1Memory VOLATILE
- AOnly stores information to run programs while the PC is off.
Don`t requires electricity to store data using transistors and capacitor - BRetains data even when the computer is off. Examples in old computers: paper, punched tape
and floppy disks - COnly stores information to run programs while the PC is on. Reset when the PC is
turned off. Requires electricity to store data using transistors and capacitor - DDon`t retain data even when the computer is on. Examples in old computers: paper, punched tape
and floppy disks
- AOnly stores information to run programs while the PC is off.
2Memory NON-VOLITILE
- ARetains data even when the computer is off. Examples in old computers: paper, punched tape
and floppy disks - BReset when the PC is turned off.
- CRequires electricity to store data using transistors and capacitors
- DRetains data even when the computer is on.
- ARetains data even when the computer is off. Examples in old computers: paper, punched tape
3Latency is the time for components to [blank_start]respond to a request[blank_end]
- Arespond to a request
4Bridges
- Ais the area where the computer stores or remembers data.
- BManage how data and instructions are transferred between devices
- Cprovides the CPU with its instructions.
- DPrimary storage
5Cores
- AManage how data and instructions are transferred
- Bis the time for components to respond to a request
- Ccommunicate through channels therefore doubling cores does not double speed
- DRetains data even when the computer is off.
6Memory
- AExecutes programs using the fetch-decode-execute cycle
- BUsed to access the performance of a computer.
- CExamples Registers, cache, RAM, ROM and Virtual
- DStores program operations and data while the program is being executed.
Memory
7Storage means
- ARenders images, frees up the CPU for other tasks
- BRetain programs and files long term, even when not in use.
- Cexecutes programs using the fetch-decode-execute cycle
8Benchmarking means
- AA test used to access the performance of a computer. Different types of software are used depending on the computers purpose.
- BStores program, operations and data while the program is being executed.
- CRegisters, cache, RAM, ROM and Virtual Memory
- DCPU speed (cycles per second)
9Computers require an input hardware, processing hardware and output hardware.
- ATrue
- BFalse
10CPU speed (cycles per second) measured in .............................
- AGigabytes
- BROM
- CRAM
- DHertz
11Factors that affect CPU performance are
- AProcessor type, cache, clock speed
- BProcessor type and cache
- CProcessor type and clock speed
- DOnly cache
12Cache is a small amount of memory which is a part of the CPU - closer to the CPU than RAM. It is used to temporarily hold
instructions and data that the CPU is likely to reuse.- ATrue
- BFalse
13The CPU control unit checks the -------------------- for instructions before the RAM.
- AOperating system
- BMemory
- CClock
- DCache
14Larger the Cache =
- Aindicates how fast the CPU can run.
- Bdetermines how many instruction cycles the CPU can deal with in a second.
- Cless data can be stored closer to the CPU
- Dmore data can be stored closer to the CPU
15The clock speed - also known as clock rate -
- Adepends on the size of the cache
- Bindicates how fast the CPU can run.
- Cstores programs, data and instructions.
- Dallows the communication between devices
16Clock speed is measured in megahertz (mHz) or gigahertz (gHz)
- ATrue
- BFalse
17Clock speed is measured in megahertz (mHz) or gigahertz (gHz) and corresponds with how many instruction
cycles the CPU [blank_start]can deal with in a second[blank_end].- Acan deal with in a second
18CPU can contain one or more processing units also known as
- Acores
- Bbenchmark
- CRisc
- DSisc
19Grapnics bus PCI Express is
- Aa test used to access the performance of a computer.
- Bused to render images, frees up the CPU for other tasks
- Cto store programs andfiles long term, even when not
in use. - Dexecutes programs using the fetch-decode-execute cycle
20RISC stands for
- ARandom information set comunication
- BROM instruction safe comunication
- CRisk information safe computing
- DReduced Instruction set computing
21CISC
- ACPU information same compound
- BComputing information same complex
- CComputing instructions set coprocessor
- DComplex Instruction set computing
22CISC is
- Aused by all laptops/desktops
- Bused by most laptops/desktops - made by Intel/AMD
- Cused by all laptops/desktops/smartphones and tabets
- Dused only in smartphones and tabets
23RISC is
- Aused in tablets/smartphones
- Bused in all devices
- Cused only in laptops
