COMPUTER HARDWARE AND COMPONENTS
Computer Basics Equipment (Hardware) COMPUTER | A machine that processes information and performs computations. | Tower or
Desktop | The "box" or case that holds the parts that make up a computer: CPU, hard disk drive, floppy drive, memory chips, power supply, interface cards, etc. Click here to learn more. | | CPU | Central Processing Unit, or "brains" of the computer | Monitor | An output display device (looks similar to a TV) in a computer system. You see information on the monitor's screen. | | Screen | The viewing area on a monitor or the information or image displayed. | | | | Disk Drive | A device that reads data from (input)

The printer on the left is an INK JET PRINTER, and the other is a LASER PRINTER. | . | . | Hub | | | -------------------------------------------------
Hubs are devices that have many ports into which network cables are plugged. A hub takes the signal from each computer and sends it to all of the other computers through the network. Hubs come in different sizes and colors. The hub must be plugged in and turned on for the network to work - be sure you see green lights | Modem | A device that allows computers to communicate with each other over telephone lines (Internet). At school we do not use modems, we have a direct connection to the Internet called a T-1 line. | Keyboard | Input device - choose letters, symbols, and actions by pressing keys
| Key | Any of the buttons on a keyboard that the user presses to input data (information) or to type commands | Escape | Usually pressed while you are working in a software application to stop the current activity, back out of a menu (or screen), or return to a previous screen. | Enter | Used to move the cursor to the beginning of a new line. It may also be called the return key. In some applications, pressing Enter tells the computer to stop waiting for more input and begin processing. Notice the arrow symbol on the Enter key; it is sometimes used in instructions and means to press the enter key. | Backspace | Moves the
In addition, they are comfortable to utilize as well. Use the I, J, L and K buttons to move in different directions. You may similarly choose to utilize the arrow keys rather than using these buttons. The space bar is used to dive tackle or continue, whereas the M button is used to mute the sound.
Input: An input is when a computer receives data from external hardware such as a mouse, keyboard
&& // is a logical and operator that if both the operands are non- zero, then the condition becomes TRUE.
It is in most cases used to connect multiple local area networks together to form a bigger network.
transmission of structures to generate digital indicators distorted by the loss of the transmission. Hubs function as repeaters by transmitting messages to the related computers. The repeater does intellectual routing that can be acted upon by routers and bridges (Vachhani,
HUB - An Ethernet hub, active hub, network hub, repeater hub, multiport repeater or hub is a device for connecting multiple Ethernet devices together and making them act as a single network segment.
Answer: hardware and software is the core of the computer without it computer cannot perform its task. The PC contains various electronic components that we are able to see when we open it. By only pc by itself cannot perform their task on their own. Our PC needs something to get instructed to set it on where we need software to perform it. There are six different component of hardware to function the computer .The first one is central processing unit(CPU )it is the brain of the
Ethernet is typically the technology that is used to allow computers locally to communicate with one another. Computers that are close to each other they are connected by Ethernet.
a. You input information perhaps via a keyboard or mouse to the computer and you receive output via a monitor or printer or some such device
The CPU is housed in the motherboard is considered the heart of the computer, it controls everything. CPU stands for central processing unit; it is one of the main components of a computer. The CPU or more commonly known as the processor is electronic circuitry which follows the instructions of the hardware and software on the computer, it effectively is a very efficient calculator carrying out arithmetic, logical, control and input/output operations.
A dash can be a
Computer only understand 0 and 1 so everything typed on the keyboard input tab CPU convert into 0s and 1s.e.g. If you input the number 230 and 60 and want to have a result of the sum of these two numbers computer do not understand this number. These numbers go to the RAM then to CPU. Inside CPU electronic component known as control unit receive order from RAM in form of instruction then it breaks down into specific commands for others components.
The _________ is a term for the device or unit that receives the information transfer.
Star – All computers and devices are connected to a centrally situated hub or switch. The hub or switch collects and distributes the flow of knowledge at intervals the network. It’s higher to use a switch than a hub as a result of a switch transmits the info to the supposed recipient instead of to all or any hosts on a network.
The function of the processors is to run programs and send and receive signals from the connected devices to keep computer running. Processors handle all the data and runs all the programs that allow you to complete your tasks.
