Technical Support Interview Question
1) Name some of the latest Computer Processors?
Intel Pentium Quad Core, Intel I3, I5 and I7 processor are
some of the latest Computer Processor.
2) What does a ‘?’ sign in device manager indicate?
When this sign appears, it indicates the device is not
properly installed. Such problem arises in case of brand new plug-in
cards.
3) How you keep yourself updated with the current
technology?
I keep myself connected with social networking sites, the
first platform for any technological advancement news and also keep surfing on
the latest technology on internet.
4) What is the expected period of an average call while
dealing with the customers?
The expected period of an average call would be around 2-3
minutes, sometimes less or more depending on the problem complexity.
5) Why 8085 processor is called 8 bit processor?
It is called 8 bit processor as it has 8 bit ALU (Arithmetic
Logic Unit).
6) What is stack and can we use ROM as stack?
Stack is a portion of RAM used for saving the content of the
program counter and general purpose registers. ROM cannot be used as a
stack, as it is not possible to write on ROM.
7) What does it mean by interrupt?
To perform a particular task, interrupt is a signal send by
external device to the processor.
8) What is a Microprocessor?
A microprocessor is a program controlled device. It
retrieves the data instructions from memory and decodes them, after decoding,
it executes the instruction.
9) What is Latch?
It is a temporary storage device controlled by a timing
signal, which can store 1 or 0. It is a D-type flip flop storage device.
10) What do you mean by DHCP?
DHCP stands for Dynamic Host Configuration Protocol, it is a
network protocol, and it enables the server to assign automatically, IP address
to a computer.
11) What do you mean by OSI?
OSI stands for open system interconnection. It is a
standard description or a reference model of how message should be conveyed
between any two points within a telecommunication network. It is made up of
several layers and each layer provides services to the layer above.
12) What is TCP/IP?
TCP/IP stands for Transmission Control Protocol or Internet
protocol. It is used to connect hosts on the internet, by transferring
data over the network.
13) What are RJ45 and RJ11 connectors?
RJ45 connectors are used for LAN/internet connections while
RJ11 connectors are used for Table cable connectors.
14) What do you mean by packaging a Microprocessor?
What are the different packaging’s available?
The process of packaging a microprocessor to the computer
motherboard is known as a microprocessor. The different types of
microprocessor’s packaging are
PGA
SPGA
SECC
LGA
15) Explain the Cache memory? What is the advantage of
a processor having more cache memory?
Cache memory is the memory area between Processor and
Ram. If the cache memory increases, the speed of the system will also
increases.
16) What is over clocking? What are the advantages of
over clocking?
It is a process where the computer component is forced to
run at a higher clock rate.
The advantages of over clocking are:
Increases the CPU’s performance
It is cost-saving
Makes PC games and Applications to run faster
17) What is chipset? How is it different from processor
and motherboard?
Chipset is one of the processing devices in a
computer. It is a number of integrated circuits, designed to control how
information travels between other components and processor. It is a group of
microchip to work as a unit to perform one or more related functions. While
motherboard is where all other components like CPU, Memory, Sockets for
external connectors and drives are attached. Chipset is a built in
feature of Motherboard. While, processor is a main integrated circuit block,
which does the function according to the instruction of a computer
program. It is based on the logical, arithmetical and input/output of the
system.
18) What is heat sink and what is the use in the
system?
To lower the temperature of a device, a heat sink component
is used. It is there on the microprocessor and if it is not functioning well
then the computer will shut down automatically.
19) What is Jumper and why you need it?
Jumper is a metal bridge that closes an electric circuit. A
jumper consists of a plastic plug that fits over a pair of protruding
pins. It is used to change the board’s parameters.
20) What are the different types of DRAM?
The different types of DRAM are SRAM, VRAM, SGRAM, DDR-SDRAM
21) What might be the problem when you don’t see the
display?
Power related issues
Heat sink related issues
CPU fan related issues
Improper Jumper settings
22) What is SATA?
SATA stands for Serial Advanced Technology Attachment.
It is high speed computer bus interface designed to connect the host bus
adapters to mass storage devices, such as hard disk drives and optical drives.
