Top 10 Windows 8 tips and tricks

Update to Windows 8.1

Microsoft has released Windows 8.1, which is a free upgrade for anyone running Windows 8. This update addresses many of the problems users have had with Windows 8 and also adds a Start button. Visit Microsoft's Windows 8.1 page for the update.

Customize your tiles


Make the most of your Windows Start screen tiles by adjusting the sizes, where they are located, and what is listed.
  • Move any tile by clicking and dragging the tile. While moving a tile, if you need a larger view of the Start screen move the tile towards the top or bottom of the screen to zoom out.
  • Use your mouse wheel to scroll left-to-right through your tiles.
  • Any Desktop shortcut or program can be pinned to the Start screen by right-clicking the icon and choosing Pin to Start.
  • In the bottom right-hand corner of the start screen is a magnifying glass with tiles, click this icon to get a zoomed out view of your Start screen. In this view, if you right-click on a group of tiles you'll be given the option to name group, which can be useful if you have a group of related tiles (e.g. games). In this view, you can also click and drag a group to organize your tile groups.
  • Create a new speed bump between tile groups by moving a tile to a speed bump.
  • Resize any User tile or Live tile by right-clicking the tile and choosing resize.
  • If there is a tile you want on your Taskbar, right-click the tile and choose Pin to taskbar.
  • Show admin applications on the Start screen by clicking Settings in Charms, click Settings, and change the Show administrative tools from No to Yes.
  • In Internet Explorer 10, you can also pin any of your favorite web pages to your Start Screen.

Windows 8 keyboard shortcuts

Knowing at least some of the Windows 8 keyboard shortcuts helps make your Windows 8 experience much more enjoyable. Try to memorize these top Windows 8 shortcut keys.
  • Press the Windows key to open the Start screen or switch to the Desktop (if open).
  • Press the Windows key + D opens the Windows Desktop.
  • Press the Windows key + . to pin and unpin Windows apps on the side of the screen.
  • Press the Windows key + X to open the power user menu, which gives you access to many of the features most power users would want (e.g. Device Manager and Command Prompt).
  • Press the Windows key + C to open the Charms.
  • Press the Windows key + I to open the Settings, which is the same Settings found in Charms.
  • Press and hold the Windows key + Tab to show open apps.
  • Press the Windows key + Print screen to create a screen shot, which is automatically saved into your My Pictures folder.
See our Windows shortcuts page for a full listing of all Windows shortcuts.

Know your hot corners

The corners on your screen are hot corners and give you access to different Windows features. Below, is a brief explanation of each of these corners.
Bottom Left-hand corner
The bottom left-hand hot corner of the screen allows you to access the Start screen. If you're in the Start screen and have the Desktop open, this corner opens the Desktop from the Start screen.
Tip: Right-clicking in the left hand corner opens the power user menu.
Top-left corner of the screen
Moving the mouse to the top-left corner and then down displays all the apps running on the computer. Clicking and dragging any of these apps to the left or right-hand side of the screen will snap that app to that side of the screen. Each of these open app icons can also be right-clicked to close or snap.
Right-hand side of the screen
On the full right-hand side of the screen will be given access to the Windows Charms.

Taking advantage of search

The Search in Windows 8 has been significantly improved when compared to all previous versions of Windows. To search for a file or run a program in Windows 8 from the Start screen just start typing what you're trying to find or want to run.
As you begin typing, the results will start appearing on the left-hand side. The Search also supports limiting the search to apps such as Finance, People, Maps, Photos, Mail, Music, Videos, Weather, and much more. If what you are searching for is not a file or program, click on the app you want to use as the search. For example, if you were searching for "New York" and selected the Weather App you would be shown the weather in New York, NY.
By default, Search organizes the available Apps by how frequently they are used and then in alphabetical order. If you want to keep your favorite app at the top of the Search list, right-click the app and choose Pin. Pinning the app will lock it in place regardless of how often it is used. If there is an app you don't want (e.g. Finance) you can turn on and off any of the search apps through the PC settings, which is found under the Settings in the Charms.
Bonus tip: The Search is also found through Charms and can also be opened by pressing Windows key + F.

Running two apps side by side

Any app can be pinned to the left or right-hand side of the screen. For example, open the People app and then press the Windows Key + . (period) to move that app to the right-hand side of the screen, pressing the same keys again will move it to the left-hand side, and pressing the same keys again makes it full screen. While an app is pinned, any other app or program can be opened and loaded into the available space on the screen. For example, in the picture below, we've opened a browser window and have the People app running to monitor our social networks.
Any open app can also be pinned using your mouse by clicking at the top of the tile and dragging it to the left or right-hand side of the screen.
Bonus tip: The Desktop can also be pinned to the left or right-hand side of the screen.
Note: For snap to work properly your resolution must be at least 1,366 x 768.

Windows 8 Task Manager

The Windows 8 Task Manager has been significantly improved over previous versions of Windows. Some of the changes include a total percent usage of your Processes, improved Performance graphs, a Startup tab to see startup processes, and the App history tab (as shown below) for total resources an app. Press Ctrl + Shift + Esc to start exploring the new Task Manager.

Use a picture password to log into your computer

Windows 8 includes a new feature called Picture password, which allows you to authenticate with the computer using a series of gestures that include circles, straight lines, and taps. Enable this feature if you want a new way to access your computer or have a hard time with passwords.
  1. Open the Windows Charms.
  2. Click Settings and then More PC settings
  3. In the PC settings window click Users and then select Create a picture password
Bonus tip: A four digit pin password can also be created and used to access your computer.

Take advantage of Windows 8 apps

Windows 8 comes included with several apps to help you get the most from your computer. Below are just a few of the included apps.
People
Microsoft touts the People feature in Windows 8 because they understand how many people are using social networks today. In the People feature you'll be able to connect your Windows computer to all the major social networks including FacebookLinkedIn, and Twitter. Once connected, you can pin the people app and monitor your social network (as shown below), use People in Search to find people, and get an overview of what is happening in all your social networks.
Reader
The Reader app gives you PDF support right out of the box.
SkyDrive
The SkyDrive app gives you access to the Microsoft cloud service for storing photos, documents, and other files in a cloud and access or share those files easier.
Store
Take advantage of the Windows Store and install one or more of the thousands of available apps designed for Windows 8. The Store is found in the Start screen, or use Search to search the Store app for any apps that you are trying to find.

What is meshing?

Meshing generically describes how devices are connected together. It is also the part of topology. There are two types of meshed topologies: partial and full.
In a partially meshed environment , every device is not connected to every other device.
In a fully meshed environment, every device is connected to every other device.
Wireless is the good example of meshing. Wan ( internet is also a good example of meshing where a computer have connectivity with all internet network.)

Describe Various Network Type

Local Area Networks Local area networks (LANs) are used to connect networking devices that are in a very close geographic area, such as a floor of a building, a building itself, or a campus environment.
Wide Area Networks Wide area networks (WANs) are used to connect LANs together. Typically, WANs are used when the LANs that must be connected are separated by a large distance.
Metropolitan Area Networks A metropolitan area network (MAN) is a hybrid between a LAN and a WAN.
Content Networks Content networks (CNs) were developed to ease users’ access to Internet resources. Companies deploy basically two types of CNs:
1.Caching downloaded Internet information
2.Distributing Internet traffic loads across multiple servers
Storage Area Networks Storage area networks (SANs) provide a high-speed infrastructure to move data between storage devices and file servers.
Advantage
Performance is fast.
Availability is high because of the redundancy features available.
Distances can span up to 10 kilometers.
Management is easy because of the centralization of data resources.
Overhead is low (uses a thin protocol).
Disadvantage of SANs is their cost.
Intranet An intranet is basically a network that is local to a company. In other words, users from within this company can find all of their resources without having to go outside of the company. An intranet can include LANs, private WANs and MANs,
Extranet An extranet is an extended intranet, where certain internal services are made available to known external users or external business partners at remote locations.
Internet An internet is used when unknown external users need to access internal resources in your network. In other words, your company might have a web site that sells various products, and you want any external user to be able to access this service.
VPN A virtual private network (VPN) is a special type of secured network. A VPN is used to provide a secure connection across a public network, such as an internet. Extranets typically use a VPN to provide a secure connection between a company and its known external users or offices. Authentication is provided to validate the identities of the two peers. Confidentiality provides encryption of the data to keep it private from prying eyes. Integrity is used to ensure that the data sent between the two devices or sites has not been tampered with.

What is virtual path?

Along any transmission path from a given source to a given destination, a group of virtual circuits can be grouped together into what is called path.

What is logical link control?

One of two sublayers of the data link layer of OSI reference model, as defined by the IEEE 802 standard. This sublayer is responsible for maintaining the link between computers when they are sending data across the physical network connection.

Why should you care about the OSI Reference Model?

It provides a framework for discussing network operations and design.

What is the difference between routable and non- routable protocols?

Routable protocols can work with a router and can be used to build large networks. Non-Routable protocols are designed to work on small, local networks and cannot be used with a router

In a Ethernet network, between any two points on the network, there can be no more than five network segments or four repeaters, and of those five segments only three of segments can be populated.

What is the difference between TFTP and FTP application layer protocols?

The Trivial File Transfer Protocol (TFTP) allows a local host to obtain files from a remote host but does not provide reliability or security. It uses the fundamental packet delivery services offered by UDP.
The File Transfer Protocol (FTP) is the standard mechanism provided by TCP / IP for copying a file from one host to another. It uses the services offered by TCP and so is reliable and secure. It establishes two connections (virtual circuits) between the hosts, one for data transfer and another for control information.

What is the minimum and maximum length of the header in the TCP segment and IP datagram?

The header should have a minimum length of 20 bytes and can have a maximum length of 60 bytes.

What is difference between ARP and RARP?

The address resolution protocol (ARP) is used to associate the 32 bit IP address with the 48 bit physical address, used by a host or a router to find the physical address of another host on its network by sending a ARP query packet that includes the IP address of the receiver.
The reverse address resolution protocol (RARP) allows a host to discover its Internet address when it knows only its physical address.

What is ICMP?

ICMP is Internet Control Message Protocol, a network layer protocol of the TCP/IP suite used by hosts and gateways to send notification of datagram problems back to the sender. It uses the echo test / reply to test whether a destination is reachable and responding. It also handles both control and error messages.

What is Bandwidth?

Every line has an upper limit and a lower limit on the frequency of signals it can carry. This limited range is called the bandwidth.

Difference between bit rate and baud rate.

Bit rate is the number of bits transmitted during one second whereas baud rate refers to the number of signal units per second that are required to represent those bits.
Baud rate = bit rate / N
Where N is no-of-bits represented by each signal shift.

What is MAC address ?

The address for a device as it is identified at the Media Access Control (MAC) layer in the network architecture. MAC address is usually stored in ROM on the network adapter card and is unique.

NETBEUI is NetBIOS extended user interface. A transport protocol designed by Microsoft and IBM for the use on small subnets.

What is redirector?

Redirector is software that intercepts file or prints I/O requests and translates them into network requests. This comes under presentation layer.

What is Beaconing?

The process that allows a network to self-repair networks problems. The stations on the network notify the other stations on the ring when they are not receiving the transmissions. Beaconing is used in Token ring and FDDI networks.

What is terminal emulation, in which layer it comes?

Telnet is also called as terminal emulation. It belongs to application layer.

What is frame relay, in which layer it comes?

Frame relay is a packet switching technology. It will operate in the data link layer.

What do you meant by "triple X" in Networks?

The function of PAD (Packet Assembler Disassembler) is described in a document known as X.3. The standard protocol has been defined between the terminal and the PAD, called X.28; another standard protocol exists between hte PAD and the network, called X.29. Together, these three recommendations are often called "triple X".

What is SAP?

Series of interface points that allow other computers to communicate with the other layers of network protocol stack.

What is subnet?

A generic term for section of a large networks usually separated by a bridge or router.

What is subnet mask?

It is a term that makes distinguish between network address and host address in IP address. Subnet mask value 0 defines host partition in IP address and value 1 – 255 defines Network address.

BOOTP helps a diskless workstation boot. How does it get a message to the network looking for its IP address and the location of its operating system boot files?

BOOTP sends a UDP message with a subnet work broadcast address and waits for a reply from a server that gives it the IP address. The same message might contain the name of the machine that has the boot files on it. If the boot image location is not specified, the workstation sends another UDP message to query the server.

What is a DNS resource record?

resource record is an entry in a name server's database. There are several types of resource records used, including name-to-address resolution information. Resource records are maintained as ASCII files.

What protocol is used by DNS name servers?

DNS uses UDP for communication between servers. It is a better choice than TCP because of the improved speed a connectionless protocol offers. Of course, transmission reliability suffers with UDP.

What is the difference between interior and exterior neighbor gateways?

Interior gateways connect LANs of one organization, whereas exterior gateways connect the organization to the outside world.

What is the HELLO protocol used for?

The HELLO protocol uses time instead of distance to determine optimal routing. It is an alternative to the Routing Information Protocol.

What are the three type of routing tables and What are the advantages and disadvantages of these?

The three types of routing tables are fixed, dynamic, and fixed central.
A fixed table must be manually modified every time there is a change.
A dynamic table changes its information based on network traffic, reducing the amount of manual maintenance.
A fixed central table lets a manager modify only one table, which is then read by other devices. The fixed central table reduces the need to update each machine's table, as with the fixed table. Usually a dynamic table causes the fewest problems for a network administrator, although the table's contents can change without the administrator being aware of the change.

What is Gateway-to-Gateway protocol?

It is a protocol formerly used to exchange routing information between Internet core routers.

What is BGP (Border Gateway Protocol)?

It is a protocol used to advertise the set of networks that can be reached with in an autonomous system. BGP enables this information to be shared with the autonomous system. This is newer than EGP (Exterior Gateway Protocol).

What is autonomous system?

It is a collection of routers under the control of a single administrative authority and that uses a common Interior Gateway Protocol.

What is region?

When hierarchical routing is used, the routers are divided into what we call regions, with each router knowing all the details about how to route packets to destinations within its own region, but knowing nothing about the internal structure of other regions.

What is multicast routing?

Sending a message to a group is called multicasting, and its routing algorithm is called multicast routing.

What is traffic shaping?

One of the main causes of congestion is that traffic is often busy. If hosts could be made to transmit at a uniform rate, congestion would be less common. Another open loop method to help manage congestion is forcing the packet to be transmitted at a more predictable rate. This is called traffic shaping.

What is packet filter?

Packet filter is a standard router equipped with some extra functionality. The extra functionality allows every incoming or outgoing packet to be inspected. Packets meeting some criterion are forwarded normally. Those that fail the test are dropped.

What are the difference between hub and switch?

Hub is a layer 1 device. It will out the signal from all of its port except the one from where its insert. It is unable to detect the collision. It works on single collision and single broadcast domain.
Switch is layer 2 device. It maintains a CAM table that store the MAC address of devices attached on its port. CAM table is used to make the forwarding decision. It works on per port collision and single broadcast domain.

What is layer?

How To Transfer Contacts From iPhone To Android (5 Ways)

As the HTC One M8 and the Galaxy S5 hit the market, some of you may see a good opportunity to switch from iOS to Android. Interestingly, when we talk to prospect switchers, the question that we get the most is how to go from  iPhone to Android without losing the iPhone’s contacts? Fortunately, we have some step-by-step solutions for you.
Despite the fact that these two mobile operating systems are two different worlds, there are multiple ways to transfer your data from one device to another. And trust me, it is a piece of cake. In most methods you will meet VFC. VFC or vCards is a file format standard for electronic business cards. vCards are often attached to e-mails and  instant messaging apps. They can contain pretty much anything, including names, addresses and phone numbers.

Method 1 – Manually (for small lists)

In case you want to move specific contacts only, you can use the Share Contact option. Open up the contacts up and select the contact you wish to save. Swipe down and select the tab, which allows you to either share it via e-mail or text.
If the number of contacts you want exceed ten, then this obviously is not your place to go. But if it is below that number, there is no need for using the methods below.

Method 2 – iCloud

The second way to accomplish transferring your contacts from your iPhone to your Android device is by simply using Apple’s cloud system.
1.    Head up to iCloud.com via your computer.
2.    Select the contacts that you want to export
1.    either one by one
2.    or click on the gear and use Select All
3.    Click the gear again and select Export vCard. Your computer will download a VCF file containing the selected contacts. The name of the file will be explicit as for how many contacts were exported
4.    Plug your Android phone to the computer, copy the VCF file to the local storage and import the contacts from the Contacts or People app.
Both Contacts and People applications feature an option that allows you to add contacts from various sources. Since you saved it to your SD card, you will select the Import from storage source.

Method 3 – via an App

Quoting the iPhone 3G commercial back in 2009; “there is an app for that”. We found two apps that might be useful for this procedure. And no, your computer does not need to be consulted. In this example, we will use the My Contacts Backup app, but there are other options out there.
1.    Download and launch the app on your iPhone.
2.    When the app (“MCBackup”) asks to access your contacts, tap OK
3.    Tap Backup
4.    Tap email, attach the VCF file to an email and send it to your Gmail account.
5.    Open up the email from your Android device, download the VCF file and import your contacts to the phone.
As demonstrated by the image below, the VCF file allows you to either select specific contacts to import to your list, or add the entire address book with the Add All X Contacts tab.

Method 4 – Import into GMail

In case your world revolves around Google’s ecosystem, there actually is a way to transfer your contacts via GMail. It’s pretty simple. Following method #2:
1.    Head up to iCloud.com via your computer.
2.    Select the contacts you want to save.
3.    If you want to save the entire list, click the little gear button at the lower left and Select All.
4.    Click the gear icon and select Export vCard (see method #2).
5.    Your computer will download a VCF file containing the exported contacts.
Then
1.    Log in to your Google account.
2.    Click on the Gmail logo, located at the top left corner of your dashboard.
3.    Select contacts
4.    Click the “More” dropdown menu in Contacts, and select Import.
5.    Click Import again. The contacts will be automatically synced to your Android device(s), connected to this account.

Method 5 – Export contacts to GMail with iTunes

If your iPhone is running iOS 4.x and lower, then the rest methods are practically redundant, since apps are not compatible with that version of iOS and iCloud did not exist back then. I know, iTunes can cause frustration sometimes, but it’s the only way out in some occasions. It is as easy as the other methods, and it definitely gets the job done.
1.    Download and launch iTunes.
2.    Connect your iPhone to the computer.
3.    Open the handset’s device summary page.
4.    Click the Info tab.
5.    Check “Sync Contacts With” and then select “Google Contacts”.
6.    Type your Google account’s username and password.
7.    Click Apply.
8.    Make sure your Android device is connected to the particular GMail account.
9.    Allow Google to sync your contacts to your Android phone.
