Computer Fundamentals and System Concepts

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.

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.

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.

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.

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.

Power Center Server consists of the Repository Server and Repository Database. The Repository Server manages connections and metadata storage, while the Repository Database stores all metadata objects. Repository Manager is a client tool for accessing the repository, not a server component.

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.

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.

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.

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.

Computer systems use three standard buses: Address Bus (carries memory addresses), Data Bus (carries actual data), and Control Bus (carries control signals and status information). 'Timer bus' is not a standard computer bus - timing signals are typically carried on the control bus, and timers are peripheral devices, not a bus architecture.

The Intel 4004, released in 1971, was the first commercial microprocessor and it had a 4-bit data bus. This revolutionary chip paved the way for modern computing. Later processors evolved to 8-bit (8080), 16-bit (8086), and 32-bit (80386) architectures, but the first microprocessor was indeed 4-bit.

Research In Motion (RIM), the company behind BlackBerry devices, used Intel processors in their early smartphones. Intel was a major processor manufacturer that supplied chips for various mobile devices.

Running a system backup while infected copies the virus to backup media, contaminating your clean restore point. When virus is active, you should avoid file operations that propagate infection. Defragmentation (A) and moving files (D) are disk operations; shutdown (C) may be needed for disinfection but isn't prohibited.
