8) U.S.B. - (Universal Serial Bus) is an industry standard developed in the mid-1990s that defines the cables, connectors and communications protocols used in a bus for connection, communication, and power supply between computers and electronic devices. 9) H.D.D.-(Hard disk drive) is a data storage device used for storing and retrieving digital information using rapidly rotating disks coated with magnetic material. HDD retains its data even when powered off. Data is read in a random-access manner, meaning individual blocks of data can be stored or retrieved in any order rather than
– Used for: • Digital cameras • Video cameras – 1394a—FireWire 400 • 400Mbps – 1394b—FireWire 800 • 800Mbps Like USB, devices are hot swappable. 17 Other Common Ports PS/2: – Used for legacy motherboard connections to keyboard/mouse.

This video explains the purpose of the ports and devices. * Serial Port: Transmits data 1 bit at a time. A serial port is a general-purpose interface that can be used for almost any type of device, including modems, mice, and old printers * Parallel Port: Transmits data 8 bit at a time. A parallel interface for connecting an external device such as a printer. the parallel port uses a 25-pin connector (type DB-25) and is used to connect printers, * Gaming Port: 15 pins, * Mouse and
The ADC may be used in simple digital display devices e. g. thermometers, light meters but it may also be used in digital sound recording and in data acquisition. However, a digital-to-analogue converter (DAC) is used to change a digital signal to an analogue signal. A DAC takes a series of binary numbers and converts it to an analogue signal. It is common to find a DAC in the gain-control system of an op-ampwhich in turn may be used to control digital amplifiers and
A COMPILER is a program that translates a high-level language program into a separate machine language program. An INTERPRETER is a program that both translates and executes the instructions in a high-level language program What type of software controls the internal operations of the computer’s hardware? An operating system controls the internal operations of the computer’s hardware Unit 1 Research Assignment 1 Algol (ALGOrithmic Language): 1960, Defined by an international consortium.

Explain in 1-2 sentences. (1.0 points) I would use digital because ONE I could re-record something if I had to and not worry about wasting recording tape and be able to get the sound I want perfect and not having to settle with the first recording I do. And second I would be able to edit my recording a lot easier and be able to use more editing tools on a digital recording than on a analog
Many control panels are included as part of the Windows operating system, but others can be installed by third-party applications or utilities. For example, if you add a new mouse to your computer, it may come with a CD for installing a control panel specific for that mouse. Some graphics cards may also install an additional control panel that gives the user greater control over the computer's visual settings. Regardless of when control panels are installed, they can always be found within the Control Panel folder. The Windows Control Panel can be accessed by clicking the Start menu and selecting Control Panel.
