CPU

A CPU is the computer's "brain." It does most of the processing. It accepts instructions from various programs. It executes commands, runs apps, and controls data flow in a computer. In other words, the motherboard connects all the computer's parts. It does this through its circuits and a data path using different chips.

The ALU does calculations and other operations. The Control Unit runs the CPU and coordinates the other computer parts. CPUs also have registers. They are a tiny area. They hold a small amount of data and instructions, in parallel, during processing.

CPU clock speed is measured in gigahertz (GHz). It is the number of cycles per second the processor can perform. Higher values are better. Most processors today have more than one core, like a quad-core. This lets the CPU handle multiple tasks at once. Also, on the CPU level there are three levels of cache memory – L1, L2, and L3 – which stores the most actively used data for faster access by the processor.

Motherboard

The motherboard is a vital computer part. It connects and relays info between all other components. It transfers information within the computer. It also powers different sections. It connects the CPU, RAM, storage, and peripherals. A motherboard links all components. It ensures a computer runs smoothly.

Some of the major parts consist of the CPU socket where the processor is inserted and Ram slot where new memory modules can be fixed. The latest designs use Northbridge or Southbridge, or a single chip. They mediate between the CPU, memory, and peripherals.

Expansion slots, like PCIe, allow adding cards, like the graphics or sound card. Storage connectors, like SATA ports, connect to hard drives or SSDs. Power connectors supply power from the PSU to the motherboard and its parts.

These are mostly the ATX, micro ATX, and mini ITX form factors. They determine the size of the case and the components that can be mounted. Other subsets are the BIOS and UEFI. They are the "Basic Input/Output System" and "Unified Extensible Firmware Interface," respectively. They are controlled by boot hardware and provide access to different system options.

Integrated circuits: Some motherboards have built-in graphics, sound, and network features. So, they need a few expansion cards. A motherboard must have the right CPU socket, the correct RAM type, and enough expansion slots.

RAM

RAM or known physically as the main memory is one of the most important inputs in a computing machine.Here’s some detailed information about RAM:

• Function: RAM is forms of short-term memory that are utilized by the CPU in the storage and fast access of data that are in use or being processed. It lets the computer run apps at their best. It does this by providing a way to read and write data on a much faster storage medium than the hard drive or SSD.

• Volatility:RAM is volatile in nature, it is cleared when the power is shut down. This is different however from non-volatile storage such as hard drives or SSD where data is stored even when the computer is switched off.

• Types of RAM:

• DDR (Double Data Rate):Some of the known kinds of DDR memory include the DDR3, the DDR4 and the most recent one, The DDR5.

• SRAM (Static RAM): This type of memory can access data in two clocks. It was popular for caches. It is more expensive than DRAM.

• DRAM (Dynamic RAM): This is the most used type of RAM in computers. It needs periodic refreshing to retain its data.

• Capacity: Given in gigabytes (GB), RAM defines the amount of data that can be processed simultaneously at the operational speed. More RAM lets a computer run more apps at once. It also helps with memory-intensive tasks. These are real-life examples of its benefits.

• Speed: The RAM speed is in the form of MHZ(megahertz) or GHz(gigahertz) and determines how swift data can be retrieved from the RAM or written to it. Performance generally improves with higher speeds.

• Channels: The memory may connect to the motherboard in different channels, like two or four. This can increase bandwidth and improve memory performance.

• Form Factor: RAM types include DIMM that is used in desktops and SO-DIMM that is used in laptops among others. When choosing the cooling solution the form factor should also correspond to the motherboard.

• Latency: It's the delay after a data transfer instruction. Lower latency means faster performance.

• In general, RAM can be considered as a crucial factor that defines the fast running speed and capacity of a computer for multitasking. The more the RAM, the more the system is able to juggle several applications and big files at the same time..

Hard  drive

The hard drive also known as hard disk drive-HDD is one of the important elements in a computer required in storage. Here’s a detailed overview:

• Function: The hard drive is the computer's 'memory'. It holds your documents, apps, OS, music, and photos or videos. It offers long-term storage known as nonvolatile that is stored even when the computer is switched off.

• Components:

• Platters: Discs coated with magnetic material where data is stored. They spin at high speeds.

• Read/Write Heads:Reading or writing data on the platters, these heads are installed above the platters.

• Spindle: Drives that cause  the rotation of the platters.

• Actuator Arm: In an actuator arm, the read and write heads move along the platters.

• Storage Capacity: The storage capacity is stated in GB or TB, and it indicates how much data the drive holds in it.

• Speed: Hard drives are classified by the number of rotations per minute (RPM for short). These are usual rotational speeds and the higher the RPMs are, the quicker data is accessed out of drive; or they are 5400 and 7200 RPM.

• Form Factor: Hard drives come in various sizes. Of these, 3 are the most common. 5 inch for desktop computer and 2 inches for laptop. 5 inches for laptops. External hard drives may use different sizes and connectors.

• Interface: Basically, the interface helps in linking the hard drive to the computer. SATA, or Serial ATA, are the most popular drive interfaces. IDE, or Integrated Drive Electronics, is an older interface. SAS (Serial Attached SCSI) is utilized on the high I/O, or enterprise level applications.

• Reliability and Durability: Hard drives are mechanical devices. They have many moving parts. So, they are less resistant to physical shocks than SSDs. Their usage and handling should be done in a correct way so that they can be of service for many years.

• Comparison to SSDs: Unlike traditional hard drives, SSDs use flash memory. They have no moving parts. They are faster, more durable and more energy efficient but their cost per gigabyte may be high.

• Hard drives store data permanently. Solid state drives are replacing them. They are faster and more reliable in today's high-tech world.
