Computer Fundamentals and System Concepts Questions

Multiple choice technology architecture
  1. XI50

  2. XS40

  3. XB60

  4. XN10

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The question asks which is NOT a DataPower box. IBM DataPower appliance models include the XI50, XS40, and XB60 among others. XN10 is not a real DataPower model number, making it the correct answer to the negative question. The naming convention for DataPower appliances follows patterns like XI50, XS40, XB60, and XG45 - XN10 doesn't fit this pattern and doesn't exist in IBM's product lineup.

Multiple choice technology architecture
  1. Hot swap

  2. Cold swap

  3. Warm swap

  4. Hot spare

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Hot swap refers to the ability to add or remove components from a system while it remains powered on and operational. This is important for systems that require high availability. Cold swap requires powering down, warm swap is a middle ground, and hot spare refers to a standby component.

Multiple choice technology
  1. Software

  2. Hardware

  3. Operating System

  4. All of the above

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Netezza is a data warehouse appliance that combines specialized hardware, proprietary software, and an operating system. It's designed as an integrated system where all components work together for high-performance analytics. This appliance approach simplifies deployment and optimization.

Multiple choice technology
  1. CPU, ROM, FPGA, Disk

  2. CPU, RAM, FPGA, Disk

  3. CPU, SMP, MPP, NIC

  4. All of the above

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

An SPU in Netezza architecture consists of a CPU for general processing, RAM for memory operations, FPGA (Field-Programmable Gate Array) for accelerated data processing, and Disk for storage. This combination enables high-performance data warehousing operations.

Multiple choice technology
  1. Field Programmable Grid Array

  2. Field Programmable Gate Array

  3. Fast Processing Gate Array

  4. None of the above

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

FPGA stands for Field Programmable Gate Array. Option A incorrectly uses 'Grid' instead of 'Gate', and Option C incorrectly expands the acronym with unrelated words.

Multiple choice technology operating systems
  1. In “My Computer”

  2. b. In documents and settings

  3. Network

  4. G drive

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The user I drive is typically a mapped network drive in enterprise environments, accessible through Network locations rather than local drives like My Computer or Documents and Settings. Network drives are shared resources stored on servers.

Multiple choice technology operating systems
  1. Z drive

  2. H drive

  3. G drive

  4. E drive

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The G drive is the network drive accessible by associates for storing and accessing work files. Z drive, H drive, and E drive typically serve other purposes (admin, system, or restricted access). This is organization-specific policy.

Multiple choice technology operating systems
  1. True

  2. False

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The question asks if you can create a drive of your own. In computing, you cannot create physical storage drives (hardware), but you can create logical drives through partitioning, mapping network drives, or creating virtual drives. However, the phrasing is ambiguous and unclear.

Multiple choice technology
  1. Computer added Device

  2. Central Attached Device

  3. Computer Aided Design

  4. Centralised And Divided

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

CAD stands for Computer Aided Design, software used for creating technical drawings and designs. Option C is correct with 'Computer' and 'Aided' (past participle) and 'Design'. Options A and B incorrectly use 'added' and 'Attached' instead of 'Aided'. Option B incorrectly uses 'Central' instead of 'Computer'. Option D is nonsensical.

Multiple choice technology operating systems
  1. kill

  2. delete

  3. shutdown

  4. stop

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The 'kill' command terminates processes by sending signals (typically SIGTERM or SIGKILL). 'delete' is for files, 'shutdown' powers down the system, and 'stop' is not a standard Unix command for process control.

Multiple choice technology
  1. Microcontroller

  2. Arthimatic Logical Unit (ALU)

  3. Control unit

  4. Register array

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

A microprocessor's core internal components are the Arithmetic Logic Unit (ALU) for performing calculations, Control Unit for instruction sequencing and decoding, and Register Array for temporary data storage during execution. A microcontroller is a complete system-on-chip that contains a microprocessor plus memory and I/O peripherals, making it fundamentally different from basic microprocessor elements.

Multiple choice technology
  1. JB (jump back)

  2. JA (jump above)

  3. JO (jump if overflow)

  4. JMP (unconditional jump)

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Standard conditional jump instructions in assembly include JA (Jump if Above), JO (Jump if Overflow), and JMP (unconditional jump). 'JB' is not a standard assembly mnemonic - the correct instruction for 'jump back' would be something like JMP with a negative offset or a loop instruction. The question asks which is NOT a jump instruction, and JB is indeed the invalid one.

Multiple choice technology
  1. 80386

  2. 80486

  3. Pentium

  4. Pentium Pro

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The Intel 80486 (1989) was the first Intel microprocessor to include on-board (L1) cache memory - it had 8 KB of unified cache. The 80386 had no on-board cache, while Pentium and Pentium Pro came later and expanded on this concept. The 486's integrated cache significantly improved performance by reducing memory access times.
