EXAM
Administration - (correct Answer) - An administrator is in charge of some portion of the IT infrastructure.
Network administrator - (correct 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).
Database administrator - (correct 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
Security administrator - (correct Answer) - install, configure, and administer appropriate firewall security
to protect the organization's systems and to work proactively against such intrusions.
Web administrator (webmaster) - (correct 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 - (correct 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
Information technology - (correct Answer) - describes the technology infrastructure that may support
information systems, although Information Technology could also support many other types of systems
(e.g., telecommunications systems). Information Technology includes hardware, software, networks, and
databases that work together to allow an organization to manage data and information.
A computer performs four operations - (correct Answer) - IPOS
Input
Processing
Output
Storage
Parts of the CPU - (correct Answer) - ALU
Control Unit
, Registers
Memory - (correct Answer) - SCRAM
DRAM
ROM
I/O Subsystem - (correct Answer) - Input Devices
Output Devices
Storage Devices
Computer structure - (correct Answer) - {CPU (ALU, Control Unit, Registers)
System Bus
Memory(SCRAM, DRAM, ROM)}
I/O Bus
{I/O Subsystem (Input Devices, Output decides, Storage Devices)}
CPU (Central Processing Unit) - (correct Answer) - is the device that not only executes your programs'
instructions, but also commands the various components in the computer.
Memory - (correct Answer) - stores the program(s) being executed and the data that each program is
using.
short-term and long-term storage.
I/O subsystem - (correct Answer) - subsystem includes all peripheral devices (input, output, storage,
network) where storage consists of the long-term storage devices (disk drives, tape).
bus - (correct Answer) - is the device that permits information to move between each component.
The system unit - (correct 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.
Dynamic RAM (DRAM) - (correct Answer) - which is typically called main memory
Static RAM (SRAM) - (correct Answer) - which is cache memory and registers
Read only memory (ROM) - (correct Answer) - which retains its contents indefinitely
