How many pins does a SIMM have?


EXPLANATION

 A SIMM, or single in-line memory module, is a type of memory module containing random-access memory used in computers from the early 1980s to the late 1990s. It differs from a dual in-line memory module, the most predominant form of memory module today, in that the contacts on a SIMM are redundant on both sides of the module. SIMMs were standardised under the JEDEC JESD-21C standard.

168 pins are used on SDRAM DIMM. 184 pins are used on DDR DIMM. There are either 30 pins or 72 pins used on SIMM. 184 pins are used on RIMM.

What does DIMM stand for?

EXPLANATION

 A DIMM or dual in-line memory module comprises a series of dynamic random-access memory integrated circuits. These modules are mounted on a printed circuit board and designed for use in personal computers, workstations and servers. DIMMs began to replace SIMMs as the predominant type of memory module as Intel P5-based Pentium processors began to gain market share.

EXPLANATION

In a computer, an interrupt request is a hardware signal sent to the processor that temporarily stops a running program and allows a special program, an interrupt handler, to run instead. Hardware interrupts are used to handle events such as receiving data from a modem or network card, key presses, or mouse movements.

 COM is the original, yet still common, name of the serial port interface on IBM PC-compatible computers. It might refer not only to physical ports, but also to virtual ports, such as ports created by Bluetooth or USB-to-serial adapters.

What kind of connectors are used to connect a PC power supply to a hard drive?

What kind of connectors are used to connect a PC power supply to a hard drive?

  • AT
  • Mini-molex
  • Molex
  • P9 
What kind of connectors are used to connect a PC power supply to a hard drive?


EXPLANATION

 Molex connector is the vernacular term for a two-piece pin and socket interconnection. Pioneered by Molex Connector Company, the two-piece design became an early electronic standard. Molex developed and patented the first examples of this connector style in the late 1950s and early 1960s. First used in home appliances, other industries soon began designing it into their products from automobiles to vending machines to mini-computers.

Which of the following is both an input and an output device?

  • Printer
  • Mouse
  • USB thumb drive
  • Keyboard 

Which of the following is both an input and an output device?

EXPLANATION

a flash drive is an output device.
A flash drive can fit into either category(input, output or storage). It simply depends on how it is used.

Which of the following RAID levels does NOT provide fault tolerance?

Which of the following RAID levels does NOT provide fault tolerance?

  • RAID 1
  • RAID 0
  • RAID 5
  • RAID 10 

Which of the following RAID levels does NOT provide fault tolerance?

EXPLANATION

RAID 0 can be used for setups like those big, read-only network file system servers, or if mounting multiple disks is not possible. In RAID 0, data files are broken down into smaller blocks, and each block is written to a separate physical disk drive. This process is known as striping and is called a striped disk array configuration. This can increase I/O performance by spreading the load evenly (more or less) across many drives and channels, so large data can be simultaneously accessed from the different drives and put together quickly, as opposed to a single drive reading a large file one chunk after another. RAID 0 offers great I/0 performance, but has little to no fault tolerance.

Who can create application data partitions for testing and troubleshooting purposes?

Who can create application data partitions for testing and troubleshooting purposes?


EXPLANATION

Application Directory Partition
In Windows Server 2003, Active Directory Domain Services support application directory partitions.
Applications and services can use application directory partitions to store application-specific data. Application directory partitions can contain any type of object, except security principals, and can be configured to replicate to any set of domain controllers in the forest.
Unlike a domain partition, an application directory partition is not required to replicate to all domain controllers in a domain and the partition can replicate to domain controllers in different domains of the forest
Application directory partitions are usually created by the applications that will use them to store and replicate data. For testing and troubleshooting purposes, members of the Enterprise Admins group can manually create or manage application directory partitions using the Ntdsutil command-line tool.
