Study Notes
The CPU: Brain of the Computer
- A CPU (Central Processing Unit) is a single silicon-based electronic chip that enables a computer to function.
- The CPU is also referred to as a microprocessor.
- CPUs are found in various devices, including desktop computers, laptops, smartphones, smartwatches, and even appliances like washing machines.
CPU Structure and Components
- The CPU is typically located on the motherboard, hidden beneath a heat sink and often a fan assembly.
- CPU manufacturers assign names to their microprocessors, similar to the automobile industry, including make and model (e.g., Intel Core i9, Qualcomm Snapdragon 8 Gen 1, or AMD Ryzen 7).
Overview of the Chapter
- The chapter explores microprocessors in detail, covering their inner workings, components, and interactions with the rest of the computer.
- The chapter is divided into five sections: how processors work, CPU-memory interactions, modern CPUs, selecting and installing CPUs, and troubleshooting CPUs.
SSD (Solid-state Drive)
- A type of storage that uses all memory and has no moving parts
- Characteristics: silent, fast access time, and less latency
- Available in 2.5 inch and 1.8 inch form factors
Hybrid Drive (SSHD)
- A type of storage that combines flash memory and hard drive storage
- SSD caches the hard drive data
- Uses a magnetic disk with traditional spinning drive platters
Replacing Laptop Storage
- A relatively modular process
- Typically involves removing two screws and sliding the drive out
- All internal components are accessible by opening a cover on the back or the entire laptop
Laptop Memory
- Uses SO-DIMM (Small Outline Dual In-line Memory Module) or Micro-DIMM (Micro-Dual In-line Memory Module)
- Specifically designed for laptops and mobile devices
Smart Card Reader
- An integrated card reader built into the laptop
- Can also be an external reader connected via USB
Optical Drive
- Not commonly used in portable devices due to size constraints
- Becoming less common in modern laptops
- Often removable and can be replaced with other media
- Capable of reading and writing CD-RW/CD-ROM and DVD-RW/DVD-ROM
Video Cards
- Often built into the processor and not upgradable
- Sometimes part of the system board and not upgradable
- Some laptops have upgradable video cards, but not the slimline models
Learn about the Central Processing Unit, its structure, and components that enable computers to function. Discover how CPUs are found in various devices and their role in the motherboard.
