Is a barcode scanner an input or output device?
A bar code scanner is an input device. While it does contain a laser, the laser is used to read the data, not to communicate anything to the user. The bar code scanner reads the UPC codes into the cash register or point of sale system.
What is any hardware component used to enter data?
input device
In the early computers what was used to input data?
Back in the day computers input data by a CD ROM. In today's computer all you have to do is have a hard drive.
A stylus is a small device resembling?
a pen and its used to input data
What is the definition of a hash in computer science and how is it used in computing systems?
In computer science, a hash is a function that converts input data into a fixed-size string of characters. This string, known as a hash value, is unique to the input data. Hashes are commonly used in computing systems for tasks like data encryption, data integrity verification, and indexing data for quick retrieval.
Memory address register is used to store?

What is rim in microprocessor 8085?
RIM is Read Interrupt Mask. It is used to access the interrupt mask register, which contains the status of the three interrupt masks and the serial input data pin.
What is input mask as used in database?
An input mask is a pattern or template used to control the input of data into a database field. It defines the acceptable format for data entry, such as phone numbers, dates, or social security numbers. Input masks help ensure data consistency and accuracy by guiding users to input data in a specific format.
What is data register?
It is used to hold data or the memory address that contains either the next place of data or an instruction that is to be used .
What are input devices at realtors?
The devices that are used for input data in the computer are called input devices in realtors
What are the different types of segment register?
The code segment (CS) register is used for access to program code. The data segment (DS) register is used for access to data. The extra segment (ES) register is used for access to data during certain string primitive operations. The stack segment (SS) register is used for access to stack data.Any of these implied uses can be overridden with a segment override prefix opcode.

Why a latch is used for an output port but a tri-state buffer can be used for an input port?
The Latch will hold the data until new data will changes from input of Buffer.
What is the difference between input and Read data statement?
The INPUT statement in programming is used to read data from user input during the execution of a program, allowing for dynamic data entry. In contrast, the READ statement typically retrieves pre-defined data from a specified source, such as a file or data structure, and is often used in conjunction with data storage formats. Essentially, INPUT is interactive, while READ is more about accessing existing data.
What is function of keyboard keys?
The keyboard is an input device the keys are used to input data into the computer
