This message means someone tried to start the computer with the case open, AND that the BIOS is set to halt if the chassis intrustion switch indicates that the case is open.
The arrangement of the computers in a network is called the?
Without knowing a bit more about the context, probably "topology".
Common network topologies are ring, star, bus and mesh.
The type of input that is a set of instructions that direct the computer?
No - an input device is a device that provides data input to a computer. A keyboard, mouse, microphone, and Web cam are examples of input devices. A monitor and speakers are examples of output devices.
A set of detailed instructions given to a computer is called a program.
Does having two network cards increase internet speed?
Simply having two network cards does not increase you internet speed.
If those cards are connected to the Internet, they can increase your speed, your total speed being, in theory, the sum of the speeds of the connections attached to each of your two network cards. This setup however is problematic for home users, as requires a mechanism to balance the load on the two cards, can pose problems if you get to have multiple IP addresses etc.
Most likely, your answer is "no". However, if you wish to connect to multiple ISP's and increase your network throughput that way, look into "load balancing" and "multi homing".
Can tracking cookies harm your computer?
Tracking Cookies are cookies that track your browsing behaviors or surfing habits. Marketers use this data to understand how users use their partner websites and optimize their networks for the average user that visits their networks which helps generate a bunch of marketing statistic.
In fact, cookie is a plain txt file that sits on your computer in a temporary folder that stores data about a browsing session. If you log into a website it generally sets a cookie to temporarily store your information so you don't have to log in every time you change a page.Tracking cookies don't infect your computer on their own out of nowhere. They are stored on a computer once a website that uses tracking cookies is visited. In next time spyware doctor detects tracking cookies, take a look at the names and don't visit that website anymore. Cookies do not usually pose a threat, anti-virus and anti-spyware programs tell you they do but they are not usually anything to worry about.
Is a graphics pad an input or output?
It is an input because it is giving the computer information. Things like printers are an output because they are taking information out of the computer and giving the info or data to the user. Keyboards, mice, scanners are all input devices. Things like speakers, and headphones are output.
Why is your new laptop running slow?
The Dell Inspiron Mini was not intended to be lightning fast. It is a netbook, and netbooks (unless you spend the extra money) usually only come with 1 gig of RAM with most, only being upgradeable to 2 gigs of RAM. You can purchase a variety of netbooks now with 2 gigs of ram, upgradeable to 4 gigs, which in my opinion, isn't too bad for basic everyday use, however, a netbook was never designed, nor intended for intense usage.
What computer application can take numbers and electronically calculate data?
Calculator lol pretty high tech stuff
How many software in computer?
This is such an open ended question that any number of answers may prevail. I suggest the following:
Operating Systems (OS)
Hardware Drivers
Application Software
Games
Media Players
Connectivity Software
Software can also be categorized according to the following:
Retail software: This type of software is sold off the shelves of retail stores. It includes expensive packaging designed to catch the eye of shoppers and, as such, is generally more expensive. An advantage of retail software is that it comes with printed manuals and installation instructions, missing in hard-copy form from virtually every other category of software. However, when hard-copy manuals and instructions are not required, a downloadable version off the Internet will be less expensive, if available.
OEM software: OEM stands for "Original Equipment Manufacturer" and refers to software sold in bulk to resellers, designed to be bundled with hardware. For example, Microsoft has contracts with various companies including Dell Computers, Toshiba, Gateway and others. Microsoft sells its operating systems as OEM software at a reduced price, minus retail packaging, manuals and installation instructions. Resellers install the operating system before systems are sold and the OEM CD is supplied to the buyer. The "manual" consists of the Help menu built into the software itself. OEM software is not legal to buy unbundled from its original hardware system.
Shareware: This software is downloadable from the Internet. Licenses differ, but commonly the user is allowed to try the program for free, for a period stipulated in the license, usually thirty days. At the end of the trial period, the software must be purchased or uninstalled. Some shareware incorporates an internal clock that disables the program after the trial period unless a serial number is supplied. Other shareware designs continue to work with "nag" screens, encouraging the user to purchase the program.
Crippleware: This software is similar to shareware except that key features will cease to work after the trial period has ended. For example, the "save" function, the print function, or some other vital feature necessary to use the program effectively may become unusable. This "cripples" the program. Other types of crippleware incorporate crippled functions throughout the trial period. A purchase is necessary to unlock the crippled features.
Demo software: Demo software is not intended to be a functioning program, though it may allow partial functioning. It is mainly designed to demonstrate what a purchased version is capable of doing, and often works more like an automated tutorial. If a person wants to use the program, they must buy a fully functioning version.
Adware: This is free software that is supported by advertisements built into the program itself. Some adware requires a live Internet feed and uses constant bandwidth to upload new advertisements. The user must view these ads in the interface of the program. Disabling the ads is against the license agreement. Ad ware is not particularly popular.
Spyware: Spyware software is normally free, but can be shareware. It clandestinely "phones home" and sends data back to the creator of the spyware, most often without the user's knowledge. For example, a multimedia player might profile what music and video files the software is called upon to play. This information can be stored with a unique identification tag associated with the specific program on a user's machine, mapping a one-to-one relationship. The concept of spyware is very unpopular, and many programs that use spyware protocols were forced to disclose this to users and offer a means to turn off reporting functions. Other spyware programs divulge the protocols in their licenses, and make acceptance of the spyware feature a condition of agreement for using the software.
Freeware: Freeware is also down loadable off the Internet and free of charge. Often freeware is only free for personal use, while commercial use requires a paid license. Freeware does not contain spyware or Ad ware If it is found to contain either of these, it is reclassified as such. Public domain software: This is free software, but unlike freeware, public domain software does not have a specific copyright owner or license restrictions. It is the only software that can be legally modified by the user for his or her own purposes. People are encouraged to read licenses carefully when installing software, as they vary widely.
there are many types of soft wares
How much time is appropriate for kids to spend on the computer?
about 1 hour but you should not spend too much time on the computer anyway
Name the part of the computer that stores all information and software?
The Hard Drive is the main storage unit in a normal, desktop computer. This is the only internal component in a standard computer that has information when the machine is turned off (all your saved files, the operating system (such as Windows), etc).
There are other components (such as RAM, or Random Access Memory) that store data, but this usually serves a special purpose, or is only at run-time.
Shop Around For The Best Cheap Laptop Deals?
When looking for the best cheap laptop, shop around to get the best deal. Many stores list one or two laptops at a great price each week to draw customers to the store. Compare the specifications for these laptops so you know how to spot a deal. Intel processors are more expensive than AMD processors. Consider buying a different processor to save money without sacrificing computing power.
What function does the CPU perform in a personal computer?
CPU stands for central processing unit. Overall a personal computer can be divided into the following major parts from point of view of functions performed:
1. Input devices (keyboard, mouse)
2. Output devices (monitor which displays the output or results of work being done on the computer)
3. CPU (central processing unit, which is the brain of the computer which does all the processing and calculations on data inputs and provides output on screen or printer)
4. Storage devices (memories, hard disk which store data).
Many times in common language the CPU term is used for the computer box unit which contains motherboard, processor, hard disk, CD/DVD and floppy drives. This is the box to which we connect monitor, keyboard, mouse and printer through cables. In technical terms the term CPU is used only for the processor, which fits on the motherboard.
Central Processing Unit (CPU), in computer science, microscopic circuitry that serves as the main information processor in a computer. A CPU is generally a single microprocessor made from a wafer of semiconducting material, usually silicon, with millions of electrical components on its surface. On a higher level, the CPU is actually a number of interconnected processing units that are each responsible for one aspect of the CPU's function. Standard CPUs contain processing units that interpret and implement software instructions, perform calculations and comparisons, make logical decisions (determining if a statement is true or false based on the rules of Boolean algebra), temporarily store information for use by another of the CPU's processing units, keep track of the current step in the execution of the program, and allow the CPU to communicate with the rest of the computer.
A CPU is similar to a calculator, only much more powerful. The main function of the CPU is to perform arithmetic and logical operations on data taken from memory or on information entered through some device, such as a keyboard, scanner, or joystick. The CPU is controlled by a list of software instructions, called a computer program. Software instructions entering the CPU originate in some form of memory storage device such as a hard disk, floppy disk, CD-ROM, or magnetic tape. These instructions then pass into the computer's main random access memory (RAM), where each instruction is given a unique address, or memory location. The CPU can access specific pieces of data in RAM by specifying the address of the data that it wants.
As a program is executed, data flow from RAM through an interface unit of wires called the bus, which connects the CPU to RAM. The data are then decoded by a processing unit called the instruction decoder that interprets and implements software instructions. From the instruction decoder the data pass to the arithmetic/logic unit (ALU), which performs calculations and comparisons. Data may be stored by the ALU in temporary memory locations called registers where it may be retrieved quickly. The ALU performs specific operations such as addition, multiplication, and conditional tests on the data in its registers, sending the resulting data back to RAM or storing it in another register for further use. During this process, a unit called the program counter keeps track of each successive instruction to make sure that the program instructions are followed by the CPU in the correct order.
How do you make conference call computer to computer?
There are many different methods, but Skype is definitely one of the easier ones. It's free to call other skype users, and you can have conference calls of up 5 people with the current version.
What The way in which you communicate with multiple users at the same time?
a group discussion in a chatroom
Do computers made by different manufacturer generally have the same or different instruction sets?
The machine code architecture of computers made by different manufacturers are different. This is why machine code from one platform cannot executed on a different platform because of instructional differences. Assembly programs made on one platform can also not be ported to a different platform.
How can you speed up your wireless internet?
there are ways to speed up your computer, just google "how to speed up your computer" or "how to speed up your internet" that's how I got my computer from sllllllllllllllllllooooooooooooooooooooowwwwwwww to, well at least tolerable.
Also make sure you got an antivirus program, I have AVG free edition and it works great. Also you can go on a windows XP or Vista computer (maybe higher versions too) click start> all programs> accessories> system tools> and use Disk Defragmenter or Disk Cleanup.
Well the driver will take up very little hard drive space depending on the video card. Now all video cards have built in memory (RAM) but after the ammount that is on the video card runs out. It will start using the RAM on your computer. Just depends on the game you are trying to run. Also your Proccessor, RAM and Video Card all work together for running games. Hope this helped :)
Which utility keeps track of where your documents spreadsheets and presentations reside?
File management is the utility that keeps track of where your documents, spreadsheets, and presentation are located. It also displays other files that are on your computer like pictures.
Is a drive a input or an output?
A drive, whether a hard disk disk, flash memory drive, or floppy disk drive is a peripheral device that can be used for both input and output. This is in contrast to certain devices that can be used for only for output like monitors (non touch screen) and devices which can only be used for input like keyboards.
What is a wordprocesser and its function?
A word processor is a computer application that helps with writing down words (usually into documents, letters or notes etc). Typically a word processor will help with:
1. Creating a new letter or document (potentially from a template).
2. Editing and changing a document (searching for text, changing text, moving text etc)
3. Viewing of documents, printing of documents and saving of documents for later retrieval.
What is a computer network located within a limited geographical area?
Typically that would be a LAN (local area network)
