What does CPU stand for? Core processing unit Computer processing unit Central processing unit
What is Central processing unit. The central processing unit (CPU), or the microprocessor, is the heart of your desktop of laptop computer, a tiny chip that contains an entire computation engine on top.

1.What does rpm stand for?
Answer: Revelations per minute
100
The back panel has connections for. A.Mouse B.Keyboard C.Speakers All of the above
What is All of the above
100
640 by 480 is an example of A.Resolution B.Aspect Ratio C.Refresh rate D.Screen size
What is Resolution

The most common form of RAM is: A.Dynamic RAM B.Static RAM C.VideoRAM
What is Dynamic RAM. In dynamic RAM (DRAM), the most common type of RAM, a transistor and a capacitor pair up to make a memory cell. The capacitor holds a bit of information (in the form of a 1 or 0), while the transistor acts as a switch, allowing the control circuitry to change the state of the memory.

What is a CPU’s clock speed? A.the accuracy of time-keeping function B.the number of times a second it refreshes its memory C.the rate at which it can execute instructions
What is the rate at which it can execute instructions The clock speed indicates how quickly the CPU can execute instructions. The frequency is measured in megahertz or gigahertz.

2.What is the different Between PATA and SATA drives a. need a controller that operates the interface between drives and the computer motherboard. b. SATA uses less energy c. Uses semiconductors
Answer: SATA uses less energy
200
What is the main difference between AT, ATX and MicroATX motherboards? A.The kind of power supply required. B.The kind of CPU. C.The number of on-board devices. D.The physical dimensions. E.None of the above.
What is D.The physical dimensions.

A monitor’s resolution refers to A.The number of colors it can display B.The width of the display C.The number of pixels from width to height D.The displays brightness
What is C.The number of pixels from width to height
300
How often does a memory controller automatically refresh memory in dynamic RAM? A.Once every minute B.A few times per second C.Thousands of times per second
What is Thousands of times per second. Dynamic RAM needs to automatically refresh thousands of times per second; that's where it gets the name "dynamic." Otherwise, it will forget the information it's holding.
300
The memory that a CPU can use directly is called: A.cache memory B.clock memory C.direct access memory
What is cache memory However instantanous the actions of a computer seem to be sometimes, every little operation takes time. Retrieving data from the cache, however, is much faster than retreiving from system memory.

3. What is a partition?
Answer: the different segments you can divide a hard drive into

Question 1 Which part of a traditional motherboard is also known as the memory controller hub? A Southbridge B Northbridge C BIOS D PCI Bus
What is North bridge. One of the primary tasks of the Northbridge is the management of communication between the CPU and the memory.
300
LCD monitors often have a smaller __________ than CRT monitors. A) refresh rate B) viewing angle C) color depth D) price
What is B) viewing angle
400
What sets static RAM apart from dynamic RAM? A.Dynamic RAM is faster than static RAM. B.Static RAM is faster than dynamic RAM. C.There isn't much of a difference between static and dynamic RAM.
What is Static RAM is faster than dynamic RAM. Because static RAM requires anywhere from four to six transistors and some wiring, the memory never has to be refreshed. It's therefore faster than dynamic RAM. Because it has more parts, though, it takes up more space on a memory chip, which gives the chip less memory and makes it more expensive.

A turbo boost allows a CPU to: A.rev up its cooling fan B.run at a speed faster than that for which it’s rated C.access the hard drive directly
What is run at a speed faster than that for which it’s rated Turbo boost increases the power and speed of a CPU when more processing power is needed.

4.Which of the following are benefits of a SSD Drive? A. Faster read and write speeds B. More expensive C. Use semiconductors to store data
Answer: A and C
400
Which motherboard chipset commonly connects to USB ports? A Front-side Bus B Southbridge C PCI Bus D Northbridge
What is Southbridge. The Southbridge chipset has traditionally connected slower-speed peripherals such as USB ports, SATA interfaces, and Ethernet connections.
400
What is commonly wrapped inside the bezel of the laptop screen? A Memory B Antennas C USB ports D HDMI port
What is Antennas. It's common to wrap the WiFi, bluetooth, and other antennas around the display, since it's the highest point of the laptop when the display is opened.
500
How does virtual memory free up RAM? A.It partitions the computer's operating system, freeing up RAM in the process. B.It looks for data in RAM that hasn't been used much, copies that data to the hard drive and frees up RAM for other processes. C.It converts other kinds of memory into RAM temporarily on an as-needed basis.
What is It looks for data in RAM that hasn't been used much, copies that data to the hard drive and frees up RAM for other processes. Virtual memory looks at RAM for areas that have not been used recently and copies them onto the hard disk. This frees up space in RAM to load new applications.
500
The type of processing where multiple instructions are sent to more than one processor to execute at the same time is called: A.word processing B.data processing C.parallel processing
What is parallel processing. Many of today's CPUs include multiple processing cores, allowing the divvying up of instructions to speed up processing. It should be noted that two cores don't double speed, as there are other factors at play.

5. Why is the NTFS format not preferred when using the OSX
Answer: OSX can only read that format and can not write to it.

In a traditional Northbridge/Southbridge motherboard architecture, where would you expect to see the video adapter connected? A Northbridge B Southbridge C FSB D PCI Bus
What is Northbridge. Question 3 Explanation: If it's a part of the computer that needs a lot of bandwidth, then you can bet that it's connected to (or near) the Northbridge. Lower bandwidth devices are often found near the Southbridge.

Which of these are commonly used with laptop LCD display to provide power to the backlight? A Default resolution B Modulator C Inverter D Magnetic switch
what is Inverter An inverter is commonly used with laptop displays that are backlit with cold fluorescent light (CFL) tubes. These tubes use a higher-voltage AC power source, and the inverter is used to convert the incoming DC power to AC.
