CompTIA A+ Exam prep cert 2

1. 1CPU stands for; [blank_start]central processing unit[blank_end]. The CPU is the brain of the computer itself.

   1. Acentral processing unit
2. 2Every CPU has an i[blank_start]nternal features[blank_end] to process commands

   1. Anternal features
3. 3Every CPU runs code based on a specific [blank_start]machine language[blank_end].

   1. Amachine language
4. 4CPUs use [blank_start]pipelines[blank_end], to optimize the processing commands.

   1. Apipelines
5. 5When we talk about the CPU speed, that is the [blank_start]maximum[blank_end] speed that the CPU can go. The speed of a CPU refers to the “[blank_start]clock speed[blank_end]” or frequency that the processor runs at. It’s called a “[blank_start]clock[blank_end] because it is the digital square wave voltage input that drives the internal processor logic.

   1. Amaximum
   2. Bclock speed
   3. Cclock
6. 6Overclocking refers to [blank_start]pushing[blank_end] your computer components [blank_start]harder[blank_end] and [blank_start]faster[blank_end] than the manufacturer designed them to go.

   1. Apushing
   2. Bharder
   3. Cfaster
7. 7[blank_start]Hyper-Threading[blank_end] is where two threads are able to run on one single-threaded core

   1. AHyper-Threading
8. 8Clock speed is commonly measured in [blank_start]GHz[blank_end].

   1. AGHz
9. 9A CPU [blank_start]cache[blank_end] is a hardware [blank_start]cache[blank_end] used by the central processing unit of a computer to reduce the average cost to access data from the main memory.

   1. Acache
   2. Bcache
10. 10Its common to have three caches in a CPU, [blank_start]L1[blank_end], [blank_start]L2[blank_end], and [blank_start]L3[blank_end]

    1. AL1
    2. BL2
    3. CL3

11. 11A CPU socket is a single connector between a [blank_start]microprocessor[blank_end] and [blank_start]motherboard[blank_end]

    1. Amicroprocessor
    2. Bmotherboard
12. 12CPUs come in [blank_start]32-bit[blank_end] and [blank_start]64[blank_end]-bit versions.

    1. A32-bit
    2. B64
13. 13Operating systems come in both [blank_start]32-bit[blank_end] and [blank_start]64[blank_end]-bit versions.

    1. A32-bit
    2. B64
14. 14Most 64-bit processors also run into 32-bit mode.

    1. ATrue
    2. BFalse
15. 15When installing a CPU, make sure you have the right [blank_start]socket[blank_end] and [blank_start]speed[blank_end] for your motherboard.

    1. Asocket
    2. Bspeed
16. 16Always use [blank_start]thermal paste[blank_end] between the CPU and the fan.

    1. Athermal paste
17. 17Always multiply [blank_start]x8[blank_end] to get the PC speed rating

    1. Ax8
18. 18If you’re holding two different sticks of RAM, and you don't have the notches memorized so you can’t tell them apart, and the sticks don’t say DDR or DDR2, all you need to do is look at the [blank_start]PC rating[blank_end]. If the PC rating says just “PC-”, then we know that it's [blank_start]DDR[blank_end]. If it says “PC2-”, then we know that its [blank_start]DDR2[blank_end], just by looking at the speed rating.

    1. APC rating
    2. BDDR
    3. CDDR2
19. 19[blank_start]DDR4[blank_end] is the fastest ram thats described on the CompTIA exam

    1. ADDR4
20. 20Different motherboards, support a specific [blank_start]RAM[blank_end] technology.

    1. ARAM
21. 21We measure RAM speeds using [blank_start]DDR[blank_end] or [blank_start]PC[blank_end] ratings.

    1. ADDR
    2. BPC
22. 22Multiply a [blank_start]DDR[blank_end] speed by eight to get the PC speed.

    1. ADDR
23. 23Ram is almost always sold in pairs; the reason for this is because pretty much all motherboards use this concept called [blank_start]channels[blank_end].

    1. Achannels
24. 24RAM comes in [blank_start]single[blank_end] and [blank_start]double-sided[blank_end] versions.

    1. Asingle
    2. Bdouble-sided
25. 25An [blank_start]SPD[blank_end] chip is built into every RAM stick on earth.

    1. ASPD
26. 26An SPD chip stores information about the [blank_start]RAM[blank_end] stick.

    1. ARAM
27. 27[blank_start]ECC[blank_end] ram is only for motherboards that support it.

    1. AECC
28. 28[blank_start]Parity[blank_end] and [blank_start]ECC[blank_end] RAM contain extra chips to check for RAM errors

    1. AParity
    2. BECC
29. 29When installing RAM, use the [blank_start]motherboard[blank_end] [blank_start]book[blank_end] to make sure you're installing the right capacity and RAM speed.

    1. Amotherboard
    2. Bbook
30. 30Watch when the system boots to verify the system sees the installed [blank_start]RAM[blank_end].

    1. ARAM
