Administration - (Answer)An administrator is in charge of some portion of the IT infrastructure.
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).
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
Security administrator - (Answer)install, configure, and administer appropriate firewall security
to protect the organization's systems and to work proactively against such intrusions.
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
Information technology - (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 - (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)}
,CPU (Central Processing Unit) - (Answer)is the device that not only executes your programs'
instructions, but also commands the various components in the computer.
Memory - (Answer)stores the program(s) being executed and the data that each program is using.
short-term and long-term storage.
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).
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.
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
BIOS - (Answer)Basic Input Output System
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.
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
Users - (Answer)The people who use the computer system
Generations of Machines - (Answer)1st generation - vacuum tubes
2nd generation - transistors
3rd generation - integrated circuits
4th generation - microprocessors
Machine language - (Answer)The lowest-level programming languages understood by
computers, representing instructions in binary (0s and 1s)
Assembly language - (Answer)specified instructions using words
High level language - (Answer)is a programming language such as C, FORTRAN, or Pascal that
enables a programmer to write programs that are more or less independent of a particular type of
computer.
Compiler - (Answer)requires that the components of the software all be defined before
compilation can begin to run all at once. Examples are C, C++, C#.
