What does FDISK do?
What does FDISK do?
- Performs low-level formatting on the hard drive
- Creates partitions on the hard drive
- Fixes bad sectors on the hard drive
- Recovers lost cluster on the hard drive
EXPLANATION
For computer file systems, fdisk is a command-line utility that provides disk partitioning functions. In versions of the Windows NT operating system line from Windows 2000 onwards, fdisk is replaced by a more advanced tool called diskpart. Similar utilities exist for Unix-like systems.
How many pins does a SIMM have?
How many pins does a SIMM have?
- 30 or 72
- 168
- 50
- 64
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?
- Difficult to install memory module
- Digital information memory module
- Digital interface memory module
- Dual in-line memory module
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.

- Floppy drive controller
- COM1
- Keyboard
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
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.
