In what format is data stored in a computer?
Data is store momentarily in computers in RAM. Random Access Memory are chips that contain registers that retain their electrical state for as long as its either changed or the power is turn off. Data can also be store permanently in a Hard Drive. HD are nothing more than a magnetic disc that spins around while a writing head magnetises the surface of the disc, creating areas to simbolize ones and zeros; the digital language of computers.
What Part of a computer that plays music and data?
A computer can only produce sound if it contains the right hardware. These come in the forms of sound cards or sound chips. In most cases these devices only convert the sound data from digital to analogue signals - the computer itself reads the binary data and decodes it into a form understandable by humans.
Data validation best refers to?
Data Validation is a process that ensures that data entered into the database form, a web form, or a computer program conforms to the correct data type.
What is a group of computers is called?
A group of computers might form a network, but this is not necessarily the case. There is no commonly used collective noun for computers.
What is a serial connector?
Serial connector term is used for an interface connector on which the protocol of data transfer is serial type. Serial data transfer means one electrical connection or signal for data transfer (one bit at a time from transmitter to receiver) at specific speed (bits per second). Note that on the connector actually there may be more than one electrical connections for signals other than serial data, which include clock and power in some cases, or control signals. Serial data itself may be electrically sent in differential form in which case serial data itself needs two wires (positive and negative). Common examples of serial connectors include serial port (RS232) and USB.
What data does the computer record?
Computers record data in the form of "bits", Binary Digits.
Distinguish between analog computer and hybrid computer?
ANALOGUE COMPUTERS ARE THE COMPUTERS WHICH PROCESS DATA IN A WAVE FORM WHILE HYBRID COMPUTERS POSSESS DATA IN BOTH DISCREET AND WAVE FORMS.
Write a sentence about data at least 8 words?
Data is a form of stored knowledge by computers and other forms of technology.
What is data transmission channel?
Transmission channels are defined as paths through which electrical signals can pass through. It may be in form of a physical cable.
Physical layer in OSI model?
The physical layer is layer 1. It comprises the hardware (routers, repeaters, hubs, switches, etc.) that are used to form the physical basis of a network. They receive, process, and transmit raw electric (or optical) signals, rather than logical data packets.
What does a data refer to?
Data refers to information, facts, or statistics that are collected, stored, and analyzed for various purposes. Data can be in the form of text, numbers, images, videos, or any other type of information that can be processed by computers.
What signals does Ions charged particles form?
light signals
Does Ethernet transmit signals in digital form or analog form?
HDMI is a digital replacement for existing analog video standards, such as 3D, an Ethernet data connection and improved audio and video capacity.
What is plural for computers?
The noun computer is the singular form; the plural form is computers.
What is the function of the digitizing tablet?
A digitizer is a device that converts analog signals into digital form. The most common form of a digitizer today would be a data converter.
What is difference between encoding and modulation?
encoding means to encode the data generally it uses for security purposes, we encode the data by using some mathematics operations so that no other could get the information. in modulation we also change the input but it is used for the send the signals to a long way. the week frequency signals can not travel to the long way so we superimpose the week frequency signals to the high frequency signals so that it could reach at it destination. the reverse process of encoding is decoding and the reverse process of modulation is demodulation so that we can get our data in a original form.
What is data.?
Data are the raw facts or figures which are processed to get the information.
