Question

List the seven basic internal components found in a computer tower

Answer 1

1. Motherboard (you plug all other components to it)
2. Processor (CPU)
3. Memory (RAM)
4. Graphics card
5. Sound card (sometimes integrated with motherboard)
6. Hard Disk Drive (HDD)
7. Power supply unit

Answer 2

1)Processor(CPU)-It is or it acts as a "brain" of the computer.It controls the working of all of the hardware and software.It is a logic circuitry that responds to and processes the basic instructions that drive a computer.Its four primary functions are fetch,decode,execute and write-back.
The main components of computer processor are:
i)control unit-which fetches,decodes,executes instructions.
ii)Arithmetic& logic unit(ALU)-which performs arithmetic and logical operations on data.
iii)Registers- which holds instructions and other data..they supply operands to the ALU and store the results of operations.
iii)system clock-the clock is a quartz controlled oscillator supplying timing signals at a fixed rate The signals are used to regulate the execution of instructions and to synchronize the operation of the computer components.
2)Motherboard-it is a computer hardware that holds together many of the crucial components of a computer including the CPU,memory and connectors for input and output devices.
so it serves as the central circuit hub that connects all peripherals.it also regulates the power recieved by the hard drive,graphic cards,CPU and system memory from the power supply.
3)Random access memory(RAM)-It s a form of computer data storage that stores data and machine code currently being used.it is a volatile memory.
4)Hard drive-This is a none-volatile memory hardware device that permanently stores and retrieves data on a computer.
5)Power supply unit-This is the component that converts mains i.e AC to low-voltage regulated DC power from the wall into the right kid of power for the individual parts of the computer.
6)Video card-This is an expansion card which generates a feed of output images to a display frequently.
7)Network card-This is an electronic device that connects a computer to a computer network usually a LAN(local area network)
