CPU
CPU stands for Central Processing Unit
What is RAM?
RAM (Random Access Memory) is a type of volatile memory that provides temporary storage for data that the CPU is actively using.
Differentiate between hard disk drives (HDDs) and solid-state drives (SSDs) in terms of their technology and advantages.
HDDs use spinning disks and mechanical read/write heads to store and retrieve data. They are less expensive per gigabyte and have larger capacities but are slower and less durable.
What are input devices, and why are they essential in computing?
Input devices are hardware components that allow users to provide data or commands to a computer. They are essential in computing because they enable interaction and communication between users and machines, allowing users to input information, control software, and perform tasks.
Describe ESD (electrostatic discharge)
ESD (electrostatic discharge) is similar to a "static shock" -- it's a sudden transfer of voltage between two unlike surfaces.
What is its primary function in a computer?
Its primary function in a computer is to execute instructions and perform calculations. It acts as the "brain" of the computer, processing data and controlling the operation of all other hardware components.
Explain one common use of ROM in all computers
ROM (Read-Only Memory) is a type of memory that stores the BIOS and essential system instructions. It contains data that cannot be modified or erased by typical computer operations.
What is the role of optical drives in modern computing?
Optical drives like DVD and Blu-ray drives are used to read and write optical discs.
What are output devices, and how do they differ from input devices?
Output devices present information generated by the computer to the user. They differ from input devices, which provide data to the computer.
Describe one way to prevent ESD (electrostatic discharge)
Touch metal on the case, wear an ESD strap, use an ESD mat
What is the difference between a CPU and a GPU?
A CPU (Central Processing Unit) is the primary processor in a computer responsible for general-purpose computing tasks, while a GPU (Graphics Processing Unit) is specialized for rendering graphics and performing parallel processing tasks.
How many pins does DDR2 and DDR3 have - and also - how many does DDR4 and DDR5
DDR2 & 3: 240 pins
DDR4 & 5: 288 pins
What is the purpose of a USB (Universal Serial Bus) port, and what are some common devices that connect to USB ports?
USB ports are versatile and used for connecting a wide range of devices, including external hard drives, flash drives, keyboards, mice, printers, smartphones, cameras, and other peripherals. They facilitate data transfer and power delivery.
True or false, the I/O shield on the back of all standard motherboards is identical
True! Whether an ATX, microATX, or mini-ITX form factor, the IO ports and shield will always be in the same spot with the same dimensions.
What should a tech remove or secure on their personal self before working inside a case/server?
Jewelry, ties, long hair, loose clothing
What makes a PGA CPU different from a LGA CPU?
What are pins instead of gold contacts?
Differentiate between volatile and non-volatile memory?
Volatile memory, like RAM, is temporary and loses data when the power is turned off. Non-volatile memory, like SSDs and ROM, retains data even when the power is off.
What does the term "formatting" mean in the context of storage devices?
Formatting refers to the process of preparing a storage device for data storage.
Which part of the chipset handles slower communication, such as USB ports?
The South Bridge
Which has the smallest form factor: ATX, mini-ITX, micro-ATX, ?
Mini-ITX
Regarding cooling systems, describe the difference between Active cooling and Passive cooling
Active involves motion (fans, pumps), while passive simply radiates heat into the air (like a cellphone, Roku, etc)
Where is "Static RAM" commonly used?
CPU caches
Describe the concept of data backup and its importance in data storage.
Data backup is the practice of creating copies of important data to protect against data loss. Common backup methods include external hard drives, cloud storage, network-attached storage (NAS)
Which part of the chipset handles fast communication, such as the CPU and RAM?
Northbridge
What is the official term used to describe the AGP or PCI-e ports on a motherboard, commonly used to add video cards, network cards, etc?
Expansion slots
