Computer games

1) Computer game is a game that is either played on PC or laptop. There are many different games and with graphics whereas the quality of the computer also effects the graphics of the games. Moreover, many people use it as a source of entertainment and stress relief and educational purposes. Furthermore, games are controlling objects which can be also be played with controller. 

2)  A good game is which includes good graphics, has high speed gaming , good sound quality. Moreover, if a  person want to buy a good game one should really look for views and comments. Good games should be hard to solve and takes time to understand. Moreover, a good game should be challenging.


3) 3. A bad game can be the one which is shorter than it is needed to be. Moreover, some games have slow processing can can be counted as a bad game. A bad game can also be easier to play not like that much challenging that people expect. furthermore, a bad game also includes, low graphic quality, sound quality which also affects one's vision.

	Peer-to-Peer	Client/Server
How does it work? Give an example	Peer-to-peer network operating systems allow users to share resources and files located on their computers and to access shared resources found on other computers. However, they do not have a file server or a centralized management source. In a peer-to-peer network, all computers are considered equal; they all have the same abilities to use the resources available on the network. Peer-to peer networks are designed primarily for small to medium local area networks. AppleShare and Windows for Workgroups are examples of programs that can function as peer-to-peer network operating systems.	Client/server network operating systems allow the network to centralize functions and applications in one or more dedicated file servers. The file servers become the heart of the system, providing access to resources and providing security. Individual workstations (clients) have access to the resources available on the file servers. The network operating system provides the mechanism to integrate all the components of the network and allow multiple users to simultaneously share the same resources irrespective of physical location. Novell Netware and Windows 2000 Server are examples of client/server network operating systems.
Advantages	- Less initial expense - No need for a dedicated server. - Setup - An operating system (such as Windows XP) already in place may only need to be reconfigured for peer-to-peer operations.	- Centralized - Resources and data security are controlled through the server. -  Scalability - Any or all elements can be replaced individually as needs increase. - Flexibility - New technology can be easily integrated into system. - Interoperability - All components (client/network/server) work together. - Accessibility - Server can be accessed remotely and across multiple platforms.
Disadvantages	- Decentralized - No central repository for files and applications. - Security - Does not provide the security available on a client/server network.	- Expense - Requires initial investment in dedicated server. - Maintenance - Large networks will require a staff to ensure efficient operation. - Dependence - When server goes down, operations will cease across the network.

3.3 Inside Computers

1)  There are 2 RAM chips. Both the chips were together and were located on the motherboard. We come to know the quantity of RAM by reading a white sticker pasted on the RAM chip. Both the chips have 120MB of RAM individually. These can be removed by clicking the two white switches (Top and bottom) in the direction opposite to the original one and then pull the chip. Yes, we were comfortable doing this with our own computer.

2. The Hard Drive is located on extreme right on the upper corner of the tower. It is      

Connected to the motherboard with two wires called IDE Cable and SATA Cable. the amount of hard drive in written on the hard drive and there was 148 Gb of hard drive.

3) It is located at the top left corner of the tower. It uses 94 watts. I think the advantages of low watt power and high watt power supply is:

   Low watt power supply                                                         High Watt power supply

 1) Usage of less power of the computer                               1) High speed computer                      

       2) Less energy wasting by the computer                              2) Less time for starting

4. It's located on the motherboard. The CPU is located under the heat sink fan. It’s not that hard to access you just need to know how to put it back safely and carefully on its right place. I think it is set up this way so that the fan in front of this takes all the hot air the CPU leaves.

5) The optical drive is on the front of the tower. Its CD Drive and DVD drive. I know this because computer doesn’t work with Blu-ray CDs or DVDs.

6) There is only one fan on the top OF CPU. I think reasons that we would not need more fans because CPU is the major part of the computer that needs to cool down because that where everything is coming. If the computer is working like whole 24 hours the fan helps the CPU to cools down so that it can work infinitely. Sometimes you may have noticed that CPU makes some noise like air coming out of it that’s where you your CPU need to cool down and the fan helps it to work again.

7)  Yes, there is video card in the computer and it is a dedicated video card. It is a graphic card that is used for gaming in the computer. This video card provides good graphics for the game so that people can have fun playing it.

8) Yes, there is a sound card. I know because it is located on the motherboard. Moreover, in the front of the CPU if you really like to hear the music with headphones they have space for wires to get into the tower or the Computer.

9) The three possible hardware upgrades for this computer are a webcam, a printer and speakers

10)  Three advantages of upgrading an old computer rather than buying a new one:

        - No wastage of money

        - You can assemble a new window in an old computer and gain some Knowledge    

           about how to do it.
        - you save time

The one disadvantage is the old one can cause problems because it’s still got an old CPU.  Moreover, some new Hardware’s or software’s will not work on old computers. Furthermore the computer will work slow.

3.2 Building or Buying

3 advantages of building a PC 

     -  Most Parts Come With a 1-Year Warranty

     - Low Cost

     - You Will Learn so Much and building a computer is a great skill

3 advantages of buying a PC 

     - Technical Support

     -  Less knowlege required

      - Already made for you you don`t have to waste extra time to make some parts. 

i would go with building a PC rather than buying it because Most computer systems come pre-built with the specifications and components already selected for you. This often can lead the user to have to sacrifice certain features that they may not want to give up. By building a computer from components, the user is able to choose the parts that best match the computer system they desire. 

Moreover, you gain some knowledge about computers by actually looking at the parts  and knowing where to put them. This way you working more like an Engineer by using your critical thinking.
