-metal backing could look slightly less luxe than the iPhone 4S', but it will survive far more drops.We find the GS3's design appealing, but shiny, glossy plastic doesn't scream "quality." That isn't to say that the GS3 is more prone to breaking or shattering than the other two; in fact, plastic has the benefit of scuffing rather than shattering. However, we do really love the GS3's in-hand feel, which is comfortable despite its much larger size.
Our winner so far: Based on looks alone, we're digging the iPhone 5's familiarly crisp lines most, but we also love the Lumia 920's colorful unibody statement.
Camera prowess
This is a tough call since all three phones bring their A-game here. The iPhone has set the benchmark in terms of camera phone performance for quite a while and the improvements to the iPhone 5's imaging system will no doubt cement its lead. These include improved low-light performance and a new panorama shooting mode that catches up to Android.Of course Android devices in many cases surpass the iPhone. Samsung's Galaxy S3 has a sensor that offers the same 8-megapixel resolution as the iPhone 5, plus it features tons of fancy shooting modes like panorama and multishot burst mode.

The Nokia Lumia 920 is the real dark horse in the smartphone camera phone arms race. On paper, its 8.7-megapixel camera and PureView technology promise better performance than both the iPhone and Galaxy S3. It also will be able to run special apps within the camera application itself, allowing you to upgrade its functionality greatly over time -- at least that's the theory.Our winner so far: Though we haven't seen the iPhone 5's camera in action, chances are high that it'll trump the Galaxy S3 since the iPhone 4S matches the GS3 now. Because Nokia's Lumia 920 is still unproven and the Lumia 900's camera wasn't awe-inspiring, we're tempering our hopes with doubts.

LTE and network promise
A this point, LTE on the iPhone 5 was an inevitability, and a feature that's been in the hopper for some time. Verizon has already sworn that all its new smartphones will have LTE, and AT&T and Sprint are expanding their respective networks.Our winner so far: Samsung phones have long been LTE-capable and the Nokia Lumia 920 will be Espoo's second LTE phone. Apple is just now catching up.

Battery life
Nokia plans to equip its Lumia 920 with a 2,000 mAh battery, which should provide a good amount of run time, especially considering that Windows Phone has traditionally been a very economical operating system. Meanwhile, the Samsung Galaxy S3 comes with a slightly larger 2,100 mAh battery that lasted for well over 9 hours playing video. Apple is coy on the iPhone 5's capacity, but promises that its will offer 10 hours of video playback and 8 hours of Web surfing over LTE.Of course, if you're constantly using battery-draining features like S-Voice on the Galaxy S3, or streaming video, no phone will last as long as you'd like.Our winner so far: It's hard to say since we haven't put the Lumia 920 or iPhone 5 to the test, but the Galaxy S3 is a sure bet for most, plus it offers a removable battery.

Wireless Local Area Network (WLAN)

A wireless local area network (WLAN)
A wireless local area network (WLAN) uses radio frequency (RF) technology to transmit and receive data over the air.The Institute of Electrical and Electronics Engineers (IEEE) have established the IEEE 802.11 standard, which is the predominant standard for wireless LANs.Any LAN application, network operating system, or protocol including TCP/IP, will run on 802.11-compliant WLANs as they would over Ethernet

802.11 Standards
The WLAN standards began with the 802.11 standard, developed in 1997 by the IEEE. This base standard allowed data transmission of up to 2 Mbps. Over time, this standard has been enhanced. These extensions are recognized by the addition of a letter to the original 802.11 standard, such as 802.11b.

802.11 b
The 802.11b specification was ratified by the IEEE in July 1999
Radio frequencies in the 2.4 to 2.497 GHz bandwidth of the radio spectrum.
The modulation method selected for 802.11b is known as complementary direct sequence spread spectrum (DSSS) using complementary code keying (CCK) making data speeds as high as 11 Mbps

802.11 a
802.11a operates at radio frequencies between 5.15 and 5.875 GHz.
A modulation scheme known as orthogonal frequency division multiplexing (OFDM) makes data speeds as high as 54 Mbps possible.

802.11 g
802.11g operates at radio frequencies in the 2.4 GHz to 2.497 GHz range (similar to 802.11b), it utilizes the same Orthogonal Frequency Division Multiplexing (OFDM ) modulation allowing for throughput up to 54 Mbps.

Network Requirements
The ease of setting up a WLAN is contributing to its rapid adoption. Reference the following checklist when implementing a new WLAN or expanding an existing WLAN.

Hardware—WLAN consist of two main building blocks including an access point that connects to the network and a wireless adapter installed in the computing device.
Access point—An access point is a small box, usually with one or two antennas. This radio-based, receiver/transmitter is connected to the wired LAN (or broadband connection) using Ethernet cables.
Antennas and bridges—Antennas enhance the radio frequency coverage extending the range of an 802.11 WLAN. Bridges provide point-to-point wireless connection between two LANs, like different floors.
Wireless adapter—A wireless adapter functions like a network interface card (NIC) in that it allows the client computing device access to the network by means of the wireless access point

Security:-
Basic Industry Standard Security: Built into the 802.11b specification, WLAN may be protected by:
Service set identifier (SSID)—A common key that identifies the WLAN. Clients must be configured with the correct SSID to access their WLAN. The key should be shared only with those having legitimate need to access the network so broadcast of SSIDs should be disabled. Also the SSID should be changed periodically.
Media access control (MAC)—Filtering addresses restricts WLAN access to computers that are on a list you create for each access point on your WLAN. This should be enabled.
Wired equivalent privacy (WEP)—Encryption scheme that protects WLAN data streams between clients and APs as specified by the 802.11 standard. This should be turned on.

How to Make Network Cables?

How to Make Your Own Network Cables?

1. Making your own network cable
A network cable basically consists of a patch cable and two network connectors (formally known as RJ45 modular plugs) attached to each of its ends. The job of making your own cable is attaching these connectors to a patch cable.
What you need:
A crimping/cutting/stripping tool: This the most important tool; it helps cut, strip, and crimp patch cable. It costs just about $15. I personally use the Trendnet TC-CT68.
Patch cable: You can buy this in bulk; it costs anywhere between $40 to $100 for 1,000 feet. Shorter length costs less, accordingly. You can also turn an existing network cable into a patch cable by cutting off one or both of its network connector heads. This is typical when you want to make a cable shorter or want to replace a broken network connector.
RJ45 modular plugs: These network connector heads are very cheap; you can get 100 pieces for just a few dollars online.

The steps:
a. Use the tool to strip the patch cable's jacket about 1.5 inch from one end; you'll find eight color-coded wires (twisted into four pairs) that you'll need to arrange in a particular scheme.
This scheme, from left to right, is:
white/orange
solid orange
white/green
 solid blue 
white/blue 
solid green 
white/brown
solid brown.
Remembering this order is the hardest part of making the cable.
 There's no difference in terms of performance between these two wiring standards, and you can also use both of these wiring standards on one cable (one for each end) to make it a crossover cable used to connect two Ethernet-ready devices directly to each other.
b. With these wires pulled out straight and close together in the order above, make sure they are all the same length (you can trim them a bit if need be). Now insert them into a modular plug with the plug's bottom facing you. This step is actually very easy. Despite the small sizes of the parts involved, the plug has pin grooves on the inside to accommodate the wires, and the tiny size means that the wires can't easily go to wrong pins as long as they are properly aligned coming in. Check to make sure the wires go into the plug in the right order.
c. Insert the plug (with the wires now inside) into the crimp slot of the tool and crimp it.
Repeat the same step with another plug on the other end of the patch cable, and you have made yourself a network CAT5e cable. A quick calculation shows that a homemade network cable costs just a few cents per foot.
2. Wiring a wall network port
Now that you know how to make your own network cable, let's talk about how to hide it. As you might imagine, it's not a good idea to run a long cable from the router (in the living room) all the way to the home office, with say, the kitchen in between. Instead, it's better to make two wall network ports, one at the router and the other in the office. The cable connecting these two network ports can be hidden under the floor, on the roof, or behind the wall.
Depending on your home, the actual job of running patch cables behind the wall or under the house, and making both of its ends come out of the wall can be tricky. You might want to hire a handyman for that job, especially the part where you need to cut holes in the wall. In this post, though, I'm just talking about how you can make an Ethernet jack, with the ends of the patch cable already sticking out of the wall. Again, this is a CAT5e jack, also known as a RJ-54 Ethernet jack. A CAT6 jack has the same wiring, however.
What you need:
A punch-down tool: This tool costs about $20. I use a Trendnet TC-PDT, which incorporates a blade to cut off extra wires.
Ethernet jack and wall plate: As many as needed. Generally a set of one jack and one wall plate costs around $5. You can buy these separately and you can find a wall-pate that can house more than one jack.
The steps:
a. Use the stripping tool (or a pair of scissors) to strip the patch cable about 2-inches from its end. You can strip more than 2 inches if need be since the extra length will be cut off, but note that there's a limited amount of patch cable coming out of the wall so you don't want to cut it too short. Spread the 8 wires from one another. There's no need to put them in a particular order since the pins on the Ethernet jack are color coded.
b. Place the cable in the middle of the jack and push its wires on the pins of matching color for the 568B standard. This means that the orange wire goes into the orange pin, the blue wire goes into the blue pin, and so on. Technically, you can use the 568A wiring standard, but in this case you'd need to do the same with the other end. Generally, you want to avoid using 568A for network ports because it could cause problems in the future if somebody else repairs the port and uses the more common 568B standard.
c. Use the punch-down tool to punch these wires down on their pin in one quick motion. If you do it right, the wire will be punched down, and the excessive wires will be cut off.
Now you just need to install the wall plate and you are done with one network port. Now you can make another port at a different end of the house that connects to the port you have just made if you want to have just a single wired connection. For a home with multiple wired connections with devices being far apart, though, you should consider using a patch panel for the other ends of the (hidden) patch cables.
3. Wiring a patch panel.
If you want to have a wired network with many wall network ports coming out in different rooms of the house, it's best to use a patch panel at the central location where the router/switch and/or the home server is. A network patch panel is basically a collection of many wall ports on one panel, with each of the ports connected via a patch cable to another port elsewhere in the house. This allows for easy management of the wired network and better organization.

Configure the domain controller

Domain controllers store data and manage user and domain interactions, including user logon processes, authentication, and directory searches. If you plan to use this server to provide the Active Directory directory service to network users and computers, configure this server as a domain controller.
To configure a server as a domain controller, install Active Directory on the server. There are four options available in the Active Directory Installation Wizard.

Nokia Windows phone 8 launch

                     Nokia unveiled the Lumia 920 and 820 with PureView, its first smartphones using Windows 8 software, in a joint event with Microsoft in New York, at a critical time for both companies.Nokia has finally launched its smart phone handsets powered by Microsoft's Windows Phone 8 operating system. Microsoft and Nokia unveiled the new Lumia 820 and 920 smartphones at a special event in New York.According to the BBC, the new Lumia 920 features wireless charging and a 'PureView' camera, which the mobile firm said offered better video and still images than rival smartphones. It also features several Nokia-only functions designed to make it stand out from other Windows Phone 8 devices.The firm claimed that 'floating lens technology' meant the handset could capture up to 10 times the amount of light than other handsets.
 Design and screen:
The Nokia Lumia 920 has an almost identical physical design as the Lumia 900 before it. This time, the handset comes in Sunshine Yellow, but Nokia will also issue it in Lipstick Red, and Slate Grey.While most of the polycarbonate body remains unchanged, Nokia has improved the screen. The Lumia 920 gets a 4.5-inch Nokia PureMotion HD Plus display, which features a WXGA resolution (1,280x768 pixels), a slightly higher resolution than the standard HD (1,280x720 pixels). It has a fast refresh rate that removes flickers. Nokia also claims it's brighter than rival phones, but we'll have to see about that.

Exchange Servers

Exchange Servers:-
              Microsoft Exchange Server is the server side of a client–server, collaborative application product developed by Microsoft. It is part of theMicrosoft Servers line of server products and is used by enterprises using Microsoft infrastructure products.Microsoft Exchange Server is the brand name for Microsoft's email server software and is typically found in corporations running Microsoft Windows Server. In addition to email Exchange Servers also provide centralized company address books, shared calendars and web browser access.
             

 Versions of Exchange Servers:

Exchange 1.0:-

             Windows Messaging, initially called Microsoft Exchange, is an e-mail client that was included with Windows 95, Windows 98, and Windows NT 4.0.Microsoft Exchange gained wider usage with the release of Windows 95, as this was the only e-mail client that came bundled with it.          

Exchange Server 4.0
                Microsoft began a preliminary planning of the Exchange 4.0 migration in April 1993 and finally all 32,000 Microsoft mailboxes successfully migrated to Exchange and Microsoft Exchange shipped in April 1996.It is upgrade to Microsoft Mail 3.5. The original version of Microsoft Mail (written by Microsoft) had been replaced, several weeks after Lotus acquired cc:Mail, by a package called Network Courier, acquired during the purchase of Consumer Software.
Exchange Server 5.0
                 Exchange Server 5.0 was released on May 23, 1997,which introduced the new Exchange Administrator console, as well as opening up "integrated" access to SMTP-based networks for the first time. Unlike Microsoft Mail ,Exchange Server 5.0 could, with the help of an add-in called the Internet Mail Connector, communicate directly with servers using SMTP. Version 5.0 also introduced a new Web-based e-mail interface called Exchange Web Access, which was re branded as Outlook Web Access in a later Service pack.
Exchange Server 5.5
Exchange Server 5.5 was introduced November 1997, was sold in two editions, Standard and Enterprise. They differ in database store size, mail transport connectors and clustering capabilities.The Standard Edition includes the Site Connector, MS Mail Connector, Internet Mail Service, and Internet News Service , as well as software to interoperate with cc:Mail, Lotus Notes and Novell GroupWise. The Standard Edition had the same 16 GB database size limitation as earlier versions of Exchange Server, while the Enterprise Edition had an increased limit of 16 TB. 
Exchange 2000 Server
Exchange 2000 Server v6.0, released on November 29, 2000, overcame many of the limitations of its predecessors. For example, it raised the maximum sizes of databases and increased the number of servers in a cluster from two to four. However, many customers were deterred from upgrading by the requirement for a full Microsoft Active Directory infrastructure to be in place, as unlike Exchange Server 5.5, Exchange 2000 Server had no built-in Directory Service, and had a dependency upon Active Directory.
 Exchange Server 2003
           Exchange Server 2003 v6.5, debuted on September 28, 2003. Exchange Server 2003  Service Pack 2 can be run on Windows 2000 Server (only if Service Pack 4 is first installed) and 32-bit Windows Server 2003, although some new features only work with the latter. Like Windows Server 2003, Exchange Server 2003 has many compatibility modes to allow users to slowly migrate to the new system. This is useful in large companies with distributed Exchange Server environments who cannot afford the downtime and expense that comes with a complete migration.

               --Connection filtering 
               --Recipient filtering 
               --Sender ID filtering 
               --Intelligent Message Filter
