MS Word and PowerPoint

Hi everybody, in this post I would like to write about my study on week 6.

Week 6 was more interesting than others I think. Because it was more practical, full of fun in the class and so on. This week we have studied about Microsoft Office Application Software. Mr. Azam our lecturer has taught us how to use Microsoft Word 2010. This Software is more convenient than others as it has a lot of new features. We have learnt from how to start-up that software. To start up Microsoft Word 2010 we have to click on the button windows and write there Word I think the shortest way, of course our lecturer taught us how to start it formally like entering Microsoft applications and so on, but to tell the truth we all students knew so we got it boring at first. Because Lecturer was teaching from small things such as choosing fonts , making tables and so but after while we got deeper and he taught us how to work with pictures, make flyers, edit and so it was more than just interesting, it was useful and what we always need in our daily life of XXI century. And the most interesting came when the second came, lecturer turn by turn called us to do a practise for example make something in front of everybody, it was so embarrassing when me and my classmate Timurmalik couldn't merge the cells of the table :D. In the next class we have studied a little bit about the PowerPoint application it wasn't very interesting because we have studied about only common things. The next day we had Mid-session exam from this subject the test wasn't difficult but I didn't do my best I mean I couldn't as I haven't prepared well and there were 5 open questions which made me crazy........ But anyway I could at least answer to them. In the class of Friday we had another assignment to do, the task which we required to do was to make a flyer about any sport club of AiU (the university which I'm studying). I think nobody found that task difficult because the instructions were clear and understandable so we did it easily, That's what I have studied on week 6  and I think I haven't made anybody get bored with my story of this week. I have learnt a lot of new things which will be very, very useful in my life. we always need to work on software which we have studied this week so I think this week I did all my best to learn all things from my lecturer.

Windows 7

Hi everyone.. In this week we mostly studied about "Microsoft Windows 7".

• Microsoft created the operating system, Windows, in the mid-1980s
• They have a version of the operating system that is designed for the home user, and a professional version, which is intended for businesses.

•  The versions differ in the depth of networking, security, and multimedia support.
• Windows is proprietary software, which means that Microsoft has placed restrictions on how people can use or copy the software. 

 Nowadays windows is one of the best software for PC's, laptops and to some phones. It is very popular among all Computer users of the world. And nowadays most people still use windows 7. Windows 7 also saves time by not booting up various devices during Start Up unless they are currently being used. In other words, if you are not using a Bluetooth device at the moment then Windows 7 will not waste time by running that program in the background. It will wait until you have plugged it in. It is the follow-up to the Windows Vista Operating System which was released in 2006. An operating system allows your computer to manage software and perform essential tasks. It is also a Graphical User Interface (GUI) that allows you to visually interact with your computer’s functions in a logical, fun and easy way. For example, in Windows 7 you can view two windows side by side by using the Aero Snap feature. This feature automatically sizes or snaps two windows to fit together on the screen thus allowing you the convenience of viewing them next to each other.The Windows 7 environment is not an extension of XP; it is an entirely new interface. Although the underlying file structure is the same, there is less to file management compare to XP. Windows 7 does not require the knowledge of storing and accessing files as in XP and earlier versions — the file hierarchy is behind the scenes. Windows 7 is in fact easier to use, but you need to be acquainted with it. 

 The windows 7 has many useful things rather than other windows for example searching more convenient and it has more interesting toolbars and so on. And  it has function Special folder On Microsoft Windows operating systems, Special Folders are folders which are presented to the user through an interface as an abstract concept, instead of an absolute folder path. This makes it possible for an application to ask the operating system where an appropriate location for certain kinds of files can be found, regardless of what version or language of operating system is being used. 

Windows 7 has very useful function called  Windows 7 Advanced Disk Defragmentation Windows 7 lets you perform the defragmentation operation from the command line as well. This called Advanced Windows 7 Disk Defragmentation and it was not available in the older versions of Windows. The command line disk defragmentation is performed with the help of the defrag command.

Network

This week of study has been very interesting. In this week we mostly studied about network and communication. In class we have studied about many things.

Computer Network

It is simply a group of interconnected computers.

Two or more computers are connected via hardware or software, and able to communicate with each other.

Example of a computer network:

the Internet, ATM, school network, e-banking, home network, etc

And our lecturer gave us some explanation about why to use networks. We use network to share recourse , information and collaboration and promote communication. And there are 5 major network components:

1.Communication Media

2.Interconnecting Devices

3.Computers

4.Networking Software

5.Applications

We have learnt about signals too, there 2 types of signals Analog signal and Digital signal

• Digital signal – carries discrete data between computer devices. The signals represent a pattern of bits.
• Analog signal – also known as radio signal. It is the signals transmitted along conventional telephone lines.
    
  In another lecture we continued studying about network. Mostly we studied about communication channel, wireless media and medium, physical media and medium and digital communication.

Communication Channel

Some type of link through which the data can be transmitted or transferred from one computer to another.

To send data through the channel requires some type of transmission media, which may be either physical or wireless.

Wireless Media

Also known as unguided medium.

Microwave system – transmits data via high-frequency radio signals through the atmosphere

Satellite system – receive transmitted signals, amplify them, and then transmit the signals to the appropriate locations

Cellular technology – uses antennae resembling telephone towers to pick up radio signals within a specific area (cell)

Infrared technology – transmits data as infrared light waves from one device to another, providing wireless links between PCs and peripherals

Physical Media

Twisted-pair cable – consists of two independently insulated wires twisted around each other (least expensive type of cable—the kind that is used in many telephone systems)

Coaxial cable – consists of an insulated center wire grounded by a shield of braided wire (the primary type of cabling used by the cable television industry;  it is more expensive than twisted pair)

Fiber-optic cable – contains hundreds of clear fiberglass or plastic fibers (threads) (made from thin, flexible glass tubing; bandwidth is greater, so it can carry more data; it is lighter than metal wires and is less susceptible to interference; it is fragile and expensive)

ISDN line – a special digital telephone line that transmits and receives information at very high speeds

  

Digital Communication

Communication has changed radically in today’s digital age and our lifestyle.

Today, we are talking about digital communication, digital entertainment, digital mobility and so forth.

It’s already happening accessing home computer from our cell phone. This is the era of digital telephony.

In the next class we mostly studied about peer to peer network.

Peer-to-Peer Networking

Peers with no centralized control over shared resources

Can share resources with any other computer on network

No computer has higher access priority

No computer has more responsibility to provide or shared resources

 In a peer-to-peer network, all computers are considered equal. Each computer controls its own information and is capable of functioning as either a client or a server depending upon the requirement. Peer-to-peer networks are inexpensive and easy to install. They are popular as home networks and for use in small companies. And  we studied a bit about server networks and I think this week's learning was very interesting and full of new information, I've learnt many useful things and I think those will be useful in my future life and career.
