10 - Input, Process, Output, Data Bus

 1. Computers have come a long way from the commercial computer in the picture below. In essence however, a computer system: 
....takes a set of digital _________, ____________ them, and creates
a set of _________. This is done by a combination of Hardware and
Software.

  inputs / processes / outputs

  signals / sends them / prints

  bits / inputs / outputs

  processes / inputs / hardputs

 2. One of the first ever 'mice' (computer mouse) looked like the image below. It is an example of a ......

 5. A touch screen picks up finger movements on the screen and produces input data for the computer system. It is an input device.

  True

  False

 6. A LED Light lights up when a signal is sent to it. It is an example of .....

  an output device

  an input device

  a storage device

  a processing device like the CPU

 7. Along with input and output devices, there are also __________ devices, which allow a computer to store data for future use.

  programmable

  CPU

  neumann

  storage

 8. We know how data is input, output and stored, but how does data move around the system?

  via binary bits

  on a bus

  via electricty

  through the ALU

 9. Modern computer buses can use both parallel and bit serial connections, and can be wired in either a multidrop (electrical parallel) or daisy chain topology, or connected by switched hubs, as in the case of USB 
Buses can be parallel buses, which carry data words in parallel
on _________ wires, or serial buses, which carry data in bit-serial 
form

  single

  multiple

  super charged

  copper

 10. Read the excerpt below on Buses and fill in the blanks. 
Buses are circuits on the motherboard that connect the CPU to other 
components. There are many buses on the motherboard. A bus moves 
instructions and data around the system. The ______ of a bus is 
measured in megahertz (MHz). The faster the bus, the faster data 
is communicated. The speed of the motherboard is defined by the bus 
speed. Buses are limited by their width in bits. They are usually 
8, 16 or 32-bits wide. This tells us how many bits can be sent 
by the bus at any one time, eg a 32-bit bus can send 
_____ bits at once.

There are three types of bus:
1.D_________ Bus
2.A__________Bus
3.C__________Bus
