What are two interpretations of the term random access memory?
What are two interpretations of the term random-access memory? It is memory that is volatile, and it can be data can be read from and written to it easily and rapidly.
What is bit nibble and byte?
Each 1 or 0 in a binary number is called a bit. From there, a group of 4 bits is called a nibble, and 8-bits makes a byte. Bytes are a pretty common buzzword when working in binary. Processors are all built to work with a set length of bits, which is usually this length is a multiple of a byte: 8, 16, 32, 64, etc.
What byte means?
In most computer systems, a byte is a unit of data that is eight binary digits long. A byte is the unit most computers use to represent a character such as a letter, number or typographic symbol.
What is the term for the transmission of messages and files via?
What is the term for the transmission of messages and files via a computer network? email.
How is data processed into information?
Data processing can be done manually using pen and paper. Mechanically using simple devices like typewriters or electronically using modern data processing tools such as computers. It refers to the sequence of activities involved in data transformation from its row form to information.
What is data output?
Data output is the process and method by which data can be studied under different circumstances and manipulated as required by the researcher. Any statistical analysis produces an output data that needs to be studied.
What is input and output devices?
An input device sends information to a computer system for processing, and an output device reproduces or displays the results of that processing. Input devices only allow for input of data to a computer and output devices only receive the output of data from another device.
What is and output device?
An output device is any piece of computer hardware equipment which converts information into a human-perceptible form or, historically, into a physical machine-readable form for use with other non-computerized equipment. It can be text, graphics, tactile, audio, or video.
What is a ROM and what does it do?
Read-only memory, or ROM, is a type of computer storage containing non-volatile, permanent data that, normally, can only be read, not written to. ROM contains the programming that allows a computer to start up or regenerate each time it is turned on.
What is the meaning of ROM?
Read-only memoryRead-only memory / Full name RAM, which stands for random access memory, and ROM, which stands for read-only memory, are both present in your computer. RAM is volatile memory that temporarily stores the files you are working on. ROM is non-volatile memory that permanently stores instructions for your computer.
How many bits are allocated for a character on computer keyboard?
To store character value, computer will allocate 1 byte (8 bit) memory. 65 will converted into binary form which is (1000001) 2. Because computer knows only binary number system.
What is meant by the binary number system and the Denary number system?
A Binary system has only two states, Logic “0” and Logic “1” giving a base of 2. A Decimal system uses 10 different digits, 0 to 9 giving it a base of 10.
What is a bit and byte?
Bits are usually assembled into a group of eight to form a byte. A byte contains enough information to store a single ASCII character, like "h". A kilobyte (KB) is 1,024 bytes, not one thousand bytes as might be expected, because computers use binary (base two) math, instead of a decimal (base ten) system.
What is the storage unit in a computer called?
byte, the basic unit of information in computer storage and processing. A byte consists of 8 adjacent binary digits (bits), each of which consists of a 0 or 1.
What is the term for the transmission of messages and files via a computer network quizlet?

What is data interpretation?
Data interpretation refers to the process of using diverse analytical methods to review data and arrive at relevant conclusions. The interpretation of data helps researchers to categorize, manipulate, and summarize the information in order to answer critical questions.
What refers to process data?
data processing, manipulation of data by a computer. It includes the conversion of raw data to machine-readable form, flow of data through the CPU and memory to output devices, and formatting or transformation of output. Any use of computers to perform defined operations on data can be included under data processing.
What is data input and output?
Input and output, or I/O is the communication between an information processing system, such as a computer, and the outside world, possibly a human or another information processing system. Inputs are the signals or data received by the system and outputs are the signals or data sent from it.
Which type of input and output devices and memory in computer explain in brief?
Keyboards, mouse, scanners, etc are some of the input devices while printers, monitors, headphones, etc are some of the output devices. Another important element of a hardware system is computer memory. It is where all the data goes either temporarily or permanently.
Which type of input and output devices and memory in computer explain in brief and write difference between hardware and software?
