Explanation: This is the gate transfer notation, which indicates the usage of switches to control the flow of data.
2. The completion of the memory operation is indicated using ______ signal.
a) MFC
b) WMFC
c) CFC
d) None of the mentioned
View Answer
Explanation: MFC stands for Memory Function Complete.
3. _________ signal enables the processor to wait for the memory operation to complete.
a) MFC
b) TLB
c) WMFC
d) ALB

4. The small extremely fast RAM is called as ________
a) Cache
b) Heaps
c) Accumulators
d) Stacks
View Answer
Explanation: A cache speeds up the execution of a program significantly, by keeping a copy of data and instructions locally in the CPU.
5. The main virtue for using a single Bus structure is ________
a) Fast data transfers
b) Cost-effective connectivity and speed
c) Cost-effective connectivity and ease of attaching peripheral devices
d) None of the mentioned
View Answer
Explanation: The advantage of single bus architecture is the simplicity of the design wherein all the components will fit on the same bus and hence it’s cost-effective. It may not be very fast though.
6. To extend the connectivity of the processor bus we use ______
a) PCI bus
b) SCSI bus
c) Controllers
d) Multiple buses
View Answer
Explanation: The PCI bus is generally the system bus on the motherboard and it is used to connect the CPU, Memory, and peripheral devices using other buses or channels or controllers.
7. The bus used to connect the monitor to the CPU is ____________
a) PCI bus
b) SCSI bus
c) Memory bus
d) Rambus
View Answer
Explanation: PCI bus connects CPU to the Display Unit whereas SCSI bus is used to connect to storage devices.
8. The IDE bus is used to connect ___________
a) RAM and processor
b) GPU and processor
c) Both Harddisk and CD/DVD drives and Processor
d) Only CD/DVD drives and Processor
View Answer
Explanation: IDE bus is used to connect to peripheral devices like hard disks and CD/DVD drives using master-slave mode.
9. ANSI stands for _____________
a) American National Standards Institute
b) American National Standard Interface
c) American Network Standard Interfacing
d) American Network Security Interrupt
View Answer
Explanation: American National Standards Institute or ANSI is one of the prime organizations in the US which works towards the standardization of various Technologies in Computer-Sciences and other technology fields.
10. IBM developed a bus standard for their line of computers ‘PC-AT’ called ________
a) IB bus
b) M-bus
c) ISA
d) None of the mentioned
View Answer
Explanation: “Industry Standard Architecture” or ISA bus was designed by IBM way back in the days of 8-bit or 16-bit computing platforms as a bus for Personal Computers.
