The most common type of computer file storage is Hard Disk , it is in built with computer . External Storage is Like CD , DVD , Pen Drive , Floppy Drive .

It's important to back up your computer programs incase of something happening such as your computer crashing. Backing up your programs will ensure that any work you have on those programs will be saved.

Microsoft's website has a large compilation of guides and help menus for troubleshooting issues with various software and hardware of your computer. They also have a help center.

CUI stands for Character User Interface. it means that you have to type commands to interact with the computer. For example, in DOS for every thing we type the commands.

GUI stands for Graphical User Interface. It means that you do not need to type commands to interact with the computer; instead you have to click with the help of a mouse on the icons of ready made commands. An example is Windows.

Yes, cell phones are input-output devices.The 'input' part is you pressing keys to dial a number. The 'output' is the display screen.

Go to System Preferences, then Displays, then the resolutions are listed on the right. The highlighted choice is the resolution of your monitor. To choose a different one, just click on a different resolution.

Command prompt/line is used to execute entered commands. Command prompt is mostly commonly used to execute batch files, perform advanced administrative functions, and troubleshoot and solve certain kinds of windows issues.

Electronic communication is the use of electronic devices or electronic waves such as cellphones, email, talkie-walkies, sending and receiving radios etc.

VPN technologies are a good choice for connecting home offices, mobile users, and other offices back to your office though the use of the internet. There are also clientless VPN options which allow users to connect to the office through a secured webpage.

A Backup

The technical name is cloning.

All programs and data are executed from memory (RAM)

but it first needs to be fetched from wherever it is stored.If there is insufficient free memory, then some memory must be freed up by writing t to disk in the paging file. You can minimize the chances of this happening by maximizing the amount of memory in the PC.

.

The second impact is memory speed, especially the speed at which data can be transferred between RAM and the CPU. Data is actually transferred to cache memory on the CPU chip from main memory before it is executed,and then results are written back to main memory. The speed of this data transfer is affected by the design of the system, and the speed and quality of RAM installed, and by the setup of RAM timing in BIOS.

You can purchase a mobile computer workstation from retailers such as Amazon. Once on the website, type "Mobile computer workstation" into the search field at the top of the page and press enter to bring up the item.

The start menu is a very useful interface because it meens all the things you can do on the computer don't have to clog up your desktop.

Yes. Suppose the program name is foo. You do not need two copies of foo.exe, just two data directories. I will call them jack and jill.

1. If the directory for saved data is configurable through an environment variable, using foodir as an example, or on the command line, create two .bat files and a shortcut to run each.

foo-jack.bat

foodir=c:\jack

foo

foo-jill.bat

foodir=c:\jill

foo

2. If the directory is not configurable, the program might be using the current directory. Make sure the directory containing foo.exe is in the PATH and create two .bat files like this:

foo-jack.bat

cd \jack

foo

foo-jill.bat

cd \jill

foo

It is estimated that 1.4 - 2 billion computers exist worldwide.

You can get a lock with figerprint recognition software,that will only allow you to use your computer.

In simple terms a single processor can only process one machine instruction at a time; it's just not possible to execute two or more instructions simultaneously and therefore not possible to execute 2 programs simultaneously.

However, it's not quite as simple as that because a modern processor can have 2 or more cores, in which case it is possible to execute 2 or more instructions simultaneously. However, that's not quite the same thing as executing 2 programs simultaneously as we invariably execute far more threads of execution than we have cores available.

Note that a program consists of one or more processes and a process consists of one or more threads of execution. Although it is theoretically possible to execute two threads simultaneously upon two cores, when those cores share the same processor they also share the same L2 cache and that's really only beneficial when both threads share the same process. With 2 independent processors there's a better chance of simultaneous program execution, however it's nigh on impossible to guarantee this unless the system is specifically designed for that purpose. In a multi-processing, multi-threaded environment, task-switching makes it next to impossible for any two independent programs to execute simultaneously because every thread has to yield to waiting threads.

You need computer skills for a wide range of purposes, especially in today's modern world. Authors now type on computers. Artists draw on them. Bankers store important information on them. Even for something as simple as posting an ad for a gardening service could require computer skills.
