Keyboard shortcut

Have you ever been in a situation where one of your hardware components malfunction or is not working at all? These components I am talking about can be a mouse or keyboard. I reckon that about seventy percent of people can work on computers on User levels but only twenty percent can keep on working if any of these components is not working. When the keyboard is not working you can keep on working with your computer by using onscreen keyboard. Again if mouse is malfunctioning you can use keyboards shortcut instead of a mouse.

Below are examples of these shortcuts 

Keyboard shortcut                     Description
CTRL+ S                                       : Save
CTRL+P                                        : Print
CTRL+Y                                        : For Redo
CTRL+Z                                        : For Undo
CTRL+F                                        : Find command
CTRL+G                                        : Find and replace dialog box
CTRL+HOME                               :Top of the document
CTRL+END                                   : Down the document
CTRL+C                                        : Copy
CTRL+A                                        : Select all
F1                                                   : Help
ARROWS                                      : Control the cursor


These were some of the examples of keyboard shortcuts but the list is endless. Notice that most of the shortcut use control key (CTRL).

Network Setup

Initially network was ideal for for corporates though there are still business that has not yet implemented network  due to some reasons or maybe not understanding it importance. In nowadays you find homes where TV, sound system, nodes and telephones are connected and controlled in a single location. This is an examples of a network though some people only associate network with nodes(computers) , in fact network is formed when two devices are connected together to share resources. Two cellular phones connected via wireless personal area network (Bluetoooth) forms a network. Network range form local area network (LAN), metropolitan area network( MAN) and wide area network(WAN). The main benefits of network are central data management, resource sharing and lastly but not list security.

Thing that one need to consider want to setup a local area network (LAN)

Transmission media
This can be cables you use to connect your network component and these component can be computers, printer and scanner.

Media connector
Media connect can be a device that you use to connect to cables, for example BNC  and RJ45

Network Interface Cards(NIC)
Luckily all computers to come with NIC embeded within them already and this device allow computers in a network to communicate with one another

Protocols and Software
Most widely used protocol is TCP/IP

Depending to the size of your network you might also needs more hardware devices such as Hubs, Bridge and Router. With all the above requirements you can successfully start your own network.

Computer backups and bottlenecks

It is unfortunate that when you buy a computer you don't get a manual of to manage it in some stores. I can not blame them because I think they reckon you can not buy something you can not use, yet in fact we normally do. Just imagine you are the CEO  and you suppose to do the report to the board of the company about the progress in terms of finances and productivity of the company. You neatly compile your report presentation in your PC making sure everything is there, then you wait for the big day.Sadly just before the presentation your OS crashes and all the work was in there. That where the backup come on board because if you were taking backup of your operating system and files you now can relax and recover your file from where you took the backup of your files. I think it is now clear how important it is to take the backups of your files regularly.

You need to learn more on features of your computer and use Internet if required. Make use of search engines like Google, many Programmers and Researchers use search engines to find solutions to some problems. Some of the computer bottlenecks are some of the things that people can solve themselves but end up paying because of ignorance.
