Which Three Parts Of The Computer Receive Input
1 Motherboard The board allows all the parts of your computer to receive power and communicate with each other.
Components Of The System Unit And Their Functions
3 Central Processing Unit 3 part of CPU or Arithmetic/logic unit (ALU) Contains instruction execution circuit or Control unit Accesses and decodes program instructions in sequence Coordinates flow of data into and out of the ALU or Registers Storage in the processor
5 Central Processing Units and Random Access Memory (continued) Does data flow between processors? o Random access memory Temporary, or non-volatile, storage
7 Front Side Bus The front side bus (FSB) is an electrical path on the computer wall that connects various hardware components to the central processing unit (CPU). This bus is bidirectional, meaning data can flow in both directions, allowing components to send and receive data from the CPU. the computer will depend on its speed. The speed depends on the width of the bus
8 ChipSets Chipsets are the “glue” that connects the microprocessor to the motherboard It has two main parts – northbridge and southbridge Northbridge: The Northbridge connects directly to the processor via the front side bus (FSB). The memory controller is on the north bridge, which gives the CPU faster access to memory.
Input & Output Devices
9 Southbridge: Southbridge is slower than northbridge Information from the CPU must pass through the bridge before reaching the southbridge The southbridge chipset handles all the I/O functions of the computer, such as USB, audio, serial, system BIOS.
12 Slots AGP: Accelerated Graphics Port AGP video cards are capable of higher transfer rates than PCI video cards.
16 The date December 31, 1969 is the time date (representing this number with all bits being zeros) When your system resets the system clock, it will be reset to the current date The current information is not stored in a file, rather it is connected. from your hardware clock and /sbin /hwclock on boot. This visible date usually means that your system clock has been reset, this is usually caused by a faulty battery on your system board (CMOS battery)
18 Machine Instruction Processing involves two phases: o The instruction phase, the execution phase o The two phases together form the machine cycle.
Basic Parts Of A Computer And What They Do
19 Machine Cycle (continued) Command Phase o Step 1: Get the command o Step 2: Cancel Execution Phase o Step 3: Execute the command o Step 4: Save the result
21 CPU Features System Clock o Produces a series of electronic pulses at a predetermined rate called clock speed Clock speed — Measured in megahertz (MHz) or gigahertz (GHz) Word Length o Number of bits that can be processed of CPU simultaneously MIPS. – Millions of instructions per second o Total time required to execute instructions Cache — measured in MB or KB o Temporary storage FSB Speeda GHz/MHz)
23 Multiprocessing and Parallel Processing Multiprocessing o Using more than one processor o Examples: Parallel processing Combining several microprocessors to work at the same time Multi-core processing o Combining two or more processors on one chip.

A keyboard is an essential tool for anyone who spends a lot of time at a computer when the computer accepts input. It allows you to enter text, numbers and other commands quickly and easily. A good keyboard should have a responsive keyswitch design that ensures correct keystrokes every time you type.
In addition, it must be comfortable to use because prolonged typing can cause hand pain or Saint’s disease (a condition in which compression of the carpal tunnel leads to tingling in various parts of the body).
The types of keyboards range from full-sized keyboards that can be attached or detached from the laptop to slim laptops without a separate keyboard. The best option for you depends on how often you plan to use your laptop and what kind of typist you are. If space is not an issue, a full-size keyboard may be better for you than a small keyboard because it takes up less space.
Solution: Computer System And Its Elements
Mechanical: Mechanical keyboards are the oldest type of keyboard and consist of physical switches that must be pressed to enter text or commands. They are usually heavier than other types of buttons and are often difficult to use. Because they need precise finger movements.
Electronic: Electronic keyboards usually have a number on the left side and include an embedded computer chip that interprets your typing patterns. This type of keyboard is easy to use because you don’t have to search for letters when sending a message or writing an email. But it is not as durable as a mechanical key.
Membrane: The membrane keyboard is based on a thin layer of silicon that is larger than a normal keyboard. When the fabric gets wet (like sweat), it expands slightly allowing it to act like a real key by adding different characters depending on where your finger touches it.
A computer mouse is a small hand-held device that allows you to move the cursor on the screen by moving your hands and arms. The first mouse was developed in 1976 by Douglas Engelbart at IBM Corporation.
Module 5 Unit 2 Understanding Input Devices
A computer mouse is a small device that you use to interact with your computer. It usually has two or more buttons, a scroll wheel and a left button. When you press the left-click button, it sends an electrical impulse to the computer that makes it understand what you’re trying to do.
There are many types of computer mice available these days, but the most common is the optical mouse. This type of mouse uses infrared technology to detect movement and allows you to use it anywhere there is a transmitter or receiver. The standard Microsoft Xbox 360 controller is also an optical mouse.
There are two other types of mice: laser and touchpad. Laser mice use light beams to detect movement instead of infrared sensors. Whereas a touchpad mouse allows for more precise control of the cursor by allowing the finger to be placed on it instead of having dedicated buttons.
Ultimately, the type of mouse that best suits your needs depends on your preferences and usage patterns. Be sure to try different types before deciding which one is right for you!

A computer monitor is an electronic device that displays a video image on the screen as input. Monitors come in a variety of shapes and sizes, and prices start as low as $40. Older monitors use cathode ray tubes (CRTs), while newer models are typically LCD-backlit LCD screens.
Most computers include a VGA or DVI port for connecting an external monitor, so you can view multiple documents or photos at the same time. A good rule of thumb is to have one primary monitor to work with. And another to play games or watch videos.
CRT (cathode ray tube) monitors use an image drawn on the screen by a beam of electrons that interact with the fluorescent material behind the screen.
This has been replaced by LCD monitors as they offer better color reproduction and more natural looking images. Although there are still some applications where CRTs are used. Like gaming and video conferencing, more and more people are using LCDs these days.

LED screens use light-emitting diodes instead of cathodes, resulting in brighter displays with less power than standard CRTs or LCDs. However, LEDs tend to generate more heat than other technologies. And it may not be suitable if you work in direct sunlight or want to keep your workplace cool.
You can tell which part of the computer is receiving input by looking at the cursor on the screen. If the cursor is in a corner of the screen and does not move. Then that part of the computer does not accept input. However, if the cursor is moving (or visible), that part of your computer is accepting the user.
Input is usually from the keyboard and mouse. Input may come from a pointing device, such as a trackpad or touchpad,
