Computer Skills Placement Objectives CSP questions and
answers
Hardware - -Computer case, keyboard, and monitor
-Sofware - -Organized information in the form of operating
systems, utilities, programs, and applications that enable
computers to work.
-Information Technology (IT) - -Any computer-based tool that
people use to work with information and support the information
and information-processing needs of an organization
-Central Processing Unit (CPU) - -Brain of the computer that
performs instructions defined by software
-Hard Disk - -A data storage unit inside a computer that can store
a large quantity of data (60GB or more)
-Input - -Data that is entered into the computer system via an
input or storage device.
-Output - -Data that is send out of the computer.
-Peripheral Device - -Devices that communicate with the CPU but
are not located directly on the motherboard(not part of the
computer), such as the monitor, floppy drive, printer, and mouse.
-CPU Speed - -Measured in MHz (Megahertz) or GHz (Gigahertz).
Also referred to as the CPU clock.
-RAM Speed - -Measure in MHz or Bytes. This measured the
amount of time it takes the module to deliver a data request
-CPU Functions - -Fetch, Decode, Execute and Store
, -Fetch - -Each instruction is stored in memory and has its own
address. The processor takes this address number from the
program counter, which is responsible for tracking which
instructions the CPU should execute next.
-Decode - -Decode: All programs to be executed are translated to
into Assembly instructions. Assembly code must be decoded into
binary instructions, which are understandable to your CPU. This
step is called decodin
-Execute - -While executing instructions the CPU can do one of
three things: Do calculations with its ALU, move data from one
memory location to another, or jump to a different address.
-Store - -The CPU must give feedback after executing an
instruction, and the output data is written to the memory.
-Random Access Memory(RAM) & Read Only Memory (ROM) - -
RAM is used for both read and write while ROM is used only for
reading.
-Random Access Memory(RAM) & Read Only Memory (ROM) - -
RAM is volatile and is erased when the computer is switched off.
ROM is non-volatile and generally cannot be written to.
-How is computer memory measured? - -Megabytes(MB) and
Gigabytes (GB)
-1 MB - -1024 * 1 KB = 1,048,576 bytes
-1 GHz - -1024 MB
-1 byte - -8 bits
-Touchscreen - -Input/output device, electronic visual display that
can detect the presence and location of a touch within the display
area
-Diskette stored - -cost $.50 and stored 1.4MB.
