INTRODUCTION TO IT PRE-ASSESSMENT
QUESTIONS WITH ANSWERS
Administration - ANSWER-An administrator is in charge of some portion of the
IT infrastructure.
Web administrator (webmaster) - ANSWER-also known as a webmaster, but more
precisely referred to as a web server administrator. This role is responsible for
maintaining web storages, which differs from the development of web storage.
Specifically, the web administrator must install, configure, maintain, secure, and
troubleshoot the web server.
Define Information Technology - ANSWER-IT is a term used to describe several
aspects: the task of gathering data and processing it into information, the ability to
disseminate information using technology, the technology itself that permits these
tasks, and the collection of people who are in charge of maintaining the IT
infrastructure (the computers, the networks, and the operating systems).
Generically, we will consider IT to be the technology used in creating,
maintaining, and making information accessible. In other words, IT combines
people with computing resources, software, data, and computer networks
Network administrator - ANSWER-oversees all aspects of the computer network.
The network administrator's duties include physically laying down cable, making
connections, and working with the network hardware (for instance, routers and
switches).
Security administrator - ANSWER-install, configure, and administer appropriate
firewall security to protect the organization's systems and to work proactively
against such intrusions.
A computer performs four operations - ANSWER-IPOS
Input
Processing
Output
Storage
,Parts of the CPU - ANSWER-ALU
Control Unit
Registers
Memory - ANSWER-SCRAM
DRAM
ROM
I/O Subsystem - ANSWER-Input Devices
Output Devices
Storage Devices
Computer structure - ANSWER-{CPU (ALU, Control Unit, Registers)
System Bus
Memory (SCRAM, DRAM, ROM)}
I/O Bus
{I/O Subsystem (Input Devices, Output decides, Storage Devices)}
I/O subsystem - ANSWER-subsystem includes all peripheral devices (input,
output, storage, network) where storage consists of the long-term storage devices
(disk drives, tape).
Database administrator - ANSWER-focus on the design, development, and support
of database management systems (DBMSs). Tasks will include installation,
maintenance, performance analysis, and troubleshooting as with the other
administrative areas
Bus - ANSWER-is the device that permits information to move between each
component.
The system unit - ANSWER-is a core feature of notebooks, tablets, smartphones,
and other types of computers; therefore, it comes in a variety of shapes and sizes.
The system unit contains various components that enable the PC system to run
programs and complete other important functions. Various different types of
computers are likely to have many of the same components. These include the
case, which is a protective covering, internal bays and slots that grip the internal
, components, buses, which are the circuitry and electrical channels that enable
communication among the electronic components, bays (external openings) and
ports that connect peripherals, and lights and indicators that show the computer is
turned on.
CPU (Central Processing Unit) - ANSWER-is the device that not only executes
your programs' instructions, but also commands the various components in the
computer.
Dynamic RAM (DRAM) - ANSWER-which is typically called main memory
Static RAM (SRAM) - ANSWER-which is cache memory and registers
Read only memory (ROM) - ANSWER-which retains its contents indefinitely
Memory - ANSWER-stores the program(s) being executed and the data that each
program is using.
short-term and long-term storage.
Hardware - ANSWER-The physical components of the computer
Software - ANSWER-The programs and other operating information used by the
computer
Network - ANSWER-A collection of computers and resources connected by
various media so they can communicate with each other
Hard drive - ANSWER-store data even when the computer is turned off
Peripheral devices - ANSWER-components that are located outside the system unit
yet are connected physically or wirelessly to it.
Users - ANSWER-The people who use the computer system
BIOS - ANSWER-Basic Input Output System
